We further analyzed a number of human gastric cancer data sets deposited at the Oncomine website, a cancer microarray database and data-mining platform [22], and identified significantly higher expression of select OATPs, including OATP1B3, OATP2B1, OATP3A1, OATP4A1 and OATP5A1, in gastric cancer patient samples compared to normal tissue samples (Figure 4D). The gene discussed is SLCO5A1; the disease is cancer.
