MLXIPL and metabolic syndrome: Additionally, we examined the expression of pivotal genes involved in fatty acid and lipoprotein uptake, lipogenesis, lipolysis, fat oxidation, and thermogenesis in these tissues, as well as the expression of the ChREBP target gene FGF21, because recent reports demonstrated that postprandial dyslipidemia and fatty liver might modulate postprandial FGF21 levels in humans and mice [20,21].
