Park WH. Propyl gallate induces human pulmonary fibroblast cell death through the regulation of Bax and caspase-3. Ann Med 2024; 56:2319853. [PMID: 38373208 PMCID: PMC10878342 DOI: 10.1080/07853890.2024.2319853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Accepted: 02/11/2024] [Indexed: 02/21/2024] Open
Abstract
Propyl gallate (PG) has been found to exert an inhibitory effect on the growth of different cell types, including lung cancer cells. However, little is known about the cytotoxicological effects of PG specifically on normal primary lung cells. The current study examined the cellular effects and cell death resulting from PG treatment in human pulmonary fibroblast (HPF) cells. DNA flow cytometry results demonstrated that PG (100-1,600 μM) had a significant impact on the cell cycle, leading to G1 phase arrest. Notably, 1,600 μM PG slightly increased the number of sub-G1 cells. Additionally, PG (400-1,600 μM) resulted in the initiation of cell death, a process that coincided with a loss of mitochondrial membrane potential (MMP; ΔΨm). This loss of MMP (ΔΨm) was evaluated using a FACS cytometer. In PG-treated HPF cells, inhibitors targeting pan-caspase, caspase-3, caspase-8, and caspase-9 showed no significant impact on the quantity of annexin V-positive and MMP (ΔΨm) loss cells. The administration of siRNA targeting Bax or caspase-3 demonstrated a significant attenuation of PG-induced cell death in HPF cells. However, the use of siRNAs targeting p53, Bcl-2, or caspase-8 did not exhibit any notable effect on cell death. Furthermore, none of the tested MAPK inhibitors, including MEK, c-Jun N-terminal kinase (JNK), and p38, showed any impact on PG-induced cell death or the loss of MMP (ΔΨm) in HPF cells. In conclusion, PG induces G1 phase arrest of the cell cycle and cell death in HPF cells through apoptosis and/or necrosis. The observed HPF cell death is mediated by the modulation of Bax and caspase-3. These findings offer insights into the cytotoxic and molecular effects of PG on normal HPF cells.

Immunoglobulin Superfamily Containing Leucine-Rich Repeat (ISLR) Serves as a Redox Sensor That Modulates Antioxidant Capacity by Suppressing Pyruvate Kinase Isozyme M2 Activity. Cells 2024; 13:838. [PMID: 38786060 PMCID: PMC11119796 DOI: 10.3390/cells13100838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2024] [Revised: 05/05/2024] [Accepted: 05/11/2024] [Indexed: 05/25/2024] Open
Abstract
Cells defend against oxidative stress by enhancing antioxidant capacity, including stress-activated metabolic alterations, but the underlying intracellular signaling mechanisms remain unclear. This paper reports that immunoglobulin superfamily containing leucine-rich repeat (ISLR) functions as a redox sensor that responds to reactive oxygen species (ROS) stimulation and modulates the antioxidant capacity by suppressing pyruvate kinase isozyme M2 (PKM2) activity. Following oxidative stress, ISLR perceives ROS stimulation through its cysteine residue 19, and rapidly degrades in the autophagy-lysosome pathway. The downregulated ISLR enhances the antioxidant capacity by promoting the tetramerization of PKM2, and then enhancing the pyruvate kinase activity, PKM2-mediated glycolysis is crucial to the ISLR-mediated antioxidant capacity. In addition, our results demonstrated that, in triple-negative breast cancer, cisplatin treatment reduced the level of ISLR, and PKM2 inhibition sensitizes tumors to cisplatin by enhancing ROS production; and argued that PKM2 inhibition can synergize with cisplatin to limit tumor growth. Our results demonstrate a molecular mechanism by which cells respond to oxidative stress and modulate the redox balance.

Abstract
Shikonin is a naphthoquinone pigment present in the hairy roots of the plant species from the Boraginaceae family. The compound has been well investigated for its highly efficient medicinal, antioxidant, and antimicrobial properties. Various extraction methodologies have been employed to maximise yield while minimising waste production of shikonin and its derivatives. Despite substantial research on shikonin and Boraginaceae plants, a research gap persists in the food industry and extraction technologies. This review addresses crucial aspects of shikonin deserving of further exploration. It begins by elucidating the attributes of the Boraginaceae plants and their medicinal traits in folklore. It proceeds to focus on the roots of the plant and its medicinal properties, followed by extraction procedures explored in the last fifteen years, emphasising the novel technologies that have been chosen to improve the yield extract while minimising extraction times. Furthermore, this review briefly outlines studies employing cell culture techniques to enhance in vitro shikonin production. Lastly, attention is directed towards research in the food industry, particularly on shikonin-loaded biodegradable films and the antioxidant activity of shikonin. This review concludes by summarising the future potential in food science and prominent research gaps in this field.

Network pharmacology and in vitro experiments reveal sophoridine-induced apoptosis and G 1 phase arrest via ROS-dependent PI3K/Akt/FoxO3a pathway activation in human bladder cancer cells. Chem Biol Drug Des 2024; 103:e14476.

Abstract
Bladder cancer (BLCA), a common primary malignancy, exhibits resistance to conventional chemotherapeutic agents. Sophoridine (SR) is a quinoline alkaloid derived from the traditional Chinese herb Sophora alopecuroides L., which belongs to the legume family Sophoraceae. SR is reported to exert growth-inhibitory effects against several cancers. However, the mechanisms underlying the growth-inhibitory effects of SR on BLCA have not been elucidated. This study performed molecular and cellular experiments to verify the growth-inhibitory effects of SR on BLCA and the underlying mechanisms. SR inhibited cell proliferation and promoted apoptosis and G1-phase arrest through the PI3K/AKT/FoxO3a signaling pathway. More interestingly, the effects of SR can be attributed to the accumulation of reactive oxygen species (ROS) in vivo. ROS may be the upstream factor of this pathway. Additionally, SR inhibited the migration and invasion of BLCA cells in a concentration-dependent or time-dependent manner. This is the first study to demonstrate the ROS-dependent PI3K/AKT/FoxO3a pathway-mediated anticancer effect of SR and the anticancer mechanism of SR in BLCA. The correlation between SR-induced ROS-dependent cell proliferation inhibition, apoptosis, cell cycle arrest, and PI3K/AKT/FoxO3a suggests that SR is a promising novel therapeutic for BLCA.

Abstract
Reactive oxygen species (ROS) are produced under normal physiological conditions and may have beneficial and harmful effects on biological systems. ROS are involved in many physiological processes such as differentiation, proliferation, necrosis, autophagy, and apoptosis by acting as signaling molecules or regulators of transcription factors. In this case, maintaining proper cellular ROS levels is known as redox homeostasis. Oxidative stress occurs because of the imbalance between the production of ROS and antioxidant defenses. Sources of ROS include the mitochondria, auto-oxidation of glucose, and enzymatic pathways such as nicotinamide adenine dinucleotide phosphate reduced (NAD[P]H) oxidase. The possible ROS pathways are NF-κB, MAPKs, PI3K-Akt, and the Keap1-Nrf2-ARE signaling pathway. This review covers the literature pertaining to the possible ROS pathways and strategies to inhibit them. Additionally, this review summarizes the literature related to finding ROS inhibitors.

Chin Med 2024; 19:10. [PMID: 38229198 DOI: 10.1186/s13020-024-00882-5] [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: 10/31/2023] [Accepted: 01/01/2024] [Indexed: 01/18/2024] Open
Abstract
BACKGROUND Qing-Zao-Jiu-Fei Decoction (QZJFD) is a famous herbal formula commonly prescribed for the treatment of lung-related diseases in the ancient and modern times. Trichosanthis Fructus (TF) and Fritillariae Thunbergii Bulbus (FTB) are widely used for treatment of cough and pulmonary disease. In order to identify a more effective formula for treatment of pulmonary fibrosis, we intend to add TF and FTB in QZJFD to form a modified QZJFD (MQZJFD). In this study, we aims to explore MQZJFD as an innovative therapeutic agent for pulmonary fibrosis using bleomycin (BLM)-treated rats and to unravel the underlying molecular mechanisms. METHODS BLM was given to SD rats by intra-tracheal administration of a single dose of BLM (5 mg/kg). QZJFD (3 g/kg) and MQZJFD (1, 2 and 4 g/kg) was given intragastrically daily to rats for 14 days (from day 15 to 28) after BLM administration for 14 consecutive days. RESULTS MQZJFD was found to contain 0.29% of amygdalin, 0.020% of lutin, 0.077% of glycyrrhizic acid and 0.047% of chlorogenic acid. BLM treatment could induce collagen deposition in the lung tissues of rats, indicating that the pulmonary fibrosis rat model had been successfully established. MQZJFD have better effects than the original QZJFD in reducing the pulmonary structure damage and collagen deposition of rat lung fibrosis induced by BLM. MQZJFD could reduce the hydroxyproline content in lung tissues of BLM-treated rats. The biomarkers of fibrosis such as matrix metalloproteinase 9 (MMP9), collagen I and α-smooth muscle actin (α-SMA) were remarkably reduced after treatment with MQZJFD. MQZJFD also have anti-oxidant stress effects by inhibiting the level of malondialdehyde (MDA), but enhancing the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and the level of glutathione (GSH) in the lung tissues of BLM-treated rats. Moreover, the MQZJFD markedly suppressed the over expressions of p-p65/p65 and p-IκBα/IκBα, but upregulated the Nrf2. MQZJFD also suppressed the protein expressions of p-ERK1/2/ERK1/2, p-p38/p38 and p-JNK/JNK in the lung tissues of BLM-treated rats. CONCLUSIONS MQZJFD could improve the pulmonary fibrosis induced by BLM in rats via inhibiting the fibrosis and oxidative stress via suppressing the activation of NF-κB/Nrf2 and MAPKs pathways.

