In this study, we first report the anti-invasive effect of ethylacetate extract from Antrodia cinnamomea (EAC) fruiting
bodies in the human liver cancer cell line PLC/PRF/5. Treatment with EAC decreased the cancer invasion of PLC/PRF/5
cells in a dose-dependent manner. This effect was strongly associated with a concomitant decrease in either the level or
activity of VEGF, MMP-2, MMP-9 and MT1-MMP, and an increase in the expression of TIMP-1 and TIMP-2. EAC
inhibited constitutively activated and inducible NF-kappaB in both its DNA-binding activity and transcriptional activity.
Furthermore, EAC also inhibited the TNF-alpha-activated NF-kappaB-dependent reporter gene expression of MMP-9 and
VEGF, and the invasion of cancer cells. EAC also exhibited an inhibitory effect on angiogenesis in a Matrigel Plug
Angiogenesis Assay. Further investigation revealed that EAC's inhibition of cancer cell growth and invasion was also
4
evident in a nude mice model. Our results indicate that EAC inhibits the activation of NF-kappaB, and may provide a
molecular basis for drug development using EAC as an anti-invasive agent in the prevention and treatment of cancer.

Submerged cultures were used to identify growth-limiting nutrients by Antrodia cinnamomea strains. The mycelial biomass
and EPS production by A. cinnamomea BCRC 35396 were markedly higher than other A. cinnamomea strains. A relatively
high C/N ratio was favorable for both the mycelial growth (5.41g/l) and EPS production (0.55g/l); the optimum ratio was 40.
The glucose was available utilized preferentially for mycelial growth, rather than for EPS production. Flushing the culture
medium with nitrogen had a stimulating effect on both mycelial growth and EPS production. In addition, peptone, yeast
extract and malt extract appeared to be important and significant component for EPS production. Phosphate ion, magnesium
ion and thiamine were probably not essential for mycelial growth. By optimizing the effects of additional nutrition, the
results showed that 5% (w/v) glucose, 0.8% (w/v) peptone, 0.8% (w/v) yeast extract, 0.8% (w/v) malt extract, 0.03% (w/v)
KH(2)PO(4), 0.1% (w/v) MgSO(4).7H(2)O and 0.1% (w/v) thiamine could lead to the maximum production of EPS
(1.36g/l).

3: Apoptotic effects of Antrodia cinnamomea fruiting bodies extract are mediated through calcium and
calpain-dependent pathways in Hep 3B cells.

Antrodia cinnamomea is well known in Taiwan as a traditional medicine for treating cancer and inflammation. The purpose
of this study was to evaluate the apoptotic effects of ethylacetate extract from A. cinnamomea (EAC) fruiting bodies in Hep
3B, a liver cancer cell line. EAC decreased cell proliferation of Hep 3B cells by inducing apoptotic cell death. EAC
treatment increased the level of calcium (Ca2+) in the cytoplasm and triggered the subsequent activation of calpain and
caspase-12. EAC also initiated the mitochondrial apoptotic pathway through regulation of Bcl-2 family proteins expression,
release of cytochrome c, and activation of caspase-9 in Hep 3B cells. Furthermore, the mitochondrial apoptotic pathway
amplified the calpain pathway by Bid and Bax interaction and Ca2+ translocation. We have therefore concluded that the
molecular mechanisms during EAC-mediated proliferation inhibition in Hep 3B cells were due to: (1) apoptosis induction,
(2) triggering of Ca2+/calpain pathway, (3) disruption of mitochondrial function, and (4) apoptotic signaling being
amplified by cross-talk between the calpain/Bid/Bax and Ca2+/mitochondrial apoptotic pathways.

Mycelia of Antrodia cinnamomea were extracted with chloroform and hot water. A neutral polysaccharide named ACN2a
separated from the water extract was purified using 10% CCl3COOH, and repeated column chromatography on HW-65 and
DE-52 cellulose. Its structure was determined by chemical and spectroscopic analyses. ACN2a was composed of Gal, Glc,
Fuc, Man and GalN (in the ratio 1:0.24:0.07:0.026:faint), in which an alpha-D-(1-->6)-Gal linkage accounted for 73% of all
linkages. The ratio of branch points was about 16% of the total residual numbers, and branches were attached to C-2 of
galactosyl residues of the main chain. ACN2a had an average molecular weight of 12.9x10(5) Daltons, [alpha]D25=+115
degrees (c=0.44, H2O); [eta]=0.0417dl.g-1, Cp=0.2663 cal/(g. degrees C). The hepatoprotective effect of ACN2a was
5
evaluated using a mouse model of hepatic injury that was induced by Propionibacterium acnes (P. acnes) and
lipopolysaccharide (LPS). The administration of ACN2a (0.4, 0.8 g/kg/d, p.o.), significantly prevented increases in serum
aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzyme activities in mice treated with P. acnes-LPS,
indicating hepatoprotective activity in vivo.

The nutritional medium requirement for biomass and triterpenoid production by Antrodia cinnamomea AC0623 strain was
optimized. Box-Behnken was applied to optimize biomass and triterpenoid production. According to response surface
methodology (RSM), the optimum concentrations of N-source were determined. The results indicate that when a submerged
culture in shake flasks was operated at 28 degrees C, initial pH 5.5, and rotation speed 105 rpm, the biomass and
triterpenoid content in dry basis could be increased to 3.20% (w/w) and 31.8 mg/g, respectively. The experiments were
further scaled up to 100- and 700-l fermentors. Higher content of triterpenoids (63.0 mg/g) was obtained in 700-l
fermentations by means of the control of cultural conditions and the modification of medium composition based on the
RSM.

6: Adenosine as an active component of Antrodia cinnamomea that prevents rat PC12 cells from serum
deprivation-induced apoptosis through the activation of adenosine A2A receptors.

Antrodia cinnamomea (formerly named Antrodia camphorata) is a rare medicinal fungus. We previously reported that it
exhibits antioxidative, vasorelaxative, anti-inflammatory, and anti-angiogenic effects. When serum deprivation-induced
apoptosis in neuronal-like PC12 cells was used as a stress model, the extract of A. cinnamomea displayed effectiveness in
preventing serum-deprived apoptosis. Since our previous data show that the extract of A. cinnamomea contains adenosine
(ADO), we attempt to investigate if the active component is ADO and to identify its targeting site in this study. After
pre-incubation with ADO deaminase, neither ADO nor the extract of A. cinnamomea exerted any protection, demonstrating
that the active component of A. cinnamomea is ADO. Furthermore, an ADO A(2A) receptor (A(2A)-R) antagonist was used
and was able to block the protective effects of ADO and the extract of A. cinnamomea, demonstrating that the ADO
targeting site in this model is A(2A)-R. Taken together, the protective effect of A. cinnamomea is owed to its active
component, ADO, which acts through activation of A(2A)-R to prevent serum deprivation-induced PC12 cell apoptosis.

7: Cultivating conditions influence exopolysaccharide production by the edible Basidiomycete Antrodia cinnamomea
in submerged culture.

