Among normal tissues, OATP1A2 (SLCO1A2) is expressed in the intestinal epithelium[111], the renal epithelium, and highly in brain capillary endothelial cells.[112] Altered OATP1A2 expression has been detected in glioma, colon polyps and cancers, and breast cancers as compared to normal tissues. Here, SLCO1A2 is linked to glioma.