Abstract
Currently, skin injuries have a serious impact on people's lives and socio-economic stress. Shikonin, a naphthoquinone compound derived from the root of the traditional Chinese medicine Shikonin, has favorable biological activities such as anti-inflammatory, antibacterial, immunomodulatory, anticancer, and wound-healing-promoting pharmacological activities. It has been reported that Shikonin can be used for repairing skin diseases due to its wide range of pharmacological effects. Moreover, the antimicrobial activity of Shikonin can play a great role in food and can also reduce the number of pathogenic bacteria in food. This paper summarizes the research on the pharmacological effects of Shikonin in recent years, as well as research on the mechanism of action of Shikonin in the treatment of certain skin diseases, to provide certain theoretical references for the clinical application of Shikonin, and also to provides research ideas for the investigation of the mechanism of action of Shikonin in other skin diseases.

Abstract
Small cell lung cancer (SCLC) is a subtype of lung cancer with a very poor overall survival rate due to its extremely high proliferation and metastasis predilection. Shikonin is an active ingredient extracted from the roots of Lithospermum erythrorhizon, and exerts multiple anti-tumor functions in many cancers. In the present study, the role and underlying mechanism of shikonin in SCLC were investigated for the first time. We found that shikonin effectively suppressed cell proliferation, apoptosis, migration, invasion, and colony formation and slightly induced apoptosis in SCLC cells. Further experiment indicated the shikonin could also induced ferroptosis in SCLC cells. Shikonin treatment effectively suppressed the activation of ERK, the expression of ferroptosis inhibitor GPX4, and elevated the level of 4-HNE, a biomarker of ferroptosis. Both total ROS and lipid ROS were increased, while the GSH levels were decreased in SCLC cells after shikonin treatment. More importantly, our data identified that the function of shikonin was dependent on the up-regulation of ATF3 by performing rescue experiments using shRNA to silence the expression of ATF3, especially in the total and lipid ROS accumulaiton. Xenograft model was established using SBC-2 cells, and the results revealed that shikonin also significantly inhibited tumor growth by inducing ferroptosis. Finally, our data further confirmed that shikonin activated ATF3 transcription by impairing the recruitment of HDAC1 mediated by c-myc on the ATF3 promoter, and subsequently elevating of histone acetylation. Our data documented that shikonin suppressed SCLC by inducing ferroptosis in a ATF3-dependent manner. Shikonin upregulated the expression of ATF3 expression via promoting the histone acetylation by inhibiting c-myc-mediated HDAC1 binding on ATF3 promoter.

Abstract
Introduction: Alkaloids derived from M. cordata (Papaveraceae family), have been found to display antineoplastic activity in several types of cancer. However, the antitumor effects and mechanisms of a new alkaloid extracted from the fruits of M. cordata, named 6-Methoxydihydroavicine (6-ME), remains unclear in the case of ovarian cancer (OC). Methods: CCK-8 assay was employed to analyze the cell viabilities of OC cells. RTCA, and colony-formation assays were performed to measure OC cell growth. Alterations in apoptosis and ROS levels were detected by flow cytometry in accordance with the instructions of corresponding assay kits. A Seahorse XFe96 was executed conducted to confirm the effects of 6-ME on cellular bioenergetics. Western blot and q-RT-PCR were conducted to detect alterations in target proteins. The subcutaneous xenografted tumor model of OC was used to further validate the anti-tumor activity of 6-ME in vivo. Results: Here, we reported for the first time that 6-ME inhibits OC cells growth in vitro and in vivo. Meanwhile, we found that 6-ME showed great antineoplastic activities by disrupting mitochondria homeostasis and promoting apoptosis in OC cells. Further investigation of the upstream signaling of apoptosis revealed that 6-ME-triggered apoptosis was induced by reactive oxygen species (ROS)-mediated mitogen-activated protein kinase (MAPK) activation and mitochondria dysfunction in OC cells. Furthermore, we found oxaloacetic acid (OAA), a crucial metabolite has been proved to be related to NADPH production, can block the cytotoxicity and accumulation of ROS caused by 6-ME in OC cells. Discussion: In summary, our data show that 6-ME exhibits cytotoxicity to OC cells in a ROS-dependent manner by interrupting mitochondrial respiration homeostasis and inducing MAPK-mediated apoptosis. This evidence suggests that 6-ME is a promising remedy for OC intervention.

The GSTP1/MAPKs/BIM/SMAC modulatory actions of nitazoxanide: Bioinformatics and experimental evidence in subcutaneous solid Ehrlich carcinoma-inoculated mice. Life Sci 2023; 319:121496. [PMID: 36822315 DOI: 10.1016/j.lfs.2023.121496] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 02/05/2023] [Accepted: 02/08/2023] [Indexed: 02/25/2023]
Abstract
AIMS Ehrlich ascites carcinoma and its subcutaneous inoculated solid tumour form (SEC) are reliable models for chemotherapeutic molecular targets exploration. Novel chemotherapeutic approaches are identified as molecular targets for intrinsic apoptosis, like the modulation of the second mitochondria-derived activator of caspases (SMAC). SMAC is a physiological substrate of mitogen-activated protein kinases (MAPKs). Glutathione-S-transferase P1 (GSTP1) and its close association with MAPKs play an important role in malignant cell proliferation, metastasis, and resistance to chemotherapeutics. Nitazoxanide (NTZ) is an emerging cancer therapy and its targeted GSTP1 evidence remains a knowledge need. MAIN METHODS In the present mice-established SEC, the chemotherapeutic roles of oral NTZ (200 mg/kg/day) and 5-fluorouracil (5-FU; 20 mg/kg/day, intraperitoneally) regimens were evaluated by measuring changes in tumour mass, the tumour MAPKs, cytochrome c, Bcl-2 interacting mediator of cell death (BIM), and SMAC signalling pathway in addition to its molecular downstream; caspases 3 and 9. KEY FINDINGS Computational analysis for these target protein interactions showed direct-ordered interactions. After individual therapy with NTZ and 5-FU regimens, the histological architecture of the extracted tumour discs revealed decreases in viable tumour regions with significant necrosis surrounds. These findings were consistent with gross tumour sizes. Each separate regimen lowered the remarkable GSTP1 and elevated the low MAPKs expressions, cytochrome c, BIM, SMAC, and caspases 3, and 9 in EST tissues. SIGNIFICANCE The chemotherapeutic activity of NTZ in SEC was proven. Additionally, NTZ possesses a SMAC modulatory activity that, following thorough research, should be taken into consideration as a chemotherapeutic approach in solid tumours.

Shikonin reverses pyruvate kinase isoform M2-mediated propranolol resistance in infantile hemangioma through reactive oxygen species-induced autophagic dysfunction. Cancer Sci 2023; 114:806-821.

Abstract
Infantile hemangioma (IH) is the most common benign tumor in infancy. Propranolol, a nonselective β-adrenergic receptor blocker, is now the first-line therapy for IH. Recently, low sensitivity to propranolol therapy has become one major reason for the failure of IH treatment. However, the exact underlying mechanisms are yet to be fully elucidated. Here, we reported that pyruvate kinase isoform M2 (PKM2), an essential glycolytic enzyme, played a critical role in regulating the progression of IH and the therapeutic resistance of propranolol treatment. Shikonin reversed the propranolol resistance in hemangioma-derived endothelial cells and in hemangioma animal models. Moreover, shikonin combined with propranolol could induce excessive reactive oxygen species (ROS) accumulation and lead to autophagic dysfunction, which is essential for the enhanced therapeutic sensitivity of propranolol treatment. Taken together, our results indicated that PKM2 has a significant role in hemangiomas progression and therapeutic resistance; it could be a safe and effective therapeutic strategy for those hemangiomas with poor propranolol sensitivity combined with shikonin.

