Abstract
Cancer metastasis is the leading cause of death in cancer patients. Due to the limitations of conventional cancer treatment, such as chemotherapy, there is a need for novel therapeutics to prevent metastasis. Ginsenoside Rg3, a major active component of Panax ginseng C.A. Meyer, inhibits tumor growth and has the potential to prevent tumor metastasis. Herein, we systematically reviewed the anti-metastatic effects of Rg3 from experimental studies. We searched for articles in three research databases, MEDLINE (PubMed), EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) through March 2022. In total, 14 studies (eight animal and six in vitro) provide data on the anti-metastatic effects of Rg3 and the relevant mechanisms. The major anti-metastatic mechanisms of Rg3 involve cancer stemness, epithelial mesenchymal transition (EMT) behavior, and angiogenesis. Taken together, Rg3 would be one of the herbal resources in anti-metastatic drug developments through further well-designed investigations and clinical studies. Our review provides valuable reference data for Rg3-derived studies targeting tumor metastasis.

Exploration and Characterization of Novel Glycoside Hydrolases from the Whole Genome of Lactobacillus ginsenosidimutans and Enriched Production of Minor Ginsenoside Rg3( S) by a Recombinant Enzymatic Process. Biomolecules 2020; 10:biom10020288. [PMID: 32059542 PMCID: PMC7072194 DOI: 10.3390/biom10020288] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2019] [Revised: 01/29/2020] [Accepted: 02/07/2020] [Indexed: 12/16/2022] Open
Abstract
Background: Several studies have reported that ginsenoside Rg3(S) is effective in treating metastatic diseases, obesity, and various cancers, however, its presence in white ginseng cannot be estimated, and only a limited amount is present in red ginseng. Therefore, the use of recombinant glycosidases from a Generally Recognized As Safe (GRAS) host strain is a promising approach to enhance production of Rg3(S), which may improve nutritional activity, human health, and quality of life. Method: Lactobacillus ginsenosidimutans EMML 3041T, which was isolated from Korean fermented pickle (kimchi), presents ginsenoside-converting abilities. The strain was used to enrich the production of Rg3(S) by fermenting protopanaxadiol (PPD)-mix-type major ginsenosides (Rb1, Rb2, Rc, and Rd) in four different types of food-grade media (1, MRS; 2, Basel Food-Grade medium; 3, Basel Food-Grade medium-I, and 4, Basel Food-Grade medium-II). Due to its tendency to produce Rg3(S), the presence of glycoside hydrolase in Lactobacillus ginsenosidimutans was proposed, the whole genome was sequenced, and the probable glycoside hydrolase gene for ginsenoside conversion was cloned. Results: The L. ginsenosidimutans EMML 3041T strain was whole genome sequenced to identify the target genes. After genome sequencing, 12 sets of glycoside hydrolases were identified, of which seven sets (α,β-glucosidase and α,β-galactosidase) were cloned in Escherichia coli BL21 (DE3) using the pGEX4T-1 vector system. Among the sets of clones, only one clone (BglL.gin-952) showed ginsenoside-transforming abilities. The recombinant BglL.gin-952 comprised 952 amino acid residues and belonged to glycoside hydrolase family 3. The enzyme exhibited optimal activity at 55 °C and a pH of 7.5 and showed a promising conversion ability of major ginsenoside Rb1→Rd→Rg3(S). The recombinant enzyme (GST-BglL.gin-952) was used to mass produce Rg3(S) from major ginsenoside Rb1. Scale-up of production using 50 g of Rb1 resulted in 30 g of Rg3(S) with 74.3% chromatography purity. Conclusion: Our preliminary data demonstrated that this enzyme would be beneficial in the preparation of pharmacologically active minor ginsenoside Rg3(S) in the functional food and pharmaceutical industries.

Abstract
Background: Rectal polyps is a major risk factor for rectal cancer. There is a need to explore a panel of preventive measures, as well as reliable biomarkers for screening of rectal polyps. Patients and methods: We conducted a case control study which aimed to explore the effects of regular consumption of ginsenoside Rg3, profiling of selected cytokines, and development of rectal polyps in a Chinese population. Results: Significantly higher levels of IL-4, MIP-1β, FasL, TGF-β1, and RANTES were detected in rectal polyp cases. Further, we found significant dose-response relationships between quartile-categorized levels of IL-4, MIP-1β, FasL, and TGF-β1, and risk of rectal polyps. The strongest associations for IL-4, MIP-1β, FasL, and TGF-β1 were observed for the highest quartile vs the lowest quartile with an OR of 1.78, 2.70, 1.49, and 2.36, respectively. Compared with non-Rg3 consumers, regular Rg3 consumers had a significantly lower risk of rectal polyps (OR =0.71; 95% CI: 0.55–0.92; P=0.009). We also found that Rg3 consumers had significantly lower levels of IL-4, MIP-1β, FasL, and TGF-β1 than non-Rg3 consumers, in both rectal polyp cases and healthy controls. Conclusion: These results indicate that regular consumption of Rg3 might prevent the occurrence of rectal polyps through decreasing the serum level of selected cytokines, including IL-4, MIP-1β, FasL, and TGF-β1. Further clinical trials and prospective cohort studies with larger sample sizes are warranted to validate the anti-inflammatory activity and the anti-tumorigenic role of Rg3.

Abstract
Aims and Background Tanshinone II-A is an alcohol extract of the root of the traditional Chinese medicinal plant Salvia miltiorrhiza Bunge, whose effects and mechanism in tumor metastasis are still unclear. The aim of this study was to investigate the effects of tanshinone II-A on tumor invasion and metastasis in human hepatocellular carcinoma (HCC) and its possible mechanism of action. Methods and Study Design The HCC cell lines HepG2 and SMMC-7721 were treated with tanshinone II-A at different doses. Invasion and metastasis of tumor cells were examined by in vitro and in vivo assays. The molecular mechanisms of tanshinone II-A for inhibiting invasion and metastasis of HCC cells were investigated by Western blot and gelatin zymography. Results Treatment with tanshinone II-A had inhibitory effects on the migration and invasion of HCC cells. Increasing doses resulted in enhanced inhibitory effects. At 0.5 mg/L, the inhibitory effect was noticeable. At 1 mg/L, the inhibitory rate was 53.15%. The inhibitory effect became stronger with time; among 24, 48, 72 and 96 hours of treatment, the most significant effects were observed at 72 hours. Tanshinone II-A also significantly inhibited in vivo metastasis of HepG2 cells. Tanshinone II-A inhibited in vitro and in vivo invasion and metastasis of HCC cells by reducing the expression of the metalloproteinases MMP2 and MMP9 and by blocking NF-kappa B activation. Conclusions Tanshinone II-A effectively inhibited invasion and metastasis of HCC cells in vitro and in vivo, partly by inhibiting the activity of MMP2 and MMP9, and partly via the NF-kappa B signal transduction pathway.

