BACKGROUND AND AIMS: Thrombomodulin (TM), through its lectin-like domain (TMD1), sequesters proinflammatory high-mobility group box 1 (HMGB1) to prevent it from engaging the receptor for advanced glycation end product (RAGE) that sustains inflammation and tissue damage. Our previous study demonstrated that short-term treatment with recombinant TM containing all the extracellular domains (i.e., rTMD123) inhibits HMGB1-RAGE signaling and confers protection against CaCl2-induced AAA formation...

Approximately 30% of epilepsy patients do not respond to antiepileptic drugs, representing an unmet medical need. There is evidence that neuroinflammation plays a pathogenic role in drug-resistant epilepsy. The high-mobility group box 1 (HMGB1)/TLR4 axis is a key initiator of neuroinflammation following epileptogenic injuries, and its activation contributes to seizure generation in animal models. However, further work is required to understand the role of HMGB1 and its isoforms in epileptogenesis and drug resistance...

Clofibrate is a known rodent hepatotoxicant classically associated with hepatocellular hypertrophy and increased serum activities of cellular alanine aminotransferase/aspartate aminotransferase (ALT/AST) in the absence of microscopic hepatocellular degeneration. At toxic dose, clofibrate induces liver and skeletal muscle injury. The objective of this study was to assess novel liver and skeletal muscle biomarkers following clofibrate administration in Wistar rats at different dose levels for 7 days. In addition to classical biomarkers, liver injury was assessed by cytokeratin 18 (CK18) cleaved form, high-mobility group box 1, arginase 1 (ARG1), microRNA 122 (miR-122), and glutamate dehydrogenase...

High mobility group box 1 (HMGB1) is abundantly expressed in intracellular engaged DNA binding ability. However, more importantly, it is a weapon against infection through proinflammatory response and immune regulation while released to extracellular. Toxoplasma gondii causes inflammatory pathological changes including ileitis and encephalitis in chronic infection. To investigate whether HMGB1 contributes to the toxoplasmosis lesions, we examined HMGB1 changes during T. gondii infection. The results showed that HMGB1 transcription was down-regulated in the murine macrophage ANA1 cell line and mouse peritoneal macrophages (PMΦs) after T...

Plasma endothelial cell-derived exosomes (EDEs) and platelet-derived exosomes (PDEs) were precipitated and enriched separately by immunospecific absorption procedures for analyses of cargo proteins relevant to atherosclerosis. EDEs had usual exosome size and marker protein content, and significantly higher levels than PDEs of the endothelial proteins vascular cell adhesion molecule-1 (VCAM-1) and endothelial nitric oxide synthase, whereas PDEs had significantly higher levels of platelet glycoprotein VI. EDE levels of VCAM-1, von Willebrand factor, platelet-derived growth factor (PDGF)-BB, angiopoietin-1, and lysyl oxidase-2 and the cerebrovascular-selective proteins glucose transporter 1, permeability-glycoprotein, and large neutral amino acid transporter 1 were significantly higher for 18 patients with cerebrovascular disease (CeVD) than for 18 age- and gender-matched control subjects...

Osteoarthritis (OA) is a chronic disease that degrades the joints and is often associated with increasing age and obesity. The two most common sites of OA in adults are the knee and hip joints. Increased mechanical stress on the joint from obesity can cause the articular cartilage to degrade and release damage-associated molecular patterns (DAMPs). These DAMPs are involved in various molecular pathways that interact with nuclear factor-kappa B and result in the transcription of inflammatory cytokines and activation of matrix metalloproteinases that progressively destroy cartilage...

Pediatric high-grade gliomas represent 8-12% of all primary tumors of the nervous system in children. Five-year survival for these pediatric aggressive tumors is poor (15-35%) indicating the need to develop better treatments for pediatric high-grade gliomas. In this work we used SF188 and SJ-GBM2 cell lines to study the function of the ubiquitin carboxyl-terminal esterase L1 (UCHL1), a deubiquitinase de-regulated in several cancers, in pediatric high-grade gliomas. UCHL1 depletion in SF188 and SJ-GBM2 glioma cells was associated with decreased cell proliferation and invasion, along with a reduced ability to grow in soft agar and to form spheres (i...

