RSV reversed HK-2 cell EMT induced by AAs and TGF-β. a. Western blotting results of E-cadherin, α-SMA, and COL1A1 in HK-2 cells 48 h following the treatment of AAs (10 μmol/L)/TGF-β (10 ng/mL) with or without the presence of RSV (20 μmol/L). b. Real-time PCR results of E-cadherin, α-SMA, and COL1A1 in HK-2 cells 48 h following the treatment of AAs (10 μmol/L) with or without the presence of RSV (20 μmol/L). c. Real-time PCR results of E-cadherin, α-SMA, and COL1A1 in HK-2 cells 48 h following the treatment of TGF-β (10 ng/mL) with or without the presence of RSV (20 μmol/L). d. RSV reversed HK-2 cell EMT by inhibiting the translocation of β-catenin into the nuclear. e. Immunofluorescence staining of β-catenin in HK-2 cells 48 h following the treatment of AAs with or without the presence of RSV (*P < 0.05 AAs vs. AAs + RSV, **P < 0.01 AAs vs. AAs + RSV).
