| Research Abstract |
In this research project, we have investigated the function of calcium-sensing receptor (CaSR) as the receptor for luminal dietary peptides in gastrointestinal endocrine cells. Secretions of a gut hormone CCK induced by various dietary peptides were partially inhibited by the presence of CaSR antagonists. CaSR-expressing kidney cells also responded to various dietary peptides. These results suggest that CaSR is one of the receptor for dietary peptides in the gastrointestinal tract.
