Iron deficiency in hepatocellular carcinoma cells induced sorafenib resistance by upregulating HIF-1α to inhibit apoptosis. Biomed Pharmacother 2023; 163:114750. [PMID: 37087978 DOI: 10.1016/j.biopha.2023.114750] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 04/12/2023] [Accepted: 04/20/2023] [Indexed: 04/25/2023] Open
Abstract
Sorafenib is the first-line therapeutic agent for hepatocellular carcinoma (HCC), but the drug resistance has become a major impediment. Previously we found that the abnormal iron metabolism in HCC led to iron deficiency, whether it induces sorafenib resistance during the treatment of HCC is not yet disclosed. In this study, we observed the effects of iron deficiency on sorafenib resistance and explored the underlying mechanisms. The results revealed that the killing effects of sorafenib on HCC cells were weakened by iron deficiency but effectively restored by iron re-supplementation. The ferroptosis indicators, including the contents of lipid hydroperoxide (LPO) and malondialdehyde (MDA), the level of intracellular reactive oxygen species (ROS), and the expression of glutathione peroxidase 4 (GPX4), were not significantly changed by iron deficiency in sorafenib-treated HCC cells. However, the sorafenib-induced apoptosis of HCC cells was inhibited by iron deficiency. Notably, the expression of anti-apoptotic protein B-cell lymphoma-2 (BCL-2) was elevated, and the expressions of other apoptotic proteins, BCL2-associated X (Bax), caspase-3, and caspase-9, were inhibited by iron deficiency. Mechanistically, iron deficiency upregulated hypoxia-inducible factor 1 alpha (HIF-1α) to increase BCL-2. Inhibition of HIF-1α suppressed the iron deficiency-induced BCL-2 and sorafenib resistance. In summary, iron deficiency in HCC cells generated sorafenib resistance by increasing HIF-1α and BCL-2, which therefore inhibited the sorafenib-induced apoptosis of HCC cells. These results identified iron deficiency as a new factor of sorafenib resistance in HCC cells, which would be an effective target to alleviate sorafenib resistance.

KLF14 regulates the growth of hepatocellular carcinoma cells via its modulation of iron homeostasis through the repression of iron-responsive element-binding protein 2. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2023; 42:5. [PMID: 36600258 DOI: 10.1186/s13046-022-02562-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Accepted: 12/06/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a multifactor-driven malignant tumor with rapid progression, which causes the difficulty to substantially improve the prognosis of HCC. Limited understanding of the mechanisms in HCC impedes the development of efficacious therapies. Despite Krüpple-Like factors (KLFs) were reported to be participated in HCC pathogenesis, the function of KLF14 in HCC remains largely unexplored. METHODS We generated KLF14 overexpressed and silenced liver cancer cells, and nude mouse xenograft models for the in vitro and in vivo study. Luciferase reporter assay, ChIP-qPCR, Co-IP, immunofluorescence were performed for mechanism research. The expression of KLF14 in HCC samples was analyzed by quantitative RT-PCR, Western blotting, and immunohistochemistry (IHC) analysis. RESULTS KLF14 was significantly downregulated in human HCC tissues, which was highly correlated with poor prognosis. Inhibition of KLF14 promoted liver cancer cells proliferation and overexpression of KLF14 suppressed cells growth. KLF14 exerts its anti-tumor function by inhibiting Iron-responsive element-binding protein 2 (IRP2), which then causes transferrin receptor-1(TfR1) downregulation and ferritin upregulation on the basis of IRP-IREs system. This then leading to cellular iron deficiency and HCC cells growth suppression in vitro and in vivo. Interestingly, KLF14 suppressed the transcription of IRP2 via recruiting SIRT1 to reduce the histone acetylation of the IRP2 promoter, resulting in iron depletion and cell growth suppression. More important, we found fluphenazine is an activator of KLF14, inhibiting HCC cells growth through inducing iron deficiency. CONCLUSION KLF14 acts as a tumor suppressor which inhibits the proliferation of HCC cells by modulating cellular iron metabolism via the repression of IRP2. We identified Fluphenazine, as an activator of KLF14, could be a potential compound for HCC therapy. Our findings therefore provide an innovative insight into the pathogenesis of HCC and a promising therapeutic target.

