Abstract
A new triterpene, aculeastrumone A (1), a new triterpene saponin aculeastrumoside A (2), and eleven known compounds (3-13) were isolated from MeOH/Water (80/20) extract of the fruits of Solanum aculeastrum (Solanaceae). Their structures were established by detailed 1D and 2D NMR spectroscopic studies and mass spectrometry. The isolated compounds were evaluated against three human cancer cells ((MCF-7 (breast cancer), NCI-H460 (lung cancer), and Hela (cervical cancer)) and normal human fibroblast (BJ) cell lines. Among them, saponins 2-5, 7-8, and Carpesterol 10 possess significant cytotoxic activity with IC50 ≤ 10 µM against the three cancer cell lines.

Abstract
The genera Dipsacus L. and Scabiosa L. of the Caprifoliaceae family are widely distributed in Europe, Asia, and Africa. This work reviews the available literature on the phytochemical profiles, ethnomedicinal uses, and biological activities of the most popular species. These plants are rich sources of many valuable specialized metabolites with beneficial medicinal properties, such as triterpenoid derivatives, iridoids, phenolic acids, and flavonoids. They are also sources of essential oils. The genus Dipsacus has been used for centuries in Chinese and Korean folk medicines to treat bone (osteoporosis) and joint problems (rheumatic arthritis). The Korean Herbal Pharmacopoeia and Chinese Pharmacopoeia include Dipsaci radix, the dried roots of D. asperoides C.Y.Cheng & T.M.Ai. In addition, S. comosa Fisch. ex Roem & Schult. and S. tschiliiensis Grunning are used in traditional Mongolian medicine to treat liver diseases. The current scientific literature data indicate that these plants and their constituents have various biological properties, including inter alia antiarthritic, anti-neurodegenerative, anti-inflammatory, antioxidant, anticancer, and antimicrobial activities; they have also been found to strengthen tendon and bone tissue and protect the liver, heart, and kidney. The essential oils possess antibacterial, antifungal, and insecticidal properties. This paper reviews the key biological values of Dipsacus and Scabiosa species, as identified by in vitro and in vivo studies, and presents their potential pharmacological applications.

Abstract
Ellagic acid (EA), found in fruits and foods, has been shown to be effective in the treatment of breast, colon and bladder cancer. However, due to the complexity of colon cancer, the therapeutic mechanism of EA for colon cancer is still unclear. Cell Counting Kit-8 (CCK-8) assay were employed to investigate the cell proliferation. Western blotting and flow cytometry assays were utilized to investigate apoptosis and autophagy in CRC cells (HCT116), respectively. Moreover, western blotting and luciferase reporter assays were evaluated the effect of EA on AMPK/mTOR pathway. Through flow cytometry analysis, EA could promote the apoptosis of HCT116 cells. In addition, EA can reduce the phosphorylation of mTOR, promoted phosphorylation of AMPK, and induced autophagy in HCT116 cells. Also, Dorsomorphin pretreatment can reduce the expression of autophagy protein, which indicates that EA induces autophagy through AMPK/mTOR pathway. These results suggest that EA inhibits the growth of colon cancer through AMPK/mTOR pathway and induces apoptosis and protective autophagy.

Cell Oncol 2022; 45:1073-1117. [PMID: 36149600 DOI: 10.1007/s13402-022-00715-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/03/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Gastric cancer imposes a substantial global health burden despite its overall incidence decrease. A broad spectrum of inherited, environmental and infectious factors contributes to the development of gastric cancer. A profound understanding of the molecular underpinnings of gastric cancer has lagged compared to several other tumors with similar incidence and morbidity rates, owing to our limited knowledge of the role of carcinogens in this malignancy. The International Agency for Research on Cancer (IARC) has classified gastric carcinogenic agents into four groups based on scientific evidence from human and experimental animal studies. This review aims to explore the potential comprehensive molecular and biological impacts of carcinogens on gastric cancer development and their interactions and interferences with various cellular signaling pathways. CONCLUSIONS In this review, we highlight recent clinical trial data reported in the literature dealing with different ways to target various carcinogens in gastric cancer. Moreover, we touch upon other multidisciplinary therapeutic approaches such as surgery, adjuvant and neoadjuvant chemotherapy. Rational clinical trials focusing on identifying suitable patient populations are imperative to the success of single-agent therapeutics. Novel insights regarding signaling pathways that regulate gastric cancer can potentially improve treatment responses to targeted therapy alone or in combination with other/conventional treatments. Preventive strategies such as control of H. pylori infection through eradication or immunization as well as dietary habit and lifestyle changes may reduce the incidence of this multifactorial disease, especially in high prevalence areas. Further in-depth understanding of the molecular mechanisms involved in the role of carcinogenic agents in gastric cancer development may offer valuable information and update state-of-the-art resources for physicians and researchers to explore novel ways to combat this disease, from bench to bedside. A schematic outlining of the interaction between gastric carcinogenic agents and intracellular pathways in gastric cancer H. pylori stimulates multiple intracellular pathways, including PI3K/AKT, NF-κB, Wnt, Shh, Ras/Raf, c-MET, and JAK/STAT, leading to epithelial cell proliferation and differentiation, apoptosis, survival, motility, and inflammatory cytokine release. EBV can stimulate intracellular pathways such as the PI3K/Akt, RAS/RAF, JAK/STAT, Notch, TGF-β, and NF-κB, leading to cell survival and motility, proliferation, invasion, metastasis, and the transcription of anti-apoptotic genes and pro-inflammatory cytokines. Nicotine and alcohol can lead to angiogenesis, metastasis, survival, proliferation, pro-inflammatory, migration, and chemotactic by stimulating various intracellular signaling pathways such as PI3K/AKT, NF-κB, Ras/Raf, ROS, and JAK/STAT. Processed meat contains numerous carcinogenic compounds that affect multiple intracellular pathways such as sGC/cGMP, p38 MAPK, ERK, and PI3K/AKT, leading to anti-apoptosis, angiogenesis, metastasis, inflammatory responses, proliferation, and invasion. Lead compounds may interact with multiple signaling pathways such as PI3K/AKT, NF-κB, Ras/Raf, DNA methylation-dependent, and epigenetic-dependent, leading to tumorigenesis, carcinogenesis, malignancy, angiogenesis, DNA hypermethylation, cell survival, and cell proliferation. Stimulating signaling pathways such as PI3K/Akt, RAS/RAF, JAK/STAT, WNT, TGF-β, EGF, FGFR2, and E-cadherin through UV ionizing radiation leads to cell survival, proliferation, and immortalization in gastric cancer. The consequence of PI3K/AKT, NF-κB, Ras/Raf, ROS, JAK/STAT, and WNT signaling stimulation by the carcinogenic component of Pickled vegetables and salted fish is the Warburg effect, tumorigenesis, angiogenesis, proliferation, inflammatory response, and migration.

