血管紧张素Ⅱ调控骨代谢的研究进展

骨组织中存在局部肾素-血管紧张素系统(RAS)。RAS组分及其活性肽血管紧张素Ⅱ(AngⅡ)直接参与调控骨代谢的病理生理进程。成骨细胞和破骨细胞都有AngⅡ的受体表达,这些受体介导了AngⅡ调控骨代谢的作用。该文回顾了经典RAS途径,探讨了组织RAS致局部组织病变的作用,并对RAS活性肽AngⅡ调控成骨细胞的靶基因、胞内信号通路、AngⅡ通过成骨细胞间接调控破骨细胞功能、AngⅡ受体在骨代谢调控中的交互作用进行了重点阐述。     

雌激素对组织肾素-血管紧张素系统介导的相关疾病的影响

Estrogen improves the pathological changes of the local tissues and organs and recovers the tissue function by regulating the activity of tissue renin-angiotensin system (RAS) and the expression of RAS components in the local tissues such as heart, blood vessel, kidney, adrenal gland, brain and skeleton. Therefore, tissue RAS is the biological regulating targets of estrogen. Here we review the pathophysiological roles of estrogen in the local tissue RAS by analyzing and summarizing the recent researches.