Antrodia cinnamomea is a medicinal fungus that has been used in Taiwan as a traditional medicine for the treatment of
tumorigenic diseases. We prove that controlling the culturing conditions (i.e., temperature and pH) and modifying the
composition of the medium (i.e., carbon, nitrogen, mineral sources and vitamins) can dramatically enhance the production
of the exopolysaccharide of A. cinnamomea. We have found that the temperature, initial pH, and agitation time are all
6
critical for exopolysaccharide production during the cultivation of A. cinnamomea in submerged cultures; our optimized
conditions were 28 degrees C, pH 5.5, and 14 days, respectively. In addition, when optimizing the effects of additional
nutrition, we found that 5% (v/v) glucose, 0.5% (v/v) calcium nitrate, 0.1% (v/v) ferrous sulfate, and 0.1% (v/v) nicotinic
acid led to the greatest production of exopolysaccharides; the exopolysaccharide production, mycelial biomass and specific
product yield reached 0.49 g/l, 2.60 g/l and 0.19 g/g, respectively. The results indicate that nutrients can be utilized to
improve the production of exopolysaccharide and that good mycelial growth does not seem to be a determining factor for a
high production yield of exopolysaccharide in A. cinnamomea.

Extracted polysaccharides from medicinal fungi, including Antrodia cinnamomea, Antrodia malicola, Antrodia xantha,
Antrodiella liebmannii, Agaricus murrill, and Rigidoporus ulmarius, were investigated for their effects on vascular
endothelial growth factor (VEGF)-induced tube formation in endothelial cells (ECs). Chemical analysis revealed that
myo-inositol, sorbitol, fucose, galactosamine, glucosamine, galactose, glucose, and mannose were the neutral sugars in
these polysaccharides. These fungal polysaccharides showed no toxicity to ECs. For the inhibition of endothelial tube
formation, extracted polysaccharides from A. xantha and R. ulmarius were shown to produce greater inhibition compared to
those from other fungi. Fucose, glucose and mannose were the predominant monosaccharides from these two fungi. These
results suggest that monosaccharides may play a role in the inhibitory effect of these fungi on endothelial tube formation. In
contrast to the inhibition on tube formation from polysaccharides of A. cinnamomea and A. malicola, polysaccharides from
A. xantha and R. ulmarius, with molecular weight between 2693-2876 and 304-325 kDa, were critical for this inhibitory
activity. Our results show that polysaccharides isolated from A. xantha and R. ulmarius provide greater antiangiogenesis
than those from commercialized A. murrill (Brazilian mushroom) and A. cinnamomea. These studies provide a basis for the
potential development of these polysaccharides for antiangiogenesis usage.

The main purposes of this study were to investigate the regulation of polysaccharides isolated from A. cinnamomea on
vascular endothelial growth factor (VEGF)-induced cyclin D1 expression and down stream signaling pathway that may
correlate with their anti-angiogenc effects in endothelial cells (ECs). Crude and fractionated polysaccharides (Fra-1 to Fra-4)
of A. cinnamomea showed slightly toxicity to ECs as compared with their inhibition concentration on angiogenic-related
gene expression. The crude extract and fractionated fractions, except for Fra-2, of A. cinnamomea polysaccharides
significantly decreased VEGFR2 phosphorylation on tyrosine 1054/1059, cyclin D1 promotor activity, and protein
expression induced by VEGF. Crude extract of A. cinnamomea polysaccharides inhibited the binding of VEGF to
KDR/flk-1 in a dose-dependent manner. These results indicated that inhibition of VEGF interaction with VEGF receptor 2
is the mechanism serves A. cinnamomea as a protective mechanism composing the anti-angiogenesis function. Furthermore,
A. cinnamomea polysaccharides also blocked VEGF-induced migration and capillary-like tube formation of ECs on
Matrigel. Taken together, these results indicate that A. cinnamomea polysaccharides inhibit cyclin D1 expression through
inhibition of VEGF receptor signaling, leading to the suppression of angiogenesis.

12: Fermented Antrodia cinnamomea Extract Protects Rat PC12 Cells from Serum Deprivation-Induced Apoptosis:
The Role of the MAPK Family.
J Agric Food Chem. 2008 Jan 11 [Epub ahead of print]
Lu MK, Cheng JJ, Lai WL, Lin YJ, Huang NK.
Antrodia cinnamomea (formerly A. camphorata) has recently and commercially been used in the formulation of
nutraceuticals and functional foods in Taiwan. Because of its diverse properties, the neuroprotective effect was investigated
using a fermented A. cinnamomea extract in this study. Serum deprivation-induced apoptosis in neuronal-like
pheochromocytoma (PC12) cells was used as a cell stress model, and it was found that A. cinnamomea was effective in
preventing serum-deprived apoptosis according to results of an MTT assay and Hoechst staining. Serum deprivation
resulted in decreased phosphorylation of extracellular signal-regulated kinase (ERK) and increased phosphorylations of
c-Jun NH 2-terminal kinase (JNK) and p38, of the family of mitogen-activated protein kinases (MAPKs); however, A.
cinnamomea reversed these phenomena, supporting the antagonistic effects between ERK and JNK-p38 in regulating cell
survival. The previously identified active component of A. cinnamomea, adenosine (ADO), also exerted the same effects as
A. cinnamomea in preventing apoptosis and regulating phosphorylations of MAPKs. Although an inhibitor of the ERK
upstream activator blocked A. cinnamomea-induced ERK phosphorylations, it failed to block the protection of A.
cinnamomea and ADO. A protein kinase A (PKA) inhibitor blocked the protection by both A. cinnamomea and ADO. Both
JNK and p38 inhibitors were effective in preventing the phosphorylations of JNK and p38 and serum deprivation-induced
apoptosis. Collectively, A. cinnamomea prevented serum deprivation-induced PC12 cell apoptosis through a
PKA-dependent pathway and by suppression of JNK and p38 activities.

A partial (634bp) cDNA clone, AF1229, obtained from ESTs of solid-cultured basidiomes of Antrodia cinnamomea is
homologous to the lipase gene in Rhizomucor miehei. 5'-RACE and 3'-RACE amplification showed that the full-length
lipase gene, Ac-LIP, has a 912bp open reading frame (ORF), a 183bp 5' non-coding region, and a 144bp 3' non-coding
region. Ac-LIP contains the lipase consensus sequence, VTVVGHSLGA, and encodes a 303-amino acid polypeptide that
8
appears to be an extracellular protein with a calculated molecular mass of 31.8kDa. RT-PCR analysis suggested that Ac-LIP
was strongly expressed during the basidiomatal formation stage of A. cinnamomea. When over-expressed in Escherichia
coli, Ac-LIP yielded a protein that was capable of performing hydrolysis of trilinolein by gas chromatography/mass
spectrometry (GC/MS) analysis. A. cinnamomea lipase represents the first enzyme of the lipase family from a

On cultivation of the fungus Antrodia cinnamomea (BCRC 36799) on a medium, the mycelium was extracted and evaluated
for nitric oxide (NO) inhibitory activity. Bioactivity-directed fractionation led to the isolation of two new maleimide
derivatives, antrocinnamomins A (1) and B (2), and two new maleic anhydride derivatives, antrocinnamomins C (3) and D
(4), along with three known compounds, 3-isobutyl-4-[4-(3-methyl-2-butenyloxy)phenyl]furan-2,5-dione (5),
3-isobutyl-4-[4-(3-methyl-2-butenyloxy)phenyl]-1H-pyrrole-2,5-dione (6), and
3-isobutyl-4-[4-(3-methyl-2-butenyloxy)phenyl]-1H-pyrrol-1-ol-2,5-dione (7). Structural elucidation of compounds 1-4 was
carried out by spectroscopic data. Compound 1 displayed significant inhibitory effect on nitric oxide (NO) production.

cDNAs specifically expressed at the basidiome stage were isolated by using PCR-selected cDNA subtraction in order to
study gene regulation during porous-hymenium basidiomatal formation in Antrodia cinnamomea. blastx results suggested
that most of the expressed sequence tags (52.4-69.5%) had no significant protein homology to genes from other published
living things. cDNAs particularly expressed at different growing conditions were identified using cDNA microarray
analysis. Reverse transcriptase PCR analyses confirmed that the clone putative to P-type ATPase, various cytochrome
P450s and some unknown genes were abundant at natural basidiomes while endoglucanase was abundant at the tissue from
artificial medium.

