Key result
The local renin-angiotensin system plays a regulatory role in female reproductive physiology, including follicular development and angiogenesis, and its dysregulation is implicated in preeclampsia, ovarian cancer, and endometrial cancer.
The local renin-angiotensin system plays a key role in female reproductive physiology and gynecological cancers, highlighting its potential as a therapeutic target.
Local RAS in reproductive tissues warrants caution with RAS inhibitors in fertility patients; leaves open mechanistic roles in reproductive disorders.
The renin-angiotensin system (RAS) is well known as regulator of electrolytes and blood pressure. Besides this function, there are numerous studies supporting the idea of a local tissue RAS. This system controls the local activity of the different RAS family members, especially of the functional proteins Angiotensin II and Angiotensin (1-7). Those antagonistically acting proteins have been described to be expressed in different organ systems including the human reproductive tract. Therefore, this local RAS has been suspected to be involved in the control and regulation of physiological and pathological conditions in the female reproduction tract. This review of the available literature summarizes the physiological influence of the RAS on the follicular development, ovarian angiogenesis, and placental- and uterine function. In addition, in the second part the role of the RAS concerning ovarian- and endometrial cancer becomes elucidated. This section includes possible novel therapeutic strategies via inhibition of RAS-mediated tumor growth and angiogenesis. Looking at a very complex system of agonistic and antagonistic tissue factors, it may be supposed that the RAS in the female reproduction tract will be of rising scientific interest in the upcoming years.

Herr et al. (2013) conducted a review in Physiological and pathological conditions of the female reproductive tract (including ovarian cancer, endometrial cancer, and preeclampsia). Local renin-angiotensin system (RAS) was evaluated. The local renin-angiotensin system plays a regulatory role in female reproductive physiology, including follicular development and angiogenesis, and its dysregulation is implicated in preeclampsia, ovarian cancer, and endometrial cancer.
