A New Option for the Treatment of Intrahepatic Cholangiocarcinoma: Percutaneous Hepatic Perfusion with CHEMOSAT Delivery System. Cells 2021; 10:E70.

Abstract
Liver metastases are a major management problem; since they occur in tumors of different origin, they are often multiple, difficult to visualize and can lie dormant for many years. Patients with liver metastases usually die of their disease, mostly due to liver failure, since systemic treatments are unable to eradicate micro-metastasis, and interventional loco-regional procedures cannot treat all existing ones. Cholangiocarcinoma (CCA) is the second most common primary liver tumor, showing a poor overall prognosis. When resection is not possible, treatment options include tumor-focused or local ablative therapy, organ-focused or regional therapy and systemic therapy. We reviewed available loco-regional therapeutic options, with particular focus on the CHEMOSAT® Melphalan/Hepatic Delivery System (CS-HDS), which is uniquely positioned to perform a percutaneous hepatic perfusion (PHP), in order to treat the entire liver as a standalone or as complementary therapy. This system isolates the liver circulation, delivers a high concentration of chemotherapy (melphalan), filters most chemotherapy out of the blood and is a repeatable procedure. Most CS-HDS benefits are demonstrated in liver-predominant diseases, like liver metastasis from uveal melanoma (UM), hepatocarcinoma (HCC) and CCA. More than 650 procedures have been performed in Europe to date, mostly to treat liver metastases from UM. In CCA, experience is still limited, but retrospective analyses have been reported, while phase II and III studies are closed, waiting for results or ongoing.

Abstract
We have systematically investigated the humidity sensing performance and cytotoxic activity of TiO2 nanoflowers synthesized by hydrothermal method. Our result reveals that TiO2 nanoflower based sensor devices show good performance at room temperature with a maximum sensitivity of ∼815% along with a response time of ∼143 s and a recovery time of ∼33 s. Our findings also evaluate the cytotoxic effect of TiO2 nanoflowers on human HepG2 cell lines. The cells are cultured in DMEM medium with varying concentrations of TiO2 nanoflowers for 24, 48 and 72 hours respectively. The results indicate that TiO2 nanoflower doses time dependently suppress the proliferation of HepG2 cell lines.

Abstract
Cluster of differentiation (CD)133 is considered a molecular marker of cancer stem cells in hepatocellular carcinoma. In the present study, the effect of lidamycin (LDM) on CD133 expression in hepatocellular carcinoma (Huh7 cells) was evaluated and the potential molecular mechanism was investigated. Flow cytometry analysis, as well as sorting, sphere formation and western-blot assays, were performed in vitro to explore the effects of LDM on CD133 expression. A subcutaneous tumor model in nude mice was used to observe the effects of LDM on tumor volume and CD133 protein in vivo. To investigate the potential underlying molecular mechanism, Notch signaling pathway activity was detected by western blot analysis and reverse transcription-quantitative polymerase chain reaction. The proportion of CD133+ cells and the expression of CD133 protein were revealed to be downregulated by LDM. Sphere formation of sorted CD133+ cells was suppressed 7 days after LDM treatment. In addition, LDM inhibited tumor volume formed from sorted CD133+ cells and CD133 protein level in vivo. LDM decreased the mRNA level of NOTCH1, Hes1 (Hes family BHLH transcription factor 1) and Hey1 (Hes-related family BHLH transcription factor with YRPW motif 1) genes; consequently, the protein expression of NOTCH1, Notch intracellular domain, Hes1 and Hey1 was decreased by LDM. Downregulation of the Notch signaling pathway by LDM was enhanced through combination with N-[N-(3,5-difluorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl ester. In brief, these data suggest that LDM suppresses CD133 expression via the Notch signaling pathway, indicating the potential mechanism of LDM on CD133 and the benefits for further clinical application.

