NTPDase1/CD39 Gene Expression in Human Lung Tissue Samples. Relative mRNA levels of CD39 analyzed in the COPD (n = 15), NOS (n = 13) and NS (n = 11) groups, normalized to 18 S mRNA levels and expressed as fold changes. Data are expressed as median ± rank. *Significantly different from NS and NOS (P < 0.05). Abbreviations: NTPDase1, nucleoside triphosphate diphosphohydrolase-1; COPD, Chronic obstructive pulmonary disease; NOS, Non-obstructed smokers; NS, Never smoker
