MGMT and central nervous system cancer: The integrative study identified DNA methylation markers that could lead to the downregulation of some genes involved in important cellular functions in ATRX-low tumors: MGMT, TYMS, CLN8, PANK2 and BNIP3. We also identified that, in glioma cell line, the knockdown of ATRX expression induced apoptotic cells increasing, reduced tumor cell proliferation and repressed the cell migration.
