Sun et al. (pulmonary fibrosis), Han et al. (NASH), and Tang et al. (mesangial cell) showed that MaR1 ameliorates pulmonary fibrosis by inhibiting TGF-β1, cell migration, fibroblast differentiation and collagen expression [58,62,63]. This evidence concerns the gene TGFB1 and metabolic dysfunction-associated steatohepatitis.
