[0059]In the present study, Applicant tested bile transport activity using Fluorescein Diacetate, which was excreted by MRP2 across the canalicular membrane into the bile canalicular networks (Tian et al., 2004). It has previously been reported that Troglitazone and Cyclosporin inhibit the MRP2 (Chang et al., 2013; Lechner et al., 2010). In addition, the efflux transporter MRP2 mediates export of Bosentan (Fahrmayr et al., 2013). Although the inhibition of MRP2 by Nefazodone was not reported, mitochondria stress by Nefazodone may be related to a decrease of the bile transport activity, efflux of Fluorescein Diacetate, because MRP2 is an ATP-dependent bile salt transporter for canalicular excretion of bile acids in hepatocytes.
[0060]Preclinical detection of risk compounds for drug induced liver injury (DILI) remains a significant challenge in drug development, highlighting a need for a predictive human system. Here, Applicant developed a human liver organoid (HLO) model for analyzing...
