TGM2 and glioblastoma: We found that low levels of hsa-miR-17-5p expression are associated with shorter survival of glioblastoma patients in the TCGA cohort (Supplementary Fig. 9A) and that expression of hsa-miR-17-5p is inversely correlated with TGM2 expression in this cohort set (Supplementary Fig. 9B), however, not with HOTAIRM1 expression (Supplementary Fig. 9C).
