TRAIL inhibits osteoclastic differentiation by counteracting RANKL‐dependent p27Kip1 accumulation in pre‐osteoclast precursors

Abstract

Experimental evidences indicate that the TNF family member TNF‐related apoptosis inducing ligand (TRAIL) might be involved in modulating osteoclastic differentiation. The ability of recombinant soluble TRAIL to affect bone density in vivo was evaluated by using 4‐week‐old mice subcutaneously (s.c.) injected with TRAIL for 8 days. TRAIL injection induced a significant increase of tibia trabecular thickness and total bone mass in 4‐week‐old mice, accompanied by a significant decrease of TRAP serum levels, without modulation of osteocalcin and osteoprotegerin (OPG). Parallel experiments performed in vitro showed that inhibition of osteoclastic differentiation, induced by treatment of human peripheral blood osteoclast precursors with TRAIL, was associated to inhibition of receptor activator of nuclear factor kappa B ligand (RANKL)‐induced accumulation of p27 Kip1. The potential role of p27 Kip1 pathway in mediating the anti‐osteoclastic activity of TRAIL was further suggested by in vitro gene knock‐down experiments performed in osteoclast precursor cultures. Taken together, our data strongly suggest that recombinant TRAIL inhibits osteoclastogenesis by inducing the ubiquitin‐mediated degradation of p27 Kip1. J. Cell.

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.
