The regulation of transcriptome responses in zebrafish embryo exposure to triadimefon
Abstract
The residue of triadimefon (TDF) (a pesticide) has become the pollutant in water due to its intensive use in agriculture and medicine, and its stability in water leaching from soil and vegetation. In this study, RNA-seq, a high-throughput method was performed, to analyze the global expression of differential expressed genes (DEGs) in zebrafish embryos treated with TDF (10 μg/mL) from fertilization to 72 h post-fertilization (hpf) as compared with that in the control group (without TDF treatment). Two cDNA libraries were generated from treated and non-treated embryos, respectively. With the 79.4% and 78.8% of reads mapped to the reference, it was observed that many differential genes were expressed between the two libraries. The most 20 differentially expressed up-regulated or down-regulated genes were involving in the signaling transduction, the activation of many genes related to cytochrome P450 enzymes, and molecular metabolism. Validation of seven genes expression confirmed RNA-seq results. The transcriptome sequences were further subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis and showed diverse biological functions and metabolic pathways. The data from this study contributed to a...Continue Reading
