TGFB1 and metastasis: Biopsies from (i) parietal peritoneum of patients undergoing PD46, PA development after abdominal surgery, or (iii) ovarian carcinoma peritoneal metastasis, were analyzed for the expression of markers related to mechanotransduction pathways (Hippo-YAP/TAZ and CAV1), as well as to TGF-β1 pathway as compared to healthy peritoneum samples.
