Moreover, the addition of 20% dried plums into the normal diet of transgenic mice with induced-RA showed notable protective effects in protecting articular cartilage, reducing synovitis, IL-1β, MCP1, MIP1α, MMP1, and MPP3, and RANKL expression and repressing TNF-induced formation of osteoclasts and mRNA levels of cathepsin K and MMP9 by inhibiting nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1) expression, and NF-κB activation [360]. Here, MMP9 is linked to rheumatoid arthritis.
