PLTP and steatosis: To decipher the molecular basis of Kit-dependent steatosis, we determined the expression profiles of key genes involved in lipid hepatic metabolism: such as apoliproteins (Apoa1, ApoB), lipoprotein receptors (LdlR, VldlR, Scarb1, Lrp1), lipase (Lipc, LipH, Lpl) and others implicated in hepatic lipidogenesis (Scap, Srebf1, Srebf2), lipid secretion (Pltp, Mttp, Abca1), bile acid synthesis (Cyp8b1, Cyp7a1), lipid transport (Slc10a1, Abcb11, Abcb1a, Abcc2) and a lipodystrophy gene, Lipin 1 (Lpin1), encoding a phosphatidate phosphatase enzyme with transcription activity [26-28].