Abstract
In today's world of modern medicine and novel therapies, cancer still remains to be one of the prime contributor to the death of people worldwide. The modern therapies improve condition of cancer patients and are effective in early stages of cancer but the advanced metastasized stage of cancer remains untreatable. Also most of the cancer therapies are expensive and are associated with adverse side effects. Thus, considering the current status of cancer treatment there is scope to search for efficient therapies which are cost-effective and are associated with lesser and milder side effects. Phytochemicals have been utilized for many decades to prevent and cure various ailments and current evidences indicate use of phytochemicals as an effective treatment for cancer. Hyperactivation of phosphoinositide 3-kinase (PI3K) signaling cascades is a common phenomenon in most types of cancers. Thus, natural substances targeting PI3K pathway can be of great therapeutic potential in the treatment of cancer patients. This chapter summarizes the updated research on plant-derived substances targeting PI3K pathway and the current status of their preclinical studies and clinical trials.

Abstract
This study investigates the anti-angiogenic effect of 3β, 12β, 20(S)-trihydroxy dammarane-3-O-β-d-glucopyranosyl(1-2)-β-d-glucopyranoside(HRG), a new chemical compound obtained by structure modification on Ginseng saponins Rg3, associated with the regulation of matrix metalloproteinases(MMPs) and its upstream signal-regulated molecule of vascular endothelial growth factor(VEGF) and basic fibroblast growth factor(b-FGF) in vitro, which plays an critical role in angiogenesis during the process of carcinoma. In our study, to investigate the anti-angiogenesis effect of HRG in HUVECs, we utilized cell proliferation assay, tube formation assay, wound-healing assay, Semi-quantitative reverse transcription PCR, and Western blot assay. Our results demonstrated that HRG plays a major role in the regulation of proliferation, migration and tube formation of HUVECs by suppressing the expression of VEGF and b-FGF in both transcriptional and post-transcriptional levels. In addition, the expression of MMP-2 and MMP-9, which were related to the ECM degradation, were down-regulated after administration of HRG as well. Overall, our results revealed that HRG strongly inhibited the process of angiogenesis and shows better effectiveness than Rg3.

Abstract
The purpose of this case report is to show the potential benefit of Korean medicine therapy for treating multiple metastatic breast cancer. A 45-year-old Korean woman was diagnosed with right breast invasive ductal carcinoma in August 2012 but did not receive any treatment until October 2015 when she was diagnosed with stage 4 right breast cancer with multiple liver, bone, mesentery, retroperitoneum, and axillary lymph node metastases. After chemo-port insertion, she was treated with palliative chemotherapy and the first line of trastuzumab and paclitaxel, and the port was removed due to port infection. To treat sepsis, vancomycin and tazoperan were administered, before the third line of trastuzumab and paclitaxel was carried out. However, the patient gave up chemotherapy due to vancomycin-resistant enterococci and general weakness. Later, she received Korean medicine therapy with wild ginseng pharmacopuncture, distilled Soramdan S, Hae, and Jeobgoldan for 8 months, which led to a significant decrease of the multiple metastases. The patient was able to start walking again with the help of a walking stick. However, a new metastatic lesion was found on the right adrenal gland. This case suggests that the combination of chemotherapy and Korean medicine therapy may be valuable. Further research is indicated.

Ginsenoside 20(S)-Rh2 exerts anti-cancer activity through targeting IL-6-induced JAK2/STAT3 pathway in human colorectal cancer cells. JOURNAL OF ETHNOPHARMACOLOGY 2016; 194:83-90. [PMID: 27566200 DOI: 10.1016/j.jep.2016.08.039] [Citation(s) in RCA: 64] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/02/2016] [Revised: 08/16/2016] [Accepted: 08/22/2016] [Indexed: 05/21/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Panax ginseng is one of the most well-known medicinal herbs in Korea and China, which has been used for treatment and prevention of cancer, obesity, diabetes, and cardiovascular diseases. Ginsenosides are the major components of P. ginseng, having a wide range of pharmacological activities. Among the ginsenosides, protopanaxadiol (PPD)-types reportedly have potent anti-cancer effects. Rh2 is PPD-type ginsenoside, and two stereoisomeric forms of Rh2 as 20(S)- and 20(R)-Rh2 were selectively isolated recently. AIM OF THE STUDY The biological activities of Rh2 ginsenosides are known to depend on their differences in stereochemistry. Colorectal cancer (CRC) is one of the most lethal neoplasm, and cancer-related death is usually associated with metastasis to other organs. We aimed this study to investigate whether 20(S)- and 20(R)-Rh2 can suppress tumor invasion in human CRC cells. MATERIALS AND METHODS 20(S)- and 20(R)-Rh2 were isolated from the roots of ginseng. Human CRC cells were incubated with 20(S)- or 20(R)-Rh2 in the presence or absence of interleukin-6. An MTT assay was used to measure cell viability. Western blot and quantitative real-time PCR analyses were performed to determine levels of expression and phosphorylation. An invasion assay was performed using a Boyden chamber system with the Matrigel-coated membrane to measure cancer cell invasion. RESULTS 20(S)- and 20(R)-Rh2 showed differential cytotoxic activity. Only 20(S)-Rh2 decreased cancer cell viability. Additionally, 20(S)-Rh2 effectively inhibited IL-6-induced signal transducer and activator of transcription 3 (STAT3) phosphorylation and the expression of matrix metalloproteinases (MMPs), including MMP-1, -2, and -9, resulting in inhibition of cancer cell invasion. Interestingly, these pharmacological activities of 20(S)-Rh2 were more potent than those of 20(R)-Rh2. Furthermore, combination treatment showed that 20(S)-Rh2 enhanced the sensitization of doxorubicin-treated anti-cancer activities in CRC cells. CONCLUSION Our results demonstrated that ginsenoside 20(S)-Rh2 has therapeutic potential for the treatment with CRC and may be valuable as a combination partner with more classic chemotherapeutic agents, such as doxorubicin, to treat CRC.

