Homo sapiens whole genome expression microarray of peripheral blood monocytes obtained from Control Smokers, Control Never Smokers, COPD Smokers and COPD ExSmokers.

Differential profiles from whole genome human expression arrays on monocytes obtained from peripheral blood in COPD was studied and compared with controls. Monocytes were isolated from Controls (Group 1) which included Control Smokers (Group 1A) and Control Never Smokers (Group 1B) and COPD (Group 2) which included COPD Smokers (Group 2A) and COPD ExSmokers (Group 2B). Differential transcriptomic expression associated with (i) Smoking, (ii) COPD, and (iii) cessation of smoking were identified. Whole genome expression arrays of peripheral blood monocytes using total RNA obtained from Control Smokers, Control Never Smokers, COPD Smokers and COPD ExSmokers.
