PLIN5 and steatosis: The expression of Plin5 was positively correlated with increased steatosis in cardiac, skeletal muscle, and liver tissue [30, 71–74] but negatively correlated with the expression of oxidative metabolism-related gene (such as PPAR-α, PGC-1α, and related genes), mitochondrial function indicators, and FA oxidation level in the heart [71, 72].
