In order to more thoroughly analyze aberrant DNA methylation in glioma, we applied a large cohort methylation microarray including 119 glioma samples. Six genes, ADCY1, KAZALD1, KLF4, SLMAP, TETRAN and TP53INP1, were screened out through significance analysis of microarray (SAM), survival Cox-regression and certain other pre-set conditions. We focused on the KAZALD1 oncogene. KAZALD1, also know...

Introduction: Malignant astrocytic gliomas are the most common and lethal brain malignancies due to their refractory to the current therapies. Nowadays, molecular targeted therapy has attracted great attention in treatment of glioma. Connexin 43 (Cx43) and micro ribonucleic acid- 21(miR-21) are among molecules that are involved in glioma development and progression. These molecules showed...

Noninvasive imaging methods, including positron emission tomography (PET), have become essential for diagnosis and staging of gliomas, and monitoring of treatment response. The utility of these techniques have been found to be highly dependent on tumor grade. According to the World Health Organization (WHO) classification of tumors (Kleihues and Sobin 2000), gliomas are classified into 3 main h...

Hypermethylation of tumor suppressor promoters is generally accepted to indicate poor prognosis in glioma; however, the DNA methylation patterns associated with different glioma prognoses remain to be elucidated. In the present study, promoter methylation and gene expression microarrays were used to screen candidate genes between different grades of glioma. Survival analysis was performed using...

Growing evidence shows that deregulation of the circadian clock plays an important role in the development of malignant tumors, including gliomas. However, the molecular mechanisms of gene chnages controlling circadian rhythm in glioma cells have not been explored. Using real time polymerase chain reaction and immunohistochemistry techniques, we examined the expression of two important clock ge...

Insulin-like growth factor binding protein 2 (IGFBP-2) is a malignancy-associated protein measurable in tumors and blood. Increased IGFBP-2 is associated with shortened survival of advanced glioma patients. Thus, we examined plasma IGFBP-2 levels in glioma patients and healthy controls to evaluate its value as a plasma biomarker for glioma. Plasma IGFBP-2 levels in 196 patients with newly diagn...

to investigate the effects of the two-pore-domain potassium (k2p) channel task-3 in a syngeneic murine model for malignant glioma. malignant or high-grade glioma (who grade iii and iv) are the most common and most aggressive primary brain tumors in adults. despite aggressive multimodal therapy, the outcome of patients with malignant glioma remains poor. however, recent phase i and ii trials hav...

PURPOSE To determine whether the changes of [Cho/NAA] ratio in patients with glioma, measured by dynamic 1H-MRS can be used to differentiate between high-grade and low-grade gliomas. MATERIALS AND METHODS This prospective study was approved by the institutional ethics committee. Written informed consent was obtained. Forty-nine patients with biopsy-proven glioma and 20 normal control subjects...
