(Submitter supplied) In this study, we performed microarray-based expression profiling on liver of zebrafish exposed to 60 mg/L (192?M) arsenic [As(V)] for 8-96 h, to identify global transcriptional programs and biological networks involved in arsenic-induced adaptive responses in vivo. We identified temporal differentially-expressed gene sets which we have grouped into early, late and all-time arsenic-responsive gene sets. more...

(Submitter supplied) We performed microarray experiment on zebrafish exposed to estrogen (17β-estradiol; a classified carcinogen) and an anti-estrogen (ICI 182,780). Our transcriptome analysis captured multiple estrogen-responsive genes and signaling pathways that increased cell proliferation, promoted DNA damage and genome instability, and decreased tumor suppressing effects, suggesting a common mechanism for estrogen-induced carcinogenesis. more...

(Submitter supplied) In the present study, we employed the RNA sequencing platform to examine the molecular response of zebrafish liver to arsenic exposure and carry out detailed transcriptomic analyses for further understanding of molecular toxicity. We found that several important biological processes were perturbed by arsenic exposure, including oxidation reduction, translation, iron ion transport, cell redox and homeostasis, as well as related pathways in metabolism and diseases. more...

(Submitter supplied) To investigate the effects of glucocorticoids on the gene expression profiles in zebrafish, we performed a microarray-based transcriptomic study using larvae exposed to three representative glucocoriticoids at environmentally relevant high and low concentrations. Transcriptiomic profiel of developing zebrafish larvae exposed to dexamethasone, prednisolone or triamcinolone at 50 pM to 50 nM from 3 hours post-fertilisation to 5 days post-fertilisation were analyzed using G2519F Agilent Zebrafish Whole Genome Oligo Microarray Ver3.0, 4x44K.

(Submitter supplied) A convergence of technological breakthroughs in the past decade has facilitated the development of rapid screening tools for biomarkers of toxicant exposure and effect. Platforms using the whole adult organism to evaluate the genome-wide response to toxicants are especially attractive. Recent work demonstrates the feasibility of this approach in vertebrates using the experimentally robust zebrafish model. more...

(Submitter supplied) Here, we certified zebrafish to be a suitable model for the compensatory growth study. After a 3-weeks fasting, recovered for 3 days, 10 days and 15 days were chose as the initial, middle and late sampling sites for compensatory growth analysis, and liver samples of each time point were chose for the microarray analysis.At the same time, zebrafish fed ad libitum, as well as fasting for 3 weeks were also added to the microarray research.

(Submitter supplied) Background: Exposure to dichlorvos (DDVP), an organophosphorus pesticide, is known to result in neurotoxicity as well as other metabolic perturbations. However, the molecular causes of DDVP toxicity are poorly understood, especially in cells other than neurons and muscle cells. To obtain a better understanding of the process of non-neuronal DDVP toxicity, we exposed zebrafish to different concentrations of DDVP, and investigated the resulting changes in liver histology and gene transcription. more...

(Submitter supplied) Liver plays a key role during the stress adaptation process. Therefore to understand the molecular adjustments that occur in fish to counter the stress during transport, transcriptional changes in zebrafish liver were analyzed with a 4x44K oligo array using total RNA extracted from fish prior to transport (basal), immediately after packing (0 h) and during the mock transport (48 and 72 h).

(Submitter supplied) Early life stages are generally most sensitive to toxic effects. Our knowledge on the action of man-made chemicals on the developing vertebrate embryo is, however, rather limited. We exposed zebrafish embryos to 11 of environmental toxicants and measured the changes in gene expression profiles by microarray. Our results demonstrate that the genome of the zebrafish embryo responds to toxicant exposure in a highly sensitive and specific manner. more...
