Eur J Pharmacol 2024; 972:176569. [PMID: 38593930 DOI: 10.1016/j.ejphar.2024.176569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 04/03/2024] [Accepted: 04/04/2024] [Indexed: 04/11/2024]
Abstract
In our previous study, we uncovered that ghrelin promotes angiogenesis in human umbilical vein endothelial cells (HUVECs) in vitro by activating the Jagged1/Notch2/VEGF pathway in preeclampsia (PE). However, the regulatory effects of ghrelin on placental dysfunction in PE are unclear. Therefore, we applied Normal pregnant Sprague-Dawley (SD) rats, treated with lipopolysaccharide (LPS), to establish a PE-like rat model. The hematoxylin-eosin (HE) staining method and immunohistochemistry (IHC) technology were used to detect morphological features of the placenta. IHC and Western blot were applied to examine Bax and Bcl-2 expression levels. The concentrations of serum soluble fms-like tyrosine kinase-1 (sFlt1) and placental growth factor (PIGF) were assessed by enzyme-linked immunosorbent assay (ELISA) kit. In addition, the apoptosis rates of JEG-3 and HTR-8/SVneo trophoblast cells were determined by Annexin V-FITC/PI apoptosis detection kit. Cell migratory capacities were assessed by scratch-wound assay, and RNA-sequencing assay was used to determine the mechanism of ghrelin in regulating trophoblast apoptosis. It has been found that ghrelin significantly reduced blood pressure, urinary protein, and urine creatinine in rats with PE, at the meanwhile, ameliorated placental and fetal injuries. Second, ghrelin clearly inhibited placental Bax expression and circulating sFlt-1 as well as elevated placental Bcl-2 expression and circulating PIGF, restored apoptosis and invasion deficiency of trophoblast cells caused by LPS in vitro. Finally, transcriptomics indicated that nuclear factor kappa B (NF-κB) was the potential downstream pathway of ghrelin. Our findings illustrated that ghrelin supplementation significantly improved LPS-induced PE-like symptoms and adverse pregnancy outcomes in rats by alleviating placental apoptosis and promoting trophoblast migration.

Chemical characterization of Callingcard Vine (Entada polystachya (L.) DC. var. polystachya) aqueous seed extract and evaluation of its cytotoxic, genotoxic and mutagenic properties. MUTATION RESEARCH. GENETIC TOXICOLOGY AND ENVIRONMENTAL MUTAGENESIS 2023; 891:503687.

Abstract
Callingcard Vine (Entada polystachya (L.) DC. var. polystachya - Fabaceae) is a common plant in coastal thickets from western Mexico through Central America to Colombia and Brazil, especially in Amazon biome. It has been popularly used as a urinary burning reliever and diuretic. However, the plant chemical constituents are poorly understood and Entada spp. genotoxic potential have not been previously investigated. In the present study we determined the chemical composition of the aqueous E. polystachya crude seed extract (EPCSE) and evaluated the cytotoxic, genotoxic and mutagenic properties of EPCSE in Salmonella typhimurium and Chinese hamster fibroblast (V79) cells. Cytotoxic activity was also evaluated in tumor cell lines (HT29, MCF7 and U87) and non-malignant cells (MRC5). The chemical analysis by High Resolution Mass Spectrometry (HRMS) of EPCSE indicated the presence of saponin and chalcone. The results of the MTT and clonal survival assays suggest that EPCSE is cytotoxic to V79 cells. Survival analysis showed higher IC50 in non-tumor compared with tumor cell lines. EPCSE showed induction of DNA strand breaks as revealed by the alkaline comet assay and micronucleus test. Using the modified comet assay, it was possible to detect the induction of oxidative DNA base damage by EPCSE in V79 cells. Consistently, the extract induced increase lipid peroxidation (TBARS), superoxide dismutase (SOD) and catalase (CAT) activities in V79 cells. In addition, EPCSE induced mutations in S. typhimurium TA98 and TA100 strains, confirming a mutagenic potential. Taken together, our results suggest that EPCSE is cytotoxic and genotoxic to V79 cells and mutagenic to S. typhimurium. These properties can be related to the pro-oxidant ability of the extract and induction of DNA lesions. Additionally, EPCSE could inhibit the growth of tumor cells, especially human colorectal adenocarcinoma (HT29) cell line, and can constitute a possible source of antitumor natural agents.

