A Large-Scale Human Toxicogenomics Resource for Drug-Induced Liver Injury Prediction

ABSTRACT: Drug-Induced Liver Injury (DILI) remains one of the most critical challenges in drug development, causing patient safety concerns, clinical trial failures and drug withdrawals. We introduce ToxPredictor, a toxicogenomics framework combining RNA-seq data from primary human hepatocytes with pharmacokinetic data to predict dose-resolved DILI risks and safety margins. At its core is DILImap, an RNA-seq library tailored for DILI research, comprising 300 compounds at multiple concentrations. ToxPredictor achieves 88% sensitivity at 100% specificity in blind validation, outperforming state-of-the-art methods. It flagged recent phase III clinical failures, including Evobrutinib, TAK-875, and BMS-986142, overlooked by animal studies. Beyond prediction, ToxPredictor provides mechanistic insights into hepatotoxic pathways, enabling early de-risking and actionable safety decisions. Unlike single-endpoint readouts—even from 3D models—transcriptomics offers a multi-dimensional system-level view of hepatocyte responses, capable of detecting diverse DILI mechanisms not captured by conventional assays. Scalable, actionable, and integrated into a broader AI/ML drug discovery platform, this work establishes toxicogenomics as a transformative tool for developing safer therapeutics and addressing one of the most pressing challenges in toxicology.

Comparative hepatic transcriptome analyses revealed possible pathogenic mechanisms of fasiglifam (TAK-875)-induced acute liver injury in mice

Project description:Fasiglifam (TAK-875), a G protein-coupled receptor 40 (GPR40) agonist, was a drug candidate for type 2 diabetes. However, its development was terminated in phase 3 trials due to liver safety concerns. Although TAK-875 was reported to inhibit hepatobiliary transporters and disturb bile acid disposition, pathogenic mechanisms of TAK-875-induced liver injury are not fully understood. In this study, we sought to identify the mechanisms with a hepatic genome-wide transcriptomic analysis in a murine model. We demonstrated that, among the three GPR40 agonists, TAK-875, AMG-837 and TUG-770, only TAK-875 induced acute liver injury in mice. Transcriptome profiles of TAK-875-exposed liver was compared with those of non-hepatotoxic analogues AMG-837 and TUG-770 as negative controls and those of classical hepatotoxicants concanavalin A and carbon tetrachloride as positive controls. The comparative hepatic transcriptome analyses revealed the enrichment of genes involved in inflammation, endoplasmic reticulum (ER) stress, apoptosis, and hepatic lipid accumulation, suggesting that these events play pathophysiologic roles in the development of TAK-875-induced liver injury. These results were validated by quantitative PCR with significant changes in chemokines, danger signals, ER stress mediators, proapoptotic factors, and hepatic steatosis markers only in TAK-875-exposed liver. Pretreatment of TAK-875-administered mice with an ER stress inhibitor 4-phenylbutyric acid (4-PBA) alleviated the liver injury. Consistent with the in vivo study, pretreatment of HepG2 cells with 4-PBA significantly improved the decrease of cell viability induced by TAK-875. In conclusion, by a comprehensive transcriptomic analysis of GPR40 agonists, we found multiple possible processes that contribute to TAK-875-induced acute liver injury in mice.

Toxicogenomic module associations with pathogenesis: A network based approach to understanding drug toxicity (ChIP-Seq)

Project description:Despite investment in toxicogenomics, nonclinical safety studies are still used to predict clinical liabilities for new drug candidates. Network-based approaches for genomic analysis help overcome challenges with whole-genome transcriptional profiling using limited numbers of treatments for phenotypes of interest. Herein, we apply co-expression network analysis to safety assessment using rat liver gene expression data to define 415 modules, exhibiting unique transcriptional control, organized in a visual representation of the transcriptome (the ‘TXG-MAP’). Accounting for the overall transcriptional activity resulting from treatment, we explain mechanisms of toxicity and predict distinct toxicity phenotypes using module associations. We demonstrate that early network responses compliment traditional histology-based assessment in predicting outcomes for longer studies and identify a novel mechanism of hepatotoxicity involving endoplasmic reticulum stress and Nrf2 activation. Module-based molecular subtypes of cholestatic injury derived using rat translate to human. Moreover, compared to gene-level analysis alone, combining module and gene-level analysis performed in sequence identifies significantly more phenotype-gene associations, including established and novel biomarkers of liver injury.

