BACKGROUND Many studies have shown that colon cancer is an estrogen-dependent carcinoma. This study explored the efficacy of endocrine therapy in colon cancer cells with high metastatic potential (HT29). We investigated the proliferation of HT29 cells after exposure to endocrine therapy (tamoxifen) and 5-FU. METHODS Apoptosis was evaluated using flow cytometry. The expression of matrix metall...

objective: thymoquinone (tq), as the main component of nigella sativa plant, shows anticancer properties. this study was aimed to evaluate the combined effect of tq and tamoxifen (tam) on viability and apoptosis of human breast cancer cell lines. materials and methods: in this experimental study, estrogen positive mcf-7 and estrogen negative mda-mb-231 human breast cancer cell lines were induce...

BACKGROUND Bromelain and N-acetylcysteine are two natural, sulfhydryl-containing compounds with good safety profiles which have been investigated for their benefits and application in health and disease for more than fifty years. As such, the potential values of these agents in cancer therapy have been variably reported in the literature. In the present study, the efficacy of bromelain and N-ac...

The aim of this study was to examine the effect of crude bile on the human HepG2 and CCRF-CEM cell lines. Cells were exposed to different dilutions of bile. Antiproliferative effects were determined by the cytotoxic MTT assay. Cells undergoing apoptosis were identified by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Bile administration resulted in dose-dependent c...

Abstract At present, nuclear condensation and fragmentation have been estimated also using Hoechst probes in fluorescence microscopy flow cytometry. However, none of the methods used for quantitative spectrofluorometric assessment. Therefore, aim present study was to develop a assay detection intact cells. We human hepatoma HepG2 renal HK-2 cells cultured 96-well plates treated with potent apop...

BACKGROUND Epidemiological and experimental carcinogenesis studies provide evidence that components of garlic (Allium sativum) have anticancer activity. Hepatocellular carcinoma is highly malignant and metastatic. Currently, there is no effective chemotherapy for patients with advanced Hepatocellular carcinoma leading to an urgent need to seek for novel therapeutic options. AIM To investigate...

Fermentation of dietary fibre by the gut microflora may enhance levels of SCFA, which are potentially chemoprotective against colon cancer. Functional food containing wheat aleurone may prevent cancer by influencing cell cycle and cell death. We investigated effects of fermented wheat aleurone on growth and apoptosis of HT29 cells. Wheat aleurone, flour and bran were digested and fermented in v...

Wilms tumor (WT) is the most common pediatric malignant primary renal tumor. Carboplatin (CRB), a platinum compound is widely used in the treatment of multiple cancers including ovarian, lung, head and neck, and wilm’s tumor. However lower uptake of CRB in cancer cells and toxicity concerns in healthy cells often limited its clinical outcome. The aim of this study was to investigate the antitum...

A newly synthesized indole-derivative is able to induce cytostatic and cytotoxic effects in the colon cancer cells HT29, effecting apoptosis by activation of an intrinsic pathway. Magnesium is involved in both cell growth and apoptosis even though its role in the latter process is not well defined. The aims of this work were: firstly, to verify if magnesium content is related to the proliferati...
