Role of Apolipoprotein A-IV in Reverse Cholesterol Transport
Apolipoprotein (apo) A-IV was first described by Swaney and colleagues in 1974  in rat plasma high-density lipoprotein (HDL) and subsequently shown by a number of investigators to be an apoprotein component of lymph lipoproteins, plasma chylomicrons, very low density lipoproteins, and high-density lipoproteins and also to occur in a substantial amount unassociated with lipoproteins in a variety of mammalian species including man (for review see [22, 25]. Besides the liver the intestine is a major source of synthesis of this apoprotein . Whereas little is known about the hepatic synthesis of apo A-IV, the intestinal induction of this apoprotein has been studied in more detail. In primary cultures of nonproliferating rat hepatocytes dexamethasone and insulin increased apo A-IV mRNA substantially and could be shown to act synergistically when applied simultaneously .
