mTOR-Controlled Autophagy Requires Intracellular Ca2+ Signaling
Figure 1
Time- and concentration-dependent stimulation of autophagy by rapamycin.
A–B) Western-blot analysis for GAPDH and LC3 of protein lysates obtained from HeLa cells treated with DMSO or 1 µM rapamycin (Rapa) for the indicated time periods (A) (n = 7) or for 5 h with the indicated concentrations (B) (n = 6). One hour before harvesting, 100 nM bafilomycin A1 was added. Upper panels: representative Western blots; lower panels: quantification of the LC3-II/GAPDH ratio. C) GFP-LC3-punctae quantification in HeLa cells treated for 5 h with different concentrations of rapamycin. Left: representative pictures. The scale bar represents 10 µm. Concentrations are mentioned in the right lower corner. Right: Quantification of the number of punctae per cell (n = 3). * p<0.05, repeated measurements ANOVA.
