摘要：Apolipoprotein (apo) B is the structural protein moiety of plasma low density lipoprotein (LDL), an important risk factor for coronary heart disease (CHD). There is evidence that the rate of synthesis of apoB-containing lipoproteins may play an important role in the regulation of plasma LDL levels. However, it is generally thought that transcriptional regulation of the apoB gene is not a significant determinant of the synthesis of apoB-containing lipoproteins, and by inference, of the regulation of the plasma LDL concentration. Here we report the discovery of a common polymorphism in the promoter region of the apoB gene, a C to T substitution at position −516. The −516T allele is associated with an increase in the basal transcription of the apoB gene (+41%, P P P It is concluded that variation in the rate of transcription of the apoB gene can affect plasma LDL levels and influences the risk of CHD in middle-aged men. —van 't Hooft, F.
