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.
