Environmental estrogens. Finding out your estrogen receptor status.As estrogen circulates through your bloodstream, it attaches to the estrogen receptors in cancerous cells, causing them to divide and accumulate in your body. Estrogen receptor status in breast cancer is associated with remarkably distinct gene expression patterns.Influence of BRCA1 mutations on nuclear grade and estrogen receptor status of breast carcinoma in Ashkenazi Jewish women. High levels of JDP1 mRNA expression were significantly associated with estrogen receptor-positive status (p0.02).We also assessed the effects of 17-estradiol (10 nM) on JDP1 mRNA expression in MCF-7 breast cancer cells. Knowing the hormone receptor status of a breast cancer is important because this information can guide treatment decisions.ER-positive: Breast cancers that have estrogen receptors are called ER-positive (or ER) cancers. The receptor status of breast cancers has traditionally been identified by immunohistochemistry (IHC), which stains the cells based on the presence of estrogenCYP2C192 Polymorphism is Associated with Increased Survival in Breast Cancer Patients Using Tamoxifen. Pharmacogenomics. To understand the relationship between CD44 gene expression and an established variable associated with aggressive behaviour in human breast cancer, we have studied a panel of 6 breast cell lines and 40 breast tumors selected primarily on the basis of estrogen receptor (ER) status.

Meltzer PS: Estrogen receptor status in breast cancer is associated with remarkably distinct gene expression patterns. A search for regulators of estrogen receptor alpha (ERalpha) expression has yielded a set of microRNAs (miRNAs) for which expression is specifically elevated in ERalpha-negative breast cancer.

International journal of cancer Journal international du cancer. Cancer patterns in the Polynesian population of Hawaii and New Zealand were compared with their European counterparts and with the Polynesian population of Samoa. In general, the cancer patterns of the Polynesians are similar rates are higher for stomach, breast The estrogen receptor (ER) was first identified in the 1960s and with the progesterone receptor (PR) became recognized as a predictive marker for which women with breast cancer would respond to hormone treatment. PMID: 11507038 Owner: NLM Status: MEDLINE. Abstract/OtherAbstract: To investigate the phenotype associated with estrogen receptor alpha (ER) expression inNext Document: Phosphatidylinositol-3-OH Kinase (PI3K)/AKT2, activated in breast cancer, regulates and is induced b Purpose. Estrogen receptor (ER) and progesterone receptor (PR) have been used as indicators of endocrine system status since the mid-1970s in theProgesterone receptor is a significant factor associated with clinical outcomes and effect of adjuvant tamoxifen therapy in breast cancer patients. Estrogen receptors (ER) and progesterone receptors (PR also called PgR) may be found in breast cancer cells.If breast cancer cells have estrogen receptors, the cancer is called ER-positive breast cancer. Differences in breast cancer mortality may reflect racial differences in access and response toWe were surprised to discover that estrogen-receptor status only accounted for a portion of theThis analysis confirmed that, despite the higher incidence of ER tumors (which are associated with a The resulting Nf1 indels induced highly penetrant, aggressive mammary adenocarcinomas that express estrogen receptor and progesterone receptor. We identified distinct Nf1 isoforms that were altered during tumorigenesis. To evaluate NF1 in human breast cancer Signup for the Estrogen-receptor Status of Breast Cancer Linked with Chemotherapy Response Newsletter. Join the Community.Because these subtypes have distinct biologic characteristics, they may respond differently to treatments such as chemotherapy. Gruvberger S, Ringnr M, Chen Y, Panavally S, Saal LH, Borg A, Fern M, Peterson C, Meltzer PS: Estrogen receptor status in breast cancer is associated with remarkably distinct gene expression patterns.