Abstract
Accumulating evidence attributes the role of aldose reductase (AR) in modulating ROS and inflammation which are the main factor responsible for cancer progression and drug resistance. Epalrestat is the only AR inhibitor being used in Asian countries. It did not make it to the markets of the USA and Europe due to marginal efficacy as an antioxidant and anti-inflammatory agent owing to difficulty reaching intracellular targets. In our previous studies, we attempted to synthesize the epalrestat analogs and reported that the compound 4-((Z)-5-((Z)-2-Cyano-3-phenylallylidene)-4-oxo-2-thioxothiazolidin-3-yl) benzoic acid named as NARI-29 has potent AR inhibition compared to epalrestat. In the current study, we aimed to find the effect of NARI-29 on ROS-induced cancer progression and TRAIL resistance in colon cancer in vitro models. In the first part of the study, we demonstrated that the NARI-29 has specific AKR1B1 inhibition and superior drug-like properties than epalrestat using bioinformatics tools. In the second part of the study, it was proven that NARI-29 has induced the hydrogen peroxide-triggered TRAIL-induced apoptosis in the colon cancer cells via modulating the AKR1B1/4HNE/FOXO3a/DR axis. The selective cytotoxicity of NARI-29 (10-fold) compared to epalrestat (4-fold) toward cancer cells is due to its differential ROS regulation and anti-inflammatory activities. Altogether, these data show that NARI-29 may be a potential candidate for AR inhibitors, which will be used to prevent colon cancer progression and as adjuvant therapy for preventing TRAIL resistance.

Funct Integr Genomics 2023; 23:109. [PMID: 36991225 DOI: 10.1007/s10142-023-01030-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Revised: 02/16/2023] [Accepted: 03/14/2023] [Indexed: 03/31/2023]
Abstract
Esophageal carcinoma (ESCA) is a common and lethal malignant tumor worldwide. The mitochondrial biomarkers were useful in finding significant prognostic gene modules associated with ESCA owing to the role of mitochondria in tumorigenesis and progression. In the present work, we obtained the transcriptome expression profiles and corresponding clinical information of ESCA from The Cancer Genome Atlas (TCGA) database. Differential expressed genes (DEGs) were overlapped with 2030 mitochondria-related genes to get mitochondria-related DEGs. The univariate cox regression, Least Absolute Shrinkage and Selection Operator (LASSO) regression, and multivariate cox regression were sequentially used to define the risk scoring model for mitochondria-related DEGs, and its prognostic value was verified in the external datasets GSE53624. Based on the risk score, ESCA patients were divided into high- and low-risk groups. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) were performed to further investigate the difference between low- and high-risk groups at the gene pathway level. CIBERSORT was used to evaluate immune cell infiltration. The mutation difference between high- and low-risk groups was compared by using the R package "Maftools". Cellminer was used to assess the association between the risk scoring model and drug sensitivity. As the most important outcome of the study, a 6-gene risk scoring model (APOOL, HIGD1A, MAOB, BCAP31, SLC44A2, and CHPT1) was constructed from 306 mitochondria-related DEGs. Pathways including the "hippo signaling pathway" and "cell-cell junction" were enriched in the DEGs between high and low groups. According to CIBERSORT, samples with high-risk scores demonstrated a higher abundance of CD4+ T cells, NK cells, M0 and M2 macrophages, and a lower abundance of M1 macrophages. The immune cell marker genes were correlated with the risk score. In mutation analysis, the mutation rate of TP53 was significantly different between the high- and low-risk groups. Drugs with a strong correlation with the risk model were selected. In conclusion, we focused on the role of mitochondria-related genes in cancer development and proposed a prognostic signature for individualized integrative assessment.

