primary cells. Glucose-mediated decreases in protein kinase G-I levels are inhibited by superoxide scavenger tempol or NAD(P)H oxidase inhibitors diphenylene iodonium or apocynin. High glucose exposure time-dependently increases superoxide production, which is abolished by tempol or apocynin treatment, but not by L-NAME, rotenone, or oxypurinol.Total protein levels and phosphorylated levels of subunit p47phox are increased after high glucose exposure. Transfection of cells with siRNA-p47phox abolishes glucose-induced superoxide production and restores protein kinase G-I protein levels |
