Supplementary information

Natriuretic Peptides A also known as ANP ANF or NPPA are important cardiac hormones made by atrial myocytes in the heart. This peptide with a mass of around 28 amino acids plays an important role mechanically in modulating blood pressure and fluid balance. It achieves this by binding to receptors that activate cyclic GMP (cGMP) production leading to vasodilation. ANP expression is mainly found in cardiac muscle cells but also detected in other tissues under certain conditions.
Biological function summary

These peptides contribute to renal sodium excretion commonly known as natriuresis and also promote diuresis which increases urine volume. ANP functions as a singular hormone without forming part of a complex. Beyond its role in cardiovascular and renal systems ANP influences lipid metabolism and adipocyte functions which may have implications for metabolic health.

Pathways

ANP is engaged in the natriuretic peptide signaling pathway which is important for cardiovascular homeostasis. Within this pathway related proteins include B-type Natriuretic Peptide (BNP) and C-type Natriuretic Peptide (CNP) all of which share similar receptor interactions through cGMP. Additionally ANP impacts the renin-angiotensin system (RAS) a significant hormonal system regulating blood pressure and fluid balance by counteracting the actions of angiotensin II.

ANP is notably associated with heart failure where its levels can indicate disease severity and prognosis. Elevated ANP levels have also been linked to hypertension contributing to diagnostic evaluations alongside other biomarkers like BNP. Both heart failure and hypertension involve complex interactions between ANP and proteins such as angiotensin II within their pathophysiological frameworks.

