From: The role of interleukin-1 in the pathogenesis of human Intervertebral disc degeneration
Effect of IL-1 treatment on the IL-1 family gene expression in human intervertebral disc cells. Relative gene expression was normalized to glyceraldehyde-3-phosphate dehydrogenase (GAPDH) housekeeping gene and untreated controls (hence control is graphed at 1 on the log scale) for IL-1α (a), IL-1β (b), IL-1 receptor antagonist (IL-1Ra) (c), and IL-1 receptor, type I (IL-RI) (d) following IL-1β treatment of disc cells from two regions of non-degenerate (non-deg) (n = 6) and degenerate (n = 24) discs. **P < 0.05.
