It has been previously demonstrated that the expression of lactase-phlorizin hydrolase (LPH) and sucrase-isomaltase (SI) genes are higher in rats fed a high-carbohydrate/low-fat (HCT) diet than in those fed a low-carbohydrate/high-fat (LCT) diet. In the present study, using a nuclear run-on assay we clearly show that higher expression of LPH and SI genes in jejunum of rats fed the HCT diet compared with those fed a LCT diet was regulated at the transcription levels. DNase I foot printing analysis of the 5' flanking region of the rat LPH gene demonstrated that by incubating the jejunal nuclear extract the protected region was conserved as the same sequence as the homeodomain protein-binding element designated as CE-LPH1. UV-cross linking and electromobility shift assay in vitro clearly showed that Cdx-2 was including proteins bound to CE-LPH1. Moreover, in vitro binding of Cdx-2 to CE-LPH1 as well as SIF1, a cis-element identified as the binding element of Cdx-2 on the SI gene, in jejunal nuclear extracts of rats fed a HCT diet were greater than those fed a LCT diet. These results suggest that in vitro binding of Cdx-2 to CE-LPH1 as well as SIF1 in jejunal nuclear extracts is associated with the higher expression of the LPH and SI genes in rats fed the HCT diet compared with those fed a LCT diet.

Higher expression of jejunal LPH gene in rats fed the high-carbohydrate/low-fat diet compared with those fed the low-carbohydrate/high-fat diet is associated with in vitro binding of Cdx-2 in nuclear proteins to its promoter regions.