Abstract
The topoisomerases (TOPO) play indispensable roles in DNA metabolism, by regulating the topological state of DNA. Topoisomerase I and II are the well-established drug-targets for the development of anticancer agents and antibiotics. These drugs-targeting enzymes have been used to establish the relationship between drug-stimulated DNA cleavable complex formation and cytotoxicity. Some anticancer drugs (such as camptothecin, anthracyclines, mitoxantrone) are also widely used as Topo I and Topo II inhibitors, but the poor water solubility, myeloma suppression, dose-dependent cardiotoxicity, and multidrug resistance (MDR) limited their prolong use as therapeutics. Also, most of these agents displayed selective inhibition only against Topo I or II. In recent years, researchers focus on the design and synthesis of the dual Topo I and II inhibitors, or the discovery of the dual Topo I and II inhibitors from natural products. Shikonin (a natural compound with anthraquinone skeleton, isolated from the roots of Lithospermum erythrorhizon) has drawn much attention due to its wide spectrum of anticancer activities, especially due to its dual Topo inhibitive performance, and without the adverse side effects, and different kinds of shikonin derivatives have been synthesized as TOPO inhibitors for the development of anticancer agents. In this review, the progress of the shikonin and its derivatives together with their anticancer activities, anticancer mechanism, and their structure-activity relationship (SAR) was comprehensively summarized by searching the CNKI, PubMed, Web of Science, Scopus, and Google Scholar databases.

Abstract
BACKGROUND AND AIMS Monocarboxylate transporter (MCT) 4 is a high-affinity lactate transporter that is primarily involved in the maintenance of intracellular pH homeostasis and highly expressed in different tumors. However, the role of MCT4 in modulating immune responses against HCC remains unknown. APPROACH AND RESULTS In this study, we demonstrated that MCT4 was overexpressed in HCC, which was associated with poor prognosis in patients. Genetic or pharmacological inhibition of MCT4 using VB124 (a highly potent MCT4 inhibitor) suppressed HCC tumor growth in immunocompetent mice model by enhancing CD8 + T cell infiltration and cytotoxicity. Such improved immunotherapy response by MCT4 targeting was due to combined consequences characterized by the alleviated acidification of tumor microenvironment and elevated the chemokine (C-X-C motif) ligand (CXCL) 9/CXCL10 secretion induced by reactive oxygen species/NF-κB signaling pathway. Combining MCT4 inhibition improved the therapeutic benefit of anti-programmed cell death 1 immunotherapy in HCC and prolonged mice survival. Moreover, higher MCT4 expression was observed in tumor tissues from nonresponder patients with HCC receiving neoadjuvant therapy with toripalimab. CONCLUSIONS Our results revealed that lactate exportation by MCT4 has a tumor-intrinsic function in generating an immunosuppressive HCC environment and demonstrated the proof of the concept of targeting MCT4 in tailoring HCC immunotherapeutic approaches.

Abstract
Reactive oxygen species (ROS) scavenging therapy toward acute kidney injury (AKI) is promising, but no effective ROS scavenging drug has been developed yet. Moreover, cell-free DNA (cfDNA) is also involved in AKI, but the corresponding therapies have not been well developed. To tackle these challenges, Mn3O4 nanoflowers (Nfs) possessing both ROS and cfDNA scavenging activities were developed for better AKI protection as follows. First, Mn3O4 Nfs could protect HK2 cells through cascade ROS scavenging (dismutating ·O2- into H2O2 by superoxide dismutase-like activity and then decomposing H2O2 by catalase-like activity). Second, Mn3O4 Nfs could efficiently adsorb cfDNA and then decrease the inflammation caused by cfDNA. Combined, remarkable therapeutic efficacy was achieved in both cisplatin-induced and ischemia-reperfusion AKI murine models. Furthermore, Mn3O4 Nfs could be used for the T1-MRI real-time imaging of AKI. This study not only offered a promising treatment for AKI but also showed the translational potential of nanozymes.

Abstract
Multiple myeloma (MM) is an incurable hematological malignancy that lacks effective therapeutic interventions. Ferroptosis is a newly discovered form of cell death that has shown great potential for MM therapy. As a proteasome inhibitor and necroptosis inducer, shikonin (SHK) performs dual functions in MM cells. However, whether SHK inhibits the development of MM via ferroptosis or any other mechanism remains elusive. Here, we provide evidence that SHK treatment was capable of inducing ferroptosis and immunogenic cell death (ICD) in MM. The results showed that SHK treatment induced lactate dehydrogenase release, triggered cell death, evoked oxidative stress, and enhanced ferrous iron and lipid peroxidation levels. Furthermore, treatment with ferroptosis inhibitors reversed SHK-induced cell death, which indicated that ferroptosis contributed to this phenomenon. Meanwhile, ferroptosis was accompanied by the extracellular release of Adenosine 5'-triphosphate (ATP) and High mobility group protein B1 (HMGB1), which are characteristics of ICD. Further investigation showed that glutamic-oxaloacetic transaminase 1 (GOT1) acted as a critical mediator of SHK-induced ferroptosis by promoting ferritinophagy. In conclusion, our findings suggest that SHK exerts ferroptotic effects on MM by regulating GOT1-mediated ferritinophagy. Thus, SHK is a potential therapeutic agent for MM.

Abstract
Therapeutic targeting of leukemic stem cells is widely studied to control leukemia. An emerging approach gaining popularity is altering metabolism as a potential therapeutic opportunity. Studies have been carried out on hematopoietic and leukemic stem cells to identify vulnerable pathways without impacting the non-transformed, healthy counterparts. While many metabolic studies have been conducted using stem cells, most have been carried out in vitro or on a larger population of progenitor cells due to challenges imposed by the low frequency of stem cells found in vivo. This creates artifacts in the studies carried out, making it difficult to interpret and correlate the findings to stem cells directly. This review discusses the metabolic difference seen between hematopoietic stem cells and leukemic stem cells across different leukemic models. Moreover, we also shed light on the advancements of metabolic techniques and current limitations and areas for additional research of the field to study stem cell metabolism.

Abstract
c-Jun N-terminal kinases (JNKs), members of the mitogen-activated protein kinase (MAPK) family, are encoded by three genes: jnk1, jnk2, and jnk3. JNKs are involved in the pathogenesis and development of many diseases, such as neurodegenerative diseases, inflammation, and cancers. Therefore, JNKs have become important therapeutic targets. Many JNK inhibitors have been discovered, and some have been introduced into clinical trials. However, the study of isoform-selective JNK inhibitors is still a challenging task. To further develop novel JNK inhibitors with clinical value, a comprehensive understanding of JNKs and their corresponding inhibitors is required. In this Perspective, we introduced the JNK signaling pathways and reviewed different chemical types of JNK inhibitors, focusing on their structure-activity relationships and biological activities. The challenges and strategies for the development of JNK inhibitors are also discussed. It is hoped that this Perspective will provide valuable references for the development of novel selective JNK inhibitors.

Abstract
Most of the antitumor chemotherapeutic drugs execute the therapeutic performance upon eliciting tumor cell apoptosis, which may cause chemoresistance of tumors. Design of novel drugs to eradicate apoptosis-resistant tumors via non-apoptotic cell death pathways is promising for improving the long-term chemotherapeutic efficacy. Herein, a Fe(III)-Shikonin metal-polyphenol-coordinated supramolecular nanomedicine for combined therapy of tumor via ferroptosis and necroptosis is designed. The construction of the nanomedicine based on the coordinated self-assembly between Fe3+ and Shikonin not only overcomes the shortcomings of Shikonin including its low bioavailability and high toxicity toward normal tissues, but also integrates the theranostics functions of Fe ions. Under the exposure of the high concentration of glutathione (GSH) in tumor cells, the as-prepared nanomedicine will disassemble into Fe2+ and Shikonin, followed by stimulating the tumor cell death through ferroptosis and necroptosis. In addition, benefiting from the stealth effect of polyethylene glycol (PEG) and the targeting ability of cyclo(Arg-Gly-Asp-d-Phe-Lys) (cRGD) to αv β3 -integrin, NH2 -PEG-cRGD-modified nanomedicine exhibits a GSH-responsive therapy toward 4T1 tumor in vivo and self-enhanced longitudinal relaxation (T1 )-weighted imaging property. Since the self-assembly of natural Shikonin and human body-necessary Fe element is facile and feasible, the work may provide a promising supramolecular nanomedicine for next-generation chemotherapeutic applications.

