Abstract
Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) are life-threatening condition in critically ill patients. Resveratrol (Res), a natural polyphenol, has therapeutic effect in animal model with ALI; however, whether Res attenuates ALI through modulation of macrophage phenotypes in the animal model remains unknown. We in this study treated LPS-induced murine ALI with 30 mg/kg Res and observed significantly reduced severity of ALI in the Res-treated mice 48 hours after Res treatment. Neutrophil infiltrates were significantly reduced, accompanied with lower infiltration of CD45+ Siglec F- phenotype macrophages, but higher population of CD45+ Siglec F+ and CD45+ CD206+ alternatively activated macrophages (M2 cells) in the Res-treated mice with ALI. In addition, the expression of IL-1beta and CXCL15 cytokines was suppressed in the treated mice. However, Res treatment in mice with myeloid cell-restricted SOCS3 deficiency did not significantly attenuate ALI severity and failed to increase population of both CD45+ Siglec F+ and CD45+ CD206+ M2 subtype macrophages in the murine ALI. Further studies in wild-type macrophages revealed that Res treatment effectively reduced the expression of IL-6 and CXCL15, and increased the expression of arginase-1, SIRT1 and SOCS3. However, macrophages' lack of SOCS3 expression were resistant to the Res-induced suppression of IL-6 and CXCL15 in vitro. Thus, we conclude that Res suppressed CD45+ Siglec F- and CD45+ CD206- M1 subtype macrophages through SOCS3 signalling in the LPS-induced murine ALI.

Imaging Flow Cytometric Analysis of Stilbene-Dependent Apoptosis in Drug Resistant Human Leukemic Cell Lines. Molecules 2019; 24:molecules24101896. [PMID: 31108853 PMCID: PMC6571880 DOI: 10.3390/molecules24101896] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2019] [Revised: 05/03/2019] [Accepted: 05/16/2019] [Indexed: 01/08/2023] Open
Abstract
Background: The natural compounds have been researched extensively as an alternative to the conventional chemotherapy and radiation. Stilbene derivatives appear as a group of therapeutics which deserves special attention. The present study was designed to analyze the effects of stilbene derivatives on drug resistant human leukemic cells. The aim of this work was to evaluate the apoptotic effect of stilbene derivatives in various concentrations on leukemic cells (LC) with and without resistant phenotype. Methods: Human acute promyelocytic leukemia (APL) cell lines (HL60, HL60/MX1, HL60/MX2) and acute lymphoblastic leukemia (ALL) cell lines (CEM/C1, CCRF-CEM) were studied. T-resveratrol, piceatannol, rhaponticin, deoxyrhaponticin, pterostilbene were used to stimulate apoptosis. Mitoxantrone (MIT) was applied to induce drug resistance. Results: t-Resveratrol (RES), deoxyrhaponticin (D-RHAP), rhaponticin (RHAP), pterostilbene (PTER), and piceatannol (PIC) influenced viability and induced apoptosis in all investigated cell lines. Conclusions: Our results confirmed that RES, PIC, RHAP, D-RHAP, and PTER are essential therapeutic compounds with anticancer activity exhibited by induction of apoptosis in leukemic cells with and without resistant phenotype. Stilbene-induced apoptosis in HL60/MX1, HL60/MX2, CEM/C1, and CCRF-CEM leukemia cell lines have been presented in very few studies so far and our research is an important contribution to the investigation of these substances.

Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) is characterized by excessive accumulation of lymphoblast and progenitors. Leukemia is the most common cancer in children and ALL is the most common subtype. Many studies have shown that the YKL-40 gene is one of the most widely expressed genes in tumors, including leukemia, but not in healthy blood cells. Clinical studies have shown that serum YKL-40 levels have a positive correlation with tumor expansion, in addition to being a prognostic agent independent of a short relapse-free interval, as well as a brief overall survival in patients with various cancers. The previous study shows that YKL-40 is closely related to the degree of pathology or degree of human leukemia pathology and plays an important role in cell proliferation. Hence, the YKL-40 can be an attractive target in designing anticancer therapies. METHODS CCRF-CEM cells were treated with resveratrol and prednisolone. For analysis of YKL-40 expression changes under medication, real-time polymerase chain reaction (PCR) and Western blot techniques were used at resonating intervals of 24 and 48 hours. RESULTS The effect of 15, 50, and 100 μM resveratrol and 700 μM of prednisolone on CCRF-CEM cells reduced YKL-40. The YKL-40 gene was quantitatively measured using RT-PCR. The Western blot method was used to evaluate changes in the expression of YKL-40 protein. CONCLUSION In this study, we first evaluated YKL-40 expression and resveratrol and prednisolone effect on YKL-40 in ALL. This finding supports the idea of targeting YKL-40 as a new drug treatment of ALL and extends the use of resveratrol in antileukemia research.

Abstract
Chemotherapy is the most common method to treat leukemia as well as other types of human cancers. However, drug resistance has remained as the main challenge against the efficacy of treatments. Furthermore, having various adverse effects, chemotherapy drugs are becoming replaced by natural modalities for cancer therapy. In this regard, herbal components such as resveratrol and prednisolone have been identified to sensitize the leukemic cells to programmed cell death through a set of complex processes. In this study, we have examined DNA methylation on the human multidrug resistance gene 1 (MDR1) as a well-known marker for cellular drug resistance. We evaluated the effect of resveratrol and prednisolone on DNA methylation patterns of MDR1 gene promoter in the CCRF-CEM cell line as a representative for acute lymphoblastic leukemia. The study was aimed to clarify whether the MDR1 gene expression is regulated via DNA promoter methylation as a potential underlying mechanism, following exposure to resveratrol and prednisolone. Our data revealed that despite a strong influence to down-regulate the MDR1 expression, Resveratrol and Prednisolone did not alter the methylation pattern, suggesting other regulatory mechanisms in controlling the MDR1 expression in CCRF-CEM cell line. Unchanged status of DNA methylation of MDR1 gene may suggest that Resveratrol and Prednisolone causes the gene expression changes through a distinct mechanism which requires further studies to be understood. A more detailed understanding of the mechanisms beyond the regulation of the genes involved in cancer formation will help to design novel therapeutic strategies to fight the human cancers.

