Abstract
Ferroptosis is a type of regulated cell death that plays an essential role in various brain diseases, including cranial trauma, neuronal diseases, and brain tumors. It has been reported that cancer cells rely on their robust antioxidant capacity to escape ferroptosis. Therefore, ferroptosis exploitation could be an effective strategy to prevent tumor proliferation and invasion. Glioma is a common malignant craniocerebral tumor exhibiting complicated drug resistance and survival mechanisms, resulting in a high mortality rate and short survival time. Recent studies have determined that metabolic alterations in glioma offer exploitable therapeutic targets. These metabolic alterations allow targeted therapy to achieve some initial efficacy but have failed to inhibit glioma growth, invasion, and drug resistance effectively. It has been proposed that the reason for the high malignancy and drug resistance observed with glioma is that these tumors can effectively evade ferroptosis. Ferroptosis-inducing drugs were found to exert a positive effect by targeting this particular characteristic of glioma cells. Moreover, gliomas develop enhanced drug resistance through anti-ferroptosis mechanisms. In this study, we provided an overview of the mechanisms by which glioma aggressiveness and drug resistance are mediated by the evasion of ferroptosis. This information might provide new targets for glioma therapy as well as new insights and ideas for future research.

Abstract
The challenge of eradicating cancer is that cancer cells possess diverse mechanisms to protect themselves from clinical strategies. Recently, ferroptosis has been shown to exhibit appreciable anti-tumor activity that could be harnessed for cancer therapy in the future. Ferroptosis is an iron-dependent form of regulated cell death that is characterized by the oxidization of polyunsaturated fatty acids (PUFAs) and accumulation of lipid peroxides. Ferroptosis has been closely correlated with numerous biological processes, such as amino acid metabolism, glutathione metabolism, iron metabolism, and lipid metabolism, as well as key regulators including GPX4, FSP1, NRF2, and p53. Although ferroptosis could be involved in killing various cancer cells, multiple aspects of this phenomenon remain unresolved. In this review, we summarize the biochemistry and biology of ferroptosis in diverse cancers and discuss the potential mechanisms of ferroptosis, which might pave the way for guiding cancer therapeutics.

Abstract
Subarachnoid hemorrhage (SAH) is a serious cerebrovascular disease with high mortality, and the mean age at morbidity is younger than in other types of stroke. Early brain injury (EBI) plays a key role in the poor prognoses of SAH. In EBI, multiple forms of cell death have been identified and well studied; however, the role of ferroptosis has not been elucidated. Hence, in this study, we developed an in vivo (SAH rat model) and in vitro model (SH-SY5Y oxyhemoglobin injury model) to understand the role of ferroptosis in EBI, then explored the protective mechanism of ferrostatin-1 (Fer-1). Firstly, we found that neurological scores, blood-brain barrier permeability, brain edema deteriorated after SAH in the in vivo model, cell viability was decreased after SAH in both cortex and SH-SY5Y cells. Further, iron content in cortex was increased after SAH, while transferrin receptor 1 and ferroportin (Fpn) were increased in oxyhemoglobin-treated in vitro model. Additionally, glutathione content and glutathione peroxidase 4 activity were reduced in SAH rats, and lipid peroxides were increased in the oxyhemoglobin-treated cells. Finally, administration of Fer-1 upregulated Fpn and decreased the iron content, then improved the lipid peroxidation and EBI. However, Fer-1 had no effect on the apoptosis. Our study indicated that the ferroptosis was involved in EBI of SAH, and the inhibitor Fer-1 provided neuroprotection against EBI by alleviating ferroptosis, the potential protective mechanism might be via suppressing lipid peroxidation.

miR-324-3p reverses cisplatin resistance by inducing GPX4-mediated ferroptosis in lung adenocarcinoma cell line A549. Biochem Biophys Res Commun 2021; 549:54-60.

Abstract
PURPOSE MicroRNAs act as crucial regulators of a diverse range of biological processes, including chemoresistance. Our study aimed to investigate the effect of miR-324-3p on lung adenocarcinoma cell line A549 resistant to cis-diamminedichloroplatinum II (DDP, aka cisplatin). METHODS The miR-324-3p expression levels in cisplatin-sensitive A549(A549) and cisplatin-resistant A549 (A549/DDP) cells were determined by qRT-PCR assay. Cell proliferation was determined with the commercial kit CCK-8 and colony formation assay, whereas cell death was analyzed using flow cytometry. The target gene of miR-324-3p was identified and validated with the luciferase reporter and western blot assays. The role of miR-324-3p in modulating cisplatin resistance was evaluated in vitro. RESULTS The expression of miR-324-3p was found to be significantly downregulated in the A549/DDP cells. Conversely, miR-324-3p overexpression reversed cisplatin resistance in the cells. With regard to the possible mechanism underlying this phenomenon, we identified the glutathione peroxidase 4 (GPX4) gene as the direct target of miR-324-3p, where overexpression of the gene reversed the miR-324-3p effect of sensitizing the A549/DDP cells to cisplatin. Furthermore, the GPX4 inhibitor RSL3 could mimic the effect of miR-324-3p upregulation in increasing the sensitivity of the cisplatin-resistant cells to the drug. Significantly, miR-324-3p enhanced cisplatin-induced ferroptosis in the A549/DDP cells. CONCLUSION Our findings revealed the role of the miR-324-3p-GPX4 signaling axis in A549/DDP cells and how the targeting of this axis could be a potential strategy for reversing cisplatin resistance in human non small cell lung cancer (NSCLC).

