Organic compounds containing the -CO-NH2 radical. Amides are derived from acids by replacement of -OH by -NH2 or from ammonia by the replacement of H by an acyl group. (From Grant & Hackh's Chemical Dictionary, 5th ed)
A response by the BARORECEPTORS to increased BLOOD PRESSURE. Increased pressure stretches BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.

Angiotensin receptor subtype 1 mediates angiotensin II enhancement of isoproterenol-induced cyclic AMP production in preglomerular microvascular smooth muscle cells. (1/154)

In a previous study, we found that angiotensin (Ang) II enhances beta-adrenoceptor-induced cAMP production in cultured preglomerular microvascular smooth muscle cells (PMVSMCs) obtained from spontaneously hypertensive rats. The purpose of the present investigation was to identify the Ang receptor subtypes that mediate this effect. In our first study, we compared the ability of Ang II, Ang III, Ang (3-8), and Ang (1-7) to increase cAMP production in isoproterenol (1 microM)-treated PMVSMCs. Each peptide was tested at 0.1, 1, 10, 100, and 1000 nM. Both Ang II and Ang III increased intracellular (EC50s, 1 and 11 nM, respectively) and extracellular (EC50s, 2 and 14 nM, respectively) cAMP levels in a concentration-dependent fashion. In contrast, Ang (3-8) and Ang (1-7) did not enhance either intracellular or extracellular cAMP levels at any concentration tested. In our second study, we examined the ability of L 158809 [a selective Ang receptor subtype 1 (AT1) receptor antagonist] to inhibit Ang II (100 nM) and Ang III (100 nM) enhancement of isoproterenol (1 microM)-induced cAMP production in PMVSMCs. L 158809 (10 nM) abolished or nearly abolished (p <.001) Ang II and Ang III enhancement of isoproterenol-induced intracellular and extracellular cAMP levels. In contrast, PD 123319 (300 nM; a selective AT2 receptor antagonist) did not significantly alter Ang II enhancement of isoproterenol-induced intracellular or extracellular cAMP levels. We conclude that AT1 receptors, but not AT2, Ang (3-8), nor Ang (1-7) receptors mediate Ang II and Ang III enhancement of beta-adrenoceptor-induced cAMP production in cultured PMVSMCs.  (+info)

Angiotensin II antagonist prevents electrical remodeling in atrial fibrillation. (2/154)

BACKGROUND: The blockade of angiotensin II (Ang II) formation has protective effects on cardiovascular tissue; however, the role of Ang II in atrial electrical remodeling is unknown. The purpose of this study was to investigate the effects of candesartan and captopril on atrial electrical remodeling. METHODS AND RESULTS: In 24 dogs, the atrial effective refractory period (AERP) was measured before, during, and after rapid atrial pacing. Rapid atrial pacing at 800 bpm was maintained for 180 minutes. The infusion of saline (n=8), candesartan (n=5), captopril (n=6), or Ang II (n=5) was initiated 30 minutes before rapid pacing and continued throughout the study. In the saline group, AERP was significantly shortened during rapid atrial pacing (from 149+/-11 to 132+/-16 ms, P<0.01). There was no significant difference in AERP shortening between the saline group and the Ang II group. However, in the candesartan and captopril groups, shortening of the AERP after rapid pacing was completely inhibited (from 142+/-9 to 147+/-12 ms with candesartan, from 153+/-15 to 153+/-14 ms with captopril, P=NS). Although rate adaptation of the AERP was lost in the saline group, this phenomenon was preserved in the candesartan and captopril groups. CONCLUSIONS: The inhibition of endogenous Ang II prevented AERP shortening during rapid atrial pacing. These results indicate for the first time that Ang II may be involved in the mechanism of atrial electrical remodeling and that the blockade of Ang II may lead to the better therapeutic management of human atrial fibrillation.  (+info)

Angiotensin II inhibits rat arterial KATP channels by inhibiting steady-state protein kinase A activity and activating protein kinase Ce. (3/154)

