Front Endocrinol (Lausanne). 2013 Oct 25;4:158. doi: 10.3389/fendo.2013.00158.

The brain renin-angiotensin system (RAS) has available the necessary functional components to produce the active ligands angiotensins II (AngII), angiotensin III, angiotensins (IV), angiotensin (1-7), and angiotensin (3-7). These ligands interact with several receptor proteins including AT1, AT2, AT4,...

Physiol Rep. 2013 Nov;1(6):e00151. doi: 10.1002/phy2.151. Epub 2013 Nov 13.

Angiotensin III (Ang III) has similar effects on blood pressure and aldosterone secretion as Ang II, but cardioprotective effects are also proposed. In this study, we investigated whether Ang III protects the heart against ischemia/reperfusion (I/R) injury. After sacrificing...

Glutamyl aminopeptidase (ENPEP) is a member of the M1 family of endopeptidases which are mammalian type II integral membrane zinc-containing endopeptidases. ENPEP is involved in the catabolic pathway of the renin-angiotensin system forming angiotensin III, which participates in blood...

OBJECTIVE: Angiotensin-III (Ang-III) is the downstream product of angiotensin-II (Ang-II) metabolized by aminopeptidase A (APA). At present, the research of Ang-III mainly concentrates on hypertension and the central renin-angiotensin system (RAS). However, few studies have focused on the relationship...

Capillary liquid chromatography interfaced to matrix-assisted laser desorption/ionization time-of-flight mass spectrometry using an on-line coupled piezoelectric flow-through microdispenser.

A piezoelectric flow-through microdispenser interfacing capillary liquid chromatography (LC) with matrix-assisted laser desorption/ionization time-of-fight mass spectrometry (MALDI-TOF MS) was developed for the identification of biomolecules. The MALDI target plate was placed on a computer controlled high-resolution x-y stage, on...

Practical considerations when using radio frequency-only quadrupole ion guide for atmospheric pressure ionization sources with time-of-flight mass spectrometry.

Construction details and performance evaluation of a radio frequency (rf)-only quadrupole ion guide for use with an electrospray ionization time-of-flight mass spectrometer is presented in this paper. Angiotensin III and cytochrome c were used in these experiments to investigate...

Role of aminopeptidases in the neuroendocrine control of blood pressure in experimental animals.

Control of blood pressure is partially accomplished by several proteolytic enzymes included in the renin-angiotensin system. These enzymes produce several peptides that form the active components of the system. Study of these enzymes is essential for a deep understanding...

Focus on Brain Angiotensin III and Aminopeptidase A in the Control of Hypertension.

The classic renin-angiotensin system (RAS) was initially described as a hormone system designed to mediate cardiovascular and body water regulation. The discovery of a brain RAS composed of the necessary functional components (angiotensinogen, peptidases, angiotensins, and specific receptor proteins)...

Distinct Molecular Effects of Angiotensin II and Angiotensin III in Rat Astrocytes.

It is postulated that central effects of angiotensin (Ang) II may be indirect due to rapid conversion to Ang III by aminopeptidase A (APA). Previously, we showed that Ang II and Ang III induced mitogen-activated protein (MAP) kinases ERK1/2...

Estrogen modulation of angiotensin-stimulated phosphoinositide hydrolysis in slices of rat anterior pituitary.

In this study, slices of rat anterior pituitary were prelabeled with [(3)H]myo-inositol and the ability of angiotensins II and III to stimulate [(3)H]phosphoinositide hydrolysis was characterized. When using tissue derived from ovariectomized rats, dose-response experiments revealed that angiotensin II...