CWHM-1008 Induces Apoptosis and Protective Autophagy through the Akt/mTOR Axis in LUAD Cells. JOURNAL OF ONCOLOGY 2022; 2021:5548128. [PMID: 35096055 PMCID: PMC8799368 DOI: 10.1155/2021/5548128] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Revised: 08/23/2021] [Accepted: 08/31/2021] [Indexed: 12/14/2022]
Abstract
Recent studies have revealed that antiparasitic agents showed promising inhibitory effects on tumors, raising a possibility that repositioning this class of drugs may shed new light on clinical therapy against tumors. CWHM-1008 is a novel class of antimalarial drug; however, the inhibitory impact of CWHM-1008 on lung adenocarcinoma (LUAD) cells remains unclear. This study aimed to explore the anticancer effect and underlying mechanisms of CWHM-1008 on LUAD cells in vitro and in vivo. Human LUAD cells, H358 and A549, were treated with varying concentrations of CWHM-1008 at different lengths of time. Cell viability, colony formation, cell count, flow cytometry findings, microtubule-associated protein-1 light chain 3-green- (LC3-) GFP/RFP adenovirus infection status, and the expression of apoptosis and autophagy-related proteins were examined. Potential effects of an autophagy inhibitor (LY294002) and constitutively active Akt plasmid (CA-Akt) on CWHM-1008-induced apoptosis were also examined. Our results showed that CWHM-1008 significantly inhibited proliferation, induced apoptosis, and enhanced autophagy flux by blocking the RAC-alpha serine/threonine-protein kinase/the mammalian target of rapamycin (Akt/mTOR) axis in two LUAD cells. In addition, autophagy inhibited by LY294002 or CA-Akt transfection accelerated CWHM-1008-induced apoptosis in those LUAD cells. Moreover, CWHM-1008 significantly inhibited the growth and induced apoptosis of A549 cell in nude mice in vivo. The present findings provide new insights into anticancer properties of CWHM-1008, suggesting that it may be an adjuvant treatment for LUAD treatment, warranting further study.

Abstract
PURPOSE Uveal melanoma is the most common primary intraocular tumour in adults. There is no standard adjuvant treatment to prevent metastasis and no effective therapy in the metastatic setting. (-)-4-O-(4-O-β-D-glucopyranosylcaffeoyl) quinic acid (QA) is a new compound isolated from the endophytic fungus Penicillium sp.FJ-1 of Avicennia marina, with potent activities to inhibit the PI3K. Our work further investigated effects of QA against uveal melanoma and explored its underlying mechanisms. METHODS MP65 cells were treated with QA at different concentrations. CCK-8 assay was used to detect effects of QA on cell viability. PI staining was used to detect cell cycle arrest. Tumour model was established by injecting MP65 cells into nude mice subcutaneously. Tumour-bearing mice were divided into three groups (5 mice per group). Mice were treated with QA (5 or 10 mg/kg) or saline by intraperitoneal injection five times per week. RT-qPCR and western blot were used to detect the expression of genes and proteins, respectively. RESULTS QA significantly inhibited the proliferation of uveal melanoma cells and induced the cell cycle arrest as well as autophagy. Moreover, QA treatment significantly slowed tumour growth of uveal melanoma, shown by decreased tumour volume and weight. Furthermore, QA treatment markedly decreased the protein expression of p-PI3K and p-AKT in tumour tissues. CONCLUSIONS Our data provided scientific rationale to develop QA as a promising anti-tumour agent against uveal melanoma.

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
C21 steroidal glycosides have been extensively reported for treating several types of cancer and are widely found in Marsdenia tenacissima. In this study, a C21 fraction was synthesized from M. tenacissima, and its anti-cancer potency was assessed against in vitro gastric cell lines BGC-823, SGC-7901, and AGS. Significant growth inhibition and cell cycle arrest were observed in C21 fraction-treated gastric cancer cells. The results of apoptotic staining techniques in C21 fraction-treated gastric cells were confirmed with excess reactive oxygen species generation. Moreover, SOD and H2O2 levels were increased by C21 fraction, especially when combined with chloroquine (CQ). The apoptotic inducing potential of C21 fraction was also evidenced by upregulation of proapoptotic proteins cleaved-PARP and BAX and downregulation of antiapoptotic proteins Bcl-2 and p-AKT by western blot, especially in the presence of the autophagy inhibitor CQ. The results showed that the apoptosis of gastric cancer cells caused by C21 fraction was enhanced by inhibiting autophagy. The current findings reveal a new mechanism for the antitumor activity of C21 fraction on gastric cancer.

