FOXO1 and glioblastoma: Several genes have been confirmed as potential targets of mature miR-27a in a variety of cell types including Sprouty2 [7], prohibitin [4], ZBTB10 [8], FOXO1 [8], HIPK2 [10], but miR-27a has recently been reported to suppress the clonogenic growth and migration of human glioblastoma multiforme cells by targeting BTG2, a p53-inducible anti-proliferation gene and a tumor suppressor gene [32, 33].
