Abstract
Isoliquiritigenin (ISL) is a type of flavonoid, derived from the root of the legume plant Glycyrrhiza, that has multiple pharmacological properties. However, its role in cardiac remodeling induced by pressure overload has yet to be fully elucidated. Aortic banding (AB) surgery was used to establish a cardiac hypertrophy model in male C57BL/6 mice. Mice were randomly divided into four groups (n = 20 per group) as follows: Sham + vehicle, sham + ISL, AB + vehicle and AB + ISL. ISL was administered to the mice intragastrically for 1 week after the operation. To evaluate the role of ISL in mice challenged with AB, echocardiography, histological analysis and molecular biochemistry examinations were performed. ISL treatment decreased cardiac hypertrophy and improved cardiac dysfunction induced by pressure overload. In addition, ISL decreased the cross-sectional area of cardiomyocytes. Furthermore, ISL reversed the AB-mediated increase in phosphorylated (p-)mTOR and p-ERK protein levels and further increased the protein expression of p-AMP-activated protein kinase (AMPK)α in response to AB, whereas knockout of AMPKα abolished the protective effects of ISL. The present study suggested that ISL could suppress pressure overload-induced cardiac hypertrophy through the activation of AMPKα. Therefore, ISL may serve as a therapeutic target for cardiac remodeling.

Abstract
Acute myeloid leukemia is characterized by abnormal differentiation of hematopoietic stem cells, leading to the accumulation of immature myeloid cells. Differentiation therapy has been a successful treatment option for acute promyelocytic leukemia but suffers from adverse effects. Therefore, search for novel differentiation-inducing agents with minimal side effects is desirable. Securinine, a naturally-occurring alkaloid, induces differentiation in various leukemic cells and apoptosis in other types of cancers. However, the underlying molecular mechanism(s) remain elusive. Our study aimed to elucidate the possible molecular mechanism(s) and signaling events involved in securinine-induced differentiation of HL-60 cells. Securinine inhibited proliferation in a time- and dose-dependent manner and triggered differentiation. A higher CD14+ population indicated maturation toward monocytic lineage. Securinine caused cell cycle arrest at the G0/G1 phase and enhanced ROS generation. Quantitative gene expression analysis showed significant down-regulation of C/EBP-α, C/EBP-ε, GAΤΑ, and c-myc and up-regulation of the PU.1 gene. The expression of distinct protein kinases Lyn, Chk-2, Yes, FAK, c-Jun, and JNK were enhanced. Use of specific inhibitors of crucial intracellular signaling proteins indicated that JNK and ERK blockade resulted in a significant decline in differentiation. These data thus confirm that securinine induces differentiation through the activation of the JNK-ERK signaling pathway in HL-60 cells.

Abstract
Isoliquiritigenin (2',4',4-trihydroxychalcone, ISL), one of the most important bioactive compounds with a chalcone structure, is derived from licorice root. Licorice is commonly known as Glycyrrhiza, including Glycyrrhiza uralensis, Glycyrrhiza radix, and Glycyrrhiza glabra, which are generally available in common foods and Chinese herbal medicines based on a wide variety of biological functions and pharmacological effects, and its derivative (ISL) is utilized as a food additive and adjunct disease treatment. In this review, we summarized the progress over the last 10 years in the targeted pathways and molecular mechanisms of ISL that are involved in the regulation of the onset and progression of different types of cancers.

Isoliquiritigenin Induces Mitochondrial Dysfunction and Apoptosis by Inhibiting mitoNEET in a Reactive Oxygen Species-Dependent Manner in A375 Human Melanoma Cells. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:9817576. [PMID: 30805086 PMCID: PMC6360568 DOI: 10.1155/2019/9817576] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/05/2018] [Revised: 09/22/2018] [Accepted: 11/04/2018] [Indexed: 11/25/2022]
Abstract
The mitochondrial protein mitoNEET is a type of iron-sulfur protein localized to the outer membrane of mitochondria and is involved in a variety of human pathologies including cystic fibrosis, diabetes, muscle atrophy, and neurodegeneration. In the current study, we found that isoliquiritigenin (ISL), one of the components of the root of Glycyrrhiza glabra L., could decrease the expression of mitoNEET in A375 melanoma cells. We also demonstrated that mitoNEET could regulate the content of reactive oxygen species (ROS), by showing that the ISL-mediated increase in the cellular ROS content could be mitigated by the mitoNEET overexpression. We also confirmed the important role of ROS in ISL-treated A375 cells. The increased apoptosis rate and the decreased mitochondrial membrane potential were mitigated by the overexpression of mitoNEET in A375 cells. These findings indicated that ISL could decrease the expression of mitoNEET, which regulated ROS content and subsequently induced mitochondrial dysfunction and apoptosis in A375 cells. Our findings also highlight mitoNEET as a promising mitochondrial target for cancer therapy.

