<i>In vitro</i>, TGF-β1-stimulated BEAS-2B cells were treated with 1,8-cineol to analyze EMT markers (α-SMA, E-cadherin, N-cadherin), migration capacity, and NF-κB/COX-2 signaling using RT-qPCR, Western blotting, and transwell assays.<h4>Results</h4>1,8-cineol significantly attenuated airway hyperresponsiveness and reduced EMT markers (α-SMA, N-cadherin) in OVA-sensitized mice, while improving lung compliance. Here, ACTA1 is linked to airway hyperresponsiveness.