Abstract
As a medicinal herbal plant, Entada phaseoloides has high levels of secondary metabolites, particularly triterpenoid saponins, which are important resources for scientific research and medical applications. However, the lack of a reference genome for this genus has limited research on its evolution and utilization of its medicinal potential. In this study, we report a chromosome-scale genome assembly for E. phaseoloides using Illumina, Nanopore long reads, and high-throughput chromosome conformation capture technology. The assembled reference genome is 456.18 Mb (scaffold N50=30.9 Mb; contig N50=6.34 Mb) with 95.71 % of the sequences anchored onto 14 pseudochromosomes. E. phaseoloides was estimated to diverge from the Leguminosae lineage at approximately 72.0 million years ago. With the integration of transcriptomic and metabolomic data, gene expression patterns and metabolite profiling of E. phaseoloides were determined in different tissues. The pattern of gene expression and metabolic profile of the kernel were distinct from those of other tissues. Furthermore, the evolution of certain gene families involved in the biosynthesis of triterpenoid saponins and terpenes was analyzed and offer new insights into the formation of these two metabolites. Four CYP genes, one UGT gene and related transcription factors were identified as candidate genes contributing to regulation of triterpenoid saponins biosynthesis. As the first high-quality assembled reference genome in the genus Entada, it will not only provide new information for the evolutionary study of this genus and conservation biology of E. phaseoloides but also lay a foundation for the formation and utilization of secondary metabolites in medicinal plants.

Theasaponin E 1 Inhibits Platinum-Resistant Ovarian Cancer Cells through Activating Apoptosis and Suppressing Angiogenesis. Molecules 2021; 26:molecules26061681.

Abstract
Novel therapeutic strategies for ovarian cancer treatment are in critical need due to the chemoresistance and adverse side effects of platinum-based chemotherapy. Theasaponin E1 (TSE1) is an oleanane-type saponin from Camellia sinensis seeds. Its apoptosis-inducing, cell cycle arresting and antiangiogenesis activities against platinum-resistant ovarian cancer cells were elucidated in vitro and using the chicken chorioallantoic membrane (CAM) assay. The results showed that TSE1 had more potent cell growth inhibitory effects on ovarian cancer OVCAR-3 and A2780/CP70 cells than cisplatin and was lower in cytotoxicity to normal ovarian IOSE-364 cells. TSE1 significantly induced OVCAR-3 cell apoptosis via the intrinsic and extrinsic apoptotic pathways, slightly arresting cell cycle at the G2/M phase, and obviously inhibited OVCAR-3 cell migration and angiogenesis with reducing the protein secretion and expression of vascular endothelial growth factor (VEGF). Western bolt assay showed that Serine/threonine Kinase (Akt) signaling related proteins including Ataxia telangiectasia mutated kinase (ATM), Phosphatase and tensin homolog (PTEN), Akt, Mammalian target of rapamycin (mTOR), Ribosome S6 protein kinase (p70S6K) and e IF4E-binding protein 1(4E-BP1) were regulated, and Hypoxia inducible factor-1α (HIF-1α) protein expression was decreased by TSE1 in OVCAR-3 cells. Moreover, TSE1 treatment potently downregulated protein expression of the Notch ligands including Delta-like protein 4 (Dll4) and Jagged1, and reduced the protein level of the intracellular domain (NICD) of Notch1. Combination treatment of TSE1 with the Notch1 signaling inhibitor tert-butyl (2S)-2-[[(2S)-2-[[2-(3,5-difluorophenyl)acetyl]amino]propanoyl]amino]-2-phenylacetate (DAPT), or the Akt signaling inhibitor wortmannin, showed a stronger inhibition toward HIF-1α activation compared with single compound treatment. Taken together, TSE1 might be a potential candidate compound for improving platinum-resistant ovarian cancer treatment via Dll4/Jagged1-Notch1-Akt-HIF-1α axis.

