SIRT7 suppresses EMT in OSCC cells through deacetylating SMAD4. (a) The results of western blot analysis and its quantitative analysis of the effects of SIRT7 on SMAD4 and Ac-SMAD4 protein expression in HSC3 and OECM1 cells. (b) The results of immunofluorescence staining and its quantitative analysis of the effects of SIRT7 on Ac-SMAD4 protein expression in HSC3 and OECM1 cells. (c) The results of western blot analysis and its quantitative analysis of the effects of SIRT7 on SMAD4, Ac-SMAD4 and EMT markers protein expression in HSC3 cells. (d) The results of western blot analysis and its quantitative analysis of the effects of SIRT7 on SMAD4, Ac-SMAD4 and EMT markers protein expression in OECM1 cells. OE: overexpression; Sh: shRNA that used for SIRT7 knockdown; NC: negative control. * P < 0.05 when compared with group OE-NC; # P < 0.05 when compared with group siR NC groups