The new andrographolide derivative AGS-30 induces apoptosis in human colon cancer cells by activating a ROS-dependent JNK signalling pathway. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 94:153824. [PMID: 34763314 DOI: 10.1016/j.phymed.2021.153824] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 10/04/2021] [Accepted: 10/19/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND The anti-cancer activity of andrographolide (Andro) has been extensively demonstrated in recent years. It is supposed that modifying the chemical structure of Andro can improve its efficacy and reduce its toxicity. PURPOSE In this study, the anti-cancer effect of a 14β-(2'-chlorophenoxy) derivative of andrographolide known as AGS-30 was investigated, and its underlying mechanisms were also explored. STUDY DESIGN/METHODS Different cancer cells were used to evaluate and compare the in vitro anti-cancer effects of Andro and AGS-30. Human colon cancer cells HT-29 and HCT-116 were used to study the underlying anti-cancer mechanisms of AGS-30. HT-29 cells xenografted in nude mouse model was used to compare the in vivo anti-tumour efficacies of Andro and AGS-30. RESULT In vitro studies showed that AGS-30 possessed an anti-cancer effect by inhibiting the viability, colony formation and migration of cancer cells. It significantly induced the generation of reactive oxygen species (ROS), caused the loss of mitochondrial membrane potential and triggered the apoptosis in colon cancer cells. These effects of AGS-30 were more potent than those of Andro. In addition, the expression levels of proteins associated with apoptosis, including phospho-JNK1/2 as well as cleaved caspase 9, caspase 3, and poly(ADP ribose) polymerase, were elevated in AGS-30-treated colon cancer cells. Moreover, these elevated levels of the proteins were inhibited by the antioxidant N-acetylcysteine and the JNK inhibitor SP600125, suggesting the involvement of ROS/JNK-dependent mechanisms in AGS-30-induced apoptosis. The in vitro anti-cancer effect could be reproduced in an HT-29 colon cancer cell xenografted nude mouse model. CONCLUSION The anti-cancer effect of AGS-30 is stronger than that of Andro. AGS-30 induces apoptosis of colon cancer cells through ROS/JNK-dependent pathway. Our findings may provide insights for the future development of derivatives of Andro as novel chemotherapeutic agents.

Abstract
Unique phytochemical profile of plants belonging to Boraginaceae family provides a prolific resource of lipophilic pigments from the group of naphthoquinone derivatives. To overcome low compound content, the major obstacle of plant-based production, immobilization of Rindera graeca roots in in vitro cultures was implemented for efficient production of rinderol, novel furanonaphthoquinone derivative with anticancer properties. Chromatographic procedures revealed rinderol presence in extracts of all investigated root lines, derived both from root biomass and post-culture medium. Unexpectedly, in the second stage of the experiment, rinderol production was ceased in control, unmodified culture systems. On the contrary, roots immobilized on PUF rafts uniformly and stably produced rinderol, and its highest amount was noted for transformed root lines after 42 days of cultivation (222.98 ± 10.47 µg/flask). PUF occurred to be the main place of compound accumulation. Moreover, investigation of rinderol biological activity revealed its fast-acting cell death induction in HeLa cervical cancer cells at relatively low concentrations. Presented results revealed successful application of R. graeca roots immobilization on PUF rafts for production and in situ product removal of rinderol, novel lipophilic furanonaphthoquinone with suggested proapoptotic activity.

Abstract
Uveal melanoma (UM) is the most common ocular malignancy and has no effective clinical treatment. Therefore, novel drugs to suppress UM tumor progression are urgently required. The present study aimed to clarify the underlying mechanism of the inhibitory effects of artesunate on UM. By using plasmid transfection and detecting apoptotic level, the present study identified artesunate as a potential candidate for UM treatment. Compared with those in the vehicle (DMSO)-treated control cells, artesunate enhanced the apoptotic rate and increased lactate dehydrogenase release, reactive oxygen species and IL1b and IL18 levels in C918 cells. Overexpression of yes-associated protein (YAP) or metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in C918 cells reversed the effects of artesunate and reduced the apoptotic rate compared with those observed in cells transfected with the negative control plasmid. Notably, verteporfin enhanced the effects of artesunate on C918 cells by increasing the apoptotic rate, indicating that combined therapy was more effective compared with treatment with artesunate alone. In conclusion, the results of the present study demonstrated that artesunate elevated the apoptotic rate and suppressed C918 cell viability by regulating the MALAT1/YAP signaling pathway, and these effects were enhanced by supplementation with verteporfin. These results suggested that artesunate may exert an inhibitory effect on C918 cells and that the MALAT1/YAP signaling may serve important role in mediating these effects, providing evidence of its potential for treating UM in the clinic.

NR4A1 enhances MKP7 expression to diminish JNK activation induced by ROS or ER-stress in pancreatic β cells for surviving. Cell Death Discov 2021; 7:133. [PMID: 34088892 PMCID: PMC8178316 DOI: 10.1038/s41420-021-00521-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 04/18/2021] [Accepted: 05/13/2021] [Indexed: 12/03/2022] Open
Abstract
Under adverse conditions, such as sustained or chronic hyperglycemia or hyperlipidemia, ROS (reactive oxygen species) or/and ER-stress (endoplasmic reticulum stress) will be induced in pancreatic β cells. ROS or ER-stress damages β-cells even leads to apoptosis. Previously we found ROS or ER-stress resulted in JNK activation in β cells and overexpressing NR4A1 in MIN6 cells reduced JNK activation via modulating cbl-b expression and subsequent degrading the upstream JNK kinase (MKK4). To search other possible mechanisms, we found the mRNA level and protein level of MKP7 (a phosphatase for phospho-JNK) were dramatic reduced in pancreatic β cells in the islets from NR4A1 KO mice compared with that from wild type mice. To confirm what we found in animals, we applied pancreatic β cells (MIN6 cells) and found that the expression of MKP7 was increased in NR4A1-overexpression MIN6 cells. We further found that knocking down the expression of MKP7 increased the p-JNK level in pancreatic β cells upon treatment with TG or H2O2. After that, we figured out that NR4A1 did enhance the transactivation of the MKP7 promoter by physical association with two putative binding sites. In sum, NR4A1 attenuates JNK phosphorylation incurred by ER-stress or ROS partially via enhancing MKP7 expression, potentially decreases pancreatic β cell apoptosis induced by ROS or ER-stress. Our finding provides a clue for diabetes prevention.

Abstract
Propyl gallate (PG) has an anti-growth effect in lung cancer cells. The present study investigated the effects of mitogen-activated protein kinase (MAPK; MEK, JNK, and p38) inhibitors on PG-treated Calu-6 and A549 lung cancer cells in relation to cell death as well as reactive oxygen species (ROS) and glutathione (GSH) levels. PG induced cell death in both Calu-6 and A549 lung cancer cells at 24 h, which was accompanied by loss of mitochondrial membrane potential (MMP; ΔΨm). All of the tested MAPK inhibitors increased cell death in both PG-treated lung cancer cell lines. In particular, MEK inhibitor strongly enhanced cell death and MMP (ΔΨm) loss in PG-treated Calu-6 cells and p38 inhibitor had the same effects in A549 cells as well. PG increased ROS levels and caused GSH depletion in both cell lines at 24 h. MAPK inhibitors increased O2•- levels and GSH depletion in PG-treated Calu-6 cells, and JNK and p38 inhibitors increased ROS levels and GSH depletion in PG-treated A549 cells. In conclusion, MAPK inhibitors increased cell death in PG-treated Calu-6 and A549 lung cancer cells. Enhanced cell death and GSH depletion in Calu-6 cells caused by the MEK inhibitor were related to increased O2•- levels, and the effects of the p38 inhibitor in A549 cells were correlated with increased general ROS levels.

Abstract
Antitumor effects of shikonins on chronic lymphocytic leukemia (CLL) and B-cell prolymphocytic leukemia (B-PLL) are mostly unexplored. The antitumor activity of shikonins, isolated from Onosma visianii Clem (Boraginaceae), in BCL1, mouse CLL cells and JVM-13, human B-PLL cells was explored in this study. The cytotoxicity of shikonin derivatives was measured by an MTT test. Cell death, proliferation, cell cycle, and expression of molecules that control these processes were analyzed by flow cytometry. Expression of STAT3-regulated genes was analyzed by real-time q-RT-PCR (Quantitative Real-Time Polymerase Chain Reaction). The antitumor effects of shikonin derivatives in vivo were analyzed, using flow cytometry, by detection of leukemia cells in the peripheral blood and spleens of mice intravenously injected with BCL1 cells. The two most potent derivatives, isobutyrylshikonin (IBS) and α-methylbutyrylshikonin (MBS), induced cell cycle disturbances and apoptosis, inhibited proliferation, and decreased expression of phospho-STAT3 and downstream-regulated molecules in BCL1 and JVM-13 cells. IBS and MBS decreased the percentage of leukemia cells in vivo. The link between the decrease in phosphorylated STAT3 by MBS and IBS and BCL1 cell death was confirmed by detection of enhanced cell death after addition of AG490, an inhibitor of Jak2 kinase. It seems that IBS and MBS, by decreasing STAT3 phosphorylation, trigger apoptosis, inhibit cell proliferation, and attenuate leukemia cell stemness.

