Lauryl gallate is an antioxidant food additive showing low toxicity to normal cells. Here, its antiproliferative effect has been studied on three human breast cancer cell lines: estrogen-dependent, wild-type p53, MCF7; estrogen-independent, non-functional p53, MDA-MB-231 and MCF7 ADR, which
OBJECTIVE
Epidermal growth factor receptor (EGFR/ErbB1) is a transmembrane protein with tyrosine kinase activity activated mainly by ligand, EGF. Matrix metalloproteinases (MMPs) are a family of proteinases that catalyses the destruction of ECM, among which MMP-9 has important role in tumor cell
We have previously shown that tamoxifen+epigallocatechin gallate (EGCG) is synergistically cytotoxic towards oestrogen receptor (ER)-negative breast cancer cells. To determine if this response would correlate with significant tumour suppression in vivo, athymic nude female mice were implanted with
Epigallocatechin-3-gallate (EGCG) is effective against the initiation, progression, and invasion of carcinogenesis.Matrix-metalloproteinases (MMPs) are a family of endopeptidases that hydrolyze the majority of extracellular proteins. MMP-9 is one of the most important members of the family and we
This study is to investigate the effect of ethyl gallate on invasion capabilities and its mechanism of breast cancer MDA-MB-231 cells. Using cell adhesion and transwell assay, separately, the effects of ethyl gallate on the invasion of MDA-MB-231 cells were measured. The Akt-NF-κB signal pathway
In this study we characterized (3)H-2-deoxy-d-glucose ((3)H -DG) uptake by the estrogen receptor (ER)-positive MCF7 and the ER-negative MDA-MB-231 human breast cancer cell lines and investigated the effect of quercetin (QUE) and epigallocatechin gallate (EGCG) upon (3)H-DG uptake, glucose metabolism
There are few effective treatment options for radiation-induced dermatitis in breast cancer patients. We conducted a single-arm trial to tested the hypothesis that topical epigallocatechin-3-gallate (EGCG) is effective against radiation-induced dermatitis in breast cancer patients undergoing
In the present work, we investigated the effect of epigallocatechin gallate (EGCG) on triple negative breast cancer cells (Hs578T) to reduce cell proliferation and to evaluate early apoptotic signals. The dynamic monitoring of Hs578T cells treated with EGCG using the xCELLigence System confirm the
(-)-Epigallocatechin-3-gallate (EGCG) is a polyphenolic compound from green tea that has been shown to have anti-tumor activities such as inhibiting adhesion, migration, and proliferation of tumor cells. However, the delicate mechanisms and signaling pathways underlying the potential anticancer
Since the 1980s, the incidence of late-onset breast cancer has been increasing in the United States. Known risk factors, such as genetic modifications, have been estimated to account for approximately 5 to 10% of breast cancer cases, and these tend to be early onset. Thus, exposure to and
METHODS
The aim of this research was to explore whether the tea-polyphenol (-)-epigallocatechin-3-gallate (EGCG) could be used as a potential agent for blocking smoking (nicotine, Nic)- or hormone (estradiol, E2)-induced breast cancer cell proliferation through inhibition of a common signaling
Euphorbia fischeriana Steud is a traditional Chinese Medicine that is known to possess a variety of anticarcinogenic properties. However, the bioactive constituents in Euphorbia fischeriana Steud and molecular mechanisms underlying this action in cancer treatment remain poorly understood. The
High concentrations of specific catechins [epigallocatechin gallate (EGCG), epigallocatechin (EGC) and epicatechin gallate (ECG)] inhibit the proliferation of many different cancer cell lines. The aim of this work was to determine if low concentrations of catechins with and without
Recent investigations have demonstrated that polyphenolic catechins inhibit cancer cell proliferation and tumor growth. However, how the major active component of tea catechins, epigallocatechin-3 gallate (EGCG), mediates anticancerous effects has not been extensively examined. We have investigated
Overexpression of the epidermal growth factor receptor family member Her-2/neu in breast cancer is associated with poor prognosis. With evidence accumulating for a chemopreventive role of green tea polyphenols, the effects of epigallocatechin-3 gallate (EGCG) on Her-2/neu-overexpressing breast
