YAP1 and Peritoneal Fibrosis: PDF containing glucose at supraphysiologic concentrations and glucose degradation products such as methylglyoxal, as well as an acidic pH, promoted YAP expression and nuclear translocation, activated the FMT, increased the population of myofibroblasts and the levels of myofibroblast‐produced collagen 1, and led to peritoneal fibrosis.
