BIOTECHNOLOGY
BACKGROUND
HNF-1 (偽 and
尾),
HNF-3 (偽,
尾
and
緯),
HNF-4 (偽 and
緯),
and
HNF-6 compose, in part, a homoeprotein family designated the
Hepatocyte Nuclear Factor family (1-4). The various HNF-1
isoforms regulate transcription of genes in the liver as well as in
other tissues such as kidney, small intestine and thymus (1).
HNF-3偽, HNF-3尾 and HNF-3緯 regulate the transcription of
numerous hepatocyte genes in adult liver. HNF-3偽 and HNF-3尾
have also been shown to be involved in gastrulation events such as
body axis formation (2,4). HNF-4偽 and HNF-4緯 have been
shown to be important for early embryo development. HNF-4a is
expressed in liver, kidney, pancreas, small intestine, testis and
colon; and HNF-4緯 is expressed in each of these tissues except
liver (3). HNF-6 has been shown to bind to the promoter of
HNF-3尾, which indicates a potential role of HNF-6 in gut
endoderm epithelial cell differentiation. Evidence suggests that
HNF-6 may also be a transriptional activator for at least 22 other
hepatocyte-enriched genes, including cytochrome P450 2C13 and
偽-1
antitrypsin (4).
