4、 的效率 12。IC50 & Target DNA Ligase IV CRISPR/Cas9体外研究 SCR7 inhibits joining of double-strand breaks (DSBs) in cell-free repair system. SCR7 blocks Ligase IV-mediated joining by interfering with its DNA binding but not that of T4 DNA Ligase or Ligase I. SCR7 inhibitsNHEJ in a Ligase IV-dependent manner

5、 within cells, and activates the intrinsic apoptotic pathway. Resultsshow a dose-dependent decrease in cell proliferation of MCF7, A549, and HeLa with an IC50 of 40, 34, and 44M, respectively, which is further confirmed by DIC imaging in MCF7. T47D, A2780, and HT1080 are alsosensitive to SCR7, with

Untreatedtumor animals survived only for 52 days, whereas treated animals exhibit 4-fold increase in lifespan 1.PROTOCOLCell Assay 3 Wild-type, AAVS1TLR

7、HEK293 and mouse NIH3T3 cells are maintained in DMEM supplied with 15% FBS,cells are passaged three times per week.

10、only.Animal Mice 1Administration 1 BALB/c mice are injected with DLA cells (0.25106) intraperitoneally for tumor development, after which twobatches of animals are divided into eight subgroups. Treatment is started after 5 days of DLA injection (d 0).Group I serves as tumor control (n=10). Group II

11、(IR, n=5) and III (IR+SCR7, n=5) receive two doses ofradiation (2 Gy) on day 0 and 4. Besides radiation, Group III also receives six doses of SCR7 (20 mg/kg) onalternate days from day 0. Group IV (Etoposide, n=5) and V (Etoposide+SCR7, n=5) received three doses ofEtoposide (10 mg/kg) intraperitoneal

Group VI (3-ABA, n=5) and VII (3-ABA+SCR7, n=5) received three doses of 3-Aminobenzamide (10 mg/kg) on days 0, 4, and 8. Group VIIreceives six doses of SCR7. Group

13、VIII (SCR7, n=5) receives six doses of SCR7 alone (20 mg/kg) onalternate days (0, 2, 4, 6, 8, and 10) and serves as the control.
