These three mRNAs were chosen based on their diverse cellular functions and length of the double-stranded 3�� UTR, which range from 517 to 1,423 nucleotides (nts). RNA was isolated from three independent biological replicates of wild-type and adr-1(?) adult worms. After reverse transcription, PCR amplification, and Sanger sequencing, editing efficiency was quantitatively measured using the Bio-Edit program. Technical replicates of the editing assay suggest that?editing at each site can be determined with?[https://en.wikipedia.org/wiki/Ceftiofur Ceftiofur] data on the accuracy of measuring editing efficiency by Sanger sequencing ( Eggington et?al., 2011). Of the 50 edited adenosines, we observed statistically significant differences in editing levels between wild-type and adr-1(?) worms at 22 individual sites ( Figure?1A). The bulk of the statistically significant sites (91%) had decreased editing, ranging from 3%�C35%, in the absence of adr-1. To demonstrate that these sites are directly regulated by ADR-1, a 3�� FLAG-tagged genomic version of adr-1 was reintroduced to adr-1(?) worms by microinjection. Importantly, this transgenic worm rescues a known adr-1 dependent effect on neuronal protein expression ( Hundley et?al., 2008), [http://www.selleckchem.com/products/ldk378.html Ceritinib chemical structure] indicating that the transgene expresses functional ADR-1 protein ( Figure?S1B). As the transgenic worms express FLAG-ADR-1 from an extrachromosomal array that is transmitted to progeny at a high frequency, but not 100%, a neuronal GFP marker was coinjected and flow cytometry was used to purify worms containing the ADR-1 transgene. In addition, to reduce effects of developmental timing on editing efficiency all worms were also sorted by size to obtain young adults. The quantitative editing assay showed that FLAG-ADR-1 significantly restored editing to 15 of the 22 editing sites altered in adr-1(?) worms ( Figure?1B). It is important to note that editing changes in the FLAG-ADR-1 worms are not a general phenomenon, because editing sites that are not affected by loss of adr-1 are not altered by the transgene ( Figure?S1C). The 15 ADR-1-regulated sites include both adenosines that have increased and decreased editing in the absence of adr-1. Together, these data indicate [http://www.selleckchem.com/Caspase.html Caspase inhibitor in vivo] that ADR-1 alters editing of multiple transcripts, but the effects vary depending upon the individual adenosines examined. Because the effects of adr-1 on editing are site specific, we hypothesized that ADR-1 is capable of regulating editing by utilizing two double-stranded RNA binding domains (dsRBDs) to bind to potential editing substrates and alter accessibility of?ADR-2 to particular nucleotides. To determine if ADR-1 could bind ADR-2 editing targets in?vivo, we developed an RNA immunoprecipitation (RIP) assay for ADR-1. Because a previously generated polyclonal antibody to ADR-1 was incapable of immunoprecipitating ADR-1 efficiently, the 3�� FLAG-tagged ADR-1 transgenic worm was utilized.