Indomethacin can induce cell death in rat gastric parietal cells through alteration of some apoptosis- and autophagy-associated molecules. Int J Exp Pathol 2020; 101:230-247. [PMID: 32985762 DOI: 10.1111/iep.12370] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2018] [Revised: 06/13/2020] [Accepted: 07/01/2020] [Indexed: 12/14/2022] Open
Abstract
In clinical medicine, indomethacin (IND, a non-steroidal anti-inflammatory drug) is used variously in the treatment of severe osteoarthritis, rheumatoid arthritis, gouty arthritis or ankylosing spondylitis. A common complication found alongside the therapeutic characteristics is gastric mucosal damage. This complication is mediated through apoptosis and autophagy of the gastrointestinal mucosal epithelium. Apoptosis and autophagy are critical homeostatic pathways catalysed by caspases downstream of the gastrointestinal mucosal epithelial injury. Both act through molecular signalling pathways characterized by the initiation, mediation, execution and regulation of the cell regulatory cycle. In this study we hypothesized that dysregulated apoptosis and autophagy are associated with IND-induced gastric damage. We examined the spectra of in vivo experimental gastric ulcers in male Sprague-Dawley rats through gastric gavage of IND. Following an 18-hour fast, IND was administered to experimental rats. They were sacrificed at 3-, 6- and 12-hour intervals. Parietal cells (H+ , K+ -ATPase β-subunit assay) and apoptosis (TUNEL assay) were determined. The expression of apoptosis-signalling caspase (caspases 3, 8, 9 and 12), DNA damage (anti-phospho-histone H2A.X) and autophagy (MAP-LC3, LAMP-1 and cathepsin B)-related molecules in gastric mucosal cells was examined. The administration of IND was associated with gastric mucosal erosions and ulcerations mainly involving the gastric parietal cells (PCs) of the isthmic and upper neck regions and a time-dependent gradual increase in the number of apoptotic PCs with the induction of both apoptotic (upregulation of caspases 3 and 8) cell death and autophagic (MAP-LC3-II, LAMP-1 and cathepsin B) cell death. Autophagy induced by fasting and IND 3 hours initially prompted the degradation of caspase 8. After 6 and 12 hours, damping down of autophagic activity occurred, resulting in the upregulation of active caspase 8 and its nuclear translocation. In conclusion we report that IND can induce time-dependent apoptotic and autophagic cell death of PCs. Our study provides the first indication of the interactions between these two homeostatic pathways in this context.

Holistic approach to microwave-reflux extraction and thermo-analytical fingerprints of under-utilized Artocarpus heterophyllus seed wastes. Heliyon 2020; 6:e04770. [PMID: 32923719 PMCID: PMC7475185 DOI: 10.1016/j.heliyon.2020.e04770] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2020] [Revised: 05/07/2020] [Accepted: 08/19/2020] [Indexed: 12/03/2022] Open
Abstract
The increase in wastes generated from jackfruit seeds has been largely under-utilized in Malaysia. Due to the high nutritional and medicinal content embedded in the cellulosic structure of jackfruit wastes, a need then arises for their physicochemical elucidations. In this study, the extraction of Artocarpus heterophyllus seed was carefully investigated using Taguchi orthogonal optimization design. Complete functional group characteristics and chemical profile of the A. heterophyllus seed extracts were obtained using different physicochemical characterization. The optimal conditions of the microwave extraction parameters were determined at 5 min of irradiation time, 450 W of power and 50 °C of temperature. Under this condition, the optimal yield of 17.34 (mg/g) % was achieved at an SNR ratio of 24.78. The mass spectrometry analysis tentatively identified a total of 90 and 148 secondary metabolites at positive and negative ESI modes, respectively. The chemical profile obtained provided a baseline reference for further investigation on the food and medicinal bioactive from Artocarpus heterophyllus seed oleoresins. The FT-infrared emission spectrum shows the presence of some specific carbohydrates and amide protein functional groups directly linked to C–O (1008 cm−1) the carbonyl (C=O) groups, respectively. Moreover, the morphological characteristics of the jackfruit raw and crude extracts conspicuously revealed large-sized globules which suggest the carbohydrates and protein contents. The result of this study indicates that the use of microwave extraction technology produced high-quality extracts with lower degradation of the thermal labile constituents. This will assist in determining the suitable conditions necessary for the total recovery of medicinal and nutritional constituents and conversion of agricultural waste products into useful products.

Abstract
Autophagy, an intricate response to nutrient deprivation, pathogen infection, Endoplasmic Reticulum (ER)-stress and drugs, is crucial for the homeostatic maintenance in living cells. This highly regulated, multistep process has been involved in several diseases including cardiovascular and neurodegenerative diseases, especially in cancer. It can function as either a promoter or a suppressor in cancer, which underlines the potential utility as a therapeutic target. In recent years, increasing evidence has suggested that many natural products could modulate autophagy through diverse signaling pathways, either inducing or inhibiting. In this review, we briefly introduce autophagy and systematically describe several classes of natural products that implicated autophagy modulation. These compounds are of great interest for their potential activity against many types of cancer, such as ovarian, breast, cervical, pancreatic, and so on, hoping to provide valuable information for the development of cancer treatments based on autophagy.

Abstract
Species of Dipsacus have been widely used in folk medicine for their neuroprotective, antiosteoporotic, antioxidative, anticomplementary, and antibacterial activities. However, there has been but a limited amount of research on the anticancer effect of one of the most popular representatives of this genus, D. fullonum. Also, the cytotoxic activity has not yet been investigated of the constituents of D. fullonum leaves. The purpose of this study was to evaluate the cytotoxic activity of the bis-iridoid glycosides isolated from D. fullonum leaves against murine fibroblast NIH/3T3, mouse melanoma B16F10, HeLa human cervical cancer, human breast cancer MCF7 and MDB-MB-231 cells. The bis-iridoids, obtained by chromatographic fractionation of the extract of D. fullonum leaves, were characterized by thin-layer chromatography and high-performance liquid chromatography-mass spectrometry (HPLC-MS)/MS analysis. The cytotoxicity of the iridoid fraction was evaluated by WST-1 assay, and the number of dead cells was determined by the propidium iodide test. HPLC-MS/MS analysis showed the isolated bis-iridoid fraction to consist mainly of sylvestroside III and/or sylvestroside IV. This fraction was applied to cell cultures and kept for 48 and 72 hours. The results demonstrated that the iridoid glycosides had a differential ability to induce cell death in normal and cancer cells. The study confirmed that the bis-iridoids extracted from D. fullonum leaves had a selective cytotoxic effect on human breast cancer cell lines MCF7 and MDB-MD-231, while their cytotoxic effect on noncancer cells was low.

