Abstract
OBJECTIVE To analyze available literature data on the role of genetic factors in degenerative disc disease. METHODOLOGY We reviewed the PubMed, MEDLINE, Cohrane Library, e-Library databases using the following keywords: degenerative spine lesions, intervertebral disc herniation, pathogenesis, genetic regulation. RESULTS Searching depth was 2002-2022. We reviewed 84 references. Exclusion criteria: duplicate publications, reviews without detailed description of results, opinions. Finally, we included 43 the most significant studies. CONCLUSION There are literature data on proinflammatory cytokines, growth factors and osteodestructive processes in pathogenesis of degenerative disc disease. However, there is only fragmentary information about the role of genetic regulation of these processes. Some factors, such as microRNA, TGF-b, VEGF, MMP are still poorly understood.

Abstract
PURPOSE Tuberculosis is one of the oldest diseases in human history, and spinal tuberculosis (STB) is the most common form of extrapulmonary tuberculosis. A large number of research has been conducted in this field. However, there has been no bibliometric analysis performed in recent years in STB. The aim of this study was to analyze trends and hotspots in research on STB. METHODS Publications regarding STB between 1980 and 2022 were extracted from the Web of Science database. CiteSpace (V5.7.R2) and VOSviewer (1.6.10) were used to perform global analyses of the number of publications, countries, institutions, authors, journals, keywords, and cited references. RESULTS A total of 1262 articles were published between 1980 and 2022. We observed rapid growth in the number of publications since 2010. Spine had the highest number of publications (47, 3.7%). Zhang HQ and Wang XY were key researchers. The Central South University published the most papers (90, 7.1%). China was the leading contributor in this field with 459 publications and 29 H-index. National partnerships are dominated by the USA, and there is a lack of active cooperation between other countries and authors. CONCLUSION research on STB has achieved great progress, with an increasing number of publications since 2010. Surgical treatment and debridement are current research hots pots, and diagnosis, drug resistance, and kyphosis are likely research frontiers. Cooperation between countries and authors needs to be further strengthened.

Abstract
Tuberculosis (TB), one of the top ten causes of death globally induced by the infection of Mycobacterium tuberculosis (Mtb), remains a grave public health issue worldwide. With almost one-third of the world's population getting infected by Mtb, between 5% and 10% of these infected individuals are predicted to develop active TB disease, which would not only result in severe tissue damage and necrosis, but also pose serious threats to human life. However, the exact molecular mechanisms underlying the pathogenesis and immunology of TB remain unclear, which significantly restricts the effective control of TB epidemics. Despite significant advances in current detection technologies and treatments for TB, there are still no appropriate solutions that are suitable for simultaneous, early, rapid, and accurate screening of TB. Various cellular events can perturb the development and progression of TB, which are always associated with several specific molecular signaling events controlled by dysregulated gene expression patterns. Long non-coding RNAs (lncRNAs), a kind of non-coding RNA (ncRNA) with a transcript of more than 200 nucleotides in length in eukaryotic cells, have been found to regulate the expression of protein-coding genes that are involved in some critical signaling events, such as inflammatory, pathological, and immunological responses. Increasing evidence has claimed that lncRNAs might directly influence the susceptibility to TB, as well as the development and progression of TB. Therefore, lncRNAs have been widely expected to serve as promising molecular biomarkers and therapeutic targets for TB. In this review, we summarized the functions of lncRNAs and their regulatory roles in the development and progression of TB. More importantly, we widely discussed the potential of lncRNAs to act as TB biomarkers, which would offer new possibilities in novel diagnostic strategy exploration and benefit the control of the TB epidemic.

Abstract
Spinal tuberculosis, also known as Pott's disease or tuberculous spondylitis, is usually secondary to primary infection in the lungs or other systems, and in most instances, is thought to be transmitted via blood. Typical manifestations of infection include narrowing of the intervertebral disc by erosion and bone destruction of adjacent vertebrae. Atypical spinal tuberculosis is a specific type of spinal tuberculosis. It mainly consists of single vertebral lesions, single posterior structure lesions, multiple vertebral lesions, and intra-spinal lesions. Skipped multifocal spinal tuberculosis is one of these types and is characterized by two or more vertebral lesions without the involvement of the adjoining intervertebral discs, regardless of their location. To date, only a few cases have been reported. Upon clinical admission, it can be treated conservatively or surgically, depending on the patient's symptoms. In addition, gene or biological therapies are being investigated. However, because of the exceptional imaging findings and insidious symptoms, it is often misdiagnosed as a neoplastic lesion, osteoporotic fracture, or other infectious spondylitis, increasing the risk of neurological deficit and kyphotic deformity, and delaying the optimal treatment window. In this study, we review the diagnosis and treatment strategies for skipped multifocal spinal tuberculosis lesions and enumerate the common differential diagnoses, to provide reference and guidance for clinical treatment and diagnosis direction.

