There was also a study characterizing the interaction of gastric cancer with peritoneal fibrosis which determined that TGF-b1 plays a key role in induction of peritoneal fibrosis, resulting from collagen formation and deposition, which in turn affected gastric cancer adhesion and metastasis in vitro and in vivo (27). The gene discussed is TGFB1; the disease is Peritoneal Fibrosis.
