Abstract

The systemic RNA interference defective-1 (SID-1) can transport double-stranded RNA (dsRNA) into cytosol across the cytoplasmic membrane. We report here that ectopic expression of Caenorhabditis elegans SID-1 allows BmN4 cells to import extracellular plasmid dsDNA into cells via the direct soaking method. Interestingly, BmN4-SID1 cells incorporate dsRNA and plasmid DNA simultaneously. Furthermore, the ectopic SID-1 allows us to establish a stably transformed cell line by the simple soaking method. Our results provide an alternative method for silkworm gene function analysis with low cost and low cell toxicity.
