(F) GOMED-mediated degradation of (pro) insulin by glucose deprivation of Atg5 KO MIN6 cells. Atg5 KO MIN6 cells were incubated in glucose-depleted medium in the absence or presence of bafilomycin A1 (10 nM) for the indicated times. The cell lysates were then subjected to immunoblot analysis using an anti-(pro) insulin antibody.
