This is an important contribution, adding to the understanding of bone remodeling, which is not just relevant to arthritis but also to degenerative bone changes. Degenerative and inflammatory joint diseases lead to a destruction of the joint architecture. Whereas degenerative osteoarthritis results in the formation of new . Figure 3 New bone formation next to inflamed joints is increased upon blockade of DKK (a) Microphotographs of toluidine blue–stained joint sections of, ”from.

Secreted frizzled-related protein 5 suppresses inflammatory response in rheumatoid arthritis fibroblast-like synoviocytes through down-regulation of c-Jun N-terminal kinase. Focal adhesion kinase is required for synovial fibroblast invasion, but not murine inflammatory arthritis.
A rate-limiting role for Dickkopf-1 in bone formation and the remediation of bone loss in mouse and primate models of postmenopausal osteoporosis by an experimental therapeutic antibody.
This paper has highly influenced 44 other papers. Adenoviral overexpression of Smad-7 and Smad-6 differentially regulates TGF-beta-mediated chondrocyte proliferation and proteoglycan synthesis. Of these protein tyrosine kinases, FAK plays a prominent role in integrin signalling and has been implicated in a diverse array of cellular processes, including cell migration, growth factor signalling and cell survival [ 19 ].
Specifically, JNK-mediated phosphorylation of serine in paxillin was shown to be required for enhanced cell migration [ 21 ].

User comments must be in English, comprehensible and relevant to the article under discussion. Cell migration was shown to be increased in both human primary hepatocellular cells and immortalized HEK cells overexpressing DKK-1 [ 1314 ], whereas the opposite effect was observed in studies with thyroid cancer and intestinal epithelial cells [ 1416 ]. The increased mobility of RA FLSs has also been shown to significantly aggravate this inflammation and bone destruction [ 2—52829 ].
These discrepancies might result from the variety of diseases and cellular conditions that have been studied. He Therapeutic advances in musculoskeletal disease Showing of 34 references. Whereas degenerative osteoarthritis results in the formation of new bone, rheumatoid arthritis leads to bone resorption. Recently, conflicting evidence has been obtained regarding the role of DKK-1 in cell migration.
The molecular basis of these different patterns of joint disease is unknown.