Abstract
The lysosome inhibitors bafilomycin A1 and chloroquine have both lysosomotropic properties and autophagy inhibition ability, and are promising clinical agents to be used in combination with anticancer drugs. In order to investigate this combination effect, HepG2 cells were treated with bafilomycin A1, chloroquine, or/and doxorubicin, and their proliferative ability, induction of apoptosis, and the changes of lysosomal membrane permeabilization and mitochondrial membrane potential were studied. The results demonstrate that treatment with bafilomycin A1 or chloroquine alone at a relatively low concentration promotes the inhibitory effect of doxorubicin on cell growth and apoptosis. Further studies reveal that bafilomycin A1 and chloroquine promote lysosomal membrane permeabilization and the reduction of mitochondrial membrane potential induced by doxorubicin. Our findings suggest that bafilomycin A1 and chloroquine potentiate the anticancer effect of doxorubicin in hepatic cancer cells and that supplementation of conventional chemotherapy with lysosome inhibitors may provide a more efficient anticancer therapy.

Abstract
Hepatic stellate cells (HSCs) that are activated by human hepatocellular carcinoma (HCC) cells secrete a variety of cytokines, which are the main component of the HCC microenvironment. We aimed to determine whether 8-bromo-7-methoxychrysin (BrMC) could interfere in cross-talk of the human hepatic stellate cell line LX-2 and liver cancer stem-like cells (LCSLCs) to inhibit the characteristics of LCSLCs endowed with the capacity of sustaining human hepatocellular carcinoma (HCC) self-renewal and progression, and to identify its potential mechanism of action. We found that the levels of fibroblast activation protein (FAP) were augmented in LX-2 cells treated with the conditioned medium of LCSLCs (LCSLC-CM) compared to those cultured with routine medium, indicating that the LCSLC-CM can activate LX-2 cells to become liver cancer-associated stellate cells (LCAHSCs). Furthermore, sphere forming capability of SMMC-7721 cells was enhanced and stem cell-related protein expression was significantly increased following treatment with the conditioned medium of LCAHSCs (LCAHSC-CM). Moreover, the level of p-STAT3 was increased in LX-2 cells treated with LCSLC-CM and BrMC reduced expression of p-STAT3. Combination of BrMC and the selective inhibitor of STAT3 cucurbitacin I (JSI-124) synergistically suppressed the LCSLC characteristics in SMMC-7721 cells. Collectively, our data showed that BrMC inhibited the interaction between LX-2 cells and HCC-derived CSCs, and did so potentially through modulation of the STAT3 pathway. Future therapeutic strategies employing anti-CSC therapy should confirm the potential of cucurbitacin I (JSI-124) and BrMC as potent therapeutic agents.

Abstract
This work aims to evaluate the impact of 2-morpholino-8-phenyl-4H-chromen-4-one (LY294002) combined 5-fluorouracil (5-FU) for the activity of CD90+ liver cancer cells derived from the human liver cancer cell line MHCC97H. MHCC97H sphere-forming cells (MSFCs) were amplified in serum-free medium and CD90+ cells were isolated from bulk MSFCs using flow cytometry. The phenotype of these CD90+ cells which show liver cancer stem cells (LCSCs) behavior was validated in vitro and in a xenograft model in nude mice. MSFCs, CD90+ liver cancer cells (CD90+ LCCs), and parental MHCC97H cells were treated with no drug, LY294002 alone, 5-FU alone, or both drugs together and then compared in terms of stem cell-related gene expression, proliferation, and invasion. Stem cell phenotype increased with increasing proportion of CD90+ cells, in ascending order: parental MHCC97H cells, MSFCs, and CD90+ liver cancer cells. LY294002 reduced the expression of CD90, Nanog, SALL4, and SHP2 in a concentration-dependent manner in CD90+ LCCs and MSFCs, but not in parental cells. LY294002 blocked AKT phosphorylation via the PI3K/AKT signaling pathway and inhibited CD90+ LCCs proliferation and tumorigenicity in vitro and in vivo. CD90+ liver cancer cells can express liver cancer stem cell phenotype. LY294002 inhibits the proliferation and invasion of MHCC97H-derived CD90+ LCCs and sensitized CD90+ LCCs-derived tumors to 5-FU in the current study which may provide insight into the association between the LY294002 combined 5-FU and liver cancer stem cell (LCSCs).