Abstract
Leukemia is currently one of the most deadly diseases. Ginseng has been used in Asian countries for the treatment and prevention of various diseases, including leukemia, but the molecular mechanism of its antileukemia activity has not been well defined. The aim of this study was to explore the effect of 20-(s)-ginsenoside Rg3 on apoptosis in human leukemic U937 and HL-60 cells and the underlying mechanism. We found that 20-(s)-ginsenoside Rg3 reduced cell viability and induced apoptosis in U937 and HL-60 cells. The induction of apoptosis was accompanied by the downregulation of PI3K/Akt family proteins. Moreover, we observed that 20-(s)-ginsenoside Rg3 treatment resulted in activation of caspase-3 and caspase-9. Taken together, our findings suggest for the first time that 20-(s)-ginsenoside Rg3 can promote apoptosis in U937 and HL-60 cells, at least partly through the downregulation of PI3K/Akt family proteins. Moreover, the triggering of caspase-3 and caspase-9 activation mediated apoptotic induction. All these findings collectively demonstrate that the natural compound 20-(s)-ginsenoside Rg3 effectively induces apoptosis in human leukemic cells, which suggests that this compound may play a role in future therapies for leukemia.

Abstract
As with many other hydrophobic anticancer agents, 20(S)-protopanaxadiol (PPD) has a very low oral bioavailability. In this study, a precipitation-combined ultrasonication technique was used to prepare PPD nanosuspensions. The mean particle size of the nanosuspensions was approximately 222 ± 12 nm, the drug payload achieved 50% after lyophilization and the maximum PPD concentration can reach 100 mg/ml, which is over 30 000 times the solubility of PPD in aqueous solution (3 μg/ml). After oral administration, the Cmax and AUClast values of PPD nanosuspensions were approximately 3.66-fold and 3.48-fold as those of PPD coarse suspensions, respectively. In contrast to the free drug solution, PPD nanosuspensions showed higher in vitro anti-tumor activity against HepG-2 cells (an IC50 value of 1.40 versus 5.83 μg/ml at 24 h, p < 0.01). The in vivo study in H22-tumor-bearing mice demonstrated that PPD nanosuspensions showed good anti-tumor efficacy with an inhibition rate of 79.47% at 100 mg/kg, while 50 mg/kg of cyclophosphamide was displayed as positive control, and the inhibition rate was 87.81%. Considering the highest drug payload, oral bioavailability reported so far, significant anti-tumor efficacy and excellent safety of encapsulated drugs, PPD nanosuspensions could be used in potential effective strategies for anticancer therapy; further investigation is ongoing.

Abstract
Colorectal cancer is one of the most prevalent diseases all over the world. Early screening and start of chemotherapy is effective in decreasing mortality. This type of cancer can be controlled to some extent via a healthy diet rich in fruit and vegetables. Ginseng is a plant which has been consumed as a herbal medicine for thousands of years in Asian countries. Several in vitro and in vivo studies have shown that this plant not only reduces the incidence of colorectal cancer, but also improves patient's status by enhancing the effects of chemotherapy drugs. However, further studies are needed to prove this relationship. We briefly review ginseng and its components such as ginsenosides reported anticancer effects and their mechanisms of action. Understanding these relationships may produce insights into chemical and pharmacological approaches for enhancing the chemo preventive effects of ginsenosides and for developing novel anticancer agents.

Abstract
To elucidate the function of mevalonate-5-pyrophosphate decarboxylase (MVD) and farnesyl pyrophosphate synthase (FPS) in triterpene biosynthesis, the genes governing the expression of these enzymes were transformed into Panax ginseng hairy roots. All the transgenic lines showed higher expression levels of PgMVD and PgFPS than that by the wild-type control. Among the hairy root lines transformed with PgMVD, M18 showed the highest level of transcription compared to the control (14.5-fold higher). Transcriptions of F11 and F20 transformed with PgFPS showed 11.1-fold higher level compared with control. In triterpene analysis, M25 of PgMVD produced 4.4-fold higher stigmasterol content (138.95 μg/100 mg, dry weight [DW]) than that by the control; F17 of PgFPS showed the highest total ginsenoside (36.42 mg/g DW) content, which was 2.4-fold higher compared with control. Our results indicate that metabolic engineering in P. ginseng was successfully achieved through Agrobacterium rhizogenes-mediated transformation and that the accumulation of phytosterols and ginsenosides was enhanced by introducing the PgMVD and PgFPS genes into the hairy roots of the plant. Our results suggest that PgMVD and PgFPS play an important role in the triterpene biosynthesis of P. ginseng.

Abstract
This case report is aimed to investigate the effects of Korean medicine therapy (KMT) including oral herbal medicine and herb nebulizer therapy in treating metastatic bladder cancer in the lungs. A 74-year-old man was diagnosed with metastatic bladder cancer in both lungs in August 2013. He refused any chemotherapy and was admitted to our hospital in a much progressed state on January 11, 2014. Since then, he was treated with KMT until May 17, 2014. The main oral herbal medicines were Hyunamdan made of heat-processed ginseng, Hangamdan S made of Cordyceps militaris, Panax ginseng radix, Commiphora myrrha, calculus bovis, margarita, Boswellia carteri, Panax notoginseng radix and Cremastra appendiculata tuber, and nebulizer therapy with Soram nebulizer solution made of wild ginseng and Cordyceps sinensis distillate. Their effect was evaluated considering the change of the main symptoms and using serial chest X-ray. The size and number of multiple metastatic nodules in both lungs were markedly decreased and the symptoms had disappeared. These results suggest that KMT can be an effective method to treat metastatic bladder cancer in the lungs.

