Abstract Essential hypertension is a major risk factor for cardiovascular morbidity and mortality, and the early-diagnosis is very important for the prevention of essential hypertension. Previously, we found that Pin1, the only known enzyme isomerizing pSer/pThr-Pro motifs in proteins, may gradually become inactive under conditions of stress such as intracellular acidification and fever. Interestingly, essential hypertension and the dysfunction of Pin1 often synchronously occur with the increasing age. Recent evidence indicates that Pin1 primarily increases the activity of endothelial nitric oxide synthase (eNOS) and the production of nitric oxide (NO) in multiple ways, significantly promoting the relaxation response of blood vessels and preventing the elevation of blood pressure. Further, the inhibition of Pin1 results in significantly increased blood pressure in rats. So, we hypothesized and evaluated the potential of Pin1 to be a new early-diagnostic biomarker as well as a therapeutic drug for essential hypertension. The unique activity of Pin1 and some epidemiological and experimental data evidence that the decreased activity of Pin1 may be closely associated with the development of essential hypertension. The factors that may impact the activity of Pin1 and correlate with the risk of essential hypertension were also discussed. These findings indicate that Pin1 plays a key and permanent role in efficiently preventing the development of essential hypertension, and that Pin1 may be a promising early-diagnostic biomarker as well as an effective therapeutic drug for the early-diagnosis, prevention, and treatment of essential hypertension, potentially decreasing the risk of cardiovascular morbidity and mortality.
