EGFR and glioblastoma: So far the alterations of many miRNA have been identified as potential GBM biomarkers, including miR‐21, miR‐221/222, miR‐124, miR‐128, miR‐7, miR‐137, miR‐181, miR‐218, miR‐148a, and miR‐10b.[62] They are involved in regulating the expression of critical GBM‐driving genes such as EGFR (e.g., miR‐7), MGMT (e.g., miR‐181d, miR‐198), and BCL2 (e.g., miR‐7).
