Abstract
Chronic heart failure is a public health problem with a high prevalence worldwide and an important topic in clinical cardiology. Despite of advances in the drug treatment strategy for heart failure, the number of deaths from this condition continues to rise. It will be a renewed focus on preventing heart failure using proven and perhaps novel drugs. Management will also focus on comorbid conditions that may influence the progression of the disease. Traditional medicine has a potential to introduce different approaches for treatment of some disorders. We here reviewed top medicinal plants, according to traditional medicine to experimental studies, and their potency for the treatment of chronic heart failure based on the evidence of their functions.

Resveratrol improves cardiac function and left ventricular fibrosis after myocardial infarction in rats by inhibiting NLRP3 inflammasome activity and the TGF- β1/SMAD2 signaling pathway. PeerJ 2021; 9:e11501. [PMID: 34123595 PMCID: PMC8166236 DOI: 10.7717/peerj.11501] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Accepted: 05/02/2021] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Several studies have shown that resveratrol (RES), a naturally occurring polyphenol found in many plants, is beneficial for preventing cardiovascular diseases. However, the mechanism underlying the RES-mediated protection against myocardial infarction has not yet been revealed entirely. In this study, we investigated the protective effects of RES on cardiac function in a rat model of acute myocardial infarction (AMI) and the related underlying mechanisms. METHODS Male Sprague-Dawley rats were randomly divided into four groups: Sham (sham operation), Sham-RES, AMI (AMI induction), and AMI-RES. The rat AMI model was established by the permanent ligation of left anterior descending coronary artery method. The rats in the RES-treated groups were gavaged with RES (50 mg/kg/day) daily for 45 days after the Sham operation or AMI induction; rats in the Sham and AMI groups were gavaged with deionized water. Cardiac function was evaluated by echocardiography. Atrial interstitial fibrosis was assessed by hematoxylin-eosin or Masson's trichrome staining. Real-time PCR and western blotting analyses were performed to examine the levels of signaling pathway components. RESULTS RES supplementation decreased the inflammatory cytokine levels, improved the cardiac function, and ameliorated atrial interstitial fibrosis in the rats with AMI. Furthermore, RES supplementation inhibited NLRP3 inflammasome activity, decreased the TGF-β1 production, and downregulated the p-SMAD2/SMAD2 expression in the heart. CONCLUSION RES shows notable cardioprotective effects in a rat model of AMI; the possible mechanisms underlying these effects may involve the improvement of cardiac function and atrial interstitial fibrosis via the RES-mediated suppression of NLRP3 inflammasome activity and inhibition of the TGF-β1/SMAD2 signaling pathway in the heart.

Abstract
Quercetin has attracted more attention in recent years due to its protective role against ischemia/reperfusion injury. Quercetin can alleviate oxidative stress injury through the inhibition of NADPH oxidase and xanthine oxidase, blockage of the Fenton reaction, and scavenging of reactive oxygen species. Quercetin can also exert anti-inflammatory and anti-apoptotic effects by reducing the response to inflammatory factors and inhibiting cell apoptosis. Moreover, it can induce vasodilation effects through the inhibition of endothelin-1 receptors, the enhancement of NO stimulation and the activation of the large-conductance calcium-activated potassium channels. Finally, Quercetin can also antagonize the calcium overload. These multifaceted activities of Quercetin make it a potential therapeutic alternative for the treatment of ischemia/reperfusion injury.

Abstract
A particularly phenolic-rich fraction extracted from red wine from the São Francisco valley (Northeastern Brazil) was chemically characterized and its hypotensive and antioxidant effects on spontaneously hypertensive rats were studied both in vitro and in vivo. The liquid-liquid pH dependent fractionation scheme afforded a fraction with high content of bioactive phenolics such as flavonols, flavonol glycosides, phenolic acids and anthocyanins, whose identities were confirmed by liquid chromatography coupled to mass spectrometry analysis. Pretreatment of spontaneously hypertensive rats with this wine fraction at doses of 50 and 100 mg/kg by gavage for 15 days was able to decrease mean arterial pressure and heart rate as well as decrease serum lipid peroxidation. The fraction at concentrations of 0.01–1000 µg/mL induced concentration-dependent relaxation of isolated rat superior mesenteric artery rings pre-contracted with phenylephrine and this effect was not attenuated by endothelium removal. Our results demonstrate it is possible for phenolic constituents of red wine that are orally bioavailable to exert in vivo hypotensive and antioxidant effects on intact endothelial function.

