Introduction: Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers in the world. Extra- and intra-cellular high-mobility motor box 1 (HMGB1) proteins are invovled in the pathogenesis and prognosis of cancer. Regarding this, the present study was conducted with the aim of investigating the expression of HMGB1 protein and mRNA levels in the blood, tumor tissue, and mar...

High‑mobility‑group‑box chromosomal protein 1 (HMGB1) is a ubiquitous and abundant nuclear protein in eukaryotic cells. Nuclear HMGB1 serves an important role in maintaining nuclear stability under stress. However, extracellular HMGB1 exerts actions, which are distinctly different compared with these intracellular functions. HMGB1, when released extracellularly, is a potent innate signal, which...

High-mobility group protein 1 (HMGB1) is an essential and ubiquitous DNA architectural factor that influences a myriad of cellular processes. HMGB1 contains two DNA-binding domains, box A and box B, which have little sequence specificity but have remarkable abilities to underwind and bend DNA. Although HMGB1 box A is thought to be responsible for the majority of HMGB1-DNA interactions with pre-...

BACKGROUND Ethyl pyruvate (EP) has been reported to offer a protective effect against ischemic injury through its antiinflammatory action. The nuclear protein high-mobility group box 1 (HMGB1) can activate inflammatory pathways when released from ischemic cells. This study was designed to investigate the neuroprotective effect of EP against spinal cord ischemic injury and the potential role of ...

We studied the level of high mobility group box 1(HMGB1) in preterm infants with intraventricular hemorrhage (IVH). Using enzyme-linked immunosorbent assay (ELISA), the concentration of HMGB1 in cord blood obtained from 41 infants with IVH and 67 infants without IVH were measured. The cord blood concentration of HMGB1 in infants with IVH were significantly higher than those without IVH (P=0.041...

objective: nutrients and antioxidants in the medium of immature oocyte have a profound effect on maturation, fertilization and development of resulting embryos. in this study the effects of melatonin as an antioxidant agent on maturation, glutathione level and expression of high mobility group box-1 (hmgb1) gene were evaluated in immature oocytes of mice stained with brilliant cresyl blue (bcb)...

Spinal cord injury (SCI) causes motor and sensory deficits is currently considered an incurable disease. We have previously reported that administration of anti-High Mobility Group Box-1 monoclonal antibody (anti-HMGB1 mAb) preserved lesion area improved locomotion recovery in mouse model SCI. In order to further enhance the recovery, we here examined combinatorial treatment anti-HMGB1 mAb epot...

BACKGROUND Pancreatic islet encapsulation is one way to address the disadvantages of islet transplantation. Not only does encapsulation involve bidirectional diffusion of nutrients, oxygen, and glucose, but also it protects the graft from the recipient's immune reaction. The high mobility group box 1 (HMGB1), one of higher expression proteins in islet, can be secreted from transplanted islets a...
