PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 121:155096. [PMID: 37769554 DOI: 10.1016/j.phymed.2023.155096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 09/07/2023] [Accepted: 09/16/2023] [Indexed: 10/03/2023]
Abstract
BACKGROUND Polyphyllins are secondary metabolites that inhibit the growth of various tumours; however, clinical trials on their use are lacking. HYPOTHESIS/PURPOSE In this study, we aimed to evaluate the antitumour efficacy of polyphyllins in animal models. STUDY DESIGN Systematic review and meta-analysis. METHODS Electronic bibliographic databases including PubMed, Web of Science, China Science and Technology Journal Database, Wanfang Data, and China National Knowledge Infrastructure were searched for relevant articles. The Systematic Review Centre for Laboratory Animal Experimentation's Risk of Bias tool was used to assess methodological quality. RevMan V.5.4 (Cochrane) and Stata MP 17 software were used to perform a meta-analysis. RESULTS Thirty articles were analysed including 33 independent experiments and 452 animals in this paper. Overall, tumour volume (standardised mean difference [SMD]: -3.35; 95 % confidence interval [CI]: -4.27 to -2.43; p < 0.00001) and tumour weight (SMD: -3.79; 95% CI: -4.75 to -2.82; p < 0.00001) were reduced by polyphyllins, which showed a good cancer therapeutic effect; mouse weight (SMD: -0.22; 95% CI: -0.61 to -0.18; p = 0.28) was insignificantly different, which indicated that polyphyllins did not affect the growth of the mice within the test range. Moreover, the molecular mechanisms of the antitumour activity of polyphyllins were explained, including the P53, NF-kB, AMPK, and ERK signalling pathways. CONCLUSION Polyphyllins inhibit the growth of cancers within the experimental dose. However, due to heterogeneity of the results of the included studies, more studies are needed to support this conclusion.

Wang H, Han H, Xu Y, Yang Y. A simple and sensitive LC-MS/MS method for the determination of polyphyllin VII in rat plasma and its application to pharmacokinetic study. Biomed Chromatogr 2023; 37:e5597. [PMID: 36750761 DOI: 10.1002/bmc.5597] [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: 01/10/2023] [Revised: 02/01/2023] [Accepted: 02/04/2023] [Indexed: 02/09/2023]
Abstract
Polyphyllin VII is an isoprene saponin extracted from Rhizoma paridis, and it can effectively suppress tumor initiation, growth, and metastasis. In this study, we aim to develop and validate an LC-MS/MS method for the quantification of polyphyllin VII in rat plasma using digoxin as the internal standard (IS). The plasma samples were precipitated with methanol, and the samples were separated on an ACQUITY BEH C18 column (2.1 × 50 mm, 1.7 μm). The mobile phase consisted of 0.1% formic acid solution and acetonitrile. The detection was performed in the multiple reactions monitoring mode, with the precursor-to-product transitions of m/z 1075.4 > 883.3 for polyphyllin VII and m/z 779.4 > 649.6 for the IS. The method showed excellent linearity over the concentration range of 0.5-1000 ng/ml, with a correlation coefficient of 0.9996 (r = 0.9996). The lower limit of quantification was 0.5 ng/ml. The inter- and intra-day accuracy (relative error) ranged from -4.8 to 5.9%, and precision (relative standard deviation) was < 9.0%. The assay showed high extraction recovery, ranging from 90.6 to 95.6%. Polyphyllin VII was demonstrated to be stable under the storage conditions. The validated LC-MS/MS method was successfully applied to the pharmacokinetic study of polyphyllin VII in rats after oral, intraperitoneal, and intravenous administrations. The pharmacokinetic results indicated that polyphyllin VII showed low oral (5.86%) bioavailability and moderate (38.81%) intraperitoneal bioavailability.

Abstract
Background: Osteosarcoma (OS) is a common primary tumor with extensive heterogeneity. In this study, we used single-cell RNA sequencing (scRNA-seq) and network pharmacology to analyze effective targets for Osteosarcoma treatment. Methods: The cell heterogeneity of the Osteosarcoma single-cell dataset GSE162454 was analyzed using the Seurat package. The bulk-RNA transcriptome dataset GSE36001 was downloaded and analyzed using the CIBERSORT algorithm. The key targets for OS therapy were determined using Pearson's correlation analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed on key targets. The DeepDR algorithm was used to predict potential drugs for Osteosarcoma treatment. Molecular docking analysis was performed to verify the binding abilities of the predicted drugs and key targets. qRT-PCR assay was used to detect the expression of key targets in osteoblasts and OS cells. Results: A total of 21 cell clusters were obtained based on the GSE162454 dataset, which were labeled as eight cell types by marker gene tagging. Four cell types (B cells, cancer-associated fibroblasts (CAFs), endothelial cells, and plasmocytes) were identified in Osteosarcoma and normal tissues, based on differences in cell abundance. In total, 17 key targets were identified by Pearson's correlation analysis. GO and KEGG analysis showed that these 17 genes were associated with immune regulation pathways. Molecular docking analysis showed that RUNX2, OMD, and CD4 all bound well to vincristine, dexamethasone, and vinblastine. The expression of CD4, OMD, and JUN was decreased in Osteosarcoma cells compared with osteoblasts, whereas RUNX2 and COL9A3 expression was increased. Conclusion: We identified five key targets (CD4, RUNX2, OMD, COL9A3, and JUN) that are associated with Osteosarcoma progression. Vincristine, dexamethasone, and vinblastine may form a promising drug-target pair with RUNX2, OMD, and CD4 for Osteosarcoma treatment.

Abstract
CONTEXT Polyphyllin II (PPII) is a steroidal saponin isolated from Rhizoma Paridis. It exhibits significant antitumor activity such as anti-proliferation and pro-apoptosis in lung cancer. OBJECTIVE To explore whether PPII induce autophagy and the relationship between autophagy and apoptosis in non-small cell lung cancer (NSCLC) cells. MATERIALS AND METHODS The effects of PPII (0, 1, 5, and 10 μM) were elucidated by CCK8 assay, colony formation test, TUNEL staining, MDC method, and mRFP-GFP-LC3 lentivirus transfection in A549 and H1299 cells for 24 h. DMSO-treated cells were selected as control. The protein expression of autophagy (LC3-II, p62), apoptosis (Bcl-2, Bax, caspase-3) and p-mTOR was detected by Western blotting. We explored the relationship between autophagy and apoptosis by autophagy inhibitor CQ (10 μM) and 3-MA (5 mM). RESULTS PPII (0, 1, 5, and 10 μM) inhibited the proliferation and induced apoptosis. The IC50 values of A549 and H1299 cells were 8.26 ± 0.03 and 2.86 ± 0.83 μM. We found that PPII could induce autophagy. PPII promoted the formation of autophagosome, increased the expression of LC3-II/LC3-I (p < 0.05), while decreased p62 and p-mTOR (p < 0.05). Additionally, the co-treatment with autophagy inhibitors promoted the protein expression of c-caspase-3 and rate of Bax/Bcl-2 (p < 0.05), compared with PPII-only treatment group. Therefore, our results indicated that PPII-induced autophagy may be a mechanism to promote cell survival, although it can also induce apoptosis. CONCLUSIONS PPII-induced apoptosis exerts its anticancer activity by inhibiting autophagy, which will hopefully provide a prospective compound for NSCLC treatment.

