Abstract

Glioblastoma multiforme (GBM) is one of the most aggressive tumor types, with a median survival time of 15 months. Furthermore, current treatments are not able to prevent tumor recurrence in most cases. Understanding basic aspects of tumor biology, such as its origin, development and resistance is crucial to develop more effective therapies. RNA binding proteins (RBPs) are among the molecules involved in the genesis and development of the GBM. RBPs are critical post-transcriptional gene expression regulators. They are implicated in several cellular processes, like mRNA and miRNA processing, stability, degradation, polyadenylation, translation and splice site selection. Changes in their expression levels may cause severe alterations in the cellular proteome, which will lead to diseases states and tumorigenesis. Here, we propose to investigate the influence of changes in expression of RBPs and RNA processing events in the development and resistance of GBM using isolated Glioma Stem Cells (GSCs) which will be explored with RNA-Seq, bioinformatics analysis and biological assays to access tumorigenic potential. Therefore, we expected to improve our knowledge regarding the influence of RBPs and RNA processing events in the GBM development and resistance. (AU)
