Although many chemotherapies have been developed for melanomas, successful therapy would be aided by the identification of intrinsic mechanisms that are crucial for melanoma survival. Here, we used resveratrol, a phytoalexin, as an anti-melanoma reagent. Applying resveratrol to various human and murine melanoma cell lines, we show that survivin is essential for melanoma survival in vitro and in...

The use of chemopreventive natural compounds represents a promising strategy in the search for novel therapeutic agents in cancer. Resveratrol (3,4',5-trans-trihydroxystilbilene) is a dietary polyphenol found in fruits, vegetables and medicinal plants that exhibits chemopreventive and antitumor effects. In this study, we searched for modulated proteins with preventive or therapeutic potential i...

We report that resveratrol (3,5,4'-trihydroxy-trans-stilbene), a phytoalexin found in grapes and other plant food, induced a breakdown of the mitochondrial transmembrane potential (∆Ψm) in T-acute lymphoblastic leukemia cells and swelling of isolated rat mitochondria. The breakdown of ∆Ψm was accompanied by the production of reactive oxygen species (ROS), and preceded phosphatidylserine exposur...

Rupase: We wanted to investigate the antitumor effects and effect on angiogenesis of resveratrol in rat RT-2 gliomas. Ejs,enenmental Design: RT-2 glioma cells were treated with resveratrol, and then cytotoxicity was assayed, apoptosis was measured by flow-activated cell sorter flow cytometry, and expression of vascular endothelial growth factor was measured by reverse transcription-PCR Tumor si...

Resveratrol (trans-3,4',5,-trihydroxystilbene), a phytoalexin found in grapes, nuts, fruits, and red wine, is a potent antioxidant with cancer-preventive properties. The mechanism by which resveratrol imparts cancer chemopreventive effects is not clearly defined. Here, we demonstrate that resveratrol, via modulations in cyclin-dependent kinase (cdk) inhibitor-cyclin-cdk machinery, results in a ...

Rhabdomyolysis is one of the main causes of community-acquired acute kidney injury (AKI). Although inflammation is involved in the pathogenesis of rhabdomyolysis-induced AKI (RIAKI), little is known about the mechanism that triggers inflammation during RIAKI. Recent evidence has indicated that sterile inflammation triggered by tissue injury can be mediated through multiprotein complexes called ...

Inflammasomes serve as an intracellular machinery to initiate inflammatory response to various danger signals. The present study tested whether an inflammasome centered on nucleotide oligomerization domain-like receptor protein 3 (NLRP3) triggers endothelial inflammatory response to adipokine visfatin, a major injurious adipokine during obesity. NLRP3 inflammasome components were abundantly exp...

Cardiotoxicity is an aggravating side effect of many clinical antineoplastic agents such as arsenic trioxide (As2O3), which is the first-line treatment for acute promyelocytic leukemia (APL). Clinically, drug combination strategies are widely applied for complex disease management. Here, an optimized, cardiac-friendly therapeutic strategy for APL was investigated using a combination of As2O3 an...

Resveratrol, a safe and multi-targeted agent, has been associated with suppression of survival, proliferation and metastasis of cancer, however, the underlying mechanisms for its anti-cancer activity, particularly on cellular signaling during cancer cell migration still remain poorly understood. We investigated the invasion response of two human colorectal cancer (CRC) cells (HCT116 and SW480) ...

Hypertrophic scar (HS) is a dermal fibroproliferative disorder characterized by excessive deposition of extracellular matrix. Here, to investigate the regulative effects of resveratrol, a natural antioxidant compound, on fibroblasts from human skin HS tissue, a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay was used to evaluate the inhibitory effect of resveratrol on c...