Abstract
Lichens are the symbiotic association between photobiont algae and mycobiont fungi having diverse phytochemicals. However, they are still an underexplored natural resource for biological activities. In the present report, we have evaluated the anti-brain and anti-cervical cancer activity of tropical lichen, Dirinaria consimilis (DCME) through the cell viability assay, cell cycle analysis, annexin V-FLUOS staining, morphological analysis, ROS-induction mechanism, evaluation of antioxidant levels, and western blotting study. The WST-1-based cell viability assay showed the cytotoxic nature of DCME towards U87 (IC50-52.65 ± 1.04 µg/ml) and HeLa (IC50-77.60 ± 2.23 µg/ml) cells. Interestingly, DCME does not showed any toxicity towards non-malignant fibroblast cell line WI-38 (IC50-685.80 ± 19.51 µg/ml). Furthermore, the cell cycle analysis showed sub-G1 arrest (apoptosis), and annexin V-FLUOS staining showed an increase in early apoptosis population dose-dependently. Confocal-based morphological data confirmed the DNA condensation and fragmentation upon treatment. Furthermore, DCME treatment induces ROS and regulates the levels of antioxidant enzymes (SOD, Catalase, GST, and GSH) in both U87 and HeLa cells. Finally, the western blotting data revealed the increase in Bax/Bcl-2 ratio, activation of Bid, Caspase-8, -9 and -3 along with degradation of PARP. Moreover, regulation of MAP kinases and activation of p53 was also observed upon DCME treatment. Herein, we first reported the anticancer activity of D. consimilis against brain and cervical cancer cells. Performed in-depth anticancer study revealed the ROS-mediated regulation of MAP kinases and activation of caspase cascade in U87 and HeLa cells upon DCME treatment.

Abstract
Mitochondria are the cellular powerhouses that generate adenosine triphosphate (ATP) to substantiate various biochemical activities. Instead of being a static intracellular structure, they are dynamic organelles that perform constant structural and functional remodeling in response to different metabolic stresses. In situations that require a high ATP supply, new mitochondria are assembled (mitochondrial biogenesis) or formed by fusing the existing mitochondria (mitochondrial fusion) to maximize the oxidative capacity. On the other hand, nutrient overload may produce detrimental metabolites such as reactive oxidative species (ROS) that wreck the organelle, leading to the split of damaged mitochondria (mitofission) for clearance (mitophagy). These vital processes are tightly regulated by a sophisticated quality control system involving energy sensing, intracellular membrane interaction, autophagy, and proteasomal degradation to optimize the number of healthy mitochondria. The effective mitochondrial surveillance is particularly important to skeletal muscle fitness because of its large tissue mass as well as its high metabolic activities for supporting the intensive myofiber contractility. Indeed, the failure of the mitochondrial quality control system in skeletal muscle is associated with diseases such as insulin resistance, aging, and muscle wasting. While the mitochondrial dynamics in cells are believed to be intrinsically controlled by the energy content and nutrient availability, other upstream regulators such as hormonal signals from distal organs or factors generated by the muscle itself may also play a critical role. It is now clear that skeletal muscle actively participates in systemic energy homeostasis via producing hundreds of myokines. Acting either as autocrine/paracrine or circulating hormones to crosstalk with other organs, these secretory myokines regulate a large number of physiological activities including insulin sensitivity, fuel utilization, cell differentiation, and appetite behavior. In this article, we will review the mechanism of myokines in mitochondrial quality control and ROS balance, and discuss their translational potential.

Shikonin inhibits proliferation of melanoma cells by MAPK pathway-mediated induction of apoptosis. Biosci Rep 2021; 41:227495. [PMID: 33403388 PMCID: PMC7823184 DOI: 10.1042/bsr20203834] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2020] [Revised: 12/28/2020] [Accepted: 01/05/2021] [Indexed: 01/04/2023] Open
Abstract
Shikonin, a natural product isolated from the roots of Lithospermum erythrorhizon, exhibits pharmacological effects against inflammation, ulcers, infections, and tumors. In the present study, we aimed to investigate the antitumor effects of shikonin on the human melanoma cell line, A375SM, and in an in vivo mouse xenograft model. We examined the anticancer effects of shikonin by in vitro experiments (MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, 4′,6-diamidino-2-phenylindole (DAPI) stain, annexin V/ propidium iodide (PI) stain, and protein analysis of apoptosis and mitogen-activated protein kinase (MAPK) pathways). Further, the anticancer effect in vivo was confirmed through a xenograft model. Our results showed that shikonin inhibited the proliferation of melanoma cells in a dose-dependent manner. In addition, shikonin significantly increased nucleus and chromatin condensation and early/late apoptosis. Shikonin also increased the pro-apoptotic proteins and decreased the anti-apoptotic proteins. Additionally, shikonin was overexpressed in MAPK pathways. Investigation of the effects of shikonin in a mouse xenograft model not only showed decreased A375SM tumor volume but also increased apoptosis as determined by terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay. Furthermore, pathologic changes were not observed in the liver and kidney of mice. Collectively, the study indicated that shikonin inhibited the proliferation of the human melanoma cells by inducing apoptosis, mediated by MAPK pathway and that it is a potential candidate for an anticancer drug against melanoma cancer.

Alam MM, Kariya R, Boonnate P, Kawaguchi A, Okada S. Induction of apoptosis by Shikonin through ROS-mediated intrinsic and extrinsic apoptotic pathways in primary effusion lymphoma. Transl Oncol 2021; 14:101006. [PMID: 33401054 PMCID: PMC7785961 DOI: 10.1016/j.tranon.2020.101006] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 12/16/2020] [Accepted: 12/27/2020] [Indexed: 01/29/2023] Open
Abstract
Shikonin (SHK) induced apoptosis in Primary effusion lymphoma (PEL). SHK treatment rabidly generated ROS and activated JNK and p38. SHK inhibited ascites formation in xenograft mice.
Primary effusion lymphoma (PEL) is an incurable non-Hodgkin's lymphoma and novel biology-based treatments are urgently needed in clinical settings. Shikonin (SHK), a napthoquinone derivative, has been used for the treatment of solid tumors. Here, we report that SHK is an effective agent for the treatment of PEL. Treatment with SHK results in significant reduction of proliferation in PEL cells and their rapid apoptosis in vitro. SHK-induced apoptosis of PEL cells is accompanied by the generation of reactive oxygen species (ROS), loss of mitochondrial membrane potential (Δψm), an activation of c-Jun-N-terminal kinase (JNK), p38, as well as caspase-3, -8, and -9. Scavenging of ROS in the presence of N-acetylcysteine (NAC) almost blocks the loss of mitochondrial membrane Δψm, activation of JNK, cleavage of caspase-3, -9, and an induction of apoptosis in SHK treated PEL cells. SP600125, a specific inhibitor of JNK, also rescues a proportion of cells from the apoptotic effect of SHK. In addition, inhibition of caspase activation in the presence of pan-caspase inhibitor, Q-VD-OPh, blocks the SHK-inducing apoptosis, but doesn't completely inhibit SHK-mediated JNK activation. Therefore, ROS is an upstream trigger of SHK-induced caspase dependent apoptosis of PEL cells through disruption of mitochondrial membrane Δψm in an intrinsic pathway and an activation of JNK in an extrinsic pathway. In a PEL xenografted mouse model, SHK treatment suppresses PEL-mediated ascites formation without showing any significant adverse toxicity. These results suggested that SHK could be a potent anti-tumor agent for the treatment of PEL.

Abstract
Sustained hyperglycaemia and hyperlipidaemia incur endoplasmic reticulum stress (ER stress) and reactive oxygen species (ROS) overproduction in pancreatic β‐cells. ER stress or ROS causes c‐Jun N‐terminal kinase (JNK) activation, and the activated JNK triggers apoptosis in different cells. Nuclear receptor subfamily 4 group A member 1 (NR4A1) is an inducible multi‐stress response factor. The aim of this study was to explore the role of NR4A1 in counteracting JNK activation induced by ER stress or ROS and the related mechanism. qPCR, Western blotting, dual‐luciferase reporter and ChIP assays were applied to detect gene expression or regulation by NR4A1. Immunofluorescence was used to detect a specific protein expression in β‐cells. Our data showed that NR4A1 reduced the phosphorylated JNK (p‐JNK) in MIN6 cells encountering ER stress or ROS and reduced MKK4 protein in a proteasome‐dependent manner. We found that NR4A1 increased the expression of cbl‐b (an E3 ligase); knocking down cbl‐b expression increased MKK4 and p‐JNK levels under ER stress or ROS conditions. We elucidated that NR4A1 enhanced the transactivation of cbl‐b promoter by physical association. We further confirmed that cbl‐b expression in β‐cells was reduced in NR4A1‐knockout mice compared with WT mice. NR4A1 down‐regulates JNK activation by ER stress or ROS in β‐cells via enhancing cbl‐b expression.

