To elucidate the effects of the drugs on the apoptotic signalling pathway in glioblastomas, Western Blot analysis was performed to detect the protein expression levels of apoptosis‐related proteins BAX and BCL‐2, and Cleaved caspase‐3 in U87‐MG and U118‐MG cells after 48 h of drug treatment. Here, BAX is linked to glioblastoma.
