Researchers to use novel metabolomics technology for COPD
Date:7/16/2012

NEW YORK (July 12, 2012) -- at Weill Cornell Medical College were awarded a $6.5 million grant from the National Heart, Lung, and Blood Institute for a five-year investigation into metabolic changes occurring within airway epithelial cells in the lungs of chronic obstructive pulmonary disease (COPD) patients caused by cigarette smoking. In addition, researchers aim to identify which cigarette smokers are at highest risk of developing COPD as well as novel biomarkers to assist in the development of new therapeutic treatments for the disease.

One-fifth of the adult population in the United States smokes cigarettes, and each puff can burden the human lungs with a hundred trillion oxidants and more than 4000 chemical compounds. Cigarette smoking is a major cause of disease, including COPD, the fourth leading cause of death of Americans. There is currently no cure, no effective treatments beyond oxygen therapy and no biomarkers to diagnose the disease early.

"Twenty percent of smokers get COPD, so it is vital that we identify who is at the highest risk and why," says Dr. Ronald G. Crystal, co-principal investigator for the study and chairman of genetic medicine at Weill Cornell Medical College. "Gaining a better understanding of COPD's underlying biology and the metabolic changes forced by cigarette smoke to airway epithelial cells will help us effectively deal with this major health problem. We can use this information to develop new ways to protect the lungs."

Smoking-induced COPD patients can experience shortness of breath and loss of lung function due to the severe narrowing of their lung airways. COPD is associated with the progression of "ciliopathy," the cellular dysfunction within the airway epithelial cells that leads to the shortening of cilia cells, mucus accumulation and the impairment of infection defenses. The majority of epithelial cells are made up of cilia, important cells in lung health that play the crucial role of movi
