COPD is characterised by poorly reversible airflow obstruction usually due to
cigarette smoking. The transcription factor clusters of ?-catenin/Snail1/Twist
has been implicated in the process of epithelial mesenchymal transition (EMT), an
intermediate between smoking and airway fibrosis, and indeed lung cancer. We have
investigated expression of these transcription factors and their "cellular
localization" in bronchoscopic airway biopsies from patients with COPD, and in
smoking and non-smoking controls. An immune-histochemical study compared cellular
protein expression of ?-catenin, Snail1 and Twist, in these subject groups in 3
large airways compartment: epithelium (basal region), reticular basement membrane
(Rbm) and underlying lamina propria (LP). ?-catenin and Snail1 expression was
generally high in all subjects throughout the airway wall with marked cytoplasmic
to nuclear shift in COPD (P?0.01). Twist expression was generalised in the
epithelium in normal but become more basal and nuclear with smoking (P?0.05).
In addition, ?-catenin and Snail1 expression, and to lesser extent of Twist, was
related to airflow obstruction and to expression of a canonical EMT biomarker
(S100A4). The ?-catenin-Snail1-Twist transcription factor cluster is up-regulated
and nuclear translocated in smokers and COPD, and their expression is closely
related to both EMT activity and airway obstruction.
