Atrial Natriuretic Peptide (ANP) (1-28), human, porcine Acetate is a bioactive peptide that plays a crucial role in the body's homeostatic mechanisms. Atrial Natriuretic Peptide (ANP) (1-28) inhibits angiotensin II)-induced endothelin-1 secretion in a dose-dependent manner[1]. Atrial Natriuretic Peptide (ANP) (1-28) is primarily secreted by atrial myocytes in response to increased atrial stretch, such as during volume overload. The 28-amino-acid sequence is highly conserved between human and porcine forms. The acetate modification may affect its solubility, stability, and biological activity to some extent[2]. Atrial Natriuretic Peptide (ANP) (1-28) binds to its specific receptors, mainly the guanylyl cyclase-linked natriuretic peptide receptor-A (NPR-A). The binding activates guanylyl cyclase, leading to an increase in intracellular cyclic guanosine monophosphate (cGMP) levels. Elevated cGMP then mediates a series of physiological effects. In the kidneys, Atrial Natriuretic Peptide (ANP) (1-28) promotes natriuresis (increased sodium excretion) and diuresis (increased urine output), which helps to reduce blood volume. The peptide achieves this by increasing the glomerular filtration rate, inhibiting sodium reabsorption in the renal tubules, and suppressing the renin-angiotensin-aldosterone system (RAAS)[3]. Atrial Natriuretic Peptide (ANP) (1-28) causes vasodilation of blood vessels, reducing peripheral vascular resistance and thus lowering blood pressure. Atrial Natriuretic Peptide (ANP) (1-28) also has anti-fibrotic and anti-hypertrophic effects on the heart, helping to prevent cardiac remodeling and maintain normal cardiac function[4].
In vitro, Atrial Natriuretic Peptide (ANP) (1-28) (10nmol/L) pretreated human embryonic kidney cells (HEK 293) for 30 minutes, significantly inhibited the aldosterone (500pmol/L)-induced nuclear translocation of the mineralocorticoid receptor (MR)[5]. Atrial Natriuretic Peptide (ANP) (1-28)(100nM) pretreated human pulmonary artery endothelial cells (HPAECs) for 20 minutes, significantly inhibited the increase in endothelial cell permeability induced by thrombin (0.5units/mL). Atrial Natriuretic Peptide (ANP) (1-28) inhibits the secretion of endothelin-1 in a dose-dependent manner, thereby suppressing the Rho signaling pathway, reducing myosin light chain (MLC) phosphorylation, and inhibiting stress fiber formation, thus alleviating cell contraction and increased permeability[6].
In vivo, Atrial Natriuretic Peptide (ANP) (1-28)(2µg in 400µL PBS per mouse) was intraperitoneally injected into mice with DSS-induced colitis. Atrial Natriuretic Peptide (ANP) (1-28) treatment significantly alleviated colonic inflammation by inhibiting the STING pathway, reducing the expression of inflammatory cytokines such as TNF-α, IL-1β, IL-6, IFN-α, and IFN-β in colonic tissues and epithelial cells. Atrial Natriuretic Peptide (ANP) (1-28) also repaired gut barrier function by promoting the expression of tight junction proteins (ZO-1 and occludin) and inhibited ER stress-induced autophagy via the STING pathway[7]. Atrial Natriuretic Peptide (ANP) (1-28)(2.5µg/kg) was administered to wild-type mice via tail vein injection. Atrial Natriuretic Peptide significantly increased the levels of the autophagy marker LC3-II in the mouse heart and reduced infarct size in ischemia-reperfusion (I/R) injury[8].
