Targeting androgen receptor in estrogen receptor-negative breast cancer.
Endocrine therapies for breast cancer that target the estrogen receptor (ER) are ineffective in the 25%-30% of cases that are ER negative (ER-). Androgen receptor (AR) is expressed in 60%-70% of breast tumors, independent of ER status. How androgens and AR regulate breast cancer growth remains largely unknown. We find that AR is enriched in ER- breast tumors that overexpress HER2. Through analy...
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 کاملExpression of Androgen Receptor in Estrogen Receptor–positive Breast Cancer
OBJECTIVES The aim of the study was to estimate the implications of androgen receptor (AR) expression in estrogen receptor (ER)-positive subset of invasive breast carcinoma patients. PATIENTS AND METHODS We assessed the AR expression in a subset of 96 predominantly ER-positive invasive breast carcinomas and correlated this expression pattern with several clinical and pathologic parameters: hi...
متن کاملBreast cancer: from estrogen to androgen receptor.
To investigate the link existing between androgens and human breast cancer, the hormonal milieu present in pre- and post-menopausal women has been translated in an in vitro model utilizing a hormone dependent breast cancer cell line MCF-7 exposed to DHEA, DHEAS, androstenediol, T, DHT with or w/o E(2). DHEAS and androstenediol stimulate the growth of MCF-7 cell line but reduce cell proliferatio...
متن کاملA feedback loop between androgen receptor and ERK signaling in estrogen receptor-negative breast cancer.
Estrogen receptor (ER)-negative breast cancer is heterogeneous, and the biology of this disease has remained poorly understood. Molecular apocrine is a subtype of ER-negative breast cancer that is characterized by the overexpression of steroid-response genes such as AR and a high rate of ErbB2 amplification. In this study, we have identified a positive feedback loop between the AR and extracell...