Abstract
Reactive oxygen species (ROS), an important molecule inducing oxidative stress in organisms, play a key role in tumorigenesis, tumor progression and recurrence. Recent findings on ROS have shown that ROS can be used to treat cancer as they accelerate the death of tumor cells. At present, pro-oxidant drugs that are intended to increase ROS levels of the tumor cells have been widely used in the clinic. However, ROS are a double-edged sword in the treatment of tumors. High levels of ROS induce not only the death of tumor cells but also oxidative damage to normal cells, especially bone marrow hemopoietic cells, which leads to bone marrow suppression and (or) other side effects, weak efficacy of tumor treatment and even threatening patients' life. How to enhance the killing effect of ROS on tumor cells while avoiding oxidative damage to the normal cells has become an urgent issue. This study is a review of the latest progress in the role of ROS-mediated programmed death in tumor treatment and prevention and treatment of oxidative damage in bone marrow induced by ROS.

Abstract
Kurarinone, a flavonoid isolated from Sophora flavescens Aiton, has been reported to have significant antitumor activity. However, the cytotoxic activity of kurarinone against non-small cell lung cancer (NSCLC) cells is still under explored. In our study, we have evaluated the inhibitory effects of kurarinone on the growth of NSCLC both in vivo and in vitro as well as the molecular mechanisms underlying kurarinone-induced A549 cell apoptosis. The results showed that kurarinone effectively inhibited the proliferation of A549 cells with little toxic effects on human bronchial epithelial cell line BEAS-2B. FASC examination and Hoechst 33258 staining assay showed that kurarinone dose-dependently provoked A549 cells apoptosis. Mechanistically, kurarinone significantly decreased the ratio of Bcl-2/Bax, thereby causing the activation of caspase 9 and caspase 3, and reduced the expression of Grp78, which led to relieve the inhibition of caspase-12 and caspase-7, as well as suppressing the activity of AKT. Meanwhile, modeling results from the Surflex-Dock program suggested that residue Ser473 of Akt is a potential binding site for kurarinone. In vivo, kurarinone inhibited the growth of A549 xenograft mouse models without apparent signs of toxicity. Our study indicated that kurarinone has the potential effects of anti-NSCLC, implemented through activating mitochondria apoptosis signaling pathway, as well as repressing the activity of endoplasmic reticulum pathway and AKT in A549 cells.

Abstract
Natural plants offer a treasure trove of resources for anticancer drug development. Clematis are widely used in Traditional Chinese Medicine. However, studies on the active substances in Clematis are scarce. In the present study, four monomer compounds were successfully extracted from this species and their inhibitory effects on the growth of breast cancer cells were investigated using bioactivity tests. Among them, Clematis hederagenin saponin (CHS) belongs to the class of triterpenoid saponins. CHS showed cytotoxic effects on breast cancer cells in a dose- and time-dependent manner. The compound also induced apoptosis in breast cancer cells in a time-dependent manner. Further investigation into the underlying mechanisms of apoptosis induction in breast cancer cells showed that the compound significantly reduced mitochondrial Apaf-1 and cytochrome c proteins in breast cancer cells. In addition, it upregulated the activities of caspase-3 and −9. In conclusion, CHS induced apoptosis in breast cancer cells through regulation of the mitochondrial apoptosis pathway. The results suggest that the hederagenin saponin extracted from Clematis ganpiniana offers great potential as a novel anti-breast cancer drug.

