| Abstract |
To characterize the regulatory pattern by a specific transcription regulatory factor, we used a combination of expression analysis with the mouse cDNA microarray composed of 60,000 cDNA clones and cross-linking/chromatin immunoprecipitation (X-ChIP) followed by comparative PCR. Overexpression of mouse hepatocyte nuclear factor-3alpha (HNF-3alpha) in a mouse hepatoma cell line resulted in accompanied perturbed expression of more than 1500 genes. Search for HNF-3alpha consensus recognition sequences in the upstream regions of their coding sequences, which were mapped on the mouse genome, enabled us to mine 300 genes as the potential HNF-3alpha-regulated genes and classify 135 annotated ones into several functional categories. Further X-ChIP/PCR analysis demonstrated in vivo binding of HNF-3alpha to the 5(')-flanking sequences of 25 members selected out of these genes. Besides known HNF-3alpha-regulated genes such as albumin and alpha-fetoprotein genes, the genes newly identified as the HNF-3alpha-regulated ones include three encoding CDP-diacylglycerol-inositol 3-phosphatidyltransferase, phosphatidylserine decarboxylase, and phospholipase A2, which are located en suite in the lipid metabolic pathway in liver. The potential usefulness of the present approach to extensive characterization of gene expression framework directed by a specific transcription regulatory factor is discussed.
