MicroRNA-494 promotes apoptosis and extracellular matrix degradation in degenerative human nucleus pulposus cells
PURPOSE This study investigated the expression and function of the microRNA-494 in intervertebral disc degeneration (IDD). RESULTS MicroRNA-494 expression was upregulated during IDD progression; its overexpression increased the expression of ECM catabolic factors such as matrix metalloproteinase and A disintegrin and metalloproteinase with thrombospondin motif in NP cells while decreasing tha...
متن کاملLow Intensity Pulsed Ultrasound Promotes the Extracellular Matrix Synthesis of Degenerative Human Nucleus Pulposus Cells Through FAK/PI3K/Akt Pathway.
STUDY DESIGN In vitro experimental study. OBJECTIVE To investigate the effect of low-intensity pulsed ultrasound (LIPUS) on the extracellular matrix (ECM) synthesis of degenerative human nucleus pulposus cells and explore the molecular mechanism. SUMMARY OF BACKGROUND DATA LIPUS has been used successfully for bone fracture healing and been proved to be effective in stimulating ECM metabolis...
متن کاملIntegrin-mediated interactions with extracellular matrix proteins for nucleus pulposus cells of the human intervertebral disc.
The extracellular matrix (ECM) of the human intervertebral disc is rich in molecules that interact with cells through integrin-mediated attachments. Porcine nucleus pulposus (NP) cells have been shown to interact with laminin (LM) isoforms LM-111 and LM-511 through select integrins that regulate biosynthesis and cell attachment. Since human NP cells lose many phenotypic characteristics with age...
متن کاملSIRT1 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 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...
