Recently, we have made our first report on the identification of the cancer-type organic anion transporting polypeptide 1B3 (Ct-OATP1B3, [GenBank: NM_019844 (for SLCO1B3, gene symbol) and GenBank: AB669023 (for the alternative region)] in human colon and lung cancers [5], and other research groups have subsequently confirmed its existence in colon and pancreas cancers [6],[7]. This evidence concerns the gene SLCO1B3 and lung cancer.
