Enzymatic Behavior of Condoliase in Porcine Nucleus Pulposus: Ex Vivo and In Vitro Assessment [PDF]

JOR Spine
Background Condoliase is a treatment for lumbar disc herniation. This enzyme exerts its medicinal effects by digesting chondroitin sulfate (CS), which is abundant in the nucleus pulposus.

Damping properties of the nucleus pulposus [PDF]

Clinical Biomechanics, 2012
The nucleus pulposus is extremely deformable and it is not uncommon to observe strain amplitudes as large as 12.5% in physiological loading conditions. It has been shown that the nucleus pulposus contributes to the damping properties of the intervertebral disc.

MicroRNA-199a-5p accelerates nucleus pulposus cell apoptosis and IVDD by inhibiting SIRT1-mediated deacetylation of p21

Molecular Therapy: Nucleic Acids, 2021
Intervertebral disc degeneration (IVDD) is a multifactorial pathological process associated with low back pain in which nucleus pulposus cell senescence is disrupted.

Increased hemoglobin and heme in MALDI-TOF MS analysis induce ferroptosis and promote degeneration of herniated human nucleus pulposus

Molecular Medicine, 2021
Background Neovasculogenesis is characteristic of herniated lumbar discs, in which extruded nucleus pulposus is prone to heme iron-induced cytotoxicity (increased oxidative stress causing ferroptosis).

Inducing Angiogenesis in the Nucleus Pulposus

Cells, 2023
Bone morphogenetic protein (BMP) gene delivery to Lewis rat lumbar intervertebral discs (IVDs) drives bone formation anterior and external to the IVD, suggesting the IVD is inhospitable to osteogenesis. This study was designed to determine if IVD destruction with a proteoglycanase, and/or generating an IVD blood supply by gene delivery of an angiogenic

Vitamin D inhibits TNF-α induced apoptosis of human nucleus pulposus cells through regulation of NF-kB signaling pathway

Journal of Orthopaedic Surgery and Research, 2021
Background To observe the effects of vitamin D on the apoptotic human nucleus pulposus cells under tumor necrosis factor-α (TNF-α) treatment. Methods The gene expression data was downloaded from the NCBI Gene Expression Omnibus (GEO) database ( https ...

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.

Gene expression profiling in nucleus pulposus of human ruptured lumbar disc herniation

Frontiers in Pharmacology, 2022
Purpose: To examine the differences in gene expression between ruptured and non-ruptured nucleus pulposus tissues of the intervertebral discs using gene chip technology.Methods: A total of 8 patients with nucleus pulposus from a lumbar disc herniation ...

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,
