Description
Introduction Disorders that affect glucose metabolism, namely
diabetes mellitus (DM), may favor the development and/or
progression of osteoarthritis (OA). Thus far, little is known
regarding the ability of chondrocytes to adjust to variations in the
extracellular glucose concentration, resulting from hypoglycemia
and hyperglycemia episodes, and so, to avoid deleterious
effects resulting from deprivation or intracellular accumulation of
glucose. The aim of this study was to compare the ability of
normal and OA chondrocytes to regulate their glucose transport
capacity in conditions of insufficient or excessive extracellular
glucose and to identify the mechanisms involved and eventual
deleterious consequences, namely the production of reactive
oxygen species (ROS). 1Center for Neurosciences and Cell Biology, and Faculty of Pharmacy, University of Coimbra, 3004-517 Coimbra, Portugal