Abstract
Background Ovarian cancer is one of the most fatal gynecologic malignancies, with most patients diagnosed at the late stage due to insidious onset and lack of early onset specific symptoms. Previous studies have implied that isoliquiritigenin (ILQ) is a promising chemopreventive agent against oral cancer. Aim This study aimed to investigate effects of ILQ and elucidate the related mechanism. Materials and methods Ovarian cancer cell lines, SKOV3 and OVCAR3, were treated with various concentrations of ILQ to detect the dose-dependent effects of ILQ and select the suitable concentration. CCK8 assay and clone formation efficiency assays were used to detect viability and proliferation. The cell migration, invasion, and apoptosis were evaluated by wound healing assays, transwell, and flow cytometry assays. The expression of apoptosis-related proteins (Caspase-3, Caspase3-p17, Bcl-2, Bax, and Bim) and related-signaling pathway proteins were also detected by Western blot. Results It was observed that the treatment of ILQ inhibited the survival and proliferation of SKOV3 and OVCAR3 cells. ILQ treatment inhibited migration and invasion, and induced apoptosis in SKOV3 and OVCAR3 cells. Also, the ILQ treatment increased the Bax/Bcl-2 ratio in SKOV3 and OVCAR3 cells, suggesting that a mitochondrial apoptotic pathway was triggered. It was also observed that, after treated with ILQ, the phosphorylated form of Akt and mTOR decreased and the expression of GSK3β increased, while P70/S6K decreased. ILQ treatment also decreased the expression of Wnt3a and, therefore, caused the decrease of phosphorylated ERK. ILQ also suppressed the PI3K/Akt/mTOR pathway by reduced the expression level of p-Akt, p-mTOR, P70/S6K and Cyclin D1 in Ishikawa and ES-2 cells. Conclusion The data suggested that ILQ inhibited viability, proliferation, and invasion, and induced apoptosis of SKOV3 and OVCAR3 cells through the PI3K/Akt/mTOR pathway. Together, the data revealed that ILQ treatment may be used as a novel strategy for ovarian cancer therapy.

Abstract
Isoliquiritigenin (ISL), a member of the flavonoids, is known to have anti-tumor activity in vitro and in vivo. The effect of ISL on reprogramming in cancer cells, however, remains elusive. In this study, we investigated the effect of ISL on reprogramming in human melanoma A375 cells. ISL (15 μg/ml) significantly inhibited A375 cell proliferation, anchorage independent cell proliferation and G2/M cell cycle arrest after ISL exposure for 24 h. However, there were no significant changes in apoptosis rate. Terminal differentiation indicators (melanin content, melanogenesis mRNA expression, tyrosinase (TYR) activity) were all up-regulated by ISL treatment. In ISL-treated cells, glucose uptake, lactate levels and mRNA expression levels of GLUT1 and HK2 were significantly decreased, and accompanied by an increase in O2 consumption rate (OCR) and adenosine triphosphate (ATP) deficiency. Protein expression levels of mTORC2-AKT-GSK3β signaling pathway components (mTOR, p-mTOR, RICTOR, p-AKT, p-GSK3β) decreased significantly after ISL treatment. Co-treatment of ISL and the mTOR-specific inhibitor Ku-0063794 had a synergistic effect on the inhibition of proliferation, and increased melanin content and TYR activity. Glucose uptake and lactate levels decreased more significantly than treatment with ISL alone. These findings indicate that ISL induced reprogramming in A375 melanoma cells by activating mTORC2-AKT-GSK3β signaling.

Abstract
Isoliquiritigenin is a natural chalcone derived from Glycyrrhiza, which has been reported to have anti-tumor activity in recent years. Here, we investigate the anticancer efficacy and associated mechanisms of isoliquiritigenin in human prostate cancer PC-3 and 22RV1 cells. Isoliquiritigenin (25-50μM) inhibited cell proliferation, induced cell apoptosis, and caused G2/M cell cycle arrest in vitro. This agent also repressed the growth of PC-3 xenograft tumors in vivo with the results of hematoxylin/eosin staining and immunohistochemistry staining showing differences between isoliquiritigenin-treated groups and control group. Next, we used microarray transcriptional profiling to identify isoliquiritigenin-regulated genes on PC-3 prostate cancer cells. Multiple genes involved in cell cycle, DNA damage, and apoptosis signaling pathways were changed remarkably with the treatment of isoliquiritigenin. Molecular studies revealed that G2/M arrest was associated with a decrease in cyclin B1, cyclin-dependent kinase 1 (CDK1), and phosphorylated CDK1 (Thr14, Tyr15, and Thr161), whereas the expression of 14-3-3σ and growth arrest and DNA damage-inducible 45 alpha (GADD45A) was increased. The complexes of cyclin B1-CDK1 were also examined to show a decrease in the binding of CDK1 with cyclin B1. In addition, treatment with relatively high concentrations of isoliquiritigenin induced apoptosis, mainly associated with enhancing apoptosis regulator (Bax/Bcl-2) ratio. Collectively, these findings indicate that isoliquiritigenin modulates cyclin B1-CDK1 for G2/M arrest, together with an alteration of cell cycle regulators and apoptotic factors in human prostate cancer cells. However, we observed pleiotropic effects for isoliquiritigenin in microarray results, suggesting that other biological mechanisms also contribute to its efficacy, which could be of interest for future investigations.

