(c) Wild-type HeLa and H1299 cell lines were cultured either in fed or starved conditions with EBSS and 10 μM hydroxychloroquine (HCQ), as indicated. Cells were treated at the same time with SAR405 at different concentrations. LC3-II was measured by western blotting, and GAPDH was used as a loading control. One representative experiment for three independent experiments is shown. Full-length blots are shown in Supplementary Figure 18. (d) Histograms show the LC3-II/GAPDH ratio for each condition in the two cell lines. Black and gray histograms correspond to fed condition and EBSS conditions, respectively. The addition of hydroxychloroquine at 10 μM is indicated. Values were normalized to 1 for fed conditions. Data show mean ± s.d. for three independent experiments.
