Rab7 is a member of the Rab family involved in transport to late endosomes and in the biogenesis of the perinuclear lysosome compartment. To assess the role of Rab7 in autophagy we stably transfected CHO cells with wild-type pEGFP-Rab7, and the mutants T22N (GDP form) and Q67L (GTP form). Autophagy was induced by amino acid starvation and the autophagic vacuoles were labeled with monodansylcadaverine. By fluorescence microscopy we observed that Rab7wt and the active mutant Rab7Q67L were associated with ring-shaped vesicles labeled with monodansylcadaverine indicating that these Rab proteins associate with the membrane of autophagic vesicles. As expected, in cells transfected with the negative mutant Rab7T22N the protein was diffusely distributed in the cytosol. However, upon induction of autophagy by amino acid starvation or by rapamycin treatment this mutant clearly decorated the monodansylcadaverine-labeled vesicles. Furthermore, a marked increase in the size of the monodansylcadaverine-labeled vacuoles induced by starvation was observed by overexpression of the inactive mutant T22N. Similarly, there was an increase in the size of vesicles labeled with LC3, a protein that specifically localizes on the autophagosomal membrane. Taken together the results indicate that a functional Rab7 is important for the normal progression of autophagy."xsd:string |