Biomed Pharmacother 2022; 153:113363. [PMID: 35834989 DOI: 10.1016/j.biopha.2022.113363] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 06/18/2022] [Accepted: 06/28/2022] [Indexed: 11/27/2022] Open
Abstract
OBJECTIVE The improvements of antitumor effects and tolerability on chemotherapy for advanced hepatocellular carcinoma (HCC) are warranted. Here, we aimed to elucidate the mechanism of the combining effect of tyrosine kinase inhibitor sorafenib (SOR) and iron chelator deferasirox (DFX) in human hepatoma cell lines, HepG2 and Huh-7. METHODS The types of programmed cell deaths (PCDs); necrosis/necroptosis and apoptosis, were evaluated by flow cytometry and fluorescent microscopy. Human cleaved caspase-3 was analyzed by ELISA for apoptosis. GSH assay was used for ferroptosis. PCDs inhibition was analyzed by adding apoptosis inhibitor Z-VAD-FMK, ferroptosis inhibitor ferrostatin-1, necroptosis inhibitor necrosulfonamide, respectively. The expression of NF-κB was quantified by Western blotting. RESULTS In SOR monotherapy, cleaved caspase-3 expression was increased in all concentrations, confirming the result that SOR induces apoptosis. In SOR monotherapy, GSH/GSSG ratio was decreased on concentration-dependent, showing that SOR also induced ferroptosis. Lipid Peroxidation caused by SOR, corresponding to ferroptosis, was suppressed by DFX. In fluorescence microscopy of SOR monotherapy, apoptosis was observed at a constant rate on all concentrations, while necroptosis and ferroptosis were increased on high concentration. In sorafenib and deferasirox combinations, sub G1 phase increased additively. In SOR and DFX combinations, the cytotoxic effects were not suppressed by ferrostatin-1, but suppressed by Z-VAD-FMK and necrosulfonamide. In each monotherapy, and SOR + DFX combinations, the expression of NF-κB in nucleus was suppressed. Regarding PCD by SOR and DFX combination, ferroptosis was suppressed and both apoptosis and necroptosis became dominant. CONCLUSION Suppression of NF-κB is possibly involved in the effect of DFX. As a result, SOR and DFX combination showed additive antitumor effects for HCC through the mechanism of programed cell deaths and NF-kB signal modification.

Abstract
BACKGROUND Osteosarcoma is an aggressive bone tumor. It represents the principal cause of cancer-associated death in children. Considering the recent findings on the role of iron in cancer, iron chelation has been investigated for its antineoplastic properties in many tumors. Deferasirox is the most used iron chelator compound and in previous studies showed an anticancer effect in hematologic and solid malignancies. Eltrombopag is a Thrombopoietin receptor used in thrombocytopenia that also binds and mobilize iron. It demonstrated an effect on iron overload conditions and also in contrasting cancer cell proliferation. OBJECTIVE We analyzed the effects of deferasirox and eltrombopag in human osteosarcoma cells in an attempt to identify other therapeutic approaches for this tumor. METHODS We cultured and treated with deferasirox and Eltrombopag, alone and in combination, two human osteosarcoma cell lines, MG63 and 143B. After 72h exposure, we performed RTqPCR, Western Blotting, Iron Assay and cytofluorimetric assays to evaluate the effect on viability, apoptosis, cell cycle progression and ROS production. RESULTS The iron-chelating properties of the two compounds are also confirmed in osteosarcoma, but we did not observe any direct effect on tumor progression. DISCUSSION We tested deferasirox and eltrombopag, alone and in combination, in human osteosarcoma cells for the first time and demonstrated that their iron-chelating activity does not influence biochemical pathways related to cancer progression and maintenance. CONCLUSION Although further investigations on possible effects mediated by cells of the tumor microenvironment could be of great interest, in vitro iron chelation in osteosarcoma does not impair tumor progression.

