- Abstract: Fine particulate matter (PM2.5) has attracted more and more attention in the field of environmental pollution and public health. Previous studies have found that PM2.5 can be inhaled and deposit in the airway and alveoli, and even spread to the whole-body tissues and organs through blood, resulting in various toxic effects. The malignant transformation of lung epithelial cells associated with long-term exposure to PM2.5 may play an important role in the occurrence and development of lung cancer. This paper reviewed recent studies on the mechanisms of malignant transformation of lung epithelial cells associated with PM2.5 exposure, and discussed the main biological mechanisms, including epigenetics, tumor microenvironment, and other biological pathways. Besides, the potential research directions of malignant transformation of lung epithelial cells associated with PM2.5 exposure were proposed. This work aims to provide a scientific basis and reference for public health management and air quality assessment.
