In glioblastoma multiforme (GBM), the expression levels of one small non-coding RNA (RNU6-1) and two microRNAs (miR-320 and miR-574-3p) are significantly associated with GBM diagnosis, with RNU6-1 potentially serving as an independent predictor for GBM diagnosis (Manterola et al., 2014). Here, RNU6-1 is linked to glioblastoma.
