Synergistic anti-tumor efficacy of sorafenib and fluvastatin in hepatocellular carcinoma.

ABSTRACT: Drug resistance to sorafenib is common in patients with hepatocellular carcinoma(HCC). We examined the effects of a combination of sorafenib and fluvastatin on HCC using in vitro and in vivo models. The dual treatment induced apoptosis and reduced cellular viability in HCC more effectively than either drug alone. The combination treatment also inhibited activation of hepatic stellate cells, whereas single drug treatments did not. On a molecular level, combined treatment inhibited activation of the MAPK and NF-?B pathways via Toll-like receptor 4 in HCC cells. Combined treatment also inhibited expression of stromal cell-derived factor 1? in HCC cells, which further inhibited the MAPK pathway in hepatic stellate cells. These results suggest that a combination of sorafenib and fluvastatin may be a promising therapeutic strategy for patients with advanced HCC.

Apigenin enhances sorafenib anti-tumour efficacy in hepatocellular carcinoma.

Project description:BackgroundThe "one drug-one target" paradigm has various limitations affecting drug efficacy, such as resistance profiles and adverse effects. Combinational therapies help reduce unexpected off-target effects and accelerate therapeutic efficacy. Sorafenib- an FDA-approved drug for liver cancer, has multiple limitations. Therefore, it is recommended to identify an agent that increases its effectiveness and reduces toxicity. In this regard, Apigenin, a plant flavone, would be an excellent option to explore.MethodsWe used in silico, in vitro, and animal models to explore our hypothesis. For the in vitro study, HepG2 and Huh7 cells were exposed to Apigenin (12-96 μM) and Sorafenib (1-10 μM). For the in vivo study, Diethylnitrosamine (DEN) (25 mg/kg) induced tumor-bearing animals were given Apigenin (50 mg/kg) or Sorafenib (10 mg/kg) alone and combined. Apigenin's bioavailability was checked by UPLC. Tumor nodules were studied macroscopically and by Scanning Electron Microscopy (SEM). Biochemical analysis, histopathology, immunohistochemistry, and qRT-PCR were done.ResultsThe results revealed Apigenin's good bioavailability. In silico study showed binding affinity of both chemicals with p53, NANOG, ß-Catenin, c-MYC, and TLR4. We consistently observed a better therapeutic efficacy in combination than alone treatment. Combination treatment showed i) better cytotoxicity, apoptosis induction, and cell cycle arrest of tumor cells, ii) tumor growth reduction, iii) increased expression of p53 and decreased Cd10, Nanog, ß-Catenin, c-Myc, Afp, and Tlr4.ConclusionsIn conclusion, Apigenin could enhance the therapeutic efficacy of Sorafenib against liver cancer and may be a promising therapeutic approach for treating HCC. However, further research is imperative to gain more in-depth mechanistic insights.

Hexokinase-II Inhibition Synergistically Augments the Anti-tumor Efficacy of Sorafenib in Hepatocellular Carcinoma.

Project description:This study aimed to examine whether inhibition of hexokinase (HK)-II activity enhances the efficacy of sorafenib in in-vivo models of hepatocellular carcinoma (HCC), and to evaluate the prognostic implication of HK-II expression in patients with HCC. We used 3-bromopyruvate (3-BP), a HK-II inhibitor to target HK-II. The human HCC cell line was tested as both subcutaneous and orthotopic tumor xenograft models in BALB/c nu/nu mice. The prognostic role of HK-II was evaluated in data from HCC patients in The Cancer Genome Atlas (TCGA) database and validated in patients treated with sorafenib. Quantitative real-time PCR, western blot analysis, and immunohistochemical staining revealed that HK-II expression is upregulated in the presence of sorafenib. Further analysis of the endoplasmic reticulum-stress network model in two different murine HCC models showed that the introduction of additional stress by 3-BP treatment synergistically increased the in vivo/vitro efficacy of sorafenib. We found that HCC patients with increased HK-II expression in the TCGA database showed poor overall survival, and also confirmed similar results for TCGA database HCC patients who had undergone sorafenib treatment. These results suggest that HK-II is a promising therapeutic target to enhance the efficacy of sorafenib and that HK-II expression might be a prognostic factor in HCC.

