MKI67 and glioma: To identify relationships between miR-320a expression in gliomas and histopathological grades, cell proliferation or patients’ prognoses in the same grade, IDH status, age and KPS groups, ISH and IHC were applied to detect endogenous miR-320a and Ki-67 expressions in the FFPE specimens of 120 gliomas and 20 nontumoral brain tissues from human.
