BEN is a member of the TFII-I family of helix-loop-helix transcription factors. Both TFII-I and BEN are involved in gene regulation through interactions with tissue-specific transcription factors and chromatin remodeling complexes. Identification of the downstream target genes of TFII-I proteins is critical in delineating the regulatory effects of these proteins. In this study, we conducted a microarray analysis to determine gene expression alterations following the overexpression of BEN in primary mouse embryonic fibroblasts (MEFs). We found the BEN-dependent modulation in the expression of large groups of genes representing a wide variety of functional categories including genes important in the immune response, cell cycle, transcriptional regulation and cell signaling. A set of genes identified by the microarray analysis was validated by independent real-time PCR analysis. Among upregulated genes were Shrm, Tgfb2, Ube2l6, G1p2, Ccl7 while downregulated genes were Folr1, Tgfbr2, Csrp2, and Dlk1. These results support a versatile function of TFII-I proteins in vertebrate physiology and lead to an increased understanding of the BEN-dependent molecular events.