We used whole-cell patch clamp to investigate steady-state activation of ATP-sensitive K+ channels (KATP) of rat arterial smooth muscle by protein kinase A (PKA) and the pathway by which angiotensin II (Ang II) inhibits these channels. Rp-cAMPS, an inhibitor of PKA, did not affect KATP currents activated by pinacidil when the intracellular solution contained 0.1 mM ATP. However, when ATP was increased to 1.0 mM, inhibition of PKA reduced KATP current, while the phosphatase inhibitor calyculin A caused a small increase in current. Ang II (100 nM) inhibited KATP current activated by the K+ channel opener pinacidil. The degree of inhibition was greater with 1.0 mM than with 0.1 mM intracellular ATP. The effect of Ang II was abolished by the AT1 receptor antagonist losartan. The inhibition of KATP currents by Ang II was abolished by a combination of PKA inhibitor peptide 5-24 (5 microM) and PKC inhibitor peptide 19-27 (100 microM), while either alone caused only partial block of the effect. In the presence of PKA inhibitor peptide, the inhibitory effect of Ang II was unaffected by the PKC inhibitor Go 6976, which is selective for Ca2+-dependent isoforms of PKC, but was abolished by a selective peptide inhibitor of the translocation of the epsilon isoform of PKC. Our results indicate that KATP channels are activated by steady-state phosphorylation by PKA at normal intracellular ATP levels, and that Ang II inhibits the channels both through activation of PKCepsilon and inhibition of PKA.  (+info)

Reactive oxygen species-mediated homologous downregulation of angiotensin II type 1 receptor mRNA by angiotensin II. (4/154)

Recent studies suggest a crucial role of reactive oxygen species (ROS) for the signaling of angiotensin (Ang) II through Ang II type 1 receptor (AT(1)-R). However, the role of ROS in the regulation of AT(1)-R expression has not been explored. In this study, we examined the effect of an antioxidant on the homologous downregulation of AT(1)-R by Ang II. Ang II (10(-6) mol/L) decreased AT(1)-R mRNA with a peak suppression at 6 hours of stimulation in rat aortic vascular smooth muscle cells. Preincubation of vascular smooth muscle cells with N:-acetylcysteine (NAC), a potent antioxidant, almost completely inhibited the Ang II-induced downregulation of AT(1)-R mRNA. The effect of NAC was due to stabilization of the AT(1)-R mRNA that was destabilized by Ang II. The Ang II-induced AT(1)-R mRNA downregulation was also blocked by PD98059, an extracellular signal-regulated protein kinase (ERK) kinase inhibitor. Ang II-induced ERK activation was inhibited by NAC as well as by PD98059. Exogenous H(2)O(2) also suppressed AT(1)-R mRNA. These results suggest that the production of ROS and the activation of ERK are critical for the downregulation of AT(1)-R mRNA. The generation of ROS through stimulation of AT(1)-R not only mediates signaling of Ang II but also may play a crucial role in the adaptation process of AT(1)-R to the sustained stimulation of Ang II.  (+info)

Chronotropic effect of angiotensin II via type 2 receptors in rat brain neurons. (5/154)

