Abstract
Autophagy is a critical player in lumbar intervertebral disk degeneration (IDD), and autophagy activation has been suggested to prevent the apoptosis of nucleus pulposus cells (NPCs). Myricetin has anti-cancer, anti-inflammatory, and antioxidant potentials and can activate autophagy. Thus, this study focused on the roles and mechanisms of myricetin in IDD. A puncture-induced rat IDD model was established and intraperitoneally injected with 20-mg/kg/day myricetin. Histopathological changes of intervertebral disks (IVDs) were assessed by hematoxylin and eosin staining and Safranin O/Fast Green staining. The isolated NPCs from IVDs of healthy rats were stimulated with IL-1β to mimic IDD-like conditions. The roles of myricetin in cell apoptosis, extracellular matrix (ECM) degradation, autophagy repression, and the JAK2/STAT3 pathway activation were examined by cell counting kit-8, flow cytometry, western blotting, real-time quantitative polymerase chain reaction, and immunofluorescence staining. Myricetin treatment attenuated the apoptosis and ECM degradation, and enhanced autophagy in the IL-1β-treated NPCs, whereas the myricetin-mediated protection was limited by autophagy inhibition. Mechanistically, myricetin activated autophagy through blocking the JAK2/STAT3 signaling. In vivo experiments revealed that intraperitoneal injection of myricetin activated NPC autophagy to relieve puncture injury in rats. Myricetin prevents IDD by attenuating NPC apoptosis and ECM degradation through blocking the JAK2/STAT3 pathway to enhance autophagy.

Abstract
Intervertebral disk degeneration (IVDD) is the major cause of low back pain. Alpha-ketoglutaric acid (α-KG), an important intermediate in energy metabolism, has various functions, including epigenetic regulation, maintenance of redox homeostasis, and antiaging, but whether it can ameliorate IVDD has not been reported. Here, we examined the impacts of long-term administration of α-KG on aging-associated IVDD in adult rats. In vivo and in vitro experiments showed that α-KG supplementation effectively ameliorated IVDD in rats and the senescence of nucleus pulposus cells (NPCs). α-KG supplementation significantly attenuated senescence, apoptosis, and matrix metalloproteinase-13 (MMP-13) protein expression, and it increased the synthesis of aggrecan and collagen II in IL-1β-treated NPCs. In addition, α-KG supplementation reduced the levels of IL-6, phosphorylated JAK2 and STAT3, and the nuclear translocation of p-STAT3 in IL-1β-induced degenerating NPCs. The effects of α-KG were enhanced by AG490 in NPCs. The underlying mechanism may involve the inhibition of JAK2/STAT3 phosphorylation and the reduction of IL-6 expression. Our findings may help in the development of new therapeutic strategies for IVDD.NEW & NOTEWORTHY Alpha-ketoglutaric acid (α-KG) exerted its protective effect on nucleus pulposus cells' (NPCs) degeneration by inhibiting the senescence-associated secretory phenotype and extracellular matrix degradation. The possible mechanism may be associated with negatively regulating the JAK2/STAT3 phosphorylation and the decreased IL-6 expression, which could be explained by a blockage of the positive feedback control loop between IL-6 and JAK2/STAT3 pathway.

Abstract
Aims This study aimed, through bioinformatics analysis and in vitro experiment validation, to identify the key extracellular proteins of intervertebral disc degeneration (IDD). Methods The gene expression profile of GSE23130 was downloaded from the Gene Expression Omnibus (GEO) database. Extracellular protein-differentially expressed genes (EP-DEGs) were screened by protein annotation databases, and we used Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) to analyze the functions and pathways of EP-DEGs. STRING and Cytoscape were used to construct protein-protein interaction (PPI) networks and identify hub EP-DEGs. NetworkAnalyst was used to analyze transcription factors (TFs) and microRNAs (miRNAs) that regulate hub EP-DEGs. A search of the Drug Signatures Database (DSigDB) for hub EP-DEGs revealed multiple drug molecules and drug-target interactions. Results A total of 56 EP-DEGs were identified in the differential expression analysis. EP-DEGs were enriched in the extracellular structure organization, ageing, collagen-activated signalling pathway, PI3K-Akt signalling pathway, and AGE-RAGE signalling pathway. PPI network analysis showed that the top ten hub EP-DEGs are closely related to IDD. Correlation analysis also demonstrated a significant correlation between the ten hub EP-DEGs (p<0.05), which were selected to construct TF-gene interaction and TF-miRNA coregulatory networks. In addition, ten candidate drugs were screened for the treatment of IDD. Conclusion The findings clarify the roles of extracellular proteins in IDD and highlight their potential as promising novel therapeutic targets.