Abstract
Due to the association between inflammation and endothelial dysfunction in atherosclerosis, the blockage of the inflammatory process that occurs on the endothelial cells may be a useful way of preventing atherosclerosis. In the present study, human umbilical vein endothelial cells (HUVECs) were used to investigate the protective effects of quercetin and taraxasterol against H2O2-induced oxidative damage and inflammation. HUVECs were pretreated with quercetin or taraxasterol at concentrations ranging between 0 and 210 µM for 12 h, prior to being administered different concentrations of H2O2 for 4 h. Cell viability and levels of apoptosis were assessed through cell counting kit-8 (CCK-8) and terminal deoxynucleotidyl transferase dUTP nick end labeling assays, respectively, to determine the injury to the HUVECs. The viability loss in the H2O2-induced HUVECs was markedly restored in a concentration-dependent manner by pretreatment with quercetin or taraxasterol. This effect was accompanied by significantly decreased expression of vascular cell adhesion molecule 1 (VCAM-1) and cluster of differentiation (CD)80 for taraxasterol and that of CD80 for quercetin. In conclusion, the present study showed the protective effects of quercetin and taraxasterol against cell injury and inflammation in HUVECs and indicated that the effects were mediated via the downregulation of VCAM-1 and CD80 expression. This study has therefore served as a preliminary investigation on the anti-atherosclerotic and cardiovascular protective effects of quercetin and taraxasterol as dietary supplements.

Quercetin improves postischemic recovery of heart function in doxorubicin-treated rats and prevents doxorubicin-induced matrix metalloproteinase-2 activation and apoptosis induction. Int J Mol Sci 2015; 16:8168-85.

Abstract
Quercetin (QCT) is flavonoid that possesses various biological functions including anti-oxidative and radical-scavenging activities. Moreover, QCT exerts some preventive actions in treatment of cardiovascular diseases. The aim of present study was to explore effects of prolonged administration of QCT on changes induced by repeated application of doxorubicin (DOX) in rat hearts. We focused on the ultrastructure of myocardium, matrix metalloproteinases (MMPs), biometric parameters, and apoptosis induction. Our aim was also to examine effects of QCT on ischemic tolerance in hearts exposed to chronic effects of DOX, and to determine possible mechanisms underlying effects of QCT. Our results showed that QCT prevented several negative chronic effects of DOX: (I) reversed DOX-induced blood pressure increase; (II) mediated improvement of deleterious effects of DOX on ultrastructure of left ventricle; (III) prevented DOX-induced effects on tissue MMP-2 activation; and (iv) reversed effects of DOX on apoptosis induction and superoxide dismutase inhibition. Moreover, we showed that rat hearts exposed to effects of QCT were more resistant to ischemia/reperfusion injury. Effects of QCT on modulation of ischemic tolerance were linked to Akt kinase activation and connexin-43 up-regulation. Taken together, these results demonstrate that prolonged treatment with QCT prevented negative chronic effects of DOX on blood pressure, cellular damage, MMP-2 activation, and apoptosis induction. Moreover, QCT influenced myocardial responses to acute ischemic stress. These facts bring new insights into mechanisms of QCT action on rat hearts exposed to the chronic effects of DOX.

Abstract
Background Dietary quercetin improves cardiovascular health, relaxes some vascular smooth muscle and has been demonstrated to serve as a substrate for the cyclooxygenase enzyme. Aims 1. To test quantitatively a potential direct vasodilatory effect on intramural coronary resistance artery segments, in different concentrations. 2. To scale vasorelaxation at different intraluminal pressure loads on such vessels of different size. 3. To test the potential role of prostanoids in vasodilatation induced by quercetin. Methods Coronary arterioles (70–240 µm) were prepared from 24 rats and pressurized in PSS, using a pressure microangiometer. Results The spontaneous tone that developed at 50 mmHg was relaxed by quercetin in the 10−9 moles/lit concentration (p<0.05), while 10−5 moles/lit caused full relaxation. Significant relaxation was observed at all pressure levels (10–100 mmHg) at 10−7 moles/lit concentration of quercetin. The cyclooxygenase blocker indomethacin (10−5moles/lit) induced no relaxation but contraction when physiological concentrations of quercetin were present in the tissue bath (p<0.02 with Anova), this contraction being more prominent in smaller vessels and in the higher pressure range (p<0.05, Pearson correlation). A further 2–8% contraction could be elicited by the NO blocker L-NAME (10−4 moles/lit). Conclusion These results demonstrate that circulating levels of quercetin (10−7 moles/lit) exhibit a substantial coronary vasodilatory effect. The extent of it is commeasurable with that of several other physiological mechanisms of coronary blood flow control. At least part of this relaxation is the result of an altered balance toward the production of endogenous vasodilatory prostanoids in the coronary arteriole wall.

