doi: 10.1038/s41538-025-00654-x

Figure Lengend Snippet: A Blue: Nuclei. Purple: Mitochondrial. Red: PINK1/Parkin/p62/LC3B. IF staining was performed to detect PINK1, Parkin, p62, and LC3B protein levels (magnification: 100×, scale bar: 15 μm). B Colocalization analysis of p62, LC3B, and mitochondria was performed using ImageJ software. C Colocalization Pearson correlation coefficient analysis were obtained based on IF images of p62 and LC3B ( n = 6). D Western blot analysis of PINK1 and LC3B expression in renal cortical tissues from different experimental groups. Quantification of gray values for Western blotting results in ( D ) was performed using ImageJ ( n = 3). E Blue: Nuclei. Red: E-cadherin/N-cadherin/Vimentin. IF assay was performed to detect E-cadherin, N-cadherin and Vimentin protein levels (magnification: 100×, scale bar: 15 μm).
