Fig 1 Sevoflurane inhibited cell viability of A549 cells. (A) Alamar Blue reduction of naïve, control and sevoflurane-treated A549 cells at 24 h post gas exposure (n=3). (B) Alamar Blue absorbance after inhibition of TGF-βRI/II with LY (LY21) at 24h post gas exposure (n=3). (C) Wound healing at 24 h post sevoflurane exposure in cultures with and without 24 h of 40 μM DDP treatment. Images are X4 magnification. Dashed-line indicates initial wound at t = 0h. (D) Wound/gap closure expressed as percentage remaining wound area at 24h post gas exposure. 24h data naive (n=4), control (n=4), sevo (n=4), naive + DDP (n=3), control + DDP (n=3), sevo + DDP (n=3). N=number of independent experiments. (E) Wound healing after siRNA knockdown of TGF-β1 and OPN at 24h post gas exposure (n=6). SSi=scramble RNA negative control, TSi=TGF-β1 SiRNA-treated, OSi=OPN SiRNA-treated. Data are expressed as mean (SEM) and analysed using one-way ANOVA with Tukey's post hoc test. *P<0.05, **P<0.01, ***P<0.001.

Fig 2 Effect of sevoflurane on TGF-β1 expression in A549 cells. TGF-β1 expression in A549 cells detected by immunofluorescence staining. Mean fluorescent intensity is displayed as a box and whisker plot with mean plus or minus upper and lower limits (n=6). Data are expressed as mean (SEM) and analysed using Kruskal-Wallis with Dunn's post hoc test. British Journal of Anaesthesia , DOI: ( /j.bja ) Copyright © Terms and Conditions

(A) Nuclear Smad3 expression in DDP-treated A549 cells as detected by immunofluorescence staining at 24 h post sevoflurane exposure. Fluorescent intensity of Smad3 displayed as a box-and-whisker plot with mean upper and lower limits. Naive + DDP (n=3), Control + DDP (n=3) Sevo + DDP (n=4). Data were analysed with Kruskal-Wallis with Dunn's post hoc test. ***P<0.001. British Journal of Anaesthesia , DOI: ( /j.bja ) Copyright © Terms and Conditions

(A) TGF-βRII expression in DPP-treated RCC4 cells was detected by immunofluorescence staining at 24 h post sevoflurane exposure. Fluorescent intensity of TGF-βRII displayed as box-and-whisker plot with mean plus or minus upper and lower limits. Naive + DDP (n=3), Control + DDP (n=4), Sevo + DDP (n=4). (B) Nuclear Smad3 expression in DDP-treated RCC4 cells was detected by immunofluorescence staining at 24 h post sevoflurane exposure. Fluorescent intensity of Smad3 displayed as a box-and-whisker plot with mean plus or minus upper and lower limits. Naive + DDP (n=4), Control + DDP (n=4), Sevo + DDP (n=3). Data were analysed using Kruskal-Wallis with post hoc Dunn's test. **P<0.01, ***P<0.001. British Journal of Anaesthesia , DOI: ( /j.bja ) Copyright © Terms and Conditions
