FGF2 and pulmonary fibrosis: 2019). Jiang et al. (2020) demonstrated that SAB could delay the progression of pulmonary fibrosis through inhibiting inflammatory response and regulating the fibrosis pathway. Moreover, several in vitro and in vivo studies implied that SAB was protective for renal tubular cells and interstitial cell. Hu et al. (2020) showed that SAB at a dose of 6.25 mg/kg decreased TGF-β and FGF-2 level and alleviated ECM components in the kidney of UUO mice model.
