“…We found cells with an endosomal-like pool of mTOR (top), others with a highly perinuclear-pattern (bottom left), as well as others with a cytosolic pool (bottom right). mTOR-positive membranes were found to colocalize with Rab7 (a small GTPase involved in lysosome biogenesis and maturation of late autophagic compartments 8,[11][12][13] (Fig. 1B).…”

“…In cells coexpressing fluorescently-tagged RIα and LC3 (mammalian homologue of yeast Atg8 that specifically associates with membranes of mature autophagosomes [7][8][9] ), almost all RIα molecules were found to reside on LC3-positive membranes. Furthermore, in prkar1a -/-mouse embryonic fibroblasts the number of autophagosomes was reduced compared to the wild-type cells.…”

“…These fusion events indicate that maturation of autophagosome to autophagolysosome, in mammalian cells, is a multistep process. 17 This convergence between the endocytic and autophagic pathways has been reported in Leydig cells. In this study, the authors have visualized by electron microscopy that MVBs deliver their endocytosed markers (two type of lectins, concanavalin A (ConA) and wheat germ agglutinin (WGA)) to the early autophagosomes where the two pathways meet.…”

“…Regulated autophagy can promote cell survival by providing metabolic fuel for mitochondrial oxidation after lysosomal digestion of intracellular components (Eskelinen, 2005;Lum et al, 2005b). Indeed, cells incapable of apoptosis can survive for an extended time after growth factor withdrawal or nutrient deprivation by utilizing autophagy as a source of nutrients to support basal cell metabolism (Lum et al, 2005a;Degenhardt et al, 2006;Fung et al, 2008).…”
