Sweet taste molecules of T1R2, T1R3, alpha-gustducin and TRPM5 in ileum were dramatically higher than those in duodenum (P<0.01 for each).
Title: Expression of sweet taste receptor and gut hormone secretion in modelled type 2 diabetes.
Low concentration of endogenous GC is necessary and sufficient for induction of T1R3 expression. Higher concentrations may inhibit such induction. This inhibitory effect may be due, at least in part, to a direct action of GC on taste cells.
Title: Involvement of glucocorticoid in induction of lingual T1R3 in rodents.
T1R3 is expressed mainly in beta-cells and the expression levels are different depending upon the nutritional and metabolic conditions.

results suggest that nutritional status alters saccharin preference and the expression of T1R3 in taste buds; these processes may be involved in the mechanisms underlying the modulation of peripheral sweet taste sensitivity, in which leptin plays a role

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
