| Research Abstract |
We evaluated taste receptor gene expression in the tongue of healthy subjects in comparison with expression in subjects with hypogeusia or spontaneously abnormal taste. Expression rate was significantly decreased in subjects with hypogeusia, and significantly increased in those with spontaneously abnormal taste. Further, gene expression rate was significantly decreased in zinc-deficient rats, and this decreased rate was improved by administration of zinc. Changes in taste receptor gene expression in rats were morphologically shown by in situ hybridization.The mechanism of expression of taste disorder was considered to involve impaired expression of taste receptor genes.
