Figure 3. Accumulation of endogenous LC3 positive structures in cells exposed to increasing concentrations of BEO.
SH-SY5Y cells were exposed to vehicle (ethanol 0.018%) or BEO (0.005–0.02%) for 30 minutes and immunostained with anti-LC3 antibody; nuclei were counterstained with DAPI. Confocal analysis of endogenous LC3 intracellular distribution shows a dose-dependent increase of LC3 puncta (autophagosomes) in cells treated with BEO 0.01% and 0.02% as compared to vehicle or BEO 0.005% treated cells. The described patter of LC3 distribution was observed in three independent experiments.