Vitamin D receptor activated by vitamin D administration alleviates Mycobacterium tuberculosis-induced bone destruction by inhibiting NFκB-mediated aberrant osteoclastogenesis.

Abstract
Clinically, bone destruction caused by Mycobacterium tuberculosis was serious especially in patients with vitamin D (VD) deficiency. However, the role of VD in M. tuberculosis-induced bone destruction remains clear. In this context, we investigate the role of VD and vitamin D receptor (VDR) in the M. tuberculosis-induced bone destruction. First, we infected RAW264.7 and bone marrow-derived macrophages (BMMs) with Mycobacterium bovis Bacillus Calmette-Guérin (M. bovis BCG) in vitro. Then, we activated VDR through VD administration. TRAP and FAK staining, bone resorption assays, immunofluorescence staining, qPCR, and western blot were carried out. In vivo, the M. tuberculosis-induced osteolytic model on the murine skull was established and the μCT and histological analyses were performed. We found that VDR and TRAP were upregulated in bone tuberculosis tissue and proved that M. tuberculosis infection promoted osteoclastogenesis in RAW264.7 and BMMs. VD could inhibit osteoclasts differentiation, fusion, and bone resorption dose-dependently. However, when VDR was knocked down, the inhibitory effect of VD on osteoclasts disappeared. In mechanism, activation of VDR inhibits the phosphorylation of IκB α, thereby inhibiting NFκB signaling pathway and alleviating osteoclastogenesis. Furthermore, in the skull osteolysis model, VD administration reduced osteolysis, but not in VDR-/- mice. Our study, for the first time, demonstrates that activation of VDR by VD administration inhibits M. tuberculosis-induced bone destruction. Our results reveal that VD and VDR are potential therapeutic targets for M. tuberculosis-induced bone destruction, and are of great clinical significance for the development of new therapeutic strategies.

Abstract
Matrix Metalloproteinases (MMPs), as a family of zinc-containing enzymes, show the function of decomposing Extracellular Matrix (ECM) and participate in the physiological processes of cell migration, growth, inflammation, and metabolism. Clinical and experimental studies have indicated that MMPs play an essential role in tissue injury and repair as well as tumor diagnosis, metastasis, and prognosis. An increasing number of researchers have paid attention to their functions and mechanisms in bone health and diseases. The present review focuses on MMPs-inspired therapeutic strategies for the treatment of bone-related diseases. We introduce the role of MMPs in bone diseases, highlight the MMPs-inspired therapeutic options, and posit MMPs as a trigger for smart cell/drug delivery.

Abstract
The specific cytotoxic effects of nanoparticles on tumor cells may be used in future antitumor clinical applications. Gold nanoparticles (AuNPs) have been reported to produce potent cytotoxic effects; however, the precise mechanism is unclear. In this study, AuNPs were synthesized; the average size of the particles was 62.2 ± 6 nm with smooth surface and multiple shapes, which were determined using transmission electron microscopy and field emission scanning electron microscopy. The selected area electron diffraction patterns suggested that the synthesized AuNPs were crystalline. The X-ray photoelectron spectroscopy (XPS) spectrum of the synthesized AuNPs has presented an intense peak at 100 eV, signifying the entire composition of Au in the developed AuNPs. This synthesized AuNPs showed the most potent efficacy in prostate cancer cells, regardless of whether or not they were androgen dependent. Secretome determinations using two-dimensional difference in-gel electrophoresis (2D-DIGE), followed by enzyme-linked immunosorbent assay and quantitative reverse transcriptase-polymerase chain reaction validations, have identified a series of secretory proteins that were dysregulated by AuNP treatment in prostate cancer cells, many of which are highly involved in cytokine-chemokine functions, including CXCL3, interleukin-10, CCL2, and matrix metalloproteinase 9 (MMP9). Further research on molecular mechanism has indicated that AuNPs can trigger the secretion of anticancer factors and myeloid cell-polarizing factors from tumor cells through MMP9 inhibition. These results have clearly signified the cytotoxic potential of AuNPs for treating prostate cancer and may provide a novel direction for prostate cancer therapy in the future.