Abstract
BACKGROUND Arnebia euchroma (A. euchroma) is a traditional Chinese medicine (TCM) used for the treatment of blood diseases including leukemia. In recent years, many studies have been conducted on the anti-tumor effect of shikonin and its derivatives, the major active components of A. euchroma. However, the underlying mechanism of action (MoA) for all the components of A. euchroma on leukemia has not been explored systematically. METHODS In this study, we analyzed the MoA of A. euchroma on leukemia via network pharmacology approach. Firstly, the chemical components and their concentrations in A. euchroma as well as leukemia-related targets were collected. Next, we predicted compound-target interactions (CTIs) with our balanced substructure-drug-target network-based inference (bSDTNBI) method. The known and predicted targets of A. euchroma and leukemia-related targets were merged together to construct A. euchroma-leukemia protein-protein interactions (PPIs) network. Then, weighted compound-target bipartite network was constructed according to combination of eight central attributes with concentration information through Cytoscape. Additionally, molecular docking simulation was performed to calculate whether the components and predicted targets have interactions or not. RESULTS A total of 65 components of A. euchroma were obtained and 27 of them with concentration information, which were involved in 157 targets and 779 compound-target interactions (CTIs). Following the calculation of eight central attributes of targets in A. euchroma-leukemia PPI network, 37 targets with all central attributes greater than the median values were selected to construct the weighted compound-target bipartite network and do the KEGG pathway analysis. We found that A. euchroma candidate targets were significantly associated with several apoptosis and inflammation-related biological pathways, such as MAPK signaling, PI3K-Akt signaling, IL-17 signaling, and T cell receptor signaling pathways. Moreover, molecular docking simulation demonstrated that there were eight pairs of predicted CTIs had the strong binding free energy. CONCLUSIONS This study deciphered that the efficacy of A. euchroma in the treatment of leukemia might be attributed to 10 targets and 14 components, which were associated with inhibiting leukemia cell survival and inducing apoptosis, relieving inflammatory environment and inhibiting angiogenesis.

Abstract
Hematopoietic gene delivery, such as hematopoietic stem/progenitor cells (HSPCs), is a promising treatment for both inherited and acquired diseases, such as hemophilia. Recently, a combined strategy to achieve more than 90% transduction efficiency was documented using recombinant adeno-associated virus serotype 6 (rAAV6) vectors. However, the mechanisms of enhanced vector transduction efficiency in hematopoietic cells are largely unknown. In this manuscript, we first reported that proteasome inhibitors, which are well-known to facilitate rAAV intracellular trafficking in various cell types, are not effective in hematopoietic cells. From the screening of small molecules derived from traditional Chinese medicine, we demonstrated that shikonin, a potential reactive oxygen species (ROS) generator, significantly increased the in vitro and ex vivo transgene expression mediated by rAAV6 vectors in hematopoietic cells, including human cord blood-derived CD34 + HSPCs. Shikonin mainly targeted vector intracellular trafficking, instead of host cell entry or endonuclear single to double strand vector DNA transition, in a vector serotype-dependent manner. Moreover, a ROS scavenger completely prevented the capability of shikonin to enhance rAAV6 vector-mediated transgene expression. Taken together, these studies expand our understanding of rAAV6-mediated transduction in hematopoietic cells and are informative for improving rAAV6-based treatment of blood diseases.

Aging (Albany NY) 2020; 12:17662-17680.

Abstract
Development of resistance to tyrosine kinase inhibitors (TKIs) targeting the BCR/ABL fusion protein represents a major challenge in the treatment of chronic myeloid leukemia (CML). Since apoptosis resistance is the fundamental mechanism impeding TKIs' therapeutic effects, alternative approaches that induce nonapoptotic cell death are being pursued to treat TKI-resistant CML. Induction of necroptosis, a distinct, caspase-independent form of programmed cell death, may be a valuable strategy in this respect. The present study shows that shikonin, an herbal compound used in traditional Chinese medicine, overcomes TKI resistance in BCR/ABL-positive CML cells by inducing necroptosis via activation of RIPK1/RIPK3/MLKL signaling. This effect occurs both in vitro and in vivo and involves downregulation of miR-92a-1-5p, a poor-prognosis marker frequently overexpressed in leukemia patients. Based on gene expression experiments, we conclude that miR-92a-1-5p promotes CML progression by inhibiting MLKL expression. Accordingly, we show that antagomiR-mediated in vivo inhibition of miR-92a-1-5p reduces the growth of CML tumors in mice through necroptosis induction. Our research suggests that therapies that relieve MLKL suppression by targeting miR-92a-1-5p may represent a useful strategy to treat TKI-refractory CML.

Abstract
Triple-negative breast cancer (TNBC) is heterogeneous disease with a poor prognosis. It is therefore important to explore novel therapeutic agents to improve the clinical efficacy for TNBC. The inosine 5'-monophosphate dehydrogenase 2 (IMPDH2) is a rate-limiting enzyme in the de novo synthesis of guanine nucleotides. It is always overexpressed in many types of tumors, including TNBC and regarded as a potential target for cancer therapy. Through screening a library of natural products, we identified shikonin, a natural bioactive component of Lithospermum erythrorhizon, is a novel and selective IMPDH2 inhibitor. Enzymatic analysis using Lineweaver-Burk plot indicates that shikonin is a competitive inhibitor of IMPDH2. The interaction between shikonin and IMDPH2 was further investigated by thermal shift assay, fluorescence quenching, and molecular docking simulation. Shikonin treatment effectively inhibits the growth of human TNBC cell line MDA-MB-231, and murine TNBC cell line, 4T1 in a dose-dependent manner, which is impaired by exogenous supplementation of guanosine, a salvage pathway of purine nucleotides. Most importantly, IMPDH2 knockdown significantly reduced cell proliferation and conferred resistance to shikonin in TNBC. Collectively, our findings showed the natural product shikonin as a selective inhibitor of IMPDH2 with anti-TNBC activity, impelling its further study in clinical trials.

Abstract
BACKGROUND Acute myeloid leukemia (AML) is a heterogenous hematological malignancy with poor long-term survival. New drugs which improve the outcome of AML patients are urgently required. In this work, the activity and mechanism of action of the cytotoxic indole alkaloid Jerantinine B (JB), was examined in AML cells. METHODS We used a combination of proliferation and apoptosis assays to assess the effect of JB on AML cell lines and patient samples, with BH3 profiling being performed to identify early effects of the drug (4 h). Phosphokinase arrays were adopted to identify potential driver proteins in the cellular response to JB, the results of which were confirmed and extended using western blotting and inhibitor assays and measuring levels of reactive oxygen species. RESULTS AML cell growth was significantly impaired following JB exposure in a dose-dependent manner; potent colony inhibition of primary patient cells was also observed. An apoptotic mode of death was demonstrated using Annexin V and upregulation of apoptotic biomarkers (active caspase 3 and cleaved PARP). Using BH3 profiling, JB was shown to prime cells to apoptosis at an early time point (4 h) and phospho-kinase arrays demonstrated this to be associated with a strong upregulation and activation of both total and phosphorylated c-Jun (S63). The mechanism of c-Jun activation was probed and significant induction of reactive oxygen species (ROS) was demonstrated which resulted in an increase in the DNA damage response marker γH2AX. This was further verified by the loss of JB-induced C-Jun activation and maintenance of cell viability when using the ROS scavenger N-acetyl-L-cysteine (NAC). CONCLUSIONS This work provides the first evidence of cytotoxicity of JB against AML cells and identifies ROS-induced c-Jun activation as the major mechanism of action.

Abstract
Background The Philadelphia chromosome (Ph), which leads to the creation and expression of the fusion gene product BCR-ABL, underlines the pathogenesis of chronic myelogenous leukemia (CML) and a fraction of adult and pediatric acute B-lymphoblastic leukemia (B-ALL). The BCR-ABL tyrosine kinase inhibitors (TKIs) have shown a remarkable clinical activity in patients with CML, but their efficacy in treating Ph+ B-ALL is limited. Identifying additional therapeutic targets is important for the effective treatment of Ph+ B-ALL. Methods Activation of the JNK signaling pathway in human and mouse BCR-ABL+ B-ALL cells with or without dasatinib treatment was analyzed by Western blotting. JNK was inhibited either by RNA interference or chemical inhibitors, such as JNK-IN-8. The effect of JNK inhibition with or without BCR-ABL TKI dasatinib on BCR-ABL+ B-ALL cells was analyzed by the CellTiter-Glo® Luminescent Cell Viability Assay. The in vivo effects of JNK-IN-8 and dasatinib alone or in combination were tested using a BCR-ABL induced B-ALL mouse model. Results We found that the c-JUN N-terminal kinase (JNK) signaling pathway is abnormally activated in both human and mouse BCR-ABL+ B-ALL cells, but the BCR-ABL TKI does not inhibit JNK activation in these cells. Inhibition of JNK, either by RNAi-mediated downregulation or by JNK inhibitors, could significantly reduce viability of Ph+ B-ALL cells. JNK inhibition by RNAi-mediated downregulation or JNK inhibitors also showed a synergistic effect with the BCR-ABL TKI, dasatinib, in killing Ph+ B-ALL cells in vitro. Furthermore, a potent JNK inhibitor, JNK-IN-8, in combination with dasatinib markedly improved the survival of mice with BCR-ABL induced B-ALL, as compared to the treatment with dasatinib alone. Conclusions Our findings indicate that simultaneously targeting both BCR-ABL and JNK kinase might serve as a promising therapeutic strategy for Ph+ B-ALL.

