Bone is recently recognized as an endocrine organ. Accumulating evidence has shown that osteocalcin, which is specifically expressed in osteoblasts and secreted into the circulation, regulates glucose homeostasis by stimulating insulin expression in pancreas and adiponectin expression in adipocytes, resulting in improving glucose intolerance. On the other hand, insulin and adiponectin stimulate osteocalcin expression in osteoblasts, suggesting that positive feedforward loops exist among bone, pancreas, and adipose tissue. In addition, recent studies have shown that osteocalcin enhances insulin sensitivity and the differentiation in muscle, while secreted factors from muscle, myokines, regulate bone metabolism. These findings suggest that bone metabolism and glucose metabolism are associated with each other through the action of osteocalcin. In this review, I describe the role of osteocalcin in the interaction among bone, pancreas, brain, adipose tissue, and muscle.展开更多

Methods: The clinical data of 180 type 2 diabetes mellitus patients in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, China from February 2017 to January 2018 were retrospectively analyzed, including 90 cases of nonalcoholic fatty liver disease patients (group A) and 90 cases of nonalcoholic fatty liver disease-free patients (group B), meanwhile another 100 healthy subjects were selected as the control group. Then various indexes were compared between groups, including serum osteocalcin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), prothrombin activity (PTA), fasting blood glucose (FBG), glycated hemoglobin (HbA1c), triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), fasting insulin (FINS), fasting C peptide (FCP), HOMA insulin resistance index (HOMA-IR), HOMA β-cell function (HOMA-β). Results: The serum osteocalcin and PTA in group A were significantly lower than those in group B and the control group (P<0.05). ALT, AST, and ALP were significantly higher than those in group B and the control group (P<0.05). The FBG and HbA1c in group A were significantly higher than those in group B and the control group (P<0.05). The TG, TC, LDL, and HDL of group A and group B were significantly higher than those of the control group (P<0.05). The FINS, FCP, and HOMA-IR in group A were significantly higher than those in group B and the control group (P<0.05). HOMA-βwas significantly lower than group B and the control group (P<0.05). Pearson correlation analysis showed that the serum osteocalcin was not correlated with ALT, AST, ALP, PTA, HbA1c, TG, TC, LDL, HDL and FINS (P>0.05), but negatively correlated with FBG and HOMA-IR (P<0.05), and positively correlated with FCP and HOMA-β (P<0.05). With serum osteocalcin as the dependent variable, and ALT, AST, ALP, PTA, FBG, HbA1c, TG, TC, LDL, HDL, FINS, FCP, HOMA-IR and HOMA-β as independent variables, multiple stepwise regression analysis showed that the FBG, HOMA-IR and HOMA-β were independent risk factors for osteocalcin. Conclusions: Patients with type 2 diabetes mellitus complicated with nonalcoholic fatty liver disease have lower serum osteocalcin level, which is susceptible to FBG, HOMA-IR, HOMA-β, and other factors.展开更多
