WT1 and glioblastoma: Considering the high mortality rate of this tumor and an immediate need for an efficient strategy for its therapy (Smoll et al., 2013; Thakkar et al., 2014; Ostrom et al., 2015), elucidating potential roles of WT1 and its potential interaction with TETs/oxi-mCs in glioblastomas should represent an important direction for future research.