Abstract
Ferroptosis is an iron-dependent cell death, which is different from apoptosis, necrosis, autophagy, and other forms of cell death. The process of ferroptotic cell death is defined by the accumulation of lethal lipid species derived from the peroxidation of lipids, which can be prevented by iron chelators (e.g., deferiprone, deferoxamine) and small lipophilic antioxidants (e.g., ferrostatin, liproxstatin). This review summarizes current knowledge about the regulatory mechanism of ferroptosis and its association with several pathways, including iron, lipid, and cysteine metabolism. We have further discussed the contribution of ferroptosis to the pathogenesis of several diseases such as cancer, ischemia/reperfusion, and various neurodegenerative diseases (e.g., Alzheimer's disease and Parkinson's disease), and evaluated the therapeutic applications of ferroptosis inhibitors in clinics.

Abstract
Ferroptosis is a type of oxidative stress-dependent regulated necrosis characterized by excessive lipid peroxide accumulation. This novel cell death modality has been implicated in preventing cancer progression. Cancer cells tend to modulate their redox state to prevent excessive peroxidation, eventually facilitating tumor growth. System Xc- (a cystine/glutamate antiporter system) is a promising target in cancer cells for ferroptosis induction. The overexpression of system Xc-, especially its core subunit xCT, has been reported in several tumors, and these high expression levels were closely related to cancer cell proliferation, invasion, metastasis and the tumor microenvironment. xCT might serve as a novel biomarker, and its upregulation almost always indicates drug tolerance and poor survival. Therefore, system Xc- inhibition may enhance chemotherapy sensitivity and optimize patient prognosis. Here, we elaborate on the mediation of ferroptosis by suppressing system Xc- and the relevant underlying molecular mechanism in cancer cells. The spotlight on this approach to cancer treatment is creating a new horizon and pointing to future opportunities.

Abstract
Methods In this study, we used MTT assays to demonstrate that a combination of SPIO-Serum and wild-type p53 overexpression can reduce ovarian cancer cell viability in vitro. Prussian blue staining and iron assays were used to determine changes in intracellular iron concentration following SPIO-Serum treatment. TEM was used to evaluate any mitochondrial damage induced by SPIO-Serum treatment, and Western blot was used to evaluate the expression of the iron transporter and lipid peroxidation regulator proteins. JC-1 was used to measure mitochondrial membrane potential, and ROS levels were estimated by flow cytometry. Finally, xCT protein expression and mitochondrial ROS levels were confirmed using fluorescence microscopy. Results SPIO-Serum effectively induced lipid peroxidation and generated abundant toxic ROS. It also facilitated the downregulation of GPX4 and xCT, ultimately resulting in iron-dependent oxidative death. These effects could be reversed by iron chelator DFO and lipid peroxidation inhibitor Fer-1. SPIO-Serum treatment disrupted intracellular iron homeostasis by regulating iron uptake and the cells presented with missing mitochondrial cristae and ruptured outer mitochondrial membranes. Moreover, we were able to show that p53 contributed to SPIO-Serum-induced ferroptosis in ovarian cancer cells. Conclusion SPIO-Serum induced ferroptosis and overexpressed p53 contributed to ferroptosis in ovarian cancer cells. Our data provide a theoretical basis for ferroptosis as a novel cell death phenotype induced by nanomaterials.

Abstract
Ferroptosis is a dedicated mode of cell death involving iron, reactive oxygen species and lipid peroxidation. Involved in processes such as glutathione metabolism, lysosomal iron retention or interference with lipid metabolism, leading either to activation or inhibition of ferroptosis. Given the implications of ferroptosis in diseases such as cancer, aging, Alzheimer and infectious diseases, new molecular mechanisms underlying ferroptosis and small molecules regulators that target those mechanisms have prompted a great deal of interest. Here, we discuss the current scenario of small molecules modulating ferroptosis and critically assess what is known about their mechanisms of action.

Abstract
Regulated cell death (RCD) is a universal process in living organisms that is essential for tissue homeostasis or to the restoration of biological equilibrium following stress. Ferroptosis is a specific nonapoptotic cell death that is dependent on iron and is very different from other forms of RCD. Ferroptosis can affect the development of liver diseases such as drug-induced liver injury (DILI), liver fibrosis, and hepatocellular carcinoma (HCC) by regulating the level of intracellular iron, the production of intracellular reactive oxygen species, and lipid peroxides. In this review, we summarize the current knowledge of ferroptosis, in terms of discovery, history, characteristics, mechanism, and the factors regulating liver diseases. We discuss how these factors and signaling pathways change in the context of liver disease. Furthermore, we focus on delineating the roles of effective therapeutic drugs or compounds in liver disease. In summary, we discuss the role of ferroptosis in liver disease, providing a strategy and new ideas for preventing liver disease, finding new therapeutic targets, and reducing liver damage.