PHH Chlorpromazine

Project description:Drug induced liver injury (DILI) is still a major reason for drug attrition during clinical trials and market-withdrawal of already approved drugs. DILI is difficult to predict in animal models, hence more suitable screening methods are needed to predict adverse effects in human. Here, transcriptomic data from short- and long-term cultured primary human hepatocytes exposed to the human hepatotoxin Chlorpromazine was analysed.

Polygenic architecture informs potential vulnerability to drug-induced liver injury

Project description:Drug-Induced-Liver-Injury (DILI) is a leading cause of termination in drug development programs and removal of drugs from the market because of inability to identify potential patients prior to clinical testing. Here, we approached a polygenic risk score (PRS) based strategy by aggregating effects of numerous genome-wide loci identified from previous large-scale genome-wide association studies (GWAS). The PRS predicted the susceptibility to DILI in patients in a clinical trial, and in multi-donor derived primary hepatocytes and stem cell-derived organoids. Pathway analysis highlighted processes previously implicated in DILI, including unfolded protein responses and oxidative stress alleviated by a potent antioxidant. Furthermore, hepatocytic transcriptomic signatures related to polygenic score identified potential drugs with clinical DILI evidence through in silico 941 compound screening. This genetic-, cellular-, organoid- and human-scale evidence underscored the polygenic architectures underlying DILI vulnerability at the level of hepatocytes, thus facilitating future mechanistic studies. Moreover, the proposed “polygenicity-in-a-dish” strategy potentially will contribute to prospective designs of safer, more efficient, and robust clinical trials.

Direct detection of circulating microRNA-122 using dynamic chemical labelling with single molecule detection overcomes stability and isomiR challenges for biomarker qualification

Project description:Circulating microRNAs are biomarkers reported to be stable and translational acrossspecies. miR-122 (miR-122-5p) is a hepatocyte-specific microRNA biomarker for drug-induced liver injury (DILI). Our objective was to develop an extraction-free andamplification-free detection method for measuring miR-122 that has translationalutility in context of DILI. We developed a single molecule dynamic chemical labelling(DCL) assay based on miR-122 hybridization to an abasic peptide nucleic acid probethat contained a reactive amine instead of a nucleotide at a specific position in thesequence. The single molecule DCL assay specifically measured miR-122 directly from10 μL of serum or plasma without any extraction steps, with a fit-for-purpose limit ofdetection of 1.32 pM. In 192 human serum samples, DCL accurately identified patientsat risk of DILI (area under ROC curve 0.98 (95%CI 0.96-1), P<0.0001). The miR-122assay also quantified liver injury in rats and dogs. When DCL beads were added toserum, the miR-122 signal was stabilised (no loss of signal after 14 days at roomtemperature). By contrast, there was substantial degradation of miR-122 in the absenceof beads (≈60% lost in 1 day). RNA sequencing demonstrated the presence of multiplemiR-122 isomiRs with DILI that were at low concentration or not present in healthypatient serum. Sample degradation over time produced more isomiRs, particularlyrapidly with DILI. PCR was inaccurate when analysing miR-122 isomiRs, whereas theDCL assay demonstrated accurate quantification. In summary, the DCL assay canaccurately measure miR-122 directly from serum and plasma to diagnose liver injury inhumans and other species, and can overcome important microRNA biomarker analyticaland biological challenges.

