Project description:Rates of hepatocellular carcinoma (HCC) are increasing rapidly due to the epidemic of metabolic dysfunction-associated steatohepatitis (MASH). In addition to increased incidence, emerging evidence suggests that MASH driven HCC is associated with poor survival outcomes potentially due to the complex liver microenvironment which is characterized by hypoxia, steatosis, and fibrosis. Lenvatinib, is a multi-tyrosine kinase inhibitor, that is a standard of care therapy for unresected HCC, but 5-year survival rates are less than 20%. Therefore, developing treatments that inhibit cancer growth kinetics and target the tumor microenvironment to improve the therapeutic response in MASH-HCC are needed. Salsalate is a rheumatoid arthritis therapy that stimulates the AMP-activated protein kinase (AMPK) increasing fatty acid oxidation while reducing de-novo lipogenesis, fibrosis and cell proliferation pathways. Thus, we hypothesized that Salsalate could improve the therapeutic efficacy of Lenvatinib in MASH-HCC. In the current study, we show that treatment of human HCC cells with clinically relevant concentrations of Lenvatinib and Salsalate synergistically suppress proliferation and clonogenic survival, activate AMPK and inhibit the mTOR-HIF1a and Erk1/2 signaling pathways. In orthotopic xenograft and MASH-HCC mouse models Lenvatinib and Salsalate combination therapy suppressed angiogenesis and steatosis and fibrosis. RNA-sequencing revealed combination therapy enhanced mitochondria fatty acid oxidation and suppressed glycolysis, angiogenesis, fibrosis and cell cycle progression with regulatory network analysis suggesting a potential role for Activating transcription factor 3 (ATF3) and ETS-proto-oncogene-1 (ETS1). These data suggest that Lenvatinib and Salsalate combination therapy may have therapeutic potential for MASH-HCC due to effective metabolic rewiring and growth inhibition, leading to improvements in the liver microenvironment and inhibition of HCC proliferation.

Project description:Metabolic dysfunction-associated steatohepatitis is a form of chronic liver inflammation associated with metabolic syndrome, such as obesity and a major cause of hepatocellular carcinoma. Multi-biotics, a soymilk fermented with lactic acid bacteria, are known to alleviate obesity by lowering lipid profile. In this study, we investigated efficacy of multi-biotics in MASH-related HCC using mouse model fed choline-deficient L-amino acid-defined high-fat diet, and determined that tumor regression was not affected by multi-biotics. We established mouse MASH-related HCC organoids, and performed RNA-sequencing to identify transcriptomic features in MASH-HCC treated multi-biotics. We also examined response of MASH-related HCC to four HCC treatment drugs, and MASH-related HCC treated multi-biotics was good response to Lenvatinib. We established Lenvatinib-resistant MASH-related HCC organoids by administrating repeatedly Lenvatinib, and identified enriched pathways in Lenvatinib-resistant models. This study provides a tool for studying MASH-related HCC treatment and Lenvatinib resistance by establishing the MASH-related HCC and Lenvatinib resistance organoid model.

Project description:Lenvatinib is the FDA-approved targeted drug for advanced hepatocellular carcinoma (HCC), but the efficacy is modest due to drug resistance. Tumor kinome re-wiring governs drug resistance in resistant cancer cells, which is an obstacle for efficient cancer therapy. Therefore, identification the kinases critical for this rewiring process in HCC is crucial.This study reveals the new role of CDK6 and its mechanistic insight in regulation of cancer stemness and drug resistance. These results support the combination treatment of lenvatinib with palbociclib for advanced HCC patients. Further studies will optimize patient target selection and identify the best treatment combinations.

Project description:Lenvatinib is a multiple receptor tyrosine kinases inhibitor (TKI) authorized for first-line treatment of hepatocellular carcinoma (HCC). However, Lenvatinib resistance is common in HCC clinical treatment, highlighting the urgent need to understand mechanisms of resistance. Here, we identified Golgi membrane protein 1 (GOLM1), a type II transmembrane protein originally located in the Golgi apparatus, as a novel regulator of Lenvatinib resistance. We established Lenvatinib resistance in human HCC cell lines PLC/PRF/5. Through RNA-seq, we found that GOLM1 was significantly upregulated, which was further validated in patients derived tumor tissue and peripheral blood. GOLM1 overexpression contributes to Lenvatinib resistance and HCC progression in vitro and in vivo. Mechanistically, GOLM1 upregulates CSN5 expression through EGFR-STAT3 pathway. Reversely, CSN5 deubiquitinates and stabilizes GOLM1 protein by inhibiting ubiquitin-proteasome pathway of GOLM1. Collectively, our data demonstrate that GOLM1 is one of the key driver of Lenvatinib resistance in HCC and depicts a molecular network in Lenvatininb resistant HCC cells.

