Methods and compositions for RNA interference
Abstract
The present invention provides methods for attenuating gene expression in a cell, especially in a mammalian cell, using gene-targeted double stranded RNA (dsRNA), such as a hairpin RNA. The dsRNA contains a nucleotide sequence that hybridizes under physiologic conditions of the cell to the nucleotide sequence of at least a portion of the gene to be inhibited (the "target" gene).