Abstract
Gastric cancer (GC) is the fifth most frequently diagnosed cancer and the third leading cause of cancer death. Approximately 15% of GC is associated with Epstein-Barr virus (EBV). GC is largely incurable with a dismal five-year survival rate. There is an urgent need to identify new therapeutic agents for the treatment of GC. Tenovin-6 was initially identified as a p53 activator, but it was later found to inhibit autophagy flux, and the protein deacetylase activity of sirtuins. Tenovin-6 shows promising therapeutic effect in various malignancies. However, it remains unknown whether Tenovin-6 is effective for GC. In this study, we found that EBV-positive and -negative GC cell lines were sensitive to Tenovin-6 but with different response times and doses. Tenovin-6 suppressed anchorage-independent growth of GC cells. Tenovin-6 induced different levels of apoptosis and phases of cell-cycle arrest depending on the cell lines with some manifesting gap 1 (G1) and others showing synthesis (S) phase cell-cycle arrest. Mechanistically, Tenovin-6 induced autophagy or p53 activation in GC cells depending on the status of TP53 gene. However, initiation of autophagy following treatment with Tenovin-6 conferred some protective effect on numerous cells. Combined treatment with Tenovin-6 and autophagy inhibitor chloroquine increased the cytotoxic effect by inducing microtubule-associated protein 1 light chain 3B (LC3B)-II accumulation, and by enhancing apoptosis and cell-cycle arrest. These results indicated that Tenovin-6 can be used as a potential therapeutic agent for GC, but the genetic background of the cancer cells might determine the response and mechanism of action. Treatment with Tenovin-6 alone or in combination with chloroquine could be a promising therapeutic approach for GC.

Biomed Pharmacother 2019; 122:109726.

Abstract
Salidroside, a natural active ingredient extracted from Rhodiola rosea, has been shown to exert antitumor activity against breast cancer Dong Young et al. [1], colon cancer Sun et al. [2] and bladder cancer Tian et al. [3]. However, the effect of salidroside on apoptosis and autophagy in gastric cancer remains unclear. In our research, we observed the biological effect of salidroside on human gastric cancer AGS cells. Our results demonstrated that salidroside inhibited the growth of AGS cells both in vivo and in vitro and exerted a proapoptotic effect on AGS cells as confirmed by flow cytometry, Hoechst staining and western blot analysis. Additionally, we found that salidroside decreased the phosphorylation of PI3K and Akt and that pretreatment with the PI3K/Akt agonist IGF-1 could weaken the proapoptotic effect of salidroside. Interestingly, the exposure of AGS cells to salidroside induced autophagy as indicated by transmission electron microscopy, mRFP-GFP-LC3 transfection and western blot analysis, suggesting that salidroside promoted autophagy in gastric cancer AGS cells. Furthermore, treatment with the autophagy inhibitor chloroquine enhanced salidroside-induced cell apoptosis, indicating that the autophagy mediated by salidroside may protect AGS cells from death. Additionally, we found that salidroside decreased the level of p-mTOR protein in a concentration-dependent manner and that pretreatment with IGF-1 decreased the expression of autophagy proteins, suggesting that salidroside induced autophagy through the PI3K/Akt/mTOR pathway. The above findings indicate that salidroside inhibited the growth of gastric cancer and induced apoptosis and protective autophagy through the PI3K/Akt/mTOR pathway. In summary, our study provides novel insights regarding the activity of salidroside against gastric cancer and contributes to the clinical application of salidroside combined with autophagy inhibitors as a chemotherapeutic strategy for human gastric cancer.

Abstract
BACKGROUND In spite of major technological advances in conventional therapies, cancer continues to remain the leading cause of mortality worldwide. Phytochemicals are gradually emerging as a rich source of effective but safer agents against many life-threatening diseases. METHODS Various phytochemicals with reported anticancer activity have been simply categorized into major phytoconstituents- alkaloids, polyphenols, saponins, tannins and terpenoids. RESULTS The adverse effects associated with currently available anticancer medications may be overcome by using plant-derived compounds either alone or in combination. Exploration of plant kingdom may provide new leads for the accelerated development of new anticancer agents. CONCLUSION Although numerous potent synthetic drugs have been introduced for cancer chemotherapy, yet their serious toxicity concerns to normal cells apart from drug resistance have emerged as the major obstacles for their clinical utility over a prolonged duration of time. Current status and potential of phytochemicals and their derivatives in cancer therapy have been briefly reviewed in the present manuscript.

Abstract
Ginsenoside Rg5, a rare saponin belonging to the family of protopanaxadiol ginsenosides, has been demonstrated to have potential anti-tumor effects in various cancers. However, the effect of Rg5 on human gastric cancer and the underlying molecular mechanisms remain to be elucidated. In this study, Rg5 could suppress cell proliferation by causing G2/M phase arrest. Treatment with Rg5 could induce apoptosis through the extrinsic death receptor and intrinsic mitochondrial pathways. Autophagy induction was demonstrated by the formation of autophagosomes and autophagy-related proteins. Rg5-induced cell death was inhibited by the autophagy inhibitor 3-MA and apoptosis inhibitor Z-VAD-FMK. Moreover, the suppression of apoptosis weakened Rg5-induced autophagy, while the inhibition of autophagy attenuated Rg5-induced apoptosis. Further studies revealed that Rg5 induced ROS production and activated MAPK signaling pathways. The ROS scavenger NAC markedly diminished G2/M arrest, apoptosis, autophagy and activation of MAPK pathways induced by Rg5. The p38 inhibitor SB203580 or knockdown of p38 by siRNA clearly reversed Rg5-induced apoptosis and G2/M arrest. The JNK inhibitor SP600125 or knockdown of JNK by siRNA markedly attenuated Rg5-induced G2/M arrest, apoptosis and autophagy. The inhibition of ERK inhibitor U0126 or knockdown of ERK by siRNA clearly restored Rg5-induced apoptosis and autophagy. Finally, Rg5 significantly suppressed the growth of xenograft gastric tumors with fewer side effects. Overall, the evidence suggested that Rg5 is a novel and promising strategy for the treatment of gastric cancer owing to its high efficacy, multiple mechanisms and fewer side effects.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Dipsaci Radix, which is the dried root of Dipsacus asperoides C. Y. Cheng and T. M. Ai (Dipsacaceae), is used to treat back pain and blood stasis syndrome in Korean traditional medicine. AIM OF THE STUDY To understand the mechanisms responsible for the pharmacological activities of D. asperoides, we investigated the inhibitory effect of D. asperoides on lipopolysaccharide (LPS)-induced inflammation in mouse macrophages RAW 264.7 cells. MATERIALS AND METHODS Aqueous extract of D. asperoides (AEDA) was prepared by boiling D. asperoides in water and then administered to LPS treated RAW 264.7 cells. Cell viabilities were measured using an MTT assay, and protein levels were determined by western blotting. The ROS scavenging activity of AEDA was measured using a DCFH-DA assay and levels of nitric oxide (NO) were determined using a NO assay. The nuclear translocations of NF-κB and Nrf2 were investigated immunocytochemically, and pro-inflammatory cytokines in supernatant were evaluated by ELISA. RESULTS Treatment with AEDA suppressed the expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in LPS-stimulated RAW 264.7 macrophages. AEDA also reduced ROS, pro-inflammatory cytokine (IL-6 and IL-1β) levels, and iNOS-derived NO and COX-2-derived prostaglandin E2 release to medium, and suppressed the phosphorylation and degradation of IκB and the activation of NF-κB in macrophages. Furthermore, treatment with AEDA inhibited the ERK1/2 pathway but not the JNK or p38 MAPK pathways. In addition, AEDA significantly promoted Nrf2 translocation from cytoplasm to nucleus and up-regulated the expression of HO-1. CONCLUSION These results suggest that AEDA has anti-inflammatory and anti-oxidative effects through the inhibition of NF-κB and ERK1/2 and the activation of Nrf2/HO-1 in macrophages.

