abstract：:Processing of microRNAs (miRNAs) from their precursors to their biologically active mature forms is regulated during development and cancer. We show that mouse pri- or pre-miR-151 can bind to and compete with mature miR-151-5p and miR-151-3p for binding sites contained within the complementary regions of the E2f6 mRNA...
