Anti-tumor effects of USP18 silence were rescued by overexpression of POU4F1 in LUAD cells. Four groups: sh-NC, sh-USP18, sh-USP18 + pcDNA, sh-USP18 + POU4F1 were set in H1299 and A549 cells. (A-D) Examination of proliferation (A), migration (B) and apoptosis (C-D) through colony formation assay, wound healing assay and flow cytometric assay. (E-G) ROS (E), MDA (F), and GSH (G) levels were measured via kits. (H) Fe2+ level detection using iron level assay. nP < 0.01, mP < 0.001