Abstract
CONTEXT Cyanidin has been shown to have therapeutic potential in osteoarthritis. However, it is unclear whether cyanidin prevents the progression of intervertebral disc degeneration (IVDD). OBJECTIVE This study evaluates the effects of cyanidin on IVDD in vitro and in vivo. MATERIALS AND METHODS Nucleus pulposus cells (NPCs) isolated from lumbar IVD of 4-week-old male Sprague-Dawley (SD) rats were exposed to 20 ng/mL IL-1β, and then treated with different doses (0-120 µM) of cyanidin for 24 h. SD rats were classified into three groups (n = 8) and treated as follows: control (normal saline), IVDD (vehicle), IVDD + cyanidin (50 mg/kg). Cyanidin was administered intraperitoneally for 8 weeks. RESULTS The IC50 of cyanidin for NPCs was 94.78 µM, and cyanidin had no toxicity at concentrations up to 500 mg/kg in SD rats. Cyanidin inhibited the apoptosis of NPCs induced by IL-1β (12.73 ± 0.61% vs. 18.54 ± 0.60%), promoted collagen II (0.82-fold) and aggrecan (0.81-fold) expression, while reducing MMP-13 (1.02-fold) and ADAMTS-5 (1.40-fold) expression. Cyanidin increased the formation of autophagosomes in IL-1β-induced NPCs, and promoted LC3II/LC3I (0.83-fold) and beclin-1 (0.85-fold) expression, which could be reversed by chloroquine. Cyanidin inhibited the phosphorylation of JAK2 (0.47-fold) and STAT3 (0.53-fold) in IL-1β-induced NPCs. The effects of cyanidin could be enhanced by AG490. Furthermore, cyanidin mitigated disc degeneration in IVDD rats in vivo. DISCUSSION AND CONCLUSIONS Cyanidin improved the function of NPCs in IVDD by regulating the JAK2/STAT3 pathway, which may provide a novel alternative strategy for IVDD. The mechanism of cyanidin improving IVDD still needs further work for in-depth investigation.

Abstract
Buyang Huanwu decoction (BYHWD), as one of the traditional Chinese medicine formulas, is widely used in the clinical treatment of lumbar disc herniation (LDH) with curative effect. It has the characteristics of multi-component, multi-target, and mutual synergy, but the mechanism of action is often unclear. It needs some research to explore the molecular mechanism of BYHWD in the treatment of LDH based on network pharmacology and molecular docking. Screen the active compounds of BYHWD and predict drug-related gene/protein targets, which could determine the specific target of BYHWD in the treatment of LDH. Construct the "Drugs-Compounds-Targets" network and search for the core targets. Use Gene Ontology functional enrichment analysis, Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis, and molecular docking verification to explore the possible molecular mechanism. Eighty-two effective compounds and 666 targets of BYHWD, 187 targets for LDH treatment, and 20 core candidate targets were excavated. A total of 3414 entries were identified by Gene Ontology enrichment analysis, 173 related signal pathways were identified by Kyoto Encyclopedia of Genes and Genomes enrichment analysis, and 5 core compounds were identified by molecular docking, which had a good affinity with core genes STAT3, JUN, AKT1, MAPK1, RELA, and PIK3CA. BYHWD may play the role of analgesic and improving function by synergistic anti-inflammatory and analgesic compounds, regulating cell metabolic differentiation, regulating immunity, and anticoagulation. BYHWD in the treatment of LDH may play a role in analgesia and improve function through multiple signaling pathways, including PI3K-Akt, mitogen-activated protein kinase, tumor necrosis factor, and interleukin-17. The PI3K-Akt signaling may be one of the key mechanisms.

