DJ-1 reduces RRPs apoptosis. (A) DJ-1 overexpression reduces RRPs apoptosis. Blue indicates DAPI-stained nuclei, while red indicates TUNEL-positive cells. (B) Quantification of TUNEL staining showing that the DJ-1 overexpression group showed lower apoptosis levels than the HG group. (C,D) After DJ-1 overexpression, Bcl-2 protein levels increased, BAX protein levels decreased, and the Bcl-2/BAX ratio increased. All data are presented as means ± SEM(n = 3/group). *P < 0.05 vs NC; #P < 0.05 vs NC, HG.
