TFEB stimulates clearance of enlarged lysosomes and reduces glycogen burden in PD myotubes.Figure 1A. Confocal microscopy image of PD myotubes (cl. 3LE8) infected for 72 h with adenovirus containing TFEB (PD + Ad-TFEB 72 h) shows a dramatic reduction in the number of large LAMP1-positive lysosomes (red) compared to that in untreated (PD) or adenovirus (PD + Ad-null)-treated PD myotubes. WT myotubes are shown on the left panel. Nuclei are stained with Hoechst (blue). TFEB was detected with anti-Flag antibody (green).B. Distribution of lysosomal size differs significantly in Ad-null and Ad-TFEB PD myotubes (p = 6.32 × 10−8; Kolmogorov-Smirnov test). Lysosomal size is expressed as number of pixels representing lysosomal area (LAMP1-positive structures). The median lysosomal size of Ad-TFEB infected myotubes (m = 367.13 pixels, n = 703, range 208-2659) was significantly lower than that of Ad-null infected myotubes (m = 491.16 pixels, n = 1395, range 200-2857; p = 6.5 × 10−12; Wilcoxon rank sum test).

Confocal microscopy images of live non-infected PD myotubes (left) or PD myotubes infected for 72 h with Ad-TFEB (right) show a dramatic reduction in the amount of accumulated glycogen in TFEB-treated cells. The cells were incubated with the fluorescent glucose (2-NBDG; green), extensively washed, and analysed by confocal microscopy. Bar: 10 µm for all panels.

a) Rubicon siRNA treatment of the NIH 3T3 cells led to decreased levels of p62 and LC3 II under both normal and nutrient-starvation conditions.figf3(a) Rubicon siRNA treatment of the NIH 3T3 cells led to decreased levels of p62 and LC3 II under both normal and nutrient-starvation conditions. (b) Overexpression of Rubicon resulted in increased levels of p62 under both normal and nutrient-starved conditions in HEK 293 cells either stably expressing (upper rows) or transiently transfected with (lower rows) Rubicon-EGFP. The control cells were either stably expressing or transiently transfected with the EGFP-N3 vector. (c) Vps34 kinase activity. HEK 293T cells were co-transfected with Myc-Vps34-Vps15 and Flag-Rubicon or Flag vector, either in the absence or in the presence of Beclin 1-EGFP. Myc-Vps34-Vps15 was immunoprecipitated by an anti-Myc antibody and used for the in vitro kinase assay. The resulting radioactive PI(3) P was separated by TLC, quantified and normalized against the amount of immunoprecipitated Myc-tagged Vps34, as measured by western blotting (upper panel). The quantified results (lower panel) show that overexpressing Rubicon significantly downregulated the Vps34 kinase activity to 0.58-fold, but only without Beclin 1 overexpression (*P = 0.04, one-tailed Student's t-test with unequal variances, n = 4). (d) Effect of overexpressing Flag-Rubicon on autophagosome acidification, as monitored by mCherry-GFP-LC3 fluorescence. HeLa cells were transiently co-transfected with mCherry-GFP-LC3 and Flag-Rubicon (or control Flag vector). Cells co-expressing mCherry-GFP-LC3 and control Flag vector contained many red-only puncta along with yellow (indicating the presence of both red and green) puncta, suggesting the presence of both autolysosomes and nascent autophagosomes (upper panel). In contrast, cells co-expressing mCherry-GFP-LC3 and Flag-Rubicon contained primarily yellow or white puncta, suggesting the presence of only nascent autophagosomes (lower panel, white arrows). Notably, some cells, which were co-transfected with mCherry-GFP-LC3 and Flag-Rubicon but expressed high levels of mCherry-GFP-LC3 and undetectable levels of FLAG-Rubicon, contained many red-only puncta (lower panel, yellow arrows). (e) Quantification of the results in d show that overexpressing Flag-Rubicon markedly reduced the percentage of red-only puncta (mCherry-LC3) from 39% in the control Flag vector-transfected cells to 2% in the Flag-Rubicon-transfected cells (*P = 2 × 10−26, one-tailed Student's t-test with unequal variances, n = 30), indicating that overexpression of Rubicon blocks autophagosome acidification or maturation.
