Figure 4From: Expression of silent mating type information regulator 2 homolog 1 and its role in human intervertebral disc cell homeostasis Effect of exogenous SIRT1 on the extracellular matrix metabolism of nucleus pulposus cells. mRNA expression of (a) aggrecan, (b) Sox9 and (c) collagen type 2 following treatment with recombinant human silent mating type information regulator 2 homolog 1 (rhSIRT1). Data were obtained from 11 patients (six lumbar spinal stenosis and lumbar disc herniation patients, and five idiopathic scoliosis patients).