Abstract
Despite the extensive work on pathological mechanisms and some recent advances in the treatment of different hematological malignancies, leukemia continues to present a significant challenge being frequently considered as incurable disease. Therefore, the development of novel therapeutic agents with high efficacy and low toxicity is urgently needed to improve the overall survival rate of patients. In this comprehensive review article, the current knowledge about the anticancer activities of flavonoids as plant secondary polyphenolic metabolites in the most commonly used human established leukemia cell lines (HL-60, NB4, KG1a, U937, THP-1, K562, Jurkat, CCRF- CEM, MOLT-3, and MOLT-4) is compiled, revealing clear anti-proliferative, pro-apoptotic, cell cycle arresting, and differentiation inducing effects for certain compounds. Considering the low toxicity of these substances in normal blood cells, the presented data show a great potential of flavonoids to be developed into novel anti-leukemia agents applicable also in the malignant cells resistant to the current conventional chemotherapeutic drugs.

Abstract
Recent findings have revealed that dysregulated miRNAs contribute significantly to autophagy and chemoresistance. Pharmacologically targeting autophagy-related miRNAs is a novel strategy to reverse drug resistance. Here, we report a novel function of isoliquiritigenin (ISL) as a natural inhibitor of autophagy-related miR-25 in killing drug-resistant breast cancer cells. ISL induced chemosensitization, cell cycle arrest and autophagy, but not apoptosis, in MCF-7/ADR cells. ISL also promoted the degradation of the ATP-binding cassette (ABC) protein ABCG2 primarily via the autophagy-lysosome pathway. More importantly, miRNA 3.0 array experiments identified miR-25 as the main target of ISL in triggering autophagy flux. A mechanistic study validated that miR-25 inhibition led to autophagic cell death by directly increasing ULK1 expression, an early regulator in the autophagy induction phase. miR-25 overexpression was demonstrated to block ISL-induced autophagy and chemosensitization. Subsequent in vivo experiments showed that ISL had chemosensitizing potency, as revealed by an increase in LC3-II staining, the downregulation of ABCG2, a reduction in miR-25 expression and the activation of the miR-25 target ULK1. Overall, our results not only indicate that ISL acts as a natural autophagy inducer to increase breast cancer chemosensitivity, but also reveal that miR-25 functions as a novel regulator of autophagy by targeting ULK1.

Abstract
AIMS The alteration of ROS level is frequently observed in the course of morphine addiction, and ROS is proverbially involved in this process. This study aims to explore the relationship among morphine addiction, reactive oxygen species (ROS) and expression of μ-opioid receptor (MOR) in differentiated SH-SY5Y cells. MAIN METHODS SH-SY5Y cells were induced to differentiation by treatment with retinoic acid (RA); the activity of lactate dehydrogenase (LDH) and the nitro blue tetrazolium (NBT) reduction were assessed by spectrophotometry. Intracellular reactive oxygen species (ROS) was measured with the 2,7-dichlorofluorescin diacetate (DCFH-DA) assay. Cellular cAMP was determined by using a competitive protein binding kit. The mRNA expression of μ-opioid receptor (MOR) was evaluated by qRT-PCR. KEY FINDINGS Morphine-induced ROS are generated in a concentration- and time-dependent manner and inhibited by naloxone. Exogenous oxidants increase the level of ROS and aggravate morphine addiction, while the exogenous antioxidants efficiently reverse these effects. Morphine decreases the mRNA level of MOR in a concentration-dependent manner. And the mRNA level of MOR is remarkably reduced in the presence of exogenous oxidants and effectively promoted by antioxidants. SIGNIFICANCE This study indicates that ROS can affect morphine addiction through involving MOR. Treatment with ROS scavenging can serve as a medical therapy for morphine addiction.

Abstract
AIMS The purpose of this study is to evaluate the anti-metastatic effects of alteronol on melanoma B16F10 and B16F1 cells in vitro and in vivo. MAIN METHODS Melanoma B16F1 and B16F10 cells were cultured in vitro. Cell proliferation was analyzed via 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. The cell migration and invasion were evaluated via wound healing and transwell chamber assays. The activity of matrix metalloproteinase 2 (MMP-2) in culture supernatants was assessed via gelatin zymography. The expression of MMP-2 and TIMP-2 were detected via enzyme-linked immunosorbent assay (ELISA) assay. The anti-metastatic ability in vivo was detected through experimental lung metastasis. KEY FINDINGS The data indicate that alteronol can inhibit the proliferation, invasion, and migration of B16F1 and B16F10 cells in vitro and in vivo, decrease the activity and expression of MMP-2, enhance the expression level of Tissue Inhibitor of Metalloproteinase-2 (TIMP-2), and inhibit the experimental lung metastasis of B16F1 and B16F10 cells. SIGNIFICANCE Although alteronol and taxol are obtained from the same source, these substances do not destroy the rare resource; the mechanisms of them on tumor growth inhibition are different. Conversely, alteronol treatment had lesser effects on normal cells revealing for a selective property and a strong competitive advantage.

