LOXL2 and pancreatic ductal adenocarcinoma: These results identify the METTL14-YAP1 feedback loop as a core regulator of mechanical memory in pancreatic ductal adenocarcinoma, which drives stromal dysfunction and tumor progression through CD166-LOXL2 axis, and suggest targeting this loop as a potential therapeutic strategy to disrupt mechanical memory and ameliorate stiffness-induced remodeling.