Abstract
Autophagy, which is tightly regulated by a series of autophagy-related genes (ATGs), is a vital intracellular homeostatic process through which defective proteins and organelles are degraded and recycled under starvation, hypoxia or other specific cellular stress conditions. For both normal cells and tumour cells, autophagy not only sustains cell survival but can also promote cell death. Autophagy-related signalling pathways include mTOR-dependent pathways, such as the AMPK/mTOR and PI3K/Akt/mTOR pathways, and non-mTOR dependent pathways, such as the P53 pathway. Additionally, autophagy plays a dual role in gastric carcinoma (GC), including a tumour-suppressor role and a tumour-promoter role. Long-term Helicobacter pylori infection can impair autophagy, which may eventually promote tumourigenesis of the gastric mucosa. Moreover, Beclin1, LC3 and P62/SQSTM1 are regarded as autophagy-related markers with GC prognostic value. Autophagy inhibitors and autophagy inducers show promise for GC treatment. This review describes research progress regarding autophagy and its significant role in gastric cancer.

[PMID: 30127963 PMCID: PMC6096173 DOI: 10.3892/ol.2018.9101] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2018] [Accepted: 07/03/2018] [Indexed: 12/11/2022] Open
Abstract
Ailanthone, which is extracted from the traditional Chinese medicinal plant Ailanthus altissima, has been thoroughly demonstrated to have anti-tumor, anti-HIV, anti-inflammatory, anti-malarial, anti-allergic and anti-microbial activities. However, the anti-proliferative effects of ailanthone on HL-60 cells and potential mechanisms underlying those effects have not been reported. In the present study, we demonstrated the potent cytotoxicity of ailanthone against HL-60 cells. Annexin V-APC/7-ADD staining assay indicated that ailanthone increased the number of apoptotic cells in a dose-dependent manner. PI staining showed that ailanthone increased the percentage of G0/G1-phase cells in a dose-dependent manner. Acridine orange staining suggested that ailanthone induced the formation of acidic vesicular organelles in HL-60 cells and pretreatment with BaF-A1 could attenuate this process. Western blotting showed that ailanthone up-regulated the protein expression levels of beclin-1 and LC3-II and down-regulated those of LC3-I and p62 in a dose-dependent manner. Use of BaF-A1 showed that the anti-proliferative effects of ailanthone on HL-60 cells may be partly attributable to the induction of autophagy-mediated apoptosis by MTT assay and annexin V-APC/7-ADD staining assay.

DSGOST regulates resistance via activation of autophagy in gastric cancer. Cell Death Dis 2018; 9:649. [PMID: 29844404 PMCID: PMC5974125 DOI: 10.1038/s41419-018-0658-y] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2017] [Revised: 04/20/2018] [Accepted: 04/23/2018] [Indexed: 12/11/2022]
Abstract
Danggui-Sayuk-Ga-Osuyu-Saenggang-Tang (DSGOST in Korean, Danggui-Sini-Jia-Wuzhuyu-Shengian-Tang in Chinese, and Tokishigyakukagoshuyushokyoto (TJ-38) in Japanese), a well-known traditional Korean/Chinese/Japanese medicine, has long been used to treat vascular diseases such as Raynaud’s phenomenon (RP). However, anticancer effect of DSGOST remains elusive. In this study, we checked if DSGOST has an anticancer effect against gastric cancer cells, and investigated the mechanisms underlying DSGOST resistance. Moreover, DSGOST regulates chemoresistance in cisplatin-treated gastric cancer cells. Interestingly, DSGOST treatment induced the accumulation of GFP-LC3 puncta and increased the level of autophagy markers, such as LC3-II, ATG5, and Beclin-1, indicating activated autophagy. Furthermore, DSGOST could activate epithelial-to-mesenchymal transition (EMT) and exosomes via induction of autophagy. DSGOST in combination with TGFβ also induced autophagy and EMT. However, autophagy inhibition induces DSGOST-mediated cell death in gastric cancer cells. In addition, autophagy inhibition blocks the activation of DSGOST-mediated EMT markers including N-cadherin, Snail, Slug, vimentin, β-catenin, p-Smad2, and p-Smad3. Taken together, these findings indicated that prosurvival autophagy was one of the mechanisms involved in the resistance of gastric cancer to DSGOST. Targeting the inhibition of autophagy could be an effective therapeutic approach to overcome resistance to DSGOST in gastric cancer.