Abstract
Isoliquiritigenin (ISL), a simple chalcone-type flavonoid, is derived from licorice compounds and is mainly present in foods, beverages, and tobacco. Reactive oxygen species (ROS) is a critical factor involved in modulating cardiac stress response signaling during ischemia and reperfusion. We hypothesize that ISL as a natural antioxidant may protect heart against ischemic injury via modulating cellular redox status and regulating cardioprotective signaling pathways. The fluorescent probe H2DCFDA was used to measure the level of intracellular ROS. The glucose uptake was determined by 2-deoxy-D-glucose-(3)H accumulation. The IonOptix System measured the contractile function of isolated cardiomyocytes. The results demonstrated that ISL treatment markedly ameliorated cardiomyocytes contractile dysfunction caused by hypoxia. ISL significantly stimulated cardioprotective signaling, AMP-activated protein kinase (AMPK), and extracellular signal-regulated kinase (ERK) signaling pathways. The ROS fluorescent probe H2DCFDA determination indicated that ISL significantly reduced cardiac ROS level during hypoxia/reoxygenation. Moreover, ISL reduced the mitochondrial potential (Δψ) of isolated mouse cardiomyocytes. Taken together, ISL as a natural antioxidant demonstrated the cardioprotection against ischemic injury that may attribute to the activation of AMPK and ERK signaling pathways and balance of cellular redox status.

Abstract
Redox balance plays an important role in the maintenance of cell growth and survival. Disturbance of this equilibrium can alter normal cellular processes. Excessive reactive oxygen species (ROS) are often found in cancer cells. However, cancer cells have an efficient antioxidant system to counteract the increased generation of ROS. This high antioxidant capacity also favors resistance to drugs and radiation. Here, we show that isoliquiritigenin (ISL), a natural antioxidant, effectively decreased ROS in HepG2 cells in a time-dependant manner at 0.5, 1, and 2 h of treatment. The decreased ROS caused redox imbalance and reductive stress. To adapt to this state, nuclear factor erythroid-2-related factor 2, which regulates the antioxidant enzyme system, was significantly decreased. Antioxidant enzymes reached their lowest level at 6 h after ISL treatment. Endogenous ROS were still being generated so after 6 h of ISL treatment, ROS were clearly higher than before ISL treatment, causing redox imbalance in the HepG2 cells which changed from reductive to oxidative stress. At this stage, cells were irradiated with X-rays. The excess ROS induced serious oxidative stress, resulting in radiosensitization. Therefore, we concluded that ISL induced oxidative stress by disturbing the redox status and ultimately enhancing the radiosensitivity of HepG2 cells.

Abstract
Chlorogenic acid (CA), is found in high abundance in the leaves of a number of plants and has antibacterial, antiphlogistic, antimutagenic, antioxidant and other biological activities. It reportedly possesses antitumor activity via the induction of apoptosis in chronic myelogenous leukemia (CML) cell lines, including U937 and K562 cells. However, the effects of CA on human acute promyelocytic leukemia (APL) HL‑60 cells remains unknown. In the current study, the ability of CA to cause G0/G1 cycle arrest and induce apoptosis in the treatment of human APL HL‑60 cells was investigated. Following 5 days treatment with 1, 5 and 10 µM CA, cell viability and the effects of CA on the growth of HL‑60 cells were investigated using a growth curve constructed using trypan blue staining. Induction of apoptosis and inhibition of cell proliferation were estimated using Wright's‑Giemsa staining, Hoechst 33342 and propidium iodide (PI) staining, DNA ladder analysis and flow cytometry, following 48 h cell treatment with various doses of CA. The results indicated that the growth of HL‑60 cells reached a plateau phase at 72 h and the proliferation inhibition rate of HL‑60 cells in CA‑treated groups was significantly higher compared with the control, in a time‑ and dose‑dependent manner. However, the level of apoptosis of HL‑60 cells treated with CA markedly increased and formed more apoptotic bodies compared with the cells with no drug treatment, according to the Wright's‑Giemsa staining, Hoechst 33342 and PI staining, respectively. Using DNA ladder analysis and flow cytometry it was shown that a significant characteristic DNA ladder was observed when treated with CA. CA was capable of arresting cell cycle at G0/G1 phase. Apoptosis of HL‑60 cells treated with CA for 48 h was promoted significantly in a dose‑dependent manner, as well as the inhibition of proliferation. The observations revealed that CA inhibits proliferation and induces preprophase apoptosis of HL‑60 cells. Thus, the concentration of 10 µM may be the optimal dose for treatment human acute promyelocytic leukemia.

