To attain a greater understanding of the expression profile and prognostic significance of UBE2M and UBE2F in human cancers, we examined their expression with the aid of Tumor Immune Estimation Resource (TIMER) online database, an interactive platform that allows users to conduct in-depth studies of TCGA gene expression profiles (http://timer.cistrome.org/). The gene discussed is UBE2M; the disease is neoplasm.
