Zebrafish gonadal transcriptome analysis in response to heat

ABSTRACT: High temperature can induce masculinization in many fish species including zebrafish (Ospina-Alvarez & Piferrer PLoS One 3:e2837). Juvenile zebrafish exposed to high temperature during gonad differentiation period will result in male bias adult sex ratio. This experiment compared the zebrafish gonadal transcriptome between fishes that were exposed to high (36 oC) and control (28 oC) temperatures. Gene expression analysis using microarray were performed at juvenile (37 dpf) and adult (90 dpf) stages.

Transcriptome comparative analysis of heat-induced domesticated zebrafish during gonadal differentiation

Project description:The influence of environmental factors, especially temperature, on sex ratio is of great significance to elucidate the mechanism of sex determination. However, the molecular mechanisms by which temperature affects sex determination remains unclear, although a few candidate genes have been found to play a role in the process. In this study, we conducted transcriptome analysis of the effects induced by high temperature on zebrafish during gonad differentiation period. 1171, 1022 and 2921 differentially expressed genes (DEGs) between high temperature and normal temperature were identified at 35, 45 and 60 days post-fertilization (dpf) respectively, revealing that DNA methyltransferases (DNMTs) and heat shock proteins (HSPs) were involved in the heat-exposed sex reversal. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway that were enriched in individuals after heat treatment included Fanconi anemia pathway, cell cycle, oocyte meiosis and homologous recombination. These results provide insights into the network of genes involved in heat-induced masculinization, and improve our understanding the molecular mechanisms of vertebrate sex determination.

RaynaNolen_2024_PFOS_Zebrafish_GEMs

Project description:Condition specific zebrafish metabolic models generated using the COBRA MetaboTools framework. The Wang et al., (2021) zebrafish genome-scale metabolic model (GEM) was constrained with experimental data from 5 days post fertilized (dpf) zebrafish to generate a 'base-model'. In turn this 5 dpf zebrafish base-model was constrained with experimental (transcriptomics and metabolomics) data from 5 dpf zebrafish exposed to the environmental pollutant perfluorooctane sulfonate (PFOS), at three levels - Low (0.06 uM), Medium (0.6 uM), and High (2 uM) PFOS. The MetaboTools framework was used to construct three condition-sepcific models: Low, Medium, and High PFOS. Key simulation predictions of effects on the carnitine shuttle and lipid metabolism were confirmed in wild-caught fish and dolphins (stranded animals) sampled from the northern Gulf of Mexico - published in Nolen et al., (2024) https://doi.org/10.1016/j.cbpc.2023.109817

Transcriptomic analysis reveals the involvement of canonical Wnt signaling in zebrafish gonad differentiation

Project description:Zebrafish males undergo a juvenile ovary to testis type gonadal transformation process. To understand how juvenile ovary-to-testis transformation in zebrafish is genetically regulated, we compared the transcriptomes of juvenile ovary (JO) and juvenile ovotestis (JOT) samples at 35 dpf using the Gonad Uniclone Microarray v1 (ArrayExpress ID: A-MEXP-838). We also analyzed the transcriptomes of the 32 dpf JO, 32 dpf JOT, 34 dpf JOT, and 36 dpf JOT gonads using the slightly modified Gonad Uniclone Microarray v2 and together with the 35 dpf JO and 35 dpf JOT samples, compared the JO samples against the JOT samples to identify genes that could be potentially involved in the gonad transformation process.

RNA-seq of wild-type zebrafish embryos developmentally exposed to three addictive drugs

Project description:RNA-seq of wild-type Tüpfel long fin (TLF) zebrafish embryos developmentally exposed to three addictive drugs - 5 µM nicotine, 1.14 µM oxycodone and 5 µM amphetamine. Each of the 24 samples (6 samples per drug, plus 6 control samples) represents RNA from a pool of seven 5 dpf zebrafish embryos, exposed to the drug between 1 dpf and 5 dpf.