Abstract
As the most important bone-resorbing cells, osteoclasts play fundamental roles in bone remodeling and skeletal health. Much effort has been focused on identifying the regulators of osteoclast metabolism. Noncoding RNAs (ncRNAs) reportedly regulate osteoclast formation, differentiation, survival, and bone-resorbing activity to participate in bone physiology and pathology. The present review intends to provide a general framework for how ncRNAs and their targets regulate osteoclast differentiation and the important events of osteoclastogenesis they are involved in, including osteoclast precursor generation, early differentiation, mononuclear osteoclast fusion, and multinucleated osteoclast function and survival. This framework is beneficial for understanding bone biology and for identifying the potential biomarkers or therapeutic targets of bone diseases. The review also summarizes the results of in vivo experiments and classic experiment methods for osteoclast-related researches.

Abstract
Intervertebral disc (IVD) degeneration is a multifactorial pathological process associated with low back pain, the leading cause of years lived in disability worldwide. Key characteristics of the pathological changes connected with degenerative disc disease (DDD) are the degradation of the extracellular matrix (ECM), apoptosis and senescence, as well as inflammation. The impact of nonphysiological mechanical stresses on IVD degeneration and inflammation, the mechanisms of mechanotransduction, and the role of mechanosensitive miRNAs are of increasing interest. As post-transcriptional regulators, miRNAs are known to affect the expression of 30% of proteincoding genes and numerous intracellular processes. The dysregulation of miRNAs is therefore associated with various pathologies, including degenerative diseases such as DDD. This review aims to give an overview of the current status of miRNA research in degenerative disc pathology, with a special focus on the involvement of miRNAs in ECM degradation, apoptosis, and inflammation, as well as mechanobiology.

Abstract
Aim: PIWI-interacting RNAs (piRNAs) play crucial roles in germline development and carcinogenesis. The expression patterns of piRNAs in pulmonary tuberculosis (PTB) are still unclear. Materials & methods: Small RNA sequencing was applied to investigate peripheral blood piRNA expression patterns in PTB patients and healthy individuals. Results: A total of 428 upregulated and 349 downregulated piRNAs were identified from PTB patients. Target genes of dysregulated piRNAs were mainly involved in transcription and protein binding. Dysregulated piRNAs were enriched in many pathways related with immunity. Many target genes were regulated by the same piRNAs. Nucleotide bias of these piRNAs showed that piRNAs in peripheral blood may be formed from the primary biogenesis pathway. Conclusion: Findings demonstrated that the PIWI-piRNA pathway is active in human peripheral blood, where it may represent a new player in the PTB pathogenesis.

Abstract
The current study aimed to investigate microRNA-155 (miR-155) expression in spinal tuberculosis-induced intervertebral disc destruction and its regulatory role in disease pathogenesis. A total of 26 patients with intervertebral disc destruction induced by spinal tuberculosis and 31 healthy individuals were included. Reverse transcription-quantitative polymerase chain reactions, western blot analysis and ELISA were performed to detect mRNA and protein expression levels. A bioinformatics analysis was applied to predict the upstream regulator of matrix metalloproteinase (MMP)13, which was confirmed by dual-luciferase reporter assay. Compared with the control group, mRNA and protein expression levels of MMP13 were significantly increased in the intervertebral disc of patients with spinal tuberculosis. However, miR-155 expression in the intervertebral disc of patients with spinal tuberculosis was significantly decreased compared with the control group. Dual-luciferase reporter assays suggested that miR-155 bound to the 3′-untranslated region of MMP13 to regulate gene expression. In primary annulus fibrosus cells, upregulated miR-155 expression significantly decreased MMP13 expression in the cells and culture supernatant, whereas it increased type II collagen expression. Upregulated MMP13 expression in the intervertebral disc in patients with spinal tuberculosis may be correlated with downregulated miR-155 expression. miR-155 may regulate expression levels of associated proteins in the intervertebral disc via modulating MMP13 expression, which contributes to the disease pathogenesis. The results of the current study may provide the theoretical basis for the diagnosis and treatment of disc damages caused by spinal tuberculosis.

