Abstract
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are synthetic chemicals widely used in consumer and industrial sectors, with PFOS being particularly notable for its extensive applications. However, PFOS exposure has been associated with health issues, and while its biotoxicity—especially carcinogenic effects—has been documented, the specific risks and mechanisms in lung cancer remain unclear. This study investigates the effects of PFOS on lung adenocarcinoma (LUAD) cell lines and elucidates its carcinogenic mechanisms. We evaluated PFOS-induced proliferation in H1299 and A549 LUAD cells, focusing on its anti-apoptotic properties and impact on epithelial-mesenchymal transition (EMT), while also examining activation of the PI3K/AKT/NF-κB pathway and its role in apoptosis inhibition. Results show PFOS significantly promotes H1299 and A549 cell growth via anti-apoptotic effects, accelerates EMT in LUAD cells to enhance migration, and activates the PI3K/AKT/NF-κB pathway to facilitate proliferation and migration. These findings suggest PFOS exposure may exacerbate pre-existing lung conditions or induce carcinogenesis by suppressing apoptosis and activating PI3K/AKT/NF-κB signaling, providing evidence for PFOS-related carcinogenic potential in LUAD.
期刊介绍:
Food and Chemical Toxicology (FCT), an internationally renowned journal, that publishes original research articles and reviews on toxic effects, in animals and humans, of natural or synthetic chemicals occurring in the human environment with particular emphasis on food, drugs, and chemicals, including agricultural and industrial safety, and consumer product safety. Areas such as safety evaluation of novel foods and ingredients, biotechnologically-derived products, and nanomaterials are included in the scope of the journal. FCT also encourages submission of papers on inter-relationships between nutrition and toxicology and on in vitro techniques, particularly those fostering the 3 Rs.
The principal aim of the journal is to publish high impact, scholarly work and to serve as a multidisciplinary forum for research in toxicology. Papers submitted will be judged on the basis of scientific originality and contribution to the field, quality and subject matter. Studies should address at least one of the following:
-Adverse physiological/biochemical, or pathological changes induced by specific defined substances
-New techniques for assessing potential toxicity, including molecular biology
-Mechanisms underlying toxic phenomena
-Toxicological examinations of specific chemicals or consumer products, both those showing adverse effects and those demonstrating safety, that meet current standards of scientific acceptability.
Authors must clearly and briefly identify what novel toxic effect (s) or toxic mechanism (s) of the chemical are being reported and what their significance is in the abstract. Furthermore, sufficient doses should be included in order to provide information on NOAEL/LOAEL values.
