Tumor Suppressor BRCA1 Is Expressed in Prostate Cancer and Controls Insulin-like Growth Factor I Receptor (IGF-IR) Gene Transcription in an Androgen Receptor–Dependent Manner

Abstract excerpt

PURPOSE: The insulin-like growth factor (IGF) system plays an important role in prostate cancer. The BRCA1 gene encodes a transcription factor with tumor suppressor activity. The involvement of BRCA1 in prostate cancer, however, has not yet been elucidated. The purpose of the present study was to examine the functional correlations between BRCA1 and the IGF system in prostate cancer. EXPERIMENTAL DESIGN: An...
