  3. 基因研究的主要内容 敲除 表达调控 编辑

  4. CRISPR/Cas9简介

  5. Synthetic Biology简介 Designing and building novel biological systems

  6. CRISPR/Cas9 system in Zhang Lab: CRISPR v2 Zhang's lab is focused on using synthetic biology to develop technologies for genome and epigenome engineering to study neurobiology.

  7. CRISPR/Cas9 system in Zhang Lab: CRISPR v2 tracRNA:crRNA to sgRNA

  8. CRISPR/Cas9 system in Zhang Lab: CRISPR v2

  9. CRISPR/Cas9 system in Zhang Lab: CRISPR v2 5’…(N5)GAGACG…3’ 3’…(N1)CTCTGC… 5’ 5’…CGTCTC(N1)…3’ 3’…GCAGAG(N5)… 5’ BsmB1: 非回文,有方向 剪切位点不在核心区 两个BsmB1位点可以切出不同尾 两个反方向的BsmB1位点可以将酶切位点切除

  10. Take-home tips (1) • Chimeric sgRNA • PAM • Filler • Enzyme (BsmB1) • 2A peptide

  11. CRISPR/Cas9 system in Zhang Lab: SAM系统 Synergistic Activation Mediators

  12. Take-home tips (2) • RNA aptamer fusion • RNA binding protein: RNA • dCas9 • Selection markers

  13. Modified CRISPR/Cas9 system in our lab EF1α NLS NLS dCas9 dCas9-NLS EF1α EZH2 PCP PCP EZH2 PCP-EZH2 U6 sgRNA sgRNA sgRNA-PP7