Anticancer Effects of Sinocrassulosides VI/VII from Silene viscidula on HeLa Cells. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 2017:8240820. [PMID: 28769987 PMCID: PMC5523537 DOI: 10.1155/2017/8240820] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/12/2017] [Accepted: 03/23/2017] [Indexed: 12/31/2022]
Abstract
Natural products are becoming increasingly important in chemoprevention and for cancer therapy. Silene viscidula (S. viscidula), a traditional Chinese herb, has long been used as an anti-inflammatory and neuroleptic agent. However, the anticancer activity of S. viscidula has remained unclear. In this study, 16 compounds were extracted from S. viscidula. Among those compounds, sinocrassulosides VI/VII, an inseparable isomer mixture, possess the strongest inhibitory activity on HeLa cells with the IC50 value of 2.37 μM. Mechanism studies found that sinocrassulosides VI/VII downregulated the expression of cyclin D1 and decreased retinoblastoma (Rb) phosphorylation, which arrested HeLa cells in the G1 phase. Also, sinocrassulosides VI/VII could induce senescence via the upregulation of p16 and a significant increase of β-galactosidase (β-gal) staining. Our results suggest that sinocrassulosides VI/VII may be a new therapeutic potential agent for cervical cancer. In addition, we explored the structure-activity relationships of three groups of the configurational isomer with similar chemical structure from S. viscidula. We first demonstrated that the length of the ester chains linked to the carboxyl group of the glucuronic acid residue could affect the potent cytotoxicity. This finding will open new avenues for developing effective anticancer compounds by modifying the components derived from plants in nature.

Abstract
The use of natural products derived from plants as medicines precedes even the recorded human history. In the past few years there were renewed interests in developing natural compounds and understanding their target specificity for drug development for many devastating human diseases. This has been possible due to remarkable advancements in the development of sensitive chemistry and biology tools. Sanguinarine is a benzophenanthridine alkaloid derived from rhizomes of the plant species Sanguinaria canadensis. The alkaloid can exist in the cationic iminium and neutral alkanolamine forms. Sanguinarine is an excellent DNA and RNA intercalator where only the iminium ion binds. Both forms of the alkaloid, however, shows binding to functional proteins like serum albumins, lysozyme and hemoglobin. The molecule is endowed with remarkable biological activities and large number of studies on its various activities has been published potentiating its development as a therapeutic agent particularly for chronic human diseases like cancer, asthma, etc. In this article, we review the properties of this natural alkaloid, and its diverse medicinal applications in relation to how it modulates cell death signaling pathways and induce apoptosis through different ways, its utility as a therapeutic agent for chronic diseases and its biological effects in animal and human models. These data may be useful to understand the therapeutic potential of this important and highly abundant alkaloid that may aid in the development of sanguinarine-based therapeutic agents with high efficacy and specificity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The seed of Entada phaseoloides (L.) Merr. (Entada phaseoloides) has been long used as a folk medicine for the treatment of Diabetes mellitus by Chinese ethnic minorities. Recent reports have demonstrated that total saponins from Entada phaseoloides (TSEP) could reduce fasting blood glucose in type 2 diabetic rats. However, the mechanism has not been fully elucidated. The aim of this study was to explore the underlying mechanisms of TSEP on type 2 Diabetes mellitus (T2DM). MATERIALS AND METHODS Primary mouse hepatocytes and HepG2 cells were used to investigate the effects of TSEP on gluconeogenesis. After treatment with TSEP, glucose production, genes expression levels of Glucose-6-phosphatase (G6pase) and Phosphoenoylpyruvate carboxykinase (Pepck) were detected. The efficacy and underlying mechanism of TSEP on AMP-activated protein kinase (AMPK) signaling pathway were determinated. RESULTS TSEP significantly inhibited glucose production and the gluconeogenic gene expression. Treatment with TSEP elevated the phosphorylation of AMPK, which in turn promoted the phosphorylation of acetyl coenzyme A (ACC) and Akt/glycogen synthase kinase 3β (GSK3β), respectively. Furthermore, TSEP reduced lipid accumulation and improved insulin sensitivity in hepatocytes. CONCLUSION These findings provide evidence that TSEP exerts an antidiabetic effect by suppressing hepatic gluconeogenesis via the AMPK signaling pathway.

