Web7 apr. 2024 · Perurena et al. show that PDACs are resistant to MEK inhibitors because they trigger the formation of USP9X:Mcl-1 complexes, thereby acutely stabilizing Mcl-1 and inhibiting apoptosis. Resistance can be overcome by targeting Mcl-1 with direct inhibitors or by suppressing Mcl-1 transcription with CDK inhibitors, revealing new therapeutic … WebExposing hTERT-HPNE cells to sodium butyrate and 5-aza-2'-deoxycytidine lead to the formation of pancreatic ductal cells marked by the expression of MDR-1, carbonic anhydrase II, and the cytokeratins 7, 8, and 19. hTERT-HPNE cells were found to have properties of the intermediary cells formed during acinar-to-ductal metaplasia, which included …
