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.

Project description:TAK-243 is a first-in-class inhibitor of ubiquitin-like modifier activating enzyme 1 (UBA1) that catalyzes ubiquitin activation, the first step in the ubiquitylation cascade. Based on its preclinical efficacy and tolerability, TAK-243 has been advanced to phase 1 clinical trials in advanced malignancies. Nonetheless, the determinants of TAK-243 sensitivity remain largely unknown. Here, we conducted a genome-wide CRISPR/Cas9 knockout screen in acute myeloid leukemia (AML) cells in the presence of TAK-243 to identify genes essential for TAK-243 action. We identified BEN domain-containing protein 3 (BEND3), a transcriptional repressor and a regulator of chromatin organization, as the top gene whose knockout confers resistance to TAK-243

Project description:SUMOylation, a post-translational modification of the ubiquitin family plays a critical role in the regulation of proteins function and fate. TAK-981 (Subasumstat) is a first-in-class inhibitor of the SUMO-activating enzyme used in various phase I/II clinical trials for solid tumors and lymphomas. In addition to its direct cytotoxic effect on cancer cells, TAK-981 activates anti-tumor immune response. We show here that TAK-981 activates human natural killer cells. TAK-981 mostly regulates genes involved in inflammation and immune response, in particular those related to the type-I and type-II interferon pathway.

Project description:We performed scRNA-seq analyses to determine the transcriptional landscape of the TAK-931-induced aneuploid cells at the single-cell levels. HeLa cells were treated with DMSO or TAK-931 (300 nM) for 72 h. In the t-SNE plots, the DMSO- and TAK-931-treated cells were classified in two distinct clusters. Indicating that the major population of the TAK-931-treated aneuploid HeLa cells was transformed to a cell contexture that was transcriptionally distinct from that of DMSO-treated control cells. The hallmark of an inflammatory response was remarkably enriched in the TAK-931 treatment cluster. In addition, the positive cells of inflammatory cytokine/chemokine-related genes, such as CXCL8, IL1B, TNHSF14 and TNFRSF1B, were significantly accumulated in the TAK-931-treatment cluster.

Project description:Acute Myeloid Leukemias (AML) are severe hematomalignancies with dismal prognosis. The post-translational modification SUMOylation plays key roles in leukemogenesis and AML response to therapies. Here, we show that TAK-981 (subasumstat), a first-in-class SUMOylation inhibitor, is endowed with potent anti-leukemic activity in various preclinical models of AML. TAK-981 targets AML cell lines and patient blast cells in vitro and in vivo in xenografted mice with minimal toxicity on normal hematopoietic cells. Moreover, it synergizes with 5-azacitidine (AZA), a DNA-hypomethylating agent now used in combination with the BCL-2 inhibitor venetoclax to treat AML patients unfit for standard chemotherapies. Interestingly, TAK-981+AZA combination shows higher anti-leukemic activity than AZA+venetoclax combination both in vitro and in vivo, at least in the models tested. Mechanistically, TAK-981 potentiates the transcriptional reprogramming induced by AZA, promoting apoptosis, alteration of the cell cycle and differentiation of the leukemic cells. In addition, TAK-981+AZA treatment induces many genes linked to inflammation and immune response pathways. In particular, this leads to the secretion of type I interferon (IFN-I) by AML cells. Finally, TAK-981+AZA induces the expression of Natural Killer (NK)-activating ligands (MICA/B) and adhesion proteins (ICAM-1) at the surface of AML cells. Consistently, TAK-981+AZA-treated AML cells activate NKs and increase their cytotoxic activity. Targeting SUMOylation with TAK-981 may thus be a promising strategy to both sensitize AML cells to AZA and reduce their immune-escape capacities.

Project description:Eight (8) male mice (4 matched pairs) from each of 45 Collaborative Cross lines were treated with a single oral (gavage) dose of either vehicle (methylcellulose) or TAK-875 (600 mg/kg) to facilitate the evaluation of very early liver events in the pathogenesis of IDILI and the identification of genetic risk factors that influence toxicity susceptibility at the hepatocyte level Microarray profiling in the liver identified treatment-induced changes differing by strain and correlating with serum liver chemistries that were enriched in mitochondrial dysfunction, oxidative stress, bile acid homeostasis and immune response pathways suggesting multiple mechanisms contribute to TAK-875 toxicity. Candidate risk factor genes were then identified using individual-transcript and pathway-based mapping of the expression data and further support the contribution of these mechanisms to TAK-875 toxicity.

Project description:SUMOylation is a reversible post-translational modification that has been implicated in the regulation of various cellular processes including inflammatory responses and expression of Type I interferons (IFN1). In this report, we have explored the activity of the selective small molecule SUMOylation inhibitor TAK-981 in promoting antitumor innate immune responses. We demonstrate that treatment with TAK-981 results in IFN1-dependent macrophage and NK cell activation, promoting macrophage phagocytosis and NK cell cytotoxicity in ex vivo assays. Furthermore, pre-treatment with TAK-981 enhanced macrophage phagocytosis or NK cell cytotoxicity against CD20-positive target cells in combination with the anti-CD20 antibody rituximab. In vivo studies demonstrated synergistic antitumor activity of TAK-981 and rituximab in CD20-positive lymphoma xenograft models. TAK-981 is currently being studied in phase 1 clinical trials (NCT03648372, NCT04074330, NCT04776018, and NCT04381650) for the treatment of patients with lymphomas and solid tumors.
