  • Title: Changes in mouse liver and chicken embryo yolk sac membrane soluble proteins due to an organophosphorous insecticide (OPI) diazinon linked to several noncholinergic OPI effects in mice and chicken embryos.

    Journal: Pestic Biochem Physiol; 2014 Nov; 116():74-82. PubMed ID: 25454523.
    Abstract:
    The objective of this study was to identify proteins in mouse livers and chicken embryo yolk sac membranes whose quantities were altered by an organophosphorous insecticide (OPI) treatment and which might be linked, based on their functionality, to the recognized noncholinergic effects of OPI. Mice and fertile chicken eggs were treated with an OPI representative diazinon. The quantitative changes in mouse liver and chicken embryo yolk sac membrane soluble proteins caused by diazinon were determined by two-dimensional electrophoresis. Proteins whose quantity was affected by diazinon were identified by the mass spectrometry. In mouse livers, the altered levels of several enzymes of glucose metabolism were considered with regards to amelioration of hyperglycemia due to diazinon; the reduced levels of 3-hydroxyanthranilate 3,4-dioxygenase to the changes in the l-tryptophan to NAD metabolism caused by pyrimidinyl and crotonamide OPI; the reduced levels of catalase, peroxiredoxin and superoxide dismutase to OPI-increased lipid and/or kynurenine oxidation, the latter effect resulting also in increased urinary excretion of xanthurenic and kynurenic acids; and an increase in glutathione S-methyltransferase to OPI detoxification. In chicken embryo yolk sac membranes, the reduced availability of procollagen-proline dioxygenase may be the factor in micromelia caused by OPI in chicken embryos.
