Effects of e-cigarette liquids on metabolic cooperation and Cx43 protein expression. A Metabolic cooperation: number of 6-TG-R V79 surviving colonies in mixed co-cultures of 100 6-TG-R and 0.75 × 106 WT cells normalised to seeding controls (100 6-TG-R cells treated the same way as co-cultures). B Densitometric quantification of Cx43 protein expression normalised to tubulin. Data are presented as mean ± SEM from three separate experiments of independent cell preparations. * p < 0.05; **p < 0.01 versus negative control. C Western blot of Cx43 and tubulin as endogenous control in V79 cells after 72 h treatments, blot is representative of three separate experiments and cropped from original image (Additional file 7: Fig. S7)
