Tissue specific regulation of gene expression by a single transcription factor or group of transcription factors cannot be explained simply by DNA sequence alone. For example, in the same animal a particular transcription factor is capable of interacting with DNA in the nucleus of many different cell types, resulting in unique gene expressions despite the presence of a similar genome in all cells. Historically, these differences in response to a single type of factor within target tissues in the same animal have been suggested to occur through different alterations in chromatin structure. Recent, data has demonstrated that combination of hormones and transcription factors working together may cooperatively play a role in the regulation of gene expression [Pearce and Yamamoto (1993): Science 259:1161–1165]. However, the molecular mechanisms of this tissue specific regulation of gene expression still remains largely unexplained. Current evidence suggests that in different cell types the interplay between the specific three‐dimensional organization of the genome and the structural components of the nucleus, the nuclear matrix, may accomplish the regulation of specific gene expression. © 1994 Wiley‐Liss, Inc.
