Sirt1 protects against intervertebral disc degeneration induced by 1,25-dihydroxyvitamin D insufficiency in mice by inhibiting the NF-κB inflammatory pathway

Journal of Orthopaedic Translation, 2023
Background: It has been demonstrated that vitamin D deficiency is associated with an increased risk of patients developing lumbar disc herniation. However, intervertebral disc degeneration caused by active vitamin D deficiency has not been reported. Thus,

Osmotic adaptation of nucleus pulposus cells: the role of aquaporin 1, aquaporin 4 and transient receptor potential vanilloid 4 [PDF]

European Cells & Materials, 2021
The microenvironment of the nucleus pulposus is hyperosmotic and fluctuates diurnally due to mechanical loading. Changes in extracellular osmolality result in cell volume alterations, responsiveness to such changes is essential for cellular homeostasis ...

Integrated transcriptome and proteome analyses identify novel regulatory network of nucleus pulposus cells in intervertebral disc degeneration

BMC Medical Genomics, 2021
Background Degeneration of intervertebral disc is a major cause of lower back pain and neck pain. Studies have tried to unveil the regulatory network using either transcriptomic or proteomic analysis.

The responses of nucleus pulposus cells to pressure and ultrasound stimulation [PDF]

The Journal of the Acoustical Society of America, 2020
A cellular stimulation device with a pressurized chamber is developed to investigate the effect of ultrasound and pressure fluctuation on nucleus pulposus (NP) cells. The pressurized chamber is designed to emulate the in vivo environment of intervertebral discs, which are under dynamic pressure, and to emulate impact during sports and exercise.

Nucleus Pulposus Cell Conditioned Medium Promotes Mesenchymal Stem Cell Differentiation into Nucleus Pulposus-Like Cells under Hypoxic Conditions [PDF]

Stem Cells International, 2020
Low back pain (LBP) is a major physical and socioeconomic challenge worldwide. Nucleus pulposus (NP) is directly associated with LBP due to intervertebral disc (IVD) degeneration. IVD degeneration is mainly caused by structural and matrix-related changes within the IVD occurring during aging and degeneration.