Abstract
Natural product compounds have recently attracted significant attention from the scientific community for their potent effects against inflammation-driven diseases, including cancer. A significant amount of research, including preclinical, clinical, and epidemiological studies, has indicated that dietary consumption of polyphenols, found at high levels in cereals, pulses, vegetables, and fruits, may prevent the evolution of an array of diseases, including cancer. Cancer development is a carefully orchestrated progression where normal cells acquires mutations in their genetic makeup, which cause the cells to continuously grow, colonize, and metastasize to other organs such as the liver, lungs, colon, and brain. Compounds that modulate these oncogenic processes can be considered as potential anti-cancer agents that may ultimately make it to clinical application. Resveratrol, a natural stilbene and a non-flavonoid polyphenol, is a phytoestrogen that possesses anti-oxidant, anti-inflammatory, cardioprotective, and anti-cancer properties. It has been reported that resveratrol can reverse multidrug resistance in cancer cells, and, when used in combination with clinically used drugs, it can sensitize cancer cells to standard chemotherapeutic agents. Several novel analogs of resveratrol have been developed with improved anti-cancer activity, bioavailability, and pharmacokinetic profile. The current focus of this review is resveratrol’s in vivo and in vitro effects in a variety of cancers, and intracellular molecular targets modulated by this polyphenol. This is also accompanied by a comprehensive update of the various clinical trials that have demonstrated it to be a promising therapeutic and chemopreventive agent.

Abstract
Background The phenolic substance resveratrol (RES) is a plant metabolite known to modulate numerous physiological functions and to exert beneficial effects as a cancer-chemopreventing agent and on neurological, hepatic, and cardiovascular systems. Since the compound affects the lifespan of yeast and flies it might be an anti-aging substance. Mechanistically, RES is involved in down regulating the inflammatory response. The pleiotropic effects of RES in cells of the immune and endothelial system were examined in this study. Results Murine macrophages (RAW264.7 cells), human monocytic/leukemia cells (THP-1), PBLs and HUVECs were incubated with RES and activated with inflammatory stimuli such as LPS or TNF-α. Inflammatory mediators and adhesion molecules were measured by multiplex analysis and gene expression was quantified by RT-PCR. In PBLs, which were activated with LPS, RES blunted the production of TNF-α, CCL2/MCP-1, CCL5/RANTES, CXCL8/IL-8, whereas it increased the production of IL-1β, IL-6, CCL4/MIP-1β and CXCL10/IP-10. Thus, in the blood compartment chemokines attracting mainly monocytes were up-regulated by RES, while those attracting T lymphocytes or neutrophils were diminished. At conditions of endothelial dysfunction (ED), RES reduced the expression of cytokines, chemokines, ICAM and GM-CSF in TNF-α activated HUVECs, whereas eNOS expression was corrected to pre-ED homeostasis. In macrophages nitric oxide, PGE2, cytokines (TNF-α, IL-1β, IL-6) and chemokines (CCL2/MCP-1, CCL4/MIP-1β, CCL5/RANTES, CXCL10/IP-10) were reduced by the phenolic substance. Conclusions RES had cell-specific and context-dependent effects, in particular on the expression of IL-1β, IL-6, CCL4/MIP-1β and CXCL10/IP-10. It enhanced cellular features that mirror increased alertness to disturbed immune homeostasis in the vascular-endothelial compartment (e.g. increased production of IL-1β or IL-6), whereas it blunted inflammatory mediators in macrophages and consequently chronic inflammation. We infer from the present in vitro study, that RES has unique properties in the regulation of inflammatory and immune responses, which are controlled in a complex hierarchical and temporal order.

Abstract
BACKGROUND Chemotherapy is one of the common approaches in treatment of cancers, especially leukemia. However, drug resistance phenomena reduce the likelihood of treatment success. Resveratrol is a herbal compound which through complicated processes makes some selected cells sensitive to treatment and induction of apoptosis. In the present study, the effects of resveratrol on the expression of miR 15a and miR16-1 and apoptosis in the CCRF-CEM cell line were investigated. MATERIALS AND METHODS The CCRF-CEM cell line was cultured under standard conditions and changes in miR 15a and miR 16-1 expression were analyzed by real time-PCR technique, with attention to reveratrol dose and time dependence. Also, apoptosis is evaluated by flow cytometry using annexin V and PI. RESULTS CCRF-CEM cells underwent dose-dependent apoptotic cell death in response to resveratrol. MiR 15a and miR 16-1 expression was up-regulated after 24 and 48 hours resveratrol treatment (p<0.05). CONCLUSIONS The results of our study indicate that resveratrol induces apoptosis in a time and dose- dependent manner in CCRF-CEM cells. Also, increased expression level of miR 16-1 and miR 15a by means of resveratrol in CCRF-CEM cells might have a role in apoptosis induction and predisposition. According to our results resveratrol can be regarded as a dietary supplement to improve efficacy of anti-leukemia therapies.

Abstract
Background Pterostilbene (PTER) is a dimethylated analog of the phenolic phytoalexin, resveratrol, with higher anticancer activity in various tumors. Herein, the molecular mechanisms by which PTER exerts its anticancer effects against acute myeloid leukemia (AML) cells were investigated. Methodology and Principal Findings Results showed that PTER suppressed cell proliferation in various AML cell lines. PTER-induced G0/G1-phase arrest occurred when expressions of cyclin D3 and cyclin-dependent kinase (CDK)2/6 were inhibited. PTER-induced cell apoptosis occurred through activation of caspases-8-9/-3, and a mitochondrial membrane permeabilization (MMP)-dependent pathway. Moreover, treatment of HL-60 cells with PTER induced sustained activation of extracellular signal-regulated kinase (ERK)1/2 and c-Jun N-terminal kinase (JNK)1/2, and inhibition of both MAPKs by their specific inhibitors significantly abolished the PTER-induced activation of caspases-8/-9/-3. Of note, PTER-induced cell growth inhibition was only partially reversed by the caspase-3-specific inhibitor, Z-DEVE-FMK, suggesting that this compound may also act through a caspase-independent pathway. Interestingly, we also found that PTER promoted disruption of lysosomal membrane permeabilization (LMP) and release of activated cathepsin B. Conclusion Taken together, our results suggest that PTER induced HL-60 cell death via MAPKs-mediated mitochondria apoptosis pathway and loss of LMP might be another cause for cell apoptosis induced by PTER.

Abstract
Sirtuin-1 (SIRT1), NAD(+)-dependent deacetylase, has been linked to anabolic effects in cartilage, although the mechanisms of SIRT1 signaling during differentiation of mesenchymal stem cells (MSCs) to chondrocytes are poorly understood. Therefore, we investigated the role of SIRT1-mediated signaling during chondrogenic differentiation of MSCs in vitro. High density and alginate cultures of MSCs were treated with chondrogenic induction medium with/without the SIRT1 inhibitor nicotinamide, antisense oligonucleotides against SIRT1 (SIRT1-ASO), IL-1β, and/or resveratrol. Transient transfection of MSCs with SIRT1-antisense oligonucleotides, nicotinamide, and IL-1β inhibited chondrogenesis-induced down-regulation of cartilage-specific proteins, cartilage-specific transcription factor Sox9, and enhanced NF-κB-regulated gene products involved in the inflammatory and degradative processes in cartilage (MMP-9, COX-2, and caspase-3), and NF-κB phosphorylation, acetylation, and activation of IκBα kinase. In contrast, the SIRT1 activator resveratrol or BMS-345541 (inhibitor of IKK) inhibited IL-1β- and NAM-induced suppression of cartilage-specific proteins, Sox9, and up-regulation of NF-κB-regulated gene products. Moreover, SIRT1 was found to interact directly with NF-κB and resveratrol-suppressed IL-1β and NAM but not SIRT1-ASO-induced NF-κB phosphorylation, acetylation, and activation of IκBα kinase. Knockdown of SIRT1 by mRNA abolished the inhibitory effects of resveratrol on inflammatory and apoptotic signaling and Sox9 expression, suggesting the essential role of this enzyme. Finally, the modulatory effects of resveratrol were found to be mediated at least in part by the association between SIRT1 and Sox9. These results indicate for the first time that SIRT1 supports chondrogenic development of MSCs at least in part through inhibition/deacetylation of NF-κB and activation of Sox9.