Abstract
An effective method for separating and purifying critical saponins (polyphyllin II and polyphyllin VII) from a Paris polyphylla var. yunnanensis extract was developed in this study which was environmentally friendly and economical. Static adsorption kinetics, thermodynamics, and the dynamic adsorption-desorption of macroporous resins were investigated, and then the conditions of purification and separation were optimized by fitting with an adsorption thermodynamics equation and a kinetic equation. Effective NKA-9 resin from seven macroporous resins was screened out to separate and purify the two saponins. The static adsorption and dynamic adsorption were chemical and physical adsorption dual-processes on the NKA-9 resin. Under the optimum parameters, the contents of polyphyllin II and polyphyllin VII in the product were 17.3-fold and 28.6-fold those in plant extracts, respectively. The total yields of the two saponins were 93.16%. This research thus provides a theoretical foundation for the large-scale industrial production of the natural drugs polyphyllin II and polyphyllin VII.

Polyphyllin I Promotes Autophagic Cell Death and Apoptosis of Colon Cancer Cells via the ROS-Inhibited AKT/mTOR Pathway. Int J Mol Sci 2022; 23:ijms23169368.

Abstract
Colon cancer is a common malignant tumor of the digestive tract, and it is considered among the biggest killers. Scientific and reasonable treatments can effectively improve the survival rate of patients if performed in the early stages. Polyphyllin I (PPI), a pennogenyl saponin isolated from Paris polyphylla var. yunnanensis, has exhibited strong anti-cancer activities in previous studies. Here, we report that PPI exhibits a cytotoxic effect on colon cancer cells. PPI suppressed cell viability and induced autophagic cell death in SW480 cells after 12 and 24 h, with the IC50 values 4.9 ± 0.1 μmol/L and 3.5 ± 0.2 μmol/L, respectively. Furthermore, we found PPI induced time-concentration-dependent autophagy and apoptosis in SW480 cells. In addition, down-regulated AKT/mTOR activity was found in PPI-treated SW480 cells. Increased levels of ROS might link to autophagy and apoptosis because reducing the level of ROS by antioxidant N-acetylcysteine (NAC) treatment mitigated PPI-induced autophagy and apoptosis. Although we did not know the molecular mechanism of how PPI induced ROS production, this is the first study to show that PPI induces ROS production and down-regulates the AKT/mTOR pathway, which subsequently promotes the autophagic cell death and apoptosis of colon cancer cells. This present study reports PPI as a potential therapeutic agent for colon cancer and reveals its underlying mechanisms of action.

Abstract
Oral squamous cell carcinoma (OSCC) affects tens of thousands of people worldwide. Despite advances in cancer treatment, the 5-year survival rate of patients with late-stage OSCC is low at 50–60%. Therefore, the development of anti-OSCC therapy is necessary. We evaluated the effects of marine-derived triterpene stellettin B in human OC2 and SCC4 cells. Stellettin B dose-dependently decreased the viability of both cell lines, with a significant reduction in OC2 cells at ≥0.1 µM at 24 and 48 h, and in SCC4 cells at ≥1 µM at 24 and 48 h. Terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL)-positive cells were significantly observed at 20 µM of stellettin B at 48 h, with the overexpression of cleaved caspase3 and cleaved poly(ADP-ribose) polymerase (PARP). Moreover, mitochondrial respiratory functions were ablated by stellettin B. Autophagy-related LC3-II/LC3-I ratio and Beclin-1 proteins were increased, whereas p62 was decreased. At 20 µM at 48 h, the expression levels of the endoplasmic reticulum (ER) stress biomarkers calnexin and BiP/GRP78 were significantly increased and mitogen-activated protein kinase (MAPK) signaling pathways were activated. Further investigation using the autophagy inhibitor 3-methyladenine (3-MA) demonstrated that it alleviated stellettin B-induced cell death and autophagy. Overall, our findings show that stellettin B induces the ER stress, mitochondrial stress, apoptosis, and autophagy, causing cell death of OSCC cells.

Abstract
Paris polyphylla Sm. is an important medicinal plant used to treat a variety of diseases through traditional medicine systems such as Ayurveda, Tibetan traditional medicines, Chinese traditional medicines, and others around the world. The IUCN red list has designated it as "vulnerable" due to a decline in wild population by over-exploitation, habitat degradation, illegal collection for trade and traditional use. This review paper aims to summarize the bioactive secondary metabolites in Paris polyphylla. Paris saponins or steroidal saponins are the main bioactive chemical constituents from this plant that account for more than 80% of the total compounds. For instance, polyphyllin D, diosgenin, paris saponins I, II, VI, VII, and H are steroidal saponins having anticancer activity comparable to synthetic anticancer medicines. Antioxidant, anticancer, anti-leishmaniasis, antibacterial, antifungal, anthelmintic, antityrosinase, and antiviral effects of extracts and pure compounds were also demonstrated in vivo and in vitro. In conclusion, this review summarizes the bioactive components from the P. polyphylla which will be useful to researchers and scientists, and for the development of potential drugs.

Abstract
c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK) family members integrate signals that affect proliferation, differentiation, survival, and migration in a cell context- and cell type-specific way. JNK and p38 MAPK activities are found upregulated in nasopharyngeal carcinoma (NPC). Studies have shown that activation of JNK and p38 MAPK signaling can promote NPC oncogenesis by mechanisms within the cancer cells and interactions with the tumor microenvironment. They regulate multiple transcription activities and contribute to tumor-promoting processes, ranging from cell proliferation to apoptosis, inflammation, metastasis, and angiogenesis. Current literature suggests that JNK and p38 MAPK activation may exert pro-tumorigenic functions in NPC, though the underlying mechanisms are not well documented and have yet to be fully explored. Here, we aim to provide a narrative review of JNK and p38 MAPK pathways in human cancers with a primary focus on NPC. We also discuss the potential therapeutic agents that could be used to target JNK and p38 MAPK signaling in NPC, along with perspectives for future works. We aim to inspire future studies further delineating JNK and p38 MAPK signaling in NPC oncogenesis which might offer important insights for better strategies in diagnosis, prognosis, and treatment decision-making in NPC patients.

