Functional Targets of the Monogenic Diabetes Transcription Factors HNF-1α and HNF-4α Are Highly Conserved Between Mice and Humans
OBJECTIVE The evolutionary conservation of transcriptional mechanisms has been widely exploited to understand human biology and disease. Recent findings, however, unexpectedly showed that the transcriptional regulators hepatocyte nuclear factor (HNF)-1alpha and -4alpha rarely bind to the same genes in mice and humans, leading to the proposal that tissue-specific transcriptional regulation has u...
متن کاملRegulation of α1-antitrypsin gene expression in human intestinal epithelial cell line Caco-2 by HNF-1α and HNF-4.
There is still relatively limited information about mechanisms of gene expression in enterocytes and mechanisms by which gene expression is regulated during enterocyte differentiation. Using the human intestinal epithelial cell line Caco-2, which spontaneously differentiates from a cryptlike to a villouslike enterocyte, we have previously shown that there is a marked increase in transcription o...
متن کاملAnalysis of the rat hepatocyte nuclear factor (HNF) 1 gene promoter: synergistic activation by HNF4 and HNF1 proteins.
Hepatocyte nuclear factor (HNF) 1 is a key transcription factor involved in the expression of many liver-specific genes. We have isolated and characterized the promoter region of the rat HNF1 gene. Transfection experiments revealed that a short region between -118 and -8 is crucial for cell type-specific expression of the HNF1 gene in the hepatoma cell line, HepG2 cells. This region contains tw...

متن کامل
The different tissue transcription patterns of genes for HNF-1, C/EBP, HNF-3, and HNF-4, protein factors that govern liver-specific transcription.
The transcription factors that act in hepatocyte-specific gene expression include proteins that are present mainly in liver cells (HNF-1/LFB1, C/EBP, HNF-3, HNF-4) (HNF, hepatocyte nuclear factor; C/EBP, rat enhancer binding protein) and proteins that are widely distributed (AP-1, NF-1, NF-Y/ACF). We show here that the genes encoding each of these liver-enriched factors exhibit different patter...
