Fig. 6: USP14 promotes VSMC proliferation in a Skp2-dependent manner.

A, B Cells were treated with IU1/USP14 siRNA or/and PDGF-BB, followed by flow cytometry. C Cell number at various phases. D, E Western blot assay was performed to measure the expression of Skp2, p27, and USP14. GAPDH was used as the loading control.
