- Abstract: As a mineral material widely used in life, chrysotile is a public health concern for its fibrogenicity and carcinogenicity. Currently, more than 50 countries have completely banned the import and use of chrysotile, but China is still the world's largest consumer and second largest producer of chrysotile, with a large occupationally exposed population. Investigations have shown that chrysotile miners are significantly more likely to develop pulmonary fibrosis, lung cancer, and mesothelioma than workers in other occupations. Chrysotile-induced cancers generally have a decades-long latency period and are difficult to diagnose and treat in a timely manner. Therefore, the cancer fatality due to chrysotile exposure is significant and is a leading contributor to occupational cancer death. Epithelial mesenchymal transition is a key step in the biological processes of chronic inflammation, fibrosis, carcinogenesis, and cancer metastasis in tissues and organs, also plays an important role in pulmonary fibrosis, lung cancer, and other diseases due to chrysotile exposure. This paper summarized the mechanisms of chrysotile inducing epithelial interstitial transition from dynamics of inflammatory factors, mitogen-activated protein kinase pathways, oxidative stress, and other biological pathways, and proposed possible research directions for further study on chrysotile-induced epithelial mesenchymal transition, aiming to provide a reliable basis and reference for in-depth research on pulmonary fibrosis, lung cancer, and other diseases due to chrysotile exposure.
