METTL3/PSAT1 regulated HG-mediated ARPE-19 cell viability and oxidative stress in vitro. (A and B) PSAT1 expression was determined in ARPE-19 cells transfected with sh-NC or sh-PSAT1 using RT-qPCR assay and Western blot assay. (C-F) ARPE-19 cells were treated with NG, HG, HG + sh-PSAT1, or HG + sh-PSAT1 + sh-PSAT1. (C) CCK-8 analysis of cell viability in treated ARPE-19. (D-F) Commercial kits were applied to analyze ROS, MDA, and GSH-Px levels in treated ARPE-19 cells. *P < 0.05, **P < 0.01, ***P < 0.001, n = 3
