Key result
Acute ethanol ingestion in Wistar rats reduced BNP mRNA levels to 43% in atrial tissue and 38% in ventricular tissue compared to controls at 120 minutes, with no differences in ANP mRNA.
Why the study?
Does acute ethanol ingestion alter the gene expression of ANP and BNP in Wistar rats?
Does acute ethanol ingestion alter the gene expression of ANP and BNP in Wistar rats?
Acute ethanol ingestion significantly reduces BNP mRNA expression without affecting ANP mRNA in rat myocardium, suggesting differential regulation.

These rat findings warrant no clinical changes in natriuretic peptide interpretation; human relevance remains unknown.
Given that ethanol ingestion is associated with a disruption of water and electrolyte balance in addition to being a significant risk factor for cardiovascular disease, we have investigated the gene expression of ANP and BNP in response to acute doses of ethanol. Wistar rats were administered either a 5 g/kg dose of ethanol or an equivalent volume of water, and atrial and ventricular tissue samples were removed at 30, 60, and 120 min for analyses. Although no differences in ANP mRNA were observed between ethanol and water-treated rats during the time course, BNP mRNA levels in ethanol-treated rats were 43% of those present in water-treated animals in atrial tissue at 120 min. In ventricular tissue, BNP mRNA levels were reduced similarly to 38% of control. These results suggest a possible differential regulation of A- and B-type natriuretic peptides under the influence of ethanol ingestion.
