Induction by fructose force-feeding of histone H3 and H4 acetylation at their lysine residues around the Slc2a5 gene and its expression in mice

Abstract

It has been reported that fructose force-feeding rapidly induced jejunal Slc2a5 gene expression in rodents. We demonstrate in this study that acetylation at lysine (K) 9 of histone H3 and acetylation at K5 and K16 of histone H4 were more enhanced in the promoter/enhancer to transcribed regions of the Slc2a5 gene in fructose force-fed mice than in glucose force-fed mice. However, fructose force-feeding did not induce acetylation at K14 of histone H3, or at K8 and K12 of histone H4 around the Slc2a5 gene. These results suggest that fructose force-feeding induced selective histone acetylation, particularly of H3 and H4, around the jejunal Slc2a5 gene in mice.