Abstract
Alcohol is a commonly used drug worldwide. Epidemiological studies have identified alcohol consumption as a factor that may either positively or negatively influence many diseases including cardiovascular disease, certain cancers and dementia. Often there seems to be a differential effect of various drinking patterns, with frequent moderate consumption of alcohol being salutary and binge drinking or chronic abuse being deleterious to one’s health. A better understanding of the cellular and molecular mechanisms mediating the many effects of alcohol consumption is beginning to emerge, as well as a clearer picture as to whether these effects are due to the direct actions of alcohol itself, or caused in part by its metabolites, e.g., acetaldehyde, or by incidental components present in the alcoholic beverage (e.g., polyphenols in red wine). This review will discuss evidence to date as to how alcohol (ethanol) might affect atherosclerosis that underlies cardiovascular and cerebrovascular disease, and the putative mechanisms involved, focusing on vascular endothelial and smooth muscle cell effects.

Abstract
Epidemiological studies beginning in the 1990s have reported that intake of quercetin, a polyphenolic flavonoid found in a wide variety of plant-based foods, such as apples, onions, berries, and red wine, is inversely related to cardiovascular disease. More recent work using hypertensive animals and humans (>140 mm Hg systolic and >90 mm Hg diastolic) indicates a decrease in blood pressure after quercetin supplementation. A number of proposed mechanisms may be responsible for the observed blood pressure decrease such as antioxidant effects, inhibition of angiotensin-converting enzyme activity, and improved endothelium-dependent and -independent function. The majority of these mechanisms have been identified using animal models treated with quercetin, and relatively few have been corroborated in human studies. The purpose of this review is to examine the evidence supporting the role of quercetin as a potential therapeutic agent and the mechanisms by which quercetin might exert its blood pressure-lowering effect.

Abstract
AIM OF THE STUDY Vessel endothelium injury caused by reactive oxygen species (ROS) including H(2)O(2) plays a critical role in the pathogenesis of cardiovascular disorders. Therefore, agents or antioxidants that can inhibit production of ROS has highly clinical values in cardiovascular therapy. Curculigoside is the major bioactive compounds present in Curculigo orchioides, and possess potent antioxidant properties against oxidative stress insults through undefined mechanism(s). The present study was designed to test the hypothesis that curculigoside can inhibit H(2)O(2)-induced injury in human umbilical vein endothelial cells. MATERIALS AND METHODS Human umbilical vein endothelial cells (HUVECs) were treated with curculigoside in the presence/absence of hydrogen peroxide (H(2)O(2)). The protective effects of curculigoside OP-D against H(2)O(2) were evaluated. RESULTS HUVECs incubated with 400 μM H(2)O(2) had significantly decreased the viability of endothelial cells, which was accompanied with apparent cells apoptosis, the activation of caspase-3 and the upregulation of p53 mRNA expression. In addition, H(2)O(2) treatment induced a marked increase of MDA, LDH content and in intracellular ROS, decreased the content of nitric oxide (NO) and GSH-Px activities in endothelial cells. However, pretreatment with 0.5.5,10 μM curculigoside resulted in a significant recovery from H(2)O(2)-induced cell apoptosis. Also, it decreased other H(2)O(2)-induced damages in a concentration-dependent manner. Furthermore, pretreatment with curculigoside decreased the activity of caspase-3 and p53 mRNA expression, which was known to play a key role in H(2)O(2)-induced cell apoptosis. CONCLUSION The present study shows that curculigoside can protect endothelial cells against oxidative injury induced by H(2)O(2), suggesting that this compound may constitute a promising intervention against cardiovascular disorders.