Glycyrrhiza and Uncaria Hook contribute to protective effect of traditional Japanese medicine yokukansan against amyloid β oligomer-induced neuronal death. JOURNAL OF ETHNOPHARMACOLOGY 2013; 149:360-370. [PMID: 23838475 DOI: 10.1016/j.jep.2013.06.052] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/04/2013] [Revised: 05/24/2013] [Accepted: 06/30/2013] [Indexed: 06/02/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Yokukansan, a traditional Japanese (Kampo) medicine, composed of seven medicinal herbs has been traditionally used to treat neurosis, insomnia, and night crying and irritability in children. Recently, this medicine has been reported to improve the behavioral and psychological symptoms of dementia (BPSD) that often become problematic in patients with Alzheimer's disease (AD). AIM OF THE STUDY Amyloid β (Aβ) oligomers, which are extremely toxic to neurons, are involved in neurodegeneration in AD. In animals, yokukansan has been proven to improve memory impairments and BPSD-like behavior in transgenic mice overexpressing amyloid precursor protein and mice intracerebroventricularly injected with Aβ oligomers. These results suggest that yokukansan is potentially able to reduce the neurotoxicity of Aβ oligomers. Therefore, the present study aimed to explore the improving effects brought by yokukansan that consists of seven herbs for Aβ oligomer-induced neurotoxicity in vitro and to identify the candidate herbs in yokukansan's action. MATERIALS AND METHODS Primary cultured rat cortical neurons were used. Neurotoxicity induced by Aβ oligomers (3µM) and improving effects of yokukansan (300-1000 µg/mL) and its constituent herbs were evaluated in MTT assay, DNA fragmentation analysis, and electron microscopic analysis at 48h after treatment with Aβ oligomers and drugs. Moreover, changes in expression of genes related to endoplasmic reticulum (ER) stress and in caspase-3 activity that is the enzyme closely related to apoptosis were analyzed to investigate the underlying mechanisms. RESULTS Yokukansan ameliorated Aβ oligomer-induced neuronal damage in a dose-dependent manner in the MTT assay. This drug also suppressed DNA fragmentation caused by Aβ oligomers. Electron microscopic analysis suggested that yokukansan reduced karyopyknosis and the expansion of rough ER caused by Aβ oligomers. However, neither Aβ oligomers nor yokukansan affected the mRNA expression of any ER stress-related genes, including CHOP and GRP78. On the other hand, yokukansan dose-dependently suppressed Aβ oligomer-induced activation of caspase-3. Among the seven constituents of yokukansan, Glycyrrhiza and Uncaria Hook (60-200 µg/mL) suppressed Aβ oligomer-induced neuronal damage, DNA fragmentation, karyopyknosis, and caspase-3 activation to almost the same extent as yokukansan. CONCLUSIONS The present results suggest that yokukansan possesses an ameliorative effect against Aβ oligomer-induced neuronal apoptosis through the suppression of caspase-3 activation. Glycyrrhiza and Uncaria Hook may, at least in part, contribute to the neuroprotective effect of yokukansan. These mechanisms may underlie the improving effects of yokukansan on memory impairment and BPSD-like behaviors induced by Aβ oligomers.

Abstract
To evaluate the role of redox homeostasis in differentiation in human promyelocytic leukemia cells (HL-60) induced by isoliquiritigenin (ISL) through modulation of the nuclear erythroid-related factor 2/antioxidant responsive element (Nrf2/ARE) pathway. Morphological changes, cell surface markers CD11b/CD14, and nitroblue tetrazolium (NBT)-reducing ability were used to determine the differentiation of HL-60, and 2,7-dichlorofluorescein was used to detect the level of intracellular reactive oxygen species (ROS). Thiobarbituric acid test was utilised to determine the levels of malondialdehyde production in ISL-treated HL-60. The study determines and presents the redox state of the ratio of reduced/oxidised glutathione as a consequence of progression from differentiation in HL-60. Expression levels of the Nrf2/ARE downstream target genes were determined by quantitative polymerase chain reaction. Nicotinamide adenine dinucleotide phosphate-oxidase (NADPH oxidase) inhibitors, apocynin (APO), and diphenyleneiodonium (DPI) were used for the preliminary study to determine the potential downstream targets regulated by NADPH oxidase in ISL-induced HL-60 differentiation. The data showed a strong dose-response relationship between ISL exposure and the characteristics of HL-60 differentiation, namely, morphology changes, NBT reductive activities, and expression levels of surface antigens CD11b/CD14. Intercellular redox homeostasis changes toward oxidation during drug exposure are necessary to support ISL-induced differentiation. The unique expression levels of the Nrf2/ARE downstream target genes in the differentiation of HL-60 recorded a statistically significant and dose-dependent increase (P < 0.05), which were suppressed by NADPH oxidase inhibitor, APO, and DPI. ISL as a differentiation-inducing agent with mechanisms involved in the Nrf2/ARE pathway to modulate intercellular redox homeostasis, and thus, facilitate differentiation.

Abstract
The aim of this study was to evaluate the antitumour activities and genotoxic effects of isoliquiritigenin (ISL) combined with cyclophosphamide (CP) in vitro and in vivo. U14 cells were treated with either of ISL (5-25 μg/mL) or CP (0.25-1.25 mg/mL) alone or with combination of ISL (5-25 μg/mL) and CP (1.0 mg/mL) for 48 h. The proliferation inhibitory effect in vitro was evaluated by MTT and colony formation assays. KM mice bearing U14 mouse cervical cancer cells were used to estimate the antitumour activity in vivo. The genotoxic activity in bone marrow polychromatic erythrocytes was assayed by frequency of micronuclei. The DNA damage in peripheral white blood cells was assayed by single cell gel electrophoresis. The results showed that ISL enhanced antitumour activity of CP in vitro and in vivo, and decreased the micronucleus formation in polychromatic erythrocytes and DNA strand breaks in white blood cells in a dose-dependent way.

