abstract = {The outcome of patients with anaplastic gliomas varies
considerably depending on single molecular markers, such as
mutations of the isocitrate dehydrogenase (IDH) genes, as
well as molecular classifications based on epigenetic or
genetic profiles. Remarkably, $98\%$ of the RNA within a
cell is not translated into proteins. Of those, especially
microRNAs (miRNAs) have been shown not only to have a major
influence on physiologic processes but also to be
deregulated and prognostic in malignancies.To find novel
survival markers and treatment options we performed unbiased
DNA methylation screens that revealed 12 putative miRNA
promoter regions with differential DNA methylation in
anaplastic gliomas. Methylation of these candidate regions
was validated in different independent patient cohorts
revealing a set of miRNA promoter regions with prognostic
relevance across data sets. Of those, miR-155 promoter
methylation and miR-155 expression were negatively
correlated and especially the methylation showed superior
correlation with patient survival compared to established
biomarkers.Functional examinations in malignant glioma cells
further cemented the relevance of miR-155 for tumor cell
viability with transient and stable modifications indicating
an onco-miRNA activity. MiR-155 also conferred resistance
towards alkylating temozolomide and radiotherapy as
consequence of nuclear factor (NF)κB
activation.Preconditioning glioma cells with an NFκB
inhibitor reduced therapy resistance of miR-155
overexpressing cells. These cells resembled tumors with a
low methylation of the miR-155 promoter and thus mir-155 or
NFκB inhibition may provide treatment options with a
special focus on patients with IDH wild type tumors.},