Abstract
Ginsenosides, extracted from the traditional Chinese herb ginseng, are a series of novel natural anticancer products known for their favorable safety and efficacy profiles. The present study aimed to investigate the cytotoxicity of ginsenoside Rf to human osteosarcoma cells and to explore the anticancer molecular mechanisms of ginsenoside Rf. Five human osteosarcoma cell lines (MG-63, OS732, U-2OS, HOS and SAOS-2) were employed to investigate the cytotoxicity of ginsenoside Rf by MTT and colony forming assays. After treatment with ginsenoside Rf, MG-63 cells which were the most sensitive to ginsenoside Rf, were subjected to flow cytometry to detect cell cycle distribution and apoptosis, and nuclear morphological changes were visualized by Hoechst 33258 staining. Caspase-3, -8 and -9 activities were also evaluated. The expression of cell cycle markers including cyclin B1 and Cdk1 was detected by RT-PCR and western blotting. The expression of apoptotic genes Bcl-2 and Bax and the release of cytochrome c were also examined by western blotting. Change in the mitochondrial membrane potential was observed by JC-1 staining in situ. Our results demonstrated that the cytotoxicity of ginsenoside Rf to these human osteosarcoma cell lines was dose-dependent, and the MG-63 cells were the most sensitive to exposure to ginsenoside Rf. Additionally, ginsenoside Rf induced G2/M phase cell cycle arrest and apoptosis in MG-63 cells. Furthermore, we observed upregulation of Bax and downregulation of Bcl-2, Cdk1 and cyclin B1, the activation of caspase-3 and -9 and the release of cytochrome c in MG-63 cells following treatment with ginsenoside Rf. Our findings demonstrated that ginsenoside Rf induces G2/M phase cell cycle arrest and apoptosis in human osteosarcoma MG-63 cells through the mitochondrial pathway, suggesting that ginsenoside Rf, as an effective natural product, may have a therapeutic effect on human osteosarcoma.

Abstract
Cancer still imposes a global threat to public health. After decades of research on cancer biology and enormous efforts in developing anticancer therapies, we now understand that the majority of cancers can be prevented. Bioactive phytochemicals present in edible plants have been shown to reduce the risk of various types of cancer. Ginseng (Panax ginseng C.A. Meyer), which contains a wide variety of saponins, known as ginsenosides, is an age-old remedy for human ailments, including cancer. Numerous laboratory-based studies have revealed the anticancer properties of ginsenosides, which compel tumor cells to commit suicide, arrest the proliferation of cancer cells in culture and inhibit experimentally-induced tumor formation in laboratory animals. Ginsenosides have been reported to inhibit tumor angiogenesis, as well as the invasion and metastasis of various types of cancer cells. Moreover, ginsenosides as combination therapy enhance the sensitivity of chemoresistant tumors to clinically used chemotherapeutic agents. This review sheds light on the molecular mechanisms underlying the cancer chemopreventive and/or chemotherapeutic activity of ginsenosides and their intestinal metabolites with particular focus on the modulation of cell signaling pathways associated with oxidative stress, inflammation, cell proliferation, apoptosis, angiogenesis and the metastasis of cancer cells.

Abstract
This study investigated the effect of red ginseng extract on metastasis of colon cancer cells in vitro and in vivo. Wound healing migration, cell motility, invasion, and activity, protein expression, and mRNA expression of matrix metalloproteinases (MMPs) were examined in SW480 human colon cancer cells. SW480 cells were cultured with or without 100 μg/L PMA in the absence or presence of various concentrations (100, 200, or 300 μg/mL) of red ginseng extract. Red ginseng extract treatment caused significant suppression of cell motility and invasion (p<0.05) in SW480 cells. Red ginseng extract inhibited MMP-2 and MMP-9 activity and their protein and mRNA expression in a dose-dependent manner (p<0.05) in SW480 cells. For experimental metastasis, BALB/c mice were injected intravenously with CT-26 mouse colon cancer cells in the tail vein, and were orally administered various concentrations (0, 75, 150, or 300 mg/kg body weight) of red ginseng extract for 3 weeks. Numbers of pulmonary nodules were significantly decreased in mice that were fed red ginseng extract (p<0.05). Plasma MMP-2 and MMP-9 activity significantly decreased in response to treatment with red ginseng extract in mice (p<0.05). These data suggest that red ginseng extract may be useful for prevention of cancer invasion and metastasis through inhibition of MMP-2 and MMP-9 pathways.

Abstract
Plant-derived active constituents and their semi-synthetic or synthetic analogs have served as major sources of anticancer drugs. 20(S)-protopanaxadiol (PPD) is a metabolite of ginseng saponin of both American ginseng (Panax quinquefolius L.) and Asian ginseng (Panax ginseng C.A. Meyer). We previously demonstrated that ginsenoside Rg3, a glucoside precursor of PPD, exhibits anti-proliferative effects on HCT116 cells and reduces tumor size in a xenograft model. Our subsequent study indicated that PPD has more potent antitumor activity than that of Rg3 in vitro although the mechanism underlying the anticancer activity of PPD remains to be defined. Here, we investigated the mechanism underlying the anticancer activity of PPD in human cancer cells in vitro and in vivo. PPD was shown to inhibit growth and induce cell cycle arrest in HCT116 cells. The in vivo studies indicate that PPD inhibits xenograft tumor growth in athymic nude mice bearing HCT116 cells. The xenograft tumor size was significantly reduced when the animals were treated with PPD (30 mg/kg body weight) for 3 weeks. When the expression of previously identified Rg3 targets, A kinase (PRKA) anchor protein 8 (AKAP8L) and phosphatidylinositol transfer protein α (PITPNA), was analyzed, PPD was shown to inhibit the expression of PITPNA while upregulating AKAP8L expression in HCT116 cells. Pathway-specific reporter assays indicated that PPD effectively suppressed the NF-κB, JNK and MAPK/ERK signaling pathways. Taken together, our results suggest that the anticancer activity of PPD in colon cancer cells may be mediated through targeting NF-κB, JNK and MAPK/ERK signaling pathways, although the detailed mechanisms underlying the anticancer mode of PPD action need to be fully elucidated.

