Effects of combining GS and DOX in cancer cells. (A) Morphology of DOX-induced cell death. (B) Cell viability of the MTT assay. (C) Western blotting of PARP, caspase-3 and bax protein expression in DLD-1 cells in the presence or absence of GS for 24 h. Images were obtained with a 200× objective of the microscope. The assay methods were performed in the same manner as that described for the H9C2 cells.
