Description
RNA expression was measured by RNA-seq in Drosophila ML-DmBG3-c2 cells depleted for proteins involved in sister chromatid cohesion, and in developing third instar wing discs with or withough brca2 gene mutations Overall design: RNA expression in depleted cells was compared to mock treated cells and RNA expression in wing discs from brca2 mutant Drosophila was compared to expression in wing discs without brca2 mutations This series includes mock RNAi treated samples re-used from GSE100547.

Description
Alternative splicing comprises a robust generator of mammalian transcriptome complexity. Splice site specification and activity are controlled by interactions of cis-acting determinants on a transcript with specific RNA binding proteins. A major subset of these interactions comprises interactions localized to the intronic U-rich polypyrimidine tract located immediately 5’ to the majority of splice acceptors. alphaCPs (also referred to as polyC-binding proteins (PCBPs) and hnRNP Es) comprise a subset of KH-domain proteins with high specificity and affinity for C-rich polypyrimidine motifs. Prior studies have revealed that binding of alphaCPs to C-rich motifs can modulate splicing and 3’ processing of the human alpha-globin mRNA transcript in the nucleus as well as stabilization of the halpha-globin mRNA in the cytoplasm. In the current report, we demonstrate that alphaCPs have a positive impact on the activity of splice acceptor sites in a defined subset of mammalian transcripts via binding to polypyrimidine tracts that are predominantly C-rich. These findings lead us to conclude that the alphaCPs play a global role in determining the splicing activity and levels of cassette exon inclusion within the mammalian transcriptome. Overall design: To test the impact of aCP proteins on alternative splicing, aCP proteins were knockdown from K562 cells by siRNA. Since aCP1 and aCP2 have redundent function, we therefore designed siRNAs capable of knockdown both isoform at the same time. 3 aCP1/2 combined knockdown and 3 control siRNA knockdown were performed in K562 cells. RNA-seq were then performed to identify alternative splicing pattern mediated by aCP proteins.

Description
To understand the function and regulation of the C. elegans heat shock factor (HSF-1) in larval development, we have used ChIP-seq to analyze the occupancy of HSF1 and RNA Pol II in L2 larvae and young adult (YA) animals grown at 20°C or upon heat shock at 34°C for 30 min. In addition, we have used RNA-seq to analyze the transcriptomes of wild type (N2), hsf-1(ok600) mutants and hsf-1(ok600); rmSi1[hsf-1::gfp] L2 larvae grown at 20°C and characterized the gene expression change by heat shock in wild type (N2) animals at L2 stage. Overall design: Experiment type: RNA-seq. Biological Source: strain: N2, OG576, AM1061; developmental dtage: L2 Larva. Experimental Factors: temperature: 20 degree celsius.

Description
Glyphosate-based herbicides are the major pesticides used worldwide. There is an intense debate on the estrogenic effects of their ingredients. We have compared the estrogenic effects of glyphosate (the active principle), polyethoxylated tallowamine (a co-formulant), and a commercial formulations containing different co-formulants to those of estradiol and bisphenol A in the MCF-7 human breast cancer cell line. The gene expression profiles were determined using the Affymetrix Human Transcriptome 2.0 Array.