EZH1/2 inhibition augments the anti-tumor effects of sorafenib in hepatocellular carcinoma.

Project description:Both EZH2 and its homolog EZH1 function as histone H3 Lysine 27 (H3K27) methyltransferases and repress the transcription of target genes. Dysregulation of H3K27 trimethylation (H3K27me3) plays an important role in the development and progression of cancers such as hepatocellular carcinoma (HCC). This study investigated the relationship between the expression of EZH1/2 and the level of H3K27me3 in HCC. Additionally, the role of EZH1/2 in cell growth, tumorigenicity, and resistance to sorafenib were also analyzed. Both the lentiviral knockdown and the pharmacological inhibition of EZH1/2 (UNC1999) diminished the level of H3K27me3 and suppressed cell growth in liver cancer cells, compared with EZH1 or EZH2 single knockdown. Although a significant association was observed between EZH2 expression and H3K27me3 levels in HCC samples, overexpression of EZH1 appeared to contribute to enhanced H3K27me3 levels in some EZH2lowH3K27me3high cases. Akt suppression following sorafenib treatment resulted in an increase of the H3K27me3 levels through a decrease in EZH2 phosphorylation at serine 21. The combined use of sorafenib and UNC1999 exhibited synergistic antitumor effects in vitro and in vivo. Combination treatment canceled the sorafenib-induced enhancement in H3K27me3 levels, indicating that activation of EZH2 function is one of the mechanisms of sorafenib-resistance in HCC. In conclusion, sorafenib plus EZH1/2 inhibitors may comprise a novel therapeutic approach in HCC.

Synergistic antitumor activity of sorafenib and MG149 in hepatocellular carcinoma cells.

Project description:Advanced hepatocellular carcinoma (HCC) is among the most challenging cancers to overcome, and there is a need for better therapeutic strategies. Among the different cancer drugs that have been used in clinics, sorafenib is considered the standard first-line drug for advanced HCC. Here, to identify a chemical compound displaying a synergistic effect with sorafenib in HCC, we screened a focused chemical library and found that MG149, a histone acetyltransferase inhibitor targeting the MYST family, exhibited the most synergistic anticancer effect with sorafenib on HCC cells. The combination of sorafenib and MG149 exerted a synergistic anti-proliferation effect on HCC cells by inducing apoptotic cell death. We revealed that cotreatment with sorafenib and MG149 aggravated endoplasmic reticulum (ER) stress to promote the death of HCC cells rather than adaptive cell survival. In addition, combined treatment with sorafenib and MG149 significantly increased the intracellular levels of unfolded proteins and reactive oxygen species, which upregulated ER stress. Collectively, these results suggest that MG149 has the potential to improve the efficacy of sorafenib in advanced HCC via the upregulation of cytotoxic ER stress.

Nano lipidic carriers for codelivery of sorafenib and ganoderic acid for enhanced synergistic antitumor efficacy against hepatocellular carcinoma.

Project description:The current study focuses on the development and evaluation of nano lipidic carriers (NLCs) for codelivery of sorafenib (SRF) and ganoderic acid (GA) therapy in order to treat hepatocellular carcinoma (HCC). The dual drug-loaded NLCs were prepared by hot microemulsion technique, where SRF and GA as the drugs, Precirol ATO5, Capmul PG8 as the lipids, while Solutol HS15 and ethanol was used as surfactant and cosolvents. The optimized drug-loaded NLCs were extensively characterized through in vitro and in vivo studies. The optimized formulation had particle size 29.28 nm, entrapment efficiency 93.1%, and loading capacity 14.21%. In vitro drug release studies revealed>64% of the drug was released in the first 6 h. The enzymatic stability analysis revealed stable nature of NLCs in various gastric pH, while accelerated stability analysis at 25◦C/60% RH indicated the insignificant effect of studied condition on particle size, entrapment efficiency, and loading capacity of NLCs. The cytotoxicity performed on HepG2 cells indicated higher cytotoxicity of SRF and GA-loaded NLCs as compared to the free drugs (p < 0.05). Furthermore, the optimized formulation suppressed the development of hepatic nodules in the Wistar rats and significantly reduced the levels of hepatic enzymes and nonhepatic elements against DEN intoxication. The SRF and GA-loaded NLCs also showed a significant effect in suppressing the tumor growth and inflammatory cytokines in the experimental study. Further, histopathology study of rats treated SRF and GA-loaded NLCs and DEN showed absence of necrosis, apoptosis, and disorganized hepatic parenchyma, etc. over other treated groups of rats. Overall, the dual drug-loaded NLCs outperformed over the plain drugs in terms of chemoprotection, implying superior therapeutic action and most significantly eliminating the hepatic toxicity induced by DEN in Wistar rat model.

