Figure Lengend Snippet: Overexpression of BNIP3 promotes autophagy in renal cancer cells under hypoxia. (A) Immunofluorescence staining was used to detect the expression levels of LC3B (×40). (B) Mean fluorescence intensity of LC3B. (C) The autophagosomes in A498 and 786-O cells were visualized using transmission electron microscopy (TEM) at a magnification of ×20000 after exposure to hypoxia. (D-F) Western blot detection of LC3-I, LC3-II, and p62. (G, H) Overexpression of BNIP3 affecting A498 and 786-O cells ROS. (I) Concentration of mitochondrial membrane permeability transition pore (mPTP). Data are mean ± SD, * P < 0.05, ** P < 0.01.
