To investigate the relationship between inflammatory arthritis and Pim2 expression, we analyzed public data (GEO36700) to determine the mRNA levels of Pim2 in patients with various forms of arthritis, including serum-negative arthritis, microcrystalline arthritis, SLE-related arthritis, osteoarthritis (OA), and rheumatoid arthritis (RA). Here, PIM2 is linked to osteoarthritis.
