Abstract:
Objective To investigate the pathogen-related genes of atmospheric polluting disease so as to clarify the biology mechanism and provide the scientific basis.Methods By using the technique of dot blot hybridization,we analyzed genes’differential expression with cloning by exposure to ≥75 μg/m3 PM2.5 in heating season and < 75 μg/m3 PM2.5 in un-heating season in WI-38 human embryo lung cells.The levels of cytokines TNF-α,IL-2, IL-6 and IL-8 were determined by radio immunity assay. Results After 24h of treatment, compared with control group,more than 100μg/mL PM2.5 significantly increased TNF-α,IL-6 and IL-8 levels,and decreased IL-2 in WI-38 human embryo lung cells (P < 0.05 ).The clear stripe was found in 350 bp in 48 gene samples with segment with differential expression of genes exposed to different concentrations of PM2.5 in WI-38 human embryo lung cells.Through the dot blot hybridization,black brown spots were found in 41 samples in Tester cDNA hybridization,and no similar spots were found in all of the same samples in Driver cDNA hybridization. Conclusion PM2.5 exposure may induce the inflammatory damage of WI-38 human embryo lung cells.Obvious genetic damage was observed in those cells exposed to ≥75 μg/m3 PM2.5 in heating season.