Abstract
The ginsenoside Rg3(S), which is one of the exceptional components of Korean red ginseng extract, has been known to have anti-cancer, anti-metastatic, and anti-obesity effects. An enzymatic bioconversion method was developed to obtain the ginsenoside Rg3(S) with a high specificity, yield, and purity. Two glycoside hydrolases (BglBX10 and Abf22-3) were employed to produce Rg3(S) as a 100g unit. The conversion reaction transformed ginsenoside Rc to Rd using Abf22-3, followed by Rb1 and Rd to Rg3(S), using BglBX10. It was performed in a 10L jar fermenter at pH 6.0 and 37°C for 24h, with a high concentration of 50mg/ml of purified ginsenoside mixture obtained from ginseng roots. Finally, 144g of Rg3(S) was produced from 250g of root extract with 78±1.2% chromatographic purity. These results suggest that this enzymatic method would be useful in the preparation of ginsenoside Rg3(S) for the functional food and pharmaceutical industries.

Abstract
Mixed micelles are widely used to increase solubility and bioavailability of poorly soluble drugs. One promising antitumor drug candidate is 20(S)-protopanaxadiol (PPD), although its clinical application is limited by low water solubility and poor bioavailability after oral administration. In this study, we developed mixed micelles consisting of PPD-phospholipid complexes and Labrasol(®) and evaluated their potential for oral PPD absorption. Micelles were prepared using a solvent-evaporation method, and their physicochemical properties, including particle size, zeta potential, morphology, crystal type, drug loading, drug entrapment efficiency, and solubility, were characterized. Furthermore, in vitro release was investigated using the dialysis method, and transport and bioavailability of the mixed micelles were investigated through a Caco-2 cell monolayer and in vivo absorption studies performed in rats. Compared with the solubility of free PPD (3 μg/mL), the solubility of PPD in the prepared mixed micelles was 192.41 ± 1.13 μg/mL in water at room temperature. The in vitro release profiles showed a significant difference between the more rapid release of free PPD and the slower and more sustained release of the mixed micelles. At the end of a 4-hour transport study using Caco-2 cells, the apical-to-basolateral apparent permeability coefficients (P(app)) increased from (1.12 ± 0.21) × 10(6) cm/s to (1.78 ± 0.16) × 10(6) cm/s, while the basolateral-to-apical P(app) decreased from (2.42 ± 0.16) × 10(6) cm/s to (2.12 ± 0.32) × 10(6). In this pharmacokinetic study, compared with the bioavailability of free PPD (area under the curve [AUC](0-∞)), the bioavailability of PPD from the micelles (AUC(0-∞)) increased by approximately 216.36%. These results suggest that novel mixed micelles can significantly increase solubility, enhance absorption, and improve bioavailability. Thus, these prepared micelles might be potential carriers for oral PPD delivery in antitumor therapies.

Abstract
Accumulating evidence suggests that Ginsenoside Rg3 appears to inhibit tumor growth including Lewis lung carcinoma, intestinal adenocarcinomas or B16 melanoma by inhibiting cell proliferation, tumor cell invasion and metastasis. Endothelial progenitor cells (EPCs) appear to play a key role in the growth of early tumors by intervening with the angiogenic switch promoting tumor neovessel formation by producing angiogenic cytokines during tumor progression. This paper reports a novel mechanism of Ginsenoside Rg3, a candidate anticancer bio-molecule, on tumor angiogenesis by inhibiting the multiple bioactivities of EPCs. When Ginsenoside Rg3 was applied to the ex vivo cultured outgrowth ECs, a type of EPCs, it inhibited the cell proliferation, cell migration and tubular formation of EPCs. Importantly, Ginsenoside Rg3 attenuated the phosphorylation cascade of the VEGF dependent p38/ERK signaling in vitro. The xenograft tumor model clearly showed that Ginsenoside Rg3 suppresses tumor growth and tumor angiogenesis by inhibiting the mobilization of EPCs from the bone marrow microenvironment to the peripheral circulation and modulates VEGF-dependent tumor angiogenesis. In conclusion, this study provides a potential therapeutic molecule, Ginsenoside Rg3, as an anticancer drug by inhibiting the EPC bioactivities.

Ginsenoside Rg3 attenuates cell migration via inhibition of aquaporin 1 expression in PC-3M prostate cancer cells. Eur J Pharmacol 2012; 683:27-34. [PMID: 22426160 DOI: 10.1016/j.ejphar.2012.02.040] [Citation(s) in RCA: 70] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2011] [Revised: 02/15/2012] [Accepted: 02/28/2012] [Indexed: 11/23/2022]
Abstract
Ginsenoside Rg3 (Rg3), one of the bioactive extracts found in ginseng root, was reported to have anti-cancer activity in various cancer models. The anti-proliferation effect of Rg3 on prostate cancer cells has been well reported. To test whether Rg3 has an anti-metastatic effect on prostate cancer, we treated a highly metastatic PC-3M prostate cancer cell line with Rg3. We found that Rg3 (10μM) led to remarkable inhibition of PC-3M cell migration. Simultaneously, exposure to Rg3 suppressed expression of the aquaporin 1 (AQP1) water channel protein, which has previously been reported to be involved in cell migration. Overexpression of AQP1 attenuated Rg3-induced inhibition of cell migration, and introduction of a shRNA targeting AQP1 abrogated the inhibitory effect of Rg3, although the basal level of cell migration was decreased by RNA interference. In mechanism study, estrogen receptor- and glucocorticoid receptor-dependent pathways are proved uninvolved in the AQP1 regulation by Rg3. However, Rg3 treatment triggered the activation of p38 MAPK; and SB202190, a specific inhibitor of p38 MAPK, antagonized the Rg3-induced regulation of AQP1 and cell migration, suggesting a crucial role for p38 in the regulation process. Deletion analysis of the promoter region of AQP1 was also conducted using dual-luciferase assay, which indicated that the -1000 bp to -200 bp promoter region was involved in the AQP1 regulation by Rg3. In all, we conclude that Rg3 effectively suppresses migration of PC-3M cells by down-regulating AQP1 expression through p38 MAPK pathway and some transcription factors acting on the AQP1 promoter.

