High expression of XIAP and Bcl-2 may inhibit programmed cell death in glioblastomas
Alta expressão de XIAP e Bcl-2 pode inibir morte celular programada em glioblastomasABSTRACT
Glioblastoma (GBM) is the most malignant glioma and represents 29% of all brain tumors. Tumorigenesis is intimately connected with characteristics acquired in the physiologic pathway of cellular death.
Objective: In the present study, the expression of anti-apoptotic (XIAP and Bcl-2) and apoptotic (cytochrome C, caspase 9, APAF-1), caspase 3 and the Smac/DIABLO genes related to the apoptosis pathway were evaluated in 30 samples of glioblastoma.
Methods: The gene expression was evaluated in 30 glioblastomas (WHO grade IV) and compared to 10 white matter control samples with real-time PCR.
Results and Conclusion: There were higher expressions of XIAP (p = 0.0032) and Bcl-2 (p = 0.0351) in the glioblastoma samples compared to the control samples of normal brain. These results raise the question of whether Bcl-2 and XIAP genes can be responsible for the inhibition of programmed cell death in glioblastomas. Moreover, they provide additional information capable of allowing the development of new target therapy strategies.
RESUMO
O glioblastoma (GBM) é o glioma mais maligno e representa 29% de todos os tumores cerebrais. A tumorigênese está intimamente ligada à características adquiridas na via fisiológica de morte celular.
Objetivo: Avaliar a expressão de genes anti-apoptóticos (XIAP e Bcl-2) e apoptóticos (citocromo C, a caspase 9, APAF-1), caspase 3 e SMAC/DIABLO, relacionados à apoptose, em 30 amostras de tecido de pacientes com glioblastoma.
Métodos: A expressão gênica foi avaliada em trinta glioblastomas e comparada a dez amostras controles de substância branca por PCR em tempo real.
Resultados e Conclusão: Houve maior nível de expressão de XIAP (p = 0,0032) e Bcl-2 (p = 0,0351) em comparação com as amostras controle, de cérebro normal. Estes resultados levantam a questão de que os genes Bcl-2 e XIAP podem ser responsáveis pela inibição da morte celular programada em glioblastomas, além disso, proporcionam informação adicional capaz de permitir o desenvolvimento de novas estratégias de terapia alvo.
