Project description:We performed H3K9me2-based ChIP-seq to identify regions of the Drosophila genome that are H3K9me2-depleted due to transgenic neuronal expression of human mutant tau. Examination of H3K9me2 histone methylation in 10 day old control and tau transgenic Drosophila heads.
Project description:We made RNA-Seq libraries of Heliconius melpomene heads, antennae, legs and mouth parts to identify genes upregulated in heads. We explored the expression patterns of a gene family that functions in visual pigment chromophore transport in Drosophila to identify a non-orthologous gene that has a similar function.
Project description:We investigated sleep deficits in Cyfip mutant Drosophila flies, a model for intellectual disabilities/neurodevelopmental disorders. RNA-seq was performed on heads at the circadian time point ZT16, i.e., during the night when wild-type flies are asleep.
Project description:Gene annoation and determination of gene expression levels in Drosophila virilis and Drosophila yakuba by deep sequencing. Total RNA-seq data from heads of 2-5 day old mated D virilis and D yakuba females, 1 sample from each species.
Project description:To evoke further attention to the potential hazard of increasingly accumulative blue light exposure, we construct a series of in vivo Drosophila models employed for multi-omics analyses. This project includes the RNA-seq data of w1118 male adult heads.
Project description:Microarray data obtained from control, cbtRNAi (cabut RNAi), and cbtOE (cabut overexpression) flies. From each strain, fly heads at two different time points during the day–night cycle (ZT3 and ZT153) were collected. Fly heads were collected and RNA was extracted. RNA was then used to prepare a probe that was hybridized to Drosophila 2.0 gene expression arrays (Affymetrix).
Project description:Purpose: Validation of Drosophila A-to-I editing sites Methods: We collected heads of 5 day old male dAdar-/- mutant (y, Adar5G1, w)26 and wild type (w1118) flies. Poly(A)+ RNA was used to prepare RNA-seq libraries which were subsequently sequenced single-end by an Illumina GAII Results:We builded a framework to identify RNA editing events using RNA-seq data alone in Drosophila. To validate whether the identified A-to-G sites were bona fide A-to-I editing events, we performed RNA-seq for the D.melanogaster wild-type strain (w1118) and for the Adar5G1 null mutant that eliminates RNA editing. We found that our method achieved high accuracy; 98.2% of all A-to-G sites showed only adenosine in the Adar5G1 sample Conclusions: We anticipate that our method will be very effective in the future to identify RNA editing events in different species. mRNA profiles of heads of 5 day old male dAdar-/- mutant (y, Adar5G1, w)26 and wild type (w1118) flies
Project description:Transcriptomic profiling using Drosophila heads reveals early gene expression responses to transient paraquat exposure. We performed RNAseq profiling of heads from the wild type (WT) Drosophila strain, Canton S (males only), that were fed either 2.5% sucrose (control) or 5 mM PQ in 2.5% sucrose for 12 h.