Abstract
Astragaloside IV (AS IV) and tanshinone (TS IIA) are the main natural components of Salvia miltiorrhiza and Radix Astragali, respectively. The amalgam of TS IIA and AS IV has potential therapeutic value in many inflammation-related diseases. However, the aftereffect of TS IIA and AS IV for lumbar disc herniation is not clear. Although the function of miR-223 in the inflammation-related JAK/STAT pathway is unknown, it is particularly expressed in human degenerative nucleus pulposus cells. This study has investigated the efficacy of the combined application of TS IIA and AS IV in the treatment of intervertebral disc nucleus pulposus cells (NP cells) injured by lipopolysaccharide (LPS). After miR-223 inhibitor imitated NP cells, the state of the JAK family and STAT family was recognized by Western blotting (Western blot, WB) and reverse transcriptase quantitative polymerase chain reaction (qPCR). The shRNA lentivirus interference vector targeting the STAT family was constructed, and the NP cell line stably interfering with the STAT gene was established after transfection. The expression of TNF-α, IL-6, MMP-9, MMP-3, caspase-1, and caspase-3 was detected by lipopolysaccharide (WTNP cells), control virus NP cells, STAT downregulation NP cells, enzyme-linked immunosorbent assay (ELISA), Western blot, and qPCR, respectively. The cell survival rate was detected by flow cytometry and TUNEL staining reverse transcriptase-polymerase chain reaction (qPCR). NP cells were treated with TS IIA and AS IV which had been made into different concentrations, and then, the expression of miR-223, p-STAT1, and p-JAK families was detected by WB Western blotting and qPCR. MiR-223 selectively acts on JAK2/STAT1 pathway, increases the expression of TNF-α, IL-6, MMP-9, MMP-3, caspase3-1, and caspase-3, and induces apoptosis, which can be eliminated by silencing STAT1. TS IIA combined with AS IV could inhibit the expression of miR-223, p-STAT1, and p-JAK2 in NP cells, and they showed a dose-dependent tendency to p-STAT1 and p-JAK2. This study shows that miR-223 promotes the inflammatory response and induces cell injury of NP cells by acting on the JAK2/STAT1 pathway, and the combination of TS IIA and AS IV may protect NP cells by downregulating miR-223 and inhibiting the expression of JAK2 and STAT1.

Abstract
In this study, we attempted to further collate existing transcriptome sequencing (mRNA-Seq) data by applying data mining and screening intervertebral disc degeneration (IVDD)-related miRNAs. At the same time, combined with published articles, the miRNAs that have been screened out were further excluded, and only the miRNAs confirmed by the reported studies were retained and reviewed. We obtained 12 pro-IVDD miRNAs and ten anti-IVDD miRNAs using the above screening process, involving 33 literature sources. By reviewing and summarizing the above studies, we preliminarily constructed the regulatory network of miRNA in the pathogenesis of IVDD. This regulatory network comprises many gaps and potential miRNA interactions, and these points may be the breakthrough points for further IVDD-related research. This new review approach can also provide a reference for the mechanistic studies of other diseases.

Abstract
The incidence of lower back pain caused by intervertebral disc degeneration (IDD) is gradually increasing. IDD not only affects the quality of life of the patients, but also poses a major socioeconomic burden. There is currently no optimal method for delaying or reversing IDD, mainly due to its unknown pathogenesis. MicroRNAs (miRNAs/miRs) participate in the development of a number of diseases, including IDD. Abnormal expression of miRNAs in the intervertebral disc is implicated in various pathological processes underlying the development of IDD, including nucleus pulposus (NP) cell (NPC) proliferation, NPC apoptosis, extracellular matrix remodeling, inflammation and cartilaginous endplate changes, among others. The focus of the present review was the advances in research on the involvement of miRNAs in the mechanism underlying IDD. Further research is expected to identify markers for early diagnosis of IDD and new targets for delaying or reversing IDD.

