The PhD project is about the Regulation of vascular tone by endothelium. It involves studying the effects of methylated arginine analogues such as monomethyl arginine (L-NMMA) and asymmetric dimethylarginine (ADMA) on nitric oxide (NO) activity in rat aorta using organ baths containing Krebs solution at 37 ˚C and gassed with 95% O2 and 5% CO2. These two inhibitors of endothelial nitric oxide synthase enzyme (eNOS) showed an anomalous action, as they inhibited basal NO activity (assessed by enhancement of phenylephrine-induced tone and by blocking relaxations produced by superoxide dismutase or the PDE5 inhibitor; T0156) but not that is stimulated by agonists like acetylcholine or the calcium ionophore A23187. After establishing these findings I will try to find the reason(s) for these paradoxical actions of these two endogenously synthesized inhibitors of eNOS.
