CRABP2 and cancer: The oxidative phosphorylation pathway gene expression was significantly increased (Fig. 3D), indicating that CRABP2 is involved in the regulation of oxidative phosphorylation, and overexpression of CRABP2 can induce the expression of fatty acid oxidative metabolism-related genes such as CYP4A11 (Fig. 3B), suggesting that CYP4A11 may mediate CRABP2 to promote cancer cell oxidation phosphorylation.
