This miRNA has been i.a. linked with such rheumatic diseases-relevant processes as enhancing osteogenesis of human mesenchymal stem cells (32), inhibiting IL-17-induced monocyte chemoattractant protein-1 (MCP1) expression (33) or suppressing the NF-κB signaling pathway in osteoarthritic chondrocytes (34). The gene discussed is CCL2; the disease is rheumatic disorder.
