DICKKOPF-1 IS A MASTER REGULATOR OF JOINT REMODELING PDF

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.

The molecular basis of these different patterns of joint disease is unknown. Conflicting results regarding the role of DKK-1 in cell migration have been described in different cell types, including hepatocellular carcinoma cells [ 13 ], intestinal epithelial cells [ 14 ], HEK cells [ 15 ] and thyroid cancer cells [ 16 ]. Hypoxia upregulates angiogenesis and synovial cell migration in rheumatoid arthritis.

Showing of 34 references. Moreover, the distances between the migration fronts of control and SPtreated RA FLSs were also significantly different at 6, 24 and 48 h. Integrins are cell surface adhesion receptors that link the cell surface to the extracellular matrix ECM or to other cells.