Insights into the modes of action of tritium on zebrafish, Danio rerio, early-life stages, using proteomic analyses

Project description:Tritium is an ubiquist radionuclide which can be found in the environment due to natural and anthropogenic activities, particularly in aquatic ecosystems. In this context, tritium effects on aquatic species such as fish have to be characterized. HTO (tritiated water) effects were therefore investigated in zebrafish, Danio rerio, a common model in toxicology and ecotoxicology with a fully sequenced genome. Experiments were conducted on early life stages. Larvae were exposed to 0.4 and 4 mGy/h of HTO until 10 days post fertilization. Tritium internalization was quantified and effects were investigated using a proteomic analysis. The global analysis of the proteome was performed after protein extraction at 7 and 10 dpf on zebrafish eggs exposed from 3 hpf to 10 dpf.

Characterization of biological pathways regulating acute cold resistance of zebrafish - experiment 1

Project description:Low temperature stress represents a major threat to the lives of both farmed and wild fish species. However, biological pathways determining the development of cold resistance in fish remain largely unknown. Zebrafish larvae at 96 hpf were exposed to lethal cold stress (10 oC) for different time periods to evaluate the adverse effects at organism, tissue and cell levels. In this study, time series RNA sequencing (RNA-seq) experiments were performed to delineate transcriptomic landscape of zebrafish larvae under cold stress and during the subsequent rewarming phase.

Effect of 17 M-NM-2-estradiol on developing zebrafish embryos

Project description:Estrogen signaling is important for vertebrate embryonic development. Here we have used zebrafish (Danio rerio) as a vertebrate model to identify estrogen regulated genes during the first 4 days of development. Zebrafish embryos were exposed to 1 M-BM-5M 17M-NM-2-estradiol from 3 hours post fertilization to 4 days post fertilization, harvested daily and subjected to RNA extraction for transcriptome analysis using microarrays. Estrogen responsive genes were analyzed with hierarchical clustering followed by gene function and tissue expression analysis. Markedly distinct sets of genes were up and down-regulated by estrogen treatment at different time points. Among these genes, only the well-known estrogenic marker vtg1 was co-regulated at all time points. Despite this, the biological functional categories targeted by estrogen were similar throughout zebrafish development. Estrogen responsive genes were enriched mainly in the liver, pancreas and brain. In conclusion, our data shows that in zebrafish distinct cohorts of E2 responsive genes are expressed in a tissue specific manner at different developmental stages. However, the biological pathways that are affected are conserved. 30 embryos were pooled as one sample and exposed to 1 M-NM-<M E2 or vehicle (0.1% DMSO) at approximately 3 hours post fertilization (hpf). At different time points, 1 dpf (24 hpf), 2 dpf (48 hpf), 3 dpf (72 hpf) and 4 dpf (104 hpf), embryos were collected for total RNA extractions. Time points 1 and 2 dpf were performed in biological triplicates of independent pools of RNA while time points 3 and 4 dpf were performed in quadruplicates.

Proteomic changes in liver of Channa striatus in response to high temperature stress

Project description:Climate change and resulting global warming are challenging environmental problems. Understanding the thermal adaptation mechanisms and survival strategies are of paramount importance. Fish has served as excellent animal model for understanding many biological processes. The present study was undertaken to investigate the proteomic changes in liver of murrel Channa striatus exposed to high temperature stress. Fishes were exposed to 36 °C for 4 days and liver proteome changes were analyzed using gel- based proteomics i.e. 2D gel electrophoresis, MALDI-TOF-MS and validation by transcript analysis. The study showed, besides others, up regulation of two sets of proteins, the antioxidant enzymes SOD, ferritin, GST and chaperones HSP60, PDI which was validated by transcript analysis. Further, gene expression analysis was also carried out in the fishes exposed to thermal stress for longer duration (30 days, in the laboratory and beyond, taking Channa collected from a hot spring runoff at a water temperature 36-38 °C); hsp60, sod and gst were found to continue to remain up regulated at 11, 8 and 3 folds, respectively in the hot spring runoff fish. Thus the study showed that SOD, GST and HSP60 play important role in thermal adaptation and survival under chronic heat stress.
