Abstract

Although there are genetic and proteomic studies of gliomas which allow the subdivision of tumours into several groups: mesenchymal, classical, neural, proneural and its G-CIMP subgroup, these data have not had the expected impact on the emergence of new and more effective targeted treatments for glioma patients. Previous studies in our group have identified altered profiles of bioactive lipids of the eicosanoid family between brain tumours of low and high degrees of malignancy. This project aims to expand the knowledge obtained from samples of primary tumours in order to identify which of the eicosanoids (prostaglandins, hydroxyoctadecadienoic, hydroxyeicosatetraenoic and hydroxyeicosapentaenoic acids) have real importance in glioma cell biology. The main objective of the project is to evaluate, in gliomas, the importance of eicosanoids for (i) the control of cell proliferation and cell death, (ii) the control of cell migration and invasion, and (iii) control of the multiple drug resistance phenomena. Based on our previous data and the scant literature on cyclooxygenases, lipoxygenases and multidrug resistance proteins, we believe that manipulation of the eicosanoid levels and their metabolism may have a positive influence on the response of gliomas to chemotherapeutic agents. We hope in this project to identify eicosanoids which will serve as novel targets for the development of effective adjuvant treatments. (AU)
