Finally, the results of the TIMER database suggested that in LGG patients, several immune cells influenced patients prognosis and were associated with METTL7B expression, while these results were not consistent in GBM, suggesting the complex mechanisms of METTL7B in glioma and the latent function difference of METTL7B between LGG and GBM. This evidence concerns the gene TMT1B and glioma.
