Schematic representation of correlations between pro-inflammatory cytokines, osteoclasts-specific genes, bone mineral density and levels of bone turnover markers in osteoporosis and osteoarthritis, according to results of Zupan et al. (146).
(−) - denotes negative correlation; (+) - denotes positive correlation; BMD - bone mineral density; RANK/RANKL/OPG - the most significant correlations of pro-inflammatory cytokines with RANK, RANKL and OPG genes are shown; sCathepsin K - cathepsin K serum levels; sOPG - OPG serum levels; sRANKL - RANKL serum levels; OSCAR - osteoclast-associated immunoglobulin-like receptor; CALCR - calcitonin receptor; TRAP - tartrate-resistant acid phosphatase.
