Gene expression analysis. The results are expressed as—fold difference over carrier control. Eukaryotic 18S rRNA was used as the endogenous control. Fold difference inferior to 0 were expressed as negative numbers (e.g., a—fold difference of 0.50 is expressed as −2.00). Results presented as mean ± standard deviation. Variation between +1 and −1, corresponds to no change, are represented by the dotted lines. Statistical significance was calculated based on the mean ΔCT values by Student’s-t test; **denotes P < 0.01 and *** denotes P < 0.001 versus carrier control
