SLCO1B3 and hepatocellular carcinoma: To explore whether SLC transports participated in the uptake of MHI-148 into HCC cells, the fluorescence intensity of MHI-148 was assessed in SNU-739 after transfection of specific siRNAs against six kinds of SLC transporters which are mainly localized in hepatocytes (including OATP1B3, NTCP, OATP1B1, OAT2, OATP2B1 and OCT1).