Project description:Lenvatinib targets multiple oncogenic kinases including vascular endothelial growth factor receptors (VEGFRs) and showed longer median progression-free survival than sorafenib, the only approved treatment for >10 years. With the successful combination therapy of anti-PD-L1 pembrolizumab and anti-VEGF bevacizumab for advanced HCC as well as encouraging experimental findings, lenvatinib was also expected to enhance anti-tumor effects by combining anti-PD-1 pembrolizumab compared to lenvatinib alone; however, the phase III clinical trial failed to show their synergetic survival benefits, highlighting the need for elucidating its mode of action in human HCC specimens after lenvatinib treatment. We performed multi-layer transcriptome analyses of surgically resected human HCC samples after lenvatinib treatment as a neo-adjuvant therapy using RNA-sequencing. Molecular pathway analyses and immunohistochemistry revealed that VEGF-mediated aberrant vascularity and cytotoxic GZMK+CD8 T cells infiltration were significantly improved in lenvatinib-treated HCC; however, the majority of these cytotoxic T cells were trapped in the intratumor fibrotic stroma, suggesting that lenvatinib-treated HCC is in the so-called excluded condition. Excluded tumors are generally believed to be less responsive to immune checkpoint inhibitors, which might be the reason the combination therapy failed to show the additive benefits.

Project description:Abstract: Cancer-associated fibroblasts (CAFs) play an important role in the induction of chemo-resistance. The objectives of this study were to clarify the mechanism underlying CAF-mediated sorafenib/lenvatinib resistance and identify a novel therapeutic target to overcome resistance to sorafenib/lenvatinib in hepatocellular carcinoma (HCC). Methods: Whole transcriptome sequencing (WTS) data of nine pairs of CAFs and para-cancer-associated fibroblasts (PAFs) were analyzed to identify key molecules that induce resistance to tyrosine kinase inhibitors (TKIs). In vitro and in vivo experiments were performed to validate selected targets and related mechanisms. Plasma secreted phosphoprotein 1 (SPP1) expression levels prior to sorafenib/lenvatinib treatment as well as progression-free survival (PFS) and overall survival (OS) of an advanced HCC cohort (n=42) were evaluated using Kaplan–Meier analysis. Results: Co-culturing CAFs and HCC cells significantly reduced the responsiveness of HCC cells to sorafenib/lenvatinib, in vitro and in vivo. Systematic integrative analysis of the WTS data of CAFs/PAFs and publicly available gene expression data indicated that CAF-derived SPP1 (CAF-SPP1) was suitable for use as a candidate molecule to induce sorafenib/lenvatinib resistance. An evaluation of the mechanisms involved indicated that CAF-SPP1 increased phosphorylation of PKCɑ, which then activated rapidly accelerated fibrosarcoma (RAF)-extracellular signal-related kinase 1/2-signal transducer and activator of transcription 3 (STAT3) and phosophoinositide 3-kinase (PI3K)-AKT-mechanistic target of rapamycin kinase (mTOR) in HCC cells. SPP1 inhibitors reversed CAF-induced sorafenib/lenvatinib resistance in vitro and in vivo. Patients showing high plasma SPP1 prior to sorafenib/lenvatinib treatment exhibited significantly poor PFS (P=0.005) and OS (P=0.041). Conclusions: CAF-SPP1 enhances sorafenib/lenvatinib resistance in HCC by alternatively activating oncogenic pathways via PKCɑ phosphorylation. Inhibition of CAF-SPP1 may be utilized as a therapeutic strategy against TKI resistance in HCC. Plasma SPP1 level prior to TKI treatment shows potential as a promising biomarker for predicting sorafenib/lenvatinib response in advanced HCC patients.

Project description:Modulation of metabolic, inflammatory, and fibrotic pathways by semaglutide in metabolic dysfunction-associated steatohepatitis Metabolic dysfunction-associated steatohepatitis (MASH) is a chronic liver disease strongly associated with cardiometabolic risk factors. Semaglutide, a glucagon-like peptide-1 receptor agonist, improves liver histology in MASH, but the underlying signals and pathways driving semaglutide-induced MASH resolution are not well understood. We show that, in two preclinical MASH models, semaglutide improved histological markers of fibrosis and inflammation, and reduced hepatic expression of fibrosis- and inflammation-related gene pathways.
