UCP2 and fatty liver disease: Interestingly, several genes protective of hepatic steatosis and fibrosis have recently been reported, namely, mitochondrial amidoxime-reducing component 1 (MARC1), 17β-hydroxysteroid dehydrogenase 13 (HSD17B13), LPIN1, uncoupling protein 2 (UCP2), interleukin-28B (IL-28B), Kruppel-like factor 6 (KLF6), and the MER protocol-oncogene tyrosine kinase (MERTK) [111].