Loss of TACC1 variant25 inducing cell proliferation and suppressing autophagy in head and neck squamous carcinoma. Cell Death Discov 2021; 7:386. [PMID: 34897285 PMCID: PMC8665927 DOI: 10.1038/s41420-021-00777-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 11/14/2021] [Accepted: 11/30/2021] [Indexed: 12/03/2022] Open
Abstract
Transforming acidic coiled-coil containing protein1 (TACC1) is closely related to transcription, translation and centrosome dynamics. Dysregulation of TACC1 is associated with multiple malignancies. Alternative splicing (AS) of TACC1 produces multiple variants, which are of great significance in cancer biology. However, the expression and biological functions of TACC1 variants in head and neck squamous cell carcinoma (HNSCC) remain unclear. In this study, we found for the first time that TACC1 variants exhibited a characteristic expression pattern and that TACC1 variant25 (TACC1v25) was downregulated in HNSCC tissues and cell lines. Overexpression of TACC1v25 in Cal27 and Fadu cells significantly inhibited proliferation and promoted autophagy. Moreover, expression levels of nuclear pERK and p-mTOR were significantly decreased, while the expression of Beclin-1 and the LC3II/LC3I ratio were increased in TACC1v25-overexpressed Cal27 and Fadu cells. After the addition of AKT activator SC79 to TACC1v25-overexpressed Cal27 and Fadu cells, the autophagy levels were remarkably rescued. In conclusion, TACC1v25 inhibits HNSCC progression through the ERK and AKT/mTOR pathways by inhibiting proliferation and increasing autophagy. TACC1v25 might have potential use as a tumour suppressor in HNSCC.

ERK: A Double-Edged Sword in Cancer. ERK-Dependent Apoptosis as a Potential Therapeutic Strategy for Cancer. Cells 2021; 10:cells10102509.

Abstract
The RAF/MEK/ERK signaling pathway regulates diverse cellular processes as exemplified by cell proliferation, differentiation, motility, and survival. Activation of ERK1/2 generally promotes cell proliferation, and its deregulated activity is a hallmark of many cancers. Therefore, components and regulators of the ERK pathway are considered potential therapeutic targets for cancer, and inhibitors of this pathway, including some MEK and BRAF inhibitors, are already being used in the clinic. Notably, ERK1/2 kinases also have pro-apoptotic functions under certain conditions and enhanced ERK1/2 signaling can cause tumor cell death. Although the repertoire of the compounds which mediate ERK activation and apoptosis is expanding, and various anti-cancer compounds induce ERK activation while exerting their anti-proliferative effects, the mechanisms underlying ERK1/2-mediated cell death are still vague. Recent studies highlight the importance of dual-specificity phosphatases (DUSPs) in determining the pro- versus anti-apoptotic function of ERK in cancer. In this review, we will summarize the recent major findings in understanding the role of ERK in apoptosis, focusing on the major compounds mediating ERK-dependent apoptosis. Studies that further define the molecular targets of these compounds relevant to cell death will be essential to harnessing these compounds for developing effective cancer treatments.

Abstract
Magnolol is a natural compound extracted from Chinese herbal medicine and can induce apoptosis in numerous types of cancer cells. However, the molecular mechanisms of magnolol in oral cancer are still unclear. In this study, we investigated the anti-cancer effects and underlying mechanisms of magnolol in human oral cancer cell lines. Our results exhibited that magnolol inhibited the cell proliferation via inducing the sub-G1 phase and cell apoptosis of HSC-3 and SCC-9 cells. The human apoptosis array and Western blot assay showed that magnolol increased the expression of cleaved caspase-3 proteins and heme oxygenase-1 (HO-1). Moreover, we proved that magnolol induces apoptosis in oral cancer cell lines via the c-Jun N-terminal kinase (JNK)1/2 and p38 pathways. Overall, the current study supports the role for magnolol as a therapeutic approach for oral cancer through JNK1/2- and p38-mediated caspase activation.

Abstract
BACKGROUND AND OBJECTIVES Paris polyphylla (P. polyphylla) is a herb widely used in traditional Chinese medicine to treat various diseases. This study used ultrahigh-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) to study the pharmacokinetics and tissue distributions of nine steroidal saponins from P. polyphylla. METHODS P. polyphylla extract was administered to rats intravenously (i.v.) and orally (p.o.). The concentrations of the nine main bioactive components of the extract were determined in plasma and tissue samples using UPLC-MS/MS. The nine saponin compounds were also incubated in an anaerobic environment with intestinal flora suspension solution to investigate hydrolysis by intestinal flora. RESULTS After oral administration of the P. polyphylla extract, polyphyllin VII was found to have the highest maximum concentration (Cmax, 17.0 ± 2.24 µg/L) of all nine components, followed by the Cmax values of dioscin (16.17 ± 0.64 µg/L) and polyphyllin H (11.75 ± 1.28 µg/L), while the Cmax values of polyphyllin I, polyphyllin II, progenin III, polyphyllin IV, gracillin, and polyphyllin were less than 10 µg/L. The bioavailabilities of all nine components were less than 1%. All the compounds were hydrolyzed by intestinal flora and were predominantly distributed in the liver and lungs. CONCLUSIONS The nine compounds presented different pharmacokinetic parameter values, and multiple administrations did not accumulate in the body. The bioavailabilities of the compounds were low, partly because of hydrolysis by intestinal flora. The nine compounds were mainly distributed in the liver and lungs, which may be target organs.

Abstract
Cancer is the second leading cause of mortality worldwide. Conventional therapies, including surgery, radiation, and chemotherapy, have limited success because of secondary resistance. Therefore, safe, non-resistant, less toxic, and convenient drugs are urgently required. Natural products (NPs), primarily sourced from medicinal plants, are ideal for cancer treatment because of their low toxicity and high success. NPs cure cancer by regulating different pathways, such as PI3K/AKT/mTOR, ER stress, JNK, Wnt, STAT3, MAPKs, NF-kB, MEK-ERK, inflammation, oxidative stress, apoptosis, autophagy, mitophagy, and necroptosis. Among the NPs, steroid saponins, including polyphyllins (I, II, D, VI, and VII), have potent pharmacological, analgesic, and anticancer activities for the induction of cytotoxicity. Recent research has demonstrated that polyphyllins (PPs) possess potent effects against different cancers through apoptosis, autophagy, inflammation, and necroptosis. This review summarizes the available studies on PPs against cancer to provide a basis for future research.

