The human bronchial epithelial cells (HBE) and K-ras-silenced HBE cells were treated with fine particulate matter (PM2.5) samples from Taiyuan for 24 h. To screen the proteomic characteristics of PM2.5-induced differentially expressed proteins (DEPs), the Q Exactive mass spectrometer was used. Gene ontology (GO) analysis, Kyoto encyclopedia of genes and genomes (KEGG) analysis, functional prediction, protein–protein interaction (PPI) network analysis, and visualization of differential protein interactions were performed. 251 DEPs in K-ras sile...
