摘要

采用定量性状位点(QTL)方法研究应激敏感性高血压的遗传基础。采用2组不同年龄(3 ~ 4月龄和6月龄)F2(遗传性应激性动脉高血压[ISIAH] × Wistar albino Glaxo [WAG])杂交雄性,测定静息、应激状态下血压和体成分性状。确定了几个新的性状位点。在不同年龄的大鼠中,血压和器官重量的一些基因位点被定位到相同的遗传区域。两组不同年龄大鼠QTL效应的动态变化可能反映了应激敏感性高血压的发展过程。

The genetic control of blood pressure and body composition in rats with stress-sensitive hypertension.

The genetic basis of the stress-sensitive arterial hypertension was investigated using the quantitative trait loci (QTL) approach. Two groups of F2 (inherited stress-induced arterial hypertension [ISIAH] × Wistar albino Glaxo [WAG]) hybrid males of different age (3-4 months old and 6 months old) were tested for blood pressure at rest and stressed conditions and for body composition traits. Several novel loci for the traits were determined. Some loci for blood pressure and organ weight were mapped to the same genetic region in rats of different age. The dynamic change of QTL effects in two rat groups of different age might reflect the process of stress-sensitive hypertension development.
