Figure 6

Bone remodelling in the CIA model. Model of bone remodelling during the course of clinical arthritis. The proposed dominating process in the bone is shown in the top part of the figure. Differentially expressed genes, encoding proteins with a function in bone remodelling, are divided into groups according to function and time point of highest differential expression in comparison to the control. All genes are upregulated in comparison to the control at the indicated time-point. Group 1: genes encoding proteins involved in osteoclast function and differentiation; Group 2: genes encoding proteins with a function in extracellular matrix formation and collagen type I assembly (highest differential expression at day 0 to 4); Group 3: genes encoding proteins with a function in extracellular matrix formation and collagen type I assembly (sustained high differential expression on day 0 to 4 and week 1 to 2); Group 4: genes with a function in mineralisation of bone (highest differential expression in week 1 to 2); Group 5: genes with a function in mineralisation of bone (highest differential expression during week 3 to 4). CIA, collagen-induced arthritis; ECM, extracellular matrix.
