Given that we noted a cell death with features of apoptosis induced by the combination treatment, we evaluated the expression of the anti-apoptotic Bcl-2 family members, Bcl-2, Bcl-xL and Mcl-1 in established and PDX GBM cells by utilizing protein capillary electrophoresis and standard western blotting. Here, BCL2L1 is linked to glioblastoma.
