Notably, miR-203a-3p was shown to have regulatory effects in oral squamous cell carcinoma (OSCC) and glioma via targeting ATM [16, 17], which is a serine/threonine protein kinase located in chromosome region 11q22–23 [18].In actuality, the abnormal expression of the ATM gene has strong implications for the clinical diagnosis of ovarian cancer, and the overexpression of ATM has been discovered to be closely associated with poor prognosis in ovarian cancer patients [19]. The gene discussed is ATM; the disease is glioma.
