MTOR and pulmonary fibrosis: The Nrf2 signaling pathway [55], mTOR signaling pathway [56], TGF-β1 signaling pathway [57], and NF-κB signaling pathway [56] may be interfered by Rg1, and target myocardial cells, podocytes, thereby preventing renal fibrosis [55], nerve ischemia perfusion injury [56], and lung fibrosis [57].
