However, from the research progress made so far, there are roughly the following viewpoints on the molecular mechanism of hypertension: the first is that the renin-angiotensin-aldosterone system (RAAS) controls the degree of vasoconstriction and then regulates hypertension [36]; the second view is that the regulation of the nervous system leads to the production of hypertension [37]. Here, REN is linked to Hypertension.