Abstract
Angiogenesis is crucial for cancer initiation, development and metastasis. Identifying natural botanicals targeting angiogenesis has been paid much attention for drug discovery in recent years, with the advantage of increased safety. Isoliquiritigenin (ISL) is a dietary chalcone-type flavonoid with various anti-cancer activities. However, little is known about the anti-angiogenic activity of isoliquiritigenin and its underlying mechanisms. Herein, we found that ISL significantly inhibited the VEGF-induced proliferation of human umbilical vein endothelial cells (HUVECs) at non-toxic concentration. A series of angiogenesis processes including tube formation, invasion and migration abilities of HUVECs were also interrupted by ISL in vitro. Furthermore, ISL suppressed sprout formation from VEGF-treated aortic rings in an ex-vivo model. Molecular mechanisms study demonstrated that ISL could significantly inhibit VEGF expression in breast cancer cells via promoting HIF-1α (Hypoxia inducible factor-1α) proteasome degradation and directly interacted with VEGFR-2 to block its kinase activity. In vivo studies further showed that ISL administration could inhibit breast cancer growth and neoangiogenesis accompanying with suppressed VEGF/VEGFR-2 signaling, elevated apoptosis ratio and little toxicity effects. Molecular docking simulation indicated that ISL could stably form hydrogen bonds and aromatic interactions within the ATP-binding region of VEGFR-2. Taken together, our study shed light on the potential application of ISL as a novel natural inhibitor for cancer angiogenesis via the VEGF/VEGFR-2 pathway. Future studies of ISL for chemoprevention or chemosensitization against breast cancer are thus warranted.

Abstract
Aspidin BB, an effective phloroglucinol derivative from Dryopteris fragrans (L.) Schott, has been previously reported to exert high biological activities. In this study, we analyzed the underlying mechanisms of aspidin BB on human ovarian cancer cell line, HO-8910. Aspidin BB significantly inhibited HO-8910 cell proliferation in a dose- and time-dependent manner. The IC50 values were 15.02, 25.79 and 68.81μM after 72, 48 and 24h treatment, respectively. Meanwhile, aspidin BB markedly induced apoptosis evidenced by characteristic apoptotic morphological changes, nuclear DNA fragmentation, annexin V-FITC/propidium iodide (PI) double staining and S peak. Western blot analysis showed that aspidin BB suppressed Bcl-2 expression and enhanced Bax expression to desintegrate the outer mitochondrial membrane, then caused cytochrome c release which led to the activation of effector caspase-3, and further cleaved the poly ADP-ribose polymerase (PARP) in the nucleus, finally induced cell apoptosis. Furthermore, aspidin BB provoked S phase arrest in HO-8910 cells with up-regulation of pRb, E2F1, CDK2, cyclin E and cyclin A proteins. Taken together, these findings support the conclusion that aspidin BB exhibits cytotoxicity towards human ovarian cancer HO-8910 cells through induction of apoptosis via mitochondrial pathway and arresting cell cycle progression in S phase.

Isoliquiritigenin-induced differentiation in mouse melanoma B16F0 cell line. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2012; 2012:534934. [PMID: 23304254 PMCID: PMC3529869 DOI: 10.1155/2012/534934] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/05/2012] [Revised: 11/03/2012] [Accepted: 11/08/2012] [Indexed: 12/27/2022]
Abstract
The chemotherapeutical treatment is very limited for malignant melanoma, a highly lethal disease occurs globally. Natural products derived from traditional Chinese medicine licorice are attractive in quest new treatments due to their anti-tumor activities. A new dietary flavonoid isoliquiritigenin (ISL) were thus investigated to indentify its anti-melanoma activities on mouse melanoma B16F0 cells in present study. Using biochemical and free radical biological experiments in vitro, we identified the pro-differentiated profiles of ISL and evaluated the role of reactive oxygen species (ROS) during B16F0 cell differentiation. The data showed a strong dose-response relationship between ISL exposure and the characteristics of B16F0 differentiation in terms of morphology changes and melanogenesis. The accumulated intercellular ROS during exposure are necessary to support ISL-induced differentiation, which was proven by additional redox modulators. It was confirmed further by the relative activities of enzymes and genes modulated melanogenesis in ISL-treatments with or without ROS modulators. The tumorigenicity of ISL-treated cells was limited significantly by using the colony formation assay in vitro and an animal model assay in vivo respectively. Our research demonstrated that isoliquiritigenin is a differentiation-inducing agent, and its mechanisms involve ROS accumulation facilitating melanogenesis.

