InCeT-TLZ induces DNA damage and cell death in BRCA1-deficient tumor cells. (A) BRCA-deficient cancer cells (W780 and W0069) were treated with 2 or 4 mm InCeT-TLZ for 48 h. Biomarkers of DNA damage (γH2AX), cell death (cleaved (c)-caspase 3 and cleaved-PARP) and cell cycle arrest (cyclin D1) were detected by western blotting. W780 (B) and W0069 (C) were treated with a 1 mm empty spacer or InCeT-TLZ for 5 days. Cell viability was detected using the MTT assay. Results were normalized to the DMSO control. Data was shown as mean ± SD. ***p < 0.001 vs. DMSO control.
