在工业化国家,高血压影响大约20%至30%的个体,并且通常被认为是基于遗传和环境因素而发展的。对最常见的高血压形式(通常称为“原发性”高血压)易感的基因的鉴定受到以下事实的阻碍,即血压是一种定义不清的表型,其受多种因素如性别、种族、体重等调节,高血压的定义取决于一个相当随意选择的临界值。因此,在鉴定罕见的常染色体显性形式的高血压(如Liddle病)的基因方面取得了更多进展。本文综述了一种实验方法,试图确定候选基因的原发性高血压使用永生化细胞的特点正常血压和高血压受试者。从目前可用的结果,一个有吸引力的推测是,增加细胞内信号转导引起的Gj型G蛋白的反应性增强代表了遗传固定的性状,使受影响的个体易患原发性高血压。
Hypertension affects approximately 20 to 30% of individuals in industrialized countries, and is commonly believed to develop on the basis of both genetic and environmental factors. The identification of genes susceptible to the most frequent form of hypertension, commonly referred to as "essential" hypertension, is hampered by the fact that blood pressure is a poorly defined phenotype that is modulated by multiple factors, such as gender, race, body mass etc., and that the definition of hypertension depends on a rather arbitrarily chosen cut-off value. Hence, more progress has been made in the identification of genes responsible for rare autosomal dominant forms of hypertension, such as Liddle's disease. This review focuses on an experimental approach that attempts to define candidate genes for essential hypertension using immortalized cells from well characterized normotensive and hypertensive subjects. From the presently available results, one attractive speculation is that an increased intracellular signal transduction caused by an enhanced reactivity of Gj-type G proteins represents a genetically fixed trait that renders affected individuals susceptible to essential hypertension.
