A microRNA polycistron as a potential human oncogene. Lin He, J. Michael Thomson, Michael T. Hemann, Eva Hernando-Monge, David Mu. This article reports that a group of microRNAs expressed from a single transcription unit (polycistron) has the potential to act as a human ‘oncogene’.

We next analysed these tumours for miRNA expression profiling. From This Paper Figures, tables, and topics from this paper. Several of the be distinguished by an absence of apoptosis that was otherwise expressed-sequence-tags ESTs derived from c13orf25 and its prevalent in c-myc-induced lymphomas. Here we compared B-cell lymphoma samples and cell lines to normal tissues, and found that the levels of the primary or mature microRNAs derived from the mir locus are often substantially increased pklycistron these cancers.

We acquired four cell lines previously described as Nascent primary miRNA transcripts pri-miRNAs are processed carrying amplifications in the 13qq32 region1 and confirmed the sequentially by two RNase III enzymes, Drosha oncogenf Dicer2,3, to yield gene dosage increase at the c13orf25 locus in three of those cell lines mature miRNAs, ranging from 18 to 24 nucleotides nt in length.

Received 15 February; accepted 16 March oncogeme Identification and characterization of a novel gene, C13orf25, as a laboratories for discussions and input. To date, more than microRNAs have been described in humans; however, the precise functions of these regulatory, non-coding RNAs remains largely obscure.
