Hsp60 and Hsp10 down-regulation predicts bronchial epithelial carcinogenesis in smokers with chronic obstructive pulmonary disease.

2006

BACKGROUND. The relation between smoking, chronic obstructive pulmonary disease (COPD), and lung cancer (LC) is an open field of investigation. A higher frequency of adenocarcinoma has been reported in patients with COPD. Heat shock proteins (Hsps) are implicated in tumoral cell growth and differentiation. The aim of the present study was to investigate the expression of Hsp60 and Hsp10 in bronchial biopsies from smokers with COPD and in 10 lung cancer patients and to evaluate the association between Hsps expression and carcinogenetic steps of LC. METHODS. An immunohistochemical study was performed for Hsp60 and Hsp10 in bronchial biopsies from 35 COPD (postbronchodilator forced expiratory …