Abstract
Hepatic angiosarcoma (HAS) is rare but often fatal. A review of literature in 1979 found that only 3% of the 70 patients lived for more than 2 years, but the survival might have been improved over the years. We conducted a retrospective study and reviewed the medical records of patients who visited a teaching hospital in Taiwan from January 2000 to August 2010 and had pathological proof of HAS. In addition, we conducted a review of literature and compared those who survived for 2 years or more to those who did not. Of the 3503 patients with primary liver cancer we identified, 9 had HAS, of whom 3 (33.3%) survived for 2 years or more. One survived for 24 months without surgical resection, and the other two received surgery with postoperative chemotherapy and were still alive 32 and 37 months later, respectively. Through reviewing literature, we identified 3 more patients in Taiwan who had survived for 2 years or more. One survived for 42 months without surgical resection, the other two received segmentectomy with postoperative chemotherapy or radiotherapy. We also identified 8 such cases outside Taiwan, including 1 who received chemotherapy without surgery and survived for 53 months. None of the differences in the clinical characteristics between those who had and had not survived for 2 years or more reached statistical significance. In conclusion, we believe the combination of surgery and adjuvant chemotherapy may be able to achieve long-term survival in some HAS patients nowadays, and it is even possible to achieve fair survival using chemotherapy alone.

Abstract
The study investigated the growth-inhibiting and apoptosis mediating effects of B. serrata extract as monotherapy and combination therapy with DOX against hepatocellular carcinoma cell lines. Boswellic acid rich fraction of B. serrata extract was prepared. MTT assay on HepG2 and Hep3B cells was carried out using B. serrata alone and in combination with DOX. Further, caspase-3 activity, TNF-α level, and IL-6 level were estimated. Isobolographic analysis was carried out to evaluate the effect of combination therapy. Additionally, protective effect of B. serrata extract on DOX induced hepatic toxicity was also evaluated in Wistar rats. B. serrata extract inhibited growth of HepG2 (IC50 value of 21.21 ± 0.92 μg/mL) as well as HepG2 (IC50 value of 18.65 ± 0.71 μg/mL). DOX inhibited growth in HepG2 and Hep3B cells with an IC50 of 1.06 ± 0.04 μg/mL and 1.92 ± 0.09 μg/mL. Isobolographic analysis showed combination index (CI) of DOX and B. serrata extract of 0.53 ± 0.03 to 0.79 ± 0.02 suggesting synergistic behavior against the two cell lines. B. serrata extract also caused dose dependent increase in caspase-3 activity, TNF-α level, and IL-6 level which was higher (P < 0.001) with DOX (1 μM) and B. serrata extract (20 μg/mL) combination. B. serrata extract also protected Wistar rats against DOX induced hepatic toxicity.

Abstract
AIM: To evaluate whether 8-bromo-7-methoxychrysin (BrMC), a synthetic analogue of chrysin, inhibits the properties of cancer stem cells derived from the human liver cancer MHCC97 cell line and to determine the potential mechanisms.
METHODS: CD133+ cells were sorted from the MHCC97 cell line by magnetic activated cell sorting, and amplified in stem cell-conditioned medium to obtain the enriched CD133+ sphere forming cells (SFCs). The stem cell properties of CD133+ SFCs were validated by the tumorsphere formation assay in vitro and the xenograft nude mouse model in vivo, and termed liver cancer stem cells (LCSCs). The effects of BrMC on LCSCs in vitro were evaluated by MTT assay, tumorsphere formation assay and transwell chamber assay. The effects of BrMC on LCSCs in vivo were determined using a primary and secondary xenograft model in Balb/c-nu mice. Expressions of the stem cell markers, epithelial-mesenchymal transition (EMT) markers and β-catenin protein were analyzed by western blotting or immunohistochemical analysis.
RESULTS: CD133+ SFCs exhibited stem-like cell properties of tumorsphere formation and tumorigenesis capacity in contrast to the parental MHCC97 cells. We found that BrMC preferentially inhibited proliferation and self-renewal of LCSCs (P < 0.05). Furthermore, BrMC significantly suppressed EMT and invasion of LCSCs. Moreover, BrMC could efficaciously eliminate LCSCs in vivo. Interestingly, we showed that BrMC decreased the expression of β-catenin in LCSCs. Silencing of β-catenin by small interfering RNA could synergize the inhibition of self-renewal of LCSCs induced by BrMC, while Wnt3a treatment antagonized the inhibitory effects of BrMC.
CONCLUSION: BrMC can inhibit the functions and characteristics of LCSCs derived from the liver cancer MHCC97 cell line through downregulation of β-catenin expression.

