Homeobox B7 (HOXB7) has been found to be overexpressed in numerous types of human cancer. However, the role of HOXB7 in breast cancer remains to be elucidated. The aim of the present study was to investigate the effects of HOXB7 on the proliferation and invasion of breast cancer cells. Initially, reverse transcription quantitative polymerase chain reaction and western blotting were respectively...

Curcuma longa (tumeric) is listed in several therapeutic regimens used the management of cancer. The present study investigated potential cytotoxic effects ethanol extract (turmeric) leaves on HepG2 (a human hepatocellular carcinoma cell line), and MCF-7 mammary gland adenocarcinoma line) cells. cells were exposed to different concentrations; 2, 0.2, 0.02, 0.002, 0.0002, 0.00002, 0.000002 μg/ml...

The epidermal growth factor receptor (EGFR) (ErbB1) and HER-2/neu (ErbB2) are members of the ErbB family of receptor tyrosine kinases. These receptors are overexpressed in a variety of human tumors and overexpression generally correlates with poor prognosis and decreased survival. Lapatinib, a reversible inhibitor of both EGFR and HER-2/neu, has shown some success in achieving clinical response...

Permanent cell culture lines derived from human breast cancer tissue are important experimental models in the study of human breast cancer cell proliferation. In the present work, pimozide, thioridazine, W-13, and W-12 were shown to inhibit MCF-7 human breast cancer cell growth. The 50% inhibition concentration values determined in two proliferation assays, | 'Hjthymidine incorporation and cell...

backgrounds: evidence is accumulating to support disruption of tissue architecture as a powerful event in tumor formation. for the past four decades, intensive cancer research with the premise of “cancer as a cell based-disease” focused on finding oncogenes or tumor suppressor genes. however, the role of the tissue architecture was neglected. three dimensional (3d) cell cultures which can recap...

Cytotoxic activity of gaillardin, a sesquiterpene lactone isolated from Inula oculus-christi L. (Asteraceae), was assessed in the human breast adenocarcinoma cell line MCF-7, human hepatocellular carcinoma cell line HepG-2, human non-small cell lung carcinoma cell line A-549, and human colon adenocarcinoma cell line HT-29, resulting in IC50 values of 6.37, 6.20, 4.76, and 1.81 microg/mL, respec...

The present study aims at the phytochemical profiling of lyophilized pure fruit juice powder of Citrus limon and demonstrates its efficacy as an antitumor agent against human breast cancer cell line (MCF-7). The cytotoxicity was evaluated using the changes in cell morphology, cell viability, and DNA fragmentation, the percentage of cell viability was determined by MTT assay. Our results showed ...

the two stable isotopes of hydrogen, protium (1h) and deuterium (2h) differ in their physicochemical nature. deuterium-depleted water (ddw) significantly inhibited the growth rate of different tumor cell lines in culture media and xenotransplanted mda-mb-231, mcf-7 human breast adenocarcinomas and pc-3 human prostate tumors in vivo. the apoptosis-triggering effect of ddw was demonstrated both i...

Permanent cell culture lines derived from human breast cancer tissue are important experimental models in the study of human breast cancer cell proliferation. In the present work, pimozide, thioridazine, W-13, and W-12 were shown to inhibit MCF-7 human breast cancer cell growth. The 50% inhibition concentration values determined in two proliferation assays, [3H]thymidine incorporation and cell ...
