CircSMAD4 regulated BMP7 expression by targeting miR-377-3p. A MiR-377-3p binding to BMP7 3′UTR was predicted by DIANA tools. B The interaction between miR-377-3p and BMP7 was predicted by dual-luciferase reporter assay. C The expression of BMP7 protein in SV40-MES13 cells treated with HG, NG or mannitol was detected by western blot. D The expression of BMP7 protein in SV40-MES13 cells transfected with miR-377-3p or anti-miR-377-3p was measured by western blot. E The expression of BMP7 protein in SV40-MES13 cells transfected with sh-circSMAD4 or sh-circSMAD4 + anti-miR-377-3p was detected by western blot. *P < 0.05
