TGFB1 and Hepatic fibrosis: The results showed that PE supplementation in LX-2 cells significantly reduced TGFβ1-induced production of fibrosis proteins (i.e., collagen 1α1, platelet-derived growth factor receptor (PDGFR)α, and PDGFRβ) (Fig. 6B), suggesting that PE supplementation could rescue liver fibrosis caused by TGFβ1 stimulation.
