Hmga2 promoter analysis in transgenic mice. | LitMetric

AI Article Synopsis

Article Abstract

HMGA2(2) belongs to the high mobility group A (HMGA) family of architectural transcription factors which participate in a wide variety of nuclear processes ranging from transcription to recombination, playing an important role in chromatin remodelling. HMGA2 is expressed during embryogenesis but not by adult somatic tissues, yet it becomes re-expressed following neoplastic transformation. A role in development is underscored by the finding that the inactivation of the Hmga2 gene is responsible for the murine pygmy phenotype. To elucidate mechanisms that control HMGA2 expression, we have previously cloned the gene and identified functional elements involved in its regulation. In this paper, transgenic mice were generated to define genomic regions involved in Hmga2 developmental and tissue-specific transcriptional regulation. A genomic region from -8.1 to -3.7kb upstream from the initiation site has been found to recapitulate most of the spatial and temporal endogenous Hmga2 gene expression.
