Unfortunately, current clinical treatment options offer limited efficacy, highlighting the necessity for uncovering novel therapeutic strategies. Here, monotherapy and combination library screening were employed, and identified that the efficacy of obatoclax, a pan-Bcl-2 family inhibitor, was improved significantly when combined with ER-stress inducers, including tunicamycin. Combinatorial knockdown of anti-apoptotic proteins confirmed that the loss of Mcl-1 and Bcl-xL synergistically enhanced apoptosis under ER stress conditions. Although ER stress inducers triggered the stress response in GBM cells, obatoclax co-treatment enhanced this response by upregulating ATF-4 and CHOP, which promoted apoptosis along with increased caspase 3/7 activity and cleavage of PARP. ATF-4 knockdown significantly decreased the apoptosis induced by obatoclax and tunicamycin co-treatment and reduced the expression of CHOP and BIM. Under ER stress responses, GBM cells exerted an autophagy response to recover from the stress condition; however, obatoclax co-treatment disrupted the autophagy responses, particularly by disrupting autophagic cargo degradation.