Abstract
Background Esophageal squamous cell carcinoma (ESCC) is a common malignant tumor of the digestive system. Studies have shown that pseudolaric acid B (PAB) has several pharmacological effects like anti-microtubule, anti-angiogenesis, and antitumor functions, while the effect and mechanism of PAB on esophageal cancer are still unclear. This study was designed to investigate the effects of PAB on ESCC. Methods To study the effects of PAB on the biological function through a series of in vitro and in vivo experiments. Results The results revealed that PAB inhibited the proliferation, invasion, and migration, but promoted the apoptosis of ESCC. Moreover, PAB restrained the growth of cancer cells in vivo and inhibited the angiogenesis of HUVEC in mice with ESCC. CD147 expression was increased in the esophageal squamous cell lines, and interference with CD147 hindered the proliferation, invasion, and migration of ESCC cells, and inhibited the growth and angiogenesis of the esophageal squamous cell line. PAB reduced the expression of CD147 in vivo and in vitro. The expression of MMP2, 3, and 9 was increased after overexpression of CD147, which provided the opportunity to reverse the role of PAB in inhibiting proliferation, invasion, migration, and angiogenesis of ESCC. Discussion The results revealed that PAB inhibited the proliferation, invasion, migration, and angiogenesis of ESCC in vitro and in vivo by CD147. PAB is a promising monomer for therapy of ESCC, providing references for future research on ESCC treatment.

Abstract
Rapid increase in aging populations is an urgent problem because older adults are more likely to suffer from disabilities and age-related diseases (ARDs), burdening healthcare systems and society in general. ARDs are characterized by the progressive deterioration of tissues and organs over time, eventually leading to tissue and organ failure. To date, there are no effective interventions to prevent the progression of ARDs. Hence, there is an urgent need for new treatment strategies. Ferroptosis, an iron-dependent cell death, is linked to normal development and homeostasis. Accumulating evidence, however, has highlighted crucial roles for ferroptosis in ARDs, including neurodegenerative and cardiovascular diseases. In this review, we a) summarize initiation, regulatory mechanisms, and molecular signaling pathways involved in ferroptosis, b) discuss the direct and indirect involvement of the activation and/or inhibition of ferroptosis in the pathogenesis of some important diseases, and c) highlight therapeutic targets relevant for ARDs.

Ibuprofen induces ferroptosis of glioblastoma cells via downregulation of nuclear factor erythroid 2-related factor 2 signaling pathway. Anticancer Drugs 2020; 31:27-34.

Abstract
Ferroptosis is a newly discovered type of cell death decided by iron-dependent lipid peroxidation, but its role in glioblastoma cell death remains unclear. Ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), has been associated with antitumorigenic effects in many cancers. In this study, we first found that ibuprofen inhibited the viabilities of glioblastoma cells in vitro and in vivo, accompanied by abnormal increase in intracellular lipid peroxidation. Further study showed that the cell growth inhibition caused by ibuprofen could be rescued by the ferroptosis inhibitors deferoxamine (DFO), ferrostatin-1 and Liproxstatin-1. Nuclear factor erythroid 2-related factor 2 (Nrf2), glutathione peroxidase 4 (GPX4) and solute carrier family 7 member 11 (SLC7A11) are key regulators of ferroptosis. Our data showed that Nrf2, GPX4 and SLC7A11 were downregulated in glioblastoma cells under ibuprofen treatment. Interestingly, we found that decreased mRNA expression of GPX4 and SLC7A11 was accompanied with reduced Nrf2, which is a redox sensitive transcription factor that controls the expression of intracellular redox-balancing proteins such as GPX4 and SLC7A11. All the data suggested that Nrf2 could regulate the expression of GPX4 and SLC7A11 in glioma cells. Taken together, our findings reveal that ibuprofen could induce ferroptosis of glioblastoma cells via downregulation of Nrf2 signaling pathway and is a potential drug for glioma treatment.

Abstract
Aluminum (Al), a neurotoxic element, can induce Alzheimer's disease (AD) via triggering neuronal death. Ferroptosis is a new type of programmed cell death related to neurological diseases. Unfortunately, its role in aluminum-induced neuronal death remains completely unclear. This study aimed to investigate whether ferroptosis is involved in neuronal death in response to aluminum exposure as well as its underlying mechanism. In this study, rat adrenal pheochromocytoma (PC12) cells were treated with 200 μM aluminum maltolate (Al(mal)3) for 24 h, and related biochemical indicators were assessed to determine whether ferroptosis was induced by aluminum in neurons. Then, the potential mechanism was explored by detecting of these genes and proteins associated with ferroptosis after adding ferroptosis-specific agonist Erastin (5 μM) and antagonist Ferrostatin-1 (Fer-1) (5 μM). The experimental results demonstrated that aluminum exposure significantly increased the death of PC12 cells and caused specific mitochondrial pathological changes of ferroptosis in PC12 cells. Further research confirmed that ferroptosis was triggered by aluminum in PC12 cells by means of activating the oxidative damage signaling pathway, which was displayed as inhibition of the cysteine/glutamate antiporter system (system Xc-), causing the depletion of cellular glutathione (GSH) and inactivation of glutathione peroxidase (GSH-PX) eventually lead to accumulation of reactive oxygen species (ROS). Taken together, ferroptosis was a means of neuronal death induced by aluminum and oxidative damage may be its underlying mechanism, which also provided some new clues to potential target for the intervention and therapy of AD.

