Proteomics analysis of behavioral adaptation in zebrafish larvae

ABSTRACT: In this work we investigated how the brain proteome of the larval zebrafish is modified by behavioral adaptation to the environmental challenge of a water vortex. We monitored the behavior of larvae and observed that they behaviorally adapted to the presence of a water vortex. We obtained the larval zebrafish brain proteome by extracting brains from zebrafish larvae and analyzing them using and LFQ-based LC-MS/MS-approach. In total we identified 5929 proteins in the larval brain. Within this proteome, we identified 57 proteins that were significantly regulated following experience of the water vortex: 41 proteins were up regulated and 16 were down regulated. Of these, 29 proteins are known to have neuronal functions, 17 proteins are known to have other cellular functions, and 11 proteins are still uncharacterized.

Acrylamide acute neurotoxicity in adult zebrafish

Project description:Acute exposure to acrylamide (ACR), a type-2 alkene, may lead to a ataxia, skeletal muscles weakness and numbness of the extremities in exposed human and laboratory animals. Recently, a zebrafish model for ACR neurotoxicity mimicking most of the pathophysiological processes described in mammalian models, was generated in 8 days post-fertilization larvae. In order to better understand the predictive value of the zebrafish larvae model of acute ACR neurotoxicity, in the present manuscript the ACR acute neurotoxicity has been characterized in the brain of adult zebrafish, and the results compared with those obtained with the whole-larvae. Although qualitative and quantitative analysis of the data shows important differences in the ACR effects between the adult brain and the whole-larvae, the overall effects of ACR in adult zebrafish, including a significant decrease in locomotor activity, altered expression of transcriptional markers of proteins involved in synaptic vesicle cycle, presence of ACR-adducts on cysteine residues of some synaptic proteins, and changes in the profile of some neurotransmitter systems, are similar to those described in the larvae. Thus, these results support the suitability of the zebrafish ACR acute neurotoxicity recently developed in larvae for screening of molecules with therapeutic value to treat this toxic neuropathy.

Activating transcription factor 6 is necessary and sufficient for alcoholic fatty liver disease in zebrafish

Project description:ATF6 is a key regulator of the unfolded protein response. Through use of zebrafish and cultured cells we demonstrate that ATF6 drives fatty liver disease by interaction with fatty acid synthase (FASN). Total small RNA from livers of 5 dpf larval zebrafish were collected: 2 batches of Tg(fabp10:nls-mCherry) control larvae, 2 batches of ethanol-treated Tg(fabp10:nls-mCherry) larvae, and 1 batch of Tg(fabp10:nAtf6-cherry; cmlc2:GFP). Each batch was purified for preparation of high-throughput sequencing libraries.

Whole-genome expression data from purified larval Drosophila LNv pacemaker neurons

Project description:We generated whole genome expression profiles from a homogeneous population of purified pacemaker neurons (ventral Lateral Neurons, LNvs) from wild type and clock mutant Drosophila. The study identifes a group of genes whose expression is highly enriched in LNvs compared to other neurons; and a second group of genes rhythmically expressed in LNvs in a clock-dependent manner. Drosophila larval brains (L3 stage) were taken from a 12:12hr light entrainment regime and dissected at ZT-3 or ZT-15. Larvae contained either Pdf-Gal4:UAS-GFP transgenes or Pdf-RFP to label the 8 LNvs pacemaker neurons per brain, allowing purification by flow cytometry. Brains were dissociated and LNvs purified by FACS, followed by RNA amplification and hybridization on Affymetrix microarrays.

Mapping of Polycomb binding in Drosophila larval brain tissue using DamID

Project description:We made Polycomb (PC) and histone H3 lysine 27 trimethylation (H3K27me3) chromatin binding maps in central brain tissue from 3rd instar larvae, allowing us to make a direct comparison to our 4C data (http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE23166). Our results demonstrate that our PC and H3K27me3 maps are highly similar, and fit with previously identified hallmarks of PcG-bound chromatin, namely: PC and H3K27me3 co-occur in the genome as large contiguous domains that largely repress transcription of the underlying genes, which encode important regulators of development. Keywords: Genome binding/occupancy profiling by genome tiling array DamID experiments for Polycomb were performed in Drosophila larval brain tissue. Samples were hybridized to 380k NimbleGen arrays with 300 bp probe spacing.

