Objective:
To observe the differentially expressed genes of the human normal liver cell (L-02) induced by low concentration of trichloroethylene (TCE).
Methods:
The dose-effect relation of TCE toxicity was analyzed by means of MTT. 5 micromol/L was chosen as low concentration while 40 micromol/L as high concentration. Then L-02 were treated with low concentration, high concentration, pretreated with low concentration then attacked with high concentration of TCE respectively. Fluorescence differential display polymerase chain reaction (Fluoro DD-PCR) was used to search differentially expressed genes of the different treatment groups of TCE. Results 51 differential expressed strap were found, 11 differential straps have been cloned and sequenced. 9 of them were known gene, while 2 of them were new genes.
Conclusion:
The differential straps would be identified to provide scientific base for research deeply the mechanism of low concentration TCE inducing adaptive response of L-02.
