Abstract

<p>The numbers of signals in case of which 10 μM O-methyl-l-tyrosinyl-γ-l-glutamyl-l-cysteinylglycine (UPF1)/2 mM N-acetylcysteine (NAC) significantly reduced the effect of the respective stimuli are shown in parentheses.</p><p>The numbers of mass spectrometry signals (mass-to-charge ratios) from the lysate of primary normal human bronchial epithelial cells cultured in air-liquid interface significantly (p<i><</i>0.05) altered by e-cigarette liquid (ECL) (100 μM by nicotine) or 10 μg/mL cigarette smoke condensate (CSC) at the respective time points.</p
