The RAD51 inhibitor RI-1 suppresses the proliferation of cervical cancer cells in vitro. (A) HeLa and SiHa cells were treated with either DMSO or 10 µM RAD51 inhibitor RI-1 for 24 h, and the RAD51 protein was measured by western blotting. Cell growth and MTT assays were performed using RI-1- or DMSO-treated HeLa cells (B and C) and RI-1- or DMSO-treated SiHa cells (D and E). The values are presented from independent experiments performed in triplicates as the mean ± SD. *P<0.05, **P<0.01.
