Effects of vimentin on autophagy and Akt-mediated transformation. (A) GFP-LC3 dots in Rat2 cells transduced with indicated vimentin shRNA and transfected with GFP-LC3. Bars represent mean ± SEM of triplicate samples with >50 cells analyzed per sample. Similar results observed in 3 independent experiments. (B) Biochemical assessment of autophagy in Rat2 cells transduced with indicated vimentin shRNA and myr-Akt1 or control vector. (C) Soft agar colonies formed by Rat2 fibroblasts transduced with indicated vectors. Bars represent mean ± SEM of triplicate samples of ≥12 random images analyzed by ImageJ. (D) Speculative model for relations between Akt phosphorylation of Beclin 1; formation of a complex with Beclin 1, 14-3-3 proteins, and intermediate filament (IF) proteins; autophagy, and tumorigenesis. *P<0.05, **P<0.01, ***P<0.001; t test. In (A) and (C), all comparisons are with the first bar in graph.
