Supplementary Figure 3: Analysis of c-Myc regulators and PP2A-C substrates in AMBRA1-defective cells.

(a) Protein extracts from AMBRA1 knocked-down cells were analysed by western blot using antibodies against AKT, phospho-AKT, GSK3B and phospho-GSK3B. (b) Western blot analysis of phospho-Erk1/2 and total Erk1/2 in Ambra1 +/+ and Ambra1gt/gt MEFs.
