**Background of ANP Recombinant Protein**
Atrial Natriuretic Peptide (ANP), a 28-amino-acid hormone, is primarily synthesized and secreted by cardiac atrial myocytes in response to atrial stretching caused by increased blood volume. Discovered in the 1980s, ANP plays a pivotal role in regulating blood pressure, fluid balance, and cardiovascular homeostasis. It acts by binding to natriuretic peptide receptor-A (NPR-A), triggering cyclic GMP production, which promotes vasodilation, natriuresis (sodium excretion), and diuresis. These effects counterbalance the renin-angiotensin-aldosterone system (RAAS), making ANP a critical modulator of cardiovascular and renal functions.
The development of **ANP recombinant protein** stems from the need to harness its therapeutic potential. Native ANP has a short plasma half-life (<5 minutes) due to enzymatic degradation and renal clearance, limiting its clinical utility. Recombinant DNA technology enables large-scale production of stable, bioactive ANP analogs. By cloning the ANP gene into expression vectors (e.g., bacterial, yeast, or mammalian systems), followed by purification, recombinant ANP retains biological activity while offering scalability and consistency.
Clinically, recombinant ANP (e.g., carperitide) has been investigated for treating acute decompensated heart failure, hypertension, and renal disorders. It improves hemodynamics by reducing preload and afterload, enhancing cardiac output, and protecting against organ damage. Research also explores engineered ANP variants with prolonged half-life (e.g., PEGylation) or enhanced receptor affinity. Beyond therapeutics, recombinant ANP serves as a tool for studying natriuretic peptide signaling and drug discovery.
In summary, ANP recombinant protein represents a fusion of cardiovascular physiology and biotechnology, offering promising avenues for managing cardiorenal diseases and advancing molecular research.