Crosstalk Influence between P38MAPK and Autophagy on Mitochondria-Mediated Apoptosis Induced by Anti-Fas Antibody/Actinomycin D in Human Hepatoma Bel-7402 Cells. Molecules 2017; 22:molecules22101705. [PMID: 29039784 PMCID: PMC6151482 DOI: 10.3390/molecules22101705] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2017] [Revised: 10/02/2017] [Accepted: 10/02/2017] [Indexed: 12/16/2022] Open
Abstract
Our previous study indicated that anti-Fas antibody/actinomycin D (AF/AD) induced apoptosis of human hepatocellular carcinoma Bel-7402 cells; however, crosstalk influence between P38MAPK and autophagy on mitochondria-mediated apoptosis induced by AF/AD in Bel-7402 cells remains unclear. Therefore, effect of AF/AD on apoptosis, autophagy, phosphorylated-P38MAPK (p-P38MAPK), and membrane potential (ΔΨm) with or without the P38MAPK inhibitor SB203580 or the autophagy inhibitor 3-methyladenine (3-MA) in Bel-7402 cells was investigated in the present study. The results showed that AF/AD resulted in induction of apoptosis concomitant with autophagy, upregulation of p-P38MAPK and autophagy-associated gene proteins (Atg5-Atg12 protein complex, Atg7, Atg10, Beclin-1, LC3 I, and LC3 II), and downregulation of ΔΨm in Bel-7402 cells. In contrast, SB203580 attenuated the effects of AF/AD in Bel-7402 cells. Furthermore, the findings also demonstrated that 3-MA inhibited the impact of AF/AD on autophagy, Atg5-Atg12 protein complex, Atg7, Atg10, Beclin-1, LC3 I, LC3 II, and ΔΨm, and promoted the influence of AF/AD on apoptosis and p-P38MAPK in Bel-7402 cells. Taken together, we conclude that crosstalk between P38MAPK and autophagy regulates mitochondria-mediated apoptosis induced by AF/AD in Bel-7402 cells.

Abstract
This study was conducted to investigate the cytotoxicity and apoptosis effect of A. crispa extract and its solvent partition (ethyl acetate and aqueous extract) against Mus musculus mammary carcinoma cell line (4T1). The normal mouse fibroblast cell line (NIH3T3) was used as comparison for selective cytotoxicity properties. The cytotoxicity evaluation was assessed using MTT assay. AO/PI dual fluorescent staining assay and Annexin V-FITC were used for apoptosis analysis. Results showed that 80% methanol extract from leaves showed most promising antimammary cancer agent with IC50 value of 42.26 ± 1.82 μg/mL and selective index (SI) value of 10.22. Ethyl acetate was cytotoxic for both cancer and normal cell while aqueous extract exhibited poor cytotoxic effect. 4T1 cells labelled with AO/PI and Annexin V-FITC and treated with 80% methanol extract demonstrated that the extract induces apoptosis to 4T1 mammary cancer cells. In conclusion, 80% methanol extract of A. crispa was selectively cytotoxic towards 4T1 cells but less cytotoxic towards NIH3T3 cells and induced the cancerous cells into apoptotic stage as early as 6 hours.

Abstract
Autophagy is a highly regulated catabolic pathway responsible for the degradation of long-lived proteins and damaged intracellular organelles. Perturbations in autophagy are found in gastric cancer. In host gastric cells, autophagy can be induced by Helicobacter pylori (or H. pylori) infection, which is associated with the oncogenesis of gastric cancer. In gastric cancer cells, autophagy has both pro-survival and pro-death functions in determining cell fate. Besides, autophagy modulates gastric cancer metastasis by affecting a wide range of pathological events, including extracellular matrix (ECM) degradation, epithelial-to-mesenchymal transition (EMT), tumor angiogenesis, and tumor microenvironment. In addition, some of the autophagy-related proteins, such as Beclin 1, microtubule-associated protein 1 light chain 3 (MAP1-LC3), and p62/sequestosome 1 (SQSTM1) have certain prognostic values for gastric cancer. In this article, we review the recent studies regarding the functional role of autophagy in gastric cancer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine (TCM), an ancient yet still alive medicinal system widely used in East Asia, has played an essential role in health maintenance and diseases control, for a wide range of human chronic diseases like cancers and neurodegenerative diseases. TCM-derived compounds and extracts attract wide attention for their potential application as therapeutic agents against above mentioned diseases. AIM OF REVIEW Recent years the enthusiasm in searching for autophagy regulators for human diseases has yielded many positive hits. TCM-derived compounds as important sources for drug discovery have been widely tested in different models for autophagy modulation. Here we summarize the current progress in the discovery of natural autophagy regulators from TCM for the therapeutic application in cancer and neurodegenerative disease models, aiming to provide the direct link from traditional use to new pharmacological application. METHODS The present review collected the literature published during the recent 10 years which studied the effect of TCM-derived compounds or extracts on autophagy regulation from PubMed, Web of Science, Google Scholar and Science Direct. The names of chemical compounds studied in this article are corresponding to the information in journal plant list. RESULTS In this review, we give a brief introduction about the autophagy and its roles in cancer and neurodegenerative disease models and describe the molecular mechanisms of autophagy modulation. We also make comprehensive lists to summarize the effects and underlying mechanisms of TCM-derived autophagy regulators in cancer and neurodegenerative disease models. In the end of the review, we discuss the current strategies, problems and future direction for TCM-derived autophagy regulators in the treatment of human diseases. CONCLUSIONS A number of data from in vivo and in vitro models indicated TCM derived compounds and extracts hold great potential for the treatment of human diseases including cancers and neurodegenerative diseases. Autophagy, as a novel and promising drug target involved in a wide range of human diseases, can be modulated by many TCM derived agents, indicating autophagy modulation may be an important mechanism underlying the therapeutic effect of TCM in treating diseases. Furthermore, we look forward to seeing the discovery of ideal autophagy modulators from TCM with considerably higher selectivity for the treatment of human diseases.

Induction of MAPK- and ROS-dependent autophagy and apoptosis in gastric carcinoma by combination of romidepsin and bortezomib. Oncotarget 2016; 7:4454-67.

Abstract
Proteasome inhibitors and histone deacetylase (HDAC) inhibitors can synergistically induce apoptotic cell death in certain cancer cell types but their combinatorial effect on the induction of autophagy remains unknown. Here, we investigated the combinatorial effects of a proteasome inhibitor, bortezomib, and an HDAC inhibitor, romidepsin, on the induction of apoptotic and autophagic cell death in gastric carcinoma (GC) cells. Isobologram analysis showed that low nanomolar concentrations of bortezomib/romidepsin could synergistically induce killing of GC cells. The synergistic killing was due to the summative effect of caspase-dependent intrinsic apoptosis and caspase-independent autophagy. The autophagic cell death was dependent on the activation of MAPK family members (ERK1/2 and JNK), and generation of reactive oxygen species (ROS), but was independent of Epstein-Barr virus infection. In vivo, bortezomib/romidepsin also significantly induced apoptosis and autophagy in GC xenografts in nude mice. This is the first report demonstrating the potent effect of combination of HDAC and proteasome inhibitors on the induction of MAPK- and ROS-dependent autophagy in addition to caspase-dependent apoptosis in a cancer type.

