(A) Immunoblots of total protein tyrosine nitration in the lung tumor (T) and nontumor (NT) of LC and LC-COPD patients. (B) Mean values and standard deviation (optical densities (OD) expressed in arbitrary units (a.u.)) of total protein tyrosine nitration levels were significantly increased in the tumor (T) lesions compared with nontumor (NT) lungs in LC patients. Total protein tyrosine nitration was also significantly higher in nontumor (NT) lung specimens of LC-COPD as a group compared with nontumor (NT) parenchyma of LC patients. The absence of any statistical sign means that no significant differences were found between groups for the different study comparisons. MW, molecular weights; KDa, kilodaltons.
