Description
We used an improved INTACT (Isolation of Nuclei Tagged in A specific Cell Type) technique to isolate RNA from purified nuclei from different neuronal populations of the Drosophila brain. Using RNA-seq, we determined gene expression and A-to-I RNA editing levels at editing sites across nine distinct neuronal sub-populations and a pan-neuronal control. Overall design: We crossed UAS-unc84-2XGFP transgenic flies with 10 different GAL4 drivers (Dh44-GAL4, NPF-GAL4, NPFR-GAL4, Tdc2-GAL4, Crz-GALl4, TH-GAL4, Trh-GAL4, Fru-GAL4, OK107-GAL4, and elav-GAL4), immunoprecipitated tagged nuclei and extracted RNA. Three independent replicates of each each cross were performed to isolate RNA for RNA-sequencing.

Description
Purpose: To chart the human myometrial transcriptomes before and after the onset of labour. Methods: Tophat splice junction mapping of paired-end reads, HTSeq to generate counts, cufflinks to track transcripts, DESeq, edgeR and baySeq to detect differentially expressed genes and principal component analysis for clustering analyses. Results: We mapped on average 14 million paired-end reads per sample (counting each end individually) to the human genome (build hg19) and covered the expressed transcriptome about 13 times with a TopHat-HTSeq workflow. We performed a comparative analysis with an analogous microarray study (Mittal et al., 2010) and found some overlap between the RNA-seq and the microarray data. Conclusions: Our study is the first RNA-seq study of the human myometrium before and after the onset of labour. We show that while microarray and RNA-seq studies may complement each other, RNA-seq has a much greater resolution. Overall design: At term with and at term without labour human myometrial mRNA profiles were generated by deep sequencing, using Illumina GAIIx (five biological replicates each).
