A hormone response element in the human apolipoprotein CIII (ApoCIII) enhancer is essential for intestinal expression of the ApoA-I and ApoCIII genes and contributes to the hepatic expression of the two linked genes in transgenic mice.

Abstract excerpt

We have generated transgenic mice carrying wild-type promoters of the human apolipoprotein A-I (apoA-I)-apoCIII gene cluster or promoters mutated in their hormone response elements. The wild-type cluster directed high levels of apoA-I gene expression in liver and intestine, moderate expression in kidney, and low to minimal expression in other tissues. It also directed high levels of chloramphenicol...