Interventionally implanted port catheter systems for hepatic arterial infusion of chemotherapy in patients with primary liver cancer: a phase II-study (NCT00356161). BMC Gastroenterol 2013; 13:125.

Abstract
BACKGROUND Hepatic arterial infusion (HAI) of chemotherapy requires the implantation of a transcatheter application system which is traditionally performed by surgery. This procedure, but particularly the adjacent drug application via pump or port is often hampered by specific complications and device failure. Interventionally implanted port catheter systems (IIPCS) facilitate the commencement of HAI without need for laparatomy, and are associated with favorable complication rates. We here present an evaluation of the most important technical endpoints associated with the use of IIPCS for HAI in patients with primary liver cancers. METHODS 70 patients (pts) with hepatocellular (HCC, n=33) and biliary tract cancer (BTC, n=37) were enrolled into a phase II -study. Of those, n=43 had recurrent disease and n=31 suffered from liver-predominant UICC-stage IVb. All pts were provided with IIPCSs before being treated with biweekly, intraarterial chemotherapy (oxaliplatin, 5-Flourouracil, folinic acid). The primary objective of the trial was defined as evaluation of device-related complications and port duration. RESULTS Implantation of port catheters was successful in all patients. Mean treatment duration was 5.8 months, and median duration of port patency was not reached. Disease-progression was the most common reason for treatment discontinuation (44 pts., 63%), followed by chemotherapy-related toxicity (12 pts., 17%), and irreversible device failure (5 pts., 7%). A total of 28 port complications occurred in 21 pts (30%). No unexpected complications were observed. CONCLUSIONS HAI via interventionally implanted port catheters can be safely applied to patients with primary liver tumors far advanced or/and pretreated.

Abstract
Hepatocellular carcinoma (HCC) remains a major public health problem. Transarterial chemoembolization (TACE) is recognized as the standard of care for patients with unresectable, asymptomatic, noninvasive and multinodular HCC. This procedure is based on percutaneous administration of a cytotoxic drug emulsified with Lipiodol followed by embolization of the tumour-feeding arteries. The standard procedure involves Lipiodol, an oily contrast medium which consists of a mixture of long-chain di-iodinated ethyl esters of poppy seed fatty acids. The aim of this review is to discuss the physical properties, tumour uptake behaviour and drug delivery effects of Lipiodol, the parameters influencing tumour uptake and future prospects. Lipiodol has a unique place in TACE as it combines three specific characteristics: drug delivery, transient and plastic embolization and radiopacity properties. Substantial heterogeneity in the physicochemical characteristics of Lipiodol/cytotoxic agent emulsions might reduce the efficacy of this procedure and justifies the current interest in Lipiodol for drug delivery.

Lidamycin inhibits tumor initiating cells of hepatocellular carcinoma Huh7 through GSK3β/β-catenin pathway. Mol Carcinog 2013; 54:1-8.