Melatonin (N-acetyl-5-methoxytryptamine), a circadian-regulating hormone, has been reported to exert a protective role during acute kidney injury (AKI) induced by renal ischemia-reperfusion injury (I/R). High-mobility group box 1 (HMGB1) is a novel member of the damage-associated molecular pattern (DAMP) family, and has been verified to be an inflammatory cytokine mediating AKI induced by I/R and cisplatin. However, the effect of melatonin on HMGB1, as well as the relationship of these two with folic acid induced AKI are elusive...

SOX4 (sex-determining region Y-related high-mobility group box 4) is associated with tumor progression and poor clinical outcome in several cancers. This study aims to evaluate whether SOX4 affects the biological behaviors of prostate cancer and further elucidate whether this effect works through the epithelial-mesenchymal transition pathway. We investigated the expression of SOX4 in a series of prostate cancer tissues and adjacent noncancerous tissues, as well as in a panel of prostate cancer cell lines. Cell proliferation, migration, and invasion were evaluated in SOX4 knockdown prostate cancer cell lines by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and Transwell assay...

BACKGROUND: Sirtuin 1 (SIRT1) is a nicotinamide adenine dinucleotide +-dependent histone deacetylase that regulates various pathways involved in ischemia-reperfusion injury (IRI). Moreover, high-mobility group box 1 protein (HMGB1) has also been involved in inflammatory processes during IRI. However, the roles of both SIRT1 and HMGB1 in liver preservation is poorly understood. In this communication, we evaluated the potential relationship between SIRT1 and HMGB1 in steatotic and non-steatotic liver grafts preserved in Institute Georges Lopez solution (IGL-1) preservation solution enriched or not enriched with trimetazidine (TMZ)...

Inflammatory processes in brain tissue have been described in human epilepsy of various etiologies and in experimental models of seizures. High mobility group box-1 (HMGB1) is now recognized as representative of damage-associated molecular patterns (DAMPs). In the present study, we focused on whether anti-HMGB1 antibody treatment could relieve status epilepticus- triggered BBB breakdown and inflammation response in addition to the seizure behavior itself. Pilocarpine and methyl-scopolamine were used to establish the acute seizure model...

miR-142-3p was reported to be downregulated in acute myelogenous leukemia (AML) and acted as a novel diagnostic marker. However, the regulatory effect of miR-142-3p on drug resistance of AML cells and its underlying mechanism have not been elucidated. Here, we found that miR-142-3p was significantly downregulated and high mobility group box 1 (HMGB1) was dramatically upregulated in AML samples and cells, as well as drug-resistant AML cells. P-gp level and autophagy were markedly enhanced in HL-60/ADR and HL-60/ATRA cells...

Hand, foot, and mouth disease (HFMD) is a common pediatric disease caused by enterovirus infection. It typically presents as a fever along with flat, discolored spots and bumps on the hands, feet, and mouth. Compared with other viruses, enterovirus 71 (EV71)-induced HFMD is more prone to cause severe complications in children, such as brainstem encephalitis, cardiopulmonary disorders, and even death. More in-depth studies are still necessary to understand the characteristics of EV71-induced HFMD, although some related research has been reported so far...

It is now apparent that antigen-specific T-cells are activated in certain patients with drug-induced liver injury (DILI). Since cross-talk between hepatocytes and immune cells is likely to be critical in determining the outcome of drug exposure, the aim of this study was to profile the signals released by drug-treated hepatocytes and to characterise the impact of these molecules on dendritic cells. Human hepatocytes were exposed to three drugs (flucloxacillin, amoxicillin and isoniazid) associated with DILI potentially mediated by the adaptive immune system as drug-specific T-cells have been isolated from DILI patients, and the metabolite nitroso-sulfamethoxazole (SMX-NO)...
