Additional file 3 of Autophagy inhibition improves the cytotoxic effects of receptor tyrosine kinase inhibitors

Abstract

Additional file 3: Figure S3. Expression of extracellular signal-regulated kinase (ERK) upon treatments. Increasing concentrations of RTKi were used for the treatment, and levels of phospho-mTOR, phospho-PI3K, phospho-AKT and phospho-ERK (pERK) and total ERK were evaluated by western blot. GAPDH served as a loading control protein. D = DMSO; the numbers indicate the concentrations used in μM