Abstract
Objectives: Anisodamine (ANI) has been used to treat a variety of diseases. However, the study of ANI in intervertebral disc degeneration (IVDD) is unclear. This study investigated the effects of ANI on degenerative nucleus pulposus cells (NPCs) and IVDD rats, and its possible mechanisms. Methods: Human nucleus pulposus cells (HNPCs) were treated with IL-1β (20 ng/ml) to simulate IVDD, and an IVDD rat model was constructed. IL-1β-induced HNPCs were treated with different concentrations (10, 20, or 40 μM) of ANI, and IVDD rats were also treated with ANI (1 mg/kg). Results: ANI treatment significantly reduced the apoptosis, caspase-3 and SA-β-gal activities, and p53 and p21 proteins expression, while promoted telomerase activity and aggrecan and collagen II synthesis in IL-1β-induced HNPCs. Moreover, the introduction of ANI inhibited the expression of IL-6, phosphorylation of JAK and STAT3, and nuclear translocation of p-STAT3 in Degenerated HNPCs. Additionally, the application of ANI abolished the effects of IL-6 on apoptosis, SA-β-gal and telomerase activity, and the expression of p53, p21, aggrecan and collagen II proteins in degenerated HNPCs. Simultaneously, ANI treatment enhanced the effects of AG490 (inhibitor of JAK/STAT3 pathway) on IL-1β-induced apoptosis, senescence and ECM degradation in HNPCs. Furthermore, ANI treatment markedly inhibited the apoptosis and senescence in the nucleus pulposus of IVDD rats, while promoted the synthesis of aggrecan and collagen II. ANI treatment obviously inhibited JAK and STAT3 phosphorylation and inhibited nuclear translocation of p-STAT3 in IVDD rats. Conclusion: ANI inhibited the senescence and ECM degradation of NPCs by regulating the IL-6/JAK/STAT3 pathway to improve the function of NPCs in IVDD, which may provide new ideas for the treatment of IVDD.

Objectives The aim of our study was to ascertain the underlying role of microRNAs (miRNAs) in human intervertebral disc degeneration (IDD). Design Bioinformatic analysis from multiple databases. Methods Studies of the association of miRNAs and IDD were identified in multiple electronic databases. All potential studies were assessed by the same inclusion and exclusion criteria. We recorded whether miRNA expression was commonly increased or suppressed in the intervertebral disc tissues and cells of IDD subjects. We used String to identify biological process and cellular component pathways of differentially expressed genes. Results We included fifty-seven articles from 1,277 records in this study. This report identified 40 different dysregulated miRNAs in 53 studies, including studies examining cell apoptosis (26 studies, 49.06%), cell proliferation (15 studies, 28.3%), extracellular matrix (ECM) degradation (10 studies, 18.86%), and inflammation (five studies, 9.43%) in IDD patients. Three upregulated miRNAs (miR-19b, miR-32, miR-130b) and three downregulated miRNAs (miR-31, miR-124a, miR-127-5p) were considered common miRNAs in IDD tissues. The top three biological process pathways for upregulated miRNAs were positive regulation of biological process, nervous system development, and negative regulation of biological process, and the top three biological process pathways for downregulated miRNAs were negative regulation of gene expression, intracellular signal transduction, and negative regulation of biological process. Conclusions This study revealed that miRNAs could be novel targets for preventing IDD and treating patients with IDD by regulating their target genes. These results provide valuable information for medical professionals, IDD patients, and health care policy makers.