Abstract
Nontoxic naturally occurring compounds, especially those from dietary sources, are receiving increasing consideration for prevention and treatment of diseases including cancer. There is a growing need for innovative anticancer therapies and therefore search for natural compounds with novel biological activities or antineoplastic potential is currently an important area in drug discovery. Support for this interest also comes from increasing concern over the efficacy and safety of many conventional therapies, especially those that run over a long course of time. Laboratory studies in different in vitro and in vivo systems have shown that many natural compounds possess the capacity to regulate response to oxidative stress and DNA damage, suppress angiogenesis, inhibit cell proliferation and induce autophagy and apoptosis. This review discusses the induction of apoptosis and autophagy as a mechanism of cancer prevention by some of the most studied naturally occurring dietary compounds.

Abstract
Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen that can cause severe pulmonary infection in immunocompromized individuals. During the infectious process, P. aeruginosa provokes a potent inflammatory response and induces the release of reactive oxygen species (ROS). Cells undergo oxidative stress when cellular antioxidants are unable to effectively scavenge and detoxify ROS, resulting in lung damage. Resveratrol (3,5,4'-trihydroxystilbene) is a natural polyphenolic compound with recognized antioxidant effects. We hypothesized that owing to its antioxidant activities, resveratrol can attenuate an inflammatory response in P. aeruginosa-infected cells. Lung epithelial A549 cells were pre-treated with 100 μmol/L of resveratrol for 5 h, followed by infection with P. aeruginosa. Intracellular ROS generation was used as an indicator of P. aeruginosa-induced oxidative stress, and cell surface expression of Fas receptor and activation of caspases-3 and -7 as indicators of apoptosis. We also measured the surface expression of intercellular adhesion molecule (ICAM)-1 and enzymes related to inflammation and redox signaling. Resveratrol significantly reduced ROS generation, ICAM-1, and human beta-defensin-2 expression, as well as the markers of apoptosis in A549 cells infected with P. aeruginosa, and up-regulated glutathione peroxidase, suggesting its potential therapeutic role in protecting the lungs against the deleterious effects of P. aeruginosa infection.

Abstract
Vitis thunbergii var. taiwaniana (VTT) is an indigenous Taiwanese wild grape and is used as a folk medicine in Taiwan. VTT is rich in polyphenols, especially quercetin and resveratrol derivatives, which were demonstrated to exhibit inhibitory activities against carcinogenesis and prevent some neurodegenerative diseases. (-)-Vitisin B is one of the resveratrol tetramers extracted from VTT. In this study, we investigated the mechanisms of (-)-vitisin B on the induction of apoptosis in human HL-60 promyelocytic leukemia cells. First, (-)-vitisin B significantly inhibited cell proliferation through inducing cell apoptosis. This effect appeared to occur in a time- and dose-dependent manner. Cell-cycle distribution was also examined, and we found that (-)-vitisin B significantly induced a sub-G1 population in a dose-dependent manner. In addition, (-)-vitisin B exhibited stronger inhibitory effects on cell proliferation than resveratrol. Second, (-)-vitisin B dose dependently induced apoptosis-related protein expressions, such as the cleavage form of caspase-3, caspase-8, caspase-9, poly(ADP ribose) polymerase, and the proapoptotic Bax protein. Third, (-)-vitisin B treatment also resulted in increases in c-Jun N-terminal kinase (JNK) phosphorylation and Fas ligand (FasL) expression. Moreover, the (-)-vitisin B-induced FasL expression and caspase-3 activation could be reversed by a JNK inhibitor. These results suggest that (-)-vitisin B-induced apoptosis of leukemia cells might be mediated through activation of JNK and Fas death-signal transduction.

Abstract
Background and hypothesis The high sensitivity of hematopoietic cells, especially stem cells, to radiation and to pro-oxidative and other leukemogenic agents is related to certain of their morphological and metabolic features. It is attributable to the low (minimal) number of active mitochondria and the consequently slow utilization of O2 entering the cell. This results in an increased intracellular partial pressure of O2 (pO2) and increased levels of reactive oxygen (ROS) and nitrogen (RNS) species, and a Δ(PO – AO) imbalance between the pro-oxidative (PO) and antioxidative (AO) constituents. Proposed mechanism Because excessive O2 is toxic, we suggest that hematopoietic cells exist in a kind of unstable dynamic balance. This suggestion is based on the idea that mitochondria not only consume O2 in the process of ATP production but also constitute the main anti-oxygenic stage in the cell's protective antioxidative system. Variations in the mitochondrial base capacity (quantity and quality of mitochondria) constitute an important and highly efficient channel for regulating the oxidative stress level within a cell. The primary target for leukemogenic agents is the few mitochondria within the hematopoietic stem cell. Disturbance and weakening of their respiratory function further enhances the initial pro-oxidative state of the cell. This readily results in peroxygenation stress, creating the necessary condition for inducing leukemogenesis. We propose that this is the main cause of all related genetic and other disorders in the cell. ROS, RNS and peroxides act as signal molecules affecting redox-sensitive transcription factors, enzymes, oncogenes and other effectors. Thereby, they influence the expression and suppression of many genes, as well as the course and direction of proliferation, differentiation, leukemogenesis and apoptosis. Differentiation of leukemic cells is blocked at the precursor stage. While the transformation of non-hematopoietic cells into tumor cells starts during proliferation, hematopoietic cells become leukemic at one of the interim stages in differentiation, and differentiation does not continue beyond that point. Proliferation is switched to differentiation and back according to a trigger principle, again involving ROS and RNS. When the leukemogenic ΔL(PO – AO) imbalance decreases in an under-differentiated leukemia cell to the differentiation level ΔD(PO – AO), the cell may continue to differentiate to the terminal stage. Conclusion The argument described in this article is used to explain the causes of congenital and children's leukemia, and the induction of leukemia by certain agents (vitamin K3, benzene, etc.). Specific research is required to validate the proposals made in this article. This will require accurate and accessible methods for measuring and assessing oxidative stress in different types of cells in general, and in hematopoietic cells in particular, in their different functional states.