This study describes the development of an efficient and reliable activation tagging system for the medicinal fungus Antrodia
cinnamomea. For successful Agrobacterium tumefaciens-mediated transformation, different parameters were considered. The
Agrobacterium concentration of 5x10(8)cfuml(-1), 1mm acetosyringone, 25-d-old mycelia at 0.2gml(-1), and co-culture
period of 6d were found to be the most optimal conditions for enhancing the transformation efficiency. The mitotic stability of
transferred DNA (T-DNA) was demonstrated by growing eight randomly selected putative transformants in malt extract agar
medium for five subcultures. Insertion of T-DNA into the genome of transformants was confirmed by PCR and Southern
hybridization. Results showed that 88% of the mutants contained a single T-DNA insertion. Two of the mutants were observed
with different triterpenoid profiles compared with the untransformed cultures. Our results suggest a new functional genomics
approach to tag the triterpenoid biosynthesis genes in A. cinnamomea.

Antrodia cinnamomea is a highly valued folk medicine used for liver cancer, a disease often caused by the long term infection
of hepatitis C virus (HCV). In the present study, the maleic and succinic acid constituents (antrodins A-E) of this medicinal
fungus, the in vivo metabolites of antrodin C and the analogue of one of the metabolites were tested for their inhibitory activity
on HCV protease. Most of the compounds showed potent inhibitory activity, with antrodin A being the most potent (IC(50) =
0.9 microg/mL). Antrodin A was isolated as one of the constituents of A. cinnamomea and was also detected as an in vivo
metabolite of the major constituent antrodin C. The mode of inhibition for antrodin A on HCV protease was revealed by a
Lineweaver-Burk plot as competitive inhibition. These results strongly support the use of this folk medicine for liver cancer
and HCV infection which is a global problem. Copyright (c) 2008 John Wiley & Sons, Ltd.

Mycelia of Antrodia cinnamomea (AC), an edible fungus native to Taiwan, were produced by submerged fermentation with
various fermentation times in 250 mL, 5 and 500 L fermentors and were evaluated for the effect of fermentation products on
the viabilities of Hep3B and HepG2 hepatoma cells and normal primary rat hepatocytes. The results showed that the ethanolic
extracts of AC mycelia (from 250 mL fermentation for 8 wk and 5 and 500 L fermentations for 4 wk) possessed high
antihepatoma activity. The IC(50) of ethanolic extract of AC mycelia fermented for 8 wk in a 250 mL fermentor against
Hep3B and HepG2 cells were 82.9 and 54.2 microg/mL, respectively. Furthermore, the IC(50) for Hep3B and HepG2, treated
with ethanolic extract of AC mycelia fermented for 4 wk in the 5 L fermentor were 48.7 and 3.8 microg/mL, respectively.
Those treated with ethanolic extract of AC mycelia fermented for 4 wk in the 500 L fermentor were 36.9 and 3.1 microg/mL,
respectively. No adverse effects of all samples on normal primary rat hepatocytes were observed.

A novel ligninolytic peroxidase gene (ACLnP) was cloned and characterized from a poroid brown-rot fungus, Antrodia
cinnamomea. The genomic DNA of the fungus harboured two copies of ACLnP, with a length of 2111 bp, interlaced with
12 introns, while the full-length cDNA was 1183 bp, with a 66 bp signal peptide and an ORF of 990 bp. The
three-dimensional molecular structure model was comparable to that of the versatile peroxidase of Pleurotus eryngii.
ACLnP was cloned into vector pQE31, successfully expressed in Escherichia coli strain M15 under the control of the T5
promoter and produced a non-glycosylated protein of about 38 kDa, pI 5.42. The native and recombinant ACLnP was
capable of oxidizing the redox mediator veratryl alcohol, and also decolorized bromophenol blue and 2,6-dimethoxyphenol
dyes, implicating a functional extracellular peroxidase activity. The significance of discovering a functional ACLnP gene in
A. cinnamomea in terms of wood degradation and colonization capacity in its unique niche is discussed.

MMH01 is a compound isolated from Antrodia cinnamomea. MMH01 markedly inhibited growth of human leukemia U937
and pancreatic cancer BxPC3 cells. It resulted in distinct patterns of cell cycle distribution in U937 (G2/M, sub-G1 and
polyploidy) and BxPC3 cells (G0/G1 and sub-G1). The modes of cell death in U937 cells include apoptosis and mitotic
catastrophe, whereas apoptosis-associated events or necrosis in BxPC3 cells. Neither mitochondrial membrane
permeabilization nor caspase dependence was noted. Proteins involving mitotic catastrophe-associated cell death such as
cyclin B1 and checkpoint kinase 2 were activated in U937 cells. Only slight to moderate viability inhibition was noted to
human monocytes, the normal counterpart of these myeloid leukemic cells. In conclusion, MMH01 possesses cytotoxicity
against human leukemia and pancreatic cancer cells.

ETHNOPHARMACOLOGICAL RELEVANCE: Antrodia cinnamomea is a popular medicinal mushroom in Taiwan that
has been widely used for treatment of various cancers and liver diseases. AIM OF THE STUDY: This study aimed to
investigate the immunomodulatory effect on angiogenesis of polysaccharides from mycelia of Antrodia cinnamomea
(PMAC). MATERIALS AND METHODS: PMAC were extracted in boiling water, precipitated with 95% ethanol, and
separated into four different molecular weights (<5, 5-30, 30-100, > 100 kDa). Tube formation and chorioallantoic
membrane (CAM) assay were used to determine the in vitro and ex vivo anti-angiogenic effects. RESULTS: Only the
PMAC-mononuclear cells (MNCs)-conditioned medium (CM) with MW > 100 kDa significantly and
concentration-dependently decreased the secretion of vascular endothelial growth factor in human leukemia cells and
inhibited the matrigel tube formation in human umbilical vein endothelial cells. Similarly only the PMAC-MNC-CM with
MW > 100 kDa significantly and concentration-dependently increased the levels of interleukin (IL)-12 and
interferon-gamma (IFN-gamma). In addition, the ex vivo CAM assay revealed that only the PMAC with MW>100 kDa
significantly and dose-dependently inhibited neovascularization. CONCLUSIONS: PMAC with MW > 100 kDa are
anti-angiogenic in vitro and ex vivo, and the effects are likely through immunomodulation.

Dendritic cells (DC) play a central role in the initiation and regulation of immune responses. Increasing evidence has
indicated that manipulation of DC can serve as a therapeutic mechanism for immunomodulation. In this study we tested
some unique compounds isolated from Antrodia cinnamomea, a medicinal fungus in Taiwan, on mouse bone
marrow-derived DC activation. A triterpenoid methyl antcinate K (me-AntK) promoted DC maturation by enhancing the
expression of MHC class II, CD86, and reducing the endocytosis. TNF-alpha, MCP-1, and MIP-1beta were secreted by DC
after me-AntK treatment, indicating augmentation of innate immunity by me-AntK. Interestingly, the me-AntK-activated
DC induced Ag-specific T-cell proliferation and facilitated Th2 differentiation. Examining signaling responses, we found
that me-AntK treatment uniquely activated JNK and ERK in DC. Our results demonstrate that me-AntK is the first natural
triterpenoid to promote the ability of DC to prime Th2 responses. This suggests that me-AntK can potentially be applied to
enhance immune responses and modulate DC function in immunotherapy.