Previously, we determined that angiotensin II (Ang II) elicits an Ang II type 2 (AT(2)) receptor-mediated increase of neuronal delayed rectifier K(+) (I(KV)) current in neuronal cultures from newborn rat hypothalamus and brain stem. This requires generation of lipoxygenase (LO) metabolites of arachidonic acid (AA) and activation of serine/threonine phosphatase type 2A (PP-2A). Enhancement of I(KV) results in a decrease in net inward current during the action potential (AP) upstroke as well as shortening of the refractory period, which may lead to alterations in neuronal firing rate. Thus, in the present study, we used whole-cell current clamp recording methods to investigate the AT(2) receptor-mediated effects of Ang II on the firing rate of cultured neurons from the hypothalamus and brain stem. At room temperature, these neurons exhibited spontaneous APs with an amplitude of 77.72 +/- 2.7 mV (n = 20) and they fired at a frequency of 0.8 +/- 0.1 Hz (n = 11). Most cells had a prolonged early after-depolarization that followed an initial fully developed AP. Superfusion of Ang II (100 nM) plus losartan (LOS, 1 microM) to block Ang II type 1 receptors elicited a significant chronotropic effect that was reversed by the AT(2) receptor inhibitor PD 123,319 (1 microM). LOS alone had no effect on any of the parameters measured. The chronotropic effect of Ang II was reversed by the general LO inhibitor 5,8,11,14-eicosatetraynoic acid (10 microM) or by the selective PP-2A inhibitor okadaic acid (1 nM) and was mimicked by the 12-LO metabolite of AA 12-(S)-hydroxy-(5Z, 8Z, 10E, 14Z)-eicosatetraynoic acid. These data indicate that Ang II elicits an AT(2) receptor-mediated increase in neuronal firing rate, an effect that involves generation of LO metabolites of AA and activation of PP-2A.  (+info)

Reversible renal impairment induced by treatment with the angiotensin II receptor antagonist candesartan in a patient with bilateral renal artery stenosis. (6/154)

BACKGROUND: It is well established that ACE-inhibitors should be avoided in patients with renal artery stenosis. In recent years it has also been recommended that caution should be demonstrated when angiotensin II blockers are used in the same type of patients but the evidence is based only on few cases. RESULTS: We describe a case where use of the angiotensin II antagonist candesartan (Atacand) induced renal failure in a patient with bilateral renal artery stenosis. The course of the case is enlighted by results from sequential renography, selective renal vein catheterisation for measurement of renin, and angiographic findings. CONCLUSIONS: In patients with renal artery stenosis the angiotensin II antagonist candesartan should be avoided.  (+info)

Use of positron emission tomography to study AT1 receptor regulation in vivo. (7/154)

Increased sodium intake and enhanced sodium sensitivity are implicated in the pathogenesis of hypertension and in the control of a major regulator of BP, the type 1 angiotensin receptor (AT(1) receptor). An in vivo technique to study changes of renal AT(1) receptors by dietary sodium was developed that uses positron emission tomography (PET). PET revealed that renal cortical AT(1) receptor binding was increased in sodium-loaded compared with sodium-deprived dogs, which correlated with ex vivo estimations of AT(1) receptor numbers. Plasma renin activity, angiotensin II, and aldosterone were inversely related to changes in AT(1) receptor binding. These results demonstrate, for the first time in vivo, that the renal AT(1) receptor is inversely related to the activity of the renin angiotensin system, which may provide a compensatory mechanism to prevent inappropriate fluctuations in arterial BP. The ability to measure AT(1) receptor binding in vivo has potential significance for clinical studies of AT(1) receptors, because PET is a noninvasive imaging technique that is readily applicable in humans.  (+info)

Angiotensin II type 1 and 2 receptors in conduit arteries of normal developing microswine. (8/154)

OBJECTIVE: To identify vascular cells capable of responding to angiotensin II (Ang II) generated in conduit arteries, we examined the Ang II type 1 receptor (AT1R) and Ang II type 2 receptor (AT2R) in the thoracic aorta (TA) and abdominal aorta (AA) and branches in 90-day fetal, 3-week postnatal, and 6-month adult microswine. METHODS AND RESULTS: By autoradiography ((125)I-[Sar(1)Ile(8)]-Ang II with or without AT1R- or AT2R-selective analogues or (125)I-CGP 42112), there were striking rostrocaudal differences in (1) AT2R binding at all ages (prominent in AA wall and branches, sparse in TA wall and branches) and (2) a non-AT2R binding site for CGP 42112 (consistently evident in postnatal TA and branches but absent in AA and branches). Furthermore, patterns of AT2R distribution in infradiaphragmatic arteries were developmentally distinct. In fetal AAs, high-density AT2Rs occupied the inner 60% of the medial-endothelial wall. In postnatal AAs, AT2Rs were sparse in the medial-endothelial wall but prominent in a circumferential smooth muscle alpha-actin-negative cell layer at the medial-adventitial border, occupying approximately 20% to 25% of the AA cross-sectional area. AT1R density in the TA and AA medial-endothelial wall increased with age, whereas AT2R density decreased after birth. CONCLUSIONS: A novel AT2R-positive cell layer confined to postnatal infradiaphragmatic arteries physically links adventitial and medial layers, appears optimally positioned to transduce AT2R-dependent functions of local Ang II, and suggests that adventitial Ang II may elicit regionally distinct vascular responses.  (+info)

