The transcriptional coactivator with PDZ-binding motif (TAZ) is one of the important downstream effectors of Hippo pathway. In this study, the potential implication of TAZ in gliomagenesis was explored. TAZ expression was identified to be upregulated in glioma specimens and positively correlated with tumor grade. Meanwhile, its expression in nucleus was increased more significantly with the asc...
Glioma is the most frequent primary brain tumor of adults that has a presumably glial origin. Although our knowledge regarding molecular mechanisms and signaling pathways involved in gliomagenesis has increased immensely during the past decade, high-grade glioma remains a lethal disease with dismal prognosis. The failure of current therapies has to a large extent been ascribed the functional he...
OBJECTIVES To investigate the expression of cyclinD1 and Ki-67 proteins in gliomas and its significance. PATIENTS AND METHODS The immunohistochemistry was used to detect the expression of cyclinD1 and Ki-67 proteins in 18 cases of normal brain tissues, 32 cases of low-grade gliomas, and 24 cases of high-grade gliomas. RESULTS The cyclinD1 positive ratio in normal brain tissues, low-grade gl...
Fibroblast growth factor receptor 2 (FGFR-2) contributes to the progression of numerous types of cancers; however, its role in glioma has yet to be determined. We investigated the expression of FGFR-2 and its predominant isoforms, FGFR-2 IIIb and FGFR-2 IIIc, in gliomas of all histological grades. Using immunohistochemistry, we demonstrated that FGFR-2, FGFR-2 IIIb and FGFR-2 IIIc were expresse...
BACKGROUND/AIM While neuron-glia 2 (NG2) is well-characterized in the developing brain and in adult high-grade gliomas, little is known about NG2 expression in paediatric brain tumors. Here, NG2 expression was examined in a range of paediatric brain tumors. MATERIALS AND METHODS A retrospective immunohistopathological analysis of 57 paediatric brain tumor biopsies of various tumor types was c...
Background: Gliomas are the most common primary neoplasms of the central nervous system. Relative cerebral blood volume (rCBV) could estimate high-grade Gliomas computed with dynamic susceptibility contrast MR imaging which it is artificially lowered by contrast extravasation through a disrupted blood-brain barrier. Objectives: Our intent was to clarify the usefulness of diffusion-weighted m...
according to research, academic self-concept and academic achievement are mutually interdependent. in the present study, the aim was to determine the relationship between the academic self-concept and the academic achievement of students in english as a foreign language and general subjects. the participants were 320 students studying in 4th grade of high school in three cities of noor, nowshah...
BACKGROUND Radiotherapy plays a major role in the management of high grade glioma. However, the radioresistance of glioma cells limits its efficiency and drives recurrence inside the irradiated tumor volume leading to poor outcome for patients. Stereotactic hypofractionated radiotherapy is one option for recurrent high grade gliomas. Optimization of hypofractionated radiotherapy with new radios...
Gliomas are a highly heterogeneous group of brain tumours that are refractory to treatment, highly invasive and pro-angiogenic. Glioblastoma patients have an average survival time of less than 15 months. Understanding the molecular basis of different grades of glioma, from well differentiated, low-grade tumours to high-grade tumours, is a key step in defining new therapeutic targets. Here we us...