Abstract
Dehydrocrenatidine, a β-carboline alkaloid isolated from Picrasma quassioides, has been demonstrated to exert analgesic effects and play essential roles in janus kinase inhibition and exert analgesic effects through the suppression of neuronal excitability. Alkaloids such as paclitaxel and vincristine had been well explored to be chemotherapeutic agents. However, the anticancer effects of dehydrocrenatidine remain unclear. In the present study, we found that dehydrocrenatidine induced apoptosis in human oral cancer cells through both extrinsic and intrinsic pathways involving proteins such as caspase-3, caspase-8, caspase-9, poly (adenosine diphosphate-ribose) polymerase, and members of the Bcl-2 family. Cotreatment with dehydrocrenatidine and mitogen-activated protein kinase (MAPK) inhibitors indicated that dehydrocrenatidine induced apoptosis through the activation of extracellular signal-regulated kinases (ERK) and c-Jun N-terminal kinases (JNK). The findings provide insight into the potential of dehydrocrenatidine for a new perspective on molecular regulation.

Abstract
Polyphyllin II (PII) and polyphyllin VII (PVII) are the main active ingredients in Paris Polyphylla with an excellent antitumor effect in vitro and in vivo. In this study, a rapid and precise LC-MS/MS method was developed and validated for the separation and simultaneous determination of PII and PVII in rat plasma, tissues, feces and urine using ginsenoside Rg3 as the internal standard. Positive linearity ranged from 1 to 1,000 ng/ml in samples. At the same time, intra- and inter-day precisions were in range of 1.8-12.0%. The accuracy ranged from 95.9 to 100.8%. Mean extraction recoveries of PII and PVII ranged from 86.6 to 96.4%. The analytical method has been successfully applied to the pharmacokinetic studies of PII and PVII in rats after their i.v. administration. After entering systemic circulation, PII and PVII were rapidly distributed in organs, mainly including liver, lung and spleen. Their elimination rate was slow. All of these data provided a theoretical basis for the application of PII and PVII in the treatment of liver- and lung-related diseases.

Abstract
Autophagy is a ubiquitous mechanism for maintaining cellular homeostasis through the degradation of long-lived proteins, insoluble protein aggregates, and superfluous or damaged organelles. Dysfunctional autophagy is observed in a variety of human diseases. With advanced research into the role that autophagy plays in physiological and pathological conditions, targeting autophagy is becoming a novel tactic for disease management. Saponins are naturally occurring glycosides containing triterpenoids or steroidal sapogenins as aglycones, and some saponins are reported to modulate autophagy. Research suggests that saponins may have therapeutic and preventive efficacy against many autophagy-related diseases. Therefore, this review comprehensively summarizes and discusses the reported saponins that exhibit autophagy regulating activities. In addition, the relevant signaling pathways that the mechanisms involved in regulating autophagy and the targeted diseases were also discussed. By regulating autophagy and related pathways, saponins exhibit bioactivities against cancer, neurodegenerative diseases, atherosclerosis and other cardiac diseases, kidney diseases, liver diseases, acute pancreatitis, and osteoporosis. This review provides an overview of the autophagy-regulating activity of saponins, the underlying mechanisms and potential applications for managing various diseases.

Abstract
Cancer is the leading cause of mortality in the world. The major therapies for cancer treatment are chemotherapy, surgery, and radiation therapy. All these therapies expensive, toxic and show resistance. The plant-derived compounds are considered safe, cost-effective and target cancer through different pathways. In these pathways include oxidative stress, mitochondrial dependent and independent, STAT3, NF-kB, MAPKs, cell cycle, and autophagy pathways. One of the new plants derived compounds is Polyphyllin VII (PPVII), which target cancer through different molecular mechanisms. In literature, there is a review gap of studies on PPVII; therefore in the current review, we summarized the available studies on PPVII to provide a base for future research.

Abstract
Colorectal cancer (CRC) is one of the most common types of human cancer. However, there is still an urgent need to identify novel treatment strategies for CRC. The present study aimed to validate the potential antitumor effects of polyphyllin VII in CRC. The present study revealed that polyphyllin VII could significantly inhibit CRC proliferation and induce cell cycle arrest and apoptosis. Moreover, the anti-metastatic effect of polyphyllin VII in CRC cells was implicated. Microarray analysis identified that polyphyllin VII could affect multiple protein coding genes and non-coding RNAs. Bioinformatics analysis revealed that polyphyllin VII regulated multiple pathways in CRC, including ‘ER to Golgi vesicle-mediated transport’, ‘response to cAMP’, ‘Ras protein signal transduction’, ‘metabolic pathways’, ‘MAPK signaling pathway’ and ‘cell cycle’. Protein-Protein Interaction network analysis identified a series of key polyphyllin VII-regulating genes in CRC, including ribonucleoside-diphosphate reductase subunit M2, structural maintenance of chromosomes protein 4 and DNA replication licensing factor MCM4. Finally, the present results demonstrated that these key polyphyllin VII-regulating genes were dysregulated in CRC. Taken together, these results indicated that polyphyllin VII could be a novel antitumor drug for the treatment of CRC.

Abstract
Osteosarcoma (OS) is the most common type of primary bone cancer. Even with advances in early diagnosis and aggressive treatment, the overall prognosis for OS remains to be further elevated. Lycorine was an isoquinoline alkaloid mainly existed in the bulb of lyco salvia miltiorrhiza and was shown to inhibit several types of cancer. In the present study, we investigated the anti-OS activity of lycorine and the possible underlying mechanism. We found that lycorine inhibited cell proliferation of human OS cells while had lower cytotoxcity against normal cells, and triggered cell cycle arrest at the G1/S transition. Moreover, we validated that lycorine promoted apoptosis via death receptor pathway and mitochondrial pathway, suppressed migration and invasion by reversing epithelial mesenchymal transition (EMT) and suppressing the degradation of extracellular matrix (ECM) in vitro. In addition, orthotopic implantation model of 143B OS cells further confirmed that lycorine suppressed OS growth and lung metastasis in vivo. Mechanically, lycorine reduced the protein level of β-catenin and its' downstream molecule c-Myc. Furthermore, lycorine also decreased the phosphorylation of ERK1/2 and AKT. Together, our results reveal that lycorine may inhibit tumor growth of OS cells possibly through suppressing Wnt/β-catenin, ERK1/2 and PI3K/AKT signaling pathway.

