Figure 1From: Constitutive expression of cathepsin K in the human intervertebral disc: new insight into disc extracellular matrix remodeling via cathepsin K and receptor activator of nuclear factor-κB ligandCathepsin K expression and stages of disc degeneration. Cathepsin K gene expression was significantly greater in annulus tissue from more degenerated discs than in healthier discs (P = 0.001). Data are means ± s.e.m.Back to article page
