Impact of EGFR genetic variants on glioma risk and patient outcome
Costa, BM; Viana-Pereira, M; Fernandes, R; Costa, S; Linhares, P; Vaz, R; Pinheiro, C; Lima, J; Soares, P; Silva, A; Pardal, F; Amorim, J; Nabiço, RBACKGROUND: The epidermal growth factor receptor (EGFR) regulates important cellular processes and is frequently implicated in human tumors. Three EGFR polymorphisms have been described as having a transcriptional regulatory function: two single-nucleotide polymorphisms in the essential promoter region, -216G/T and -191C/A, and a polymorphic (CA)(n) microsatellite sequence in intron 1. We aimed to elucidate the...

Prognostic value of MGMT promoter methylation in glioblastoma patients treated ...
Costa, BM; Caeiro, C; Guimarães, I; Martinho, O; Jaraquemada, T; Augusto, I; Castro, l; Osório, L; Linhares, P; Honavar, M; Resende, M; Nabiço, RGlioblastoma (GBM) is the most common and aggressive primary brain tumor. The identification of novel molecular prognostic markers of GBM has recently been an area of great interest in neuro-oncology. The methylation status of the MGMT gene promoter is currently a promising molecular prognostic marker, but some controversial data have precluded its clinical use. We analyzed MGMT methylation by methylation-speci...

Association between functional EGF+61 polymorphism and glioma risk
Costa, BM; Ferreira, P; Costa, S; Canedo, P; Oliveira, P; Silva, AI; Pardal, F; Suriano, G; Machado, JC; Lopes, JM; Reis, RMPURPOSE: Epidermal growth factor (EGF) plays a critical role in cancer. A polymorphism in the EGF gene (EGF+61) may influence its expression and contribute to cancer predisposition and aggressiveness. In the present study, we aimed to elucidate the role of EGF+61 in glioma susceptibility and prognosis. EXPERIMENTAL DESIGN: A case-control study involving 197 glioma patients and 570 controls was done. Univariate ...
