Function assay: Calcium dose-response for moltilin stimulation
Motilin Receptors (MLNRs) are Gq/11-protein-coupled receptors that mediate progastrokinetic effects. MLNRs are found at their highest concentrations in the nerves of the antral wall of the stomach and are also found at significant levels throughout the smooth muscle of the upper gastrointestinal (GI) tract and in the enteric nervous system. Motilin receptor promotes gastric emptying after food intake and increases smooth muscle contraction in the GI tract, and thus, is clinically a potential drug target for the treatment of hypomotility disorders.
Figure 1. Calcium dose-response for moltilin stimulation of CHO/MLNR cells (MCB) compared to untransfected CHO-K1 cells. The passage 1, passage 7 and passage 13 of CHO/MLNR MCB cells that stably express the MLNR (blue, red and green circle) or untransfected CHO-K1 cells which is the same passage as CHO/MLNR MCB (black circle) were loaded with Fluo-4 NW (Invitrogen), then stimulated with the indicated concentration of moltilin. The change in intracellular calcium was measured by a FlexStation III fluorescent plate reader. Data poins represent the average+/- standard deviation of triplicate determinations.
