Osteocrin and Vascular Complications

Study Overview
=================
Brief Summary
-----------------
In this study, we aimed to describe the role of bone-derived factor (osteocrin) in glucose metabolism, micro and macrovascular complications in diabetic patients. Thus, further investigations of the endocrine system through bone-derived hormones may provide as new perspectives on the prediction, prevention, and treatment of diabetes mellitus.

Detailed Description
-----------------
Diabetes mellitus (DM) remained the most common metabolic disorder worldwide occupying the 8th leading cause of death.[1] Defining new predictive biomarkers in diabetes would provide a window of opportunity for preventive and/or therapeutic interventions to prevent or delay the onset of irreversible long-term micro and or macro vascular complications. Progressive micro vascular vaso-degeneration is the major factor in progression of diabetic complications and contribute greatly to the increased mortality and morbidity. [2] Where Hemodynamic-mediated vascular injury was considered as one mechanism in the pathogenesis of diabetic nephropathy. [3] Bone disorders have been drawing attention as a novel diabetic complication, and diabetes is associated with an increased risk of osteoporotic fracture [4-6]. Bone is considered as an endocrine organ that influences various organs and tissues via the secretion of multiple bone derived hormones [7-8]. These endocrinal functions are, for example, glucose homeostasis [9], appetite control [10], fat deposition [11], skeletal muscle adaptation [12], male fertility [13], and cognition [14]. Therefore, these bone-derived hormones can become useful biomarkers for predicting the incidence of diabetes and the progression of diabetic complications. Osteocrin (OSTN), a bone-derived humoral factor, is a small secreted peptide cloned from bone and muscle complementary DNA (cDNA) libraries [15]. Osteocrin (Ostn) is secreted protein produced by cells of the osteoblast lineage that shows a well conserved homology with members of the natriuretic peptide (NP) family with prohormone-like characteristics [17]. To date, the exact role of Ostn has not been elucidated. In this study, we aimed to describe the role of bone-derived factor (osteocrin) in glucose metabolism, micro and macrovascular complications in diabetic patients. Thus, further investigations of the endocrine system through bone-derived hormones may provide as new perspectives on the prediction, prevention, and treatment of diabetes mellitus.
