Casein Kinase 2-Interacting Protein-1 Alleviates High Glucose-Reduced Autophagy, Oxidative Stress, and Apoptosis in Retinal Pigment Epithelial Cells via Activating the p62/KEAP1/NRF2 Signaling Pathway

Figure 6

CKIP-1 alleviates apoptosis induced by high glucose. ((a) and (b)) The apoptotic cells were measured by flow cytometry and analyzed by flow Jo. ((c) and (d)) The apoptosis-associated markers were evaluated by Western blot.  < 0.001 vs. NG.  < 0.001 vs. HG.  < 0.001 vs. HG + NC.  < 0.05 and  < 0.001 vs. HG + CKIP-1. NG, normal glucose (5.5 mM); MG, mannitol (20 mM); HG, high glucose (25 mM); NC, pcDNA3.1 vector negative control; CKIP-1, pcDNA3.1-CKIP-1; ML385 (5 μM), the Nrf2 inhibitor.
