ULK2 and central nervous system cancer: Previous studies have reported correlations between miR-7, PI3K/AKT, mTOR, and ULK2 in various cancers [48–50], but, to our knowledge, none have explored these correlations based on glioma gradesmiR-7 not only inhibits autophagy by directly repressing ULK2 but, also targets LKB1-AMPK-mTOR signaling pathway thus inducing cell proliferation [49].
