TGFB1 and Peritoneal Fibrosis: Of note, it prevents and ameliorates peritoneal fibrosis in a mouse model of peritoneal fibrosis and in TGFβ1-treated peritoneal mesothelial cells as illustrated by our previous study [27]; and (3) we present compelling evidence that BRG1 is a pro-fibrotic regulator during peritoneal fibrosis, yet MCL binds to BRG1, thereby inhibiting BRG1-induced peritoneal fibrosis.