Abstract
This study aims to evaluate and compare the antiproliferative and proapoptotic effects of resveratrol (trans-3,4',5-trihydoxystilbene) with two of its naturally occurring oligomers, epsilon-viniferin (a dimer) and miyabenol C (a trimer). Proliferation assays performed on myeloid and lymphoid cell lines show that the three compounds inhibit cell growth of all cell types tested, with miyabenol C being the most efficient (IC50 ranging from 10.8 to 29.4 muM). Further analysis performed on the multiple myeloma cell line U266 shows that all compounds modify cell cycle distribution probably via actions on different targets. Whereas cells treated with resveratrol accumulate in S phase, cells treated with epsilon-viniferin and miyabenol C accumulate in G2/M and G0/G1, respectively. Miyabenol C is also the most efficient at inducing cell death in U266 cells. All compounds induce apoptosis of U266 cells via mechanisms entirely dependent on caspase activation and associated with mitochondrial membrane potential disruption. Compounds do not act directly on the mitochondrial membrane, but could induce activation of upstream caspases such as caspase 8 and/or caspase 2, depending on the compound. In no case did upstream caspase 8 activation involve Fas/FasL interaction. Taken together, these results show that epsilon-viniferin and, more importantly, miyabenol C represent potent antitumor agents that require further investigation, either alone or in combination with resveratrol.

Abstract
Evaluation of Resveratrol and Piceatannol Cytotoxicity in Macrophages, T Cells, and Skin CellsThe cytotoxicity of resveratrol and of piceatannol, a structural analog of resveratrol, was examined in cultured cells. Using a MTT-based assay, which measures the conversion of 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) to a colored formazan product in living cells, resveratrol was found to inhibit the viability of transformed mouse macrophages, tumor-derived human T cells and human epidermoid carcinoma cells in a concentration-dependent manner, with the effect decreasing in the order: T cells (LC50 ~27 μmol L-1, 24 h; ~9 μmol L-1; 48h) > macrophages (LC50~29 μmol L-1, 24 h; 39 μmol L-1, 48 h) > skin cells (LC50 ~91 μmol L-1, 24 h; ~66 μmol L-1, 48 h). Paradoxically, a high concentration of resveratrol (50 μmol L-1) inhibited the proliferation of all three cell types, and a low concentration (5 μmol L-1) stimulated the proliferation of macrophages. The viability of macrophages was also decreased by piceatannol in a concentration-dependent manner. The stimulation of macrophages with zymosan lowered the cytotoxicity of both resveratrol and piceatannol. Scanning electron microscopy of cells treated with resveratrol revealed changes in cellular morphology that were consistent with toxicity. In macrophages and skin cells, resveratrol (50 μmol L-1) induced a time-dependent increase in reduced glutathione levels but did not alter the background levels of thiobarbituric acid-reactive substances. Taken together, the present data indicate that resveratrol is toxic to cultured macrophages, T cells and skin cells at concentrations ≥25 μmol L-1, and that the cytotoxicity occurs via a mechanism that does not involve oxidative stress. Furthermore, the degree of toxicity of both resveratrol and piceatannol towards macrophages depends on the activation status of these cells, with zymosan-activated cells appearing more resistant than nonstimulated cells.

Abstract
Resveratrol is a polyphenolic phytoalexin that is present in various fruits, in the skin of red grapes and peanuts. Recent studies have shown that resveratrol exhibits potent antioxidant properties and is able to exert anti-inflammatory and anti-catabolic properties in several cell types. The pro-inflammatory cytokine interleukin-1beta (IL-1beta) plays a pivotal role in the pathogenesis of osteoarthritis (OA) in humans and animals. In this article we investigated whether resveratrol is able to block the effects of IL-1beta, specifically the activation of caspase-3 and subsequent cleavage of poly (ADP-ribose) polymerase (PARP) in human articular chondrocytes. Cultures of human chondrocytes were prestimulated with 10 ng/mL IL-1beta for 1, 12, and 24 h before being co-treated with IL-1beta and 100 microM resveratrol or 50 microM of the caspase inhibitor Z-DEVD-FMK for 1, 12, and 24 h, respectively in vitro. Resveratrol significantly reduced the IL-1beta-induced inhibition of expression of cartilage-specific collagen type II and signal transduction receptor beta1-integrin in a time-dependent manner. Incubation of chondrocytes with IL-1beta resulted in the activation of caspase-3 and PARP cleavage. These effects were abolished through co-treatment with resveratrol. Furthermore, co-treatment of IL-1beta-stimulated cells with the caspase inhibitor Z-DEVD-FMK blocked activation of caspase-3 and PARP cleavage, suggesting that this process is a caspase-dependent pathway. In summary, our results confirm that resveratrol is an effective inhibitor of chondrocyte apoptosis in vitro. These findings suggest that this dietary polyphenolic compound may have future applications in the nutraceutical-based therapy of human and animal OA.

Abstract
Resveratrol is a naturally occurring polyphenol, which causes apoptosis in cultured cancer cells. We describe a cell surface resveratrol receptor on the extracellular domain of hetero-dimeric alphaVbeta3 integrin in MCF-7 human breast cancer cells. This receptor is linked to induction by resveratrol of extracellular-regulated kinases 1 and 2 (ERK1/2)- and serine-15-p53-dependent phosphorylation leading to apoptosis. The integrin receptor is near the Arg-Gly-Asp (RGD) recognition site on the integrin; an integrin-binding RGD peptide inhibits induction by resveratrol of ERK1/2- and p53-dependent apoptosis. Antibody (Ab) to integrin alphaVbeta3, but not to alphaVbeta5, inhibits activation by resveratrol of ERK1/2 and p53 and consequent apoptosis in estrogen receptor-alpha (ERalpha) positive MCF-7, and ERalpha-negative MDA-MB231 cells. Resveratrol is displaced from the purified integrin by an RGD, but not RGE, peptide, and by alphaVbeta3 integrin-specific Ab. Resveratrol action is blocked by siRNAbeta3, but not by siRNAalphaV. [14C]-Resveratrol binds to commercially purified integrin alphaVbeta3 and to alphaVbeta3 prepared from MCF-7 cells; binding of [14C]-resveratrol to the beta3, but not to the alphaV monomer, is displaced by unlabeled resveratrol. In conclusion, binding of resveratrol to integrin alphaVbeta3, principally to the beta3 monomer, is essential for transduction of the stilbene signal into p53-dependent apoptosis of breast cancer cells.

