Effect of Primary Smoking on eNOS and Its Regulatory Proteins

Nonsmokers Primary smokers
N 84 5
eNOS protein, pg/μg protein 14.0 ± 1.8 6.9 ± 2.4a
eNOS activity, cpm/mg/min 3350 ± 422 2294 ± 1761
eNOS mRNA, relative unit 0.18 ± 0.04 0.31 ± 0.31
NOx, μM/μg protein 0.311 ± 0.01 0.26 ± 0.05
Hsp90, relative intensity 0.95 ± 0.15 0.53 ± 0.34
Caveolin-1, relative intensity 0.95 ± 0.08 0.63 ± 0.15

Using analyses of variance, we tested the homogeneity in variance of the measured variables between smokers and nonsmokers. They were not significantly different for levels of eNOS protein and mRNA, NOx, Hsp90 and Caveolin-1.
