Background & Aim: Low back pain is broadly documented as one of the most widespread pathologies in the advanced domain. Although the reasons of low back pain are uncountable, it has been meaningfully related to intervertebral disc degeneration. Present therapies for Intervertebral Disc (IVD) degeneration such as physical therapy and spinal fusion reduce symptoms' severity, but do not treat the ...

BACKGROUND Intervertebral disc degeneration has an annual worldwide socioeconomic impact masked as low back pain of over 70 billion euros. This disease has a high prevalence over the working age class, which raises the socioeconomic impact over the years. Acute physical trauma or prolonged intervertebral disc mistreatment triggers a biochemical negative tendency of catabolic-anabolic balance th...

BACKGROUND Degenerative disc disease of the lumbar spine is common, with severe disease increasing the risk for chronic low back pain. This cross-sectional study examined whether disc degeneration is representative of a 'whole-organ' pathology, by examining its association with bone (vertebral endplate) and soft tissue (paraspinal muscle fat) abnormalities. METHODS Seventy-two community-based...

Atsttrin, an engineered molecule composed of three fragments of progranulin(PGRN), exerts comparable anti-inflammation ability. Intervertebral disc degeneration (IDD) is involved in inflammation in which TNF-α plays a key role. This study aims to examine the effect and the mechanism of Atsttrin in the pathogenesis of intervertebral disc degeneration. For this purpose, we took advantage of murin...

Intervertebral disc degeneration is the main cause of lumbago disease, in which the extracellular matrix structure and moisture in the nucleus pulposus is lost continuously. In this study, we aimed to detect differential expression of silence mating type information regulation 2 homolog 1 (SIRT1) and matrix metalloproteinase-1 (MMP-1) in human intervertebral disc nucleus pulposus cells and to e...

The ability of the nucleus pulposus of the intervertebral disc to resist compressive loads is due to its high content of the proteoglycan aggrecan. Degeneration of the intervertebral disc is preceded and accompanied by a loss of aggrecan due to proteolysis. Biological repair of intervertebral disc degeneration should strive to restore aggrecan content to its optimal functional level. One approa...

OBJECTIVE To evaluate the structural and molecular changes in the extracellular matrix (ECM) during the process of intervertebral disc degeneration, using animal model. METHODS Wistar rats underwent intervertebral disc degeneration through 20-gauge needle puncture, and 360° rotation applied for 30 sec, representing the degenerated group, while control group was not submitted to this procedure...

objective(s): activation of acid-sensing ion channel 1a (asic1a) is responsible for tissue injury caused by acidosis in nervous systems. but its physiological and pathological roles in nucleus pulposus cells (npcs) are unclear. the aim of this study is to investigate whether asic1a regulates the survival of npcs in the acidic environment of degenerated discs. materials and methods: npcs were is...

OBJECTIVE Although the etiology of intervertebral disc degeneration is poorly understood, one possible approach for its regulation is apoptosis inhibition. This study was undertaken to investigate the antiapoptotic effects of caspase 3 in intervertebral disc degeneration in rabbits. METHODS We investigated the effects of caspase 3 small interfering RNA (siRNA) on rabbit nucleus pulposus cells...

Degeneration of the lumbar intervertebral discs is irreversible, with no treatment currently available. Building upon experimental studies that demonstrated the importance of the nucleus pulposus (NP) in preserving disc structure, we demonstrated that reinsertion of NP cells slowed further disc degeneration and that direct cell-to-cell contact co-culture with mesenchymal stromal cells (MSCs) si...
