Figure 1. Identification of DEMs in glioma. Heat Map showing the miRNA expression profiles in LGG and HGG according to P values, downloaded from (A) GSE42657 and (B) TCGA datasets. (C) Venn diagram of overlapping DEMs from intersection of GSE42657 and TCGA databases. Six overlapping DEMs were identified. (D) Relative expression of miR-1298-3p in tumor tissues of patients with LGG and HGG (n = 40). *P < 0.01 compared with the low-grade group.