Abstract
Erastin is a small molecular compound that induces ferroptosis by binding to voltage-dependent anion-selective channel protein (VDAC)2, VDAC3 and solute carrier family 7 member 5 inhibiting the cystine/glutamate antiporter. However, to the best of our knowledge, the mechanism of erastin-induced breast cancer cell death remains unclear. In present study aimed to explore the underlying mechanisms of the antitumor effects of erastin on breast cancer cells. Cellular viability was assessed using an MTT assay, a lactate dehydrogenase cytotoxicity assay kit was used to determine the cell death rate, the intracellular Fe2+ levels were determined using an iron colorimetric assay kit and western blotting was used to estimate the changes of autophagy-associated proteins levels. The present study demonstrated that erastin inhibited the viability of breast cancer cells and induced breast cancer cell death in a dose-dependent manner. Additionally, autophagy was activated by erastin, as demonstrated by upregulated expression levels of autophagy-associated proteins in breast cancer cells. Bafilomycin A1, 3-methyladenine and knockdown of autophagy related (ATG)5 with small interfering RNA prevented erastin-induced breast cancer cell death and inhibited the erastin-induced changes in the expression levels of the autophagy-associated proteins beclin1, ATG5, ATG12, microtubule-associated proteins 1A/1B light chain 3B (LC3B) and P62. Furthermore, erastin-induced breast cancer cell death was inhibited by an iron chelator, deferoxamine, which inhibited the increases of erastin-induced iron levels and inhibited the erastin-induced changes in the expression levels of the autophagy-related proteins beclin1, ATG5, ATG12, LC3B and P62. In summary, erastin triggered autophagic death in breast cancer cells by increasing intracellular iron levels.

Abstract
Ferroptosis is a form of necrosis caused by iron-induced accumulation of lipid hydroperoxide, involving several molecular events, and has been implicated in Parkinson's disease. Gastrodin is a component of Gastrodia elata Blume with strong antioxidant activity. We examined whether gastrodin can prevent H2O2-induced cytotoxicity in rat glioma cell line C6. For this purpose, C6 cells were pretreated with gastrodin (1, 5, 25 µM) and then exposed to 100 µM H2O2. Results showed that pretreatment of C6 cells with gastrodin decreased H2O2-induced lactate dehydrogenase (LDH) release and cell death. Moreover, gastrodin decreased intracellular malondialdehyde (MDA) level, whereas increased glutathione peroxidase (GPX) activity and glutathione (GSH) level after H2O2 treatment. In addition, treatment of deferoxamine (DFO), ferrostatin-1, and liproxstatin-1 abolished ferroptosis induced by H2O2 or erastin pretreatment. Treatment with gastrodin attenuated H2O2-induced ferroptosis and decreased lipid reactive oxygen species (ROS) (C11-BODIPY) production in C6 cells. Moreover, gastrodin increased the protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2), GPX4, ferroportin-1 (FPN1), and heme oxygenase-1 (HO-1) in C6 cells treated with H2O2. RSL3, a GPX4 inhibitor, inhibited GPX4 protein level in cells co-treated with gastrodin and 100 µM H2O2. These findings indicate that gastrodin can inhibit H2O2-induced ferroptosis through its antioxidative effect in C6 cells.

Abstract
Ferroptosis is a newly identified and novel form of cell death, which is characterized by an iron- and reactive oxygen species (ROS)-dependent manner. Potential utility of ferroptotic cell death has been recently proposed for cancer treatment. Meanwhile, ROS generation and apoptosis are inherently consequent to cell apoptosis and dysfunction during islet cell preparation and transplantation. Whether ferroptosis induction is a regulator for cell viability and function in human pancreatic islet-cell clusters (ICCs) derived from pancreatic progenitor cells (PPCs) remains elusive. We thus sought to induce ferroptosis in our established cell culture system of human PPCs/ICCs, examine the effects of ferroptosis on ICCs, and explore the potential regulatory pathways involved. Our results showed that ICCs were prone to the use of ferroptosis-inducing and inhibiting agents under our culture conditions. Erastin, a ferroptosis inducer, was found to trigger ferroptosis in ICCs, without the apparent detection of other types of cell death involved, such as apoptosis and autophagy. In corroboration, the use of ferroptosis inhibitor, ferrostatin-1 (Fer-1), was found to enhance the cell viability of ICCs and prevent them from ferroptosis as well as improve its function. Mechanistically, the erastin-induced ferroptosis in ICCs was probably mediated via activation of JNK/P38/MAPK pathways and upregulation of NOX4 expression. Together, our findings may provide a scientific basis of ferroptosis inhibition as a potential for the amelioration of ICC survival and functionality during islet transplantation in diabetic patients.

