Abstract in Portuguese
O glioblastoma (GBM) é o tumor mais frequente do sistema nervoso central com um alto grau de malignidade e um prognóstico desfavorável. Apesar dos avanços nas técnicas cirúrgicas e de radioterapia e/ou quimioterapia, não há tratamento eficiente disponível para o GBM. Os prostanoide são derivados do ácido araquidônico e estão envolvidas com vários processos do desenvolvimento e progressão do câncer. O objetivo deste estudo foi analisar in vitro o perfil de diferentes prostanoides nas linhagens de GBM. Além de analisar o papel dos prostanoides e dos receptores na migração celular de GBM. Os resultados demostraram um perfil dos prostanoides da série 2 diferente entre as linhagens, além da expressão dos genes envolvidos na biossíntese de PGE2. Nos ensaios de migração os dados demostraram que os tratamentos realizados com os prostanoides exógenos aumentaram a migração celular e os tratamentos com os antagonistas de EP2 e EP4 diminuiram a migração. Em conjunto esses resultados, demonstram o papel importante dos prostanoides, especialmente PGE2, no processo de migração das células de GBM.

Abstract in English
Glioblastoma (GBM) is the most common tumor of the central nervous system with a high degree of malignancy and poor prognosis. Despite advances in surgical techniques and radiation therapy and/or chemotherapy, there is no effective treatment available for GBM. The prostanoid are derived from arachidonic acid and are involved in many processes of development and progression of cancer. The aim of this study was to analyze in vitro profile of different prostanoids in the lines of GBM. In addition to analyzing the role of prostanoids and receptors on the cell migration of GBM. The results showed a profile of series 2 prostanoids the different between the cell lines, in addition to expression of genes involved in the biosynthesis of PGE2. In migration testing data showed that the treatments performed with exogenous prostanoids increased cell migration and treatment with antagonists of EP2 and EP4 decreased migration. Together these results demonstrate the important role of prostanoids, especially PGE2, in the migration process of the GBM cells.
