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 کاملEstrogen receptors and breast cancer.
Estrogen receptors have been assayed in a series of primary breast cancers from postmenopausal women; 59% of which were estrogen-receptor positive. These patients survived for a significantly longer period of time than those whose tumors were estrogen-receptor negative. The effect of estrogen-receptor status was only seen (and then markedly accentuated) in patients who had lymph-node invasion a...
متن کاملRelationship of cytoplasmic and nuclear estrogen receptors and progesterone receptors in human breast cancer.
The qualitative and quantitative relationships between cytoplasmic estrogen receptors (ERC), total nuclear estrogen receptors (ERN), and cytoplasmic progesterone receptors (PGR) in 74 primary and 23 metastatic human breast cancer tissues were studied. A positive correlation between the age of th patients and the receptor concentration was found only for ERC. Although ERN and PGR were more frequ...
متن کاملThe Interaction Between the Expression of Proliferative Biomarkers and Clinical Characteristics in Breast Cancer
Introduction: Proliferation of cancer cells and the potential of metastasis depend on the activity of different biomarkers such as proliferative ones. Proliferative biomarkers including ki-67, cyclin E1, cyclin D1, p27, and p21 were analyzed through immunohistochemistry (IHC) in previous studies. Methods: The current study aimed at investigating the utilizing role of RT-PCR in studying prolife...
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 ...
