Abstract |
Long hairpin dsRNA transcribed from chromosomal DNA can induce RNA interference in Bombyx mori cells, although its gene silencing efficiency is lower than that of exogenously introduced double-stranded RNAs (dsRNAs). To solve this problem, we monitored the nuclear cytoplasmic translocation of the transcribed hairpin dsRNA and analyzed the processing efficiency into mature small interfering RNA (siRNA). Northern blot analysis revealed that the transcribed hairpin dsRNAs were spliced and transported into the cytoplasm, but were not effectively diced into siRNAs. Interestingly, RNAi with hairpin dsRNAs from genome-integrated IR transgene was stimulated by the coexpression of Escherichia coli RNase III, although this exogenous enzyme seemed to bring about nonspecific cleavage of cellular mRNA.
