Abstract:
The present invention relates to a methylation biomarker specific to human exposure to toluene, one of volatile organic compounds, and a detection method using the same and, more specifically, to a toluene exposure-specific marker gene having a promoter region of a certain gene specifically methylated by the exposure to toluene, and a method for identifying human exposure to toluene using the marker gene. The methylation marker of the present invention can be useful for accurately and rapidly monitoring and determining toluene contamination in human specimens exposed to environment compared to a conventional method, and also used as a tool identifying mechanisms of toxic action caused by toluene by using the methylated promoter region of a reactive gene selected by DNA methylation microarray chips as a biomarker.
Abstract:
The present invention relates to microRNA for identifying xylene exposure in a human body, and a method for identifying xylene exposure using the same. More particularly, the present invention can be usefully used for monitoring and deciding pollution by xylene in a human sample exposed to environment by using the microRNA whereby an expression is specifically increased or decreased via xylene as a biomarker. Moreover, the present invention can also be used as a tool investigating a mechanism of toxic effect caused by xylene.
Abstract:
The present invention relates to microRNAs for identifying exposure to lower aliphatic saturated aldehydes and an identification method using the same. More specifically, the present invention selects one kind of microRNA which is overexpressed until expression level becomes 1.5 times or more due to exposure to the lower aliphatic saturated aldehydes and one kind of microRNA which is lessexpressed until expression level becomes 0.66 times or less and uses two kinds of the microRNAs as biomarkers in order to monitor and judge risk of the lower aliphatic saturated aldehydes and as a tool for investigating mechanism of toxic activities caused by the lower aliphatic saturated aldehydes.

Abstract:
The present invention relates to a biomarker for identifying specific exposure to lower aliphatic saturated aldehydes, one of volatile organic compounds exposed in the environment, and a method for identification using the same and, more specifically, a biomarker of which the gene expression is up- or down-regulated specifically by lower aliphatic saturated aldehydes and a method for identifying specific exposure to lower aliphatic saturated aldehydes using the biomarker. The biomarker in the present invention can be useful for monitoring or evaluating lower aliphatic saturated aldehyde contamination in the environmental samples using genes selected by DNA microarray chip as the biomarkers and be used as a tool for investigating the toxic mechanism specifically induced by the lower aliphatic saturated aldehydes.
