Osteoarthritis (OA), one of the most common age-related chronic disorders of articular cartilage, joints, and bone tissue, represents a major public health problem. Genetic studies have identified multiple gene variations associated with an increased risk of OA. These findings suggest that there is a large genetic component to OA and that the disorder belongs in the multigenetic, multifactorial class of genetic diseases. Studies of chondrodysplasias and associated hereditary OA have provided a better understanding of the role of structural genes in the maintenance and repair of articular cartilage, in the regulation of chondrocyte proliferation and gene expression, and in the pathogenesis of OA.
Glucose is an important metabolite and a structural precursor for articular cartilage and its transport has significant consequences for cartilage development and functional integrity. In this study the expression of facilitative glucose transporters (GLUTs) in human chondrocytes was investigated. Results showed that at least three GLUT isoforms (GLUT1, GLUT3 and GLUT9) are expressed by normal chondrocytes. Given the central role of glucose in chondrocyte physiology and metabolism, its regular provision via GLUTs will influence the metabolic activity and survival of chondrocytes in cartilage matrices.
We describe a technique to assist in the stabilization of the costochondral junction using a small strut of synthetic mesh in patients undergoing a thoracoabdominal incision.