Abstract
Autophagy is a universal catabolic cellular process for quality control of cytoplasm and maintenance of cellular homeostasis upon nutrient deprivation and environmental stimulus. It involves the lysosomal degradation of cellular components such as misfolded proteins or damaged organelles. Defects in autophagy are implicated in the pathogenesis of diseases including cancers, myopathy, neurodegenerations, infections and cardiovascular diseases. In the recent decade, traditional drugs with new clinical applications are not only commonly found in Western medicines, but also highlighted in Chinese herbal medicines (CHM). For instance, pharmacological studies have revealed that active components or fractions from Chaihu (Radix bupleuri), Hu Zhang (Rhizoma polygoni cuspidati), Donglingcao (Rabdosia rubesens), Hou po (Cortex magnoliae officinalis) and Chuan xiong (Rhizoma chuanxiong) modulate cancers, neurodegeneration and cardiovascular disease via autophagy. These findings shed light on the potential new applications and formulation of CHM decoctions via regulation of autophagy. This article reviews the roles of autophagy in the pharmacological actions of CHM and discusses their new potential clinical applications in various human diseases.

Polyphyllin VII Induces an Autophagic Cell Death by Activation of the JNK Pathway and Inhibition of PI3K/AKT/mTOR Pathway in HepG2 Cells. PLoS One 2016; 11:e0147405. [PMID: 26808193 PMCID: PMC4726701 DOI: 10.1371/journal.pone.0147405] [Citation(s) in RCA: 56] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2015] [Accepted: 01/04/2016] [Indexed: 12/19/2022] Open
Abstract
Polyphyllin VII (PP7), a pennogenyl saponin isolated from Rhizoma Paridis, exhibited strong anticancer activities in various cancer types. Previous studies found that PP7 induced apoptotic cell death in human hepatoblastoma cancer (HepG2) cells. In the present study, we investigated whether PP7 could induce autophagy and its role in PP7-induced cell death, and elucidated its mechanisms. PP7 induced a robust autophagy in HepG2 cells as demonstrated by the conversion of LC3B-I to LC3B-II, degradation of P62, formation of punctate LC3-positive structures, and autophagic vacuoles tested by western blot analysis or InCell 2000 confocal microscope. Inhibition of autophagy by treating cells with autophagy inhibitor (chloroquine) abolished the cell death caused by PP7, indicating that PP7 induced an autophagic cell death in HepG2 cells. C-Jun N-terminal kinase (JNK) was activated after treatment with PP7 and pretreatment with SP600125, a JNK inhibitor, reversed PP7-induced autophagy and cell death, suggesting that JNK plays a critical role in autophagy caused by PP7. Furthermore, our study demonstrated that PP7 increased the phosphorylation of AMPK and Bcl-2, and inhibited the phosphorylation of PI3K, AKT and mTOR, suggesting their roles in the PP7-induced autophagy. This is the first report that PP7 induces an autophagic cell death in HepG2 cells via inhibition of PI3K/AKT/mTOR, and activation of JNK pathway, which induces phosphorylation of Bcl-2 and dissociation of Beclin-1 from Beclin-1/Bcl-2 complex, leading to induction of autophagy.

Abstract
To investigate signal regulation models of gastric cancer, databases and literature were used to construct the signaling network in humans. Topological characteristics of the network were analyzed by CytoScape. After marking gastric cancer-related genes extracted from the CancerResource, GeneRIF, and COSMIC databases, the FANMOD software was used for the mining of gastric cancer-related motifs in a network with three vertices. The significant motif difference method was adopted to identify significantly different motifs in the normal and cancer states. Finally, we conducted a series of analyses of the significantly different motifs, including gene ontology, function annotation of genes, and model classification. A human signaling network was constructed, with 1643 nodes and 5089 regulating interactions. The network was configured to have the characteristics of other biological networks. There were 57,942 motifs marked with gastric cancer-related genes out of a total of 69,492 motifs, and 264 motifs were selected as significantly different motifs by calculating the significant motif difference (SMD) scores. Genes in significantly different motifs were mainly enriched in functions associated with cancer genesis, such as regulation of cell death, amino acid phosphorylation of proteins, and intracellular signaling cascades. The top five significantly different motifs were mainly cascade and positive feedback types. Almost all genes in the five motifs were cancer related, including EPOR, MAPK14, BCL2L1, KRT18, PTPN6, CASP3, TGFBR2, AR, and CASP7. The development of cancer might be curbed by inhibiting signal transductions upstream and downstream of the selected motifs.

Abstract
We demonstrate that chikusetsusaponin IVa methyl ester (CME), a triterpenoid saponin from the root of Achyranthes japonica, has an anticancer activity. We investigate its molecular mechanism in depth in HCT116 cells. CME reduces the amount of β-catenin in nucleus and inhibits the binding of β-catenin to specific DNA sequences (TCF binding elements, TBE) in target gene promoters. Thus, CME appears to decrease the expression of cell cycle regulatory proteins such as Cyclin D1, as a representative target for β-catenin, as well as CDK2 and CDK4. As a result of the decrease of the cell cycle regulatory proteins, CME inhibits cell proliferation by arresting the cell cycle at the G0/G1 phase. Therefore, we suggest that CME as a novel Wnt/β-catenin inhibitor can be a putative agent for the treatment of colorectal cancers.

Abstract
Autophagy is a homeostatic process that is highly conserved across different types of mammalian cells. Autophagy is able to relieve tumor cell from nutrient and oxidative stress during the rapid expansion of cancer. Excessive and sustained autophagy may lead to cell death and tumor shrinkage. It was shown in literature that many anticancer natural compounds and extracts could initiate autophagy in tumor cells. As summarized in this review, the tumor suppressive action of natural products-induced autophagy may lead to cell senescence, provoke apoptosis-independent cell death, and complement apoptotic cell death by robust or target-specific mechanisms. In some cases, natural products-induced autophagy could protect tumor cells from apoptotic death. Technical variations in detecting autophagy affect data quality, and study focus should be made on elaborating the role of autophagy in deciding cell fate. In vivo study monitoring of autophagy in cancer treatment is expected to be the future direction. The clinical-relevant action of autophagy-inducing natural products should be highlighted in future study. As natural products are an important resource in discovery of lead compound of anticancer drug, study on the role of autophagy in tumor suppressive effect of natural products continues to be necessary and emerging.