Abstract
Colorectal cancer (CRC) is one of the most pressing health issues in today's society. As such, it is imperative that the scientific community devise effective methods to inhibit the proliferation and metastasis of CRC cells. Ferroptosis is a recently discovered regulatory cell death mode mainly manifested by dysregulation of cellular iron metabolism and mitochondrial lipid peroxidation. ACADSB is a member of the acyl-CoA dehydrogenase. This study finds that ACADSB is lowly expressed in CRC tissues. Its expression is negatively correlated with N- and M-stage CRC but positively correlated with the overall survival rate of CRC patients. In addition, it finds that ACADSB is found in the mitochondria of cells. Overexpression of ACADSB inhibits CRC cell migration, invasion, and proliferation, while ACADSB knockdown has the opposite effect. More importantly, the study finds that ACADSB negatively regulates expression of glutathione reductase and glutathione peroxidase 4, the two main enzymes responsible for clearing glutathione (GSH) in CRC cells. ACADSB overexpression enhances the concentration of malondialdehyde, Fe+ , superoxide dismutase, and lipid peroxidation in CRC cells, but reduces the concentration of GSH. This is significant, as all of these are important indicators of ferroptosis. Evaluating the data as a whole, this paper speculates that ACADSB affects CRC cell migration, invasion, and proliferation by regulating CRC cell ferroptosis.

Abstract
Recent advances in the biomedical importance of H2S have help us understand various cellular functions and pathophysiological processes from a new aspect. Specially, H2S has been demonstrated to play multiple roles in regulating cell behaviors, including cell survival, cell differentiation, cell senescence, cell hypertrophy, cell atrophy, cell metaplasia, and cell death, etc. H2S contributes to cell behavior changes via various mechanisms, such as histone modification, DNA methylation, non-coding RNA changes, DNA damage repair, transcription factor activity, and post-translational modification of proteins by S-sulfhydration, etc. In this review, we summarized the recent research progress on H2S signaling in control of cell behaviors and discussed the ways of H2S regulation of gene expressions. Given the key roles of H2S in both health and diseases, a better understanding of the regulation of H2S on cell behavior change and the underlying molecular mechanisms will help us to develop novel and more effective strategies for clinical therapy.

Abstract
It has been demonstrated from previous studies about the killing effect of dihydroartemisinin (DHA) on glioblastoma, which involves multiple aspects: cytotoxicity, cell cycle arrest and invasion inhibition. DHA has the advantages of low cytotoxicity to normal cells, selective killing effect and low drug resistance, making it one of the popular anti-tumor research directions. Ferroptosis is a newly discovered form of cell death characterized by iron dependence and lipid reactive oxygen species (ROS) accumulation. In the present study, we found differences in the expression of transferrin receptors in normal human astrocytes (NHA) and glioblastoma cells (U87 and A172), which may be one of the mechanisms of DHA selective killing effect. Through the determination of ferroptosis-related protein expression, we found that the significant decrease of GPX4, accompanied by the constant expression of xCT and ACSL4, suggesting GPX4 was a pivotal target for DHA-activated ferroptosis in glioblastoma. Total and lipid ROS levels were increased and all these results could be reversed by the ferroptosis inhibitor, ferrostatin-1. These findings demonstrated ferroptosis would be a critical component of cell death caused by DHA and GPX4 was the main target. All these results provide a novel treatment direction to glioblastoma. The association between ferroptosis and polyamines is also discussed, which will provide new research directions for ferroptosis caused by DHA in glioblastoma.

Abstract
Ferroptosis is a new iron and reactive oxygen species dependent programmed cell death process which is different from apoptosis, necrosis, and autophagy. It is closely related to a number of disease progression including cancers, neurodegenerative disease, cerebral hemorrhage, liver disease, and renal failure. The development of different ferroptotic inducers has been proved as an efficient therapeutic strategy for a variety of chemoradiotherapy-resistant cancer cells and cancer stem cells. In addition, the development of ferroptotic inhibitors is also becoming an emerging research hotspot for the treatment of many non-cancerous diseases. Furthermore, the combination of nanotechnology with ferroptotic therapies has exhibited additional advantages such as enhanced targeting and/or stimuli-responsive ability to tumor microenvironment, ameliorated drug solubility, ease of preparation and the integration of multifunctional theranostic platforms to develop synergetic combined therapies of great clinical importance. This paper reviews the latest advances of using tailored ferroptotic nanoparticles and ferroptotic molecular probes to be relevant for the accurate diagnosis and treatment of different diseases. Finally, the opportunities and challenges of this burgeoning field were spotlighted to promote the rational design of nano-ferroptotic drugs or theranostic probes in the near future.

