resveratrol/breast neoplasms

Breast cancer is the most common cause of cancer mortality among women worldwide; therefore, a strategy to defeat breast cancer is an extremely important medical issue. One of the major challenges in this regard is multidrug resistance (MDR). Resveratrol, a well-known phytoestrogen, may be helpful

A synthetic analogue of resveratrol, 4-(6-hydroxy-2-naphtyl)-1,3-benzenediol (HS-1793), with improved photosensitivity and stability profiles, has been recently reported to exert anticancer activity on various cancer cells. However, the molecular mechanism of action and in vivo efficacy of HS-1793

Hormones and their receptors play an important role in the development and progression of breast cancer. Hormones regulate the proliferation of breast cancer cells through binding between estrogen or progestins and steroid receptors that may reside in the cytoplasm or be transcriptionally activated

In breast cancer cells, overexpression of human epidermal growth factor receptor 2 (HER2) increases the translation of fatty acid synthase (FASN) by altering the activity of PI3K/Akt signaling pathways. Cancer chemotherapy causes major side effects and is not effective enough in slowing down the

Resveratrol is a polyphenolic compound present in grapes and wine with anticancer activities that undergoes pronounced metabolism in humans. In order to determine whether metabolism of resveratrol also occurs in tumor cells and whether biotransformation has any impact on cytotoxicity, metabolism

Hippo/YAP signaling is implicated in tumorigenesis and progression of various cancers. By inhibiting a plethora signaling cascades, resveratrol has strong anti-tumorigenic and anti-metastatic activity. In the present study, we demonstrate that resveratrol decreases the expression of YAP target

Natural compounds have been studied as a source of countless bioactive compounds with diverse activities. Among them, many dietary phytochemicals have been thoroughly studied for their cytotoxic or apoptotic effects in several cellular models in order to explain their anticancer capacity. Curcumin

Estrogen plays a crucial role in the development of breast cancer, and the inhibition of estrogen synthesis has been an important target for the prevention and treatment of this disease. The rate-limiting reaction of the hormone biosynthesis is catalyzed by cytochrome P450 (CYP) 19 enzyme or

Resveratrol decreases basal and induced CYP1A1 mRNA/protein levels in both in vitro and in vivo models, and some studies suggest that resveratrol acts as an aryl hydrocarbon receptor (AhR) antagonist. Treatment of T47D or MCF-7 cells with 10 microM resveratrol inhibited induction of CYP1A1 mRNA and

Estrogen and structurally related molecules play critical roles in breast cancer. We reported that resveratrol (50 microM), an estrogen-like phytosterol from grapes, acts in an antiestrogenic manner in breast cancer cells to reduce cell migration and to induce a global and sustained extension of

Alpha-tocopherol ether-linked acetic acid analog [2,5,7,8-tetramethyl-2R-(4R, 8R-12-trimethyltridecyl) chroman-6-yloxyacetic acid (alpha-TEA)] is a novel form of vitamin E effective at killing cancer cells but not normal cells. alpha -TEA alone and together with methylseleninic acid (MSA) and

The role of resveratrol (RES) in preventing breast cancer is controversial, as low concentrations may stimulate the proliferation of estrogen-receptor alpha positive (ERα+) breast cancer cells. As metabolism is the key factor in altering cellular estrogens, thereby influencing breast tumor growth,

OBJECTIVE Drug resistance remains a major challenge for effective breast cancer chemotherapy. Resveratrol (Res) is a promising candidate for overcoming cancer chemoresistance, but it has low bioavailability due to poor absorption, and ready metabolism limits its application. This study aims to

Resveratrol, a natural phytoalexin, has gained much interest on the basis of its potential chemopreventive activity against human cancer. In this work, using the human breast cancer cell lines MCF-7 and MDA-MB-231, we have analyzed a possible mechanism by which resveratrol could interfere with cell

The aim of this study was to assess the efficacy of resveratrol (Res) on radiosensitivity of 5-fluorouracil (5-FU) in the spheroid culture of MCF-7 breast cancer cell line using colony formation examination. Spheroids on day 9 with 300 µm diameters were treated with 20 µM resveratrol and/or 1 µM
