Peroxisome proliferator-activated receptors (PPARs) are members of the nuclear steroid hormone superfamily and exist in three isoforms: PPARα, β and γ, each with specific functions. In this study, we have investigated the expression of PPARs by human osteoclast precursors and osteoclasts generated in vitro. In addition, the effects of fibrates and isoform-specific PPAR agonists on osteoclast formation...
Nucleotides such as adenosine triphosphate (ATP) and uridine triphosphate (UTP) exist in the extracellular environment where they are agonists at P2 receptors. Both P2Y G-protein-coupled receptors and P2X ligand-gated ion channels are expressed by osteoblasts and osteoclasts, reflected in the diverse nucleotide-induced effects reported to occur in bone. Previous reports have implicated ATP as a proresorptive...
Bone turnover occurs at discreet sites in the remodeling skeleton. The focal nature of this process indicates that local cues may facilitate the activation of bone cells by systemic factors. Nucleotides such as adenosine triphosphate (ATP) are locally released, short-lived, yet potent extracellular signaling molecules. These ligands act at a large family of receptors-the P2 receptors, which are subdivided...
The presence of intranuclear inclusions in pagetic osteoclasts with similar characteristics to those seen in some slow viral diseases has lead to the hypothesis that Paget's disease is caused by a similar infection. Bone marrow aspirates from seven patients with hemipelvic Paget's disease were taken from both sides of the pelvis and cultured under identical conditions. RNA was extracted after approximately...