Mago nashi (Mago) and Y14 proteins, highly conserved among eukaryotes, participate in mRNA localization and splicing,
and as such play important roles in oogenesis, embryogenesis and germ-line sex determination during animal development.
Here we identified mago (Acmago) and Y14 (AcY14) homologues derived from Antrodia cinnamomea. Acmago encodes
149 amino acids and AcY14 encodes 168 amino acids. Multiple amino acid sequence alignment as well as secondary and
tertiary structure prediction showed that AcMago and AcY14 have similar protein structure to the reported crystal structures
of other Mago and Y14 proteins. During fungal development both Acmago and AcY14 genes were abundantly expressed in
natural basidiomes. This is the first report of the molecular characterization and expression analysis of the mago and Y14
genes from fungi.

Abstract Aims: A novel lysophospholipase (LysoPL) from the basidiomycetous fungi Antrodia cinnamomea named
ACLysoPL was cloned, heteroexpressed in Escherichia coli and characterized. Methods and Results: The gene encoding
ACLysoPL was obtained from expressed sequence tags from A. cinnamomea. The full length of this gene has a 945 -bp
open reading frame encoding 314 amino acids with a molecular weight of 35.5 kDa. ACLysoPL contains a lipase consensus
sequence (GXSXG) motif and a Ser-His-Asp catalytic triad. A putative peroxisomal targeting signal type 1 was found in the
C-terminal. Heterologous expression of ACLysoPL in E. coli showed that the enzyme preferentially hydrolyses long-chain
acyl esterases at pH 7 and 30 degrees C. ACLysoPL is a psychrophilic enzyme about 40% of whose maximum activity
remained at 4 degrees C. The LysoPL activities with lysophospholipids as substrate were analysed by gas
chromatography/mass spectrometry. Conclusion: We have identified and characterized a gene named ACLysoPL encoding
a protein performing LysoPL and esterase activities. Significance and Impact of the Study: This is the first LysoPL of A.
cinnamomea identified and characterized at the molecular level.

Antrodia cinnamomea is an expensive medicinal fungus that grows only inside the rotten trunk of Cinnamomum kanehirae .
In vitro culture of A. cinnamomea fruiting body is difficult and, therefore, of value for further investigation. To study
whether the fructification of A. cinnamomea is strain dependent in artificial media, we grew four different A. cinnamomea
strains on malt extract agar (MEA) media. The standard MEA and a series of dilution of the MEA nutrient components were
made to culture A. cinnamomea. The formation of fruiting body was determined by visual and microscopic observation on
A. cinnamomea's porous morphogenesis and HPLC analysis. All A. cinnamomea strains cultured grew best in 50% MEA,
but carried different capabilities of fructification. In addition, we studied four antioxidation- or senescence-related genes,
including a cytochrome P450, a glutathione-S-transferase, a peroxiredoxin, and a manganese superoxide dismutase. We
found both cytochrome P450 and glutathione-S-transferase were expressed 3.66- and 2.75-fold in fruiting body compared
with mycelium, respectively, and perxoiredoxin and manganese superoxide dismutase were found with similar expressions
in both fruiting body and mycelium.

Abstract: Sterol 14alpha-demethylase (CYP51) is one of the key enzymes for sterol biosynthesis in fungi; it is widely
distributed in all members of the cytochrome P450 superfamily. In this study, AcCyp51, encoding a cytochrome P450 sterol
14alpha-demethylase, was obtained from the sequences of EST libraries of Antrodia cinnamomea by using 5' RACE and
genome walking methods. The open reading frame of AcCyp51 is 1635 bp and encodes 544 amino acids. The recombinant
protein of AcCYP51 fused with glutathione-S-transferase from Escherichia coli revealed the demethylating activity by using
lanosterol as substrate and GC-MS analysis. Gene expression levels of AcCYP51 were higher in natural basidiomes than in
other cell types. Transcription of AcCYP51 increased in various culture conditions including adding squalene, lanosterol,
itroconazole, and oleic acid as inducers. These reveal the important functions of AcCYP51 in basidiomatal formation and
suggest that it might participate in other biological processes.

Abstract:
BACKGROUND: Antrodia cinnamomea is known for its antihepatoma activity, yet the identity of its active compound was
unclear. In this study, a 5-ton fermenter was used to prepare sufficient mycelium of A. cinnamomea for active compound
isolation and identification.
RESULTS: Using antiproliferative activity toward HepG2 cells as guidance in the isolation process, 4-acetylantroquinonol
B was purified and identified to be the major bioactive compound of A. cinnamomea cultivated by submerged fermentation.
The median effective doses (EC(50)) of 4-acetylantroquinonol B for HepG2 cells were 0.10 +/- 0.00 and 0.08 +/- 0.00
microg mL(-1) for 72 and 96 h treatments, respectively. The selective indices of 4-acetylantroquinonol B were 100 and 125
for 72 and 96 h treatments, respectively, indicating that this compound had high selective activity for hepatoma cells.
CONCLUSION: 4-Acetylantroquinonol B is the major antihepatoma constituent of Antrodia cinnamomea mycelium
produced by submerged fermentation.

Abstract: Antrodia cinnamomea (Ac) is a medicinal mushroom widely used for the treatment of abdominal pain,
hypertension and hepatocellular carcinoma, but subchronic toxicity of this material has not yet been investigated. This
present study was conducted to assess the 90-day oral toxicity of A. cinnamomea from submerged culture in male and
female Sprague-Dawley (SD) rats. Eighty rats were divided into four groups, each consisting of ten male and ten female rats.
Test articles were administered by oral gavage to rats at 3000, 2200 and 1500mg/kg BW/day for 90 consecutive days and
reverse osmosis water was used as control. All animals survived to the end of the study. During the experiment period, no
abnormal changes were observed in clinical signs, body weight and ophthalmological examinations. No significant
differences were found in urinalysis, hematology and serum biochemistry parameters between the treatment and control
groups. Necropsy and histopathological examination indicated no treatment-related changes. According to the above results,
the no-observed-adverse-effect level (NOAEL) of Antrodia cinnamomea is identified to be greater than 3000mg/kg BW/day
in Sprague-Dawley rats.

