1: Mol Cell Endocrinol. 2004 Apr 30;219(1-2):1-7. About GATA3, HNF3A, and XBP1, three genes co-expressed with the oestrogen receptor-alpha gene (ESR1) in breast cancer. Lacroix M, Leclercq G. Laboratoire Jean-Claude Heuson de Cancerologie Mammaire, Institut Jules Bordet, Universite Libre de Bruxelles, 127 Boulevard de Waterloo, B-1000 Bruxelles, Belgium. marc.lacroix@ulb.ac.be In breast tumours and breast cancer cell (BCC) lines, microarray analyses have revealed that a series of genes are expressed in close association with the oestrogen receptor-alpha (ER-alpha) gene, ESR1. Three of them, GATA3, HNF3A (also known as FOXA1), and XBP1 encode transcription factors. Here, we present these factors and we discuss their potential involvement in the ER-alpha-mediated actions in BCC. We notably show the relations that exist, or that might exist, between these factors and the oestrogen-inducible trefoil factor TFF1. Copyright 2004 Elsevier Ltd.