Abstract
Shikonin is a natural naphthoquinone compound and has demonstrated potent anti-cancer activities; however, the underlying molecular mechanisms remained elusive. Here we report that Shikonin inhibited the growth of a wide range of human cancer cell lines, illustrating a broad anticancer effect. Mechanistically, we show that Shikonin arrested the cell cycle at the G2/M phase, inhibited the ERK-dependent cell growth signal, and induced cell death in both P53 wild type and mutant cancer cells, which collectively contributed to the growth inhibitory effect of Shikonin. A pan-apoptosis inhibitor largely suppressed Shikonin-induced cell death, suggesting an important role of apoptosis in this process. Intriguingly, Shikonin also activated autophagy and inhibition of autophagy by depleting critical autophagic genes further increased Shikonin-induced cell death, indicating a protective role of autophagy. In uncovering the molecular mechanisms underlying these effects of Shikonin, we found that Shikonin induced a robust upregulation of P21 independent of the P53 status, upregulated autophagy genes, as well as inhibited expression of genes required for cell growth. Using mouse tumor models, we confirmed the strong anticancer effect of Shikonin in vivo. Together, our data reveal a broad range of pharmacological functions of Shikonin, involving simultaneous growth inhibition, cell cycle arrest, autophagy activation and apoptosis induction through regulating expression of critical genes involved in these pathways. Our study may facilitate the development of Shikonin in cancer therapy as a single agent or in combination with other anticancer therapies.

Isobutyrylshikonin has a potentially stronger cytotoxic effect in oral cancer cells than its analogue shikonin in vitro. Arch Oral Biol 2020; 116:104774.

Abstract
OBJECTIVES The aim of the present study was to identify the anticancer effects and the mechanisms of action of shikonin and its analogue isobutyrylshikonin in oral squamous carcinoma cells. DESIGNS The cytotoxic effects of isobutyrylshikonin and shikonin in Ca9-22 and SCC-25 cells were analyzed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, flow cytometry analysis of Annexin V/Propidium Iodide (PI) staining, western blot analysis and immunohistochemistry. RESULTS Treatment with both isobutyrylshikonin and shikonin induced dose- and time-dependent apoptotic cell death in Ca9-22 cells, although the IC50 of isobutyrylshikonin was less than that of shikonin. The induction of apoptosis by both isobutyrylshikonin and shikonin was accompanied by activation of caspase-8, -9, -3, and PARP, loss of mitochondrial trans-membrane potential, and release of cytochrome c from the mitochondria. ROS mediated the apoptosis induced by isobutyrylshikonin and shikonin, indicating that ROS may play a critical role in the distinctive cytotoxic effects of isobutyrylshikonin and shikonin in Ca9-22. Isobutyrylshikonin showed a similar cytotoxic effect in SCC-25 cells at concentrations showing the effects in Ca9 cells, but not in human normal keratinocyte cells. Although there is no biological difference between isobutyrylshikonin and shikonin, isobutyrylshikonin exerts the same cytotoxic effect at a concentration 6 times lower than shikonin. CONCLUSIONS The present study suggest that isobutyrylshikonin may be a more potent chemotherapeutic agent against oral cancer cells than shikonin. In addition, our data exhibit that both isobutyrylshikonin and shikonin induce caspase-dependent apoptosis via the mitochondrial pathway through accumulation of ROS in oral squamous carcinoma cells.

Aluminum trichloride caused hippocampal neural cells death and subsequent depression-like behavior in rats via the activation of IL-1β/JNK signaling pathway. THE SCIENCE OF THE TOTAL ENVIRONMENT 2020; 715:136942.

Abstract
Aluminum (Al) is an inorganic pollutant that induces nerve cells apoptosis and necroptosis, thereby causing depression and neurodegenerative diseases. IL-1β/JNK signaling pathway can regulate apoptosis and necroptosis. However, it remains unclear whether IL-1β/JNK signaling pathway is involving in the regulation of Al-induced hippocampal neural cells apoptosis and necroptosis. To investigate the mechanism of Al on neural cells apoptosis and necroptosis, rats were orally exposed to different doses of AlCl3 for 90 days. The open-field test results showed that AlCl3 caused depressive behavior in rats. Histopathological evidence showed that AlCl3 induced hippocampal neural cells apoptosis and necrosis. Moreover, Bax/Bcl-2 mRNA expression ratio, caspase-3 activity and mRNA expression and TUNEL positive rates were upregulated, meanwhile, TNF-α mRNA and protein expression levels, TNFR1, RIP1, RIP3 and MLKL proteins levels were increased, while caspase-8 protein level was decreased in the hippocampus of Al-exposed groups. These results proved that AlCl3 induced hippocampal neural cells apoptosis and necroptosis. Combined with histopathology and correlation analysis, we deduced that hippocampal neural cells were more likely to undergo necroptosis at high doses (450 mg/kg) of AlCl3, while <150 mg/kg AlCl3 tended to induce apoptosis. Finally, AlCl3 increased the proteins level of IL-1β, IL-1RI, IL-1RAcP, JNK and p-JNK, indicating that AlCl3 activated IL-1β/JNK signaling pathway. However, the application of IL-1 receptor antagonist (IL-1Ra) inhibited the phosphorylation of JNK and the related genes expression of apoptosis and necroptosis caused by AlCl3. Thus, we concluded that AlCl3 induced hippocampal neural cells death and depression-like behavior in rats by activating IL-1β/JNK signaling pathway.

Abstract
Disrupted clearance of all-trans-retinal (atRAL), a component of the visual (retinoid) cycle in the retina, may cause photoreceptor atrophy in autosomal recessive Stargardt disease (STGD1) and dry age-related macular degeneration (AMD). However, the mechanisms underlying atRAL-induced photoreceptor loss remain elusive. Here, we report that atRAL activates c-Jun N-terminal kinase (JNK) signaling at least partially through reactive oxygen species production, which promoted mitochondria-mediated caspase- and DNA damage-dependent apoptosis in photoreceptor cells. Damage to mitochondria in atRAL-exposed photoreceptor cells resulted from JNK activation, leading to decreased expression of Bcl2 apoptosis regulator (Bcl2), increased Bcl2 antagonist/killer (Bak) levels, and cytochrome c (Cyt c) release into the cytosol. Cytosolic Cyt c specifically provoked caspase-9 and caspase-3 activation and thereby initiated apoptosis. Phosphorylation of JNK in atRAL-loaded photoreceptor cells induced the appearance of γH2AX, a sensitive marker for DNA damage, and was also associated with apoptosis onset. Suppression of JNK signaling protected photoreceptor cells against atRAL-induced apoptosis. Moreover, photoreceptor cells lacking Jnk1 and Jnk2 genes were more resistant to atRAL-associated cytotoxicity. The Abca4 -/- Rdh8 -/- mouse model displays defects in atRAL clearance that are characteristic of STGD1 and dry AMD. We found that JNK signaling was activated in the neural retina of light-exposed Abca4 -/- Rdh8 -/- mice. Of note, intraperitoneal administration of JNK-IN-8, which inhibits JNK signaling, effectively ameliorated photoreceptor degeneration and apoptosis in light-exposed Abca4 -/- Rdh8 -/- mice. We propose that pharmacological inhibition of JNK signaling may represent a therapeutic strategy for preventing photoreceptor loss in retinopathies arising from atRAL overload.

Abstract
STUDY DESIGN Xenograft osteosarcoma mouse model. OBJECTIVE We determined the effect of lycorine on osteosarcoma. SUMMARY OF BACKGROUND DATA Osteosarcoma is an aggressive malignant neoplasm, is most prevalent in teenagers and adults and current treatment approaches have reached a survival plateau and attempts to improve osteosarcoma prognosis have proven unsuccessful. Thus there is clear evidence that development of new agents with high efficacy and fewer side effects to provide better prognostic outcome is urgently needed. METHODS The toxicity, function and mechanism of lycorine (LY) on osteosarcoma were accessed in vitro by CCK-8 assay, flow cytometry, and western blotting and in vivo by the xenograft osteosarcoma mouse model. RESULTS In this study, we found that LY exhibited dose-dependent and time-dependent cytotoxic effects on human osteosarcoma cell-lines SJSA-1 and U2OS, inducing G1 phase cell cycle arrest and cellular death via apoptosis. Mechanistically, LY treatment elevated ROS generation that activates the p38 mitogen-activated protein kinases (MAPKs) and p53-dependent apoptotic program. Inhibition of ROS generation by NAC or p38 MAPK signaling by SB203580 attenuated the p53-mediated cell cycle arrest and apoptosis induced by LY. In vivo administration of LY markedly reduced tumor growth with little organ-related toxicity in a mouse xenograft model of osteosarcoma. CONCLUSION Collectively, our data suggests that LY exhibit therapeutic potential for the treatment of osteosarcoma. LEVEL OF EVIDENCE N/A.

