resveratrol cervix cancer

Red and white wine polyphenols have been reported to provide substantial health benefits. In this study, the cytotoxic activity of red and white wine polyphenolic extracts and of resveratrol was evaluated against different cancer cell lines--human cervix adenocarcinoma HeLa, human breast adenocarcinoma MDA-MB-361, and human breast carcinoma MDA-MB-453--and normal human peripheral blood mononuclear cells (PBMCs). Qualitative and quantitative compositions of wine polyphenolic extracts obtained by fractional vacuum distillation of corresponding wines were determined using spectrophotometric methods and high-performance liquid chromatography with diode array detection and liquid chromatography with electrospray ionization-time of flight mass spectrometry analysis...

BACKGROUND: Subchronic administration of the potent pharmaceutical estrogen diethylstilbestrol (DES) to female Fischer 344 (F344) rats induces growth of large, hemorrhagic pituitaries that progress to tumors. Phytoestrogens (dietary plant estrogens) are hypothesized to be potential tumor inhibitors in tissues prone to estrogen-induced cancers, and have been suggested as "safer" estrogen replacements. However, it is unknown if they might themselves establish or exacerbate the growth of estrogen-responsive cancers, such as in pituitary...

A search for new agents that can sensitise cancer cells to ionising radiation is of continual interest and mainly due to the use of radiation in cancer therapy. Resveratrol, a powerful antioxidant has been shown to inhibit carcinogenesis in animal models. The purpose of this study was to examine whether resveratrol can sensitise cancer cells to X-irradiation. The human cancer cell lines examined were HELA (cervix carcinoma), K-562 (chronic myeloid leukemia) and IM-9 (multiple myeloma). The assays that were performed following X-irradiation (doses from 0 to 8 Gy) and/or incubation in the presence of resveratrol (concentrations ranging from 0 to 200 microM), were the following: trypan blue exclusion test to determine cell viability, cell morphology after May-Grunwald Giemsa staining, DNA profile analysis by flow cytometry to assess cell cycle distribution and the presence of the sub-G1 peak...