[PMID: 33279335 DOI: 10.1016/j.burns.2020.03.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Revised: 03/02/2020] [Accepted: 03/20/2020] [Indexed: 10/24/2022]
Abstract
Hypertrophic scar (HS) is a pathological scar that often occurs in burn patients. Its histology is characterized by the excessive proliferation of fibroblasts (FB) and excessive accumulation of extracellular matrix (ECM). Inhibition of proliferation and activation of FB is essential for the treatment of HS. The crude extracts of traditional Chinese medicines have beneficial therapeutic effects on HS besides possessing fewer side effects and being easily available. Polyphyllin VII (PP7) is an isoprene saponin isolated from Rhizoma paridis. It has a pro-apoptotic effect on cancer cells. In the present study, we demonstrate that PP7 exerts a significant inhibitory effect on hypertrophic scar fibroblasts (HSFs) in vitro. We also demonstrate that PP7 considerably induces the apoptosis of HSFs and inhibits their activity. Our data show that the PP7-induced HSFs cell apoptosis was mainly due to the enhanced expression of apoptotic genes (Bax, Caspase-3, Caspase-9) and decreased expression of Bcl-2. Moreover, PP7 treatment also enhances the expression of JNK, but that of extracellular protein kinases (ERK) was reduced, and induces apoptosis through ERK/JNK pathways. Thus, PP7 can be used as a drug to prevent the formation of HS.

[PMID: 31982774 PMCID: PMC6994412 DOI: 10.1016/j.omtn.2019.12.022] [Citation(s) in RCA: 44] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 11/27/2019] [Accepted: 12/19/2019] [Indexed: 12/19/2022]
Abstract
Multidrug resistance (MDR) is the resistance of cells toward various drugs commonly used in tumor treatment. The mechanism of drug resistance in oral cancer is not completely understood. Melatonin is an endogenously produced molecule involved in active biological mechanisms including antiproliferation, oncogene expression modulation, antitumor invasion and migration, and anti-inflammatory, antioxidant, and antiangiogenic effects. Despite these functions, the effects of melatonin on vincristine (VCR)-resistant human oral cancer cells remain largely unknown. This study analyzed the role of melatonin in VCR-resistant human oral cancer cells along with the underlying mechanism. We determined that melatonin induced the apoptosis and autophagy of VCR-resistant oral cancer cells; these actions were mediated by AKT, p38, and c-Jun N-terminal kinase (JNK). Melatonin inhibited ATP-binding cassette B1 (ABCB1) and ABCB4 expression in vitro and in vivo. Melatonin reduced the drug resistance and promoted the apoptosis of VCR-resistant oral cancer cells through the upregulation of microRNA-892a (miR-892a) and miR-34b-5p expressions. The expression of miR-892a and miR-34b-5p was related to melatonin-induced apoptosis, but not autophagy. Therefore, melatonin is a potential novel chemotherapeutic agent for VCR-resistant human oral cancer cell lines.

Abstract
Polyphyllin VII is an active compound isolated from Paris polyphylla, which is termed Chonglou in China. The present study was designed to investigate the underlying mechanisms of the antitumor effect of Polyphyllin VII in lung cancer cells. The cytotoxic effect of Polyphyllin VII in human lung cancer A549 cells was analyzed; the results revealed an IC50 value of 0.41±0.10 µM at 24 h. The associated mechanisms were investigated by phase-contrast microscopy, fluorescence microscopy, flow cytometry and western blot analysis. Exposure of A549 cells to Polyphyllin VII resulted in apoptosis. Pyrrolidine dithiocarbamate (PDTC), an inhibitor of NF-κB, and wortmannin, an inhibitor of PI3K, both decreased the proportion of viable A549 cells in the presence of Polyphyllin VII. The ratio of apoptotic cells increased in the presence of wortmannin and PDTC. Western blot analysis revealed that PI3K, phosphorylated (p)-PI3K, Akt, p-Akt, NF-κB and p-NF-κB were downregulated following treatment with Polyphyllin VII. Increased caspase-3 activity, increased poly-(ADP-ribose) polymerase cleavage and a downregulation of inhibitor of caspase-activated DNase were observed following treatment with Polyphyllin VII, and these effects were enhanced by either wortmannin or PDTC. The present results revealed that Polyphyllin VII was able to induce apoptotic cell death in A549 human lung cancer cells via inhibition of the PI3K/Akt and NF-κB pathways.

Abstract
To find the effect of Paris saponin VII (PS VII)-mediated PI3K/AKT/MAPK signaling pathway on the sensitivity of ADR-resistant HepG2 cell (HepG2/ADR) cells to ADR. The proliferation inhibitory rates were detected by using MTT assay. Flow cytometry was employed to examine the intracellular accumulation of ADR. The expressions of drug-resistant genes (P-gp, MRP and BCRP) were detected by qRT-PCR, cell apoptosis by Annexin-V-FITC/PI staining, and the expressions of drug-resistance-related proteins, apoptosis-related proteins, and PI3K/AKT/MAPK pathway-related proteins were determined by Western blotting. HepG2/ADR and HepG2 cells treated with PS VII (0.88, 1.32, 1.98, and 2.97 μM) for 48 hours showed increased proliferation inhibitory rate in a dose-dependent manner. HepG2/ADR cells treated PS VII (0.88, 1.32, 1.98 μM) for 48 hours showed decreased IC50 of ADR. Compared with HepG2/ADR cells treated with ADR (5 nM), those treated with PS VII (≤1.98 μM) and ADR (5 nM) showed enhanced ADR accumulation, decreased drug-resistant gene expressions, increased cell apoptosis with unregulated Bax and cleaved caspase-3 and downregulated Bcl-2, as well as the inhibition of PI3K/AKT/MAPK pathway. Moreover, the combination of ADR (5 nM), PS VII (1.98 μM), and LY294002 (PI3K/AKT inhibitor, 20 μM)/SB203580 (P38 inhibitor, 20 μM) for 48 hours could further decreased the HepG2/ADR cell viability, but induced cell apoptosis, accompanying with the decreased expressions of drug-resistant genes. PS VII could downregulate the expressions of drug-resistance genes, increase intracellular accumulation of ADR, promote cell apoptosis, and enhance the sensitivity of HepG2/ADR cells to ADR via PI3K/AKT/MAPK.

