Abstract:

The present invention provides nucleic acids that include a nucleotide sequence that encodes an siRNA, which nucleotide sequence is operably linked to a target cell-specific promoter RNA polymerase II promoter. The present invention further provides vectors, including expression vectors, which include a subject nucleic acid; and host cells that harbor a subject nucleic acid or a subject expression vector. The present invention further provides methods of modulating (e.g., reducing) expression of a gene in a target cell-specific manner, the methods generally involving introducing into a cell a subject expression vector.
