Project description:Sorafenib is the only approved targeted drug for hepatocellular carcinoma (HCC), but its effect on patients’ survival gain is limited and varies over a wide range depending on patho-genetic conditions. Thus, enhancing the efficacy of sorafenib and finding a reliable predictive biomarker are crucuial to achieve efficient control of HCCs. In this study, we employed a systems approach by combining transcriptome analysis of the mRNA changes in HCC cell lines in response to sorafenib with network analysis to investigate the action and resistance mechanism of sorafenib. Gene ontology and gene set analysis revealed that proteotoxic stress and apoptosis modules are activated in the presence of sorafenib. Further analysis of the endoplasmic reticulum (ER) stress network model combined with in vitro experiments showed that introducing an additional stress by treating the orally active protein disulfide isomerase (PDI) inhibitor (PACMA 31) can synergistically increase the efficacy of sorafenib in vitro and in vivo, which was confirmed using a mouse xenograft model. We also found that HCC patients with high PDI expression show resistance to sorafenib and poor clinical outcomes, compared to the low PDI expression group. These results suggest that PDI is a promising therapeutic target for enhancing the efficacy of sorafenib and can also be a biomarker for predicting sorafenib responsiveness.

Project description:Sorafenib resistance up-regulated circRNA_104797 could be transmitted by exosomes and responsible for the spread of Sorafenib resistance among HCC cells. CircRNA_104797 was critical for Sorafenib resistance maintenance and silencing circRNA_104797 could substantially increase the efficacy of Sorafenib by inducing apoptosis. Mechanism dissection unveiled that circRNA_104797 could specifically sponge miR-103a-2-5p and miR-660-3p and act as a competing endogenous RNA (ceRNA), thus competitively activated wnt/β-catenin pathway and induced Sorafenib resistance. Meanwhile, LC-MS/MS also revealed that circRNA_104797 could specifically bind to translation related proteins, which might regulate downstream glycan biosynthesis and lipid metabolism, and finally induce Sorafenib resistance. In vivo experiments portrayed a promising clinical application by locally injection of in vivo-grade siRNA for circRNA_104797 by TACE or other manners, which could intensively enhance Sorafenib efficacy in HCC patients. The clinical application of in vivo-grade siRNA for circRNA_104797 in Sorafenib treated HCC patients might shed bright future for the management of advanced HCC.

Project description:Sorafenib is associated with cardiac adverse effects, including left ventricular dysfunction. However, the precise mechanism remains unclear. Here, we aimed to establish the genes responsible for this cardiotoxicity using zebrafish. A pigmentless zebrafish line expressing green fluorescent protein in the heart were treated with or without sorafenib. In vivo fluorescent cardiac imaging revealed that the ventricular dimension of the longitudinal axis in zebrafish treated with sorafenib was significantly lower than in those without sorafenib. Transcriptome analysis of zebrafish hearts revealed that expression of stanniocalcin1 (stc1) in zebrafish treated with sorafenib was significantly lower than that without sorafenib treatment. We were able to demonstrate that the ventricular dimension of the longitudinal axis in stc1 morphant was significantly smaller than that of control zebrafish and that forced expression of stc1 normalized the decrease in ventricular diameter in stc1 morphant and zebrafish treated with sorafenib. These data suggest that stc1 is the gene responsible for sorafenib-induced cardiotoxicity. Gene expression regulated by sorafenib in zebrafish at 4 dpf was measured. Four independent experiments were performed for each group.

