    ..Our results suggested the importance of heat shock response in facilitating the correction of G-T mismatch in developing zebrafish even under Cd exposure. ..

    ..The weaker response of MSH gene activities to Hg(2+) correlated with the lower oxidative stress-inducing potential of Hg(2+) . Hence, Hg(2+) targets mismatch sensing capacity at protein function rather than at transcription level. ..

    ..Our results identified the participation of Vg1-like factors in NER in developing zebrafish, and these factors may function at post-incison steps of NER. ..

    ..Our results revealed the inhibition of Cd on MSH6 expression at both mRNA and protein levels and this mechanism may play a role in Cd genotoxicity. ..
  5. Lai Y, Hsieh F, Hsu T. Affinity isolation and mass spectral analysis of 1,10-phenanthroline (OP)-stimulated UV-damaged-DNA binding proteins expressed in zebrafish (Danio rerio) embryos. Fish Physiol Biochem. 2012;38:1117-1129 pubmed publisher
    ..The OP-stimulated fraction produced a much stronger UV-dependent DNA incision activity in the presence than in the absence of OP, suggesting the association of these factors with DNA damage repair under metal-deficient conditions. ..

    ..Our results showed the potential of Hg2+ at environmental relevant levels to disturb NER in zebrafish embryos by targeting primarily at the stage of DNA incision/excision. ..