Abstract
BACKGROUND Iron is required for cellular metabolism, and rapidly proliferating cancer cells require more of this essential nutrient. Therefore, iron regulation may well represent a new avenue for cancer therapy. We have reported, through in vitro and in vivo research involving pancreatic cancer cell lines, that the internal-use, next-generation iron chelator deferasirox (DFX) exhibits concentration-dependent tumour-suppressive effects, among other effects. After performing a microarray analysis on the tumour grafts used in that research, we found that DFX may be able to suppress the cellular movement pathways of pancreatic cancer cells. In this study, we conducted in vitro analyses to evaluate the effects of DFX on the invasive and migratory abilities of pancreatic cancer cells. METHODS We used pancreatic cancer cell lines (BxPC-3, Panc-1, and HPAF II) to examine the efficacy of DFX in preventing invasion in vitro, evaluated using scratch assays and Boyden chamber assays. In an effort to understand the mechanism of action whereby DFX suppresses tumour invasion and migration, we performed G-LISA to examine the activation of Cdc42 and Rac1 which are known for their involvement in cellular movement pathways. RESULTS In our scratch assays, we observed that DFX-treated cells had significantly reduced invasive ability compared with that of control cells. Similarly, in our Boyden chamber assays, we observed that DFX-treated cells had significantly reduced migratory ability. After analysis of the Rho family of proteins, we observed a significant reduction in the activation of Cdc42 and Rac1 in DFX-treated cells. CONCLUSIONS DFX can suppress the motility of cancer cells by reducing Cdc42 and Rac1 activation. Pancreatic cancers often have metastatic lesions, which means that use of DFX will suppress not only tumour proliferation but also tumour invasion, and we expect that this will lead to improved prognoses.

Abstract
Iron is implicated in the pathogenesis of a number of human liver diseases. Hereditary hemochromatosis is the classical example of a liver disease caused by iron, but iron is commonly believed to contribute to the progression of other forms of chronic liver disease such as hepatitis C infection and nonalcoholic fatty liver disease. In this review, we present data from cell culture experiments, animal models, and clinical studies that address the hepatotoxicity of iron. These data demonstrate that iron overload is only weakly fibrogenic in animal models and rarely causes serious liver damage in humans, calling into question the concept that iron overload is an important cause of hepatotoxicity. In situations where iron is pathogenic, iron-induced liver damage may be potentiated by coexisting inflammation, with the resulting hepatocyte necrosis an important factor driving the fibrogenic response. Based on the foregoing evidence that iron is less hepatotoxic than is generally assumed, claims that assign a causal role to iron in liver injury in either animal models or human liver disease should be carefully evaluated.

Abstract
Objectives Iron is an essential element for cell proliferation and growth processes. We have reported that deferasirox (DFX), an oral iron chelator, showed antiproliferative activity against pancreatic cancer cells. This study aimed to elucidate the effects of combination of gemcitabine (GEM), standard chemotherapy for pancreatic cancer, and DFX in vitro and in vivo. Results GEM+DFX showed antiproliferative activity and induced apoptosis in pancreatic cancer cells in vitro. GEM+DFX suppressed xenograft tumor growth and induced apoptosis without any serious side effects compared with control, GEM, and DFX (average tumor volume: control 697 mm3 vs GEM 372 mm3, p < 0.05; GEM 372 mm3 vs GEM+DFX 234 mm3, p < 0.05). RRM1 and RRM2 protein levels were substantially reduced by DFX in BxPC-3 in vitro. Conclusion GEM+DFX has significant anticancer effects on pancreatic cancer cell through RR activity suppression. Methods BxPC-3, a human pancreatic cancer cell line, was used in all experiments. Cellular proliferation rate was measured using 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt assay. Apoptosis was evaluated by flow cytometry and by measuring caspase 3/7 activity with luminescence assay. In the tumor xenografts in nude mice models, when five weeks after engraftment, drug administration began (day 0). After treatment for 21 days, the mice were sacrificed and the tumors were excised. Apoptotic cells in xenografts were evaluated by terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick-end labeling assay. Protein levels of ribonucleotide reductase (RR) subunit 1 (RRM1) and RR subunit 2 (RRM2) in BxPC-3 cells were assessed by western blot in vitro.

