| abstractText | Three separate lines of transgenic mice were created with integrated copies of an 11.1-kilobase pair human DNA fragment containing the apolipoprotein (apo) E gene. The endogenous mouse apoE gene is primarily expressed in the liver with varying levels of expression in other tissues. However, in all three transgenic lines high levels of human apoE mRNA were detected only in the kidney, with lower levels found in the liver and other tissues; despite this profile of human apoE mRNA, human apoE was found in the plasma of the transgenic mice at levels comparable to those found in human plasma. All of the human apoE in the plasma of the transgenic mice was associated with lipoproteins. These results suggest that the domain responsible for the high level of apoE expression in liver lies outside of the microinjected DNA fragment and that an ectopic site of expression of an introduced gene may be permissive for the accumulation of its protein in plasma. |