Abstract
AIMS It has been reported that imbibing red wine increases coronary blood flow reserve acutely. In the absence of changes in coronary driving pressure, any increases in coronary blood flow reserve should occur through a decrease in capillary resistance, which in turn is determined by capillary dimensions and whole-blood viscosity. Since alcohol intake is unlikely to acutely change capillary dimensions, we hypothesized that it must increase coronary blood flow reserve by reducing whole-blood viscosity. METHODS AND RESULTS Forty-five normal subjects were randomly assigned to water (n = 12), vodka (n = 11), white wine (n = 11), and red wine (n = 11). Myocardial blood flow reserve was measured at baseline and after up to 2 weeks of beverage consumption using myocardial contrast echocardiography. In addition, whole-blood viscosity and its principal determinants (haematocrit; erythrocyte deformability, mobility, and charge; plasma fibrinogen; and total serum protein, glucose, and lipids) were also measured. Systolic and diastolic blood pressure and heart rate did not change between the two examinations either at rest or following dipyridamole infusion. Neither did myocardial blood flow reserve nor whole-blood viscosity or any of its determinants. Only high-density lipoprotein-2 increased for all alcohol consumers (12.4 +/- 5.3 vs. 10.9 +/- 4.7, P = 0.007). CONCLUSION It is concluded that modest alcohol consumption for up to 2 weeks does not increase myocardial blood flow reserve. It also does not alter whole-blood viscosity or any of its principal determinants. Therefore, the beneficial cardiovascular effects of modest alcohol consumption over 1-2 weeks cannot be attributed either to its effect on the coronary microcirculation or haemorheology.

Abstract
Quercetin is a polyphenolic flavonoid. Common sources in the diet are apples, onions, berries, and red wine. Epidemiological studies have found an inverse relationship between dietary quercetin intake and cardiovascular disease. This has led to in vitro, in vivo, and clinical research to determine the mechanism by which quercetin exerts cardio-protective effects. Recent studies have found a reduction in blood pressure when hypertensive (>140 mm Hg systolic and >90 mm Hg diastolic) animals and humans are supplemented with quercetin. Proposed mechanisms for the antihypertensive effect of quercetin include decreased oxidative stress, inhibition of angiotensin converting enzyme activity, improved endothelial function, direct action on the vascular smooth muscle, and/or modulation in cell signaling and gene expression. Although in vitro and in vivo evidence exists to support and refute each possibility, it is likely that quercetin influences multiple targets via a combination of known and as yet undiscovered mechanisms. The purpose of this review is to examine the mechanisms whereby quercetin might reduce blood pressure in hypertensive individuals.

Abstract
Endothelial dysfunction is an early pathophysiological feature and independent predictor of poor prognosis in most forms of cardiovascular diseases. Epidemiological studies report an inverse association between dietary flavonoid consumption and mortality from cardiovascular diseases. In the present paper, we review the effects of flavonoids, especially quercetin and wine polyphenols, on endothelial function and dysfunction and its potential protective role in hypertension, ischemic heart disease and stroke. In vitro studies show that flavonoids may exert multiple actions on the NO-guanylyl cyclase pathway, endothelium-derived hyperpolarizing factor(s) and endothelin-1 and protect endothelial cells against apoptosis. In vivo, flavonoids prevent endothelial dysfunction and reduce blood pressure, oxidative stress and end-organ damage in hypertensive animals. Moreover, some clinical studies have shown that flavonoid-rich foods can improve endothelial function in patients with hypertension and ischemic heart disease. Altogether, the available evidence indicates that quercetin and wine polyphenols might be of therapeutic benefit in cardiovascular diseases even though prospective controlled clinical studies are still lacking.

Abstract
The reduction in coronary heart disease (CHD) from moderate alcohol intake may be mediated, in part, by increased fibrinolysis; endothelial cell (EC)-mediated fibrinolysis should decrease acute atherothrombotic consequences (eg, plaque rupture) of myocardial infarction (MI). We have shown that alcohol and individual polyphenols modulate EC fibrinolytic protein (t-PA, u-PA, PAI-1, u-PAR and Annexin-II) expression at the cellular, molecular, and gene levels to sustain increased fibrinolytic activity. Herein we describe the sequence of molecular events by which EC t-PA expression is increased through common activation of p38 MAPK signaling. Up-regulation of t-PA gene transcription, through specific alcohol and polyphenol transcription factor binding sites in the t-PA promoter, results in increased in vitro fibrinolysis and in vivo clot lytic activity (using real-time fluorescence [Fl] imaging of Cy5.5-labeled fibrin clot lysis in a mouse model). Fl-labeled fibrin clots injected into untreated C56Bl/6 wild-type control mice are lysed in approximately 2 hours and clot lytic rates significantly increased in mice treated with either alcohol, catechins, or quercetin (4-6 weeks). Fl-labeled clot lysis in ApoE knock-out mice (atherosclerosis model) showed impaired in vivo clot lysis that was "normalized" to wild-type control levels by treatment with alcohol, catechin, or quercetin for 6 to 8 weeks.

