Abstract

Hepatocyte Nuclear Factor-1 alpha (HNF-1 alpha) and HNF-1 beta are homeodomain-containing transcription factors which interact with the GTTAATNATTAAC motif essential to the function of more than 15 promoters selectively expressed in the liver. These homeoproteins can form homo- and heterodimers in solution and share identical DNA-binding domains but have different transcriptional activation properties. During retinoic acid (RA) induced differentiation of F9 embryonal carcinoma (EC) cells, which stimulates aspects of pre-implantation embryogenesis, both HNF-1 beta mRNA and immunoreactive DNA-binding activity are strongly induced approximately 24 h post RA-treatment. In contrast, HNF-1 alpha mRNA increases approximately 4-fold after 5 days, concomitant with elevation of HNF-1 alpha DNA-binding activity and expression of the HNF-1 target gene alpha-fetoprotein. These results indicate that HNF-1 alpha and -1 beta expression can be controlled by regulatory hierarchies downstream of primary RA-response genes, and suggest that independent regulatory mechanisms for these factors can confer distinct and interactive developmental functions.
