Updated project metadata. In this project two sets of proteomic experiments were performed: (1) Autophagosome content profiling: Autophagosomes were isolated from cultured primary lung endothelial cells of LC3-GFP and WT mice using anti-GFP uMACS (n=3 biological replicates). (2) Expression proteomics: Protein lysates from endothelial cells of n=3 young and old WT mice, young and old vecCRE-ATG5flox mice (ATG5 KO mice).
