Increased perfluorooctanoic acid accumulation facilitates the migration and invasion of lung cancer cells via remodeling cell mechanics.

ABSTRACT: Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are widely used in industrial and household products, raising serious concerns due to their environmental persistence and mobility. Epidemiological studies have reported potential carcinogenic risks of PFAS based on their widespread occurrence and population exposure. In this study, we observed that perfluorooctanoic acid (PFOA), a common PFAS, functions as a mechanical regulator in lung cancer cells. PFOA exposure reduces cell stiffness, thereby decreasing cell adhesion and enhancing immune evasion, ultimately exacerbating tumor metastasis. In various lung cancer models, more aggressive tumor metastases have been observed in the PFOA exposure group. Additionally, serum PFOA levels in patients with advanced lung adenocarcinoma were signi
