| Research Abstract |
DNA microarray analyses were performed to examine a possibility whether difference in the habitual-chewing-load would affect expression of genes that linked to the glucose and lipid metabolism using mice.In a comparison between groups of pellet feeding and powdery feeding, of which components were the same, parotid gland from the obese diabetes mice showed significant difference in the mRNA level in 35% of 194 genes installed to the chip, and ones from the normal mice about 60%. Each genes which showed a significantly different transcription level between the feeding groups, signals of pellet feeding group were higher than ones of powder feeding group.