NADPH oxidase-derived reactive oxygen species are involved in the HL-60 cell monocytic differentiation induced by isoliquiritigenin. Molecules 2012; 17:13424-38. [PMID: 23147401 PMCID: PMC6268504 DOI: 10.3390/molecules171113424] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2012] [Revised: 10/24/2012] [Accepted: 11/07/2012] [Indexed: 01/31/2023] Open
Abstract
The present study was undertaken to test the hypothesis that NADPH oxidase-derived reactive oxygen species (ROS) are involved in isoliquiritigenin (ISL)-induced monocytic differentiation in human acute promyelocytic leukemia HL-60 cells. Morphological changes, cell surface markers CD11b/CD14 and NBT-reducing ability were used to determine the differentiation of HL-60 cells, and 2,7-dichlorofluorescein (DCFH-DA) was used to detect the level of intracellular ROS. ISL-induced HL-60 cell differentiation was accompanied by an increase in the intracellular ROS levels. l-Buthionine-(S,R)-sulfoximine (BSO), N-acetyl-l-cysteine (NAC), superoxide dismutase (SOD) and 4-hydroxy-2,2,6,6-tetramethylpiperidinoxyl (Tempol) were used to interfere with ROS production. NADPH oxidase inhibitors, apocynin (APO) and diphenyleneiodonium (DPI) were used to study the role of NADPH oxidase in ISL-induced HL-60 cell differentiation. The ISL-induced HL-60 cell differentiation and intracellular ROS generation were enhanced by the oxidant BSO and inhibited by the antioxidants NAC, SOD, and tempol, and were also inhibited by the NADPH oxidase inhibitors APO and DPI. The protein and mRNA expression of the NADPH oxidase subunits gp91phox and p47phox were determined by Western blotting and RT-PCR, respectively. The levels of translation and transcription of the NADPH oxidase subunits gp91phox and p47phox increased markedly in a concentration-dependent manner. These findings suggest that NADPH oxidase plays a critical role in HL-60 cell differentiation induced by ISL and that NADPH oxidase-derived ROS is involved in the differentiation mechanism.

The critical role of redox homeostasis in shikonin-induced HL-60 cell differentiation via unique modulation of the Nrf2/ARE pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2012; 2012:781516.

Abstract
Among various cancer cell lines, the leukemia cell line HL-60 was most sensitive to Shikonin, with evidence showing both the prooxidative activities and proapoptotic effects of micromolar concentrations of Shikonin. However, the mechanism involved in the cytotoxicity of Shikonin in the submicromolar range has not been fully characterized. Using biochemical and free radical biological experiments in vitro, we identified the prodifferentiated profiles of Shikonin and evaluated the redox homeostasis during HL-60 differentiation. The data showed a strong dose-response relationship between Shikonin exposure and the characteristics of HL-60 differentiation in terms of morphology changes, nitroblue tetrazolium (NBT) reductive activity, and the expression level of surface antigens CD11b/CD14. During drug exposure, intercellular redox homeostasis changes towards oxidation are necessary to support Shikonin-induced differentiation, which was proven by additional enzymatic and non-enzymatic redox modulators. A statistically significant and dose-dependent increase (P < 0.05) was recorded with regard to the unique expression levels of the Nrf2/ARE downstream target genes in HL-60 cells undergoing late differentiation, which were restored with further antioxidants employed with the Shikonin treatment. Our research demonstrated that Shikonin is a differentiation-inducing agent, and its mechanisms involve the Nrf2/ARE pathway to modulate the intercellular redox homeostasis, thus facilitating differentiation.

Abstract
Licorice (Glycyrrhiza uralensis) is a medicinal herb containing various bioactive components implicated in antioxidative, anti-inflammatory, antiviral, and neuroprotective effects, but the effects of licorice against Parkinson's disease (PD)-related dopaminergic cell death have not been studied. In this study, we investigated the protective effects of isoliquiritigenin (ISL) isolated from Glycyrrhiza uralensis on 6-hydroxydopamine (6-OHDA)-induced neurotoxicity in a dopaminergic cell line, SN4741. ISL (1 µM) significantly attenuated 6-OHDA (50 µM)-induced reactive oxygen species (ROS) and nitric oxide (NO) generation and apoptotic cell death. ISL pretreatment effectively suppressed 6-OHDA-mediated upregulation of Bax, p-c-Jun N-terminal kinase (JNK), p-p38 mitogen-activated protein (MAP) kinase, cytochrome c release, and caspase 3 activation. In addition, ISL significantly attenuated 6-OHDA-induced Bcl-2, brain-derived neurotrophic factor (BDNF), and mitochondrial membrane potential (MMP) reduction. Pharmacological inhibitors of the phosphatidylinositol 3-kinase (PI3K)-Akt/protein kinase B (PKB) pathway reversed ISL-mediated neuroprotection against 6-OHDA toxicity in SN4741 cells. These results provide the first evidence that ISL can protect dopaminergic cells under oxidative stress conditions by regulating the apoptotic process.

Abstract
This study focuses on the relationship between the apoptosis induced by isoliquiritigenin (ISL) and the production of reactive oxygen species (ROS). Cell viability was evaluated using sulforhodamine B assay. The apoptotic rate was determined via flow cytometry. Intracellular ROS level was assessed using the 2,7-dichlorofluorescein probe assay. Poly-ADP-ribose polymerase (PARP) protein expression was examined using Western blot analysis. The results showed that ISL treatment inhibited cell proliferation by inducing apoptosis. The increased apoptotic rate and ROS production induced by ISL were inhibited by the co-treatment of ISL and free radical scavenger N-acetyl-cysteine (NAC), catalase (CAT), and 4,5-dihydroxyl-1,3-benzededisulfonic acid (Tiron). On the contrary, the increased apoptotic rate and the ROS production were compensated by the co-treatment of ISL and l-buthionine-(S,R)-sulfoximine (BSO). ISL treatment increased the degradation of PARP, which was counteracted by antioxidants (NAC or CAT), whereas the combination treatment of ISL and pro-oxidant (BSO) enhanced the PARP degradation induced by ISL. Our findings suggested that ISL treatment induced apoptosis by increasing intracellular ROS levels in HeLa cells.