RNA-sequencing with human liver organoids derived from human induced pluripotent stem cells

Project description:We established a human liver organoid (HLO) based screening model for analyzing DILI pathology at organoid resolution. HLO contains polarized immature hepatocytes with bile canaliculi-like architecture, establishing the unidirectional bile acid transport pathway. Single cell RNAseq profiling identified diverse and zonal hepatocytic populations that in part emulate primary adult hepatocytes. By developing a 384 well based high-speed live imaging platform, we successfully developed a Liver organoid-based Toxicity screen (LoT) with multiplexed readouts measuring viability, cholestatic and/or mitochondrial toxicity. We functionally validated LoT with 238 marketed drugs at 4 different concentrations. LoT positively predicts genomic predisposition (CYP2C9*2) for Bosentan-induced cholestasis. Thus, LoT is a high-fidelity model for drug safety with a cost-effective platform, facilitating compound optimization, mechanistic study, and precision medicine as well as drug screening applications.

An in vitro coculture system of human peripheral blood mononuclear cells with hepatocellular carcinoma-derived cells for predicting drug-induced liver injury

Project description:Preventing clinical drug-induced liver injury (DILI) remains a major challenge because DILI develops via multifactorial mechanisms. Immune and inflammatory reactions are considered important mechanisms of DILI; however, biomarkers from in vitro systems using immune cells have not been comprehensively studied. The aims of this study were 1) to identify promising biomarker genes for predicting DILI in an in vitro coculture model of peripheral blood mononuclear cells (PBMCs) with a human liver cell line, and 2) to evaluate these genes as predictors of DILI using a panel of drugs with different clinical DILI risk. Transcriptome-wide analysis of PBMCs cocultured with HepG2 or differentiated HepaRG cells that were treated with several drugs revealed an appropriate separation of DILI-positive and DILI-negative drugs, from which 12 putative biomarker genes were selected. To evaluate the predictive performance of these genes, PBMCs cocultured with HepG2 cells were exposed to 77 different drugs, and gene expression levels in PBMCs were determined. The MET proto-oncogene receptor tyrosine kinase (MET) showed the highest area under the receiver operating characteristic curve (AUC) value of 0.81 among the 12 genes with a high sensitivity/specificity (85/66%). However, a stepwise logistic regression model using the 12 identified genes showed the highest AUC value of 0.94 with a high sensitivity/specificity (93/86%). Taken together, we established a coculture system using PBMCs and HepG2 cells and selected biomarkers that can predict DILI risk. The established model would be useful in detecting the DILI potential of compounds, in particular those that involve an immune mechanism.

Identification of Specific MicroRNA Biomarkers in Early Stage of Hepatocellular injury, Cholestasis, and Steatosis in Rat

Project description:Recently, study on circulating microRNAs (miRNAs) as potential biomarkers of drug-induced liver injury (DILI), has received increasing attention. It has been demonstrated that miR-122 and miR-192, which are liver enriched, could be potential biomarkers of DILI, however, these miRNAs cannot discern types of injuries. In the present study, we comprehensively analyzed time-dependent plasma miRNA profiles in rats with drug- or chemical-induced hepatocellular injury, cholestasis, and steatosis with high-throughput miRNA sequencing. To enable comparison of miRNA expression levels between DILI models with different severity and peaks of injuries, stages of injury were defined as early, middle and late, according to cluster patterns of miRNA expression profiles. Through differential analysis, we characterized miRNAs that were specifically up- or down-regulated in each DILI model. Interestingly, several miRNAs were dramatically changed earlier than traditional biomarkers such as ALT and AST. For example, in APAP-induced hepatocellular injury model, let-7b-5p was up-regulated as early as 3 h after dosing, while significant change in ALT level was observed at 24 h. Thereafter, we focused on the DILI type-specific miRNAs which were up-regulated at early stage of injury. RT-qPCR study validated that let-7b-5p and miR-1-3p for hepatocellular injury, miR-143-3p and miR-218a-5p for cholestasis, and miR-320-3p for steatosis models have shown significant increase in the early stage of the injuries. The present study suggests the utility of miRNAs as specific biomarkers for early detection of DILI.
