Both i.c.v. methoxamine (10 micrograms/kg) and phenylephrine (30 micrograms/kg) also increased plasma levels of arginine vasopressin (AVP) in LE rats from 2.6 +/- 0.4 (n = 9) to 22.4 +/- 3.5 (n = 6, P less than 0.01) and 37.0 +/- 4.0 pg/ml (n = 6, P less than 0.01), respectively, without affecting plasma renin activity (PRA) and plasma angiotensin II (ANG II) levels.

In our model, the role of renin I (prorenin) is to generate localized high concentrations of angiotensin II, eg, in the afferent arteriole of the kidney and in other vital organs, causing regional dilation by rendering tissues insensitive (tachyphylactic) to the vasoconstrictor effect of circulating angiotensin II or by releasing vasodilator substances.

This study suggests that the low renin state in DM may be explained by the enhanced inhibitory effect of ANG II and the resistance to the secretogogue actions of insulin and IGF-I.

In this study, the tissue-specific regulation of renin and angiotensinogen mRNA levels and the abundance of glomerular angiotensin II receptors were examined in male Sprague-Dawley rats (160 to 240 g) made diabetic with streptozotocin.

Similarly, ANG II (10(-8) mol/l) inhibition of renin was significantly enhanced in diabetic rats (P < 0.001).

Insulin reversed the inhibitory effects of ANG II on renin in normal rats, but it blunted the effect of ANG II in diabetic rats.

Evidence suggests that intrarenal RASs within glomeruli and proximal tubules may be activated with hyperglycemia, leading to stimulation of local ANG II production, which may exert feedback inhibition of systemic renin release.

|
Since renin catalyses the first and rate-limiting step of the renin-angiotensin system (RAS) cascade, interruption of the generation of angiotensin II (Ang II) by renin inhibitors at this highly specific initial step of the cascade has long been a therapeutic goal.

Due to the lack of effective alternative enzyme pathways, blockade of Ang II production may be more effective with renin inhibition than with angiotensin-converting enzyme (ACE) inhibition.

Plasma noradrenaline (NA, pmol/L), adrenaline (A, pmol/L), plasma renin activity (PRA, angiotensin I, nmol/L/h) and aldosterone (ALD, pmol/L) were measured in the supine position (baseline) and after 2, 5, and 20 min O in 10 healthy subjects (C), 9 T2D patients without AN (D), 14 T2D patients with AN and without PH (DAN), and 7 T2D patients with AN and PH (DAN-PH).

To explore the impact of angiotensin II on insulin signaling, NADPH oxidase-derived reactive oxygen species formation, vascular inflammation, apoptosis, and remodeling, we used transgenic TG(mRen2)27 (Ren2) rats, which harbor the mouse renin transgene and exhibits elevated tissue angiotensin II levels.

Angiotensin converting enzyme (ACE) is a key enzyme in the renin angiotensin system (RAS) and converts angiotensin (Ang) I to the vasoconstrictor Ang II, which is thought to be responsible for most of the physiological and pathophysiological effects of the RAS.

In the present study, we determined whether hyperglycemia activates the cardiac intracellular renin-Ang system (RAS) in vivo and whether ARBs, ACE, or renin inhibitors block synthesis and effects of intracellular Ang II (iAng II).

The renin-angiotensin system (RAS) can be inhibited through inhibition of angiotensin I (Ang I) generation from angiotensinogen by direct renin inhibitors, inhibition of angiotensin II (Ang II) generation from angiotensin I by angiotensin-converting enzyme inhibitors and finally by direct inhibition of the action of Ang II receptor level.

Ramipril decreased systolic and diastolic blood pressure, ACE activity, and angiotensin II and increased plasma renin activity.

Ang II type 1 receptor blockade with Olmesartan reduced CD renin to control levels but significantly increased juxtaglomerular renin.

Aliskiren, the first approved renin inhibitor to reach the market, is a low-molecular-weight, orally active, hydrophilic non-peptide molecule that blocks angiotensin I generation.

Baseline urinary angiotensinogen levels were positively correlated with renal angiotensinogen gene expression and AngII immunoreactivity but not with plasma renin activity or the urinary protein excretion rate.

These data show that: (1) HG increases AGT synthesis and activation of renin and ACE by MCTs, leading to local production of Ang I and Ang II. (2) Ang II activates endogenous AT1 and stimulates synthesis of VEGF. (3) HG activation of ERK starts within minutes and lasts for up to 24h.

Moreover, HG induced gene expression of angiotensinogen, renin, AT(1) R, and angiotensin II (Ang II) synthesis were inhibited by RAR? agonists and promoted by silencing RAR?.
|
25 |

|
Activation of RXR?, downregulated the expression of AT(1) R; and RXR? silencing accelerated HG induced expression of angiotensinogen and Ang II synthesis, whereas there was no significant effect on renin gene expression.

Exposure to high glucose resulted in a 2.1-fold increase ANG II levels mediated through increased renin activity, as exposure to high glucose increased renin levels and preincubation with Aliskiren abrogated glucose-induced ANG II production.

Renin exhibits profibrotic actions independent of angiotensin II, which is regulated by extracellular signal-regulated kinase 1 and 2 (ERK1/2).

In addition, high glucose stimulated angiotensinogen and renin expression, increased renin activity, and resulted in increased angiotensin II formation.

We used real-time polymerase chain reaction to detect mRNA expression of renin, angiotensinogen (AGT), angiotensin-converting enzyme (ACE), angiotensin II (Ang II) type 1 receptor (AT1), and Ang II type 2 receptor (AT2); western blot analysis for expression of ANG and AT1; and radioimmunoassay to measure Ang II production from MCs in the supernatants of culture media.

Direct renin inhibitors (DRIs) inhibit plasma renin activity (PRA), thereby preventing the conversion of angiotensinogen to angiotensin I; consequently, the levels of both Ang I and Ang II are reduced.

Urinary renin, therefore, more closely reflects renal RAAS activity than urinary angiotensinogen or aldosterone.
