[Fibulin-3 Regulates Tissue Inhibitor of Metalloproteinases 3 to Inhibit Senescence in Intervertebral Disc Nucleus Pulposus Cells].

Objective: To investigate the effect of fibulin-3 on the senescence of intervertebral disc nucleus pulposus cells (NPCs) through the regulation of tissue inhibitor of metalloproteinases 3 (TIMP-3) expression and to elucidate the molecular mechanisms involved.

Methods: 1). The nucleus pulposus tissues and imaging data of 37 patients who had undergone intervertebral disc surgery were collected.

Indole-3-acetic acid enhances the co-transport of proton and phenanthrene mediated by TaSAUR80-5A in wheat roots.

Polycyclic aromatic hydrocarbons (PAHs) are a type of organic pollution that can accumulate in crops and hazard human health. This study used phenanthrene (PHE) as a model PAH and employed hydroponic experiments to illustrate the role of indole-3-acetic acid (IAA) in the regulation of PHE accumulation in wheat roots. At optimal concentrations, wheat roots treated with PHE + IAA showed a 46.

Identifying the protective effects of miR-874-3p/ATF3 axis in intervertebral disc degeneration by single-cell RNA sequencing and validation.

Intervertebral disc degeneration (IVDD) severely affects the work and the quality of life of people. We previously demonstrated that silencing activation transcription factor 3 (ATF3) blocked the IVDD pathological process by regulating nucleus pulposus cell (NPC) ferroptosis, apoptosis, inflammation, and extracellular matrix (ECM) metabolism. Nevertheless, whether miR-874-3p mediated the IVDD pathological process by targeting ATF3 remains unclear.

Silencing ATF3 Might Delay TBHP-Induced Intervertebral Disc Degeneration by Repressing NPC Ferroptosis, Apoptosis, and ECM Degradation.

Intervertebral disc degeneration (IDD), being the predominant root cause of lower back pain, has led to an enormous socioeconomic burden in the world. Ferroptosis is an iron-dependent nonapoptotic and nonpyroptotic programmed cell death associated with an increase in reactive oxygen species (ROS), which has been implicated in the pathogenesis of IDD. Activation transcription factor 3 (ATF3) is widely reported to promote ferroptosis and apoptosis in multiple diseases, but its roles and underlying regulatory mechanism in IDD have not been identified.

Circ_0004354 might compete with circ_0040039 to induce NPCs death and inflammatory response by targeting miR-345-3p-FAF1/TP73 axis in intervertebral disc degeneration.

The abnormal function of nucleus pulposus cells (NPCs) plays a crucial role in the pathogenesis of intervertebral disc degeneration (IVDD). Recent studies have demonstrated that circular RNAs (circRNAs) are involved in the pathological process of IVDD by regulating NPCs' function. Nevertheless, the investigation on circRNA-circRNA interaction has not yet been reported.

Circ_0040039 May Aggravate Intervertebral Disk Degeneration by Regulating the MiR-874-3p-ESR1 Pathway.

The functional alteration of nucleus pulposus cells (NPCs) exerts a crucial role in the occurrence and progression of intervertebral disk degeneration (IDD). Circular RNAs and microRNAs (miRs) are critical regulators of NPC metabolic processes such as growth and apoptosis. In this study, bioinformatics tools, encompassing Gene Ontology pathway and Venn diagrams analysis, and protein-protein interaction (PPI) network construction were used to identify functional molecules related to IDD.

Emerging role of circular RNA in intervertebral disc degeneration: Knowns and unknowns (Review).

Lower back pain (LBP) is one of the predominant factors contributing to dyskinesia and remains a serious social and economic burden worldwide. Intervertebral disc degeneration (IDD) is the leading cause of LBP; the existing IDD treatments cannot completely prevent IDD. Circular RNAs (circRNAs) are non‑coding RNAs resulting from back‑splicing with unique structural characteristics and functions.

Epidemiology of traumatic spinal fractures: experience from medical university-affiliated hospitals in Chongqing, China, 2001-2010.

Object: The main objective of this study was to analyze the epidemiological data obtained from patients with traumatic spinal fracture at 2 university-affiliated hospitals in Chongqing, China.

Methods: The authors retrospectively reviewed the hospital records of all patients who suffered traumatic spinal fracture and were treated at Xinqiao Hospital and Southwest Hospital (both affiliated with The Third Military Medical University) between January 2001 and December 2010. The demographic characteristics, injury characteristics, and clinical outcomes of patients over this 10-year period were compared.
