Abstract:
Introduction:Air pollution has become one of the major problems in socio-economic and health
issues in Mongolia. Among the various hazards of particulate matter (PM) pollutants, microorganisms
in PM2.5 and PM10 are thought to be responsible for various allergies and for the spread of respiratory
diseases. Recent studies have shown that PM2.5 particles can cause chronic heart failure, heart
arrhythmias, and strokes, as well as lung damage, cirrhosis, inflammation, cancer, cardiovascular
disease, and metabolic disorders. Furthermore, some studies have concluded that PM2.5 particles
in the environment are a risk factor for gastrointestinal, liver, colon, and lung cancer as well as it
affects the growth and metastasis of various cancer cells caused by other factors. In our country, the
health effects of air pollution and the relationship between the pathogenesis of cancer research are
scarce. Therefore, the study of the effects of PM2.5 particles on cancer cell proliferation, migration
(metastasis) can provide a significant role for cancer treatment, diagnosis, and prevention.
Purpose:Determining the effects of PM2.5 particles on cancer cell proliferation, migration (metastasis)
in in-vitro
Material and Methods:A human liver cancer cell line (HepG2), human gastric cancer cell line (AGS)
were obtained from the central scientific research laboratory in the Institute of medical sciences.
HepG2, AGS cells were seeded at a concentration of 1*105 cells/mL in a culture flask and cultured
in RPMI-1640 medium supplemented with 10% FBS, 1% antibiotic mix (penicillin, streptomycin) in a
humidified atmosphere of 5% CO2 at 37 °C. The cytotoxic effect of PM 2.5 in AGS, HepG2 cells were
evaluated by MTT, CCK8 assays. AGS, HepG2 cells were incubated in 96 well plates for 24h then
treated with different concentrations (0, 5, 10, 25, 50 and 100 μg ) of Bayankhoshuu, Buhiin urguu,
and Zaisan samples for 24h, respectively.
Results:Concentrations of 10, 25, and 50 μg/ml of samples collected from the Bukhiin urguu and
Zaisan in March increased HepG2 cell growth, while doses of 25, 50 μg/ml of samples collected from
Bayankhoshuu in March and December increased HepG2 cell growth. Therefore, concentrations of
25 and 50 μg/ml of samples collected from Bayankhoshuu in March increased AGS cell growth, while concentrations of 25, 100 and μg/ml of samples collected in December increased AGS cell growth.
However, no cytotoxic effect was observed in the sample collected from Zaisan in March, whereas
the PM2.5 sample enhanced AGS cell growth in dose dependent manner in December.(p <0.05)
Conclusion:High levels of heavy metals were detected in samples collected in December from
Bayankhoshuu, Bukhiin urguu and Zaisan of Ulaanbaatar. Concentration of 25 μg/ml of samples
collected from the Bukhiin urguu and Zaisan in March increased HepG2 cell growth. Concentrations
of 25 μg/ml of PM2.5 collected from three regions around Ulaanbaatar increased HepG2 and AGS
cell migration.
