RESUMO
Among the topics studied in physiology and aging, a hormone has been drawing attention from the scientificcommunity: the Atrial Natriuretic Peptide (ANP). The ANP, which is produced by the cardiac atria, hasdemonstrated decisive action in endocrine mechanisms of action inhibiting sodium reabsorption in nephrons,revealing a direct influence on physiological mechanisms linked to aging and chronic stress.The overall objectiveof this study was to assess and analyze scientific literature on the ANP in the Pubmed database from 2010 to2012. 30 articles were collected, verifying authorship and gender division of species, instruments and typesof research. The results showed that the research of multiple authorship appeared mostly with 99.1%, being51.8% of male authorship, 17.9% of female authorship and 29.5% of publications not identified. Researchwith only one author appears with 0.8% in total. As the types of species used, it was observed 50.3% of theworks with humans, 40% with animals and 6.7% mixed (animal / human). As to the instruments used, thebiochemical markers were the ones that stood out, with 30%, followed by label arterial pressure with 12, 2%,drugs, with 11.1% and microscopic studies with 10%. In the typology of research, biochemical research appearsfirst, with 33.3%, followed by research morphophysiological/biochemical research, with 30%, Physiological/ biochemical, with 26.7%, Physiological with 6.7% and Morphophysiological with 3.3%. We can concludethat the publications about the hormone ANP are still little explored when the focus is aging. In the analyzedpublications, there is important information about the physiological and biochemical role of ANP as well ason their molecular composition.