Gene expression in mitotic tissues of Drosophila larvae without centrosomes or too many centrosomes

Project description:Centrosome defects are a common feature of many cancers. Surprisingly, flies can proceed through the majority of development without centrosomes or with amplified centrosomes in most of their cells. It is unclear whether this is because centrosome defects do not cause many problems in Drosophila cells, or because they can adapt to cope with any problems that arise. Indeed, centrosome loss and centrosome amplification predispose fly brain cells to form tumours. Here we assess how centrosome loss or centrosome amplification perturbs cell physiology by profiling the global transcriptome of Drosophila larval brains and imaginal discs that either lack centrosomes or have too many centrosomes. Mitotic tissues (brains and imaginal discs) were dissected from 3rd instar Drosophila larvae of mutants lacking centrosomes (DSas-4 and DSas-6), a strain with too many centrosomes (SakOE) and two different wild type strains (w67 and OregonR). We extracted RNA from three biological replicates per strain and used it for hybridisation to Affymetrix Drosophila Genome 2.0 arrays. Per biological sample, material dissected from ten larvae was pooled. Gene expression of the mutant strains was compared to both wild type controls.

Apis mellifera,Hemolymph,LC-MSMS

Project description:We characterized and compared hemolymph proteome of Royal Jelly bees (RJbs), a stock selected for increasing RJ output from Italian bees (ITbs) and ITbs across the larval and adult ages. Unprecedented depth of proteome was attained by identifying 3394 hemolymph proteins in both bee lines. The proteome supports the general function of hemolymph to drive development and immunity across different phases in both bees. However, age-specific proteome settings have adapted to prime the distinct physiology for larvae and adult bees. In larvae, proteome are thought to drive the temporal immunity, rapid organogenesis, and reorganization of larval structures. In adults, proteome play key roles to prompt tissues development and immune defense in NEBs, glands maturity in NBs and carbohydrate energy production in FBs. Comparing the proteome between the same aged larval and adult samples, RJbs and ITbs have tailored distinct hemolymph proteome programs to drive their physiology. Particularly, in day 4 larvae and NBs, a large number of highly abundant proteins enriched in protein synthesis and energy metabolism in RJbs relative to ITbs imply that RJb larvae and NBs have reprogrammed their proteome to initiate different developmental trajectory and high RJ secretion in response to the enhanced RJ production by selection. Our hitherto depth of proteome coverage gains novel sight on molecular details in driving hemolymph function and high RJ production by RJbs.

Next Generation Sequencing (NGS) of zebrafish larvae transcriptome by 2,2',4,4'-tetrabromodiphenyl ether (BDE47) treatment

Project description:Purpose: We report the application of NGS for profiling the impacts of BDE47 exposure on the transcriptome of zebrafish larvae. Methods: mRNA profiles of 6-day-old BDE47-treated and control zebrafish larvae were generated by deep sequencing using Illumina Hisq 2000 platform. The sequence reads that passed quality filters were analyzed at the transcript isoform level with TopHat followed by Cufflinks. Results: Compared BDE47 treatments with solvent control, 2235 transcripts were affected after 500 μg/l exposure, in which 1338 were up-regulated and 897 were down-regulated, and 552 transcripts were affected after 5 μg/l exposure, in which 155 were up-regulated and 397 were down-regulated. High concentration of BDE47 exposure resulted in more up-regulated genes. Conclusions: This study provides a framework for the application of high-throughput RNA sequencing towards characterization of the impacts of BDE47 on whole zebrafish larval transcriptome. Examination of zebrafish larvae transcriptomes with vehicle and 2 different concentrations of BDE47 treatments.
