Long-term exposure of kisspeptin decreases (pro)insulin protein level and activates autophagy in NIT-1 cells. Representative blots (a) and mRNA levels of insulin (c) in NIT-1 cells after transfecting pcDNA3.1 + mKiss1-T2A-GFP for 72 h. Quantifications of blots and mRNA normalized by β-actin or RPL19 are shown as the means ± standard errors of the mean (n = 3). (b) Representative blots of autophagy flux marker in cultured NIT-1 cells after overexpressing Kiss1 with/without treating with bafilomycin A1 (20 nM, 3 h). Quantifications of LC3-II normalized by β-actin are shown as the means ± standard errors of the mean (n = 3), which represents autophagy flux. *Compared with level of the control; *p < 0.05; #Compared with autophagy flux of the control; #p < 0.05. The full-length blots are presented in Supplementary Fig. S2.
