SIRT1 mRNA and protein expression in nucleus pulposus cells. (a) Silent mating type information regulator 2 homolog 1 (SIRT1) mRNA expression in human nucleus pulposus (NP) cells. Results of RT-PCR on NP cells derived from disc tissues of patients with lumbar spinal stenosis, lumbar disc herniation and idiopathic scoliosis are shown. (b) SIRT1 protein distribution in NP cells. Immunohistochemical staining of NP cells for β-actin (A) and SIRT1 (B) (images are merged in C). Bars = 15 μm. GAPDH, glyceraldehyde 3-phosphate dehydrogenase.