Abstract
The exact mechanisms of hepatocellular carcinoma development in non-alcoholic steatohepatitis remain unclear. In this study, we used a new class of high-fat diet, which could induce hepatocellular carcinoma development without the use of general chemical carcinogens or knockout mice. We investigated the correlation between hepatocellular carcinoma and oxidative stress/anti-oxidant effects after depletion of the gut microbiota by treatment with antibiotics. Mice fed with the steatohepatitis-inducing high-fat diet (STHD-01) for 41 weeks developed hepatocellular carcinoma. Antibiotic-treatment in mice fed with STHD-01 significantly depleted the gut microbiota and significantly ameliorated liver injury/histology. The tumor numbers of hepatocellular carcinoma were dramatically decreased by the antibiotics-treatment. We analyzed the factors involved in oxidative stress and anti-oxidant effects. Oxidative stress was elevated in mice fed with STHD-01, whereas some anti-oxidant factors were significantly elevated after antibiotics treatment. These results suggest that the gut microbiota is a key factor in improving oxidative stress induced by STHD-01 feeding.

Abstract
Iron transport across the intestinal epithelium is facilitated by the divalent metal transporter 1 (DMT1) on the brush border membrane (BBM). The fluorescent metal sensor calcein, which is hydrophilic, membrane-impermeable and quenched by chelation with iron, was used to test our hypothesis that intestinal iron absorption is through the endocytic processes and is involved in a pathway where BBM-derived vesicles fuse with basolateral membrane (BLM)-derived vesicles. To monitor the flux of iron via transcytosis, Caco-2 cells were employed as a polarized cell layer in Transwell chambers. When calcein was added to the basal chamber along with apo-transferrin (apo-Tf), calcein rapidly underwent endocytosis and co-localized with apo-Tf. Calcein was quenched by adding an iron-ascorbate complex and then restored by adding 2,2'-dipyridyl into the apical chamber. These results were confirmed by live-cell imaging. When hemin from the apical surface and calcein from the basal chamber were added to the Caco-2 cells, internalization of DMT1 and quenching of calcein were not observed until 2 h later. These results indicated that absorbed hemin required processing before hemin-derived iron was available to BLM-derived vesicles. These studies suggest that iron is transported in Caco-2 cells by transcytosis with apical-derived vesicles that are fused to BLM-derived vesicles.

The preventive effect of the impaired liver function for antiemetic therapy against chemotherapy-induced nausea and vomiting in hepatocellular carcinoma patients. J Clin Biochem Nutr 2017; 61:222-227. [PMID: 29203965 PMCID: PMC5703785 DOI: 10.3164/jcbn.17-57] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Accepted: 07/11/2017] [Indexed: 11/22/2022] Open
Abstract
Transarterial chemoembolization and hepatic arterial infusion chemotherapy are recommended for the treatment in patients with intermediate stage of hepatocellular carcinoma. Impaired liver function was sometime observed in patients with hepatocellular carcinoma after transarterial chemoembolization or hepatic arterial infusion chemotherapy. However, what kinds of factors deeply influence in impaired liver function are not clear. A retrospective study was performed to evaluate the risk factors of impaired liver function in cisplatin-naïve patients treated with these therapies using cisplatin. Prior to and 2 months after these therapies, we analyzed the liver function by Child-Pugh score in these patients. For assessing the severity of chemotherapy-induced nausea and vomiting, we utilized the Common Terminology Criteria for Adverse Events ver. 4.0. In hepatocellular carcinoma patients received these therapies using cisplatin, the cancer stage and treatment without neurokinin-1 (NK1) antagonist were found to be independent risk factors of the impaired liver function. The treatment with NK1 antagonist was effective in reducing chemotherapy-induced nausea and vomiting and patients treated with NK1 antagonist kept their liver functions after cisplatin-used these therapies. The treatment with NK1 antagonist was effective in chemotherapy-induced nausea and vomiting and prevented the impaired liver function associated with cisplatin-used these therapies in hepatocellular carcinoma patients.

