Lithium bidirectionally regulates depression- and mania-related brain functional alterations without worsening cognitive function in patients with bipolar disorder.

Lithium monotherapy has been proposed to have antidepressant and antimanic effects in patients with bipolar disorder (BP). However, so far, it is lack of evidence to support this proposition. The main aim of this study was to test the hypothesis that lithium bidirectionally regulates depression- and mania-related brain functional abnormalities in patients with BP.

Cerebral Intraparenchymal Hemorrhage Changes Patients' Gut Bacteria Composition and Function.

Gut bacteria consists of 150 times more genes than humans that are vital for health. Several studies revealed that gut bacteria are associated with disease status and influence human behavior and mentality. Whether human brain injury alters the gut bacteria is yet unclear, we tested 20 fecal samples from patients with cerebral intraparenchymal hemorrhage and corresponding healthy controls through metagenomic shotgun sequencing.

Systematic Analysis of 4-gene Prognostic Signature in Patients with Diffuse Gliomas Based on Gene Expression Profiles.

Diffuse gliomas are a group of diseases that contain different degrees of malignancy and complex heterogeneity. Previous studies proposed biomarkers for certain grades of gliomas, but few of them have conducted a systematic analysis of different grades to search for molecular markers. WGCNA was used to find significant genes associated with malignant progression of diffuse glioma in TCGA glioma sequencing expression data and the GEO expression profile-merge meta dataset.

Proteomics identifies EGF-like domain multiple 7 as a potential therapeutic target for epidermal growth factor receptor-positive glioma.

Background: Glioma, the most frequent primary tumor of the central nervous system, has poor prognosis. The epidermal growth factor receptor (EGFR) pathway and angiogenesis play important roles in glioma growth, invasion, and recurrence. The present study aimed to use proteomic methods to probe into the role of the EGF-EGFR-angiogenesis axis in the tumorigenesis of glioma and access the therapeutic efficacy of selumetinib on glioma.

KDELR2 is an unfavorable prognostic biomarker and regulates CCND1 to promote tumor progression in glioma.

Background: The KDEL receptor is a seven-transmembrane-domain protein, which plays a key role in ER quality control and in the ER stress response, KDELR2 involved in regulation of cellular functions, including cell proliferation, survival, promotes glioblastoma tumorigenesis. The aim of this study was to investigate the clinicpathological value and biological role of KDELR2 in glioma.

Methods: We studied the expression of KEDLR2 and its association with the prognosis through the TCGA, CGGA, and GSE16011 database.

Integrating Genomic Data with Transcriptomic Data for Improved Survival Prediction for Adult Diffuse Glioma.

: Glioma is the most common type of primary central nervous system tumors. However, the relationship between gene mutations and transcriptome is unclear in diffuse glioma, and there are no systemic analyses with regard to the genotype-phenotype association currently. : We performed the multi-omics analysis in large glioblastoma multiforme (GBM, n=126) and low-grade glioma (LGG, n=481) cohorts obtained from The Cancer Genome Atlas (TCGA) database.

Combined Therapy Sensitivity Index Based on a 13-Gene Signature Predicts Prognosis for IDH Wild-type and MGMT Promoter Unmethylated Glioblastoma Patients.

Glioblastoma (GBM) is one of the lethal tumors with poor prognosis. However, prognostic prediction approaches need to be further explored. Therefore, we developed an evaluation system that could be used for prognostic prediction of GBM patients.

A Novel Prognostic Signature of Transcription Factors for the Prediction in Patients With GBM.

: Although the diagnosis and treatment of glioblastoma (GBM) is significantly improved with recent progresses, there is still a large heterogeneity in therapeutic effects and overall survival. The aim of this study is to analyze gene expressions of transcription factors (TFs) in GBM so as to discover new tumor markers. : Differentially expressed TFs are identified by data mining using public databases.

EGFL7 is an intercellular EGFR signal messenger that plays an oncogenic role in glioma.

Epidermal Growth Factor like domain 7 (EGFL7), also known as Vascular Endothelial-statin (VE-statin), is a secreted angiogenic factor. Recent data have demonstrated the potential oncogenic role and prognostic significance of EGFL7 in several human cancers. However, the clinical signature and further mechanisms of EGFL7's function in gliomagenesis are poorly understood.

VE-statin/Egfl7 siRNA inhibits angiogenesis in malignant glioma in vitro.

This study investigated the role of VE-statin/Egfl7 and its mechanism in angiogenesis in malignant glioma. Transwell culture plates were used to establish an U251-HUVEC co-culture system, which was used to mimic the interaction between malignant glioma and endothelial cells. Lentiviral vectors expressing VE-statin/Egfl7 siRNA were constructed, and U251 cells and HUVECs were transfected to inhibit VE-statin/Egfl7 expression.

VE-statin/Egfl7 expression in malignant glioma and its relevant molecular network.

This study investigated VE-statin/Egfl7 expression and its role and regulatory mechanism in malignant glioma progression. Forty-five paraffin-embedded glioma (grade I-II: n=24; grade III-IV: n=21) were examined. VE-statin/Egfl7 protein expression was detected via immunohistochemistry, and its correlation with pathological grade was evaluated.

Atractylodes macrocephala polysaccharides induces mitochondrial-mediated apoptosis in glioma C6 cells.

In recent years there has been an increasing interest in naturally occurring substances in plant origin that may be used as potential chemopreventive and chemotherapeutic agents to prevent or slow the progression of chronic illnesses, such as cancer. In this study, we aimed at examining the antitumor activity of Atractylodes macrocephala polysaccharide (AMPs) in vitro using glioma C6 cells and the underlying mechanisms were also investigated. The results demonstrated that AMPs significantly inhibited proliferation of C6 cells in a concentration dependent manner by DNA fragmentation and apoptosis induction.

Expression and clinical significance of EGFL7 in malignant glioma.

Purpose: Tumor angiogenesis is an important factor for the continuous growth of human malignancies and can be used to predict the prognosis for patients. In the current study, we examined the expression of EGF-like domain 7 (EGFL7), an endothelial cell-derived secreted factor, in malignant gliomas and explored its clinical significance.

Methods: We determined the steady-state mRNA levels of EGFL7 from 36 fresh glioma samples by semi-quantitative RT-PCR and the protein levels from 45 paraffin-embedded glioma samples by immunohistochemistry, respectively.
