Furthermore, we classified patients by age, sex, MGMT (O-6-methylguanine-DNA methyltransferase) promoter methylation status and IDH1 (isocitrate dehydrogenase [NADP(+)] 1, cytosolic) mutation to estimate the prognostic value of the miR-504/FZD7 ratio in stratified GBM cohorts based on the Kaplan–Meier curves. The gene discussed is IDH1; the disease is glioblastoma.