Pseudolaric acid B induces mitotic arrest and apoptosis in both imatinib-sensitive and -resistant chronic myeloid leukaemia cells. Eur J Pharmacol 2020; 876:173064. [PMID: 32179085 DOI: 10.1016/j.ejphar.2020.173064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2020] [Revised: 02/29/2020] [Accepted: 03/10/2020] [Indexed: 10/24/2022]
Abstract
The selective BCR-ABL tyrosine kinase inhibitor imatinib is one of the first-line therapies in the management of chronic myeloid leukaemia (CML). However, acquired resistance to this inhibitor, which is especially conferred by the T315I point mutation in BCR-ABL, impedes the efficacy of imatinib therapy. Therefore, the discovery and development of novel agents to overcome imatinib resistance is urgently needed. Pseudolaric acid B (PAB), a small molecule isolated from the traditional Chinese medicine Cortex pseudolaricis, has been reported to be a potential candidate for immune disorders and cancer treatment. However, its effects on CML and the involved molecular mechanism have not been reported. In the current study, by performing both in vitro and in vivo experiments in CML cells, we showed that PAB blocked the cell cycle at G2/M phase and subsequently activated the caspase pathway, cleaved the BCR-ABL protein and inhibited the BCR-ABL downstream pathways, ultimately leading to cell proliferation inhibition, cytotoxicity and apoptosis. These events were observed in both imatinib-sensitive and imatinib-insensitive CML cell lines. Moreover, PAB decreased the viability of primary blood mononuclear cells from CML patients and induced apoptosis in these cells. Our findings suggest that PAB could be used as a novel agent to sensitize imatinib-resistant CML.

Abstract
Papillary thyroid carcinoma (PTC) is the most common subtype of differentiated thyroid cancers in Asian coastal cities, where the patients have increased risk of potentially high or excessive iodine intake. Given the high metastasis and recurrence of patients with BRAFV600E mutation, the mortality rate of thyroid cancer has recently shown an upward trend. A variety of therapies, including surgery, radiotherapy, and chemotherapy, have been used to treat thyroid cancer, but these therapies still have limitations, including postoperative complications, drug resistance, poor efficacy, or serious side effects. Recent studies have shown the potential of active ingredients derived from herbal medicine in inhibiting PTC via various cell signaling pathways. Some plant-derived compounds, such as apigenin, genistein, and curcumin, are also known to prevent and treat PTC. This article summarizes the recent advances in the structure-functional impact of anti-PTC active ingredients and their effects on PTC cells and tumor microenvironments with an emphasis on their challenges from basic research to clinical practice.

Abstract
The most common malignant brain tumors are those of astrocytic origin, gliomas, with the most aggressive glioblastoma (WHO grade IV) among them. Despite efforts, medicine has not made progress in terms of the prognosis and life expectancy of glioma patients. Behind the malignant phenotype of gliomas lies multiple genetic mutations leading to reprogramming of their metabolism, which gives those highly proliferating cells an advantage over healthy ones. The so-called glutamine addiction is a metabolic adaptation that supplements oxidative glycolysis in order to secure neoplastic cells with nutrients and energy in unfavorable conditions of hypoxia. The present review aims at presenting the research and clinical attempts targeting the different metabolic pathways involved in glutamine metabolism in gliomas. A brief description of the biochemistry of glutamine transport, synthesis, and glutaminolysis, etc. will forego a detailed comparison of the therapeutic strategies undertaken to inhibit glutamine utilization by gliomas.

Abstract
The iron chelator deferoxamine has been shown to inhibit ferroptosis in spinal cord injury. However, it is unclear whether deferoxamine directly protects neurons from ferroptotic cell death. By comparing the survival rate and morphology of primary neurons and SH-SY5Y cells exposed to erastin, it was found that these cell types respond differentially to the duration and concentration of erastin treatment. Therefore, we studied the mechanisms of ferroptosis using primary cortical neurons from E16 mouse embryos. After treatment with 50 μM erastin for 48 hours, reactive oxygen species levels increased, and the expression of the cystine/glutamate antiporter system light chain and glutathione peroxidase 4 decreased. Pretreatment with deferoxamine for 12 hours inhibited these changes, reduced cell death, and ameliorated cellular morphology. Pretreatment with the apoptosis inhibitor Z-DEVD-FMK or the necroptosis inhibitor necrostain-1 for 12 hours did not protect against erastin-induced ferroptosis. Only deferoxamine protected the primary cortical neurons from ferroptosis induced by erastin, confirming the specificity of the in vitro ferroptosis model. This study was approved by the Animal Ethics Committee at the Institute of Radiation Medicine of the Chinese Academy of Medical Sciences, China (approval No. DWLL-20180913) on September 13, 2018.

