TCGA and GTEx gene expression data showed that MIR155HG is overexpressed in a variety of tumors and that high expression of MIR155HG is strongly associated with better survival in cholangiocarcinoma, lung adenocarcinoma, and cutaneous melanoma, while its overexpression is associated with worse survival in glioblastoma, renal clear cell carcinoma, glioma, and uveal melanoma [19]. The gene discussed is MIR155HG; the disease is glioblastoma.
