In addition, we analysed whether CUL7 expression was correlated with some molecular genetic characteristics, including IDH1 mutations, MGMT promotor methylation, 1p/19q codeletion, low TERT expression level, and ATRX mutations, because these factors have been found to be associated with a beneficial prognosis in gliomas [23, 24]. Here, ATRX is linked to central nervous system cancer.
