Objective:To screen the differential methylation sites, genes and pathways of air pollution fine particles (PM
2.5) on human bronchial epithelial (HBE) cells by methylation chip and bioinformation technology, so as to provide scientific basis for further study of the toxicological mechanism of PM
2.5 on HBE cells.
Methods:In August 2020, HBE cells were infected with 10 μg/ml and 50 μg/ml PM
2.5 aqueous solution for 24 h, namely PM
2.5 10 μg/ml exposure group (low dose group) and PM
2.5 50 μg/ml exposure group (high dose group) ; uni...
