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.

With advances in our understanding of the pathogenesis of RA, the proliferative synovial tissues termed pannus at bone—cartilage interfaces consists of different inflammatory cells, including macrophages, osteoclasts and fibroblast-like synoviocytes FLSsthat contribute to the destructive process of affected joints in RA [ 1 ].

Data are representative of three independent experiments and expressed as mean s. Dickkopf-1 DKK-1 has been shown to be a major regulator of joint remodelling, which is associated with the bone erosion that occurs in different types of inflammatory arthritis such as RA [ 1011 ].


In addition, we found that WAYtreated and SPtreated RA FLSs exhibited significantly reduced expression of p-JNK and paxillin, in addition to reduced cell migration, although the off-target effect of these inhibitors could not be clearly excluded.
