Valproic Acid Downregulates the Expression of MGMT and Sensitizes Temozolomide-Resistant Glioma Cells

Figure 4

Induction of apoptotic and autophagic cell death in TMZ-resistant glioma cells by VPA and TMZ combination. T98 and U138 cells were untreated or treated with VPA, TMZ, or their combination. (a) The expression of MGMT, Bcl-2, Bak, and caspase-3 was evaluated using western blotting. (b) Conversion of LC3-I to LC3-II was also determined by western blotting. β-actin was used as a loading control. The results are representative of three independent experiments.
