A modERN Resource: Identification of Drosophila Transcription Factor candidate target genes using RNAi

Project description:Transcription factors (TFs) play a key role in development and in cellular responses to the environment by activating or repressing the transcription of target genes in precise spatial and temporal patterns. In order to develop a catalog of target genes of D. melanogaster transcription factors, the modERN consortium systematically knocked down expression of transcription factors (TFs) using RNAi in whole embryos followed by RNA-seq. We generated data for 45 TFs which have 18 different DNA-binding domains and are expressed in 15 of the 16 organ systems. The range of inactivation of the targeted TFs by RNAi ranged from log2fold change -3.52 to +0.49. The TFs also showed remarkable heterogeneity in the numbers of candidate target genes identified, with some generating thousands of candidates and others only tens. We present detailed analysis from six experiments, including those for four TFs that have been the focus of previous functional studies (ERR, sens, su(Hw) and zfh2) and two previously uncharacterized TFs (sens-2 and CG32006), as well as short vignettes from selected additional experiments to illustrate the utility of this resource. Transcription Factor and target gene expression patterns can be found here: https://insitu.fruitfly.org. These studies provide data that facilitate scientific inquiries into the functions of individual TFs in key developmental, metabolic, defensive, and homeostatic regulatory pathways, as well as provide a broader perspective on how individual TFs work together in local networks during embryogenesis.

A genome-scale shRNA resource for transgenic RNAi in Drosophila

Project description:Existing transgenic RNAi resources in Drosophila utilize the expression of long double stranded hairpin RNAs and are powerful tools for the identification and characterization of genes involved in various processes. However, they are ineffective to knockdown genes during oogenesis, an important model system for the study of numerous fundamental questions in biology. Here, we show that short hairpin RNAs (shRNAs), modeled on an endogenous microRNA, are extremely effective at silencing gene expression during oogenesis. We also describe our progress towards building a genome-wide shRNA resource.

Selection of well-tolerated GalNAc-conjugated siRNAs by screening for RNAi-mediated off-target effects in rodent toxicity studies

Project description:Small interfering RNAs (siRNAs) conjugated to a trivalent N-acetylgalactosamine (GalNAc) ligand are being evaluated in investigational clinical studies for a variety of indications. The typical development candidate selection process includes evaluation of the most active compounds for toxicity in rats at pharmacologically-exaggerated doses. The subset of GalNAc-siRNAs that show rat hepatotoxicity is not advanced to clinical development. Potential mechanisms of hepatotoxicity include toxicities associated with the intracellular accumulation of oligonucleotides and their metabolites, RNA interference (RNAi)-mediated hybridization-based off-target effects, and/or perturbation of endogenous RNAi pathways. Here we show that rodent hepatotoxicity observed at supratherapeutic exposures can be largely attributed to RNAi-mediated off-target effects, but not chemical modifications or the perturbation of RNAi pathways. Furthermore, these off-target effects can be mitigated by modulating seed-pairing using a thermally destabilizing chemical modification, which significantly improves the safety profile of a GalNAc-siRNA in rat and may minimize the occurrence of hepatotoxic siRNAs across species.
