MIR96-IN-1 inhibits Drosha cleavage of pri-miR-96, as evidenced by an increase in the levels of pri-miR-96 and a reduction in levels of pre- and mature miR-96 in treated cells, as expected if MIR96-IN-1 binds to the Drosha site. MIR96-IN-1 efficiently and selectively silences production of miR-96 at 40 μM while not affecting miR-182 or -183. MIR96-IN-1 inhibits biogenesis of its target precursor miRNA to varying extents: MIR96-IN-1 reduces the expression level of miR-96 by 90% at 40 μM [1].