Abstract
The 1,4-naphthoquinones and their derivatives have garnered great interest due to their antitumor pharmacological properties in various cancers; however, their clinical application is limited by side effects. In this study, to reduce side effects and improve therapeutic efficacy, a novel 1,4-naphthoquinone derivative-2-(4-methoxyphenylthio)-5,8-dimethoxy-1,4-naphthoquinone (MPTDMNQ) was synthesized. We investigated the effects and underlying mechanisms of MPTDMNQ on cell viability, apoptosis, and reactive oxygen species (ROS) generation in human gastric cancer cells. Our results showed that MPTDMNQ decreased cell viability in nine human gastric cancer cell lines. MPTDMNQ significantly induced apoptosis accompanied by the accumulation of ROS in GC cells. However, pre-treatment with the ROS scavenger N-acetyl-L-cysteine (NAC) attenuated the MPTDMNQ-induced apoptosis. Moreover, MPTDMNQ decreased the phosphorylation levels of extracellular signal-regulated kinase (ERK) and signal transducer and activator of transcription 3 (STAT3); and increased the phosphorylation levels of c-Jun N-terminal kinase (JNK) and p38 kinase. However, phosphorylation was inhibited by NAC and a mitogen-activated protein kinase (MAPK) inhibitor. These findings showed that MPTDMNQ induced AGS cell apoptosis via ROS-mediated MAPK and STAT3 signaling pathways. Thus, MPTDMNQ may be a promising candidate for treating gastric cancer.

Abstract
Recently, the incidence of hepatocellular carcinoma has increased worldwide. Cembranoid-type diterpenes (CBDs) from tobacco exhibit good antimicrobial, antitumor, and neuroprotective activities. Therefore, in this study, we isolated CBDs from Nicotiana tabacum L. and evaluated their antitumor activity against hepatoma cell lines. Particularly, the anti-tumor activity of α-2,7,11-cyprotermine-4,6-diol (α-CBD) was investigated against HepG2, SMMC-7721, and HL-7702 cells. The MTT assay revealed that α-CBD reduced the formation of cell clones and inhibited the proliferation of hepatocellular carcinoma cells. Morphological observations showed that α-CBD altered cell morphology and membrane permeability before inducing apoptosis. To further explore the antitumor mechanism of α-CBD, flow cytometry and transcriptome analysis were performed using HepG2 cells. The results showed that the number of HepG2 cells increased from 10.4% to 29.8%, indicating that α-CBD inhibits the proliferation of hepatocellular carcinoma cells in the S phase. The gene expression analysis of HepG2 cells treated with α-CBD showed 3068 genes with altered expression, among which 1289 were upregulated and 1779 were downregulated. Apoptosis induced by these differentially expressed genes might be mediated by the p53-PUMA, PI3K-Akt, and IL-1-NF-κB-IAP pathways. Comprehensively, our study shows that α-CBD isolated from N. tabacum L. can be potentially used as a natural antitumor agent.

Abstract
Coronarin D, a diterpene derived from the rhizomes of Hedychium coronarium, has been used to treat inflammatory diseases. Coronarin D can exert strong anticancer effects through cell growth prevention and cell cycle arrest in many cancer cells. In this study, we investigated the molecular mechanism through which coronarin D suppresses cell proliferation and triggers cell death in human hepatocellular carcinoma (HCC) cells. Treatment of Huh7 and Sk-hep-1 cells with coronarin D resulted in a significantly increased loss of mitochondrial membrane potential, leading to the cleavage and activation of caspase-9, caspase-8, and caspase-3 and changes in Bax, Bcl-2, and Bcl-xL protein levels. Coronarin D significantly induced autophagy by increasing the expression of Beclin-1 and LC3-II and reducing the expression of p62. Moreover, Huh7 and Sk-hep-1 cells exposed to coronarin D had decreased expression of phosphorylated AKT, p38, and ERK and increased expression of phosphorylated JNK. Exposure of cells to the JNK-specific inhibitor SP600125 attenuated the apoptotic effects of coronarin D. Taken together, this is the first study to report that coronarin D may effectively inhibit cell growth through apoptosis. We have provided evidence indicating that coronarin D induces cell death through the upregulation of JNK mitogen-activated protein kinases in human HCC cells.

Abstract
BACKGROUND The cancerous inhibitor of protein phosphatase 2A (CIP2A) is an oncoprotein which involves in the progression of several human malignancies. Development of cisplatin (DDP) resistance is the obstacle to an effective control of gastric cancer (GC) clinically. OBJECTIVE We thus assessed whether CIP2A expression is associated with sensitivity of GC to DDP. METHODS Real-time quantitative PCR, immunohistochemical analysis, or western blotting was performed to detect CIP2A expression in GC patients' tissues. SGC7901/DDP cells were transfected with CIP2A siRNA. MTT assay was used to determine the DDP-sensitivity of cells. Flow cytometry was used to measure cell apoptosis. RESULTS CIP2A has higher expression in DDP-resistant GC patients. DDP-resistant GC patients with high CIP2A expression presented with poorer overall survival rates than those with low CIP2A expression. CIP2A knockdown in DDP-resistant GC cells resulted in attenuated proliferative abilities and increased apoptosis level. CIP2A depletion sensitizes DDP-resistant cells to DDP and CIP2A overexpression antagonizes DDP-sensitive cells to DDP. CIP2A influences the expression of multidrug resistance-related proteins in GC cells. CONCLUSIONS Our results suggested that CIP2A oncoprotein plays an important role in DDP resistance of GC and could serve as a novel therapeutic target for the treatment of GC patients with DDP resistance.

Abstract
Viral myocarditis is a cardiovascular disease that seriously affects human health. Its mechanism is not clear. Coxsackievirus B3 (CVB3) is a member of the picornavirus family and is the leading cause of viral myocarditis. Our group tested the genes in a mouse model of CVB3 virus infection and confirmed that the NADPH oxidase gene had a high expression trend in the acute phase of infection. Whether Nox4, the homologue of NADPH oxidase, participates in the process of viral myocarditis has not been reported. In this study, we found increased expression of Nox4 in viral myocarditis in vivo and in vitro. DPI is a non-specific inhibitor of Nox4 that improved CVB3-induced myocarditis after injection in vivo. DPI also inhibited intracellular ROS release and apoptosis in vitro. Our data indicated that Nox4-dependent ROS production was involved in CVB3-induced myocardial apoptosis.

Abstract
Polyphyllin I (PPI) is a natural compound extracted from the rhizomes of Paris polyphylla and has been used to treat fevers and headaches in China. In the present study, the antitumor activity of PPI in prostate cancer (PC) cells was evaluated. At low doses, PPI decreased proliferation, invasion and epithelial-mesenchymal transition (EMT) in PC cells. PPI decreased the expression of matrix metalloproteinase 7 (MMP7), an enzyme that is critical for tumor metastasis. PPI also decreased the expression of Snail and vimentin, which are EMT-associated factors. Additionally, PPI suppressed AP-1 transcriptional activity and AP-1 binding to the MMP7 and vimentin promoters. The results demonstrated that PPI downregulated the phosphorylation of extracellular signaling‑related kinase (ERK), which is upstream modulator of AP-1. The results of the present study demonstrated that PPI may inhibit the cancerous inhibitor of protein phosphatase 2A (CIP2A)/protein phosphatase 2A (PP2A)/ERK axis, downregulate the expression of MMP7, vimentin, and Snail, and suppress tumor invasion and EMT. A PC xenograft mouse model was employed and the results revealed that PPI may decrease tumor growth and weight. Additionally, PPI may inhibit proliferating cell nuclear antigen expression and CIP2A/PP2A/ERK signaling pathway in PPI-treated tumors. Therefore, the results of the present study suggest that PPI may suppress the growth, invasion and EMT of PC cells via inhibition of CIP2A/PP2A/ERK signaling axis. As a result, PPI may be a novel target for the treatment of PC.

