Huan jing ke xue= Huanjing kexue / [bian ji, Zhongguo ke xue yuan huan jing ke xue wei yuan hui "Huan jing ke xue" bian ji wei yuan hui.] 2009 Nov0hpf zebrafish embryos were exposed to 50 microg/L pentachlorophenol(PCP) for 8h in vitro. Total RNA sample was extracted then and hybridized with Affymetrix Zebrafish Genome Array representing approximately 14 900 transcripts. A total of 1 149 transcripts was significantly up-regulated while 501 transcripts were down-regulated. Bioinformatic tools were used for further analysis. The result indicated that genes with significant expression changes were related to molecular functions including antioxidant activity, signal transducer activity, translation regulator activity, transcription regulator activity, et al. Genes regulated by BMP signals, FGF signals, and Nodal signals including smad2, smad5, bmp4, bmp7, flh, n-ras may involve in the developmental toxicity of PCP, with Signal log ratios of 4.6, 2.1, 1.6, 1.0, 1, 1.3, 1.0, respectively. This investigation may provide new biomarkers to further study of the developmental toxicity of PCP.
