Previous studies showed that multiple signaling pathways were involved in the progression of peritoneal fibrosis, including transforming growth factor-β1 (TGF-β1) [10,11], platelet-derived growth factor (PDGF) [7,12], and epidermal growth factor (EGF) pathways [13]. This evidence concerns the gene TGFB1 and Peritoneal Fibrosis.