Abstract
Recently, tumor initiating cells are considered as the central role of tumorigenicity in hepatocellular carcinoma. Enediyne anticancer antibiotic lidamycin with great potential antitumor activity is currently evaluated in Phase II clinical trials. In this study, we evaluated the effect of lidamycin on tumor initiating cells of hepatocellular carcinoma Huh7 and identified the potential mechanism. Flow cytometry analysis and sorting assay, surface marker assay, sphere formation assay, and aldefluor assay were used to evaluate the effect of lidamycin on Huh7 tumor initiating cells in vitro. To investigate the potential mechanism, the activity of GSK3β/β-catenin pathway was detected by Western blot and T cell factors transcriptional activity assay. Subcutaneous tumor model in nude mice was used to observe in vivo effect of lidamycin on Huh7 cells. Lidamycin decreased the proportion of EpCAM+ cells and the expression of EpCAM protein. Lidamycin inhibited sphere formation of sorted EpCAM+ cells in 7 d, and of parental cells in three serial passages. The population of aldehyde dehydrogenase-positive cells was reduced by lidamycin. In addition, lidamycin restrained tumor volume and incidence in vivo. Lidamycin activated GSK3β, and degraded the activity of β-catenin. Consequently, transcriptional activity of β-catenin/T cell factors was decreased. In brief, these results suggest that lidamycin suppressed Huh7 tumor initiating cells via GSK3β/β-catenin pathway. These findings reveal the potential mechanism of lidamycin on tumor initiating cells and the benefit for further clinical evaluation.

Abstract
OBJECTIVE Everolimus, an inhibitor of the mammalian target of rapamycin, has recently demonstrated efficacy and safety in a Phase III, double-blind, randomized trial (RADIANT-3) in 410 patients with low- or intermediate-grade advanced pancreatic neuroendocrine tumours. Everolimus 10 mg/day provided a 2.4-fold improvement compared with placebo in progression-free survival, representing a 65% risk reduction for progression. The purpose of this analysis was to investigate the efficacy and safety of everolimus in the Japanese subgroup enrolled in the RADIANT-3 study. METHODS Subgroup analysis of the Japanese patients was performed comparing efficacy and safety between everolimus 10 mg/day orally (n = 23) and matching placebo (n = 17). The primary endpoint was progression-free survival. Safety was evaluated on the basis of the incidence of adverse drug reactions. RESULTS Progression-free survival was significantly prolonged with everolimus compared with placebo. The median progression-free survival was 19.45 months (95% confidence interval, 8.31-not available) with everolimus vs 2.83 months (95% confidence interval, 2.46-8.34) with placebo, resulting in an 81% risk reduction in progression (hazard ratio, 0.19; 95% confidence interval, 0.08-0.48; P< 0.001). Adverse drug reactions occurred in all 23 (100%) Japanese patients receiving everolimus and in 13 (77%) patients receiving placebo; most were grade 1/2 in severity. The most common adverse drug reactions in the everolimus group were rash (n = 20; 87%), stomatitis (n = 17; 74%), infections (n = 15; 65%), nail disorders (n = 12; 52%), epistaxis (n = 10; 44%) and pneumonitis (n = 10; 44%). CONCLUSIONS These results support the use of everolimus as a valuable treatment option for Japanese patients with advanced pancreatic neuroendocrine tumours.

Int J Biol Sci 2012; 8:992-1004.

Abstract
Background: EpCAM or CD133 has been used as the tumor initiating cells (TICs) marker in hepatocellular carcinoma (HCC). We investigated whether cells expressing with both EpCAM and CD133 surface marker were more representative for TICs in hepatocellular carcinoma Huh7 cells. Methods: Four different phenotypes of CD133+EpCAM+, CD133+EpCAM-, CD133-EpCAM+ and CD133-EpCAM- in Huh7 cells were sorted by flow cytometry. Then cell differentiation, self-renewal, drug-resistance, spheroid formation and the levels of stem cell-related genes were detected to compare the characteristics of TICs. The ability of tumorigenicity was measured in nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice to verify TICs. Results: CD133+EpCAM+ cells have many characteristics of TICs in Huh7 cells compared with CD133+EpCAM-, CD133-EpCAM+, CD133-EpCAM- cells, including enrichment in side population cells, higher differentiation capacity, increased colony-formation ability, preferential expression of stem cell-related genes, appearance of drug-resistant to some chemotherapeutics, more spheroid formation of culture cells and stronger tumorigenicity in NOD/SCID mice. Conclusion: CD133+EpCAM+ phenotype is precisely represented TICs in Huh7 cells. It might be useful for studying biology mechanism of TICs in hepatocellular carcinoma and screening new targets for cancer therapy.
