EGR2 and glioblastoma: LINC00470 and EGR2 expression in specimens of patients with glioblastoma were measured using qRT‐PCR, and a remarkable positive correlation between LINC00470 and EGR2 was observed by the Pearson's correlation coefficient analysis (Figure 1I), which suggested that LINC00470 most likely exerted regulatory functions through EGR2.
