#The present application is filed Pursuant to 35 U.S.C. 371 as a U.S. National Phase application of International Patent Application No. PCT/GB2006/001388, which was filed Apr. 18, 2006, claiming the benefit of priority of Great Britain Patent Application No. 0507874.6, which was filed on Apr. 19, 2005, and of Great Britain Patent Application No. 0507986.8, which was filed on Apr. 20, 2005.
#The present invention relates to the use of BiP in the manufacture of a composition for the prevention or treatment of bone loss or bone resorption. The present invention also relates to methods—such as diagnostic methods and assay methods—pharmaceutical compositions, transgenic animals and methods for preparing same.
#Dysregulated bone remodelling is a major part of the pathology of a number of diseases. In such conditions accelerated production and activation of the bone resorbing osteoclast population results from an as yet unidentified aberrant network of mediators. In the past ten years, the major signalling pathways and transcription factors controlling the commitment and differentiation of haematopoietic stem cells and monocyte/macrophage precursors to the osteoclast lineage, osteoclast proliferation and activation have been identified (1-5). It is now recognised that signalling via the constitutively expressed Receptor Activator of NF-κB (RANK) on osteoclast precursors following binding to RANK ligand (RANKL), in conjunction with activation by macrophage-colony stimulating factor (M-CSF), results in a complex series of events leading to the production of mature osteoclasts. In vivo both M-CSF and RANKL are provided by osteoblasts, which, together with the decoy receptor osteoprotegerin (OPG) (6-7), serve to regulate osteoclast differentiation and bone resorption. It is via the osteoblast component that systemic hormones and cytokines act indirectly to influence this process, with the relative ratio of RANKL to OPG critically controlling osteoclastogenesis. In pathological states (such as rheumatoid arthritis (RA)) however, RANKL can be provided additionally by activated T cells, fibroblast-like synoviocytes and other stromal cells (8-10). RANKL-RANK binding activates cell signalling cascades through several key stages. The process relies on the recruitment of TNF receptor-associated factor proteins (TRAFs), mitogen-activated protein kinase cascades (ERK, JNK and p38) in addition to Src- and phosphatidylinositol-3-kinase (PI3K) mediated activation of Akt, and all these RANK signalling pathways ultimately converge to activate several transcription factor families—such as NF-κB (11), activator protein-1 (AP-1) (12), particularly c-Fos (13), and Nuclear Factor of Activated T cells (NFAT), specifically NFATc1 (1;5;14;15). That these signalling molecules and transcription factors have essential roles in osteoclast differentiation and activation has been demonstrated unequivocally in loss-of-function mouse mutants in vivo (5).
#BiP.FITC binding to peripheral blood monocytes. Human serum albumin.FITC (solid) or BiP.FITC (open) were used to stain human monocytes for 20 mins at 4° C. and the fluorescence measured by flow cytometry. The FACscan histogram was generated using Cellquest software.
#As used herein, the term “BiP” refers to the 78 kD endoplasmic reticulum chaperone protein as disclosed in WO 00/21995. Preferably the BiP polypeptide has the amino acid sequence as shown in appendix 2 of WO00/21995 at page 23.
