ABSTRACT
Glioblastoma represents the most lethal brain tumor in adults. Several studies have shown the key role of phospholipase C ß1 (PLCß1) in the regulation of many mechanisms within the central nervous system suggesting PLCß1 as a novel signature gene in the molecular classification of high-grade gliomas. This study aims to determine the pathological impact of PLCß1 in glioblastoma, confirming that PLCß1 gene expression correlates with glioma's grade, and it is lower in 50 glioblastoma samples compared to 20 healthy individuals. PLCß1 silencing in cell lines and primary astrocytes, leads to increased cell migration and invasion, with the increment of mesenchymal transcription factors and markers, as Slug and N-Cadherin and metalloproteinases. Cell proliferation, through increased Ki-67 expression, and the main survival pathways, as ß-catenin, ERK1/2 and Stat3 pathways, are also affected by PLCß1 silencing. These data suggest a potential role of PLCß1 in maintaining a normal or less aggressive glioma phenotype.
