NO donor decreased IRS-2 protein expression in β-cells. GSNO (300 μm) decreased IRS-2 protein expression in a time-dependent manner in INS-1/832 cells (A). 5-h treatment with GSNO exerted dose-dependent inhibitory effects on IRS-2 expression in INS-1/832 cells (B) and βTC-6 cells (D). Treatment with SNAP (300 μm) for 5 h also resulted in suppressed expression of IRS-2 in INS-1/832 cells (C). IB, immunoblotting. *, p < 0.05; **, p < 0.01; ***, p < 0.001 versus the cells without NO donor. Error bars, S.E.
