cell kinetic study of tamoxifen treated mcf-7 and mda-mb 468 breast cancer cell lines

Cell Kinetic Study of Tamoxifen Treated MCF-7 and MDA-MB 468 Breast Cancer Cell Lines

Apoptosis could be a major mechanism of antitumor effect of tamoxifen. Therefore this study is designed to characterize the kinetic behavior of tamoxifen-induced apoptosis in the estrogen receptor positive (ER+) and negative (ER-) cell lines, MCF-7 and MDA-MB-468. Frequency of cell death was examined by trypan blue and acridine orange staining. Annexin V-Fluorescein/PI was used in flow cytometr...

Apoptotic potential of two Caryophyllaceae species in MCF-7 and MDA-MB-468 cell lines

Background and objectives: Plants have been used to treat diseases like cancer for many years and today the trend towards their use is increasing. One of the most effective mechanisms of plants against cancer is inducing apoptosis. Apoptosis is a programmed cell death which acts opposite to cell division. It starts in response to some stimuli. Despite the effectiveness of apopt...

Defective repair of 8-hydroxyguanine in mitochondria of MCF-7 and MDA-MB-468 human breast cancer cell lines.

Breast cancer is one of the major causes of mortality among women in the United States. Although the causes of breast cancer remain unclear, it has been speculated that DNA base damage may lead to mutations that subsequently can be carcinogenic. Recently, defective oxidative DNA damage repair has been implicated in breast tumorigenesis. The major oxidative DNA lesion, 8-hydroxyguanine (8-oxoG),...

Apoptosis Induced by 13-S-hydroxyoctadecadienoic acid in the Breast Cancer Cell Lines, MCF-7 and MDA-MB-231

Ethanolic Extract of Propolis from Kerman Area Triggers Apoptosis and Arrests Cell Cycle in Three Human Breast Cancer Cell Lines MDA-MB-231, SKBR and MCF-7

Background: Cancer is one of the major health problems worldwide and natural resources are being explored to develop anticancer drugs with fewer side effects. Iranian propolis contains components including flavonoids and polyphenols and has various medicinal properties. The aim of this study was to investigate the effect of Ethanolic Extract of Sirch Propolis (EESP) on three br...
