Gastrointestinal hormones including gastric inhibitory polypeptide (GIP) and glucagon-like peptide (GLP) -1 are incretin, which are secreted immediately after meal ingestion and stimulate insulin secretion from pancreatic beta-cells. Characterization of extra-pancreatic GIP and GLP-1 receptors has revealed that these hormones regulate bone turnover. GIP intermittently stimulates osteoblasts and GLP-1 suppresses osteoclasts through a calcitonin-dependent pathway to increase the bone volume.
包括胃抑制多肽(GIP)和胰高血糖素样肽(GLP)-1在内的胃肠激素是肠促胰岛素,它们在进食后立即分泌,并刺激胰腺β细胞分泌胰岛素。胰腺外GIP和GLP-1受体的特性表明,这些激素调节骨转换。GIP间歇性刺激成骨细胞,而GLP-1通过降钙素依赖途径抑制破骨细胞,从而增加骨量。
