Expresión inmunohistoquímica de homólogo de fosfatasa y tensina en glioblastoma multiforme y su relación con sobrevida

Int. j. morphol; 37 (3), 2019
El glioblastoma multiforme es el subtipo de gliomas más frecuente en adultos, con una pobre sobrevida promedio posterior al diagnóstico incluso si se aplica el tratamiento óptimo. Se ha estudiado marcadores tumorales de buen pronóstico, siendo controversial la expresión del homólogo de fosfatasa y ...

Metastasis from glioblastoma multiforme: a meta-analysis

SUMMARY OBJECTIVE: Extracranial metastases of glioblastoma multiforme (GBM) are rare due to the short survival experienced by the patients. Therefore, the natural history of GBM metastases remains elusive. The identification of clinical factors promoting GBM metastases may help elucidate the mechanisms ...

Systemic dissemination of glioblastoma: literature review

SUMMARY INTRODUCTION: Glioblastoma (GBM) is the most frequent primary malignant tumor from the central nervous system in adults. However, the presence of systemic metastasis is an extremely rare event. The objective of this study was to review the literature, evaluating the possible biological mechanism...

Envolvimento de heat shock protein 90 na ativação de TLR4 em células de gliobastoma murino

O glioblastoma é um tumor cerebral altamente invasivo e de mau prognóstico, derivado da transformação maligna de células-tronco neurais, células precursoras de oligodendrócitos e astrócitos. As células de glioblastoma expressam o receptor de reconhecimento de padrões (PRR) do tipo toll (TLR)4, ...

Therapeutic evaluation of magnetic hyperthermia using Fe3O4-aminosilane-coated iron oxide nanoparticles in glioblastoma animal model

Einstein (Säo Paulo); 17 (4), 2019
ABSTRACT Objective: To evaluate the potential of magnetic hyperthermia using aminosilane-coated superparamagnetic iron oxide nanoparticles in glioblastoma tumor model. Methods: The aminosilane-coated superparamagnetic iron oxide nanoparticles were analyzed as to their stability in aqueous medium and th...

Role of Ectodermal-neural cortex 1 protein in human glioma progression, identification of a peptide internalized by human glioblastoma cells and development of an alternative method to generate growth curves of adherent cultures

Gliomas are the most common form of primary intracranial malignancy, among which astrocytomas are the most frequent. Ectodermal-cortex protein 1 (ENC 1), also known as Nuclear Restricted Protein/Brain (NRP/B), was first characterized as a protein which interacts with the cytoskeleton by binding to actin ...

Survival Analysis in Elderly Patients with Glioblastomas: The Influence of Clinical Status, Tumor and Surgical Features

Arq. bras. neurocir; 37 (4), 2018
Introduction Glioblastomas are malignant neoplasms, notorious for their poor prognosis. We have conducted a survival analysis in a sample of elderly patients with glioblastomas. Methods The sample of the present study consisted of elderly patients consecutively admitted from January 2014 to January 2016 ...

Gliomas malignos: biología molecular y detalles oncogenéticos
Wicked gliomas: molecular biology and oncogenetics detail

Rev. medica electron; 40 (4), 2018
RESUMEN La biología de los gliomas malignos se asocia con el balance de la expresión de las proteínas que controlan de manera positiva o negativa el ciclo celular, la proliferación, la motilidad, la neoformación vascular y el reconocimiento del sistema inmune. La frecuencia de las alteraciones gené...

Expresión de O6-metilguanina-ADN-metiltransferasa (MGMT) en pacientes chilenos con glioblastoma multiforme

Rev. méd. Chile; 146 (1), 2018
Background: Patients with Glioblastoma multiforme (GBM) have a five years survival of less than 5%, but the response to chemotherapy with alkylating agents can vary depending on the methylation status of O6-methylguanine-DNA-methyltransferase (MGMT). Genetic testing has limitations for routine use, while...

Role of the CHD7 chromatin remodeler protein in glioblastoma multiformePalavras-chave em inglês Cell motility

Chromatin remodeler proteins exert an important function in promoting dynamic modifications in the chromatin architecture, rendering the transcriptional machinery available to the condensed genomic DNA. Due to this central role in regulating gene transcription, deregulation of these molecular machines ma...
