Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis in tumor cells but faces limitations due to resistance mechanisms involving anti-apoptotic regulators such as Bcl-2. This study investigates Tasisulam, a molecular glue degrader, that degrades RNA-binding motif protein 39 (RBM39), as a sensitizer for TRAIL-mediated apoptosis in renal cell carcinoma (RCC). Tasisulam enhances TRAIL-induced apoptosis by activating both extrinsic and intrinsic apoptotic pathways, achieved through upregulation of death receptor 5 (DR5) and downregulation of B-cell lymphoma 2 (Bcl-2).