Abstract
Asterothamnus centrali-asiaticus, a kind of characteristic shrub abundant in grassland and desert areas, has been used as forage fodder for camels and goats in Central Asia, and this plant also plays a critical role in the maintenance of desert grassland ecosystems as a result of its tolerance to poor soils and sand burial. However, its chemical composition has been rarely reported. In this study, phytochemical investigation of this pasturage was performed and three new triterpenoid saponins (1-3) were isolated together with nine known triterpenoid saponins (4-12) using preparative two-dimensional reversed-phase liquid chromatography/hydrophilic interaction chromatography (2D RPLC/HILIC). Their structures were elucidated via diverse spectroscopic analyses, including infrared (IR) spectrometry, high-resolution electrospray ionization mass spectrometry (HR-ESIMS), and one-dimensional (1D) and 2D nuclear magnetic resonance (NMR). All isolated triterpenoid saponins (1-12) were reported from this genus for the first time, and they were further evaluated for their cytotoxicity against four cancer cell lines (A549, HepG2, MGC-803, and MFC), which indicated that compound 11 showed potent cytotoxicity against the HepG2 cell line, with an IC50 value of 6.85 μg/mL.

Abstract
The induced-apoptosis effect and mechanism of human esophageal cancer Ec-109 cells via tanshinone IIA was investigated. The Ec-109 cells were cultured in vitro with different concentrations of tanshinone IIA (2 μg/mL, 4 μg/mL, or 8 μg/mL) for 12, 24, 36, and 48 hours. MTT assay was used to evaluate the proliferative inhibition rate of tanshinone IIA on esophageal Ec-109 cells. After 24 hours of culturing in vitro, a control group was assigned. The apoptosis rate was detected by the AO/EB and annexin V-FITC/propidium iodide assay, and the protein levels of Caspase-4 and CHOP were determined by the Western blot technique. MTT data showed that tanshinone IIA could significantly inhibit the proliferation of Ec-109 cells with a dose- and time- dependent mode. Compared with the control group, tanshinone IIA could apparently induce apoptosis of Ec-109 cells, and the level of Caspase-4 and CHOP ( p<0.01) obviously increased. Tanshinone IIA can significantly induce the apoptosis of Ec-109 cells, which may take effect by the stress pathway of the endoplasmic reticulum.

Abstract
The phytochemical investigation of the ethanol extract from the stems of Entada phaseoloides (L.) Merr (also called "Guo Gang Long") led to the isolation of eleven triterpene saponins (1-11). Their structures were elucidated by extensive spectroscopic methods including 1D- ((1)H and (13)C) and 2D-NMR ((1)H-(1)H COSY, HSQC, HMBC, HSQC-TOCSY and ROESY) experiments as well as ESIMS analysis and hydrolysis. These saponins comprised entagenic acid as the main aglycon, saccharide moieties at C-3 and C-28, and esterification of C-2 or C-3 hydroxyl group of the terminal β-d-glucopyranose unit with a monoterpenic acid. To further explain the clinical applications of "Guo Gang Long" for its anti-inflammatory effect, the inhibitory activities on the production of NO of the saponins and the related aglycon, entagenic acid (12), were evaluated in vitro. The compounds containing a free hydroxyl at C-3 of aglycon (1 and 4) and entagenic acid showed significant activities against NO production in lipopolysaccharide-stimulated mouse macrophage RAW264.7 cells with IC50 values of 25.08, 20.13 and 23.48 μM, respectively. And the three compounds could also inhibit the release of pro-inflammatory cytokines, such as TNF-α, IL-1β, IL-6 and IL-8.

