TMZ exposure induces selective vulnerability to BCL-XL inhibitors. GBM76 and GBM39 were treated with TMZ (100 µmol/L) for 7days followed by 14 days of TMZ-free media prior to treatment with BCL-2 family inhibitors as shown. TMZ-treated cells demonstrated selective vulnerability to BCL-XL inhibitors (A1331852, A1155463, navitoclax), but not to the BCL-2–specific inhibitor (venetoclax). For all experiments, luminescence values are normalized individually to 0 nmol/L control. All data are means ± SD of three technical replicates at each concentration.