Abstract
By using red wine (RW), dealcoholized red wine (DARW), polyphenols-stripped red wine (PSRW), ethanol-water solution (ET), and water (W), the role of wine polyphenols, ethanol, and urate on vascular function was examined in humans (n = 9 per beverage) and on isolated rat aortic rings (n = 9). Healthy males randomly consumed each beverage in a cross-over design. Plasma ethanol, catechin, and urate concentrations were measured before and 30, 60 and 120 minutes after beverage intake. Endothelial function was assessed before and 60 minutes after beverage consumption by normalized flow-mediated dilation (FMD). RW and DARW induced similar vasodilatation in the isolated vessels whereas PSRW, ET, and W did not. All ethanol-containing beverages induced similar basal vasodilatation of brachial artery. Only intake of RW resulted in enhancement of endothelial response, despite similar plasma catechin concentration after DARW. The borderline effect of RW on FMD (P = 0.0531) became significant after FMD normalization (P = 0.0043) that neutralized blunting effect of ethanol-induced basal vasodilatation. Effects of PSRW and ET did not differ although plasma urate increased after PSRW and not after ET, indicating lack of urate influence on endothelial response. Acute vascular effects of RW, mediated by polyphenols, cannot be predicted by plasma catechin concentration only.

Abstract
In the current study, seven Styrian white wine varieties, as well as their corresponding grape skin extracts (GSE), were tested for possible antagonistic effects on several endogenous vasoconstrictors known to be involved in the pathogenesis of cardiovascular diseases via tissue contraction experiments. Results were compared to those of Zweigelt, the most cultivated Styrian red wine. Bovine coronary artery strips were attached to a force transducer connected to a bridge amplifier, and isometric force was recorded on a multipen recorder. Preincubation of the vessels with the dealcoholized wines (DAW; 330 microl/ml) inhibited the constrictions to histamine and serotonin (5-HT) NO-dependently in the range of 5-80% and 30-90%, respectively (Zweigelt 47% and 90%, respectively). The corresponding GSE (20 mg/ml) inhibited the coronary constrictions to histamine in the range of 40% to 80% (Zweigelt 80%). Additionally, all DAW antagonized the contractile responses to the thromboxane-mimetic U46619 and the isoprostane 8-iso-PGF2alpha, indicating a nonspecific inhibition. To characterize the vasoactive component(s), the Traminer GSE was separated representatively using ultrafiltration, solid phase extraction (SPE) on Isolute C18(EC), and Isolute SCX-2, as well as column chromatography (CC) on polyamide. The resulting fractions were subsequently bioassayed for vasorelaxing activity. Preliminary results refer to a very hydrophilic, nonpolyphenolic basic compound with a MW<1000 Da. Our findings demonstrate that certain Styrian wines have remarkable antagonistic effects on several endogenous agonists in vitro, and that also nonpolyphenolic components in grapes may contribute to cardiovascular protection. Further separation steps as well as phytochemical and pharmacological investigations are in progress.

Abstract
The mechanisms involved in the cardioprotector effect of red wine have not yet been completely elucidated but probably an endothelium-dependent vasodilator action may play a significant role in this effect. Experiments were undertaken to determine whether a Brazilian red wine (BRW) induces vasodilation in the mesenteric vascular bed (MVB) and an antihypertensive effect was also assessed in rats with NO-deficient hypertension. In MVB precontracted with norepinephrine, BRW (alcohol-free lyophilized) induces a long-lasting endothelium-dependent vasodilation that is not reduced by indomethacin. Inhibition of NO-synthase by NG-nitro-L-arginine methyl ester (L-NAME) and guanylyl cyclase by 1H-[1,2,3] oxadiazolo [4,4-a]quinoxalin-1-one (ODQ) reduces the vasodilator effect of BRW. In vessels precontracted with norepinephrine and depolarized with KCl (25 Mm) or treated with Ca-dependent K channel blockers charybdotoxin (ChTx) plus apamin, the effect of BRW was significantly reduced. However, this effect is not affected by ATP-dependent K (KATP) channel blocker (glibenclamide). The residual vasodilator effect of BRW observed in vessels pretreated with ChTx plus apamin is completely abolished by ChTx plus apamin plus L-NAME. Concentrations of atropine, pyrilamine, yohimbine, and HOE 140 that significantly reduced the vasodilator effect of acetylcholine, histamine, clonidine, and bradykinin, respectively did not change the vasodilator effect of BRW. Chronic oral administration of BRW induced a significant reduction in systolic, mean and diastolic arterial pressure in rats with L-NAME hypertension. The present results demonstrated that vasodilator effect of BRW is dependent on endothelium-derived hyperpolarizing factor (EDHF) in combination with nitric oxide (NO). The antihypertensive effect of red wine demonstrated in the present study may play a significant role on the cardioprotective action of chronic red wine consumption.