Abstract: Three different solvent partitions (n-hexane, ethyl acetate [EtOAc] and n-BuOH) of the culture broth from
Antrodia cinnamomea were assayed with two different radical scavenging methods: 1,1-diphenyl-2-picrylhydrazyl (DPPH)
free radical scavenging and superoxide radical scavenging (SOD) assay. The EtOAc layer exhibited the best antioxidant
activity. Two major antioxidant metabolites were isolated from the active EtOAc layer. The antioxidant activities of
compounds 1-6 were further evaluated by DPPH, SOD and trolox equivalent antioxidant capacity (TEAC) assays.
Compounds 3 and 5 showed stronger free radical scavenging than the reference BHA, ED(50) = 1.36 and 34.24 µM.
Compound 5 displayed moderate SOD activity (ED(50) = 310.0 µM), and its antioxidant capacity of TEAC value was 2.2

Abstract:
AIM OF THE STUDY: In recent years, the medicinal mushroom Antrodia cinnamomea, known as "niu-chang chih" has
received much attention with regard to its possible health benefits; especially its hepatoprotective effects against various
drugs, toxins, and alcohol induced liver diseases. However, the molecular mechanism underlying this protective effect of
Antrodia cinnamomea and its active compound antroquinonol was poorly understood. In the present study we evaluated to
understand the hepatoprotective efficacy of antroquinonol and ethanolic extracts of mycelia of Antrodia cinnamomea
(EMAC) in vitro and in vivo.
MATERIALS AND METHODS: The protective mechanism of antroquinonol and EMAC against ethanol-induced
oxidative stress was investigated in cultured human hepatoma HepG2 cells and ICR mice model, respectively. HepG2 cells
were pretreated with antroquinonol (1-20µM) and oxidative stress was induced by ethanol (100mM). Meanwhile, male ICR
mice were pretreated with EMAC for 10 days and hepatotoxicity was generated by the addition of ethanol (5g/kg). Hepatic
enzymes, cytokines and chemokines were determined using commercially available assay kits. Western blotting and
real-time PCR were subjected to analyze HO-1 and Nr-2 expression. EMSA was performed to monitor Nrf-2 ARE binding
activity. Possible changes in hepatic lesion were observed using histopathological analysis.
RESULTS: Antroquinonol pretreatment significantly inhibited ethanol-induced AST, ALT, ROS, NO, MDA production and
GSH depletion in HepG2 cells. Western blot and RT-PCR analysis showed that antroquinonol enhanced Nrf-2 activation and
its downstream antioxidant gene HO-1 via MAPK pathway. This mechanism was then confirmed in vivo in an acute ethanol
intoxicated mouse model: serum ALT and AST production, hepatocellular lipid peroxidation and GSH depletion was
prevented by EMAC in a dose-dependent manner. EMAC significantly enhanced HO-1 and Nrf-2 activation via MAPKs
consistent with in vitro studies. Ethanol-induced hepatic swelling and hydropic degeneration of hepatocytes was
significantly inhibited by EMAC in a dose-dependent manner.
CONCLUSIONS: These results provide a scientific basis for the hepatoprotective effects of Antrodia cinnamomea. Data
also imply that antroquinonol, a potent bioactive compound may be responsible for the hepatoprotective activity of Antrodia
cinnamomea. Moreover, the present study highly supported our traditional knowledge that Antrodia cinnamomea as a
potential candidate for the treatment of alcoholic liver diseases.

Abstract: Antrodia cinnamomea is an expensive and highly valued folk medicinal fungus that grows only inside the rotten
trunk of Cinnamomum kanehirae, an evergreen broad-leaved tree. This fungus has recently been used commercially in the
formulation of nutraceuticals and functional foods in Taiwan. It has been used for centuries as a detoxificant in cases of food
poisoning, diarrhea, vomiting, hepatic disease and various kinds of cancers. The present study investigated the effects of
Antrodia cinnamomea on mutagenicity using a bacterial reverse mutation assay employing the Salmonella typhimurium
strains TA97, TA98, TA100, TA102, and TA1535. The effects of Antrodia cinnamomea on chromosome structure were
tested in Chinese hamster ovary (CHO) cells. Antrodia cinnamomea was not mutagenic in all bacterial strains and it was not
genotoxic in CHO cells.

Abstract: Antrodia cinnamomea is a precious edible fungus endemic to Taiwan that has long been used as a folk remedy for
health promotion and for treating various diseases. In this study, an index of 13 representative metabolites from the ethanol
extract of A. cinnamomea fruiting body was established for use in quality evaluation. Most of the index compounds selected,
particularly the ergostane-type triterpenoids and polyacetylenes, possess good anti-inflammation activity. A comparison of
the metabolite profiles of different ethanol extracts from A. cinnamomea strains showed silmilar metabolites when the
strains were grown on the original host wood (Cinnamomum kanehirai) and harvested after the same culture time period (9
months). Furthermore, the amounts of typical ergostane-type triterpenoids in A. cinnamomea increased with culture age.
Culture substrates also influenced metabolite synthesis; with the same culture age, A. cinnamomea grown on the original
host wood produced a richer array of metabolites than A. cinnamomea cultured on other wood species. We conclude that
analysis of a fixed group of compounds including triterpenoids, benzolics, and polyacetylenes constitutes a suitable, reliable
system to evaluate the quality of ethanol extract from A. cinnamomea fruiting bodies. The evaluation system established in
this study may provide a platform for analysis of the products of A. cinnamomea.

The in vitro anti-inflammatory activity of methanol extract of liquid cultured mycelia of Antrodia cinnamomea (MEMAC)
was judged by the measurement of the produced levels of pro-inflammatory cytokines and mediators in lipopolysaccharide
(LPS)-stimulated RAW264.7 cells and human peripheral blood mononuclear cells (PBMCs). The in vivo anti-inflammatory
activity of MEMAC was evaluated using carrageenan-induced hind paw edema in mice, the activities of catalase (CAT),
superoxide dismutase (SOD), and glutathione peroxidase (GPx) in the liver and the levels of malondialdehyde (MDA) and
nitrite oxide (NO) in the edema paw. The levels of serum NO and TNF-α were measured. The MEMAC was administered at
15
the concentrations of 100, 200, and 400mg/kg body weight of mouse.
RESULTS: MEMAC inhibited the production of LPS-induced pro-inflammatory cytokines (TNF-α and IL-6) and
mediators (NO and PGE2) in RAW264.7 cells and human PBMCs. Data from Western blotting showed that MEMAC
decreased the levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) protein expression in
LPS-stimulated RAW264.7 macrophages. In vivo, MEMAC showed significant (p<0.05) anti-inflammatory activity by
reducing the edema volume in carrageenan-induced paw edema in mice. MEMAC (400mg/kg) also reduced the
carrageenan-induced leukocyte migration (50.92±5.71%). Further, MEMAC increased the activities of CAT, SOD, and GPx
in the liver tissue and decreased the levels of serum NO and TNF-α after carrageenan administration.
CONCLUSIONS: Our results showed that MEMAC has the anti-inflammatory property both in vitro and in vivo,
suggesting that it may be a potential preventive or therapeutic candidate for the treatment of inflammatory disorders.

34. 4-Acetylantroquinonol B Isolated from Antrodia cinnamomea Arrests Proliferation of Human Hepatocellular

Abstract: The 4-acetylantroquinonol B isolated from the mycelium of Antrodia cinnamomea could inhibit proliferation of
hepatocellular carcinoma cells HepG2 with IC (50) 0.1 µg/mL. When the HepG2 cells were treated with
4-acetylantroquinonol B for 72 h, the proportion of cells in the G1 phase of the cell cycle increased and that in the S phase
decreased significantly, and the proportion of G2/M phase cells were not obviously changed. In addition, the
4-acetylantroquinonol B treatment resulted in the decreases of CDK2 and CDK4, and an increase of p27 in a
dose-dependent manner. The protein levels of p53 and p21 proteins were also increased when the cells were treated with
low dosage (0.1 µg/mL) of 4-acetylantroquinonol B. Higher dosages, however, decreased the expression of p53 and p21
proteins. Assay of RT-PCR indicated that, corresponding to the increases of p53 and p21 proteins at the dosage of 0.1
µg/mL, the mRNAs of p53 and p21 showed 1.66- and 1.61-fold upregulations, respectively. Corresponding to the decreases
of CDK2 and CDK4 proteins, the mRNAs of CDK2 and CDK4 showed -1.02- and -1.13-fold downregulations, respectively.
However, level of p27 mRNA showed -1.2-fold downregulation in spite of the increase in p27 protein. This observation,
again, confirms the fact that the p27 gene rarely undergoes homozygous inactivation in cancer cells. Our finding suggested
that the 4-acetylantroquinonol B inhibits proliferation of HepG2 cells via affecting p53, p21 and p27 proteins, and can be
considered as a potential cancer drug.

