Characterization of Novel Exopolysaccharides from Enterococcus hirae WEHI01 and Its Immunomodulatory Activity. Foods 2022; 11:foods11213538. [DOI: 10.3390/foods11213538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 10/23/2022] [Accepted: 11/04/2022] [Indexed: 11/09/2022] Open
Abstract
Exopolysaccharide (EPS) from probiotic Enterococcus hirae WEHI01 was isolated and purified by anion exchange chromatography and gel chromatography, the results of which show that the EPS consists of four fractions, namely I01-1, I01-2, I01-3, and I01-4. As the main purification components, I01-2 and I01-4 were preliminarily characterized for their structure and their immunomodulatory activity was explored. The molecular weight of I01-2 was 2.28 × 104 Da, which consists mainly of galactose, and a few other sugars including glucose, arabinose, mannose, xylose, fucose, and rhamnose, while the I01-4 was composed of galactose only and has a molecular weight of 2.59 × 104 Da. Furthermore, the results of an evaluation of immunomodulatory activity revealed that I01-2 and I01-4 could improve the viability of macrophage cells, improve phagocytosis, boost NO generation, and encourage the release of cytokines including TNF-α and IL-6 in RAW 264.7 macrophages. These results imply that I01-2 and I01-4 could improve macrophage-mediated immune responses and might be useful in the production of functional food and medications.

Moon in the treatment of hepatocellular carcinoma. JOURNAL OF ETHNOPHARMACOLOGY 2022; 293:115285. [PMID: 35429621 DOI: 10.1016/j.jep.2022.115285] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 03/29/2022] [Accepted: 04/06/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Marsdenia tenacissima (Roxb.) Moon, (M. tenacissima) a traditional herbal medicine, has been used for thousands of years. It is noted in Dian Nan Ben Cao that M. tenacissima is bitter in flavor and cold in property, and extracts possess diverse pharmacological effects, including immunomodulation and anti-tumor activities. AIM OF THE STUDY The anti-tumor effects of M. tenacissima extracts (MTE) have been repeatedly confirmed, and this medicine has also been extensively applied in cancer treatment or prognostic adjuvant therapy, with significant curative effect. This study aims to comprehensively analyze the anti-tumor mechanism of M. tenacissima starting from the key features of traditional Chinese medicine and by studying the main active components individually to identify anti-tumor targets in the context of hepatocellular carcinoma. MATERIALS AND METHODS Molecular network profiling and multi-omic joint analyses were conducted using an H22 mouse model of hepatocellular carcinoma to determine the main active ingredients in MTE and the underlying anti-tumor mechanisms. RESULTS Tenacissosides I, H, and G (TI,TH and TG) were found to be the likely active ingredients of MTE in the treatment of hepatocellular carcinoma. These compounds were shown to promote apoptosis, inhibit angiogenesis and improve immune function through targeting P53, JAK-1 and HIF1α, respectively. CONCLUSIONS For the first time, based on the theory that multiple components and multiple targets synergistically exert the beneficial effects of a traditional Chinese medicine, this paper comprehensively analyzes the mechanisms of action of M. tenacissima and provides a novel strategy for the subsequent development of anti-tumor therapies.

Abstract
Previous studies identified that extracts of Talinum triangulare rich in flavonoids and phenolic acids showed antioxidative and immunomodulatory activities. In this study, the L9 orthogonal array was used to determine the optimal extraction conditions for water-extracted polysaccharides of T. triangulare (TTP) by hot reflux extraction and ultrasonic assisted extraction (UAE) methods. Results showed that while both extraction methods obtained a maximum polysaccharide yield of 3.1%, the optimal conditions for obtaining TTP was by UAE method. TTP was separated into large (LTTP) and small (STTP) molecular weights by dialysis. Since LTTP showed better effects than STTP in inducing macrophages to produce nitric oxide (NO) and indirectly inhibiting human cervical cancer HeLa cells, six different LTTP fractions were separated using anion-exchange chromatography. Contents of polysaccharides, triterpenoids, polyphenols, and proteins and molecular weights of major polysaccharide in each fraction were analyzed. The F1 fraction of LTTP, which showed the highest inducing ability of mouse RAW264.7 macrophages to secrete NO and tumor necrosis factor-α, showed the most significant indirect inhibitory effect of human colon cancer SW620 cells. These results suggest that LTTP, especially the F1 fraction, of T. triangulare may be used in health foods or Chinese medicine for its immunomodulatory potential.

Abstract
Mushrooms with enhanced medicinal properties focus on finding such compounds that could modulate the human body's immune systems. Mushrooms have antimicrobial, antidiabetic, antiviral, hepatoprotective, antitumor, and immunomodulatory properties due to the presence of various bioactive components. β-glucans are the major constituent of the mushroom cell wall and play a significant role in their biological activity. This review described the techniques used in the extraction of the active ingredients from the mushroom. We highlighted the structure of the bioactive polysaccharides present in the mushrooms. Therapeutic applications of different mushrooms were also described. It is interesting to note that mushrooms have the potential sources of many bioactive products that can regulate immunity. Thus, the development of functional medicinal food based on the mushroom is vital for human welfare.

