Soybean SePPs can attenuate liver fibrosis [125], and liver fibrosis in mice induced by tetrachloromethane (CCl4) was found to be significantly reduced by inhibiting α-smooth muscle actin synthesis, promoting GSH-Px synthesis, and increasing mRNA expression of matrix metalloproteinase 9 in liver tissue [98]. The gene discussed is MMP9; the disease is Hepatic fibrosis.
