Krüppel-like factor (KLF)-10, is a circadian transcriptional regulator, which links the molecular clock to energy metabolism in the liver. Recently, it was reported that Klf-10 expression is induced by glucose stimulation in mouse hepatocytes. We previously reported that carbohydrate response element-binding protein (ChREBP) plays an important role in the regulation of hepatic lipogenic gene expression. Here, we investigate whether ChREBP, a glucose-activated transcription factor, directly regulates Klf-10 mRNA expression in rat primary hepatocytes. We found that both glucose stimulation and adenoviral overexpression of ChREBP induce Klf-10 mRNA expression in rat primary hepatocytes in a dose-dependent manner. Conversely, overexpression of dominant-negative Max-like protein inhibits glucose-induction expression of Klf-10 mRNA. Deletion analysis using rat Klf-10 promoter in the pGL3 vector combined with a chromatin immunoprecipitation assay against the anti-ChREBP antibody demonstrated that the carbohydrate response element is located between −125bp and −109bp in the rat Klf-10 promoter. Conversely, adenoviral overexpression of KLF-10 partly inhibits glucose induction of ChREBP target genes in primary hepatocytes. In conclusion, these data suggest that crosstalk between ChREBP and KLF-10 is involved in the regulation of the lipogenic pathway.
