Resveratrol (RV, 3,4',5-trihydroxystilbene) is naturally produced by a wide variety of plants including grapes and peanuts (Arachis hypogaea). However, the yield of RV from peanut stem and its potential radiosensitizing effects in prostate cancer (PCa) have not been well investigated. In this study, we characterized RV in peanut stem extract (PSE) for the first time and showed that both RV and PSE dose-dependently induced cell death in DOC-2/DAB2 interactive protein (DAB2IP)-deficient PCa cells with the radioresistant phenotype...

It is an acknowledged fact that health benefits are derived from fruit- and vegetables-enriched diets. In particular, polyphenols, compounds bearing one or more hydroxyl groups attached to an aromatic ring, are ascribed for most of such beneficial effects. Among them, resveratrol, a phytoalexin found in numerous plant species, and more notably in grapes, has widely piqued the interest of the scientific community by virtue of its anti-aging, anti-inflammatory and anti-oxidant properties. Moreover, evidence claiming resveratrol ability to hinder processes underlying all the three steps of carcinogenesis (tumor initiation, progression and metastasization) has propelled an incredibly massive number of studies aimed at enquiring its eventual clinical potential in the fight against cancer...

Resveratrol, one of the major polyphenols found in red wine, is suggested to have a role as a chemo-prevention or chemotherapy agent in various human cancer models. Herein, we report that resveratrol has a profound antitumor effect on human hepatocellular carcinoma (HCC) cells by down-regulation of the HGF-c-Met signaling pathway. Resveratrol inhibited anchorage-dependent and -independent growth of HCC cells in a dose-dependent manner. Short-term resveratrol exposure substantially decreased HGF-induced c-Met signaling pathway activation, and long-term exposure to resveratrol markedly inhibited c-Met expression on the cell membrane...

Trans-resveratrol (t-Res) is a natural compound of a family of hydroxystilbenes found in a variety of spermatophyte plants. Because of its effects on lipids and arachidonic acid metabolisms, and its antioxidant activity, t-Res is considered as the major cardioprotective component of red wine, leading to the "French Paradox" health concept. In the past decade, research on the effects of resveratrol on human health has developed considerably in diverse fields such as cancer, neurodegenerative and cardiovascular diseases, and metabolic disorders...

Osteosarcoma is the most common primary bone cancer affecting children and adolescents worldwide. Despite an incidence of three cases per million annually, it accounts for an inordinate amount of morbidity and mortality. While the use of chemotherapy (cisplatin, doxorubicin, and methotrexate) in the last century initially resulted in marginal improvement in survival over surgery alone, survival has not improved further in the past four decades. Patients with metastatic osteosarcoma have an especially poor prognosis, with only 30% overall survival...

The role of CYP1A1 and CYP1B1 enzymes in the biotransformation and biological activity of the methylated resveratrol analogue, 3,4,5,4'-tetramethoxystilbene (DMU-212) is still elusive. Our recently published data have shown that one of the metabolites of DMU-212, 3'-hydroxy-3,4,5,4'-tetramethoxystilbene (DMU-214) exerts more potent cytotoxic effects in A-2780 ovarian cancer cell line, as compared to the parent compound. Hence, this study aims to elucidate whether the biological activity of DMU-212 is related to its biotransformation to DMU-214...

BACKGROUND: Skin fibrosis is a debilitating condition that significantly impacts patient quality of life. Ultraviolet phototherapy is currently used to treat several diseases featuring skin fibrosis. High-fluence light-emitting diode-generated red light (HF-LED-RL) does not cause DNA damage associated with skin cancer, and it is generally regarded as safe, portable, and cost-effective. Early clinical observations suggest that LED-generated light may possess antifibrotic effects, although these findings are largely unexplored...

In this study, we have aimed to prepare folic acid-conjugated dextran stearate (DF) polymeric micelles to target resveratrol in lung cancers. The polymeric micelle was nanosized and exhibited a controlled drug release pattern. The resveratrol (RSV)-loaded dextran stearate (RSV-DF) micelles exhibited an enhanced cellular uptake in A549 cells due to the folic acid-based receptor interactions. We have demonstrated that RSV-DF polymeric micelles retain the cytotoxic and metabolic effects of RSV on A549 cancer cells with potencies similar to that of the free compound...

Resveratrol (trans-3,4',5-trihydroxystilbene), a polyphenolic phytoalexin of grapes and other fruits and plants, is a common constituent of our diet and of dietary supplements. Many health-promoting benefits have been connected with resveratrol in the treatment of cardiovascular diseases, cancer, diabetes, inflammation, neurodegeneration, and diseases connected with aging. To explain the pleiotropic effects of resveratrol, the molecular targets of this compound have to be identified on the cellular level. Resveratrol induces intracellular signal transduction pathways which ultimately lead to changes in the gene expression pattern of the cells...

Resveratrol (Res), a natural phytoalexin found in a variety of plants, has significant antitumor activity. Pyruvate kinase M2 (PKM2) has abnormally high expression in various tumor cells, and it has been implicated in the survival of tumors. However, whether and how Res inhibits PKM2 expression is poorly understood. In the present study, we found that treatment with Res inhibited cell proliferation and induced cell apoptosis. The IC50 values of Res against DLD1, HeLa, and MCF-7 cells were 75 ± 4.54, 50 ± 3...

OBJECTIVE: colorectal cancer (CRC) is one of the most common malignancies, associated with high rates of relapse. A notable challenge in treatment is low response rate to current therapies for advanced CRC. The miR-200c plays an essential role in tumor suppression by inhibiting epithelial-mesenchymal transition (EMT). Resveratrol, a natural compound found in red wine, reveals anti-cancer properties in several types of cancers such as CRC. The aim of current study was to evaluate the effects of resveratrol on proliferation, apoptosis, and invasion of HCT-116 cells and also expression of EMT-related genes in presences or absence of miR-200c...

Inhibition of lysine-specific demethylase 1 (LSD1) has recently emerged as an attractive therapeutic target for treating cancer and other diseases. As a continuity of our ongoing effort to identify novel small-molecule LSD1-inhibitors, we designed and synthesized a series of resveratrol derivatives, which were shown to be potent inhibitors of LSD1. Among them, compounds 4e and 4m displayed the most potent LSD1-inhibitory activities in enzyme assays, with IC50 values of 121 nM and 123 nM, respectively. Biochemistry study and docking analysis indicated that compounds 4e and 4m were reversible LSD1 inhibitors...

Resveratrol, a polyphenol found in grapes, peanuts, and red wine, plays different roles in diseases such as cancer and diabetes. Existing information indicates that resveratrol provides cardioprotection, as evidenced by superior postischemic ventricular recovery, reduced myocardial infarct size, and decreased number of apoptotic cardiomyocytes associated with resveratrol treatment in animal models. Cardiovascular benefits are experienced in humans with routine but not acute consumption of red wine. In this concise review, the paradoxical pro- and antiangiogenic effects of resveratrol are described, and different roles for resveratrol in the formation of new blood vessels are explained through different mechanisms...
