Provided are DNAs comprising a polynucleotide that encodes at least a first modified miR-30 precursor and a second modified miR-30 precursor. Also provided are vectors comprising the the DNAs, where the vector can replicate in a host cell. Additionally, specific lentiviral vectors comprising the above-described DNA are provided, as are methods of inhibiting expression of a target gene in a eukaryotic cell. |
