Background: Angiotensinogen (AGT) is the primary precursor of angiotensins, peptide hormones that play a central role in the renin-angiotensin system (RAS) (1-3). AGT is a secreted protein synthesized primarily by the liver and secreted into circulation. Upon binding to renin, the amino terminal fragment of AGT is cleaved and released as a decapeptide hormone termed angiotensin 1 (Ang I). Ang I is subsequently processed by angiotensin converting enzyme (ACE) to generate angiotensin II (Ang II), which acts on AT1 and AT2 receptors in the central nervous system to increase production of anti-diuretic hormone (ADH), while promoting vasoconstriction in the peripheral circulation (4). Aberrant upregulation of Ang II has been associated with numerous clinical conditions, including hypertension, atherosclerosis, myocardial hypertrophy, and obesity (5-7). Alternative cleavage products of Ang I (e.g., Ang 1-7) can also be generated by ACE2 cleavage, some of which display biological functions that are distinct from Ang II (8). Treatments that target the RAS (e.g., ACE inhibitors) are consequently of significant importance in the treatment of hypertensive and hypertensive-related disorders(5-8).

Background: ACE2 is a carboxypeptidase that catalyses the conversion of angiotensin I to angiotensin 1-9, or of angiotensin II to the vasodilator angiotensin 1-7 (1). ACE2 is a critical component in the renin-angiotensin system (RAS). ACE2 is predominantly expressed in vascular endothelial cells of the heart and kidney and Leydig and Sertoli cells of the testis (2,3). The unique expression pattern of ACE2 determines its essential role in the regulation of cardiovascular and kidney functions, as well as fertility. ACE2 protein is localized mainly in the extracellular space with its carboxy terminal end attached to the membrane via its transmembrane domain. Active ACE2 enzyme is secreted by cleavage at the amino terminus. Research studies have shown that ACE2 expression is elevated in human failing heart (4). ACE2 is also a functional receptor for SARS coronavirus (SARS-CoV) (5).

Background: Renin is a secreted proteinase whose enzymatic activity is to convert angiotensinogen into angiotensin I in the plasma, initiating a process that results in an elevation of blood pressure and increased sodium retention by the kidney (1). Renin is synthezed in kidney as a procursor, prorenin, which is released into circulation. Both renin and prorenin can bind to (pro)renin receptor and induce angiotensin-independent signaling events leading to activation of MAPKs and up-regulation of TGF-β1 and matrix proteins (2, 3). Defects in renin can cause renal tubular dysgenesis, a severe autosomal recessive disorder of renal tubular development (4, 5).
