Abstract:
The present invention relates to a method for confirming the exposure on chrysene using a DNA fragment whose expression is increased or decreased specifically when it is exposed to chrysene. The method of the present invention is effective in determination of risk by chrysene and monitoring the chrysene exposure, so that it can be effectively used as a tool for examining the mechanism of chrysene induced toxicity.
Abstract:
PURPOSE: A biomarker for confirming phenanthrene exposure is provided to monitor and determine phenanthrene pollution and to find a toxicity mechanism. CONSTITUTION: A biomarker for confirming phenanthrene contains a gene of which an expression is increased or decreased due to exposure to phenanthrene. A DNA microarray chip for confirming phenanthrene exposure contains oligotide having an entire or partial gene sequence or its complementary oligonuecleotide. A method for detecting the biomarker for confirming phenanthrene exposure comprises: a step of isolating RNA from a test person's somatic cells as an experimental group and normal somatic cells as a control group; a step of synthesizing cDNA of the experimental group and control group and labeling with different fluorescences; a step of hybridizing the labeled cDNA on a microarray chip; a step of analyzing DNA microarray chip; and a step of comparing expression level between control group and experimental group.
Abstract:
PURPOSE: A biomarker for detecting exposure to polycyclic aromatic hydrocarbons(PAHs) is provided to usefully monitor and determine contamination of PAHs and figure toxicity mechanism caused by the PAHs. CONSTITUTION: A biomarker for detecting exposure to polycyclic aromatic hydrocarbon(PAHs) contains a gene of which expression is decreased or increased by the exposure of the PAHs. A DNA microarray chip for detecting the exposure to the PAHs comprises oligonucleotide including entire or partial biomarker gene sequence and its complementary oligonucleotide. A method for detecting the exposure of the PAHs using the biomarker comprises: a step of isolating RNA from sample-derived human somatic cells as an experimental group and normal somatic cells as a control group; a step of synthesizing RNA to cDNA and labeling the experimental group and control group with different colors; a step of hybridizing the cDNA on the DNA microarray chip; a step of analyzing the DNA microarray chip; and a step of comparing the expression level between the experimental group and control group.
