Project description:We constructed three RNA libraries from embryos at 0-1, 2-4 and 5-8 post-oviposition (hpo) of Bactrocera dorsalis for deep sequencing. Using an Illumina HiSeq 2500 platform, we mapped more than 83, 85 and 98 million sequence reads from 0-1, 2-4 and 5-8 hour embryos respectively, and identified a total of 13,489 unigenes. 1683, 3201 and 3134 unigenes showed differential expression between the 0-1 and 2-4 hour embryos, the 0-1 and 5-8 hour embryos, and the 2-4 and 5-8 hour embryos respectively.

Project description:To identify Aub function in mRNA regulation in the Drosophila embryo, we have performed mass spectrometry analysis of Aub interactors, following immunoprecipitation of GFP-Aub in 0-2 hour-embryos. Immunoprecipitation of GFP alone was used as negative control. Because Aub accumulates at high levels in the germ plasm, GFP-Aub immunoprecipitation was also performed in oskar mutant embryos that do not assemble the germ plasm. Proteins coprecipitating with GFP-Aub were similar in wild-type and oskar mutant embryos. Translation factors were enriched among proteins coprecipitating with Aub.

Project description:The mosquito Ae. aegypti is responsible for the transmission of many diseases including yellow fever and Dengue fever. This species exhibits many behaviors that are under diel and circadian control. However, there has been little reporting on gene expression rhythmicity. To study how gene expression is globally regulated by diel and circadian mechanisms, we have undertaken a DNA microarray analysis of Ae. aegypti head and bodies under 12:12 light:dark cycle (LD) and constant dark (DD, free-running) conditions. Zeitgeber Time (ZT) with ZT12 defined as the initiation of the one hour dusk period under the light:dark cycle, and ZT0 defined as beginning of the one hour dawn period. Circadian Time (CT) with CT0 defined as subjective dawn, inferred from ZT0 of the previous light:dark cycle.

Project description:Background. Aedes aegypti is arguably the most studied of all mosquito species in the laboratory and is the primary vector of both Dengue and Yellow Fever flaviviruses in the field. A large number of transcriptional studies have been made in the species and these usually report transcript quantities observed at a certain age or stage of development. However, circadian oscillation is an important characteristic of gene expression in many animals and plants, modulating both their physiology and behavior. Circadian gene expression in mosquito species has been previously reported but for only a few genes directly involved in the function of the molecular clock. Results. Herein we analyze the transcription profiles of 21,494 messenger RNAs using an Ae. aegypti Agilent® microarray. Transcripts were quantified in adult female heads at 24 hours and then again at 72 hours and eight subsequent time points spaced four hours apart. We document circadian rhythms in multiple molecular pathways essential for growth, development, immune response, detoxification/pesticide resistance. Circadian rhythms were also noted in ribosomal protein genes used for normalization in reverse transcribed PCR (RT-PCR) to determine transcript abundance. We report pervasive oscillations and intricate synchronization patterns relevant to all known biological pathways. Conclusion. These results argue strongly that transcriptional analyses either need to be made over time periods rather than confining analyses to a single time point or development stage or exceptional care needs to be made to synchronize all mosquitoes to be analyzed and compared among treatment groups. 12 samples representing 48h timeline sampled every 4h. Each chip has one channel taken by sample at ZG24h and the other by ZG72h, ZG76h and so on. Each time point has two independent replicates from two independent pools of mosquitoes sampled on the same calendar day. These time series are concatenated to form one continuous 48h time series for each gene. The circadian expression analysis presented in the associated paper encompasses a test timeframe of 72 – 92 hour (Cy3-labeled).

Project description:BRAT-associated mRNAs and PUM-associated mRNAs were identified in early Drosophila embryos by RNA co-immunoprecipitation of the endogenous proteins using synthetic antibodies, followed by microarray analysis (RIP-Chip). Nine RNA co-immunoprecipitations were performed. This includes 3 biological replicates each of 1) anti-BRAT RNA co-immunoprecipitations from wild-type 0-3 hour embryos, 2) anti-PUM RNA co-immunoprecipitations from wild-type 0-3 hour embryos, and 3) control antibody RNA co-immunoprecipitations from wild-type 0-3 hour embryos. BRAT samples and PUM samples were each normalized separately with the control samples, for a total of 12 processed samples (3 BRAT with 3 control normalized together, and 3 PUM with 3 control normalized together) from the 9 RNA co-immunoprecipitations.

Project description:High-throughput sequencing of Drosophila pseudoobscura and Drosophila simulans small RNAs. ~18-26nt RNAs were isolated from total RNA using PAGE, ligation to adapters requires 5' monophosphate and 3' OH. Small RNAs were cloned from Drosophila pseudoobscura (heads and pooled 0-12 and 12-24 hour embryos) and Drosophila simulans (pooled 0-12 and 12-24 hour embryos). Sequencing was performed using the Illumina 1G platform. Following removal of 3' linker sequences, the clipped sequences longer than 18 nt were kept.
