EEF1AKMT3 and glioma: In our research, by using The Cancer Genome Atlas (TCGA), the Chinese Glioma Genome Atlas (CGGA), Rembrandt dataset and Gravendeel/GSE16011 dataset, we assessed the expression level (in conjunction with experimental examination of LGG patient samples), methylation level and copy-number variations of METTL21B in LGG tissues, analyzed the association between prognosis and expression of METTL21B, and explored the underlying molecular mechanisms of METTL21B in LGG.
