In the present study, we selected the following genes, sclerostin (Sost), low density lipoprotein receptor-related protein 6 (Lrp6), transcription factor 7-like 2 (Tcf7l2), alkaline phosphatase (Alpl), Mitogen-activated protein kinase kinase 6 (Map2k6) and nuclear factor of activated T cells, cytoplasmic, calcineurin dependent 4 (Nfatc4) involved in the significant signaling pathway “role of osteoblasts, osteoclasts, and chondrocytes in rheumatoid arthritis” (Figure 4) for additional evaluation. This evidence concerns the gene ALPL and rheumatoid arthritis.
