About the cover: Expression of OCT3 protein in hepatocellular carcinoma and corresponding liver tissue. Immunohistochemical staining of drug uptake transporter OCT3 was performed on formalin-fixed and paraffin-embedded tissue samples from nontumor tissue (F) and HCC tissue of trabecular (G) or pseudoglandular (H) growth pattern. The median staining scores (blue horizontal lines) for OCT3 were significantly lower in HCC tissue than in nontumor tissue (E, P < 0.001). Scale bars, 20 μm. See the article by Namisaki et al. (dx.doi.org/10.1124/dmd.114.059832).
