Investigating the shared genetic architecture between anxiety and stroke.

Background: An epidemiological association between anxiety and stroke is well-established; however, the role of shared genetic factors remain unclear. This study aimed to investigate the shared genetic architecture between anxiety and stroke.

Methods: Using public genome-wide association study (GWAS) summary statistics of anxiety and stroke, we performed linkage disequilibrium score regression and super genetic covariance analyzer for global and local genetic correlation studies.

SLC1A5 is a novel biomarker associated with ferroptosis and the tumor microenvironment: a pancancer analysis.

Solute carrier family 1 member 5 (SLC1A5) is a member of the solute carrier (SLC) superfamily of transporters and plays an important role in tumors as a key transporter of glutamine into cells. However, the relationship between SLC1A5, which is involved in immune regulation, and immune cell infiltration in the tumor microenvironment has not been elucidated, and the relationship between SLC1A5 and ferroptosis is rarely reported. Therefore, we comprehensively analyzed the expression level of SLC1A5 across cancers and compared it with that in normal tissues.

Surveillance, Epidemiology, and End Results database and propensity score matching analysis of postoperative radiotherapy for non-malignant meningioma: A retrospective cohort study.

Background: The clinical effect of postoperative radiotherapy (PORT) in non-malignant meningioma (NMM) has not been well explored.

Methods: A total of 8629 patients with NMM (surgery alone group: n = 7716, postoperative radiotherapy group: n = 913) were obtained from the Surveillance, Epidemiology, and End Results database. Patient profiles were matched by 1:1 propensity score matching (PSM).

KDELR2 knockdown synergizes with temozolomide to induce glioma cell apoptosis through the CHOP and JNK/p38 pathways.

Background: The C-terminal tetrapeptide Lys-Asp-Glu-Leu receptors (KDELRs) are transmembrane proteins that regulate ER stress (ERS) response, growth, differentiation, and immune responses. There is an association between KDELR2and promotion of glioblastoma tumorigenesis. The aim of the present study was to explore the functional mechanism of KDELR2 in glioma and during response to chemotherapy to temozolomide (TMZ).

Partial-Brain Radiation-Induced Microvascular Cognitive Impairment in Juvenile Murine Unilateral Hippocampal Synaptic Plasticity.

Purpose: Radiation-induced cognitive deficits have a severe negative impact on pediatric brain tumor patients. The severity of cognitive symptoms is related to the age of the child when radiation was applied, with the most severe effects seen in the youngest. Previous studies using whole-brain irradiation in mice confirmed these findings.

Potential Role of Hsp70 and Activated NK Cells for Prediction of Prognosis in Glioblastoma Patients.

Despite rapid progress in the treatment of many cancers, glioblastoma remains a devastating disease with dismal prognosis. The aim of this study was to identify chaperone- and immune-related biomarkers to improve prediction of outcome in glioblastoma. Depending on its intra- or extracellular localization the major stress-inducible heat shock protein 70 (Hsp70) fulfills different tasks.

Overexpressed miR-183 promoted glioblastoma radioresistance via down-regulating LRIG1.

Background: Glioma is the most common cause of cancer-related death. Therapy based on radiation seemed to effectively, while the radioresistance of several glioblastoma cells abolished the therapy. Thus, to employ the potential mechanism underlying the radioresistance is essential for glioma treatment.

Silymarin prevents NLRP3 inflammasome activation and protects against intracerebral hemorrhage.

Inflammatory response mediates secondary injury during intracerebral hemorrhage (ICH). In the present study, we determined oxidative stress and involvement of NLRP3 in ICH injury and analyzed whether silymarin might offer protective effect against ICH injury. Post 24h after ICH injury there was increased oxidative stress markers (reactive oxygen species (ROS) and lipid peroxides) compared to sham group.

Long noncoding RNA activated by TGF-β in human cancers: A meta-analysis.

Background: Because long non-coding RNA ATB (activated by TGF-β) is dysregulated in many cancers, we performed a meta-analysis to determine its prognostic potential in malignant tumors.

Methods: We searched electronic databases, including PubMed, Medline, OVID, Cochrane Library and Web of Science from inception until November 15, 2016 and identified eight studies with 818 cancer patients for the meta-analysis. We analyzed the hazard ratios (HRs) and 95% confidence intervals (CIs) to determine the relationship between lncRNA-ATB expression and overall survival (OS), recurrence -free survival (RFS), disease-free survival (DFS).

Methylprednisolone sodium succinate reduces BBB disruption and inflammation in a model mouse of intracranial haemorrhage.

Inflammation and disruption of the blood-brain barrier (BBB) cause oedema and secondary brain injury after intracranial haemorrhage (ICH), which is closely related to patient prognosis. Methylprednisolone sodium succinate (MPSS), a well-known immunosuppressive agent, is widely applied in many diseases to inhibit inflammation. In this study, we investigated the effect of MPSS on inflammation and disruption of the BBB in a model mouse of ICH.

Over-expression of LRIG1 suppresses biological function of pituitary adenoma via attenuation of PI3K/AKT and Ras/Raf/ERK pathways in vivo and in vitro.

Pituitary adenomas (PAs) are well known as a common intracranial benign tumor, and a portion of PAs are refractory to current therapeutic methods. ErbB receptors family signaling pathway regulates the expression of PAs activation associated gene. Inhibition of epidermal growth factor receptor (EGFR) can inhibit proliferation of PAs.
