Figure Lengend Snippet: Fig. 6. CCT128930 enhanced the anticancer effect of VS5584 in human osteosarcoma cells. (A) Combined inhibitory effect of CCT128930 and VS5584 on U2OS cells. U2OS cells were co-treated with 5 μM CCT128930 or/and 5 μM VS5584 for 24 h. Cell inhibitory rate was detected by CCK-8 assay. (B) CCT128930 enhanced VS5584-induced early apoptosis in human osteosarcoma cells. U2OS cells were exposed to 5 μM CCT128930 or/and 5 μM VS5584 for 24 h. Then, cells were stained by Annexin-V/PI, and examined by a fluorescence microscope. Apoptotic cells were calculated by counting annexin-positive cells. (C) Cells apoptosis imaged by fluorescence microscope. CCT128930 enhanced VS5584-induced PARP cleavage and caspase activation in U2OS (D) and MG-63 (E) cells. U2OS cells or MG-63 cells were exposed to 5 μM CCT128930 or/and 5 μM VS5584 for 24 h. Protein expression was detected through western blotting method. Bars with different letters indicate the statistical significance at P < 0.05.