Abstract: Antrodia cinnamomea is a Taiwanese medicinal mushroom with high antioxidant and polysaccharide content.
The objective of this study is to investigate developmental toxicity of A. cinnamomea in pregnant Sprague-Dawley rats.
Animals were daily gavaged with A. cinnamomea mycelium at dosage levels of 0 (reverse osmosis water), 50, 150, and 500
mg/kg from gestation day (GD) 6 to 15. All dams were sacrificed on GD 20 and were subjected to cesarean section. Fetuses
were examined for external, visceral, and skeletal abnormalities. All copulated females survived until the end of the study.
No significant differences were recorded in body weight change, food consumption, and maternal gestational parameters.
Only two fetal malformations were noted in 970 fetuses from the treatment groups. Some variations, such as enlarged
fontanel, split sternebrae, absent sacral, absent caudal vertebral centra, absent thoracic centra, absent 13th-14th ribs, and
fused ribs, were found during the skeletal examination, but no treatment-induced abnormalities occurred. No dose
dependency was observed in any of the developmental variations. Overall observation of foetal malformations from rats
given A. cinnamomea mycelium during pregnancy demonstrates that this material is not teratogenic at doses up to 500
mg/kg. It is concluded that A. cinnamomea BCRC 35398 mycelium has no teratogenic effects in female rats and is safe to
16
be used as a functional food ingredient.

Abstract: Medicinal mushroom Antrodia cinnamomea is a higher Basidiomycetes endemic to Taiwan, where it is
commonly used as a traditional folk medicine. It is well known for its multiple biologic activities and its potential for
commercial development. Here, ten full lengths of cytochrome P450 (CYP) genes (ac-1 to ac-10) from A. cinnamomea
were cloned and identified. With the exception of ac-3 and ac-8, which will probably be assigned as new CYP families,
these genes had more than 40% amino acid identity and close evolutionary relationships to known CYPs. Among the ten
genes, only Ac-7 did not possess a transmembrane domain but had an N-terminal signal peptide, so it was considered a
novel extracellular CYP. The ten A. cinnamomea CYPs had different expression profiles in different growth conditions. In
general, they were strongly expressed during the formation of fruiting bodies, especially in natural basidiomycetes. The
expression of six CYPs of A. cinnamomea (ac-1 to ac-3 and ac-5 to ac-7) were strictly inhibited in the mycelia cell type. It
was therefore concluded that these CYPs are most active in the fruiting bodies of A. cinnamomea.

Abstract: Antrodia cinnamomea (named as Niu-chang-chih), a well-known Taiwanese folk medicinal mushroom, has a
spectrum of biological activities, especially with anti-tumor property. This study was carried out for the first time to
examine the potential role and the underlying mechanisms of A. cinnamomea in the differentiation of human leukemia
HL60 cells. We found that the methanol extract of liquid cultured mycelia of A. cinnamomea (MEMAC) inhibited
proliferation and induced G1-phase cell cycle arrest in HL60 cells. MEMAC could induce differentiation of HL60 cells into
the monocytic lineage, as evaluated by the morphological change, nitroblue tetrazolium reduction assay, non-specific
esterase assay, and expression of CD14 and CD11b surface antigens. In addition, MEMAC activated the extracellular
signal-regulated kinase (ERK) pathway and increased CCAAT/enhancer-binding protein β (C/EBPβ) expression. Reverse
transcriptase polymerase chain reaction analysis showed that MEMAC upregulated the expression of C/EBPβ and CD14
mRNA in HL60 cells. DNA affinity precipitation assay and chromatin immunoprecipitation analyses indicated that
MEMAC enhanced the direct binding of C/EBPβ to its response element located at upstream of the CD14 promoter.
Furthermore, inhibiting ERK pathway activation with PD98059 markedly blocked MEMAC-induced HL60 monocytic
differentiation. Consistently, the MEMAC-mediated upregulation of C/EBPβ and CD14 was also suppressed by PD98059.
These findings demonstrate that MEMAC-induced HL60 cell monocytic differentiation is via the activating ERK signaling
pathway, and downstream upregulating the transcription factor C/EBPβ and differentiation marker CD14 gene, suggesting
that MEMAC might be a potential differentiation-inducing agent for treatment of leukemia.

Abstract: Antrodia cinnamomea is peculiar to Taiwan. It only grows on one host and is highly valued as an important
component of several traditional Chinese medicines. In this study, the different protein expression profiles of artificially
cultivated vegetative mycelium and wild-type basidiomatal fruiting bodies were compared and unique protein spots from
wild-type basidiomatal fruiting body were investigated using 2D polyacrylamide gel electrophoresis and LC-MS/MS
protein identification. Most of the wild-type proteins not seen in the artificially cultivated mycelium were associated to
function in metabolism, cell stress, ROS scavenging, and cell growth. Several proteins from wild-type basidiomes, such as
catalase, aryl-alcohol dehydrogenase, S-adenosyl-L-homocysteine hydrolase, intradiol dioxygenase, haloacid
dyhydrogenase, alpha- and beta-form tubulin, prohibitin, septin, chaperone, and HSP90 ATPase, showed higher
expression than those from artificially cultured mycelium at the mRNA level.

Abstract: Antrodia cinnamomea has recently become a well-known medicinal mushroom in Taiwan. Bioactive
compounds found in A. cinnamomea include: polysaccharide, sesquiterpene lactone, steroids and triterpenoids. The aim of
this study was to evaluate the feasibility of adding citrus peel extract to enhance the formation of bioactive metabolites in
the submerged culture of A. cinnamomea. With the exception of grapefruit, citrus peel extracts tested were proved to be
beneficial to mycelial growth and to the production of intracellular polysaccharide. Lemon was the most effective for
enhancing bioactive metabolite production. With an addition of 2% (v/v), the mycelium biomass concentration and
intracellular polysaccharide content rose from 11.96 g DW/L of the control and 123.6 mg/g DW to 21.96 g DW/L and
230.8 mg/g DW, respectively, on day 8. The production of triterpenoids also increased from 86.7 to 282.9 mg/L.
Moreover, this study also demonstrates that although the addition of peel extract could cause the lengthening of the
exponential phase and reduce the specific growth rate, the production rate of biomass, intracellular polysaccharide and
triterpenoids was still enhanced significantly.

