Figure 6. NICD blocked the inhibition of proliferation and metastasis induced by G9a in human melanoma cells. (A) the proliferation of M14 cells with G9a knockdown or both G9a knockdown and NICD treatment was detected by CCK8. (B) the proliferation of A375 cells with G9a knockdown or both G9a knockdown and NICD treatment was detected by CCK8. (C) the migration and invasion of M14 cells with G9a knockdown or both G9a knockdown and NICD treatment was detected by transwell. (D) the column diagram showed the migration and invasion cell number in M14 cells. (E) the migration and invasion of A375 cells with G9a knockdown or both G9a knockdown and NICD treatment was detected by transwell. (F) the column diagram showed the migration and invasion cell number in A375 cells. **P<0.01 vs. Con group; #P<0.05 vs. si-G9a group.
