Perfluoroalkyl substances (PFASs) like PFOS promote lung cancer cell growth by inhibiting apoptosis and enhancing migration. This study reveals PFOS activates the PI3K/AKT/NF-κB pathway, contributing to lung adenocarcinoma development.
Area of Science:
- Environmental Health
- Toxicology
- Oncology
Background:
- Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are widespread synthetic chemicals.
- Perfluorooctanesulfonic acid (PFOS) exposure is linked to health issues, but its role in lung cancer is unclear.
Purpose of the Study:
- Investigate PFOS effects on lung adenocarcinoma (LUAD) cell lines.
- Elucidate the carcinogenic mechanisms of PFOS in LUAD.
Main Methods:
- Evaluated PFOS-induced proliferation, anti-apoptotic properties, and epithelial-mesenchymal transition (EMT) in H1299 and A549 LUAD cells.
- Examined PI3K/AKT/NF-κB pathway activation and its role in apoptosis inhibition.
Main Results:
- PFOS significantly promoted LUAD cell growth by suppressing apoptosis.
- PFOS accelerated EMT, enhancing cell migration.
- PFOS activated the PI3K/AKT/NF-κB pathway, facilitating proliferation and migration.
Conclusions:
- PFOS exposure may exacerbate lung conditions or induce carcinogenesis.
- PFOS suppresses apoptosis and activates PI3K/AKT/NF-κB signaling in LUAD.
- Findings provide evidence for PFOS's carcinogenic potential in lung adenocarcinoma.
