Abstract

Chronic obstructive pulmonary disease (COPD) is associated with chronic severe airway inflammation and causes increasing global health problems. New biological markers for COPD prediction and prognosis are urgently necessary. Previous studies indicate that histone deacetylases (HDACs) play essential roles in COPD. This study is to investigate if HDAC2 levels can be used as a promising, easily detected biomarker of COPD. In this paper, 49 COPD patients were enrolled and 42 healthy individuals (smokers or non-smokers) were used as healthy controls. Human bronchial epithelial cells derived from non-smokers, smokers, or COPD patients were grown in primary cultures. Total proteins were harvested from lung tissues or bronchial epithelial cells and then subjected to immunoblot analyses of HDAC2, HDAC3, and HDAC5. Quantitative RT-PCR analysis of HDAC2, HDAC3, and HDAC5 mRNA levels in tissues or cells were also preformed. We found that among the three HDAC proteins, the mRNA and protein levels of HDAC2, but not HDAC3 and HDAC5, in the tissues or cultured cells from patients have a significant correlation with development and prognosis of COPD. These results suggested that HDAC2 levels may serve as a promising, easily detected biomarker of COPD.