Abstract
Endothelial progenitor cells (EPCs) play a critical role both in vascular repair after cell transplantation for ischemic diseases and in the growth of early tumors by intervening with the angiogenic switch during tumor progression. This paper reports on the effect of ginsenoside Rg3 in EPCs as a candidate angiogenesis inhibitor for in vitro functional assays. CD34⁺ cells were isolated from human cord blood and the study investigated whether or not ginsenoside Rg3 regulated EPC bioactivities including cell proliferation, differentiation, migration and tube formation. Although ginsenoside Rg3 did not affect the ex vivo expansion of CD34 and/or KDR (VEGFR2) stem/progenitor cells, treatment with ginsenoside Rg3 led to a significant decrease in CD34-expressing cells, specifically the absolute number of expanded CD34⁺ cells. Importantly, a significantly decreased number of EPC colony-forming units among human cord blood-derived CD34⁺ cells was observed, implying that ginsenoside Rg3 inhibited EPC differentiation, in particular, the commitment to primitive EPC colonies (the early stage of EPC differentiation). Moreover, treatment of CD34-derived EPCs with ginsenoside Rg3 resulted in the attenuation of VEGF-dependent Akt/eNOS signaling as well as the inhibition of migration and tube formation. In conclusion, this study provides in vitro evidence for ginsenoside Rg3 as a potential therapeutic molecule, specifically as an angiogenesis inhibitor that functions by attenuating EPC bioactivities.

Abstract
Background Immuno-modulatory effects of ginseng, including both immuno-stimulatory and immuno-suppressive effects, have been widely reported. This study aims to determine whether the paradoxical immuno-modulatory effect is related to unique phytochemical profiles of different North American (NA) ginseng, namely aqueous (AQ) and alcoholic (ALC) extracts. Methods AQ and ALC extracts were prepared and their immuno-bioactivity were studied in vitro in murine macrophages (Raw 264.7) through measuring the direct stimulatory production of pro-inflammatory mediator and cytokines as well as the suppression of lipopolysaccharide (LPS)-stimulatory response by the two extracts. Gel permeation chromatography was used to fractionate and isolate phytochemicals for characterization of ginseng extracts. Results AQ extract up-regulated the production of nitric oxide (NO), tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6) while ALC extract did not. ALC extract but not AQ extract suppressed LPS-induced macrophage NO and TNF-α production. These immuno-stimulatory and suppressive effects were exhibited at similar extract concentrations. Moreover, the macrophage-stimulating activity of the AQ extract was inhibited in the presence of ALC extract. Fractionation of AQ extract revealed the presence of two major peaks at 230 nm with average molecular weights of 73,000 and 37,000 Da. The first fraction had similar elution volume as the crude polysaccharide (PS) fraction isolated from the AQ extract, and it was the only bioactive species. Parallel fractionation study of ALC extract yielded similar elution profiles; however, both sub-fractions were devoid of PS. Fraction I of the ALC extract suppressed LPS-induced NO production dose-dependently. Conclusion ALC extract of NA ginseng, which was devoid of PS, was immuno-inhibitory whereas the AQ extract, which contained PS, was immuno-stimulatory. These extract-related anti-inflammatory and pro-inflammatory effects may be considered as the Yin and Yang actions of ginseng.

Abstract
Antitumor effects of a ginsenoside Rg(3)-fortified red ginseng preparation (Rg(3)-RGP) were investigated in human non-small cell lung carcinoma (H460) cells using in vitro cytotoxicity assay and in vivo nude mouse xenograft model. Immunomodulatory effects of the preparation were also assessed by measuring the facilitating activities on the nitric oxide (NO) release from peritoneal macrophages, in vitro and in vivo lymphocyte proliferation, and the carbon clearance from circulating blood. In a cell level, Rg(3)-RGP exerted H460 cytotoxicity and facilitated splenocyte proliferation at very high concentrations, without affecting NO production. However, oral administration of Rg(3)-RGP (100-300 mg/kg) enhanced carbon particle-phagocytic index of blood macrophages up to 360-397% of control value. In addition, Rg(3)-RGP significantly increased the splenocyte proliferation (23% at 100mg/kg). In tumor-bearing mice, 28-day oral treatment with Rg(3)-RGP (100mg/kg) remarkably suppressed the tumor growth, leading to the decrease of the tumor volume and weight by 30-31%, which was comparable to the effect (27-29% reduction) of doxorubicin (2mg/kg at 3-day intervals). While Rg(3)-RGP did not cause adverse effects, intravenous injection of doxorubicin markedly decreased body and testes weights, and exhibited severe depletion of spermatogenic cells in the atrophic seminiferous tubules. These results indicate that Rg(3)-RGP exerts antitumor activities via indirect immunomodulatory actions, without causing adverse effects as seen in doxorubicin.

Abstract
BACKGROUND Ginsenoside Rg3 is an extract from the natural product ginseng. Previous studies have linked Rg3 with anti-metastasis of cancer in vivo and in vitro. CXC receptor 4 (CXCR4) is a vital molecule in migration and homing of cancer to the docking regions. METHODS In this study, the effects of Rg3 on CXCR4 expression were investigated in a breast cancer cell line. Immunohistochemistry, chemotaxis and wound healing mobility assays were performed in cultured MDA-MB-231 cells. RESULTS At a dosage without obvious cytotoxicity, Rg3 treatment elicits a weak CXCR4 stain color, decreases the number of migrated cells in CXCL12-elicited chemotaxis and reduces the width of the scar in wound healing. CONCLUSION This work suggests that Rg3 is a new CXCR4 inhibitor from a natural product.

Abstract
Previous studies have shown that the ginseng saponin metabolite, Compound K (20-O-d-glucopyranosyl-20(S)-protopanaxadiol, IH901), suppresses proliferation of various cancers and induces apoptosis. AMP-activated protein kinase (AMPK) is a sensor of cellular energy states and is involved in apoptosis of cancer cells. We hypothesized that Compound K may exert cytotoxicity in MCF-7 human breast cancer cells through modulation of AMPK, followed by a decrease in cyclooxygenase-2 (COX-2) expression. Compound K inhibited cell growth, induced apoptosis via generation of reactive oxygen species (ROS), as well as decreasing COX-2 expression and prostaglandin E(2) (PGE(2)) levels. These effects of Compound K were induced via an AMPK-dependent pathway and were abrogated by a specific AMPK inhibitor. These results suggest that Compound K induced apoptosis by modulating AMPK-COX-2 signaling in MCF-7 human breast cancer cells.

