Azioni biochim/fisiol

Mca-APK(Dnp)-OH is a widely used fluorescent substrate for angiotensin-converting enzyme 2 (ACE2 cleaves between P & K). Proteolytic cleavage separates 7-methoxycoumarin-4-acetyl (Mca) from the fluorescence-quenching group 2,4-dinitrophenyl (Dnp), resulting in increased Mca fluorescence (Ex: 320-328 nm, Em: 405-420 nm). The fluorescence increase over background upon Mca-APK(Dnp) cleavage is more than 14-fold higher than that of Mca-YVADAPK(Dnp), while only Mca-YVADAPK(Dnp), but not Mca-APK(Dnp), can also be used for assessing caspase-1 (ICE) activity.

Pancreatic digestive enzymes present in meconium might be responsible for meconium-induced lung injury. The local Renin Angiotensin System plays an important role in lung injury and inflammation. Particularly, angiotensin converting enzyme-2 (ACE-2) has been identified as a protective lung enzyme against

ACE2 is a monocarboxypeptidase which generates Angiotensin (1-7) from Angiotensin II (1-8). Attempts to target the kidney Renin Angiotensin System using native ACE2 to treat kidney disease are hampered by its large molecular size, 100 kDa, which precludes its glomerular

We previously showed that 2 weeks of a severe food restricted (sFR) diet (40% of the caloric intake of the control (CT) diet) up-regulated the circulating renin angiotensin (Ang) system (RAS) in female Fischer rats, most likely as a result of

The kidney is an important target of the renin-ANG-aldosterone system (RAAS). To date, several studies have demonstrated the existence of a local RAAS in various tissues, including the renal tissue. The mineralocorticoid aldosterone is known to play a critical role

Autophagy exerts a dual role in promoting cell death or survival. Recent studies have shown that it may play an important role in lipopolysaccharide (LPS)-induced acute lung injury (ALI). It was also suggested that angiotensin converting enzyme 2 (ACE2) may
