Fig. 1From: Autophagy contributes to the chemo-resistance of non-small cell lung cancer in hypoxic conditionsA549 cells exposed to 1 % hypoxia exhibit a time-dependent increase in HIF-1α expression. a: Cells were incubated under 1 % hypoxia for 0, 2, 4, 6 or 8 h. Western blots show HIF-1α expression with longer hypoxia durations. b: Western blot intensity was measured with Image J. Data are mean ± SEM, *p < 0.05.