Abstract
Cancer, one of the major causes of death across the world, has shown to be a largely preventable disease, highly susceptible to modulation by dietary factors. Phenolic compounds, abundant in vegetables and fruits ubiquitous in diet, were described to play an important role as chemopreventive agents. Since conventional therapeutic and surgical approaches have not been able to control the incidence of most cancer types, the development of chemopreventive strategies is an urgent priority in public health. The current diet phenolic intake is often insufficient to protect from mutagens (either exogenous or endogenous), which leads to the need for dietary supplementation as an alternative approach. Research efforts are placing increasing emphasis on identifying the biological mechanisms and in particular the signal transduction pathways related to the chemopreventive activities of these compounds. These effects are believed to occur by the regulation of signaling pathways such as nuclear factor-kappaB (NF-kappaB), activator protein-1 (AP-1) or mitogen-activated protein kinases (MAPK). Dietary polyphenols can exert their effects on these pathways separately or sequentially and in addition the occurrence of crosstalk between these pathways cannot be overlooked. By modulating cell signaling pathways, polyphenols activate cell death signals and induce apoptosis in precancerous or malignant cells resulting in the inhibition of cancer development or progression. However, regulation of cell signaling pathways by dietary polyphenols can also lead to cell proliferation/survival or inflammatory responses due to increased expression of several genes. The present review summarizes the most recent advances providing new insights into the molecular mechanisms underlying the promising anticarcinogenic activity of dietary polyphenols.

Abstract
Many in vitro studies demonstrated significant biological effects of trans-resveratrol. Thus, understanding the rate of intestinal absorption and metabolization in vivo of trans-resveratrol is the prerequisite to evaluate its potential health impact. Bioavailability studies mainly in animals or in humans using the pure compound at very high doses were performed. In this work, trans-resveratrol bioavailability from a moderate consumption of red wine in 25 healthy humans has been studied by three different experiments. The wine ingestion was associated to three different dietary approaches: fasting, a standard meal, a meal with high and low amount of lipids. Trans-resveratrol 3- and 4'-glucuronides were synthesized, purified, and characterized as pure standards. Bioavailability data were obtained by measuring the concentration of free, 3-glucuronide and 4'-glucuronide trans-resveratrol by high-performance liquid chromatography (HPLC), both with ultraviolet (UV) and mass spectrometry (MS) detection, in serum samples taken at different times after red wine administration. Free trans-resveratrol was found, in trace amounts, only in some serum samples collected 30 min after red wine ingestion while after longer times resveratrol glucuronides predominated. Trans-resveratrol bioavailability was shown to be independent from the meal or its lipid content. The finding in human serum of trans-resveratrol glucuronides, rather than the free form of the compound, with a high interindividual variability, raises some doubts about the health effects of dietary resveratrol consumption and suggests that the benefits associated to red wine consumption could be probably due to the whole antioxidant pool present in red wine.

Abstract
Shiga toxins (Stxs) induce apoptosis in a variety of cell types. Here, we show that Stx1 induces apoptosis in the undifferentiated myelogenous leukemia cell line THP-1 in the absence of tumor necrosis factor alpha (TNF-alpha) or death receptor (TNF receptor or Fas) expression. Caspase-8 and -3 inhibitors blocked, and caspase-6 and -9 inhibitors partially blocked, Stx1-induced apoptosis. Stx1 induced the mitochondrial pathway of apoptosis, as activation of caspase-8 triggered the (i) cleavage of Bid, (ii) disruption of mitochondrial membrane potential, and (iii) release of cytochrome c into the cytoplasm. Caspase-8, -9, and -3 cleavage and functional activities began 4 h after toxin exposure and peaked after 8 h of treatment. Caspase-6 may also contribute to Stx1-induced apoptosis by directly acting on caspase-8. It appears that functional Stx1 holotoxins must be transported to the endoplasmic reticulum to initiate apoptotic signaling through the ribotoxic stress response. These data suggest that Stxs may activate monocyte apoptosis via a novel caspase-8-dependent, death receptor-independent mechanism.

Abstract
Rhabdomysarcoma is the most common soft tissue tumour in children under the age of 15. Although the introduction of multimodal treatment programmes, including chemotherapy, radiation therapy and excision have increased the overall survival, the chemotherapeutic agents currently used for the treatment of rhabdomyosarcoma exhibit considerable toxicity. The aim of this study was to investigate the effects and possible mechanism(s) of action of resveratrol on human embryonal rhabdomyosarcoma (RD) cells. Resveratrol is a natural polyphenolic compound produced in a number of edible plants and has received considerable attention as a potential chemopreventive and/or chemotherapeutic agent against various types of cancers. In the present study, resveratrol was shown to inhibit cell proliferation of RD cells in a dose-dependent manner with an IC50 of 48.1 micromol/l and induce an arrest in the S/G2 phase of the cell cycle. As evident from immunocytochemical data, resveratrol treatment increased the size of the RD cells. Furthermore, resveratrol treatment resulted in a significant downregulation of cyclin B expression as demonstrated by western blot analyses. In conclusion, the present study shows that resveratrol exerts a strong inhibition of rhabdomyosarcoma cell proliferation in part by arresting cells in S/G2 phase of the cell cycle. These findings warrant further investigation to establish potential use of resveratrol as a relatively non-toxic chemotherapeutic agent for the treatment of rhabdomyosarcoma.

Abstract
The intracellular bacterium Chlamydia pneumoniae is involved in the inflammation process of atherosclerosis. We previously demonstrated that C. pneumonia infected monocytes (THP-1 cells) responded to stimulation by an increased respiratory burst linked to an increased NADPH oxidase (NOX) activity. We now tested agents acting on the assembly of the NOX subunits or on protein kinase C, a trigger of NOX activity. Apocynin, resveratrol, rutin, quercetin, curcumin, and tocopherols were tested. The cells were pre-incubated with Chlamydia and the agent for 19 h, and then stimulated with phorbol myristate acetate. The NOX activity was monitored by measuring the hydrogen peroxide production. Resveratrol and curcumin (10(-4)-10(-6) M) were better inhibitors than apocynin. alpha-Tocopherol was inactive, and gamma-tocopherol inhibitor at 10(-4) M only. Quercetin was inactive, and rutin a moderate but significant inhibitor. The inhibition by resveratrol was increased by 10(-6) M rutin or quercetin. Resveratrol and curcumin thus appeared to be interesting for atherosclerosis treatment.