Abstract
Pancreatic cancer is characterized by aggressive and highly metastatic phenotypes. This disease exhibits a poor patient prognosis and is considered a challenge due to the limited treatment options encountered in clinical practice. Previous studies have shown that ruscogenin, a saponin found in the root of Ophiopogon japonicus, exerts a wide range of biological functions including anticancer activity. In the present study, the effects of ruscogenin were investigated on pancreatic cancer cells and the potential molecular mechanism of this compound was explored. Cell viability was assessed using the 3-(4,5-di-2-yl)-2,5-ditetrazolium bromide (MTT) assay. Cell death was measured by trypan blue staining and by flow cytometry. The number of iron oxide nanoparticles was measured using Prussian blue staining. Reactive oxygen species (ROS) production was assessed using flow cytometry with dihydroethidium staining. Protein expression of the associated genes was assayed by western blotting. Furthermore, in vivo experiments were conducted to confirm the antitumor effects and assay the potential toxicity of ruscogenin in a nude mouse xenograft model. The results indicated that ruscogenin significantly repressed cell viability and induced cell death of pancreatic cancer cells in vitro in a dose- and time-dependent manner. Furthermore, ruscogenin increased the concentration of intracellular ferrous irons and the production of ROS. This effect was inhibited by deferoxamine (DFO). Ruscogenin induced ferroptosis by regulating the levels of transferrin and ferroportin. These two proteins were involved in ruscogenin-induced pancreatic cancer cell death. Finally, in vivo experiments demonstrated the antitumor effect of ruscogenin on pancreatic cancer xenografts in the absence of apparent toxicity. Taken collectively, the data demonstrated that ruscogenin exhibited anticancer effects in pancreatic cancer cells by inducing ferroptosis. The findings suggested that this compound may be further developed as a promising anticancer candidate for the treatment of pancreatic cancer.

Abstract
Acyl-CoA synthetase long-chain family member 4 (ACSL4) is a member of the long chain family of acyl-CoA synthetase proteins, which have recently been shown to serve an important role in ferroptosis. Previous studies have suggested that ferroptosis is involved in the occurrence of glioma; however, the role of ACSL4 in glioma remains unknown. In the present study, a reduction of ferroptosis in human glioma tissues and glioma cells was observed. Subsequently, it was demonstrated that the expression of ACSL4 was also downregulated in human glioma tissues and cells. A ferroptosis inhibitor and inducer were used to investigate the effects of ferroptosis on viability. The results showed that promoting ferroptosis inhibited the proliferation of glioma cells, and that the use of inducers had the reverse effect. Therefore, it was hypothesized that the reduction in ACSL4 expression may have been involved in ferroptosis and proliferation in glioma. Overexpression of ACSL4 decreased expression of glutathione peroxidase 4 and increased the levels of ferroptotic markers, including 5-hydroxyeicosatetraenoic (HETE), 12-HETE and 15-HETE. Additionally, ACSL4 overexpression resulted in an increase in lactate dehydrogenase release and a reduction in cell viability. The opposite results were observed when ACSL4 was silenced. These findings suggest that ACSL4 regulates ferroptosis and proliferation of glioma cells. To further investigate the mechanism underlying ACSL4-mediated regulation of proliferation in glioma cells, cells were treated with small interfering (si)-ACSL4 and sorafenib, a ferroptosis inducer. sorafenib attenuated the ability of siRNA-mediated silencing of ACSL4, thus improving cell viability. These results demonstrate that ACSL4 protects glioma cells and exerts anti-proliferative effects by activating a ferroptosis pathway and highlight the pivotal role of ferroptosis regulation by ACSL4 in its protective effects on glioma. Therefore, ACSL4 may serve as a novel therapeutic target for the treatment of glioma.

Abstract
Loss of myocytes caused by cell death plays a key role during heart failure (HF). Activated autophagy and increased ferroptosis have been observed in HF and proved to promote its progression. However, the underlying mechanisms remain unclear. Here, results from integrated bioinformatical analysis showed TLR4 and NADPH oxidase 4 (NOX4) were included in up-regulated differentially expressed genes (DEGs), and had an interaction between each other inferred by the DEGs-associated protein-protein interaction (PPI) network. To explore the role of TLR4-NOX4 in autophagy and ferroptosis, knock-down of TLR4 and NOX4 through lentiviral delivery of siRNA to the myocardium were applied respectively in HF rats induced by aortic banding, and the indicators of autophagy and ferroptosis were detected. Results revealed that either TLR4 or NOX4 knock-down significantly improved left ventricular remodeling and reduced myocytes death. Simultaneously, activated autophagy and ferroptosis in rats with HF were remarkably retarded by either TLR4 and NOX4 knock-down, suggesting TLR4-NOX4 as a potential therapeutic target for HF through inhibiting autophagy- and ferroptosis-mediated cell death.

Abstract
Glutathione is the principal intracellular antioxidant buffer against oxidative stress and mainly exists in the forms of reduced glutathione (GSH) and oxidized glutathione (GSSG). The processes of glutathione synthesis, transport, utilization, and metabolism are tightly controlled to maintain intracellular glutathione homeostasis and redox balance. As for cancer cells, they exhibit a greater ROS level than normal cells in order to meet the enhanced metabolism and vicious proliferation; meanwhile, they also have to develop an increased antioxidant defense system to cope with the higher oxidant state. Growing numbers of studies have implicated that altering the glutathione antioxidant system is associated with multiple forms of programmed cell death in cancer cells. In this review, we firstly focus on glutathione homeostasis from the perspectives of glutathione synthesis, distribution, transportation, and metabolism. Then, we discuss the function of glutathione in the antioxidant process. Afterwards, we also summarize the recent advance in the understanding of the mechanism by which glutathione plays a key role in multiple forms of programmed cell death, including apoptosis, necroptosis, ferroptosis, and autophagy. Finally, we highlight the glutathione-targeting therapeutic approaches toward cancers. A comprehensive review on the glutathione homeostasis and the role of glutathione depletion in programmed cell death provide insight into the redox-based research concerning cancer therapeutics.