Abstract
Gastric cancer is one of the most common malignant neoplasms. Surgery represents the main approach for this disease. Notwithstanding the advances in surgical techniques, there has been still a minimal improvement in overall survival with a significant increase in relapse rates. Although the development of new drugs has significantly improved the effectiveness of chemotherapy, the prognosis of patients with unresectable or metastatic gastric carcinoma remains poor. Therefore, it is necessary to find some new ways against gastric carcinogenesis. It has been shown that autophagy plays a dual role in the transformation and progression of gastric cancer; activation and induction of autophagy can lead to gastric carcinogenesis. Recently, several agents targeting autophagy molecules in gastric carcinogenesis have been investigated. This article reviews the regulation of autophagy with inhibitors or inducers to treat gastric cancer, and discusses how they regulate autophagy as a targeted therapy for gastric cancer.

Abstract
Metastasis is the main cause of mortality of patients with cancer-related disease. Targeting the process of metastasis has been proposed as a potential strategy in cancer treatment. Trillium tschonoskii Maxim., a traditional Chinese medicine, is used for the treatment of numerous diseases, including cancer. The current study aimed to determine the anti-metastatic effect of Paris saponin VII (PS VII), which was extracted from T. tschonoskii Maxim., using SW620 and LoVo cells, two human metastatic colorectal cancer (CRC) cell lines. The present study conducted cell attachment, wound healing and migration assays to detect the anti-metastatic effects of PS VII on colorectal cells. In addition, gelatin zymography assay and western blot analysis were used to detect the possible mechanisms involved. The results of this study demonstrated that PS VII significantly suppresses the viability, attachment, migration and invasive abilities of CRC cells in a concentration-dependent manner. In addition, PS Ⅶ reduced the expression levels and activity of matrix metalloproteinase (MMP)-2 and MMP-9. These data indicate that PS VII reduces the metastatic capability of CRC cells, possibly via the downregulation of the expression and activity of MMP-2 and MMP-9. These results demonstrate a novel therapeutic potential for PS VII in anti-metastatic therapy.

Abstract
BACKGROUND Thymoquinone (TQ), an active component of Nigella sativa or black cumin, elicits cytotoxic effects on various cancer cell lines. However, the anti-cancer effects of TQ on head and neck squamous cell carcinoma (HNSCC) remain unclear. METHODOLOGY/PRINCIPAL FINDINGS In this study, TQ elicited a strong cytotoxic effect on SASVO3, a highly malignant HNSCC cell line. The mechanisms of this cytotoxic effect were concentration dependent. TQ also induced apoptotic cell death in SASVO3 cells as indicated by an increase in Bax expression and caspase-9 activation. Apoptosis was possibly caspase-9 dependent because the exposure of cells to a caspase-9 inhibitor partially prevented cell death. The exposed cells also showed increased levels of autophagic vacuoles and LC3-II proteins, which are specific autophagy markers. Cell viability assay results further revealed that bafilomycin-A1, an autophagy inhibitor, enhanced TQ cytotoxicity; by comparison, Annexin V and propidium-iodide staining assay results showed that this inhibitor did not promote apoptosis. TQ treatment also increased the accumulation of autophagosomes. Using a lentivirus-shRNA system for LC3 silencing, we found that cell viability was eradicated in autophagy-defective cells. An in vivo BALB/c nude mouse xenograft model further showed that TQ administered by oral gavage reduced tumor growth via induced autophagy and apoptosis. CONCLUSIONS These findings indicated that TQ induced cell death in oral cancer cells via two distinct anti-neoplastic activities that can induce apoptosis and autophagy. Therefore, TQ is a promising candidate in phytochemical-based, mechanistic, and pathway-targeted cancer prevention strategies.

Abstract
Jujuboside B (1) is one of the saponins isolated from the seeds of Zizyphus jujuba var. spinosa, which are used as a well-known traditional medicine for the treatment of insomnia and anxiety in East Asian countries. This is the first study to investigate the antitumor mechanism of 1 in vivo and in vitro. The results showed that 1 induced apoptosis and autophagy in AGS and HCT 116 human cancer cells and also effectively suppressed tumor growth in a nude mouse xenograft model bearing HCT 116 cells. The apoptosis-inducing effect of 1 was characterized by annexin V/propidium iodide staining, sub-G1 phase increase, and caspase-3 activation. Mechanistic studies showed that 1-induced apoptosis is associated with the extrinsic pathway through an increase in FasL and caspase-8 activation. Moreover, 1 activated p38/c-Jun N-terminal kinase (JNK), and the extrinsic pathway-mediated apoptosis was attenuated by both SB202190 (a p38 inhibitor) and SP600125 (a JNK inhibitor). The autophagy-inducing effect was indicated by the formation of cytoplasmic vacuoles and microtubule-associated protein 1 light chain-3 II (LC3-II) conversion. The autophagy inhibitor bafilomycin A1 (BaF) decreased 1-induced cell viability and increased pp38, pJNK, FasL, caspase-8 activation, and caspase-3 activation. Taken together, these results demonstrate that 1 induced protective autophagy to retard extrinsic pathway-mediated apoptosis.

Abstract
Triterpenoid saponins are glycosides with remarkable structural and bioactive diversity. They are becoming increasingly significant in the treatment of cancer due to their efficacy and safety. This chapter provides an update on the sources, pharmacological effects, structure-activity relationships, and clinical studies of anticancer triterpenoid saponins with a particular focus on the molecular mechanisms underlying their therapeutic properties. The correlative references and study reports described were collected through PubMed. The anticancer triterpenoid saponins enable the inhibition of cancer formation and progression by modulating multiple signaling targets related to cellular proliferation, apoptosis, autophagy, metastasis, angiogenesis, inflammation, oxidative stress, multidrug resistance, cancer stem cells, and microRNAs. This review provides new insights into the molecular basis of triterpenoid saponins in the chemoprevention and chemotherapy of cancer.
