The effects of osteoprotegerin on the mechanical properties of rat bone.

Abstract

Osteoprotegerin (OPG) is a naturally secreted protein that decreases bone resorption by inhibiting osteoclast differentiation and activation while promoting osteoclast apoptosis [8]. In this study, the effects of osteoprotegerin injections on long bone mechanical and material properties were investigated in young male Sprague-Dawley rats. OPG increased fracture strength at the femur mid-diaphysis in three-point bending by 30%, without affecting the elastic or maximum strength. At the femoral neck, OPG significantly increased the elastic (45%), maximum (15%), and fracture (35%) strengths. There was not a difference in microhardness at the femur mid-diaphysis in comparing the placebo and OPG groups. There were, however, significant increases in whole bone dry mass (25%), mineral mass (30%), organic mass (17%), and percent mineralization (4%); percent mineralization at the mid-diaphysis (3%); and percent mineralization at the distal epiphysis (6%) due to the OPG treatment. While OPG decreased endocortical bone formation (52%), total bone area, endocortical bone area, and periosteal bone formation were maintained with OPG treatment. A 30% increase in the X-ray opacity of the bone at the proximal metaphysis of the right tibiae was observed. Overall, OPG increased mineralization and strength indices in the rat femur. Its effects on strength were more pronounced in the femoral neck than at the mid-diaphysis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