Abstract
BACKGROUND Quinalizarin (1,2,5,8-tetrahydroxyanthraquinone) exhibits potentially useful anticancer effects by inducing apoptosis in several types of cancer, but its underlying mechanism of action remains unknown. The present study examined the effects of quinalizarin on the induction of cell cycle arrest, apoptosis, the generation of reactive oxygen species (ROS), other underlying mechanisms, and its role in modifying colorectal cancer cell lines. MATERIAL AND METHODS The MTT assay was used to evaluate the viability of SW480 and HCT-116 cells that had been treated with quinalizarin and 5-fluorouracil (5-FU). Cell cycle arrest and apoptosis were analyzed by flow cytometry. Western blotting was used to investigate the mitochondrial pathway; Akt, MAPK, and STAT3 signaling pathways were also investigated. The relationship between ROS generation and apoptosis was analyzed by flow cytometry and western blotting. RESULTS The results indicated that quinalizarin significantly inhibits the viability of SW480 and HCT-116 cells in a dose-dependent manner. Quinalizarin induced SW480 cell cycle arrest at G2/M by regulating cyclin B1 and CDK1/2. The apoptosis-related protein expression levels of p-p53, Bad, cleaved caspase-3, cleaved PARP and p-JNK were increased in quinalizarin-treated cells, while protein expression levels Bcl-2, p-Akt, p-ERK, and p-STAT3 were decreased. Quinalizarin induced apoptosis in colorectal cancer cells by regulating MAPK and STAT3 signaling pathways via ROS generation. CONCLUSIONS Quinalizarin induces apoptosis via ROS-mediated MAPK/STAT3 signaling pathways.

Abstract
Piper longum L. is a well-known traditional antihyperlipidemic medicine in China, containing medicinal constituents of piperine, pipernonaline and piperlonguminine in its fruit. However, the antitumor properties of these constituents have not yet been studied. We found that potassium piperate (GBK), a derivative of piperine, inhibited proliferation of cancer cells. GBK selectively inhibited the G1-S-phase transition in breast cancer cells and the G1 arrest was correlated with induction of p27 expression, which is an inhibitor for cyclin-dependent kinases, and inhibition of cyclin A, cyclin E and cyclin B expression. Moreover, GBK treatment led to a downregulation of the mini-chromosome maintenance protein expression and induction of mitochondrial-dependent cell apoptosis in breast cancer cells. Our results also suggested that GBK might also inhibit cancer cell proliferation through epigenetic signaling pathways. A synergistic effect in inhibition of cancer cell proliferation was found when GBK was combined with chemotherapy medicines etoposide phosphate or cisplatin at middle or low doses in vitro. These results show that GBK is a novel potential anti-breast cancer drug that inhibits cell proliferation and promotes cell apoptosis.

Abstract
Plant natural products have long been considered to be important sources of bioactive molecules. A large number of antimicrobial and anticancer agents have been isolated form plants. In the present study we evaluated the antimicrobial and anticancer activity of a plant derived secondery metabolite, Polyphyllin G. The results of antibacterial assays showed that Polyphyllin G prevented the growth of both Gram-positive and Gram-negative bacteria with minimum inhibitory concentrations (MICs) ranging from 13.1 to 78 μg/ml. Antifungal activity measured as inhibition of mycelium growth ranged between 38.32 and 56.50%. Further Polyphyllin G was also evaluated against a panel of cancer cell lines. The IC50 of Polyphyllin G ranged from 10 to 65 μM. However the IC50 of Polyphyllin G was found to be comparatively high (120 μM) against the normal FR2 cancer cell line. The lowest IC50 of 10 μM was found against the oral cancer cell line OECM-1. Therefore further studies were carried out on this cell line only. Our results indicated that Polyphyllin G induced cell arrest in oral cancer OECM-1 cells by inactivation of cdc25C-cdc22 via ATM-Chk 1/2 stimulation. Therefore, we propose that Polyphyllin G might prove a lead molecule in the management of oral cancers and at the same time may prevent the growth of opportunistic microbes.

Abstract
OBJECTIVE To investigate quinalizarin-induced apoptosis in gastric cancer cells in vitro and explore the molecular mechanisms. METHODS MTT assay was used to determine the cytotoxic effects of quinalizarin on human gastric cancer AGS, MKN-28 and MKN-45 cells. Annexin V-FITC/PI staining and flow cytometry were used to assess quinalizarin-induced apoptosis in AGS cells and its effect on intracellular ROS levels; the expression levels of apoptotic proteins in the cells were determined with Western blotting. RESULTS Quinalizarin dose-dependently reduced the cell viabilities of the 3 gastric cancer cells (P<0.05). The IC50 values of quinalizarin in AGS, MKN-28 and MKN-45 cells were 7.07 µmol/L, 22.55 µmol/L and 14.18 µmol/L, respectively. Quinalizarin time-dependently induced apoptosis of AGS cells and potentiated the generation of intracellular reactive oxygen species (ROS) levels. Pretreatment with NAC, a scavenger of ROS, inhibited quinalizarin-induced apoptosis (P<0.001). Western blotting results showed that quinalizarin also up-regulated the expression levels of the apoptotic proteins including p-p38, p-JNK, Bad, cleaved caspase-3, and cleaved PARP-1 (P<0.05), and down-regulated the expression of the anti-apoptotic proteins p-Akt, p-ERK, and Bcl-2 (P<0.05). CONCLUSION Quinalizarin inhibits the proliferation and induces apoptosis in gastric cancer cells in vitro through regulating intracellular ROS levels via the MAPK and Akt signaling pathways.

