Immunoglobulin genes implicated in glioma risk
Pandey, JP; Kaur, N; Costa, N; Amorim, J; Nabico, R; Linhares, P; Vaz, R; Viana-Pereira, M; Reis, RMBoth genetic and environmental factors are thought to be causal in gliomagenesis. Several genes have been implicated in glioma development, but the putative role of a major immunity-related gene complex member, immunoglobulin heavy chain γ (IGHG) has not been evaluated. Prior observations that IGHG-encoded γ marker (GM) allotypes exhibit differential sensitivity to an immunoevasion strategy of cytomegalovirus...
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...

Analysis of EGFR overexpression, EGFR gene amplification and the EGFRvIII mutat...
Viana-Pereira, M; Lopes, JM; Little, S; Milanezi, F; Basto, D; Pardal, F; Jones, C; Reis, RMBACKGROUND: Patients with malignant gliomas do not respond to any current therapy. Epidermal growth factor receptor (EGFR) controls several oncogenic processes, being frequently up-regulated in gliomas due to overexpression, gene amplification and gene mutation. EGFR inhibitors are being tried in gliomas, yet the molecular determinants of therapeutic response are unclear. MATERIALS AND METHODS: EGFR overexpress...
