Integrative transcriptomics and proteomics analysis provide a deep insight into goose astrovirus-host interactions during GAstV infection.

Goose astrovirus (GAstV) is a newly discovered astrovirus. GAstV causes gout and death in 4- to -16-day-old goslings. For the past few years, fatal gout, the cardinal clinical symptom of gosling infected with GAstV, has been spreading rapidly in some goose Chinese farms, which caused continuous economic losses to the goose breeding industry in China.

The aim of this study was to evaluate the relationship between Gal-3 plasma levels and prognosis in a group of aSAH patients.

Early expression of serum neutrophil gelatinase-associated lipocalin (NGAL) is associated with neurological severity immediately after traumatic brain injury.

Purpose: Intracranial bleeding and inflammatory reactions are common consequences of traumatic brain injury (TBI). Neutrophil gelatinase-associated lipocalin (NGAL), an iron-handling and acute phase protein, may participate in the pathogenesis of TBI. Therefore, we hypothesize that NGAL may be of high diagnostic and therapeutic relevance in the prognosis of TBI.

Inhibition of the Rac1-WAVE2-Arp2/3 signaling pathway promotes radiosensitivity via downregulation of cofilin-1 in U251 human glioma cells.

The Ras-related C3 botulinum toxin substrate 1 (Rac1)-WASP-family verprolin-homologous protein-2 (WAVE2)-actin-related protein 2/3 (Arp2/3) signaling pathway has been identified to be involved in cell migration and invasion in various types of cancer cell. Cofilin‑1 (CFL‑1), which is regulated by the Rac1‑WAVE2‑Arp2/3 signaling pathway, may promote radioresistance in glioma. Therefore, the present study aimed to investigate the potential role of the Rac1‑WAVE2‑Arp2/3 signaling pathway in radioresistance in U251 human glioma cells and elucidate its affect on CFL‑1 expression.

Deferoxamine Attenuated the Upregulation of Lipocalin-2 Induced by Traumatic Brain Injury in Rats.

Intracranial hemorrhage is one of the most common consequences of traumatic brain injury (TBI). The release of iron from the breakdown of hemoglobin during intracerebral hematoma resolution results in an increase in perihematomal non-heme iron. Lipocalin 2 (LCN-2) is a siderophore-binding protein that mediates transferrin-independent iron transport.

Deferoxamine attenuates acute hydrocephalus after traumatic brain injury in rats.

Acute post-traumatic ventricular dilation and hydrocephalus are relatively frequent consequences of traumatic brain injury (TBI). Several recent studies have indicated that high iron levels in brain may relate to hydrocephalus development after intracranial hemorrhage. However, the role of iron in the development of post-traumatic hydrocephalus is still unclear.

Phosphoglycerate kinase 1 (PGK1) has been found to be increased in radioresistant astrocytomas. The present study was designed to investigate the potential role of PGK1 in the radioresistance in U251 human cells. Quantitative PCR and western blot analysis were performed to evaluate PGK1 expression for mRNA levels and protein levels, respectively.

Increasing evidence indicates that sterile inflammatory response contributes to secondary brain injury following traumatic brain injury (TBI). However, the specific mechanisms remain largely unknown, as is whether CD24, known as an important regulator in the non-infectious inflammatory response, plays a role in secondary brain injury after TBI. Here, the expression of CD24 was detected in samples from patients with TBI by quantitative real-time polymerase chain reaction (PCR), western blotting, immunohistochemistry and immunofluorescence.

Several methods to induce therapeutic hypothermia have been established; however, most of them are not clinically feasible for stroke patients.

Recombinant high-mobility group box 1 protein (HMGB-1) promotes myeloid differentiation primary response protein 88 (Myd88) upregulation in mouse primary cortical neurons.

Myeloid differentiation primary response protein 88 (Myd88) is a vital factor for inflammation and immunity, and high-mobility group box 1 protein (HMGB-1) can be released from neurons after injury and may contribute to the initial stages of inflammatory response. Therefore, the current study was intended to investigate the expression of Myd88 in cultured neurons following recombinant HMGB-1 (rHMGB-1) addition and to clarify the potential role of Myd88 after neuron injury in vitro. The cultured neurons were randomly divided into six groups: control group and rHMGB-1 groups at hours 1, 6, 12, 24, and 48.

Previous studies indicate that administration of recombinant human erythropoietin (rhEPO) protects cortical neurons following traumatic brain injury (TBI). The mechanisms of rhEPO's neuroprotection are complex and interacting, including anti-apoptosis. Here we aim to demonstrate the role of janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) pathway on the anti-apoptotic effect of rhEPO in Feeney free falling TBI model.

This study was designed to investigate the protective effects of EP against secondary brain injury in rats after Traumatic Brain Injury (TBI).

Activation of JAK2/STAT pathway in cerebral cortex after experimental traumatic brain injury of rats.

The janus kinase/signal transducer and activator of transcription (JAK/STAT) is one of the main pathways downstream of cytokine receptors and growth factor receptors by transducing signals from cell surface to the nucleus. In this study, we aimed to survey the role of JAK2/STAT pathway in the progress of TBI. Right parietal cortical contusion in rats was induced by the Feeney free falling model.

Expression of myeloid differentiation primary response protein 88 (Myd88) in the cerebral cortex after experimental traumatic brain injury in rats.

A growing body of evidence indicates that Toll-like receptors (TLRs) and Interleukin-1 (IL-1) family have been shown to be involved in the damaging inflammatory processes associated with stroke, infection, neoplasia, and other diseases in the central nervous system. Myeloid differentiation primary response protein 88 (Myd88) is a critical adaptor protein that transmits signals for TLRs and IL-1 family. Therefore, this study aimed to detect the expression of Myd88 protein and mRNA in a rat weight-dropping trauma model and to clarify the role of Myd88 after traumatic brain injury (TBI).
