LINC00645 and glioma: Bioinformatics analysis of GSE490 and TCGA datasets performed by Li et al. [101] showed that LINC00645 expression level was markedly upregulated in glioma samples as compared with normal tissue; additionally, a high level of LINC00645 expression was correlated with poor survival in glioma samples (TCGA and CGGA datasets) as well as in a recruited group of 50 GBM patients.
