Osteoclast differentiation and activation

Nature, 2003
Osteoclasts are specialized cells derived from the monocyte/macrophage haematopoietic lineage that develop and adhere to bone matrix, then secrete acid and lytic enzymes that degrade it in a specialized, extracellular compartment. Discovery of the RANK signalling pathway in the osteoclast has provided insight into the mechanisms of osteoclastogenesis ...

Regulation of Differentiated Osteoclasts

Critical Reviews in Eukaryotic Gene Expression, 2000
Osteoclasts respond to many factors, including endocrines, cytokines, cell-cell interactions, and cell-matrix contacts. For mature osteoclasts, the first level of control occurs through signaling that follows binding to an appropriate substrate. Mononuclear and multinucleate osteoclasts are activated when cell surface integrins, notably but not ...

Control of Osteoclast Differentiation

Critical Reviews™ in Eukaryotic Gene Expression, 1998
The osteoclast is the primary bone-resorbing cell and is derived from the monocyte/macrophage lineage. Bipotent osteoclast precursors, which can form both osteoclasts and monocyte-macrophages, proliferate and differentiate to become unipotent post-mitotic committed osteoclast precursors.

Modulation of Osteoclast Differentiation

Endocrine Reviews, 1992
I. Introduction BONE is a complex tissue in which resorption and formation continue throughout life. This process is called bone remodeling. Osteotropic hormones such as 1α,25-dihydroxyvitamin D3 [1α,25(OH)2D3], PTH, and calcitonin preferentially modulate the process of bone resorption to maintain bone remodeling. The bone tissue contains various types

Osteoclast differentiation factor induces synovial macrophage–osteoclast differentiation in rheumatoid arthritis

Modern Rheumatology, 2001
Abstract The aim of this study was to clarify the role of osteoclast differentiation factor (ODF) and osteoprotegerin (OPG) in synovial macrophage-osteoclast differentiation. Synovial macrophages were cultured in the presence of macrophage-colony-stimulating factor (M-CSF) and/or ODF. OPG was added to cocultures of synovial macrophages and UMR106.

Proteasome inhibitors abrogate osteoclast differentiation and osteoclast function

Biochemical and Biophysical Research Communications, 2005
Cancer-induced bone disease results in bone destruction, pathological fractures, and pain. We hypothesized that the inhibition of the proteasome-ubiquitin system in osteoclasts could abolish the receptor activator of NF-kappaB ligand (RANKL) mediated osteoclast differentiation and function, since RANKL-mediated downstream signaling plays a crucial role
