Research results from K. Fujita and colleagues update understanding of RNA research

Published in Gene Therapy Weekly, November 12th, 2009

"Gene-knockdown technology using RNA interference (RNAi) is widely used to characterize gene functions in many organisms. In this study, we analyzed the conditions for employing DNA vector-based RNAi in silkworm cell lines using long-hairpin RNA-expressing plasmid DNA," scientists in Tsukuba, Japan report.

"We found that NIAS-Bm-oyanagi2 was the most effective cell line for RNAi. Expression of long-hairpin RNA containing an approximately 500 base-pair stem region suppressed expression of a reporter target gene by more than 99% in this cell line. Furthermore, the loop sequence of hairpin RNA was not as important to RNAi efficiency as previously observed in Drosophila...
