SIRT1 protects against apoptosis by promoting autophagy in degenerative human disc nucleus pulposus cells
SIRT1 could protect degenerative human NP cells against apoptosis, and there were extensive and intimate connection between apoptosis and autophagy. Up to now, the role of autophagy in the process of human IVD degeneration is unclear. We sought to explore the relationship between autophagy and human IVD degeneration and to understand whether autophagy is involved in the protective effect of SIR...
متن کاملIntegrin β1 overexpression protects nucleus pulposus cells from apoptosis and attenuates intervertebral disc degeneration
Intervertebral disc (IVD) degeneration is a chronic pathologic process characterized by excessive apoptosis of intervertebral disc cells. The purpose of the current study was to detect the effect of integrin β1 on apoptosis of NP cells and IVD degeneration. Integrin β1 overexpressing lentivirus vector (LV-ITG β1) was constructed and transduced to NP cells, and its effect on cell apoptosis were ...
متن کاملRecombinant human SIRT1 protects against nutrient deprivation-induced mitochondrial apoptosis through autophagy induction in human intervertebral disc nucleus pulposus cells
INTRODUCTION Nutrient deprivation is a likely contributor to intervertebral disc (IVD) degeneration. Silent mating type information regulator 2 homolog 1 (SIRT1) protects cells against limited nutrition by modulation of apoptosis and autophagy. However, little evidence exists regarding the extent to which SIRT1 affects IVD cells. Therefore, we conducted an in vitro study using human IVD nucleus...
متن کاملIL-1β induces apoptosis and autophagy via mitochondria pathway in human degenerative nucleus pulposus cells
IL-1β has been reported highly expressed in degenerative intervertebral disc, and our previous study indicated IL-1β facilitates apoptosis of human degenerative nucleus pulposus (NP) cell. However, the underlying molecular mechanism remains unclear. We here demonstrate that IL-1β played a significantly pro-apoptotic effect under serum deprivation. IL-1β decreased Bcl-2/Bax ratio and enhanced cy...
متن کاملMesenchymal Stem Cells Protect Nucleus Pulposus Cells from Compression-Induced Apoptosis by Inhibiting the Mitochondrial Pathway
Objective Excessive apoptosis of nucleus pulposus cells (NPCs) induced by various stresses, including compression, contributes to the development of intervertebral disc degeneration (IVDD). Mesenchymal stem cells (MSCs) can benefit the regeneration of NPCs and delay IVDD, but the underlying molecular mechanism is poorly understood. This study aimed to evaluate the antiapoptosis effects of bone ...