Abstract
The aim of the present work was to develop a new method using synchronous fluorescence spectrometry (SFS) to determine the concentration of isoliquiritigenin (ISL) in mouse blood and tissues, and to investigate ISL's distribution among organs after an intraperitoneal (IP) dose of ISL. The synchronous fluorescence method was optimized with the sample pH, stability, metal ions, concentration of Al(3+), and surfactants. The proposed method was used to determine the ISL concentration in mouse blood, brain, heart, kidney, liver, spleen and lung after an IP injection of ISL. The optimal conditions for the determination of ISL using SFS were found to be: excitation and emission wavelengths of 469 and 557 nm, respectively; the use of 3% AlCl(3) as a fluorescence intensity enhancer; measuring samples within 1 h of collection, sample pH 7-8, isolation of samples from surfactants; and wavelength interval (Δλ) = 70 nm. After IP injection, the distribution of ISL in mouse organs was: liver > kidney > spleen > blood > lung > brain > heart. The blood concentration of ISL peaked at 60 min; concentrations of ISL in liver, kidney and spleen achieved maxima at 120 min. SFS provides a simple, but effective analytical method that will benefit the study of in vivo biological effects of ISL, including absorption, distribution, metabolism, and excretion.

Abstract
Oxidative stress plays an important role in tumorigenesis and metastasis. Salidroside, a phenylpropanoid glycoside isolated from Rhodiola rosea L., shows potent antioxidant property. Here we investigated the inhibitory effects of salidroside on tumor metastasis in human fibrosarcoma HT1080 cells in vitro. The results indicated that salidroside significantly reduced wound closure areas of HT1080 cells, inhibited HT1080 cells invasion into Matrigel-coated membranes, suppressed matrix metalloproteinases (MMP-2 and MMP-9) activity, and increased tissue inhibitor of metalloproteinase-2 (TIMP-2) expression in a dose-dependent manner in HT1080 cells. Salidroside treatment upregulated the E-cadherin expression, while downregulated the expression of β1-integrin. As an antioxidant, salidroside inhibited the intracellular reactive oxygen species (ROS) formation in a dose-dependent manner. The results also showed that salidroside could inhibit the activation of protein kinase C (PKC) and the phosphorylation of extracellular signal-regulated kinase 1 and 2 (ERK1/2) in a dose-dependent manner. In conclusion, these results suggest that salidroside inhibits tumor cells metastasis, which may due to its interfere in the intracellular excess ROS thereby down-regulated the ROS-PKC-ERK1/2 signaling pathway.

Abstract
Chalcones are absorbed in the daily diet and appear to be promising cancer chemopreventive agents. Chalcones represent an important group of the polyphenolic family, which includes a large number of naturally occurring molecules. This family possesses an interesting spectrum of biological activities, including antioxidative, antibacterial, anti-inflammatory, anticancer, cytotoxic, and immunosuppressive potential. Compounds of this family have been shown to interfere with each step of carcinogenesis, including initiation, promotion and progression. Moreover, numerous compounds from the family of dietary chalcones appear to show activity against cancer cells, suggesting that these molecules or their derivatives may be considered as potential anticancer drugs. This review will focus primarily on prominent members of the chalcone family with an 1,3-diphenyl-2-propenon core structure. Specifically, the inhibitory effects of these compounds on the different steps of carcinogenesis that reveal interesting chemopreventive and chemotherapeutic potential will be discussed.

Abstract
The development of drug resistance in cancer cells necessitates the identification of novel agents with improved activity towards cancer cells. In the present investigation, we compared the cytotoxicity of the chalcone flavonoide, isoliquiritigenin (ISL), with that of doxorubicin (DOX) and methotrexate (MTX) in five T cell acute lymphoblastic leukaemia (T-ALL) cell lines (Jurkat, J-Jhan, J16, HUT78 and Karpas 45). To gain insight into the molecular mechanisms which determine the response of T-ALL cells towards ISL, DOX and MTX, we applied array-based matrix comparative genomic hybridisation and microarray-based mRNA expression profiling and compared the genomic and transcriptomic profiles of the cell lines with their 50% inhibition (IC(50)) values for these three drugs. The IC(50) values for ISL did not correlate with those for DOX or MTX, indicating that ISL was still active in DOX- or MTX-unresponsive cell lines. Likewise, the genomic imbalances of chromosomal clones and mRNA expression profile significantly correlating with IC(50) values for ISL were different from thoses correlating with IC(50) values for DOX and MTX. In conclusion, ISL represents a cytotoxic natural product with activity towards T-ALL cell lines. There was no cross-resistance between ISL and DOX or MTX, and the genomic and transcriptomic profiles pointed to different molecular modes of action of ISL as compared to DOX and MTX, indicating that ISL may be a valuable adjunct for cancer therapy to treat otherwise drug-resistant tumours.
