Despite liver cancer being the second-leading cause of cancer-related death worldwide, few systemic drugs have been approved. Sorafenib, the first FDA-approved systemic drug for unresectable hepatocellular carcinoma (HCC), is limited by resistance. However, the precise mechanisms underlying this phenomenon are unknown. Since fibrinogen-like 1 (FGL1) is involved in HCC progression and upregulated after anticancer therapy, we investigated its role in regulating sorafenib resistance in HCC. FGL1 expression was assessed in six HCC cell lines (HepG2, Huh7, Hep3B, SNU387, SNU449, and SNU475) using western blotting. Correlations between FGL1 expression and sorafenib resistance were examined by cell viability, colony formation, and flow cytometry assays. FGL1 was knocked-down to confirm its effects on sorafenib resistance. FGL1 expression was higher in HepG2, Huh7, and Hep3B cells than in SNU387, SNU449, and SNU475 cells; high FGL1-expressing HCC cells showed a lower IC50 and higher sensitivity to sorafenib. In Huh7 and Hep3B cells, FGL1 knockdown significantly increased colony formation by 61% (p = 0.0013) and 99% (p = 0.0002), respectively, compared to that in controls and abolished sorafenib-induced suppression of colony formation, possibly by modulating ERK and autophagy signals. Our findings demonstrate that sorafenib resistance mediated by FGL1 in HCC cells, suggesting FGL1 as a potential sorafenib-resistance biomarker and target for HCC therapy.

Background: Hepatocellular carcinoma is one of the most common malignant tumors found all over the globe. Despite advances in surgery and chemotherapy, the five-year survival rate of patients with hepatocellular carcinoma is still low. It is known that the proliferation of hepatocellular carcinoma cells is closely related to the occurrence, development and prog- nosis of hepatocellular carcinoma. The present work investigates the expression of microRNA-489 (miR-489) in human hepatocellular carcinoma cells and its effect on the biological behavior of human hepatocellular carcinoma cells. Methods: The expression of miR-489 by fluorescence quantitative PCR detection in 30 patients with hepatoblastoma of liver cancer tissues and adjacent tissues was studied. Also, the determination of hepatoblastoma in four cell lines with differ- ent metastatic potential (HR8348, HCT116, HT29 and HEPG2) and the expression of miR-489 during miR-489 simulation process was studied. MTT assay, flow cytometry and Western blot analysis were performed to know the cell proliferation to detect the changes in cell cycle, apoptosis of cells, and SOX4 gene expression respectively. Results: RT-PCR results showed that the cells compared with pre-cancerous tissue, the expression level of miR-489 in hepatocellular carcinoma tissues than in adjacent tissue significantly decreased (P<0.05), and with liver cancer cell metastasis increased (P<0.05); analogue transfection constructed miR-489 overexpressing HEPG2 cell line by microRNA. MTT results showed that miR-489 can inhibit the proliferation of HEPG2 cells, the differences were statistically significant (P<0.05); flow cytometry results showed that miR-489 mimics was transfected into HEPG2 cells at 48 hours had no significant effect on cell cycle distribution (P > 0.05); but miR-489 expression could induce apoptosis, compared with the control group, the apoptosis of miR-489 mimics was significantly increased and the difference was statistically significant (P < 0.05). Conclusion: In conclusion, miR-489 can significantly inhibit the occurrence and development of hepatocellular carcinoma cells. The mechanism may be down regulated by the expression of SOX4 and inhibit cell proliferation. Further this study showed that the tumor cells SOX4 gene as a regulatory factor target the genes of miR-489 in hepatocellular carcinoma. Keywords: Hepatocellular carcinoma; mircroRNA-489; SOX4; apoptosis.

Abstract Background: Drug resistance is still a major obstacle during the cisplatin-based chemotherapy of hepatocellular carcinoma (HCC). Recently, studies have indicated that the population of CD133+ cancer cells is partially responsible for the failure of cancer treatment. However, the potential mechanisms are still unclear.Methods: CD133+ HepG2 and Huh7 cells were sorted via flow cytometry. CCK-8 assay was used to detect the cytotoxicity of cisplatin and silibinin against HCC cells. Western blot assay was performed to detect the protein expression, cleavage of caspases and release of cytochrome c from mitochondria into cytosol. Flow cytometry analysis was used to measure the apoptotic rate of CD133+ HepG2 and Huh7 cells.Results: CD133+ HepG2 and Huh7 cells were observed to exhibit obvious resistance against cisplatin. However, co-treatment with silibinin significantly reduced the cisplatin resistance of CD133+ HepG2 and Huh7 cells. Furthermore, although CD133+ HepG2 and Huh7 cells were resistant to cisplatin-induced apoptosis, co-treatment with silibinin enhanced the cisplatin-induced apoptosis through promoting the release of cytochrome c from mitochondria into cytosol. In the mechanism research, we proved that silibinin inhibited the expression of OPA1 in CD133+ HepG2 and Huh7 cells. Under the stress of cisplatin, silibinin promoted the collapse of mitochondria and increased the release of cytochrome c. As a result, caspases-dependent apoptosis was induced in CD133+ HepG2 and Huh7 cells which were co-treated with cisplatin and silibinin.Conclusion: Silibinin sensitizes CD133+ HCC cells to cisplatin-induced apoptosis through suppression of OPA1.

