• Evolution of CRISPR towards accurate and efficient mammal genome engineering

    Small molecules enhance knock-in efficiency. (A) Small molecules related to the NHEJ or HDR repair pathway. Inhibitors are labeled in red, activators are labeled in blue. NU7026 inhibits DNA-PK, and SCR7, E1B55K, and E4orf6 inhibit DNA ligase IV. MLN4924, NSC15520, RS-1, Trichostatin A, or Resveratrol enhance CtIP, RPA, RAD51, or ATM, respectively. ATM protein also induces activation of RPA, BRCA2, and RAD51. The i53 is an inhibitor of 53BP1. The i53 activates DNA end resection and recruitment, of BRCA1 to DSBs. (B) HDR activity is increased at S/G2 phase. NHEJ activity is labeled in blue, HDR activity is labeled in red. Small molecules are used to arrest the cell cycle at specific phase, to improve HDR efficiency. L755505, Resveratrol, Mimosine, Aphidicolin, Thymidine and Hydroxyurea block cells at the G1 to S phase before DNA replication, and Nocodazole arrests cell cycle at G2/M phase. Lovastatin also inhibits at early G1, and partially at G2/M phase.
  • Stem cells and reproduction

    Current applicable assisted reproductive technologies for mitochondrial replacement. From an MII oocyte with mutated mtDNA, spindle or PB1 is isolated and transferred to an enucleated MII oocyte with healthy mtDNA. Reconstructed oocytes by ST or PB1T are fertilized with sperm. In the zygote with mutated mtDNA, PNs or PB2 can be transferred to enucleated zygotes with healthy mtDNA. Two PNs are enucleated for PNT while only one PN is for PB2T. For SCNT, the fibroblasts carrying mutant mtDNA are transferred to enucleated MII oocytes with healthy mtDNA. Reconstructed SCNT oocytes are activated artificially. Embryos with healthy mtDNA can develop into ESCs or offspring. MII, metaphase II; mtDNA, mitochondrial DNA; ST, spindle transfer; PB1T, 1st polar body transfer; PB2T, 2nd polar body transfer; PNT, pronucleus transfer; SCNT, somatic cell nuclear transfer; ESCs, embryonic stem cells.