Abstract
AIM To investigate the effects and possible mechanisms of tanshinone II-A, an alcohol extract of the root of Salvia miltiorrhiza Bunge, on tumor invasion and metastasis of human colon carcinoma (CRC) cells. METHODS The effects of tanshinone II-A on invasion and metastasis of CRC cell lines HT29 and SW480 were evaluated by in vitro and in vivo assays. Western blotting was used to investigate possible molecular mechanisms of tanshinone II-A anti-cancer actions. RESULTS Tanshinone II-A inhibited migration and invasion of CRC cells in a dose-dependent manner. The inhibitory effect also depended on time, with the most significant effects observed at 72 h. Tanshinone II-A also significantly inhibited in vivo metastasis of colon carcinoma SW480 cells. It inhibited in vitro and in vivo invasion and metastasis of CRC cells by reducing levels of urokinase plasminogen activator (uPA) and matrix metalloproteinases (MMP)-2 and MMP-9, and by increasing levels of tissue inhibitor of matrix metalloproteinase protein (TIMP)-1 and TIMP-2. Tanshinone II-A was also shown to suppress the nuclear factor-kappaB (NF-kappaB) signal. CONCLUSION Tanshinone II-A inhibited in vitro and in vivo invasion and metastasis of CRC cells. The effect resulted from changes in the levels of uPA, MMP-2, MMP-9, TIMP-1 and TIMP-2, and apparent inhibition of the NF-kappaB signal transduction pathway.

Abstract
Pretreatment of NCI-H460 human lung cancer cells with compound K produced by intestinal bacteria enhances gamma-ray radiation-induced cell death. Increases in apoptosis induced by combined treatment are made apparent in the observation of nuclear fragmentation, loss of mitochondrial membrane potential (Deltapsi), and activation of caspase 3. Apoptosis induced by compound K and gamma-ray radiation is associated with reactive oxygen species (ROS) generation. Furthermore, compound K, in combination with gamma-ray radiation, has an enhanced effect in the regression of NCI-H460 tumor xenografts of nude mice. These results suggest that compound K has possible application for cancer therapy when used in combination with gamma-ray radiation.

Abstract
Ginseng is a well known herbal medicine in Asia, and ginsenoside Rg3 has anti-cancer and various pharmacological effects. In particular, 20S-ginsenoside Rg3 may increase the anti-proliferative effects of chemotherapy. The authors investigated the mechanism of the anti-proliferative effect of 20S-Rg3 at the protein level in HT29 colon cancer cells. MTT, caspase-3 assays, and flow cytometry analysis were performed to determine cytotoxicity and apoptosis, and proteomic analysis was performed by two-dimensional gel electrophoresis and MALDI-TOF/TOF MS, and a database was used to identify protein changes in 20S-Rg3 treated HT29 cells. The proteins identified included down-regulated Rho GDP dissociation inhibitor, up-regulated tropomyosin1, and annexin5 and glutathione s-transferase p1, which are apoptosis associated proteins. The anti-proliferative mechanism of 20S-Rg3 was found to be involved in mitotic inhibition, DNA replication, and repair and growth factor signaling. The findings of this study suggest that the cytotoxicity of 20S-Rg3 in colon cancer is dependent on several mechanisms, including apoptosis.

Abstract
Colorectal cancer remains one of the most prevalent cancer and a leading cause of cancer related death in the US. Many currently used chemotherapeutic agents are derived from botanicals. Identifying herbal sources, including those from ginseng family, to develop better anti-cancer therapies remains an essential step in advancing the treatment of the cancer. In this article, potential roles of ginseng herbs, especially American ginseng and notoginseng, in colorectal cancer therapeutics are presented. The major pharmacologically active constituents of ginsengs are ginsenosides, which can be mainly classified as protopanaxadiol and protopanaxatriol groups. Structure-activity relationship between their chemical structures and pharmacological activities are discussed. In addition, various steaming temperature and time treatment of the ginseng herbs can change ginsenoside profiles, and enhance their anti-cancer activities. This heat treatment process may increase the role of ginseng in treating colorectal cancer.

Abstract
Ginsenoside Rp1 (G-Rp1) is a novel ginseng saponin with a chemopreventive action. In this study, we examined the anti-metastatic activities of G-Rp1 using relevant in vitro assays and in vivo metastasis models. Using a U937 cell-cell adhesion assay, we found that exogenously added G-Rp1 down-regulates beta1-integrin (CD29) activation at concentrations between 10 to 40 microM and suppresses the in vitro tube formation of human umbilical vein endothelial cells (HUVECs). Furthermore, this compound directly blocked cell viability of cancer cells such as A549 and HCT15 cells. In agreement with in vitro findings, G-Rp1 strongly inhibited the metastatic lung transfer of B16-F10 melanoma cells, which have a high surface level of beta1-integrins, without altering body weight. Therefore, these results suggest that G-Rp1 may act as an anti-cancer agent by strongly inhibiting cell viability and metastatic processes, presumably by inhibiting the adhesion of tumor cells and vessel formation.

Abstract
AIM: To investigate the effects of ginsenoside Rg3 on the expression of Pim-3 and Bad phosphorylated proteins including pBad (Ser112) and pBad (Ser136) in human hepatocarcinoma cell line SMMC-7721.
METHODS: SMMC-7721 cells were exposed to 0, 5, 10, 20, 40 and 80 μmol/L ginsenoside Rg3 for 24 h. The effect of ginsenoside Rg3 on cell proliferation was measured using methyl thiazolyl tetrazolium (MTT) assay, and the apoptosis of SMMC-7721 cells was evaluated by inverted microscopy and flow cytometry. The expression of Pim-3 and pBad (Ser112) and pBad (ser136) were measured by Western blot.
RESULTS: The inhibitory rates were 4.69%, 15.53%, 22.17%, 50.97% and 61.65% respectively, after SMMC-7721 cells were exposed to 5, 10, 20, 40 and 80 μmol/L ginsenoside Rg3 for 24 h. Marked morphological changes of apoptosis were observed following exposure to 5-80 μmol/L ginsenoside Rg3. Flow cytometry showed the apoptosis rate was 0.39% in the normal control cells and 16.49% in the cells exposed to 80 μmol/L ginsenoside Rg3 for 24 h, indicating a marked elevation in apoptosis rate (P < 0.01). Ginsenoside Rg3 had no marked influences on the total Bad protein expression. Pim-3 expression was decreased with elevated ginsenoside Rg3 concentration, and the pBad (Ser112) was increased with elevated ginsenoside Rg3. But the pBad (Ser136) was not expressed.
CONCLUSION: The anti-cancer action of ginsenoside Rg3 may be associated with the decreased expression of Pim-3 and the increased expression of pBad (Ser112).