Project description:Three HL cell lines (HD-MyZ, L-540 and HDLM-2) were used to investigate the effects of perifosine and sorafenib using in vitro assays analyzing cell growth, cell cycle distribution, gene expression profiling (GEP), and apoptosis. Western blotting (WB) experiments were performed to determine whether the two-drug combination affected MAPK and PI3K/AKT pathways as well as apoptosis. Additionally, the antitumor efficacy and mechanism of action of perifosine/sorafenib combination were investigated in vivo in nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice using tumor growth rates and survival as endpoints. RESULTS: While perifosine and sorafenib as single agents exerted a limited activity against HL cells, exposure of HD-MyZ and L-540 cell lines, but not HDLM-2 cells, to perifosine/sorafenib combination resulted in synergistic cell growth inhibition (40% to 80%) and cell cycle arrest. Upon perifosine/sorafenib exposure, L-540 cell line showed significant levels of apoptosis (up to 70%, P ?.0001) associated with severe mitochondrial dysfunction (cytochrome c, apoptosis-inducing factor release and marked conformational change of Bax accompanied by membrane translocation). Apoptosis induced by perifosine/sorafenib combination did not result in processing of caspase-8, -9, -3, or cleavage of PARP, and was not reversed by the pan-caspase inhibitor Z-VADfmk, supporting a caspase-independent mechanism of cell death. In responsive cell lines, WB analysis showed that antiproliferative and pro-apototic events were associated with dephosphorylation of MAPK and PI3K/Akt pathways. GEP analysis of HD-MyZ and L-540 cell lines, but not HDLM-2 cells indicated that perifosine/sorafenib treatment induced upregulation of genes involved in amino acid metabolism and downregulation of genes regulating cell cycle, DNA replication and cell death. In addition, in responsive cell lines, perifosine/sorafenib combination strikingly induced the expression of tribbles homologues 3 (TRIB3) both in vitro and in vivo. Silencing of TRIB3 prevented cell growth reduction induced by perifosine/sorafenib treatment. In vivo, the combined perifosine/sorafenib treatment significantly increased the median survival of NOD/SCID mice xenografted with HD-MyZ cell line as compared to controls (81 vs 45 days, P ?.0001) as well as mice receiving perifosine alone (49 days, P ?.03) or sorafenib alone (54 days, P ?.007). In mice bearing subcutaneous nodules generated by HD-MyZ and L-540 cell lines but not HDLM-2 cell line, perifosine/sorafenib treatment induced significantly increased levels of apoptosis (2- to 2.5-fold, P ?.0001) and necrosis (2- to 8-fold, P ?.0001), as compared to controls or treatment with single agents. In addition, perifosine/sorafenib treatment had no effect on HDLM-2 nodules, but significantly reduced L-540 nodules with 50% tumor growth inhibition, compared to controls. CONCLUSIONS: Perifosine/sorafenib combination resulted in strong anti-HL activity both in vitro and in vivo. These results warrant clinical evaluation of perifosine/sorafenib combined-treatment in HL patients. The Hodgkin lymphoma cell line L-540 was obtained from the DSMZ (Braunschweig, Germany, EU). Cells were routinely maintained in RPMI medium 1640 (Lonza, Basel, Switzerland) supplemented with 20% FBS (Lonza) and 2 mM glutamine (Lonza). Cells were maintained at 37°C in a water-saturated atmosphere of 5% CO2 in air. 10x10^6 L-540 cells were seeded in 75 cm2 flask and, after 24 hrs, cells were treated with 10 µM perifosine (Aeterna Zentaris, Frankfurt, Germany, EU) and/or 5 µM sorafenib (Bayer, Berlin,?Germany, EU) in culture medium for 24 hours. At the end of treatment, cells were collected and RNA extracted.

Project description:Hepatocellular carcinoma (HCC) is the second prominent cause of cancer-associated death worldwide. Usually, HCC is diagnosed in advanced stages, where sorafenib, a multiple target ty-rosine kinase inhibitor, is used as the first line of treatment. Unfortunately, resistance to sorafenib is usually encountered within six months of the treatment. Therefore, there is a critical need to identify the underlying reasons for drug resistance. In the present study, we investigated the proteomic and metabolomics alterations accompanying to sorafenib resistance in hepatocellular carcinoma Hep3B cells by employing ultra-high-performance liquid chromatography quadrupole time of flight mass spectrometry (UHPLC-QTOF-MS). The Bruker Human Metabolome Database (HMDB) library was used to identify the differentially abundant metabolites through MetaboScape 4.0 software (Bruker). For protein annotation and identification, the Uniprot proteome for Homo sapiens (Human) da-tabase was utilised through MaxQuant. The results revealed that 27 metabolites and 18 proteins were significantly dysregulated due to sorafenib resistance in Hep3B cells compared to the parental phenotype. D-alanine, L-proline, o-tyrosine, succinic acid and phosphatidylcholine (PC, 16:0/16:0) were among the significantly altered metabolites. Ubiquitin carboxyl-terminal hydrolase isozyme L1, mitochondrial superoxide dismutase, UDP-glucose-6-dehydrogenase, sorbitol dehydrogenase and calpain small subunit 1 were among the significantly altered proteins. The findings revealed that resistant Hep3B cells demonstrated significant alterations in amino acid and nucleotide met-abolic pathways, energy production pathways and other pathways related to cancer aggressive-ness, migration, proliferation, and drug-resistance. Joint pathway enrichment analysis unveiled unique pathways, including the antifolate resistance pathway and other important pathways that maintain cancer cells' survival, growth, and proliferation. Collectively, the results identified po-tential biomarkers for sorafenib-resistant HCC and gave insights into their role in chemotherapeutic drug resistance, cancer initiation, progression, and aggressiveness, which may contribute to better prognosis and chemotherapeutic outcomes.
