Abstract:
... Intervertebral disc degeneration (IDD) is a kind of disease associated with nucleus pulposus (NP) cell senescence. Previous studies have shown that the sirtuin family plays an extremely important role in the progress of cell aging. However, whether sirtuin2 (Sirt2) protects against IDD remains unknown. The aim of this study was to determine whether Sirt2 protected NP from degradation in IDD. The e ...