Abstract
A novel series of shikonin-benzo[b]furan derivatives were designed and synthesized as tubulin polymerization inhibitors, and their biological activities were evaluated. Most compounds revealed the comparable anti-proliferation activities against the cancer cell lines to that of shikonin and simultaneously low cytotoxicity to non-cancer cells. Among them, compound 6c displayed powerful anti-cancer activity with the IC50 value of 0.18 μM against HT29 cells, which was significantly better than that of the reference drugs shikonin and CA-4. What's more, 6c could inhibit tubulin polymerization and compete with [3H] colchicine in binding to tubulin. Further biological studies depicted that 6c can induce cell apoptosis and cell mitochondria depolarize, regulate the expression of apoptosis related proteins in HT29 cells. Besides, 6c actuated the HT29 cell cycle arrest at G2/M phase, and influenced the expression of the cell-cycle related protein. Moreover, 6c displayed potent inhibition on cell migration and tube formation that contributes to the antiangiogenesis. These results prompt us to consider 6c as a potential tubulin polymerization inhibitor and is worthy for further study.

Abstract
Development of antifungal agents with novel mechanism and low toxicity are essential due to the prevalence of the infectious diseases caused by Candida albicans. The current study employed a new research method, which combined the ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry and gas chromatography-mass spectrometry, to investigate the intrinsic mechanism of Shikonin (SK) against C. albicans. The levels of 27 metabolites, which mainly involved in histone deacetylation, amino acid synthesis, lipid synthesis, nitrogen metabolism, tricarboxylic acid cycle, oxidative stress and glycolysis, were remarkably changed upon SK treatment. Specially, the down-regulation of nicotinamide (NAM) upon SK treatment indicated the suppression of the deacetylation of the histone H3 on lysine 56 residue (H3K56). Further experiment confirmed that the level of H3K56 acetylation (H3K56ac) was dramatically increased upon SK treatment which was mediated by HST3, the gene encoding the H3K56 deacetylase (Hst3p). Our results demonstrated that SK is the first natural compound reported to execute antifungal activity directly via boosting H3K56ac mediated by HST3. Importantly, this finding shed new light on the mechanisms to relieve the side effects or reverse the drug tolerance, as well as the development of agents for antifungal therapies.

Abstract
Cardamonin (CD), a naturally occurring chalcone isolated from large black cardamom, was previously reported to suppress the proliferation of breast cancer cells. However, its precise molecular anti-tumor mechanisms have not been well elucidated. In this study, we found that CD markedly inhibited the proliferation of MDA-MB 231 and MCF-7 breast cancer cells through the induction of G2/M arrest and apoptosis. Reactive oxygen species (ROS) plays a pivotal role in the inhibition of CD-induced cell proliferation. Treatment with N-acetyl-cysteine (NAC), an ROS scavenger, blocked CD-induced G2/M arrest and apoptosis in this study. Quenching of ROS by overexpression of catalase also blocked CD-induced cell cycle arrest and apoptosis. We showed that CD enhanced the expression and nuclear translocation of Forkhead box O3 (FOXO3a) via upstream c-Jun N-terminal kinase, inducing the expression of FOXO3a and its target genes, including p21, p27, and Bim. This process led to the reduction of cyclin D1 and enhancement of activated caspase-3 expression. The addition of NAC markedly reversed these effects, knockdown of FOXO3a using small interfering RNA also decreased CD-induced G2/M arrest and apoptosis. In vivo, CD efficiently suppressed the growth of MDA-MB 231 breast cancer xenograft tumors. Taken together, our data provide a molecular mechanistic rationale for CD-induced cell cycle arrest and apoptosis in breast cancer cells.

Abstract
Colorectal carcinoma (CRC) is the third most common malignant tumor pathology worldwide. Despite progress in surgical procedures and therapy options, CRC is still a considerable cause of cancer-related mortality. In this study, we tested the antitumor effects of shikonin in CRC and tried to identify its potential mechanism. The potential target, molecular mechanism as well as in vitro and in vivo antitumor effects of shikonin in CRC cells were determined by an integrative protocol including quantitative proteomics, RT-PCR, western blotting, RNA interference and overexpression, apoptosis and autophagy assays, etc. Galectin-1 was a potential target of shikonin from the iTRAQ-based proteomic analysis in shikonin-treated SW620 cell. The overexpression and RNA silencing of galectin-1 in two CRC cells suggested that the shikonin sensitivity was correlation to galectin-1 levels. The ROS accumulation induced by shikonin was important to the formation of galectin-1 dimers. Dimer galectin-1 was found to be associated with the activation of JNK and downstream apoptosis or autophagy. Moreover, through functional in vitro studies, we showed that differences in galectin-1 level affected tumor cell proliferation, migration, and invasion. In summary, shikonin induced CRC cells apoptosis and autophagy by targeting galectin-1 and JNK signaling pathway both in vitro and in vivo, which suggested a potential novel therapy target for CRC.

Dubey D, Srivastav AK, Singh J, Chopra D, Qureshi S, Kushwaha HN, Singh N, Ray RS. Photoexcited triclosan induced DNA damage and oxidative stress via p38 MAP kinase signaling involving type I radicals under sunlight/UVB exposure. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2019; 174:270-282. [PMID: 30844667 DOI: 10.1016/j.ecoenv.2019.02.065] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/11/2019] [Revised: 02/14/2019] [Accepted: 02/20/2019] [Indexed: 06/09/2023]
Abstract
Triclosan (TCS) is an antimicrobial preservative used in personal care products. Here, we have studied the phototoxicity, photogenotoxicity of TCS and its molecular mechanism involving p38 mitogen activated protein kinase (MAPK) pathway under UVB/sunlight exposure. We found that TCS showed photodegradation and photoproducts formation under UVB/sunlight. In silico study suggests that photosensitized TCS loses its preservative property due to the formation of its photoproducts. Photosensitized TCS induces significant O2•-, •OH generation and lipid peroxidation via type-I photochemical reaction mechanism under UVB/sunlight exposure. We performed intracellular study of TCS on human skin keratinocytes (HaCaT cell-line) under the ambient intensity of UVB (0.6 mW/cm2) and sunlight exposure. Significant intracellular ROS generation was observed through DCFH2-DA/DHE assays along with a significant reduction in cell viability through MTT and NRU assays in photosensitized TCS. Photosensitized TCS also induces endoplasmic reticulum (ER) stress as shown through ER-tracker/DAPI staining and Ca2+ release. It further induced cell cycle arrest through the sub-G1 phase augmentation and caused lysosomal/mitochondrial destabilization. Photogenotoxicity was shown through significant tail DNA, micronuclei and cyclobutane pyrimidine dimers (CPDs) formations. Cell signaling mechanism implicated upregulated expression of cleaved Caspase-3, Bax, phospho-p38, phospho-JNK and cytochrome C, thereby downregulated Bcl-2 expressions. Results advocate that TCS induces phototoxic effects via type I mediated photodynamic mechanism and activation of MAPK pathway. We conclude that photoexcited TCS may be deleterious to human health at the ambient environmental intensities of sunlight reaching at the earth's surface. Therefore, it may be replaced by alternative safe preservative.

Toxicol Lett 2019; 312:214-221. [PMID: 31128210 DOI: 10.1016/j.toxlet.2019.05.017] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Revised: 05/09/2019] [Accepted: 05/21/2019] [Indexed: 01/05/2023]
Abstract
Shikonin, a natural red colorant, is widely used for food garnishment and cosmetic ingredient in the world. Shikonin also possesses a variety of pharmacological actions, including anti-inflammation and anti-cancer activities. However, little is known about its effects on the UDP-glucuronosyltransferases (UGT) activity. Therefore, the aim of this study was to evaluate the effect of shikonin on the UGT1A1, UGT1A3, UGT1A6, UGT1A9 and UGT2B7 activities via the human and rat liver microsomal assay and cocktail approach. The results showed shikonin inhibited human and rat liver microsomal UGT activity only in a dose-dependent manner. The further enzyme kinetic studies demonstrated that shikonin was not only a competitive inhibitor of human UGT1A1, UGT1A9, and UGT2B7, but also presented competitive inhibition on rat UGT1A1 and AZTG reactions. In conclusion, shikonin as a reversible inhibitor of UGT enzyme has a high-risk potential to cause the possible toxicity, especially drug-drug or food-drug interactions.
