ABSTRACT: GENOTYPIC CHARACTERIZATION OF Escherichia coli PRODUCER OF EXTENDED SPECTRUM BETALACTAMASES ISOLATED FROM CARCASSES OF CONVENTIONALLY PRODUCTION CHICKEN and PRODUCTION CHICKEN CERTIFIED WITH RESTRICTED USE OF ANTIMICROBIALS
Project description:The transcriptome of larval carcasses from both wildtype and Nxt1 trans-heterozygotes were assessed by RNA-Seq. A total of 1821 genes were down-regulated and 1339 genes were up-regulated. Down-regulated genes had a higher total intron length and had more introns, while up-regulated genes had a lower total intron length and less introns when compared to the non-differentially expressed genes. The majority of down-regulated genes were involved in the production of circular RNAs (circRNAS). We further investigated circRNA expression in larval carcasses from both wildtype and Nxt1 trans-heterozygotes by sequencing total RNA after RNAseR treatment. RNAseR digests linear RNA and thus enriches for circRNAs. Mock samples without RNAseR treatment were also sequenced. We found that circRNA products of Nxt1-responsive genes are reduced in Nxt1 mutants, although the nascent transcripts of these genes are produced at normal levels.
Project description:We sequenced dissected ovaries and testes (with reproductive tracts) as well as female and male carcasses in two species of Drosophila in order to validate gene predictions from the ModENCODE project. Comparison of dissected reproductive tracts and remaining carcasses between D. simulans and D. pseudoobscura

Project description:We used larval carcasses of both wildtype and Nxt1 trans-heterozygotes for RNA paired-end sequencing and obtained a read depth between 21M to 32M reads across all samples. A total of 1821 genes were down-regulated and 1339 genes were up-regulated. A python script extracting intron data of genes from the FlyMine database identified a trend where down-regulated genes had a higher total intron length and had more introns. Up-regulated genes had a lower total intron length and less introns when compared to the non-differentially expressed genes. Furthermore, down-regulated genes showed that the majority of genes are involved in the production of circular RNAs
Project description:We performed CAGE-Seq on dissected ovaries and testes as well as female and male carcasses of two species of Drosophila (D. melanogaster and D. pseudoobscura). These data are used to map transcription start sites. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf For both species, D. melanogaster and D. pseudoobscura, CAGE-Seq was performed on dissected gonads (with reproductive tracts) and remaining carcasses from wild-type adults, using Illumina GAIIx (SRA Study SRP001602, Bioproject PRJNA36315). There are eight samples. Only Drosophila melanogaster testis samples were performed in biological duplicate. See Chen ZX et al. Genome Res 2014, 24(7):1209-23.
