Integrate Molecular Phenome and Polygenic Interaction to Detect the Genetic Risk of Ischemic Stroke.

Ischemic stroke (IS) is one of the leading causes of death, and the genetic risk of which are continuously calculated and detected by association study of single nucleotide polymorphism (SNP) and the phenotype relations. However, the systematic assessment of IS risk still needs the accumulation of molecular phenotype and function from the level of omics. In this study, we integrated IS phenome, polygenic interaction gene expression and molecular function to screen the risk gene and molecular function.

Comprehensive analysis of circRNA expression pattern and circRNA-miRNA-mRNA network in the pathogenesis of atherosclerosis in rabbits.

Atherosclerosis is a chronic and multifactorial inflammatory disease and is closely associated with cardiovascular and cerebrovascular diseases. circRNAs can act as competing endogenous RNAs to mRNAs and function in various diseases. However, there is little known about the function of circRNAs in atherosclerosis.

Contrast-Enhanced Ultrasound Imaging Quantification of Adventitial Vasa Vasorum in a Rabbit Model of Varying Degrees of Atherosclerosis.

This study used an atherosclerotic rabbit model to investigate the feasibility of quantifying adventitial vasa vasorum (VV) via contrast-enhanced ultrasound (CEUS) imaging to identify early atherosclerosis. Recent evidence has linked adventitial VV with atherosclerotic plaque progression and vulnerability. A growth in VV density has been detected preceding intimal thickening and even endothelial dysfunction.

Novel CD137 Gene Polymorphisms and Susceptibility to Ischemic Stroke in the Northern Chinese Han Population.

Ischemic stroke is a leading cause of mortality and morbidity worldwide, and atherosclerosis is one of the major risk factors for this neurologic deficit. Recent studies have revealed the important role of CD137 in human atherosclerosis. Here, we analyzed the association of CD137 single nucleotide polymorphisms (SNPs) with ischemic stroke.

A Novel Association of the Suppressor of Cytokine Signaling 1 (SOCS1) Gene Polymorphisms in Ischemic Stroke Patients.

Ischemic stroke is a common neurological disease and a leading cause of permanent disability in many countries. Recent studies provide evidence on the role of the suppressor of the cytokine signaling 1 (SOCS1) gene in the development and progression of atherosclerotic lesions. However, few studies have assessed the association between single nucleotide polymorphisms (SNPs) on SOCS1 gene and ischemic stroke.

KALRN Rare and Common Variants and Susceptibility to Ischemic Stroke in Chinese Han Population.

Stroke is the second most common cause of mortality worldwide, and it is a major cause of physical disability. Several genome-wide association studies have yielded numerous common variants which increase the risk of ischemic stroke, including the Kalirin-coding gene, KALRN. KALRN strongly associates with early-onset coronary artery disease and atherosclerosis and plays an important role in stroke in the European population.

Arachidonate 5-lipoxygenase-activating protein (ALOX5AP) gene rs4073259 polymorphism not associated with ischemic stroke in the northeastern Chinese Han population.

Objective: Although recent evidence has implicated that 5-lipoxygenase activating protein (ALOX5AP) gene is associated with ischemic stroke (IS) risk, the underlying molecular mechanism remains to be defined. This study aimed to investigate the role of ALOX5AP rs4073259 in ischemic stroke in a Northeastern Chinese Han population.

Methods: A total of 501 IS patients and 497 healthy controls were enrolled for polymerase chain reaction (PCR) and ligase detection reaction (LDR) analysis of ALOX5AP rs4073259 single nucleotide polymorphism (SNP).

Association of imaging classification of intracranial cerebral atherosclerotic vascular stenosis in ischemic stroke and renalase gene polymorphisms.

Cerebral atherosclerosis vascular stenosis is a common etiology for ischemic stroke and a major factor in recurrent stroke and vascular mortality. Recent studies suggest that renalase plays a role in hypertension and ischemic stroke, and may be involved in atherosclerosis. The aim of the present study was to investigate whether there were correlations between single-nucleotide polymorphisms (SNPs) in the renalase gene and severity of intracranial cerebral atherosclerotic vascular stenosis in ischemic stroke patients as determined by imaging.

Xeroderma pigmentosum complementation group f polymorphisms influence risk of glioma.

We conducted an exploratory investigation of whether variation in six common SNPs of xeroderma pigmentosum complementation group F (XPF) is associated with risk of glioma in a Chinese population. Six single nucleotide polymorphisms (SNPs) were genotyped in 207 glioma cases and 236 cancer-free controls by a 384-well plate format on the Sequenom MassARRAY platform (Sequenom, San Diego, USA). The rs1800067 G and rs2276466 G allele frequencies were significantly higher in the glioma group than controls.

IDH1 mutation is associated with improved overall survival in patients with glioblastoma: a meta-analysis.

Previous studies proposed that isocitrate dehydrogenase 1 (IDH1) mutation was associated with improved survival in patients with glioblastoma, but those studies reported varying estimates and yielded inconclusive results. The purpose of the present study was to determine the effect of IDH1 mutation on the prognosis of patients with glioblastoma by performing a meta-analysis. Pubmed and Embase databases were searched for eligible studies.

An association study on renalase polymorphisms and ischemic stroke in a Chinese population.

Ischemic stroke is a leading cause of death and adult disability worldwide. Recent research suggests that renalase is strongly associated with heart disease and hypertension and may play a role in ischemic stroke. In this study, we investigate the genetic association between renalase and ischemic stroke in a northern Chinese Han population.

MiR-106a inhibits glioma cell growth by targeting E2F1 independent of p53 status.

MicroRNAs are single-stranded small non-coding RNA molecules which regulate mammalian cell growth, differentiation, and apoptosis by altering the expression of other genes and play a role in tumor genesis and progression. MiR-106a is upregulated in several types of malignancies and provides a pro-tumorigenic effect. However, its role in glioma is largely unknown.

Effects of photodynamic therapy on the ultrastructure of glioma cells.

Objective: To study the change in ultrastructure of C6 glioma cells after photodynamic therapy (PDT), to compare morphological differences in necrosis and apoptosis before and after PDT treatment, and to evaluate the effect of photodynamic therapy on the blood brain tumor barrier (BTB) of C6 glioma.

Methods: The model was produced by transplanting C6 glioma cells cultured in vitro using Peterson method into the caudate nuclei of Wister rats. The experiment group received PDT for two weeks after the operation.
