dc.description.abstractThe biological activity of the proline rich decapeptde Bj PRO 10c a processing product of the C type natriuretic peptide precursor protein, expressed in the brain and the venom gland of the pit viper Bothrops jararaca, was originally attributed to the inhibition of the somatic angiotensm converting enzyme activity with subsequent ant hypertensive effect However recent results suggest broader biological activity may also be involved in the cardiovascular effects of this peptide Here we show that Bj PRO 10c enhances and sustains the generation of nitric made (NO) by regulating argininosuccinate synthase activity and thereby velocity of the citrulline NO cycle Bj PRO 10c-mediated effects not restricted to the cardiovascular system since NO production was also induced in cells of astroglial origin Bj PRO 10c was internalized by C6 astroglioma cells where it induces NO production and upregulation of the citrulline NO cycle cells in a dose dependent fashion in view of that, astroglial cells function as L arginine pool for NO production in neighboring neurons, we suggest a regulatory function for Bj PRO-10c on the metabolism of this gaseous neurotransmitter in the CNS Moreover, proliferation of astroglial cells was reduced in the presence of Bj PRO 10c however, cell death was not induced Since NO donors have been studied for the treatment of solid cancers Bj PRO 10c may serve as structural model for developing drugs to improve the effects of cancer therapy based on the peptide's ability to augment NO production (C) 2010 Elsevier B V All rights reserveden
