However, colorectal neoplasia is characterised by dysregulated transporter biology, and Lee et al. reported markedly increased expression of organic anion transporting polypeptide 1B3 (OATP1B3) in colon tumours relative to normal tissue, with immunohistochemical detection in the majority of colon adenocarcinomas [59]. Here, SLCO1B3 is linked to colon adenocarcinoma.
