Terapias dirigidas con inhibidores del braf en gliomas pediátricos de alto y bajo grado con la mutación brafv600e. Experiencia del hospital Prof. Dr. Juan P. Garrahan

Medicina (B.Aires); 81 (5), 2021
Resumen La mutación puntual V600E del gen BRAF juega un papel fundamental en la tumorigénesis de muchos gliomas. La inhibición de su producto forma parte de terapias innovadoras emergentes en los últimos años. Conocer el rol de estos tratamientos resulta imprescindible. El objetivo del trabajo fue d...

Brain Tumor Heterogeneity

Arq. bras. neurocir; 40 (3), 2021
Tumor heterogeneity is the concept that different tumor cells provide distinct biomorphological lesions, gene expressions, proliferation, microenvironment and graduated capacity of metastatic lesions. Brain tumor heterogeneity has been recently discussed about the interesting interaction of chronic infla...

A comprehensive analysis of the angiogenesis-related genes in glioblastoma multiforme vs. brain lower grade glioma

Arq. neuropsiquiatr; 78 (1), 2020
Abstract Brain tumors are one of the most common causes of cancer-related deaths around the world. Angiogenesis is critical in high-grade malignant gliomas, such as glioblastoma multiforme. Objective: The aim of this study is to comparatively analyze the angiogenesis-related genes, namely VEGFA, VEGFB,...

Genetic variants related to angiogenesis and apoptosis in patients with glioma

Arq. neuropsiquiatr; 76 (6), 2018
ABSTRACT Background Glioma, the most common primary malignant brain tumor in adults, is highly aggressive and associated with a poor prognosis. The objectives of this study were to evaluate the association of genetic polymorphisms related to angiogenesis and apoptosis with gliomas, as well as comorbidi...

Estudio de mutaciones en los genes IDH1 e IDH2 en una muestra de gliomas de población colombiana

Biomédica (Bogotá); 38 (supl.1), 2018
Resumen Introducción. Los gliomas son los tumores primarios más comunes del sistema nervioso central y se clasifican de I a IV según su grado de malignidad. En recientes investigaciones se ha encontrado que su aparición está relacionada con mutaciones en el exón 4 de los genes que codifican las d...

Translatômica aplicada ao descobrimento de alterações moleculares em gliomas

O glioblastoma (GBM) está entre os tipos tumorais mais agressivos e de menor resposta a terapias, o que requer, portanto, uma melhor compreensão sobre o comportamento deste tipo tumoral, auxiliando no desenvolvimento de novos tipos de tratamento para a doença. Atualmente, dados de expressão gênica e...

Bioinformatics analysis of microarray data to reveal the pathogenesis of diffuse intrinsic pontine glioma

Biol. Res; 51 (), 2018
BACKGROUND: Diffuse intrinsic pontine glioma (DIPG) is the main cause of pediatric brain tumor death. This study was designed to identify key genes associated with DIPG. METHODS: The gene expression profile GSE50021, which consisted of 35 pediatric DIPG samples and 10 normal brain samples, was downloaded...