Ellagic acid inhibits tumor growth and potentiates the therapeutic efficacy of sorafenib in hepatocellular carcinoma.

Project description:BackgroundSorafenib is a classic molecular targeted drug approved for hepatocellular carcinoma (HCC) therapy. However, a poor response rate and increasing resistance to sorafenib make its therapeutic efficacy suboptimal. Combination treatment with an agent capable of potentiating sorafenib sensitivity may be a promising solution.AimThe aim of this study was to determine the synergistic effect of ellagic acid (EA), a natural polyphenol, and sorafenib on HCC.MethodsCCK-8, EdU incorporation and colony formation assays were used to study the effect of EA on HCC cell proliferation. Apoptosis was detected by flow cytometry in HCC cells and TUNEL assay in xenograft tumors. Transcriptome analysis was utilized to investigate alterations in signaling pathways with EA treatment. A xenograft mouse model was used to confirm the synergistic effect of sorafenib and EA on HCC tumors in vivo.ResultsWe found that EA inhibited growth and induced apoptosis in both HCC cells and xenograft tumors. Mechanistically, EA treatment reduced the activation of the MAPK and Akt/mTOR signaling pathways in HCC cells. Furthermore, combined EA and sorafenib treatment further inhibited the MAPK and Akt/mTOR signaling pathways compared to EA or sorafenib alone. EA synergistically potentiated the anticancer activity of sorafenib against HCC both in vitro and in vivo.ConclusionEA inhibits HCC growth by inducing apoptosis through attenuation of the MAPK and Akt/mTOR signaling pathways. EA potentiates the response of HCC tumors to sorafenib both in vitro and in vivo, an effect that may be attributed to further inhibition of the MAPK and Akt/mTOR signaling pathways. These results suggest that EA is an effective adjuvant option for sorafenib therapy.

Enhanced anti-tumor therapy for hepatocellular carcinoma via sorafenib and KIAA1199-siRNA co-delivery liposomes.

Project description:Hepatocellular carcinoma (HCC) is one of the most lethal malignancies worldwide. Sorafenib (Sf) is currently the first-line treatment for HCC. However, due to the side effects and unsatisfied efficiency of Sf, it is urgent to combine different therapeutic agents to inhibit HCC progression and increase the therapeutic efficacy. Here, our study constructed a Sf and KIAA1199-siRNA co-loaded liposome Sf-Lp-KIAA, which was prepared by electrostatic interaction of KIAA1199-siRNA and Sf loaded liposome (Sf-Lp). The particle size, zeta potential, the in vitro cumulative release was investigated. The physical and chemical properties were characterized, and the inhibition of HepG2 growth and metastasis in vitro was investigated. The cellular uptake of the co-loaded liposome was significantly higher than that of free siRNA, and the drug/siRNA could be co-delivered to the target cells. Sf-Lp-KIAA could significantly inhibit the growth, migration, invasion and down-regulate KIAA1199 expression of HepG2 cells in vitro than that of single Sf treated group. In addition, the co-delivery liposome accumulated in the HepG2 subcutaneous tumor model and suppress tumor growth after systemic administration without induce obvious toxicity. The present study implied that the co-delivery of Sf and KIAA1199-siRNA through the co-loaded liposomes exerted synergistic antitumor effects on HCC, which would lay a foundation for HCC therapy in the future.