Abstract: Cancer metastasis is a primary cause of cancer death. Antrodia cinnamomea (A. cinnamomea), a medicinal
mushroom in Taiwan, has shown antioxidant and anticancer activities. In this study, we first observed that ethanol extract of
fruiting bodies of A. cinnamomea (EEAC) exerted a concentration-dependent inhibitory effect on migration and motility of
the highly metastatic CL1-5 cells in the absence of cytotoxicity. The results of a gelatin zymography assay showed that
A.cinnamomea suppressed the activities of matrix metalloproteinase-(MMP-) 2 and MMP-9 in a concentration-dependent
manner. Western blot results demonstrated that treatment with A. cinnamomea decreased the expression of MMP-9 and
MMP-2; while the expression of the endogenous inhibitors of these proteins, that is, tissue inhibitors of MMP (TIMP-1 and
TIMP-2) increased. Further investigation revealed that A. cinnamomea suppressed the phosphorylation of ERK1/2, p38, and
JNK1/2. A. cinnamomea also suppressed the expressions of PI3K and phosphorylation of Akt. Furthermore, treatment of
CL1-5 cells with inhibitors specific for PI3K (LY 294002), ERK1/2 (PD98059), JNK (SP600125), and p38 MAPK
(SB203580) decreased the expression of MMP-2 and MMP-9. This is the first paper confirming the antimigration activity of
this potentially beneficial mushroom against human lung adenocarcinoma CL1-5 cancer cells.

JNK1/2. A. cinnamomeaalso suppressed the expressions of PI3K and phosphorylation of AKT. This is the first report
confirming the anti-migration activity of this potentially beneficial mushroom against human lung adenocarcinoma CL1-0.

Abstract: Antrodia cinnamomea, a well-known tradition Chinese medicine, possesses anti-tumor, anti-oxidation activities
and stimulates the immune system. The aim of this study was to investigate the protective effect of water-soluble
polysaccharides from the fermented filtrate and mycelia of Antrodia cinnamomea in submerged culture (ACSC) on
hydrogen peroxide-induced cytotoxicity and DNA damage in Chang liver cells. Oxidative DNA damage was evaluated by
single cell gel electrophoresis (Comet assay) or by the formation of 8-hydroxy-deoxyguanosine (8-OHdG) adducts. The
polysaccharides isolated by ion-exchange chromatography contained glucose, xylose, galactose, arabinose, and mannose.
The results showed that incubation of Chang liver cells with isolated polysaccharides at 200 µg/mL for 5 h prior to H2O2
treatment (50 µM, 30 min) significantly reduced oxidative DNA damage as detected by the formation of comet tail DNA
and 8-OhdG adducts by 89% and 69%, respectively. Pre-treatment Chang liver cells with polysaccharides also reduced the
levels of thiobarbituric acid reactive substances (TBARS) (p < 0.01) and intracellular reactive species (ROS) (p < 0.01)
induced by H2O2. Moreover, glutathione S-transferase (GST) and the GSH/GSSG ratio were significantly increased in
Chang liver cells pre-incubated with the polysaccharides (p < 0.01). These results demonstrate that polysaccharides in
ASCS have antioxidant properties which may involve up-regulation of GST activity, maintenance of normal GSH/GSSG
ratio, and scavenging of ROS.

Abstract: The objective of this study was to evaluate the hepatoprotective activity against the ethanol-induced cytotoxicity
by Antrodia cinnamomea which were produced from a large-scale fermentation. The production of biomass, extracellular
polysaccharide (EPS), intracellular polysaccharide (IPS), and triterpenoids was 27.1, 1.2, 0.7, and 2.0 g/L, respectively,
using a 5000-L agitated bioreactor with 3500 L of A. cinnamomea medium (ACM). The hepatoprotective effects of the
water extract from the mycelia of A. cinnamomea (WAC) were evaluated in vitro using ethanol-induced cytotoxicity on
AML12 hepatocytes. The cytotoxicity and the apoptosis-associated phosphatidyl serine redistribution of plasma membrane
to AML12 cells induced by 300 mM ethanol were effectively reduced by adding 500 mg/L of WAC. From the compositional
analysis, the major component in WAC was polysaccharides that showed a high galactose content (70.9 mg/g crude
polysaccharide). Hence, the large-scale fermentation was efficient in producing cell mass and its metabolites which were
able to protect hepatocytes from the damage by ethanol.

Abstract: Effects of carbon sources, nitrogen sources, plants oils and oxygen supply on the cell growth and production of
bioactive metabolites such as exopolysaccharide (EPS), intracellular polysaccharide (IPS) and triterpenoid in the submerged
culture of Antrodia cinnamomea CCRC36716 were studied in detail. Malt extract (ME), yeast extract (YE) and corn steep
powder (CSP) were favorable nitrogen sources to the mycelial growth. The highest cell growth (12.52 ± 0.03 g/l cell dry
weight), EPS production (1861 ± 62 mg/l) and IPS content (41 ± 12 mg/g DW) can be obtained on day 10 of cultivation in the
medium containing 3% CSP, 3% YE, and 3% ME, respectively. The highest overall triterpenoid production (30 mg/g DW)
was obtained in 3% CSP medium after 14 d of cultivation. Amongst five carbon sources examined, maltose and glucose
yielded relatively high mycelial biomass; high cell densities of 8.29 ± 0.05 and 8.69 ± 0.05 g DW cells/l were obtained after
10 d of cultivation when 4% of maltose and glucose was used, respectively. Pronounced production of EPS, 1482 ± 63 and
1318 ± 48 mg/l, was obtained after 10 d of cultivation when 4% of lactose and sucrose was used, respectively. The maximum
IPS content (49 ± 9 mg/g DW) was achieved in 4% glucose medium after 10 d of cultivation; the highest overall triterpenoid
production (31 mg/g DW) was obtained in 2% glucose medium after 14 d of cultivation. All plant oils tested stimulated cell
growth of A. cinnamomea, enhanced the production of IPS, but inhibited the triterpenoid production. EPS production was
slightly inhibited with soy oil but enhanced by the other oils tested, and the maximal EPS production (1147 ± 47 mg/l) was
obtained when 0.5% of peanut oil was supplemented. The high O2 supply in the A. cinnamomea culture was favorable for cell
growth and polysaccharide production, but was inhibitory on the triterpenoid production. The results obtained are useful in
regulation and optimization of A. cinnamomea culture for efficient production of cell mass and bioactive metabolites such as
EPS, IPS and tripterpenoids in the submerged culture.

Abstract: Sulfated polysaccharides (SPSs) of Antrodia cinnamomea were extracted by an exhaustive papain digestion and
characterized, and their biological functions were evaluated. In this study, we demonstrated the existence of SPSs in the
medicinal fungus, A. cinnamomea. Since no SPSs had previously been identified in any fungal organism, we attempted to
characterize those from A. cinnamomea. SPSs from A. cinnamomea inhibited in vitro Matrigel tube formation, in an
angiogenesis model, in a dose-dependent manner. Furthermore, using serum deprivation-induced apoptosis in neuronal-like
PC12 cells as a stress model, the SPSs of A. cinnamomea were effective in preventing serum-deprived apoptosis.
Compositional analysis revealed that myo-inositol, fucose, galactose, and glucose were the neutral sugars in SPSs of A.
cinnamomea, and these SPSs had a high sulfate content. The sulfation degree paralleled their antiangiogenic and
neuroprotective activities. In this work, we report novel data on the structure, antiangiogenic, and neuroprotective effects of
these fungal SPSs.

