Abstract Background Intervertebral disc degeneration (IDD) is a progressive age‐related disorder characterized by the reduction in number of nucleus pulposus cells (NPCs) and degradation extracellular matrix (ECM), thereby leading to chronic pain disability. The pathogenesis IDD multifaceted, current therapeutic strategies remain limited. (NP), primarily composed NPCs, proteoglycans, type II collagen, constitutes essential components for maintaining intervertebral (IVD) function spinal motion. disturbed homeostasis NPCs closely associated with IDD. Accumulating evidence increasingly suggests crucial role programmed cell death (PCD) regulating NPCs. Aims This review aimed elucidate various forms PCD their respective roles IDD, investigate diverse targeting treatment. Materials & Methods We collected relevant literature regarding development Subsequently, we comprehensively summarized intricate association between also explored potential application therapy traditional Chinese medicine (TCM) prevention treatment Results Current indicated that was Additionally, targeted pharmaceuticals based on mechanisms could effectively impede loss Conclusion demonstrated may be promising strategy

Lipid metabolism is a complex process that maintains the normal physiological function of human body. The disorder lipid has been implicated in various diseases, such as cardiovascular diseases and bone diseases. Intervertebral disc degeneration (IDD), an age-related degenerative disease musculoskeletal system, characterized by high morbidity, treatment cost, chronic recurrence. may promote pathogenesis IDD, potential mechanisms are complex. Leptin, resistin, nicotinamide phosphoribosyltransferase (NAMPT), fatty acids, cholesterol while lipocalin, adiponectin, progranulin (PGRN) exhibit protective activity against IDD development. contributes to extracellular matrix (ECM) degradation, cell apoptosis, cartilage calcification intervertebral discs (IVDs) activating inflammatory responses, endoplasmic reticulum (ER) stress, oxidative stress inhibiting autophagy. Several lines agents have developed target disorder. Inhibition be effective strategy for therapeutic management IDD. However, in-depth understanding molecular mechanism promoting development still needed.

This study explored the role of ferroptosis in intervertebral disc degeneration (IVDD), and identified GATA6 as a key regulator this process. A ferroptosis-related gene risk coefficient model was constructed using differential expression analysis GSE70362 dataset. The significant factor IVDD progression. shown to promote nucleus pulposus cells (NPCs) by regulating AKR1C3 through TLR2 pathway. In vitro vivo experiments demonstrated that knockdown reduced ferroptosis, improved cell viability, mitigated extracellular matrix degradation, whereas overexpression exacerbated these processes. Furthermore, found be crucial for GATA6-mediated modulation TLR2-AKR1C3 axis significantly impacted NPCs. These findings suggest targeting its downstream pathway may provide new therapeutic approaches IVDD.

Oxeiptosis is a reactive oxygen species (ROS)-induced pathway of cell death. The involvement circular RNAs (circRNAs) has been confirmed in the incidence and progression intervertebral disc degeneration (IVDD). However, whether oxeiptosis occurs IVDD how circRNAs regulate still unclear. In this study, we discovered that could be induced nucleus pulposus cells (NPCs), circFOXO3 was significantly upregulated after induction. Transfection using small interfering RNA (siRNA) inhibited NPCs. Mechanistically, acid-sensing ion channel subunit 1 (ASIC1) expression by functioning as molecular sponge for miR-185-3p miR-939-5p. Subsequent rescue experiments validated NPCs via miR-185-3p/miR-939-5p-ASIC1 axis. Further research on ASIC1 functions indicated regulation achieved affecting Calcium (Ca2+) influx mediated ASIC1. A mouse model established, silencing vivo found to inhibit development activation oxeiptosis-related pathway. Overall, one factors contributing mediating oxeiptosis.

Intervertebral disc degeneration (IDD) is a major cause of low back pain (LBP), and effective therapies are still lacking. Reactive oxygen species (ROS) stress induces NLRP3 inflammasome activation, this, along with extracellular matrix metabolism (ECM) degradation in nucleus pulposus cells (NPCs), plays crucial role the progression IDD. Daphnetin (DAP) biologically active phytochemical extracted from plants Genus Daphne, which possesses various bioactivities, including antioxidant properties. In present study, we demonstrate that DAP significantly attenuates tert-butyl hydroperoxide (TBHP)-induced ECM degradation, oxidative activation NPCs. Furthermore, could facilitate mitophagy to increase removal damaged mitochondria, consequently reducing mitochondrial ROS accumulation alleviating activation. Mechanistically, unveil activates by stimulating Nrf2/PINK1 signaling pathway TBHP-induced vivo experiments further corroborate protective effect against IDD rat model induced puncture. Accordingly, our findings reveal be promising therapeutic candidate for treatment
