The absolute blood pressure (BP) reductions with aprocitentan are in the ranges established as a surrogate for reduction in cardiovascular morbidity in hypertension. Significant changes in BP with aprocitentan are observed within 14 days, and its BP-lowering effects have also been documented with ambulatory BP monitoring. Finally, aprocitentan enhances the BP-lowering effects of other antihypertensive drugs, including renin-angiotensin-system blockers. In conclusion, aprocitentan ameliorates the effects of ET-1 and could potentially reduce BP and provide broader cardiovascular protection in patients with resistant hypertension. Available data support the hypothesis that this new agent could expand our antihypertensive arsenal in resistant hypertension, making aprocitentan an attractive candidate for further large-scale trials.SIRT1 is a deacetylase with multiple physiological functions by targeting histones and non-histone proteins. It has been shown that SIRT1 activation is involved in neuroprotection in Parkinson's disease (PD) models. In the present study, we provided direct evidences showing the neuroprotective roles of SIRT1 in dopaminergic neurons. Our data showed that increased expression of SIRT1 plays beneficial roles against MPP+ insults in SH-SY5Y cells and primary dopaminergic neurons, including increased cell viability, reduced LDH release, improved the mitochondrial membrane potential (MMP), and attenuated cell apoptosis. On the contrary, knockdown of SIRT1 further aggravated cell injuries induced by MPP+. Moreover, mutated SIRT1 without deacetylase activity (SIRT1 H363Y) failed to protect dopaminergic neurons from MPP+ injuries. Mechanistically, SIRT1 improved PGC-1α expression and mitochondrial biogenesis. Knockdown of PGC-1α almost completely abolished the neuroprote
