EZH2 elicits CD8 T-cell desert in esophageal squamous cell carcinoma via suppressing CXCL9 and dendritic cells.

CD8 T cell spatial distribution in the context of tumor microenvironment (TME) dictates the immunophenotypes of tumors, comprised of immune-infiltrated, immune-excluded and immune-desert, discriminating "hot" from "cold" tumors. The infiltration of cytotoxic CD8 T cells is associated with favorable therapeutic response. Hitherto, the immunophenotypes of esophageal squamous cell carcinoma (ESCC) have not yet been comprehensively delineated.

Neuregulin 1 enhances cell adhesion molecule L1 like expression levels and promotes malignancy in human glioma.

Neural cell adhesion molecular L1-like protein (CHL1) is a member of the cell adhesion molecule L1 family and serves an important role in the development and progression of tumors. The cytokine neuregulin 1 (NRG1) has been indicated in the tumorigenesis and promotion of metastasis through the modulation of L1. However, the roles of NRG1 in regulating CHL1 in glioma have not been elucidated.

Trimebutine Promotes Glioma Cell Apoptosis as a Potential Anti-tumor Agent.

Gliomas are the most common primary brain tumors with a usually fatal malignancy. They are associated with a poor prognosis although multiple therapeutic options have been available. Trimebutine is one of the prokinetic agents and it has been mainly used for treatment of disorders of the gastrointestinal (GI) tract such as irritable bowel syndrome.

Quercetin promotes cell apoptosis and inhibits the expression of MMP-9 and fibronectin via the AKT and ERK signalling pathways in human glioma cells.

Gliomas are the most common and malignant primary brain tumours and are associated with a poor prognosis despite the availability of multiple therapeutic options. Quercetin, a traditional Chinese medicinal herb, is an important flavonoid and has anti-cancer activity. Here, we evaluated whether quercetin could inhibit glioma cell viability and migration and promote apoptosis.

HMGB1 contributes to regeneration after spinal cord injury in adult zebrafish.

High mobility group box 1 (HMGB1, also called amphoterin) facilitates neurite outgrowth in early development, yet can exacerbate pathology and inhibit regeneration by inducing adverse neuroinflammation when released from dying cells, suggesting that HMGB1 plays a critical, yet undefined role in neuroregeneration. We explored whether HMGB1 contributes to recovery after complete spinal cord transection in adult zebrafish. Quantitative PCR and in situ hybridization revealed that HMGB1 mRNA levels decreased between 12 h to 11 days after spinal cord injury (SCI), then returned to basal levels by 21 days.

[Expression of gdnf and nos in adult zebrafish brain during the regeneration after spinal cord injury].

Recently, it is unclear about the mechanism of notable regenerated ability of adult zebrafish after spinal cord injury. To investigate the effects of brain on restoration from spinal cord injury, adult zebrafish spinal cord injury model was built and brain samples were dissected at different time points after the injury. Real-time quantitative PCR and in situ hybridization were applied to reveal the dynamics of glial cell line-derived neurotrophic factor (gdnf) and nitric oxide synthases (nos) mRNA expression in various regions of zebrafish brain.

The cell neural adhesion molecule contactin-2 (TAG-1) is beneficial for functional recovery after spinal cord injury in adult zebrafish.

The cell neural adhesion molecule contactin-2 plays a key role in axon extension and guidance, fasciculation, and myelination during development. We thus asked, whether contactin-2 is also important in nervous system regeneration after trauma. In this study, we used an adult zebrafish spinal cord transection model to test the functions of contactin-2 in spinal cord regeneration.

Antibody fragments directed against different portions of the human neural cell adhesion molecule L1 act as inhibitors or activators of L1 function.

The neural cell adhesion molecule L1 plays important roles in neuronal migration and survival, neuritogenesis and synaptogenesis. L1 has also been found in tumors of different origins, with levels of L1 expression correlating positively with the metastatic potential of tumors. To select antibodies targeting the varied functions of L1, we screened the Tomlinson library of recombinant human antibody fragments to identify antibodies binding to recombinant human L1 protein comprising the entire extracellular domain of human L1.

Major vault protein promotes locomotor recovery and regeneration after spinal cord injury in adult zebrafish.

In contrast to mammals, adult zebrafish recover locomotor functions after spinal cord injury (SCI), in part due to axonal regrowth and regeneration permissivity of the central nervous system. Upregulation of major vault protein (MVP) expression after spinal cord injury in the brainstem of the adult zebrafish prompted us to probe for its contribution to recovery after SCI. MVP is a multifunctional protein expressed not only in many types of tumours but also in the nervous system, where its importance for regeneration is, however, unclear.

A surgery protocol for adult zebrafish spinal cord injury.

Adult zebrafish has a remarkable capability to recover from spinal cord injury, providing an excellent model for studying neuroregeneration. Here we list equipment and reagents, and give a detailed protocol for complete transection of the adult zebrafish spinal cord. In this protocol, potential problems and their solutions are described so that the zebrafish spinal cord injury model can be more easily and reproducibly performed.

Mismatch repair, minichromosome maintenance complex component 2, cyclin A, and transforming growth factor β receptor type II as prognostic factors for colorectal cancer: results of a 10-year prospective study using tissue microarray analysis.

Background: The expression of genes encoding a number of pathogenetic pathways involved in colorectal cancer could potentially act as prognostic markers. Large prospective studies are required to establish their relevance to disease prognosis.

Methods: We investigated the relevance of 19 markers in 790 patients enrolled in a large randomised trial of 5-fluorouracil using immunohistochemistry and chromogenic in situ hybridisation.