Abstract
Resveratrol, a dietary phytoalexin, has emerged as a promising chemopreventive agent due to its antiproliferative and pro-apoptotic action toward cancer cells and its ability to inhibit tumor growth in animals. Gastric adenocarcinoma cells respond to resveratrol treatment with suppression of DNA synthesis, activation of nitric oxide synthase, induction of apoptosis and inhibition of total PKC and PKC alpha activity. Here we demonstrate that treatment of gastric adenocarcinoma SNU-1 cells with resveratrol results in time and concentration dependent accumulation of tumor suppressors p21(cip1/WAF-1) and p53 and is preceded by loss of membrane-associated PKC delta protein and a concomitant increase in cytosolic PKC alpha. Arrest of the cell cycle at transition of S to G(2)/M phases correlates with the profile of (3)H-thymidine incorporation and accumulation of p21(cip1/WAF-1) and was temporally dependent on increase of p53. SNU-1 cells respond to resveratrol treatment with up-regulation of both Fas and Fas-L proteins, whereas in KATO-III cells, with deleted p53, only Fas-L is increased after resveratrol treatment. Although Fas and Fas-L proteins in SNU-1 cells and Fas-L in KATO-III cells were elevated within 24 h of cell treatment with low concentrations of resveratrol, significant apoptotic response at these concentrations was observed only after 48 h. Altogether, our findings indicate that resveratrol engages PKC alpha and delta signals in gastric adenocarcinoma SNU-1 cells prior to up-regulation of antiproliferative and pro-apoptotic signals. The specific cell death signals engaged by resveratrol appear to be cell type dependent and suggest that resveratrol has chemopreventive potential even after mutational changes have occurred.

Abstract
Resveratrol (3,4',5-trihydroxy-trans-stilbene), a phytoalexin found in grape skins, peanuts, and red wine, has been reported to exhibit a wide range of biological and pharmacological properties. It has been speculated that dietary resveratrol could be an explanation for the so-called 'French paradox' as it may act as an antioxidant, promote nitric oxide production, inhibit platelet aggregation, and increase high-density lipoprotein cholesterol, and thereby serve as a cardioprotective agent. Recently, it has been demonstrated that resveratrol can function as a cancer chemopreventive agent, and there has been a great deal of experimental effort directed toward defining this effect. It has been shown that resveratrol and some of its analogs interfere with signal transduction pathways, modulate cell cycle-regulating proteins, and is a potent inducer of apoptosis in multiple carcinoma cell lines. This review summarizes the recent advances that have provided new insights into the molecular mechanisms underlying the promising properties of resveratrol.

Abstract
Pterostilbene and 3,5-hydroxypterostilbene are the natural 3,5-dimethoxy analogs of trans-resveratrol and piceatannol, two compounds which can induce apoptosis in tumor cells. In previous studies we demonstrated the importance of a 3,5-dimethoxy motif in conferring pro-apoptotic activity to stilbene based compounds so we now wanted to evaluate the ability of pterostilbene and 3,5-hydroxypterostilbene in inducing apoptosis in sensitive and resistant leukemia cells. When tested in sensitive cell lines, HL60 and HUT78, 3'-hydroxypterostilbene was 50-97 times more potent than trans-resveratrol in inducing apoptosis, while pterostilbene appeared barely active. However, both compounds, but not trans-resveratrol and piceatannol, were able to induce apoptosis in the two Fas-ligand resistant lymphoma cell lines, HUT78B1 and HUT78B3, and the multi drug-resistant leukemia cell lines HL60-R and K562-ADR (a Bcr-Abl-expressing cell line resistant to imatinib mesylate). Of note, pterostilbene-induced apoptosis was not inhibited by the pancaspase-inhibitor Z-VAD-fmk, suggesting that this compound acts through a caspase-independent pathway. On the contrary, 3'-hydroxypterostilbene seemed to trigger apoptosis through the intrinsic apoptotic pathway: indeed, it caused a marked disruption of the mitochondrial membrane potential delta psi and its apoptotic effects were inhibited by Z-VAD-fmk and the caspase-9-inhibitor Z-LEHD-fmk. Moreover, pterostilbene and 3'-hydroxypterostilbene, when used at concentrations that elicit significant apoptotic effects in tumor cell lines, did not show any cytotoxicity in normal hemopoietic stem cells. In conclusion, our data show that pterostilbene and particularly 3'-hydroxypterostilbene are interesting antitumor natural compounds that may be useful in the treatment of resistant hematological malignancies, including imatinib, non-responsive neoplasms.

Abstract
Resveratrol (R-3), a trihydroxy trans-stilbene from grape, inhibits multistage carcinogenesis in animal models. A resveratrol derivative 3,4,5,4′-tetrahydroxystilbene (R-4) exhibits potent growth inhibitory effect against transformed human cells. Here we report that 3,4,5,4′-tetramethoxystilbene (MR-4), converted from R-4, was more potent against cancer cell lines (WI38VA, IMR-90SV, HeLa, LNCaP, HT-29, and HepG2), but had almost no inhibitory effect on the growth of normal cells (WI38, IMR-90, BJ-T) at the concentrations tested. The IC50 value of MR-4 on the growth inhibition of transformed WI38VA human cells was 0.5 μM, as compared to the value of greater than 50 μM for the normal WI38 cells. Resveratrol, however, did not exhibit such clear differential effect and the IC50 value of R-3 for WI38VA cells was about 50 μM. The growth inhibitory effect of MR-4 correlated with the induction of apoptosis in the transformed cells. When normal WI38 cells and transformed WI38VA cells were compared, MR-4 induced increases of the Bax/Bcl-2 mRNA ratio, p53 and Bax protein level, activation of caspases, and DNA fragmentation in transformed, but not in normal cells. Further analysis revealed that MR-4 caused a rapid appearance of perinuclear aggregation of mitochondria in WI38VA but not in WI38 cells, suggesting that the mitochondria could serve as an early target of MR-4. R-3 also induced apoptosis and mitochondrial clustering but only at a much higher concentration, close to 500 μM. Taken together, the specific activation of the mitochondria-mediated apoptotic pathway could be a major reason for the striking differential growth inhibitory effect of MR-4.

