[Effect of glimepiride on the glucose uptake of rat mandibular osteoblasts in hyperglycemia].

AbstractOBJECTIVE:
To explore the effect of glimepiride on the glucose uptake as well as glucose transporter (GLUT)-1 and GLUT-3 expression levels of rat mandibular osteoblasts in hyperglycemia.
METHODS:
Primary osteoblasts were isolated and cultured. Then, the cells were placed in an osteogenic medium containing two glucose concentrations (5.5 and 16.5 mmol X L(-1)), with or without glimepiride (10 micromol x L(-1)). Glucose uptake was determined by employing 18F-deoxyglucose (18F-FDG) in the cells, and GLUT-1 and GLUT-3 expression levels were evaluated by Western blot analysis.
RESULTS:
Glucose at 16.5 mmol x L(-1) significantly inhibited 18F-FDG uptake and downregulated GLUT-3 protein expression in osteoblasts. Hyperglycemia increased GLUT-1 protein expression. Glimepiride significantly increased glucose uptake and upregulated GLUT-1 and GLUT-3.
CONCLUSION:
Glimepiride enhance the glucose transporter in rat osteoblasts at two different glucose concentrations.
