title: Regulation of hepatic and non-hepatic apolipoprotein A-I and E gene expression during liver regeneration.
abstract: In this study, we have determined what tissues other than liver express apolipoprotein (apo) A-I and apo E genes during liver regeneration at the level of the specific mRNAs, and have compared these findings with the serum values of high-density lipoprotein (HDL), low-density lipoprotein (LDL) and very-low-density lipoprotein (VLDL). Our results show that liver and intestine express most of the apo A-I mRNA during liver regeneration. Although apo E mRNA is expressed principally by the liver, its expression is reduced in liver during regeneration but is increased markedly in non-hepatic tissues, such as in intestine, kidney, lung and brain. These results suggest that humoral or circulating factors released during liver regeneration influence apolipoprotein E gene expression, not only in hepatic but also in non-hepatic tissue.