Abstract
BACKGROUND Non-small cell lung carcinoma (NSCLC) is a major worldwide health threat due to its low cure rate and high lethality. Emerging evidence suggests that epidermal growth factor receptor (EGFR) plays vital roles in cancer initiation and progression, and is considered an important cancer-driving protein. However, how EGFR expression is regulated during NSCLC development remains to be fully elucidated. METHODS In NSCLC clinical samples, EGFR protein levels were measured by western blotting and qRT-PCR, respectively. Combining microRNA (miRNA) target prediction software and the pulldown assay, we predicted microRNAs (miRNAs) that targeted EGFR. Next, three NSCLC cell lines, A549 (p53 WT), H322 (p53 mutant), and H1299 (p53 null), were used to demonstrate the direct targeting of EGFR by miR-193a. In addition, we investigated the biological effects of EGFR inhibition by miR-193a in vitro using Cell Counting Kit-8, 5-Ethynyl-2'-deoxyuridine (EdU), transwell, and apoptosis assays. Then, using ChIP and luciferase assays, we demonstrated that miR-193a was directly activated by p53 at the transcriptional level and that p53-induced-miR-193a and EGFR form a double-negative feedback loop. RESULTS We found that EGFR mRNA and protein were upregulated in NSCLC. We predicted that EGFR was a target of miR-193a and validated that miR-193a bound directly to the 3'-UTR of the EGFR mRNA. Moreover, miR-193a inhibited NSCLC proliferation and invasion, and promotes NSCLC apoptosis by directly downregulating EGFR. Then, we demonstrated that p53 directly activated miR-193a transcription, whereas EGFR functioned as a transcriptional repressor to negatively control miR-193a expression, forming a feedback loop. The loop promoted NSCLC cell proliferation and migration and accelerated tumor growth in xenograft mice. CONCLUSIONS This study highlights a double-negative feedback loop in NSCLC. The feedback loop is crucial because overexpressing EGFR strongly accelerated tumor growth, while miR-193a restoration blocked tumor growth in vivo. Our findings are in line with the emerging opinion that miRNAs and protein regulators form regulatory networks in critical biological processes and that their dysregulation can lead to cellular dysfunction. In conclusion, this study provides important insights into the molecular mechanisms of NSCLC progression and may help inform the development of new therapeutics for managing NSCLC.

Sui S, Zhang J, Xu S, Wang Q, Wang P, Pang D. Ferritinophagy is required for the induction of ferroptosis by the bromodomain protein BRD4 inhibitor (+)-JQ1 in cancer cells. Cell Death Dis 2019; 10:331. [PMID: 30988278 PMCID: PMC6465411 DOI: 10.1038/s41419-019-1564-7] [Citation(s) in RCA: 132] [Impact Index Per Article: 26.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2018] [Revised: 03/07/2019] [Accepted: 04/02/2019] [Indexed: 12/16/2022]
Abstract
(+)-JQ1 is an inhibitor of the tumor-driver bromodomain protein BRD4 and produces satisfactory effects because it efficiently increases apoptosis. Ferroptosis is an oxidative cell death program differing from apoptosis. Ferroptosis is characterized by high levels of iron and reactive oxygen species and has been confirmed to suppress tumor growth. In this study, BRD4 expression in cancer and its influence on the prognosis of cancer patients were analyzed using data from public databases. In addition, the effect of the BRD4 inhibitor (+)-JQ1 on ferroptosis was investigated via a series of in vitro assays. A nude mouse model was used to evaluate the function of (+)-JQ1 in ferroptosis in vivo. The potential mechanisms by which (+)-JQ1 regulates ferroptosis were explored. The results showed that BRD4 expression levels were higher in cancer tissues than in normal tissues and were related to poor prognosis in cancer patients. Furthermore, ferroptosis was induced under (+)-JQ1 treatment and BRD4 knockdown, indicating that (+)-JQ1 induces ferroptosis via BRD4 inhibition. Moreover, the anticancer effect of (+)-JQ1 was enhanced by ferroptosis inducers. Further studies confirmed that (+)-JQ1 induced ferroptosis via ferritinophagy, which featured autophagy enhancement by (+)-JQ1 and increased iron levels. Subsequently, the reactive oxygen species levels were increased by iron via the Fenton reaction, leading to ferroptosis. In addition, expression of the ferroptosis-associated genes GPX4, SLC7A11, and SLC3A2 was downregulated under (+)-JQ1 treatment and BRD4 knockdown, indicating that (+)-JQ1 may regulate ferroptosis by controlling the expression of ferroptosis-associated genes regulated by BRD4. Finally, (+)-JQ1 regulated ferritinophagy and the expression of ferroptosis-associated genes via epigenetic inhibition of BRD4 by suppressing the expression of the histone methyltransferase G9a or enhancing the expression of the histone deacetylase SIRT1. In summary, the BRD4 inhibitor (+)-JQ1 induces ferroptosis via ferritinophagy or the regulation of ferroptosis-associated genes through epigenetic repression of BRD4.
