Patent ID: 8716192

Claim:
A method for the identification of exposure to a lower aliphatic saturated aldehyde selected from the group consisting of butyraldehyde, heptanal, octanal, propionaldehyde, valeraldehyde and nonanal, comprising the following steps: 1) measuring an expression level of a micro RNA (ribonucleic acid) hsa-miR-590-5p with a nucleotide sequence of SEQ. ID. NO: 1, and a micro RNA hsa-miR-28-5p with a nucleotide sequence of SEQ. ID. NO: 2 in somatic cells isolated from an experimental group and a normal control group, respectively; and 2) determining the experimental group to be exposed to: a) butyraldehyde, heptanal or octanal when the expression level of micro RNA accession number hsa-miR-590-5p is down-regulated in the somatic cells isolated from the experimental group in comparison with the somatic cells from the normal control group; and b) propionaldehyde, valeraldehyde or nonanal when the expression level of micro RNA accession number hsa-miR-28-5p is up-regulated in the somatic cells isolated from experimental group comparison with the somatic cells isolated from the normal control group.
