Project description:H3K27me3 profiles using Cleavage under targets and Release using nuclease (Cut&Run) in control and KD Drosophila melanogaster ovaries. We examined the impact on chromatin profiles in Drosophila melanogaster ovaries in which the lid, the Sin3a, the Snr1 or the mod(mdg4) gene have been selectively knocked down by tissue-specific shRNA expression. We additionally explored H3K27me3 and H3K9me3 in control and dhd mutant ovaries either carrying or not a transgene.
Project description:Comparison of small RNA fractions derived from piRNA clusters and transposon sequences in control and Su(var)3-7 null mutant. Small RNA profile of 3-day old control and Su(var)3-7 mutant ovaries were generated by high-throughput sequencing on Illumina HiSeq 2000
Project description:We report the m6dA modification on the Drosophila genome. We collected ovary genomic DNA from 2-day wild-type and DMAD mutant files and performed DNA-immunoprecipitation(DNA-IP)experiments using anti-m6dA antibody. The generated DNA library was subjected to a high-throughput deep sequencing analysis. In this assay, the IgG-immunoprecipited DNA from the same amount of wild-type ovaries was used as the control, and the high-throughput sequencing resulted in a range of approximately 3 to 4.6 million reads. In sum, we identified 50 and 195 peaks from wild-type and DMAD mutant samples. Importantly, m6dA is mainly utilized to modify the transposon sequence on the chromosomes.
Project description:The present study is the first study to identify the involvement of circRNAs in the ovary activation and oviposition regulation processes in honey-bee queens.CircRNAs expresion profiles were examined in ovaries of virgin queens, egg-laying queens, egg-laying inhibited queens and egg-laying recovery queens.

Examination of m6dA modifications in Genomic DNA of WT and DMAD mutant ovary.
Project description:The objective of this study was to understand the gene expression changes during granulosa cell tumor development in Smad1/5/8 mutant ovaries. Keywords: Microarray analysis, gene expression
Project description:Comparison of Foxl2-null ovaries to wildtype ovaries, ovaries lacking Wnt4 or Kit, or testes, throughout mouse development. The goal of this study was to identify early Foxl2 target genes as well as other ovarian, anti-testis genes that may act independently of Foxl2. Keywords: disease state analysis; genetic modification; developmental study
Project description:This series compares gene expression between germ line stem cells (GSCs) purified either from bam mutant or Dpp-overexpressing ovaries, with gene expression in Kc cells Keywords: bam mutant, Dpp overexpression
