Abstract

Osteoarthritis (OA) and rheumatoid arthritis (RA) are the most prevalent forms of arthritis in the elderly. This study aimed to explore the molecular mechanisms of these diseases and identify underlying therapeutic targets. Using GSE1919 microarray data sets downloaded from the Gene Expression Omnibus database, we screened differentially expressed genes (DEGs) in OA and RA cells. The underlying molecular mechanisms of these crucial genes were investigated by Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis. Small molecule expression and SNP analysis were also conducted by searching CMap and dbSNP databases. More than 320 genes changed in the arthritic cells and there were only 196 DEGs between OA and RA. OA and RA activated the classic mitogen-activated protein kinase signaling pathway, insulin signaling pathway, antigen processing and presentation and intestinal immune network for IgA production. Graft-versus-host disease and autoimmune thyroid disease-related pathways were also activated in OA and RA. Parthenolide and alsterpaullone may be treatments for OA and RA and insulin-like growth factor 1, collagen α2(I) chain and special AT-rich sequence-binding protein 2 may be critical SNP molecules in arthritis. Our findings shed new light on the common molecular mechanisms of OA and RA and may provide theoretical support for further clinical therapeutic studies.