Effects of an oral iron chelator, deferasirox, on advanced hepatocellular carcinoma. World J Gastroenterol 2016; 22:8967-8977. [PMID: 27833388 PMCID: PMC5083802 DOI: 10.3748/wjg.v22.i40.8967] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2016] [Revised: 09/06/2016] [Accepted: 09/28/2016] [Indexed: 02/06/2023] Open
Abstract
AIM To evaluate the inhibitory effects of deferasirox (DFX) against hepatocellular carcinoma (HCC) through basic and clinical studies.
METHODS In the basic study, the effect of DFX was investigated in three hepatoma cell lines (HepG2, Hep3B, and Huh7), as well as in an N-nitrosodiethylamine-induced murine HCC model. In the clinical study, six advanced HCC patients refractory to chemotherapy were enrolled. The initial dose of DFX was 10 mg/kg per day and was increased by 10 mg/kg per day every week, until the maximum dose of 30 mg/kg per day. The duration of a single course of DFX therapy was 28 consecutive days. In the event of dose-limiting toxicity (according to the Common Terminology Criteria for Adverse Events v.4.0), DFX dose was reduced.
RESULTS Administration of DFX inhibited the proliferation of hepatoma cell lines and induced the activation of caspase-3 in a dose-dependent manner in vitro. In the murine model, DFX treatment significantly suppressed the development of liver tumors (P < 0.01), and significantly upregulated the mRNA expression levels of hepcidin (P < 0.05), transferrin receptor 1 (P < 0.05), and hypoxia inducible factor-1α (P < 0.05) in both tumor and non-tumor tissues, compared with control mice. In the clinical study, anorexia and elevated serum creatinine were observed in four and all six patients, respectively. However, reduction in DFX dose led to decrease in serum creatinine levels in all patients. After the first course of DFX, one patient discontinued the therapy. We assessed the tumor response in the remaining five patients; one patient exhibited stable disease, while four patients exhibited progressive disease. The one-year survival rate of the six patients was 17%.
CONCLUSION We demonstrated that DFX inhibited HCC in the basic study, but not in the clinical study due to dose-limiting toxicities.

Abstract
Aberrant activity of tyrosine kinases has been proved to be associated with multiple diseases including fibrotic diseases. Tyrosine kinases inhibitors (TKIs) might be a novel approach to transform the anti-fibrotic treatment. However, both beneficial and adverse effects are observed by researchers when using these TKIs in either preclinical animal models or patients with hepatic fibrosis. Since hepatotoxicity of TKIs is the leading cause for drug withdrawals thus limits its application in anti-fibrosis, not only efficacy but also safety of TKIs should be paid great concerns. It has been observed in a few studies that TKIs could induce relatively high rate of hepatic biochemical markers elevations and even result in liver failure. Fortunately, several strategies have been adopt to handle with the hepatotoxicity. Accumulating evidences suggest that hepatic stellate cells (HSC) play a pivotal role in hepatic fibrogenesis, so it might be a good option to develop selective TKIs specifically targeting HSCs. The present review will briefly summarize the anti-fibrotic mechanism of TKIs, adverse effects of TKIs as well as the novel developed selective delivery of TKIs.
