Provides small RNA (smRNA) sequencing in human cancer research. YM500 not only focuses on miRNAs but also on other functional small non-coding RNAs (sncRNAs), such as PIWI-interacting RNAs (piRNAs), tRNA-derived fragments (tRFs), small nuclear RNAs (snRNAs) and small nucleolar RNAs (snoRNAs). YM500 contains more than 11000 cancer-related smRNA and 10000 RNA-seq datasets. YM500, through its web interface, allows users to: (i) search for small RNA expression, (ii) search for miRNA Isoform, (iii) search for Novel miRNA, (iv) search for miRNA’s arm switching, (v) drive meta-analysis, (vi) drive survival analysis, (vii) drive cancer analysis, (viii) download their results.
