LEF1 in androgen-independent prostate cancer: regulation of androgen receptor expression, prostate cancer growth, and invasion.
A major obstacle in treating prostate cancer is the development of androgen-independent disease. In this study, we examined LEF1 expression in androgen-independent cancer as well as its regulation of androgen receptor (AR) expression, prostate cancer growth, and invasion in androgen-independent prostate cancer cells. Affymetrix microarray analysis of LNCaP and LNCaP-AI (androgen-independent var...
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 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 کاملDifferential posttranscriptional regulation of androgen receptor gene expression by androgen in prostate and breast cancer cells.
Androgens, via the androgen receptor (AR), modulate the growth and proliferation of prostate and breast cancer cells. However, the molecular mechanisms underlying the regulation of AR gene expression by androgen in these cells remain to be fully elucidated. To explore differences in AR gene expression between these hormone-responsive tumor cell types, we studied androgen-responsive LNCaP prosta...
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...