Sufentanil is a powerful analgesic that acts on μ-receptors, but there are few studies on sufentanil in cancer. The biological function and underlying mechanisms of sufentanil on the hepatocellular carcinoma (HCC) cells were explored in the present study. HCC cells were first treated with different concentrations of sufentanil and the most optimum concentration of sufentanil was determined. The expression of miR-204 in HCC cells was changed by transfected with miR-204 inhibitor and the transfection efficiency was assessed by qRT-PCR. CCK-8, wound-healing and Transwell assays were performed to evaluate the proliferation, migration and invasion of HCC cells, respectively. The level of AKT and PI3K phosphorylation (p-AKT and p-PI3K) were assessed by western blot analysis. Our results demonstrated that sufentanil effectively inhibited cell proliferation,migration and invasion in both Huh7 and Hep3B cells, and significantly decreased the expression of p-AKT and p-PI3K. In addition, miR-204 was upregulated in Huh7 and Hep3B cells treated with sufentanil, and low expression of miR-204 attenuated the damage of sufentanil on the viability of Huh7 and Hep3B cells. Taken together, sufentanil suppressed the proliferation, migration and invasion of HCC cells via inhibiting AKT/PI3K signaling pathway by targeting miR-204.

We previously demonstrated that anthocyanins from the fruits of Vitis coignetiae Pulliat (AIMs) induced the apoptosis of hepatocellular carcinoma cells. However, many researchers argued that the concentrations of AIMs were too high for in vivo experiments. Therefore, we performed in vitro at lower concentrations and in vivo experiments for the anti-cancer effects of AIMs. AIMs inhibited the cell proliferation of Hep3B cells in a dose-dependent manner with a maximum concentration of 100 µg/mL. AIMs also inhibited the invasion and migration at 100 µg/mL concentration with or without the presence of TNF-α. To establish the relevance between the in vitro and in vivo results, we validated their effects in a Xenograft model of Hep3B human hepatocellular carcinoma cells. In the in vivo test, AIMs inhibited the tumorigenicity of Hep3B cells in the xenograft mouse model without showing any clinical signs of toxicity or any changes in the body weight of mice. AIMs inhibited the activation NF-κB and suppressed the NF-κB-regulated proteins, intra-tumoral microvessel density (IMVD) and the Ki67 activity of Hep3B xenograft tumors in athymic nude mice. In conclusion, this study indicates that AIMs have anti-cancer effects (inhibition of proliferation, invasion, and angiogenesis) on human hepatocellular carcinoma xenograft through the inhibition of NF-κB and its target protein.

Mutant p53 (R248Q) induces doxorubicin (ADM) resistance in hepatocellular carcinoma (HCC). Dihydroartemisinin (DHA) can synergistically enhance anticancer effect of many chemotherapeutic agents. However, whether DHA could increase therapeutic efficacy of ADM in p53 (R248Q)-expressing HCC cells remains unknown. In the present study, we established mutant p53 (R248Q)-expressing Hep3B cells to study the effect and mechanism of DHA on ADM resistance and the synergistic effect of DHA with ADM. We found that P-gp was highly expressed in p53 (R248Q)-expressing Hep3B cells. As a result, cells expressing p53 (R248Q) displayed higher cell viability and lower cell apoptosis level upon ADM treatment. Meanwhile, phosphorylation levels of ERK1/2 and p65 were elevated in p53 (R248Q)-expressing Hep3B cells. However, combination of DHA and ADM treatment decreased cell viability and elevated cell apoptosis level in p53 (R248Q)-expressing Hep3B cells. Molecular dynamics simulations showed that DHA had the potential to bind with mutant p53 (R248Q) protein. Furthermore, DHA treatment decreased P-gp expression and inhibited phosphorylation levels of ERK1/2 and p65 in p53 (R248Q)-expressing Hep3B cells. Finally, DHA treatment could significantly reduce ADM efflux in p53 (R248Q)-expressing cells. Our results indicate that DHA could decrease P-gp expression via inhibiting the p53 (R248Q)-ERK1/2-NF-κB signaling pathway, which eventually confers sensitization of p53 (R248Q)-expressing HCC cells to ADM. Our study provides evidence for the potential application of DHA and ADM combination in treatment of mutant p53 (R248Q)-harbored HCC.

<p class="Abstract">The objective of the present study was to investigate the anti-cancer effects of eriodictyol in human hepatocellular carcinoma cells (Hep-G2) and normal liver hepatocyte cell line (AML12) along with evaluating its mode of action. Sulforhodamine B assay was used to evaluate the cytotoxic effect of the compound while as fluorescence microscopy was involved to demonstrate the effect of eriodictyol on cellular apoptosis. Flow cytometry was used to investigate the effect of eriodictyol on cell cycle while Western blot analysis revealed the effect on apoptosis-related protein expressions. Results indicate that eriodictyol-induced selective and concentration-dependent cytotoxic effect on Hep-G2 cancer cells while AML12 normal liver cells were very less susceptible to its effect. Eriodictyol-induced apoptosis related morphological changes including chromatin condensation and nuclear fragmentation. It also induced G2/M cell cycle arrest in these cells. Eriodictyol led to up-regulation of Bax and PARP and down-regulation of Bcl-2 protein.</p><p><strong>Video Clip</strong></p><a href="https://youtube.com/v/MJwBotwrgWM">Flow cytometry assay</a>: 35 sec<p> </p>
