Estrogen 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 کاملHigh 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 کاملElusive extranuclear estrogen receptors in breast cancer.
Estrogen receptors at the plasma membrane and cytoplasm have been difficult to detect in breast cancer specimens. New imaging approaches are needed to determine the percentage of cancers expressing extranuclear estrogen receptors and their impact on cancer biology and treatment.
متن کاملEstrogen receptors in human breast cancer.
Specific quantitative techniques have been used to measure the cytoplasmic estradiol-binding protein (EBP) in human mammary carcinoma tissue specimens. Sucrose gradient centrifugation reveals EBP to sediment at 8S and 4S. Variable quantities of non-specific estradiol binding occurs in the 4S region of the sucrose gradient necessitating controls to insure specificity of the estradiol protein int...
متن کاملEstrogen-Related Receptors in Breast Cancer and Prostate Cancer
Estrogen-signaling pathways are implicated in the development of breast cancer and prostate cancer. Various studies have focused on additional signaling pathways, mediated by estrogen-related receptors (ERRs). ERRs are constitutively active receptors that share a high degree of homology with the classical estrogen receptors (ERs). However, they do not bind to estrogen, while ERs do. ERRs are in...
