We present an in vitro study of lung epithelial and fibroblastic cell lines exposed to growing concentrations (5%, 10%) of cigarette smoke extract (CSE), and to N-acetylcysteine. The heme oxygenase 1 (HO-1) gene expression was stimulated by CSE in a dose-dependent manner in both immortalized bronchial epithelium (BEAS 2B) and foetal pulmonary fibroblasts (HFL1), whereas no effect was seen in lung adenocarcinoma cells (A549). HO-1 gene expression, differently regulated in the three cell lines, seems to be provoked by CSE induced oxidative stress.

Abstract
We present an in vitro study of lung epithelial and fibroblastic cell lines exposed to growing concentrations (5%, 10%) of cigarette smoke extract (CSE), and to N-acetylcysteine. The heme oxygenase 1 (HO-1) gene expression was stimulated by CSE in a dose-dependent manner in both immortalized bronchial epithelium (BEAS 2B) and foetal pulmonary fibroblasts (HFL1), whereas no effect was seen in lung adenocarcinoma cells (A549). HO-1 gene expression, differently regulated in the three cell lines, seems to be provoked by CSE induced oxidative stress.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