Abstract
JNKs (c-Jun N-terminal kinases) belong to mitogen-activated protein kinases' family and become activated by several growth factors, stress, radiation, and other extracellular signals. In turn, JNK activation results in phosphorylation of downstream molecules involved in many normal cellular processes. Nevertheless, recent data have linked JNK signaling with several pathological conditions, including neurodegenerative diseases, inflammation, and cancer. The role of JNK in cancer remains controversial. Initially, JNK was thought to play a rather oncosuppressive role by mediating apoptosis in response to stress stimuli, inflammatory, or oncogenic signals. However, a number of studies have implicated JNK in malignant transformation and tumor growth. The contradictory functions of JNK in cancer may be due to the diversity of JNK upstream and downstream signaling and are under intensive investigation. This review summarizes current literature focusing on the significance of JNK pathway in cancer development and progression, particularly addressing its role in oral cancer. Understanding the complexity of JNK signaling has the potential to elucidate important molecular aspects of oral cancer, possibly leading to development of novel and individualized therapeutic strategies.

Abstract
Blockade of EGFR with reversible EGFR tyrosine kinase inhibitors (TKIs) is considered the frontline strategy for advanced NSCLC with EGFR mutations. However, acquired resistance to EGFR-TKI has been observed, resulting in disease progression and limited clinical benefit. Polyphyllin VII is the main member of polyphyllin family, which has been demonstrated to show strong anticancer activity against carcinomas. The sensitizing effect and underlying mechanism of Polyphyllin VII against acquired EGFR-TKI resistant NSCLC are still unexplored. In the present study, we aim to examined the sensitizing effect of Polyphyllin VII to gefitinib by modulating P21 signaling pathway in gefitinib acquired resistant NSCLC in vitro and in vivo. Gefitinib sensitive PC-9 cells and gefitinib acquired resistant H1975 cells were used. Cell proliferation and Clonogenic assay, Cell cycle analysis, Western blotting analysis and xenograft treatment were carried out. Polyphyllin VII enhanced the anti-proliferative effects of gefitinib and gefitinib-induced G1 phase arrest by modulation of P21 signaling pathway in acquired gefitinib resistant cells in vitro and in vivo. Polyphyllin VII elevated sensitization of gefitinib acquired resistant NSCLC cells to gefitinib through G1 phase arrest and modulation of P21 signaling pathway. It provides a potential new strategy to overcome gefitinib acquired resistance for EGFR-TKI resistant NSCLC.

Abstract
Radiotherapy is a powerful tool in the treatment of cancer that has the advantage of preserving normal tissues. However, tumor radioresistance currently remains a major impediment to effective RT. Thus, exploring effective radiation sensitizers is urgently needed. In this study, we have shown that diosmetin, the aglycone of the lavonoid glycoside from olive leaves, citrus fruits and some medicinal herbs, has a promising effect on radiotherapy sensitization. In our results, DIO could induce G1 phase arrest and thus enhance the radiosensitivity of radioresistant A549/IR lung cancer cells. Furthermore, DIO also restrains the IR-induced DNA damage repair by inhibiting the activated Akt signaling pathway. The combination of Akt inhibition (DIO, LY294002 or MK-2206) and radiation potently blocked A549/IR cancer cell proliferation. In summary, these observations suggest that the natural compound DIO could act as a potential drug for the treatment of radioresistant lung cancer cells.

Abstract
Methyl protodioscin (MPD), a furostanol saponin derived from the rhizomes of Dioscorea collettii var. hypoglauca (Dioscoreaceae), has been shown to exhibit broad bioactivities such as anti-inflammation and antitumor activities. Here, we explored the molecular mechanisms by which MPD induced apoptosis in MG-63 cells. The data showed that MPD significantly suppressed cell growth (cell viabilities: 22.5 ± 1.9% for 8 μM MPD versus 100 ± 1.4% for control, P < 0.01) and enhanced cell apoptosis. The exposure to MPD resulted in a significant induction of reactive oxygen species, loss of mitochondrial membrane potential, and activation of caspase-9 and caspase-3 (P < 0.01, all cases). Furthermore, treatment with MPD increased the levels of phosphorylated JNK and p38 MAPK and markedly decreased the levels of phosphorylated ERK in MG-63 cells. Co-administration of the JNK-specific antagonist, the p38-specific antagonist, or the caspase antagonist (P < 0.05, all cases) has reversed the apoptotic effects in MPD treatment. We also found that exposure to MPD resulted in a significant reduction in the protein level of anti-apoptotic proteins Bcl-2, survivin, and XIAP (P < 0.05, all cases). In conclusion, our results indicate that MPD induces apoptosis of human osteosarcoma MG-63 cells, at least in part, by caspase-dependent and MAPK signaling pathways.

Abstract
The envelope (Env) of Jaagsiekte sheep retrovirus (JSRV) is an oncoprotein of ovine pulmonary adenocarcinoma (OPA). Autophagy is involved in different cancers, but how it is carcinogenic in JSRV Env is unclear. Modulation of autophagy in exJSRV-env-NM-transfected cells through the Akt/mTOR and MAPK signaling pathway was studied, and we observed strong positive labeling of p-Akt, p-mTOR, p-MEK1/2, p-ERK1/2, p-p38 and p-JNK in tumor cells and typical type II pneumocytes in naturally infected OPA lung tissues, which was co-aligned with JSRV-Env positive cells as shown by immunohistochemical and microscopic analysis. Akt/mTOR and MAPK pathways were activated in OPA lung and JSRV-Env transfected NIH 3T3 cells. Decreased Beclin1 and LC3 II/I suggested that autophagy was inhibited in OPA lung and JSRV-Env transfected NIH 3T3 cells. Beclin1 and LC3 II/I increased in JSRV-Env transfected NIH3T3 cells treated with mTOR inhibitor (rapamycin), ERK1/2 inhibitor (PD 98059), p38 inhibitor (SB 203580) and JNK inhibitor (SP 600125), suggesting that Akt/mTOR and MAPK pathways were responsible for JSRV-Env decreased autophagy. In conclusion, JSRV Env decreased autophagy in JSRV-Env transfected NIH3T3 cells through Akt/mTOR and MAPK pathways, in particular, JNK and p38 pathways.

Abstract
During embryonic development, undifferentiated progenitor cells balance the generation of additional progenitor cells with differentiation. Within the developing limb, cartilage cells differentiate from mesodermal progenitors in an ordered process that results in the specification of the correct number of appropriately sized skeletal elements. The internal pathways by which these cells maintain an undifferentiated state while preserving their capacity to differentiate is unknown. Here, we report that the arginine methyltransferase PRMT5 has a crucial role in maintaining progenitor cells. Mouse embryonic buds lacking PRMT5 have severely truncated bones with wispy digits lacking joints. This novel phenotype is caused by widespread cell death that includes mesodermal progenitor cells that have begun to precociously differentiate into cartilage cells. We propose that PRMT5 maintains progenitor cells through its regulation of Bmp4 Intriguingly, adult and embryonic stem cells also require PRMT5 for maintaining pluripotency, suggesting that similar mechanisms might regulate lineage-restricted progenitor cells during organogenesis.
