Molecular cell:高血压药物开发新契机 单基因调控血压

2015-05-12 佚名 生物谷

近日,来自日本理化研究所的研究人员在国际学术期刊molecular cell发表了一篇文章,对血压调控机制进行了深入探讨。高血压是导致中风,心脏病和糖尿病的重要风险因素,了解自然状态下身体如何调节血压对于开发治疗高血压的方法策略,将血压控制在正常水平具有重要意义。   在该项研究中,来自日本理化研究所的研究人员发现一个定位在内质网的多功能蛋白--ERp44缺失小鼠血压低于正常血压

近日,来自日本理化研究所的研究人员在国际学术期刊molecular cell发表了一篇文章,对血压调控机制进行了深入探讨。高血压是导致中风,心脏病和糖尿病的重要风险因素,了解自然状态下身体如何调节血压对于开发治疗高血压的方法策略,将血压控制在正常水平具有重要意义。
 
在该项研究中,来自日本理化研究所的研究人员发现一个定位在内质网的多功能蛋白--ERp44缺失小鼠血压低于正常血压,并且在该小鼠模型中循环系统维持血压的重要多肽激素--血管紧张素II其清除速度快于正常小鼠,为ERp44缺失小鼠血压低于正常水平提供了一个合理解释。为确定血管紧张素II为何在ERp44缺失小鼠的血液中清除速度快于正常小鼠,研究人员对细胞内与ERp44具有相互作用的蛋白进行了筛选,并且这种蛋白还能够离开细胞进入血液,与血管紧张素发生相互作用。
 
经过筛选,研究人员发现可以切割类似血管紧张素的多肽的氨肽酶--ERAP1能够在内质网氧气浓度较高时与ERp44结合,并在内质网氧浓度下降时释放入血。在ERp44缺失小鼠模型中,由于ERp44缺失,几乎所有的ERAP1都释放入血,随后对血管紧张素II进行切割,导致敲除小鼠的血压低于正常水平。除此之外,研究人员还发现,在系统性感染过程中,血压会急剧下降,而此时,细胞中ERp44表达增加,导致与ERAP1结合增加,降低了ERAP1入血,从而维持了血液中血管紧张素II的稳定,保证血压不会进一步下降。
 
最后研究人员总结道,目前治疗高血压的策略主要是通过靶向产生血管紧张素II的酶,而该项研究为高血压治疗提供了新的线索,靶向类似ERAP1和ERp44的蛋白活性也可达到控制血压的目的。这项研究对于高血压和相关疾病治疗及药物开发具有重要意义。