Abstract
Matrix metalloproteinases (MMPs) are required for collagen degradation which play a key pathological role in arthritis progression. Herein, the effect of sinomenine (SN) on Interleukin 1 beta (IL-1β)-induced MMPs production and its underlying mechanism were explored in SW1353 cells. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay showed that 200 and 400 µM SN significantly inhibited SW1353 cell proliferation, thus the lower dose of SN (25-100 µM) were used in the subsequent experiments. Notably, the increased mRNA and protein levels of suppressor of cytokine signaling (SOCS) 3 were dose-dependently induced by SN. SN significantly suppressed mRNA and protein levels of MMPs in IL-1β-induced SW1353 cells. Through Western blot analysis, SN showed inhibitory effect on IL-1β-induced TAK1 and p65 phosphorylation. Moreover, SN blocked the interaction of TRAF6 and TAK1 resulting in inactivation of IL-1β pathway. Mechanistically, the inhibitory effect of SN on MMPs levels alongside TRAF6 and TAK1 interactions was abrogated by silencing SOCS3. Moreover, SN did not inhibit TAK1 kinase activity. In TAK1 silencing cells, the levels of MMPs and p65 phosphorylation of SN-treatedcells were lower than dimethyl sulfoxide (DMSO)-treated cells, indicating that blocking interaction was not a unique way for SN to inhibit MMPs levels. Finally, SN significantly inhibited IL-6-induced Janus tyrosine kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3) phosphorylation in SW1353 cells. The levels of JAK2 phosphorylation and MMPs did not show a significant difference between IL-6 + SOCS3-small interfering RNA (siRNA) + SN group and IL-6 + SOCS3-siRNA + DMSO group. These findings demonstrated that SOCS3 expression was increased by SN blocked IL-1β-induced interaction between TRAF6 and TAK1 as well as IL-6 pathway activation, thereby culminating in the inhibition of MMPs levels.

Abstract
Accumulating evidence demonstrates that estrogen receptor α (ERα) and microRNAs (miRNAs) play crucial roles in intervertebral disc degeneration (IDD). However, the specific miRNA that related with ERα during IDD development remains unknown. Therefore, we aimed to explore the role of ERα-related miRNA in the IDD model. Nucleus pulposus (NP) cells were isolated from IDD patients. ERα-related miRNAs were selected and verified in NP tissues from IDD patients using quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Also, the related cytokine mRNA levels were detected by qRT-PCR. Protein levels were determined by Western blot. The concentrations of inflammatory cytokines in culture supernatants were detected by enzyme-linked immunosorbent assay. MiR-203-3p was found to be upregulated in NP tissues of high-grade IDD patients compared with low-grade IDD patients, and negatively associated with ERα expression. MiR-203-3p directly targeted ERα in NP cells of IDD patients. After lipopolysaccharides (LPS) stimulation, miR-203-3p expression increased, while ERα expression decreased in NP cells. MiR-203-3p inhibition suppressed the effect of LPS on ERα expression and IDD related genes, while ERα downregulation rescued the effect of LPS. In conclusion, suppression the expression of miR-203-3p could inhibit LPS-induced human intervertebral disc inflammation and degeneration through upregulating ERα.

Abstract
Dysfunction of cartilaginous endplates (CEP) is an important etiologic aspect of intervertebral disc degeneration (IDD) because the endplate has nutritional and biomechanical functions in maintaining proper disc health. In this study, we investigated the regulatory effects of estrogen on degenerated human CEP cells and the involvement of miR-221 in these effects. Normal and degenerated human CEP tissues were collected from patients with idiopathic scoliosis and IDD, respectively. CEP cells were isolated from these tissues. Polymerase chain reaction (PCR) and western blot analysis were performed to detect the expression of specific genes and proteins, respectively. Apoptosis and cell cycle were analyzed by flow cytometry. The results showed that the levels of aggrecan, collagen II, TGF-β and estrogen receptor α (ERα) were decreased in degenerated CEP tissues, while the levels of MMP-3, adamts-5, IL-1β, TNF-α, IL-6, and miR-221 were increased. Treatment of degenerated CEP cells with 17beta-estradiol (E2) increased the expressions of aggrecan and collagen II, as well as the secretion of TGF-β, but decreased IL-6 secretion. Moreover, E2 inhibited the apoptosis, resumed cell-cycle progression in G0/G1 phase, and improved the cell viability. These data indicate that estrogen has protective effect against degeneration of CEP cells. Furthermore, ERα was confirmed to be a target of miR-221 by the luciferase assay. The synthetic miR-221 mimics or knockdown of ERα attenuated the protective effects of E2, but miR-221 inhibitors promoted the protective effects of E2. These results suggest that miR-221 may impair the protective effect of estrogen in degenerated CEP cells through targeting ERα. This study reveals an important mechanism underlying the degeneration of CEP cells.
