Abstract:The microtubule protein, βIII-tubulin, has been implicated as a prognostic, pro-survival, and chemoresistance factor in some of the most lethal malignancies including pancreatic ductal adenocarcinoma (PDAC). However, precise survival mechanisms controlled by βIII-tubulin in cancer cells are unknown. Here, we report an unexpected role of βIII-tubulin as a brake on extrinsic caspase 8-dependent apoptosis in PDAC. We show that βΙΙΙ-tubulin knockdown frees death-receptor DR5 to increase its membrane diffusion, clu… Show more
