Target Effects

RNAi-mediated gene knockdown in Drosophila melanogaster is a powerful method to analyze loss-of-function phenotypes both in cell culture and in vivo. However, it has also become clear that false positives caused by off-target effects are prevalent, requiring careful validation of RNAi-induced phenotypes. The most rigorous proof that an RNAi-induced phenotype is due to loss of its intended target is to rescue the phenotype by a transgene impervious to RNAi. For large-scale validations in the mouse and Caenorhabditis elegans, this has been accomplished by using bacterial artificial chromosomes (BACs) of related species. However, in Drosophila, this approach is not feasible because transformation of large BACs is inefficient. We have therefore developed a general RNAi rescue approach for Drosophila that employs Cre/loxP-mediated recombination to rapidly retrofit existing fosmid clones into rescue constructs. Retrofitted fosmid clones carry a selection marker and a phiC31 attB site, which facilitates the production of transgenic animals. Here, we describe our approach and demonstrate proof-of-principle experiments showing that D. pseudoobscura fosmids can successfully rescue RNAi-induced phenotypes in D. melanogaster, both in cell culture and in vivo. Altogether, the tools and method that we have developed provide a gold standard for validation of Drosophila RNAi experiments.

ABSTRACT The construction of a set of transmissible gastroenteritis coronavirus (TGEV)-derived replicons as bacterial artificial chromosomes is reported. These replicons were generated by sequential deletion of nonessential genes for virus replication, using a modified TGEV full-length cDNA clone containing unique restriction sites between each pair of consecutive genes. Efficient activity of TGEV replicons was associated with the presence of the nucleoprotein provided either in cis or in trans. TGEV replicons were functional in several cell lines, including the human cell line 293T, in which no or very low cytopathic effect was observed, and expressed high amounts of heterologous protein.