Effect of High Glucose on Human Alveolar Macrophage Phenotype and Phagocytosis of Mycobacteria. Lung 2018; 197:89-94. [PMID: 30474709 DOI: 10.1007/s00408-018-0181-z] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2018] [Accepted: 11/19/2018] [Indexed: 10/27/2022]
Abstract
PURPOSE Diabetes mellitus (DBM) reduces immunological activity and increases susceptibility to various infections, including tuberculosis (TB). Human alveolar macrophage (hAM) functions are altered in DBM. METHODS To mimic hyperglycemic conditions in the lung alveolus, we co-cultured a hAM cell line (Daisy cell line) with human umbilical vein endothelial cells for 48 h in the presence of culture media alone, normal glucose (5 mM), and high glucose (22 mM). Using flow cytometry, immunophenotype characterization included cell surface markers CD 11c, CD14, CD16, CD86, CD163, CD169, CD206, CX3CR-1, CSF-1R, and matrix metalloproteinase-9 (MMP9). Phagocytic function was measured by immunofluorescence microscopy at 24 h after inoculation of cells with GFP-expressing Mycobacterium smegmatis. RESULTS Direct exposure of AMs to high glucose and exposure in the co-culture system yield different results for the same phenotypic markers. MMP9 expression was increased under both conditions. CD169 and CX3CR1 expressions were decreased when AMs were exposed directly to high glucose but increased under co-culture. Immunofluorescence assay revealed that phagocytosis decreased in AMs when directly exposed to increased glucose levels from 2.5 mM to normal glucose (5 mM), yet AMs under co-culture did not show decreased phagocytosis until concentrations were raised to 25 mM. CONCLUSION Alteration in the expression of certain receptors may contribute to defective sentinel function of AMs, promoting susceptibility to TB in a diabetic host. Variability in cell surface marker expression under direct glucose exposure compared to exposure via co-culture reveals that cell signaling between endothelial cells and AMs may play a crucial role in the phenotypic expression of AMs.

Transcription factor 7-like 2 controls matrix degradation through nuclear factor κB signaling and is repressed by microRNA-155 in nucleus pulposus cells. Biomed Pharmacother 2018; 108:646-655. [PMID: 30245464 DOI: 10.1016/j.biopha.2018.09.076] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2018] [Revised: 09/04/2018] [Accepted: 09/12/2018] [Indexed: 12/13/2022] Open
Abstract
AIM TCF7L2, a key transcription factor in the canonical Wnt pathway, plays a vital role in the matrix degradation of chondrocytes. However, it is unknown whether TCF7L2 is important in the matrix metabolism of inner gel-like nucleus pulposus (NP) cells; thus, the aim of this study was to explore the effect and mechanism of TCF7L2 in this process. METHODS Western blotting and immunofluorescence analyses were used to observe TCF7L2 expression in rat and human NP tissues. Real-time PCR and western blotting were performed to detect the expression of TCF7L2 stimulated by inflammatory cytokines. Dual luciferase reporter assay, real-time PCR, western blotting and knockdown experiments were performed to demonstrate the role of NF-κB signaling in matrix regulation by TCF7L2 and the regulation of TCF7L2 by miR-155 in intervertebral disc degeneration. KEY FINDINGS TCF7L2 is present in rat and human NP tissues and is expressed in the nucleus of NP cells. TCF7L2 is refractory to stimulation of rat and human NP cells with the inflammatory cytokines TNF-α and IL-1β, in contrast to the results in other cell types. Loss-of-function experiments using TCF7L2 siRNA or lentiviral shTCF7L2 showed that TCF7L2 knockdown suppresses matrix degradation through p65/NF-κB signaling in the absence and presence of TNF-α. In addition, TCF7L2 expression is repressed by miR-155 overexpression and promoted by miR-155 inhibition. SIGNIFICANCE Overall, these results demonstrate that the suppression of TCF7L2, which is modulated by miR-155, inhibits matrix degradation through p65/NF-κB signaling. TCF7L2 suppression may have therapeutic potential in intervertebral disc degeneration.

Abstract
Tuberculosis (TB) is one of the most fatal infectious diseases, affecting one third of the world's population. The causative agent, Mycobacterium tuberculosis (Mtb), has a well-established ability to circumvent the host's immune system for its long-term intracellular survival. MicroRNAs (miRNAs) are crucial post-transcriptional regulators of immune response. They act by negatively regulating the expression levels of important genes in both innate and adaptive immunity. It has been established in recent studies that the host immune response against Mtb is regulated by many miRNAs, most of which are induced by Mtb infection. Moreover, differential expression of miRNA in tuberculosis (TB) patients may help distinguish between TB patients and healthy individuals or latent TB. In this review, we present the recent advancements on the miRNA regulation of the host responses against Mtb infection, as well as the potential of miRNAs to as biomarkers for TB diagnosis.