Abstract
AIM: To investigate the apoptosis of implanted primary gastric cancer cells in nude mice induced by resveratrol and the relation between this apoptosis and expression of bcl-2 and bax.
METHODS: A transplanted tumor model was established by injecting human primary gastric cancer cells into subcutaneous tissue of nude mice. Resveratrol (500 mg/kg, 1000 mg/kg and 1500 mg/kg) was directly injected beside tumor body 6 times at an interval of 2 d. Then changes of tumor volume were measured continuously and tumor inhibition rate of each group was calculated. We observed the morphologic alterations by electron microscope, measured the apoptotic rate by TUNEL staining method, detected the expression of apoptosis-regulated genes bcl-2 and bax by immunohistoch-emical staining and PT-PCR.
RESULTS: Resveratrol could significantly inhibit carcinoma growth when it was injected near the carcinoma. An inhibitory effect was observed in all therapeutic groups and the inhibition rate of resveratrol at the dose of 500 mg/kg, 1000 mg/kg and 1500 mg/kg was 10.58%, 29.68% and 39.14%, respectively. Resveratrol induced implanted tumor cells to undergo apoptosis with apoptotic characteristics, including morphological changes of chromatin condensation, chromatin crescent formation, nucleus fragmentation. The inhibition rate of 0.2 mL of normal saline solution, 1 500 mg/kg DMSO, 500 mg/kg resveratrol, 1000 mg/kg resveratrol, and 1500 mg/kg resveratrol was 13.68±0.37%, 13.8±0.43%, 48.7±1.07%, 56.44±1.39% and 67±0.96%, respectively. The positive rate of bcl-2 protein of each group was 29.48±0.51%, 27.56±1.40%, 11.86±0.97%, 5.7±0.84% and 3.92±0.85%, respectively by immunohistochemical staining. The positive rate of bax protein of each group was 19.34±0.35%, 20.88±0.91%, 40.02±1.20%, 45.72±0.88% and 52.3±1.54%, respectively by immunohistochemical staining. The density of bcl-2 mRNA in 0.2 mL normal saline solution, 1500 mg/kg DMSO, 500 mg/kg resveratrol, 1000 mg/kg resveratrol, and 1500 mg/kg resveratrol decreased progressively and the density of bax mRNA in 0.2 mL normal saline solution, 1500 mg/kg DMSO, 500 mg/kg resveratrol, 1000 mg/kg resveratrol, and 1500 mg/kg increased progressively with elongation of time by RT-PCR.
CONCLUSION: Resveratrol is able to induce apoptosis of transplanted tumor cells. This apoptosis may be mediated by down-regulating apoptosis-regulated gene bcl-2 and up-regulating the expression of apoptosis-regulated gene bax.

Abstract
The last couple of decades have seen a tremendous increase in interest in the biological properties of natural products as a means to identify novel small compounds that could have potential in clinical medicine. To that end, flavonoids- and flavonoid-like compounds percolate to the top due to their presence in diet constituents and reported beneficial effects on diverse biological processes and disease conditions. As such, the plant polyphenolic antibiotic resveratrol, found in grapes, nuts and wines, has been the focus of many studies aimed at understanding its full range of health beneficial effects. The interest in this compound stems from the earlier observations describing the therapeutic benefits of roots of the oriental medicinal plant from which resveratrol was first isolated. Being a constituent of grapes and wines, the initial work was focused on linking resveratrol to the beneficial cardiovascular effects of moderate wine intake, however, since its reported cancer chemopreventive activity in a murine model of carcinogenesis, there has been a heightened interest in understanding the anti-cancer activity of resveratrol. As a result, a substantial amount of data strongly suggests that resveratrol could affect the process of carcinogenesis through a variety of different mechanisms in different tumor cell types. However, a couple of recent reports provide evidence to the contrary. This critical review attempts to summarize some of these findings and discuss the clinical potential of this compound or its derivatives in the light of the recent conflicting reports.

Abstract
The plant-produced compound, resveratrol (3,5,4'-trihydroxy-trans-stilbene, 3,4,5-THS), induces apoptosis in various human leukemia cell types in vitro, and thus appears to be a promising anti-leukemia agent. In this study, we observed that treatment of resveratrol-resistant Jurkat cells with the resveratrol analogue, 3,4,5-trihydroxy-trans-stilbene (3,4,5-THS), rapidly induced extensive apoptosis, indicating that the apoptotic activity of the analogue differed from that of the parental compound resveratrol. Indeed, we found that treatment of Jurkat cells with 3,4,5-THS, unlike treatment with resveratrol, induced activation of caspase-8 and apoptosis by a Fas-associated death domain (FADD) protein-dependent mechanism without involving the known death ligands CD95 ligand (CD95L), tumor necrosis factor alpha (TNFalpha) and TNF-related apoptosis-inducing ligand (TRAIL). Therefore, 3,4,5-THS induced activation of a FADD-dependent apoptotic mechanism that was unresponsive to the parental compound resveratrol. Therefore, the ability of 3,4,5-THS, but not resveratrol, to induce apoptosis demonstrates a structure-associated apoptotic activity of the resveratrol analogue.

Abstract
Resveratrol, a polyphenol compound found in grapes and red wines, is a prominent anti-cancer agent. In this study, we demonstrate that resveratrol enhanced TNF-alpha, IL-12 and IL-1beta production from LPS activated phorbol myristate acetate (PMA) differentiated THP-1 human macrophages. Expression of CD86 on macrophages was enhanced by resveratrol alone and with LPS. When macrophages were primed with IFN-gamma, resveratrol suppressed the expression of HLA-ABC, HLA-DR, CD80, CD86 and inhibited production of TNF-alpha, IL-12, IL-6 and IL-1beta induced by LPS. The differential impact of resveratrol on expression of CD14 might be correlated with differential response of macrophages to LPS with or without IFN-gamma priming.

Abstract
Resveratrol, a phytoalexin found in grapes and wine, has been shown to exhibit a wide range of pharmacological properties and is believed to play a role in the chemoprevention of human cancer. Resveratrol has also been shown to induce antiproliferation and apoptosis of several leukemia cell lines. In the present study, we investigated the effect of resveratrol in adult T cell leukemia. Our present observations showed that resveratrol induced growth inhibition in all five human T cell lymphotrophic virus-1-infected cell lines examined, with 50% effective dose of 10.4-85.6 mM. In the resveratrol-treated cells, induction of apoptosis was confirmed by annexin V-based analyses and morphological changes. The most surprising observation was that resveratrol treatment resulted in a gradual decrease in the expression of survivin, an antiapoptotic protein, during cell apoptosis. These findings indicate that resveratrol inhibits the growth of human T cell lymphotrophic virus-1-infected cell lines, at least in part, by inducing apoptosis mediated by downregulation in survivin expression. In view of the accumulating evidence that survivin may be an important determinant of a clinical response in adult T cell leukemia, our present findings have led to the suggestion that resveratrol, a common constituent of the human diet, merits further investigation as a potential therapeutic agent for this incurable disease.

Abstract
Resveratrol has tumor-suppressive activities in some in vitro and in vivo experimental systems but its effect on medulloblastoma cells is still unknown. In this study, resveratrol was used to treat four human medulloblastoma cell lines (Med-3, UW228-1, -2 and -3) and its effects on cell growth, differentiation and death were examined by multiple approaches. Expression of Fas, FasL and caspase-3 in the cells without and with resveratrol treatments was examined by immunocytochemical staining and mRNA in situ hybridization and the influence of anti-Fas antibody (200 ng/ml) in cell growth and survival was determined as well. The results demonstrated that resveratrol could suppress growth, promote differentiation and commit its target cells to apoptosis in time- and dose-related fashions. Fas was constitutively expressed but FasL was undetectable in the four lines in spite of resveratrol treatment. Anti-Fas antibody (200 ng/ml) neither inhibited growth nor induced apoptosis of those cell lines. Up-regulated caspase-3 was found in resveratrol-treated populations and appearance of its cleaved form was closely associated with the apoptotic event. These findings suggest for the first time that resveratrol is an effective anti-medulloblastoma agent that kills medulloblastoma cells through a Fas-independent pathway.

