NO Inhibits Autophagosome Synthesis.Figure 1(A) Immunoblot analysis with anti-LC3 antibody shows that NO donors reduced LC3-II levels in rat primary cortical neurons and decreased autophagosome synthesis in bafilomycin A1-treated rat primary cortical neurons and HeLa cells. (B-E) Confocal microscopy images and analysis of autophagic flux by automated Cellomics microscopy show that NO donors reduced autolysosome numbers in mRFP-GFP-LC3 HeLa cells grown in full medium (FM) (B and D) or starved with HBSS (C and E). Cells in HBSS had more autolysosomes compared to FM (C). Autolysosome number in untreated cells in FM is set at 100%. (F) NO donors increased EGFP-HDQ74 aggregates in a dose-dependent manner in EGFP-HDQ74-transfected Atg5+/+, but not in Atg5−/−, MEFs. Atg5−/− MEFs had more EGFP-HDQ74 aggregates than Atg5+/+ MEFs. (G and H) Confocal microscopy images (H) and immunofluorescence analysis with anti-Atg16 antibody (G) show that NO donors reduced the percentage of HeLa cells with Atg16-positive structures (arrows) under starvation.
