(f) Effect of oxidative stress on the autophagy activity in Atg5 Tg MEFs. WT MEFs no. 1 and Atg5 Tg MEFs no. 6 were treated with 100 μM H2O2 for 24 h in the presence or absence of 20 nM Baf.A1, and cell extracts were analysed by western blotting. About 10 and 30 μg of proteins were used for LC3 (upper panel) and p62 (bottom panel) detection, respectively. β-Actin served as a control.