Antrodia cinnamomea boosts the anti-tumor activity of sorafenib in xenograft models of human hepatocellular carcinoma.

Project description:Hepatocellular carcinoma (HCC) has been recognized worldwide as one of the major causes of cancer death. The medicinal fungus Antrodia cinnamomea (A. cinnamomea) has been served as a functional food for liver protection. The aim of the present study was to investigate the potential activity of A. cinnamomea extracts as a safe booster for the anticancer activity of sorafenib, a multi-kinase inhibitor approved for the treatment of HCC. The biologically active triterpenoids in the ethanolic extracts of A. cinnamomea (EAC) were initially identified by HPLC/LC/MS then the different extracts and sorafenib were assessed in vitro and in vivo. EAC could effectively sensitize HCC cells to low doses of sorafenib, which was perceived via the ability of the combination to repress cell viability and to induce cell cycle arrest and apoptosis in HCC cells. The ability of EAC to enhance sorafenib activity was mediated through targeting mitogen-activated protein (MAP) kinases, modulating cyclin proteins expression and inhibiting cancer cell invasion. Moreover, the proposed combination significantly suppressed ectopic tumor growth in mice with high safety margins compared to single-agent treatment. Thus, this study highlights the advantage of combining EAC with sorafenib as a potential adjuvant therapeutic strategy against HCC.

Efficacy of sorafenib monotherapy versus sorafenib-based loco-regional treatments in advanced hepatocellular carcinoma.

Project description:BackgroundAlthough sorafenib is accepted as the standard of care in advanced hepatocellular carcinoma (HCC), its therapeutic benefit is marginal. Here, we aimed to compare the efficacy and safety of sorafenib monotherapy (S-M) and sorafenib-based loco-regional treatments (S-LRTs) in advanced HCC.MethodsFrom 2007 to 2012, 290 patients with advanced HCC (Barcelona Clinic Liver Cancer stage C) with S-M (n = 226) or S-LRTs (n = 64) were reviewed retrospectively. Survival outcomes and treatment-related toxicities between two groups were analyzed.ResultsVariables related to tumor burden and liver function were similar between the groups (all P > 0.05). Within the entire population, the S-LRTs group had both longer median overall survival (OS) (8.5 vs 5.5 months, P = 0.001) and progression-free survival (PFS) (5.3 vs 3.0 months, P = 0.002) than the S-M group. Furthermore, the S-LRTs group had longer Os than the S-M group in a subgroup with neither extrahepatic spread (EHS) nor regional nodal involvement (RNI) (18.0 vs 7.8 months, P = 0.019) and in a subgroup with EHS and/or RNI (8.3 vs 4.8 months, P = 0.028). In addition, the S-LRTs group had longer PFS than the S-M group in the subgroup with neither EHS nor RNI (9.6 vs 3.2 months, P = 0.027).TreatmentRelated toxicity was similar between two groups.ConclusionCombined use of sorafenib and LRTs may provide better treatment outcomes without significantly increasing treatment-related toxicities, even in patients with EHS and/or RNI. Therefore, addition of active LRTs might be considered, if feasible.

Synthesis and anti-hepatocellular carcinoma activity of aminopyridinol-sorafenib hybrids.

Project description:Sorafenib is recommended as the primary therapeutic drug for patients with hepatocellular carcinoma. To discover a new compound that avoids low response rates and toxic side effects that occur in sorafenib therapy, we designed and synthesized new hybrid compounds of sorafenib and 2,4,5-trimethylpyridin-3-ols. Compound 6 was selected as the best of 24 hybrids that inhibit each of the four Raf kinases. The anti-proliferative activity of 6 in HepG2, Hep3B, and Huh7 cell lines was slightly lower than that of sorafenib. However, in H6c7 and CCD841 normal epithelial cell lines, the cytotoxicity of 6 was much lower than that of sorafenib. In addition, similar to sorafenib, compound 6 inhibited spheroid forming ability of Hep3B cells in vitro and tumour growth in a xenograft tumour model of the chick chorioallantoic membrane implanted with Huh7 cells. Compound 6 may be a promising candidate targeting hepatocellular carcinoma with low toxic side effects on normal cells.