Target data

Atrial natriuretic peptide. Hormone that plays a key role in mediating cardio-renal homeostasis, and is involved in vascular remodeling and regulating energy metabolism (PubMed : 15741263, PubMed : 16875975, PubMed : 18835931, PubMed : 21672517, PubMed : 22307324, PubMed : 2532366, PubMed : 2825692, PubMed : 7595132, PubMed : 7720651, PubMed : 8087923, PubMed : 8653797). Acts by specifically binding and stimulating NPR1 to produce cGMP, which in turn activates effector proteins, such as PRKG1, that drive various biological responses (PubMed : 1660465, PubMed : 1672777, PubMed : 21098034, PubMed : 2162527, PubMed : 22307324, PubMed : 25401746, PubMed : 2825692, PubMed : 7720651, PubMed : 8384600, PubMed : 9893117). Regulates vasodilation, natriuresis, diuresis and aldosterone synthesis and is therefore essential for regulating blood pressure, controlling the extracellular fluid volume and maintaining the fluid-electrolyte balance (PubMed : 2532366, PubMed : 2825692, PubMed : 7595132, PubMed : 7720651, PubMed : 8087923, PubMed : 8653797). Also involved in inhibiting cardiac remodeling and cardiac hypertrophy by inducing cardiomyocyte apoptosis and attenuating the growth of cardiomyocytes and fibroblasts (PubMed : 16875975). Plays a role in female pregnancy by promoting trophoblast invasion and spiral artery remodeling in uterus, and thus prevents pregnancy-induced hypertension (By similarity). In adipose tissue, acts in various cGMP- and PKG-dependent pathways to regulate lipid metabolism and energy homeostasis (PubMed : 15741263, PubMed : 18835931, PubMed : 21672517, PubMed : 22307324). This includes up-regulating lipid metabolism and mitochondrial oxygen utilization by activating the AMP-activated protein kinase (AMPK), and increasing energy expenditure by acting via MAPK11 to promote the UCP1-dependent thermogenesis of brown adipose tissue (PubMed : 15741263, PubMed : 18835931, PubMed : 21672517, PubMed : 22307324). Binds the clearance receptor NPR3 which removes the hormone from circulation (PubMed : 1672777).. Long-acting natriuretic peptide. May have a role in cardio-renal homeostasis through regulation of natriuresis, diuresis, vasodilation, and inhibiting aldosterone synthesis (PubMed : 2532366, PubMed : 2825692, PubMed : 7595132, PubMed : 7955907, PubMed : 8087923, PubMed : 8653797). In vitro, promotes the production of cGMP and induces vasodilation (PubMed : 2825692). May promote natriuresis, at least in part, by enhancing prostaglandin E2 synthesis resulting in the inhibition of renal Na+-K+-ATPase (PubMed : 7720651). However reports on the involvement of this peptide in mammal blood volume and blood pressure homeostasis are conflicting; according to a report, in vivo it is not sufficient to activate cGMP and does not inhibit collecting duct transport nor effect diuresis and natriuresis (By similarity). Appears to bind to specific receptors that are distinct from the receptors bound by atrial natriuretic peptide and vessel dilator (PubMed : 2162527, PubMed : 2825692). Possibly enhances protein excretion in urine by decreasing proximal tubular protein reabsorption (PubMed : 11145122).. Vessel dilator. May have a role in cardio-renal homeostasis through regulation of natriuresis, diuresis, and vasodilation (PubMed : 2532366, PubMed : 7595132, PubMed : 7955907, PubMed : 8087923, PubMed : 8653797). In vitro, promotes the production of cGMP and induces vasodilation (PubMed : 2825692). May promote natriuresis, at least in part, by enhancing prostaglandin E2 synthesis resulting in the inhibition of renal Na+-K+-ATPase (PubMed : 7595132, PubMed : 7720651). However reports on the involvement of this peptide in mammal blood volume and blood pressure homeostasis are conflicting; according to a report it is not sufficient to activate cGMP and does not inhibit collecting duct transport nor effect diuresis and natriuresis (PubMed : 7831500). Appears to bind to specific receptors that are distinct from the receptors bound by the atrial natriuretic and long-acting natriuretic peptides (PubMed : 2162527, PubMed : 2825692). Possibly functions in protein excretion in urine by maintaining the integrity of the proximal tubules and enhancing protein excretion by decreasing proximal tubular protein reabsorption (PubMed : 11145122).. Kaliuretic peptide. May have a role in cardio-renal homeostasis through regulation of diuresis and inhibiting aldosterone synthesis (PubMed : 2825692, PubMed : 7595132, PubMed : 8087923). In vitro, promotes the production of cGMP and induces vasodilation (PubMed : 2825692). May promote natriuresis, at least in part, by enhancing prostaglandin E2 synthesis resulting in the inhibition of renal Na+-K+-ATPase (PubMed : 7595132, PubMed : 7720651). May have a role in potassium excretion but not sodium excretion (natriuresis) (PubMed : 8087923). Possibly enhances protein excretion in urine by decreasing proximal tubular protein reabsorption (PubMed : 11145122).. Urodilatin. Hormone produced in the kidneys that appears to be important for maintaining cardio-renal homeostasis (PubMed : 8351194, PubMed : 8779891, PubMed : 8853410). Mediates vasodilation, natriuresis and diuresis primarily in the renal system, in order to maintain the extracellular fluid volume and control the fluid-electrolyte balance (PubMed : 2528951, PubMed : 8351194, PubMed : 8779891, PubMed : 8853410). Specifically binds and stimulates cGMP production by renal transmembrane receptors, likely NPR1 (PubMed : 8384600, PubMed : 9893117). Urodilatin not ANP, may be the natriuretic peptide responsible for the regulation of sodium and water homeostasis in the kidney (PubMed : 8384600, PubMed : 8779891).. Auriculin-D. May have a role in cardio-renal homeostasis through regulation of natriuresis and vasodilation. In vivo promotes natriuresis and in vitro, vasodilates renal artery strips.. Auriculin-B. May have a role in cardio-renal homeostasis through regulation of natriuresis and vasodilation. In vivo promotes natriuresis and in vitro, vasodilates renal artery strips.. Auriculin-A. May have a role in cardio-renal homeostasis through regulation of regulation of natriuresis and vasodilation. In vivo promotes natriuresis. In vitro, vasodilates intestinal smooth muscle but not smooth muscle strips.. Atriopeptin-2. May have a role in cardio-renal homeostasis through regulation of natriuresis and vasodilation. In vivo promotes natriuresis. In vitro, selectively vasodilates intestinal and vascular smooth muscle strips.. Atriopeptin-1. May have a role in cardio-renal homeostasis through regulation of natriuresis and vasodilation. In vivo promotes natriuresis.
