Mitochondrial autophagy of HTR-8/SVneo cells was not affected by CeO₂NPs exposure. A MitoSOX fluorescence was used to measure the mitochondrial superoxide in HTR-8/SVneo cells treated with different concentrations of CeO₂NPs for 24 h (Scale bar = 50 μm). B TOM20 and LC3 immunofluorescence staining of HTR-8/SVneo cells after exposure to different concentrations of CeO₂NPs for 24 h (Scale bar = 10 μm). C Western blot showed the expression of Phb2, PINK1, and Parkin in HTR-8/SVneo cells treated with different concentrations of CeO₂NPs for 24 h