The nucleus, being the largest sub-cellular compartment, varies in diameter from 10 to 20 micrometres. It is surrounded by a double membrane forming the nuclear envelope, about 30 nm wide. This selectively allows molecules to enter and leave the nucleus, and separates chemical reactions taking place in cytoplasm from reactions happening within the nucleus. The outer membrane has ribosomes. The inner and outer membrane fuse at regular spaces, forming nuclear pores. Similar to the cytoplasm of a cell, the nucleus contains nucleoplasm - a highly viscous solid containing the chromosomes and nucleoli. Chromosones contain information encoded in DNA attached to proteins called histones and are usually arranged in to a dense network called chromatin. Nucleoli are granular structures which make ribonucleic DNA (rDNA) and assemble it with proteins ...

Highly purified CD1-3-4-8- human thymocytes were obtained by panning techniques combined with cell depletion with antibody-coated magnetic beads. Most of these cells expressed cytoplasmic CD3 antigen, as assessed by mAbs known to react with the CD3 epsilon chain. After culture with low doses of PMA (0.5 ng/ml) and subsequent addition (at 24 h) of recombinant interleukin 2 (rIL-2; 100 U/ml) cells underwent extensive proliferation (40-60-fold of the initial cell input after 2 wk). The majority of the proliferating cells were CD3-TCR-. The remaining cells (5-40%) were represented by CD3+ TCR gamma/delta+ (BB3- A13+) cells. Further removal of CD3+ TCR-gamma/delta+ cells resulted in highly purified CD3- populations that further proliferated in culture with no substantial phenotypic changes. When CD3+ thymocytes were cultured under the same experimental conditions, only CD3+ TCR-alpha/beta+ cells could be detected, thus indicating that PMA did not affect the surface expression of the CD3/TCR complex, ...

Although angiotensin II type 1 receptor is well known and is involved in the vasoconstrictor and growth properties of angiotensin II, the role of the angiotensin II type 2 receptor (AT2R) remains much less understood. Although AT2R stimulation induces vasodilatation in normotensive rats, it induces vasoconstriction in pathological conditions involving oxidative stress and cyclooxygenase 2 expression. Thus, we studied ...

These studies demonstrate that RI Ang II, an AT2R ligand, does not induce a natriuresis in the presence of systemic AT1R blockade. However, a natriuretic response to Ang II, mediated by the AT2R, is unmasked by the intrarenal addition of PC-18, an APN inhibitor. Because the metabolism of Ang III to Ang IV by APN is inhibited by PC-18, these data suggest that Ang III is a significant mediator of Ang II-induced natriuresis. This conclusion is further supported by the ability of APA inhibition to abolish the natriuretic response to Ang II+PC-18.. Previous studies from our laboratory have shown that in the presence of AT1R blockade, RI Ang III infusion results in natriuresis that is abolished by concomitant PD infusion, implicating the renal AT2R in the response.21 Furthermore, addition of RI PC-18 to Ang III infusion causes a 1.8- to 2.8-fold increase in Na+ excretion compared with RI Ang III infusion alone.22 These findings prompted the present set of investigations to determine whether renal ...
