Characterization of a vitamin D3-resistant human chronic myelogenous leukemia cell line.
A variant of the chronic myelogenous leukemia cell line, RWLeu-4, that is resistant to the antiproliferative effects of vitamin D3 was established. Although RWLeu-4 proliferation is inhibited by 1 nmol/L vitamin D3, the resistant cells (JMRD3) continue to proliferate in the presence of 100 nmol/L vitamin D3. Both cells express similar patterns of differentiation-specific antigens after treatmen...
متن کاملThe Genotoxic and Cytotoxic Effects of Bisphenol-A (BPA) in MCF-7 Cell Line and Amniocytes
Bisphenol-A (BPA) is an industrial xenoestrogen used widely in our living environment. Recently, several studies suggested that BPA has destructive effects on DNA and chromosomes in normal body cells via estrogen receptors (ER). Therefore, BPA could be considered as an important mediator in many diseases such as cancer. However, there are still many controversial issues which need clarification...
متن کاملIsolation and characterization of a tamoxifen-resistant cell line derived from MCF-7 human breast cancer cells.
A tamoxifen-resistant variant (R27) was selected by cloning wild type MCF-7 cells. R27 has the same growth rate as MCF-7 under optimal conditions. But tamoxifen has no effect on the growth rate (growth constant of R27 under control condition, 0.071 +/- 0.007 day-1; tamoxifen-treated cells, 0.073 +/- 0.011 day-1) and minimal effects on thymidine incorporation in R27, whereas tamoxifen has a stro...
متن کاملThe Activity of Sirtuin 1 in MCF-7 Breast Cancer Cell Line: The Effects of Visfatin
Background & Objectives: Breast cancer is the most common cancer and the second leading cause of cancer deaths among women. Obesity, hormones, and growth factors are the risk factors for this kind of cancer. One of the changes observed in patients suffering from breast cancer is the elevated Visfatin or nicotinamide phosphoribosyl transferase (NAMPT) in their tumor tissues and blood. The increa...
متن کاملThe Evaluation of Radio-sensitivity Effect of Hydroxyapatite Nanopartical on MCF-7 and Fibroblast Cell Line
Introduction: Hydroxyapatite nanoparticles inhibit the growth of various cancer cells. The inhibitory effect of these nanoparticles on breast cancer cells of mcf7 has also been reported. However, no studies have been done on the effect of the hydroxyapatite nanoparticles on the radiation sensitivities of the MCF7 cell Line. Our goal in this study is to investigate the effect of...
