Environmental chemical carcinogens are major factors in the induction of lung cancer, with benzo[a]pyrene (B[a]P) being one most widespread and highly carcinogenic among them. Although studies have reported that B[a]P exerts its effects by causing mutations, inducing cytotoxicity, inhibiting DNA synthesis, early molecular regulatory events mechanisms involved B[a]P-induced tumor initiation remain unclear. This study found MGAT3 gene was significantly downregulated mouse tumorigenesis, suggesting important tumor-suppressive function. Further investigation revealed suppression expression promoted invasion migration abilities cancer cells, while overexpression these cells inhibited effects. Western blot analysis also showed regulated epithelial-mesenchymal transition markers, thereby affecting motility cells. Xenograft assay confirmed inhibitory effect on proliferation. Analysis tissue further validated is tissues, this decrease associated a poor prognosis patients. Our research indicates downstream molecules plays crucial role development induced environmental carcinogens.
