Abstract

Skeletal changes accompanying aging are associated with both increased risk of fractures and impaired fracture healing, which, in turn, is due to compromised bone regeneration potential. These changes are associated with increased serum levels of selected proinflammatory cytokines, e.g., tumor necrosis factor α (TNF-α). We have used a unique model of bone regeneration to demonstrate (1) that aged-related deficits in direct bone formation can be restored to young mice by treatment with TNF blockers and (2) that the cyclin-dependent kinase inhibitor p21 is a candidate for mediation of the osteoinhibitory effects of TNF. It has been hypothesized recently that TNF antagonists may represent novel anabolic agents, and we believe that the data presented here represent a successful test of this hypothesis. © 2010 American Society for Bone and Mineral Research

  • Use of TNF-α and TNF-β blockers in aged mouse model accelerates fracture healing.

    “the use of TNF-α and TNF-β blockers in the aged mouse model can accelerate the healing of mouse fractures [89].”

    From Modulation of fracture healing by senescence-associated secretory phenotype (SASP): a narrative review of the current literature (2024) · cites this paper as [89]

    The Results (Study 2; page unavailable) show that two TNF blockers increased new bone formation in aged mice. The Introduction describes the distraction-osteogenesis model as a variant of fracture healing, but the study did not directly show faster healing of mouse fractures. It also identifies the treatments as TNF-receptor-derived blockers, rather than separately demonstrating effects of TNF-α and TNF-β blockers. (LLM, conf=0.88)

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.
