Fig. 4From: Silymarin modulates catabolic cytokine expression through Sirt1 and SOX9 in human articular chondrocytesModulation of anabolic and catabolic cytokines by SMN. ELISA assays revealed that treatment with 25 μM SMN reduced the production of catabolic cytokine-stimulated IL-1β, TNF-α, MMP-3 and MMP-9 and increased the production of TIMP-1 in the injured chondrocytes. However, the levels of IL-6, IL-8, IL-10 and TIMP-2 proteins remained unaltered upon SMN additionBack to article page
