MIR96-IN-1 targets the Drosha site in the miR-96 (miRNA-96, microRNA-96) hairpin precursor, inhibiting its biogenesis, derepressing downstream targets, and triggering apoptosis in breast cancer cells. MIR96-IN-1 binds to RNAs with Kds of 1.3, 9.4, 3.4, 1.3 and 7.4 μM for RNA1, RNA2, RNA3, RNA4 and RNA5, respectively.
