Circ_0021350 plays an oncogene role by regulating miR-1207-3p/ PIK3R3 in glioblastoma

To screen differentially expressed circRNAs in GBM, we performed RNA-seq using four tumor tissues from patients with GBM and four normal brain tissues and focused on circ_0021350, which is upregulated in GBM. Comparative gene expression profiling analysis of RNA-seq data for GBM tissues and normal brain tissues
