High Expression of Sphingosine Kinase 1 in Estrogen and Progesterone Receptors-Negative Breast Cancer
Background & objective: Breast cancer is the leading cause of cancer related death in females. Sphingosine kinase 1 (SPHK1) and its product sphingosine-1-phosphate (S1P) are the essential key regulator molecules in breast cancer through their ability to promote cell proliferation, angiogenesis, cell proliferation, and lymphagiogenesis. SPHK1 i...
متن کاملADENOSINE DEAMINASE ACTIVITY IN ESTROGEN RECEPTOR POSITIVE AND NEGATIVE HUMAN BREAST CANCER CELL LINES
ABSTRACT Background: The aims of this study were to assay the activity of adenosine deaminase (ADA) in estrogen receptor positive (MCF-7) and negative (MDA-MB468) breast cancer cell lines. Methods: MDA-MB468 and MCF-7 breast cancer cell lines were cultured in complete medium, striped serum with and without 0.0 1~-LM diethylstilbestrol (DES), complete medium in the presence and absence of 111M ...
متن کاملEstrogen Receptor Gene Expression Receptor-negative Breast Cancer Cells Can Reactivate Demethylation of the Estrogen Receptor Gene in Estrogen
Approximately one third of breast cancers grow independently of estrogen, lack detectable estrogen receptor (ER) protein, and rarely re spond to hormonal treatment. Previous studies correlated the lack of ER gene expression in ER-negative breast tumor cells with hypermethylation of a CpG island in the 5' region of the ER gene. In order to determine whether demethylation of the ER gene in the ER...
متن کاملProgressive APOBEC3B mRNA expression in distant breast cancer metastases
BACKGROUND APOBEC3B was recently identified as a gain-of-function enzymatic source of mutagenesis, which may offer novel therapeutic options with molecules that specifically target this enzyme. In primary breast cancer, APOBEC3B mRNA is deregulated in a substantial proportion of cases and its expression is associated with poor prognosis. However, its expression in breast cancer metastases, whic...
متن کاملDemethylation of the estrogen receptor gene in estrogen receptor-negative breast cancer cells can reactivate estrogen receptor gene expression.
Approximately one third of breast cancers grow independently of estrogen, lack detectable estrogen receptor (ER) protein, and rarely respond to hormonal treatment. Previous studies correlated the lack of ER gene expression in ER-negative breast tumor cells with hypermethylation of a CpG island in the 5' region of the ER gene.