Abstract
Despite the significant anti-tumor activities, cyclophosphamide (CP) also shows cytotoxicity to normal cells. In order to explore the protective effects of drugs against CP-induced adverse effects, 20(S)-ginsenoside Rg(3) was tested for its possibly protective activities on CP-induced DNA damage and cell apoptosis in mouse bone marrow cells or peripheral lymphocyte cells. In the current study, the alkaline single cell gel electrophoresis (comet assay), flow cytometry assay with annexin V-FITC/PI and AO/EB staining assay were employed to measure DNA strand breakage and cell apoptosis, respectively. The activities of SOD and GPx and the contents of MDA were also tested by the various colormetric methods. The results showed that CP at a dose of 100 mg/kg, i.p. significantly caused DNA damages in both mouse bone marrow cells and peripheral lymphocyte cells, and markedly inhibited the activities of GPx and SOD and increased MDA contents in mouse blood. Moreover, CP at a dose of 200 mg/kg, i.p. triggered apoptosis in mouse bone marrow cells. On the other hand, 20(S)-ginsenoside Rg(3) orally administered at a dose of 20 mg/kg to the animals once a day for 2 days significantly inhibited CP-induced DNA damages in mouse bone marrow cells and peripheral lymphocyte cells, decrease the apoptotic numbers of bone marrow cells, antagonized the reduction of the activities of SOD and GPx, and the increase in MDA contents. In conclusion, 20(S)-ginsenoside Rg(3) showed the significant protective effects on CP-induced cell DNA damage and apoptosis. These effects might be partially attributed to its protective actions against CP-induced oxidative stress.

Abstract
Panax ginseng produces triterpene saponins called ginsenosides, which are classified into two groups by the skeleton of aglycones, namely dammarane type and oleanane type. Dammarane-type ginsenosides dominate over oleanane type not only in amount but also in structural varieties. However, their sapogenin structure is restricted to two aglycones, protopanaxadiol and protopanaxatriol. So far, the genes encoding oxidosqualene cyclase (OSC) responsible for formation of dammarane skeleton have not been cloned, although OSC yielding oleanane skeleton (beta-amyrin synthase) has been successfully cloned from this plant. In this study, cDNA cloning of OSC producing dammmarane triterpene was attempted from hairy root cultures of P. ginseng by homology based PCR method. A new OSC gene (named as PNA) obtained was expressed in a lanosterol synthase deficient (erg7) Saccharomyces cerevisiae strain GIL77. LC-MS and NMR analyses identified the accumulated product in the yeast transformant to be dammarenediol-II, demonstrating PNA to encode dammarenediol-II synthase.

Abstract
Aberrant expression of matrix metalloproteinase-9 (MMP-9) is implicated in the process of invasion and angiogenesis of malignant tumors as well as in inflammatory diseases of the CNS. Therefore, the development of compounds that can inhibit or suppress MMP-9 is required to treat brain tumors. We investigated the effects of a ginseng saponin metabolite, compound K (20-O-(beta-D-glucopyranosyl)-20(S)-protopanaxadiol), on MMP-9 expression in human astroglioma cells. Compound K significantly inhibited the secretion and protein expression of MMP-9 induced by PMA. The inhibitory effect of compound K on MMP-9 expression correlated with decreased MMP-9 mRNA levels and suppression of MMP-9 promoter activity. The compound K-mediated inhibition of MMP-9 gene expression appears to occur via AP-1 because its DNA-binding and transcriptional activities were suppressed by the agent. Furthermore, compound K significantly repressed the PMA-mediated activation of p38 MAPK, ERK and JNK, which are upstream modulators of AP-1. Finally, compound K inhibited the in vitro invasiveness of glioma cells. Therefore, inhibition of MMP-9 expression by compound K might have therapeutic potential for controlling the growth and invasiveness of brain tumors.

Abstract
Triterpenoid saponins, which are present in plants and some marine animals, exert various important pharmacological effects. The present study examines the effects of adianthifoliosides A, B, and D (AdA, AdB, and AdD) together with two prosapogenins (Pro1 and Pro2) obtained from Albizia adianthifolia (Mimosaceae) on human leukemia T-cells (Jurkat cells) and on splenocytes. AdA, AdB, and AdD were found to exhibit a cytotoxic effect on Jurkat cells, whereas the prosapogenins were found to exert a lymphoproliferative effect on this cell type. Furthermore, all tested compounds were found to exert a synergistic lymphoproliferative activity with concanavalin A (ConA) on splenocytes. The concentrations where the saponins were found to be cytotoxic on Jurkat cells are far below the concentration of hemolysis. These results indicate that another mechanism than membrane permeabilization formation is responsible of the cell cytotoxicity. Thus, we demonstrated that at 5 microM for AdA and at 1 microM for AdD, these compounds induce apoptosis in Jurkat cells. Early apoptotic events were detected by flow cytometry analysis by using a double annexin-V-FITC and propidium iodide staining. In addition, a disrupted mitochondrial membrane potential was observed in cells treated with AdA, AdB, and AdD. Furthermore, a DNA ladder was observed when Jurkat cells were incubated with 1 microM AdD for 24h. By comparison between the biological activities of the native compounds with the prosapogenins, we show in this work the important role of the acylation and esterification by different moieties at C-21 and C-28 of the aglycone (acacic acid) in the apoptosis-inducing capacity. Particularly, the monoterpene-quinovosyl moiety is shown to be important for the induction of apoptosis.
