F-β(E) for 48 h. B: Increased expression of Tn was detected by Western blot analysis in cell lysates after stimulation with TGF-β(B) for 48 h. The data were quantified by densitometry and are expressed as fold increases above non-stimulated cells (mean ± SEM) (n = 12). D: Augmented expression of Tn protein was detected by flow cytometry in response to LTDcombined with TGF-β, compared with the effect of LTDalone. Difference from isotype control mean fluorescence intensity (MFI) is presented (mean ± SEM). Presence of 5 mM L-cysteine in the culture media did not affect the expression levels of Tn (D, E). *p < 0.05, **p < 0.01, and ***p < 0.001 vs. non-stimulated cells.

not with LTE(B) for 48 h. RT-PCR analysis detected increased expression of Ln β2 chain mRNA in response to 100 nM LTD(D), but no effect with either LTE(D) or TGF-β(E). The increase in response to LTDwas concentration-dependent. The data were quantified by densitometry and are expressed as fold increases above non-stimulated cells (mean ± SEM) (n = 12). *p < 0.05 and ***p < 0.001 vs. non-stimulated cells. C: Immunoperoxidase immunocytochemistry for Ln β2 chain showing no definite expression of Ln β2 chain by non-stimulated control cells with a slight increase after treatment with both LTDand LTE.

Synthesis of tenascin and laminin beta2 chain in human bronchial epithelial cells is enhanced by cysteinyl leukotrienes via CysLTreceptor-4
Xpression to the levels not differing from that in non-stimulated cells. Difference from isotype control mean fluorescence intensity (MFI) is presented. B: RT-PCR analysis of Tn mRNA showing inhibition of the cysteinyl leukotriene-induced up-regulation by both MLK and BAY u9773. Partial inhibition of Tn expression induced by combined LTDand TGF-βdown to the level not differing from that what was seen after stimulation with TGF-βalone was shown at both protein (A) and mRNA (B) level. There was no statistical difference between the inhibitory effects of MLK and BAY u9773 in any setting. Data are expressed as mean ± SEM (n = 12) *p < 0.05, **p < 0.01, and ***p < 0.001.

Principal component analysis of the metabolic state of primary normal human bronchial epithelial cells cultivated in air-liquid interface after exposure to (A) e-cigarette liquid (ECL) (100 μM by nicotine) and (B) 10 μg/mL cigarette smoke condensate (CSC) (black solid lines).
<p>The time points at the arrow turns are 1, 2, 5, 7, and 13 h. Long dashes: Addition of 10 μM O-methyl-l-tyrosinyl-γ-l-glutamyl-l-cysteinylglycine to the cells having been exposed to ECL for 1 h (the arrow starts at 2 h time point), short dashes: Addition of 2 mM N-acetylcysteine to the cells having been exposed to ECL for 1 h (the arrow starts at 2 h time point). For each treatment and for any time point, n = 3 (gray circles). Error bars indicate standard errors of means. PComp1 and PComp2 are the two principal components describing the highest fraction of the effect of cells’ metabolome.</p
