Lactoferricin-induced apoptosis in estrogen-nonresponsive MDA-MB-435 breast cancer cells is enhanced by C6 ceramide or tamoxifen

Lactoferricin-induced apoptosis in estrogen-nonresponsive MDA-MB-435 breast cancer cells is enhanced by C6 ceramide or tamoxifen.

Bovine lactoferricin (LfcinB) is a cationic peptide that selectively induces caspase-dependent apoptosis in human leukemia and carcinoma cell lines. Ceramide is a second messenger in apoptosis signaling that has been shown to increase the cytotoxicity of various anti-cancer drugs. In this study, we determined whether manipulation of intracellular ceramide levels enhanced LfcinB-induced apoptosi...

CASPASE DEPENDENT APOPTOSIS INDUCED BY CLADRIBINE IN THE ESTROGEN RECEPTOR NEGATIVE BREAST CANCER CELL LINE, MDA-MB468

The purpose of the present study is to investigate the cytotoxicity/apoptotic effect of 2-chloro-2′-deoxyadenosine, cladribine, (2-CdA) in the human breast cancer cell line, MDA-MB468 (estrogen receptor negative, ER−). MTT [3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H tetrazolium bromide] assay, annexin V-Fluorescein/PI and Hoechst 33258 staining were used to detect cytotoxicity and cell apopto...

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

2’-benzoyloxycinnamaldehyde Regulates Pten Independent of Dj-1 in Mda-mb-435 Breast Cancer Cells

2’-Benzoyloxycinnamaldehyde (BCA) is a promising anticancer candidate against several types of cancers, including breast cancer. DJ-1 has been found to act as an oncogene, protecting cells against oxidative stress. A previous study showed that BCA-inducing antiproliferation was associated with continuous decrease in DJ-1 expression in MDA-MB-435 breast cancer cells. In this study, we found that...

Metastasis suppression by breast cancer metastasis suppressor 1 involves reduction of phosphoinositide signaling in MDA-MB-435 breast carcinoma cells.

Several molecules that suppress metastasis without suppressing tumorigenicity have been identified, but their mechanisms of action have not yet been determined. Many block growth at the secondary site, suggesting involvement in how cells respond to signals from the extracellular milieu. Breast cancer metastasis suppressor 1 (BRMS1)-transfected MDA-MB-435 cells were examined for modifications of...