Abstract
INTRODUCTION Caspase-9 is the apoptotic initiator protease of the intrinsic or mitochondrial apoptotic pathway, which is activated at multi-protein activation platforms. Its activation is believed to involve homo-dimerization of the monomeric zymogens. It binds to the apoptosome to retain substantial catalytic activity. Variety of apoptotic stimuli can regulate caspase-9. However, the mechanism of action of various regulators of caspase-9 has not been summarized and compared yet. In this article, we elucidate the regulators of caspase-9 including microRNAs, natural compounds that are related to caspase-9 and ongoing clinical trials with caspase-9 to better understand the caspase-9 in suppressing cancer. AREAS COVERED In this study, the basic mechanism of apoptosis pathways, regulators of caspase-9 and the development of drugs to regulate caspase-9 are reviewed. Also, ongoing clinical trials for caspase-9 are discussed. EXPERT OPINION Apoptosis has crucial role in cancer, brain disease, aging and heart disease to name a few. Since caspase-9 is an initiator caspase of apoptosis, it is an important therapeutic target of various diseases related to apoptosis. Therefore, a deep understanding on the roles as well as regulators of caspase-9 is required to find more effective ways to conquer apoptosis-related diseases especially cancer.

Abstract
Natural plant products occupy a very important position in the area of cancer chemotherapy. Many triterpenoid saponins have been proved as potential agents for chemoprevention and therapy of breast cancer. α-hederin, a monodesmosidic triterpenoid saponin distributed in Hedera or Nigella species, displays many biological activities. It is increasingly investigated for its promising anticancer potential since it has been shown to have cytotoxicity against several types of cancer cells. However, studies of α-hederin on breast cancer are limited, most of which focus on biological activity, while the mechanisms have not been widely reported yet. Previously, we purified and identified α-hederin from Clematis ganpiniana, a herb used in traditional Chinese medicine with antitumor action. In the present study, α-hederin showed strong inhibitory activity on the growth of breast cancer cells and induced apoptosis in these cells. α-hederin induced depolarization of mitochondrial membrane potential which released Apaf-1 and cytochrome c from the intermembrane space into the cytosol, where they promoted caspase-3 and caspase-9 activation. This is the first report on the growth inhibition and pro-apoptotic effects of α-hederin on breast cancer cells and the relative apoptosis pathways. It implied that triterpenoid saponin α-hederin could be a promising candidate for chemotherapy of breast cancer.

Abstract
There is growing interest in development of natural products as anti-cancer and chemopreventive agents. Many triterpenoids have been proved as potential agents for chemoprevention and therapy of breast cancer. Ginsenosides from ginseng, which mostly belong to dammarane-type triterpenoids, have gained great attention for their anti-breast cancer activity with diverse mechanisms. However, studies of other kinds of triterpenoid saponins on breast cancer are limited. Previously, we purified and identified a novel oleanane-type triterpene saponin named D Rhamnose β-hederin (DRβ-H) from Clematis ganpiniana, a Chinese traditional anti-tumor herb. In the present study, DRβ-H showed strong inhibitory activity on the growth of various breast cancer cells and induced apoptosis in these cells. DRβ-H inhibited PI3K/AKT and activated ERK signaling pathway. PI3K inhibitor LY294002 synergistically enhanced DRβ-H-induced apoptosis whereas MEK inhibitor U0126 reduced the apoptosis rate. Moreover, DRβ-H regulated the ratio of pro-apoptotic and anti-apoptotic Bcl-2 family proteins. Furthermore, DRβ-H induced depolarization of mitochondrial membrane potential which released Apaf-1 and Cytochrome C from the inter membrane space into the cytosol, where they promoted caspase-9 and caspase-3 activation. This is the first report on the pro-apoptotic effects of DRβ-H, a novel oleanane-type triterpenoid saponin, on breast cancer cells and its comprehensive apoptosis pathways. It implied that oleanane-type triterpenoid saponin DRβ-H could be a promising candidate for chemotherapy of breast cancer.

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.
