RANKL, also known as osteoclast differentiation factor (ODF), tumor necrosis factor - related activation-induced cytokine (TRANCE) and osteoprotegerin ligand, is a member of the TNF ligand family (106) produced in osteoblastic lineage cells and activated T cells
Slide 26: (OPG), also known as osteoclast inhibitory factor (OCIF) is a soluble decoy receptor for RANKL (111).
Skeleton Crew osteoclast The drugs target a protein called RANK Ligand, which helps regulate cells called osteoclasts that break down bone.
Incidentally, osteoclast is a type of cell that attacks the bone.
An osteoblast engaged in the absorption instead of the formation of bone is called an osteoclast.
When interference is called for, if the callus is not yet firmly consolidated, it may be possible, under an anæsthetic, to bend the bone into position or to re-break it, either with the hands or by means of a strong mechanical contrivance known as an osteoclast.
(C) Histomorphometric quantification of the trabecular bone volume and osteoclast surface per bone surface (OcS/BS).
Tnfrsf11b, the gene encoding the osteoclast-inhibitory factor Opg, is known to be induced by canonical Wnt signaling in osteoblasts
Col1a1-Krm2 mice display a cell-autonomous differentiation defect, impaired canonical Wnt signalling and decreased production of the osteoclast inhibitory factor Opg. To determine whether the observed effects of Krm2 on bone remodeling are physiologically relevant, we analyzed the skeletal phenotype of 24 weeks old