Abstract
Flavonoids are known to relax isolated large arteries, but the cardiovascular actions of flavonoids are not well studied in vivo. Hence, we determined the systemic and regional haemodynamic responses to a novel synthetic flavonol, 3',4'-dihydroxyflavonol (DiOHF), in conscious sheep previously instrumented with flow probes on the aorta and coronary, mesenteric, renal, and iliac arteries. Intravenous injection of DiOHF (1.0 mg/kg) caused a delayed but prolonged vasodilatation in the coronary and renal vascular beds, with no changes in the mesenteric or iliac vascular beds. DiOHF induced prolonged increases in heart rate and cardiac output without altering arterial pressure. Pretreatment with Nomega-nitro-L-arginine, a nonspecific inhibitor of nitric oxide synthase, abolished all the cardiovascular effects of DiOHF. The results indicate that DiOHF caused a nitric oxide-dependent vasodilatation of the coronary and renal vasculature and an increase in cardiac output due to its chronotropic action.

Abstract
Cumulative evidence suggests that moderate wine consumption exerts a cardioprotective effect. We investigated the occurrence of an antihypertensive effect of an alcohol-free hydroalcoholic grape skin extract (GSE) obtained from skins of a vinifera grape (Vitis labrusca) in experimental rodent hypertension models. The vasodilator effect of GSE (polyphenols concentration 55.5 mg g(-1)) was also assessed in the isolated mesenteric vascular bed of Wistar rats and the antioxidant effect was studied on lipid peroxidation of hepatic microsomes. Oral administration of GSE significantly reduced systolic, mean and diastolic arterial pressure in Wistar rats with desoxycorticosterone acetate-salt and N(G)-nitro-L-arginine methyl ester (L-NAME) induced experimental hypertension. In the rat isolated mesenteric vascular bed pre-contracted with norepinephrine, bolus injections of GSE induced endothelium-dependent vasodilatation that was substantially inhibited by L-NAME, but not by indometacin, tetraethylammonium or glibenclamide. Lipid peroxidation of hepatic microsomes estimated as malondialdehyde production was concentration-dependently inhibited by GSE. In conclusion, the antihypertensive effect of GSE might be owing to a combination of vasodilator and antioxidant actions of GSE. These findings also suggest that the beneficial effect of moderate red wine consumption could be owing to an antihypertensive action induced by compounds occurring in the skin of vinifera grapes.

Abstract
Resveratrol (RSV) has been suggested to have cancer preventive properties, on the basis that it suppresses proliferation and induces apoptosis in various tumor cells. Here we test its cytostatic effects on peripheral blood human lymphocytes. RSV (up to 50 microM) had no detectable effects on resting lymphocytes. With the mitogen phytohemagglutin (PHA), however, RSV elicited concentration- and time-dependent responses in lymphocytes. RSV (>/=50 microM) prevented cell entry into the cell cycle, resulting in 99% suppression at 100 microM. The arrested lymphocytes following 24h treatment with 50 microM RSV had minimal RNA content, the feature characteristic of G(0) cells, and were blocked at the stage past the induction of cyclins D2 and D3 and prior to induction of cyclin E. Prolonged treatment (72h) of PHA-stimulated lymphocytes with 100 microM RSV showed a pronounced decrease in the expression of pRb, cyclins E and B, and reduction in p34cdc2 and PCNA. The activation-induced apoptosis was also reduced in the presence of >/=50 microM RSV. These data suggest that studies designed to test RSV efficacy as a chemopreventive agent should include evaluation of its immunomodulatory effect revealed by suppression of lymphocyte stimulation as well as its effect on apoptosis of stimulated lymphocytes.
