Abstract

The purpose of this study was to investigate the effect of zoledronate (ZA) on osteoclast functions and viability in the tibiae of 8-week-old male mice. After weekly intravenous administration of ZA (125 μg/kg body weight) for 8 weeks, the mice were fixed by transcardial perfusion of 4% paraformaldehyde under anesthesia, and their tibiae were extracted for histochemical analysis. Compared with the control group, many tartrate-resistant acidic phosphatase-positive osteoclasts were found on the surface of the trabecular bone, but cartilage cores were obviously increased in the metaphysis of the ZA group. Osteoclasts of both groups showed similar expression of cathepsin K and matrix metalloproteinase-9. However, hardly any expression of c-src, a gene necessary for ruffled border formation and bone resorption, was found in osteoclasts of the ZA group. Moreover, no expression of CD44 or osteopontin (OPN) was observed in osteoclasts of the ZA group. Taken together, our findings suggest that ZA administration decreases the bone resorption ability of osteoclasts by inhibiting c-src expression and suppressing osteoclast adhesion by interfering with CD44/OPN binding.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • NBPs induce osteoclasts to acquire a nonresorbing phenotype by inhibiting c-Src and stimulating DC-STAMP.

    “NPBs induce osteoclasts to acquire a nonresorbing phenotype by inhibiting c-Src, which is essential for cytoskeletal construction,158 and by stimulating dendritic cell-specific transmembrane protein (DC-STAMP),159 which is necessary for cell fusion.”

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.
