Meanwhile, knockdown of NEAT1 activates miR-let-7e, which acts as a cancer inhibitor by decreasing migration, invasion, and proliferation while increasing apoptosis in glioma stem cells and this leads to downregulation of NRAS protein, an isoform of RAS reported to be mutated in several cancers and known to play an oncogenic role in glioma stem cells, thus inhibiting disease progression [124]. This evidence concerns the gene NRAS and central nervous system cancer.
