Knockout/Knock In/Transgenic Animals

Why we care about that?

- Knockout/Knock-In animal (mouse) : Disease Model For Medical Research

- Immune-deficient Pig : Xenotransplantation?

- Transgenic Animals : Animal Bioreactor?

Production of useful protein in Milk or Egg?

- Domestic Animal Breeding?

Knockout Mouse

Knockdown vs KnockoutGene Knockdown

- Expression level of mRNA was decreased by RNAi (siRNA/shRNA/dsRNA)- Gene itself are still intact- SilencingEfficiency is not ~100%- Sometime residual activities are sufficient for phenotypes- Relatively easy and fast to perform- You can do in embryonic lethal gene

Gene Knockout

- Gene locus in chromosome is permanently removed/changed

- Complete loss of genotype- Difficulty & Time consuming- Embryonic lethal gene : Conditional Knockout

Knockout mouse from Embryonic Stem Cell

Homologous Recombinantion

BAC recombineering

BAC : Bacterial Artificial Chromosome

Plasmid vector can have ~150kb of insertUsed for the Original Human Genome ProjectsIdeal for modification of Large fragments for the homologus recombinantion

Most of

Conditional Knockout

- Cre recombinase

- Why we need to make conditional knockout mouse ?

Embryonic Lethal

Oocyte Specific Knockout

- Cre recombinase are expressed in oocyte by ZP3 promoter- Desired locus has modified to have LoxP

Knock inTransgenic vs Knock-In?

Transgenic Animals

- Embryonic Stem Cell

- Somatic Nuclear Transfer

- Viral Vector

Novel strategy for generation of knockout/knock-in/transgenic

- Zinc-Finger Nuclease- TALEN- CRISPER

Genome Engineering?

Zinc-Finger Nuclease

TALEN

CRISPR

One-step generation of Knockout Animal using TALEN
