Genetics of hypertension 总被引:4,自引:0,他引:4
In the past year, substantial progress has been made in both mapping and fine mapping the genes involved in blood pressure regulation. Genome scans have been carried out in humans and mice and these reveal many new potential chromosomal locations for blood pressure susceptibility loci. The chromosomal regions containing blood pressure genes for many of the inbred hypertensive rat models have been refined using new congenic strains. Further genetic studies support a role for antiotensinogen, aldosterone synthase and a region close to the epithelial sodium channel in blood pressure regulation. Finally, comprehensive single-nucleotide polymorphism analysis of cardiovascular genes has been undertaken using chip technology. 相似文献

Numerous epidemiological studies suggest an inverse relationship between low birth weight (LBW) and hypertension, an observation now supported by numerous animal studies. The mechanisms linking LBW and hypertension appear to be multifactorial and involve alterations in the normal regulatory systems and renal functions involved in the long-term control of arterial pressure. Recent studies using animal models of fetal programming suggest that programming during fetal life occurs in response to an adverse fetal environment and results in permanent adaptive responses that lead to structural and physiological alterations and the subsequent development of hypertension. This review summarizes the adaptive responses observed in the different models used to induce a suboptimal fetal environment and discusses insights into the mechanisms mediating the fetal programming of hypertension. 相似文献
