The Nampt inhibitor, FK866, decreases lysosomal acidification and suppresses autolysosome function.Figure 5(A) WT MEFs were stained with dextran-Oregon Green and dextran-TMRM to examine lysosomal acidification after 10 nM FK866 treatment. FK866 decreased lysosomal acidification, which was rescued by 1 mM NMN pretreatment. The stained MEFs were quantified using a microscope (BZ-X800, KEYENCE). Error bars are presented as mean ± SEM of three independent experiments. Statistical significance was assessed by one-way ANOVA, ***p < 0.001. (B) LysoSensorTM Yellow/Blue DND-160 was used to detect lysosomal pH function in WT MEFs. Lysosomal acidification was decreased by 10 nM FK866 and rescued by 1 mM NMN. Error bars are presented as mean ± SEM of three independent experiments. Statistical significance was assessed by one-way ANOVA, **p < 0.01. (C) Lysosomal proteolytic capacity was decreased in FK866-treated WT MEFs. DQ-BSA is bovine serum albumin labeled with a green fluorophore. It is taken up by endocytosis and delivered to the lysosomes. As a monomer, the fluorophore is too concentrated and the signal is quenched. Because DQ-BSA is degraded by the lysosomal proteases, it releases monomers, which emit fluorescence. The rate of DQ-BSA hydrolysis (increase in fluorescence units per cell) is a function of lysosomal proteases and was measured using a plate reader over 1 h. The linear range was used to determine the rate. The mean ± SEM rate for each condition is presented in the plot. These values are of a representative experiment. Three independent experiments were performed. Statistical significance was assessed by one-way ANOVA, ***p < 0.001. (D) Lysosomal proteolytic capacity was decreased after 1 mM CAP treatment of WT MEFs in a time-dependent manner, as shown by DQ-BSA. Error bars are presented as mean ± SEM of three independent experiments. Statistical significance was assessed by one-way ANOVA, **p < 0.01, ***p < 0.001. (E) To examine autolysosome formation, we performed immunofluorescence with Lamp2 and p62 antibodies. Lamp2 and p62 were co-localized after 10 nM FK866 or 50 nM bafilomycin A treatment in WT MEF cells. Scale bars, 10 µm. Quantification is shown on the right. Error bars are presented as mean ± SEM of three independent experiments. Statistical significance was assessed by one-way ANOVA, ***p < 0.001. (F) To examine autophagosome and autolysosome formation, we used DAPRed, which indicates autophagosomes, and DALGreen, which indicates autolysosomes. After starvation, co-localization of both staining agents was observed upon FK866 or bafilomycin A treatment in WT MEF cells. Scale bars, 10 µm. Quantification is shown on the right. Error bars are presented as mean ± SEM of three independent experiments. Statistical significance was assessed by one-way ANOVA, ***p < 0.001.
