mRNA expression of breast cancer-resistance protein (BCRP), occludin and claudin-5 in P.1 PBEC. (A) Normalised mRNA expression levels of BCRP, occludin and claudin-5 for P.1 PBEC cultures. P.1 PBEC mRNA data for each gene were normalised against GAPDH (mean±SEM, n=12; independent-sample t-test; ***p<0.0001). Statistical significance between the three genes was determined by one-way ANOVA, followed by Dunnet's test for equal variances (***p<0.0001). (B) Absolute mRNA expression levels of GAPDH and BCRP. mRNA transcripts are from 12 samples (mean±SEM; independent-sample t-test; **p<0.01).