Abstract
Resveratrol, a polyphenol found in grape skin and various other food products, may function as a cancer chemopreventive agent for colon and other malignant tumors and possesses a chemotherapeutic potential through its ability to trigger apoptosis in tumor cells. The present study analyses the molecular mechanisms of resveratrol-induced apoptosis in colon cancer cells, with special attention to the role of the death receptor Fas in this pathway. We show that, in the 10-100 microm range of concentrations, resveratrol activates various caspases and triggers apoptosis in SW480 human colon cancer cells. Caspase activation is associated with accumulation of the pro-apoptotic proteins Bax and Bak that undergo conformational changes and relocalization to the mitochondria. Resveratrol does not modulate the expression of Fas and Fas-ligand (FasL) at the surface of cancer cells, and inhibition of the Fas/FasL interaction does not influence the apoptotic response to the molecule. Resveratrol induces the clustering of Fas and its redistribution in cholesterol and sphingolipid-rich fractions of SW480 cells, together with FADD and procaspase-8. This redistribution is associated with the formation of a death-inducing signaling complex (DISC). Transient transfection of either a dominant-negative mutant of FADD, E8, or MC159 viral proteins that interfere with the DISC function, decreases the apoptotic response of SW480 cells to resveratrol and partially prevents resveratrol-induced Bax and Bak conformational changes. Altogether, these results indicate that the ability of resveratrol to induce the redistribution of Fas receptor in membrane rafts may contribute to the molecule's ability to trigger apoptosis in colon cancer cells.

Abstract
BACKGROUND We examined the effect of resveratrol (RS), a nonflavonoid polyphenolic phytoalexin found in grapes and red wine, and RS coincubated with the oxidant 2-deoxy-D-ribose (dR), on apoptosis and on the oxidative metabolic status of normal human peripheral blood mononuclear cells (PBMNCs) isolated ex vivo from healthy donors. MATERIAL AND METHODS Apoptosis was measured by changes of membrane permeability to propidium iodide (PI), plasma membrane exposure of phosphatidylserine (PS) and intracellular caspase activity. Oxidative status was assessed by recording the intracellular glutathione concentration (GSH), the activities of the enzymes y-glutamyltransferase (y-GT) and glutathione-S-transferase (GST), and intracellular lipid peroxidation (MDA). RESULTS Neither apoptotic nor oxidative parameters were affected by culturing PBMNCs in medium containing RS up to 20 micro M for 5 days, while the frequency of cells with intermediate permeability to PI (17% +/- 5) increased at 50 micro M of RS. Thus resveratrol was slightly toxic, but there was little apoptosis in these cells. Peripheral blood mononuclear cells were also grown first in medium plus RS for 24 h and then for 96 h in medium containing RS plus 10 mM of dR, an oxidant sugar that is apoptogenic for human lymphocytes. The apoptotic changes triggered by dR were counteracted by the phytoalexin in a dose-dependent manner, but RS activity was absent at the lowest concentration (5 micro M) and significantly reduced at the highest concentration used (50 micro M). In PBMNCs coincubated with 20 micro M of RS and 10 mM of dR the antioxidant effect of RS manifested with a significant reduction of caspases-3, -8, y-GT, GST activities and MDA content. CONCLUSIONS Peripheral blood mononuclear cells acquire antioxidant capacity when treated with RS. Grape resveratrol may make a useful dietary supplement for minimizing oxidative injury in immune-perturbed states and human chronic degenerative diseases.

Abstract
Resveratrol, an edible polyphenolic stilbene, has been reported to possess substantial antileukemic activities in different leukemia cell lines. We investigated whether resveratrol is active against fresh acute myeloid leukemia (AML) cells and its mechanism of action. Because interleukin 1beta(IL-1beta) plays a key role in proliferation of AML cells, we first tested the effect of resveratrol on the AML cell lines OCIM2 and OCI/AML3, both of which produce IL-1beta and proliferate in response to it. Resveratrol inhibited proliferation of both cell lines in a dose-dependent fashion (5-75 microM) by arresting the cells at S phase, thus preventing their progression through the cell cycle; IL-1beta partially reversed this inhibitory effect. Resveratrol significantly reduced production of IL-1beta in OCIM2 cells. It also suppressed the IL-1beta-induced activation of transcription factor nuclear factor kappaB (NF-kappaB), which modulates an array of signals controlling cellular survival, proliferation, and cytokine production. Indeed, incubation of OCIM2 cells with resveratrol resulted in apoptotic cell death. Because caspase inhibitors Ac-DEVD-CHO or z-DEVD-FMK partially reversed the antiproliferative effect of resveratrol, we tested its effect on the caspase pathway and found that resveratrol induced the activation of the cysteine protease caspase 3 and subsequent cleavage of the DNA repair enzyme poly (adenosine diphosphate [ADP]-ribose) polymerase. Finally, resveratrol suppressed colony-forming cell proliferation of fresh AML marrow cells from 5 patients with newly diagnosed AML in a dose-dependent fashion. Taken together, our data showing that resveratrol is an effective in vitro inhibitor of AML cells suggest that this compound may have a role in future therapies for AML.

Abstract
Polyphenolic compounds, such as resveratrol, are naturally present at high concentration in grape skin, seeds, and red wine. Resveratrol is present in cis and trans isoforms and the major trans isomer is the biologically active one. Epidemiologic studies have revealed a reduced incidence of cardiovascular risk associated with consumers of red wine; this has been popularized as the French paradox. Resveratrol has been shown to have significant antioxidant properties in a variety of in vitro and in vivo models. It can reduce ischemic damage in heart ischemia reperfusion injury and also in brain ischemia/reperfusion in rodent models. Due to the high rate of oxygen consumption in the brain, and especially low levels of antioxidant defense enzymes, this organ is particularly susceptible of free radical damage. Most of the protective biological actions associated with resveratrol have been associated with its intrinsic radical scavenger properties. We have investigated the possibility of other indirect pathways by which resveratrol can exert its neuroprotective abilities. We have specifically tested whether heme oxygenase neuroprotective enzyme could be stimulated after resveratrol treatment. Using primary neuronal cultures, resveratrol was able to significantly induce heme oxygenase 1, whereas vehicle control showed no effect. No detectable toxicity was quantified. It is well established that after stroke significant levels of intracellular heme levels increase. The source of free heme comes mainly from several heme-containing enzymes. Heme (iron-protoporphyrin IX) is a pro-oxidant and its rapid degradation by heme oxygenase is believed to be protective. Moreover, the generation of heme metabolites can also have their own intrinsic cellular properties. All together, increased heme oxygenase activity by resveratrol is a unique pathway by which this compound can exert its neuroprotective actions.
