Mesenchymal Stem Cells Alleviate Renal Fibrosis and Inhibit Autophagy via Exosome Transfer of miRNA-122a

Figure 3

MSC-derived exosomes mediate miRNA-122a to relieve renal fibrosis in HK-2 cells in response to TGF-β1. (a) TGFBR1, α-SMA, Col1a1, fibronectin, and E-cadherin mRNA levels were measured by qPCR in HK-2 cells. (b) Western blot analysis of TGFBR1, α-SMA, Col1a1, fibronectin, and E-cadherin protein expression in HK-2 cells. Quantitative analysis of TGFBR1, α-SMA, Col1a1, fibronectin, and E-cadherin protein expression is shown on the right ( independent experiments). (c) LC3 II/I, p62, Beclin 1, ATG7, mTOR, p-mTOR, AKT, and p-AKT protein expression was evaluated by western blotting in HK-2 cells, and their quantitative analysis is shown on the right ( independent experiments). The results are expressed as the . Compared with the TGFβ group, , , and . Compared with TGFβ+MSC- (miRNA-NC) exo, ^###, ^##, and ^#.
