Summary

Some possible humoural and cellular mechanism for diabetes related osteoporosis/fractures were proposed and summarzied as the following, (1)Diabetes mellitus increases osteoclast function but decreases osteoblast function, thereby leading to accelerated bone loss, osteopenia and osteoporosis. (2)DM/hyperglycemia induces production of macrophage colony stimulating factor (MCSF), tumor necrosis factor (TNF)-α and receptor activator of nuclear factor-κB ligand (RANKL), all of which are osteoblast-derived activators of osteoclast proliferation and differentiation. (3) DM/hyperglycemia suppresses osteoblast proliferation and function, in part, by decreasing runtrelated transcription factor (Runx)-2, osteocalcin and osteopontin expressions. (4)Adipogenic differentiation of mesenchymal stem cells is increased as indicated by the overexpression of adipocyte differentiation markers, including peroxisome proliferator-activated receptor (PPAR)-g, adipocyte fatty acid binding protein (aP2), adipsin and resistin. A decrease in neovascularization may further aggravate bone loss. (5)Bone quality is also reduced as a result of advanced glycation end products (AGE) production, which may eventually result in low impact or fragility fractures. DM are associated osteoporosis/fracture. The underlying mechanism, especially of type 2 DM, mandates a DM-osteoporosis cohort to elucidate. In clinical practice, to developed preventive strategies from osteoporotic-fracture is also necessary.
