(A-C) Atg7+/+ and Atg7-/- MEFs stably expressing GFP‐Gal3 (A, C) or GFP‐Ub (B) were treated with 1000 μM LLOMe or 250 μg/ml silica for 3 h. Cells were subjected to immunocytochemistry using the following antibodies: anti‐LC3 and anti‐Lamp1 (A), anti‐p62 and anti‐Lamp1 (B), or anti‐FK2 and anti‐p62 (C). Bars: 10 μm.
