One of the most potent stimuli for ANP secretion is the endothelial cell derived peptide, endothelin-1. Lew and Baertschi [37,38] demonstrated this important relationship by co-culturing cardiac myocytes and endothelial cells, which resulted in enhanced ANP secretion. Fukuda et al.
The heart contains 4 chambers - the atria (left and right) and the ventricles (left and right). When the level of blood entering the heart increases, the heart muscle cells stretch. This stimulates the release of ANP by the atria and a similar hormone, BNP (brain natriuretic peptide) by the ventricles. ANP is effectively a âmaydayâ hormone. Cells in the heart walls secrete ANP to tell the rest of the body that the heart is experiencing a rising influx of blood. ANP counteracts renin (made by the kidneys), aldosterone (made by the adrenal gland), and angiotensin II, 3 hormones that increase blood pressure.