Abstract: Antrodia cinnamomea Chang & Chou, sp. nov. growing rarely on the inner wall of Cinnamomum kanehirai Hay
was identified as a new species of Antrodia, which is an expensive folk medicine and used as an antidote, anticancer and
anticnesmatic drug. In this study the influence of different physical and chemical factors on the growth of mycelium by A.
cinnamomea CCRC35396 was investigated in submerged cultures of using shake flasks. In addition, response surface
methodology (RSM) was also used to optimize medium composition for the enhancement of biomass productivity.
The results indicate that when a submerged culture in shake flasks was operated at 25 °C, initial pH 5 and rotation speed
21
100 rpm, the mycelium concentration reached 486.8 mg/100 ml at 14th day. High rotation speed was unfavorable to the
growth of mycelium and the optimum was around 100 rpm. According to the RSM, optimal initial pH and the concentrations
of C-source and N-source were determined and the mycelium concentration of A. cinnamomea rose to 2164.2 mg/100 ml at
the 7th day and the biomass productivity had a eightfold increase, compared to the growth in basal medium. The results
proved that the growth rate of mycelium of A. cinnamomea could be highly enhanced by means of the control of cultural
conditions and the modification of medium compositions based on the RSM.

Abstract: Extracellular lipase from Antrodia cinnamomea BCRC 35396 was first purified by ammonium sulphate
precipitation and DEAE-Sepharose chromatography. The yield and purification factor were 33.7% and 17.2 folds,
respectively. Lipase production from A. cinnamomea was enhanced by 0.01% olive oil supplementation as additional carbon
source in an aerated bioreactor with final titer 26 U/ml after 18 days of fermentation. The molecular weight of the purified
enzyme was estimated to be 60 kDa by SDS-PAGE. The enzyme was found to be alkaline tolerant (pH 7–10) with optimum
activity at pH 8.0, but both activity and stability decreased significantly as pH value greater than 10. The enzyme activity
was clarified to be stable within the temperature range of 25–60 °C, with maximal activity at 45 °C. This observation was
similar to those of mesophiles as expected.

Abstract: This paper describes a study of the extracellular lipase synthesised by a submerged culture of Antrodia cinnamomea
in two different media (modified ME and modified YM). Lipase production increased substantially upon the addition of
glucose; when it comprised 8% of the modified ME and YM media, the lipase production increased remarkably from 0 to
3.35 mU/ml and from 0.59 to 6.17 mU/ml, respectively. The lipase activity decreased, however, beyond certain
concentrations of glucose. The lipase synthesis in the modified YM medium was superior to that which occurred in the
22
modified ME medium. In addition, the optimum values of pH and temperature for the crude lipase were 11.0 and 60 °C,
respectively. The enzyme was stable at values of pH between 7.0 and 12.0 and at temperatures up to 80 °C. Thus, this novel
lipase from A. cinnamomea is particularly alkaline-resistant and thermostable.

Abstract: Antrodiacinnamomea is a valuable polyporaceous edible fungus native to Taiwan. It was reported to provide a
number of pharmaceutical benefits. A. cinnamomea was cultured, the polysaccharides (PSs) were extracted and
chromatographically fractionated, and their biological functions were evaluated. The PS subfractions (B85PS-I–V) showed
differential inhibition of in vitroMatrigel tube formation (an indicator of angiogenesis inhibition) with IC50 values of 7.44,
16.41, 7.07, 7.98, and 16.33 µg/ml, respectively. Furthermore, A. cinnamomea PSs also blocked vascular endothelial growth
factor (VEGF)-induced endothelial cell migration. B85PS-III and -V dose-dependently decreased angiogenic-related protein
expressions, including inhibition of VEGF receptor (VEGFR) phosphorylation and angiopoietin-2 protein expression. To
further purify and determine the structure of the bioactive PS, B85PS-III was chromatographically purified to give a
water-soluble partial fucosylated 1,6-α-D-mannogalactan (B85PS-III-1) composed of a nonadecasaccharide repeating unit
with a molecular mass of 4.17 × 102 kDa as shown below. The chemical structure of B85PS-III-1 was characterized by a
monosaccharide analysis along with 1H, 13C, and 2D nuclear magnetic resonance spectroscopy.

Abstract: Antrodia camphorata (AC), also known as A. cinnamomea, an endemic species in Taiwan, is one of the treasured
medicinal mushrooms. AC is traditionally used for its chemopreventive biofunctions. In this investigation, we report a
convenient method for concentrating the antiproliferative active triterpenoid-rich fraction (FEA), from ethanolic extract of
AC (EEAC). A series of stereo-isomers of zhankuic acids (1-8) from the FEA was purified by HPLC using an efficient
acidic solvent system. The structures of compounds 1-8 were elucidated based on spectroscopic data analysis, and the
absolute configuration of α-chiral carboxylic acid at C-25 in the structures was assigned based on reaction with (R)- and
(S)-1-(9-anthryl)-2,2,2-trifluoroethanol. Major ingredients of FEA (eight ergostanes 1-8 and two lanostanes 9-10) were
further characterised by high-performance liquid chromatography-photodiode array detection/mass spectrometry
(HPLC-PDA/MS). Compounds 1-8 and their pair mixture forms (antcin K, antcin C, zhankuic acid C, and zhankuic acid A)
were subjected to anti-proliferative assay against three human leukemia cell lines. Among them, the derivatives with
carbonyl group at C-3 showed cytotoxicity with IC50 values ranging from 16.44 to 77.04 µg/ml.

Abstract: In this work a headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography–mass
spectrometry (GC–MS) and GC–olfactometry (GC–O) was developed to evaluate the profile of the volatile compounds that
contribute to the aroma of Antrodia camphorata in submerged culture. For this purpose, the HS-SPME sampling method for
the volatile compounds of A. camphorata in submerged culture was optimised by a D-optimal design. A HS extraction of
the culture broth of A. camphorata followed by incubation on a carboxen/polydimethylsiloxane (CAR/PDMS) fibre during
31.8 min at 54.6 °C gave the most effective and accurate extraction of the volatile compounds. By the optimised method, a
total of 49 volatile compounds were identified in culture broth of A. camphorata, while a total of 55 volatile compounds
were identified in the mycelia. A series of C8aliphatic compounds (mushroom-like odour), several lactones (fruity odour)
and L-linalool (citrus-like odour) were the most potent key odourant in both the mycelia and culture broth. This combined
technique is fast, simple, sensitive, inexpensive and useful to monitor volatile compounds associated to A. camphorata.
Research highlights
► Volatiles of fermented Antrodia camphorata were analysed by HS-SPME–GC–MS. ► Aroma of fermented A.
camphorata was evaluated by HS-SPME–GC–O. ► HS-SPME condition for the volatiles was extensively optimised by a
D-optimal design.

Abstract: A selective and sensitive liquid chromatography–tandem mass spectrometry (LC–MS/MS) method was
developed and validated for the determination of antrodin B and antrodin C in rat plasma. Both target compounds, together
with the internal standard (diazepam), were extracted from rat plasma samples by liquid–liquid extraction with ethyl acetate.

Chromatographic separation was carried out on an Agilent XDB-C8 column with an isocratic mobile phase consisting of
acetonitrile and water (70:30,V/V) at a flow rate of 0.5 mL/min. The mass spectrometric detection was performed by
selected reaction monitoring (SRM) mode via atmospheric pressure chemical ionization (APCI) source operating in positive
ionization mode. The assay exhibited a linear dynamic range of 47.6–4760 ng/mL for antrodin B and 56.6–5660 ng/mL for
antrodin C. The intra- and inter-day precision was less than 5.3% and the accuracy was less than 2.7% for both analytes.
The validated method has been applied to the pharmacokinetic study of antrodin B and antrodin C in rats following oral
administration of Antrodia camphorata extract.