Abstract
Coriolus versicolor is an edible medicinal mushroom in China. Two polysaccharides, named as CVPn and CVPa were separated from the dried fruiting bodies of Coriolus versicolor by water extraction and ethanol precipitation. Their chemical structures were well elucidated with overall consideration of monosaccharide composition, methylation analysis and 1D/2D-NMR spectra data. The bioactivities on RAW 264.7 macrophages cells were evaluated, and further structure-bioactivity relationships were concluded. With molecular weight of 29.7 kDa for CVPn and 50.8 kDa for CVPa, the two isolated polysaccharides were both composed of (l → 4)-β-/(1 → 3)-β-d-glucopyranosyl group as backbone with branches attached at O-6 site. Comparing to CVPn, CVPa with relative high molecular weight and less branches showed significant induction of NO production, obvious augmentation of iNOS and TNF-α mRNA expression level, and phagocytosis on RAW 264.7 cells. These results clarified that CVP polysaccharides with less branches and high molecular weight possessed enhanced immunomodulatory ability, and this finding could be a reference for the utilization of Coriolus versicolor.

Abstract
The "self-homing" of cancer cells to primary or metastatic tumor sites indicates that they could serve as vehicles for self-targeted cancer therapy; this suggests a promising method for treating end-stage cancer. Inspired by this, we propose that engineering cancer cells to carry efficient "coup" molecules for in situ activation of immune cells in or near tumor sites to attack tumors is a promising strategy for cancer therapy. Therefore, herein we explored the potential of engineered tumor cells to enhance their anticancer activity by stimulating immune cells. We armed tumor cell surfaces with specific glycopolymer-ligands that bind to lectins on macrophages or dendritic cells by combining HaloTag protein (HTP) fusion technique with reversible addition-fragmentation chain transfer (RAFT) polymerization. We demonstrated that two synthetic well-defined glycopolymers containing, respectively, N-acetylglucosamine and N-acetylmannosamine units, were introduced and stably presented on the cell surfaces via the stable covalent binding of chloroalkane-terminated polymers with membrane-bound HTP. Furthermore, it was shown that the glycopolymer-engineered HeLa cells with HTP anchors increased expression of the typical marker for M1-type macrophages (CD86) and upregulated secretion of pro-inflammatory cytokines (IL-12p70, TNF-α, and iNOS), thereby accelerating HeLa cell lysis. The maturation of dendritic cells was also promoted. This study demonstrates the strong potential of glycopolymer-engineered tumor cells in cancer immunotherapy.

Abstract
At present, the chemotherapy of advanced inoperable liver cancer is limited with serious side effects. Curcumin possesses multiple cancer preventive activities and low safety concerns. However, its poor solubility and instability in water pose significant pharmacological barriers to its clinical application. In this study, we presented a novel delivery system – the glycyrrhetinic acid modified curcumin-loaded cationic liposomes (GAMCLCL) and investigated its antitumor activities on HepG2 cells in vitro and in H22 tumor-bearing mice. The experimental results demonstrated that GAMCLCL was a cationic liposome and could be Intravenous administration. Compared to free curcumin, GAMCLCL exhibited stronger antitumor activities in vitro and in vivo. The antitumor results of GAMCLCL after intravenous administration were very similar to those after intratumoral administration. The main activities of GAMCLCL and curcumin included inhibition of HepG2 cell proliferation, inhibition of tumor growth, reduction of tumor microvascular density, down-regulation of the expression of VEGF protein, and up-regulation of the expression of Caspases3 protein in H22 tumor tissues. Furthermore, GAMCLCL improved the parameters of WBC, RBC, ALT, CRE, LDH of H22 tumor-bearing mice. Curcumin is a nontoxic natural compound with definite antitumor activities, its antitumor effects can be enhanced by preparation of GAMCLCL.

Abstract
In this study, a homogeneous polysaccharide (RPS-1) was extracted from liquid-cultured mycelia of Rhizopus nigricans. The weight-average molecular weight of RPS-1 was 1.617 × 107 g/mol and structural characterization indicated that RPS-1 was a non-starch glucan which consisted of a backbone structure of (1→4)-linked α-d-glucopyranosyl residues substituted at the O-6 position with α-d-glucopyranosyl branches. RPS-1 stimulated the production of nitric oxide and tumor necrosis factor-α by triggering phosphorylation of mitogen-activated protein kinases and nuclear translocation of nuclear factor kappa B p65 in RAW 264.7 macrophage cells. Moreover, intragastric administration of RPS-1 improved the immune function of CT26 tumor-bearing mice and significantly inhibited the growth of transplanted tumor. In combination with 5-FU, RPS-1 enhanced antitumor activity of 5-FU and alleviated its toxicity on immune system. These findings suggested that RPS-1 has the potential for the development of functional foods and dietary supplements.

Abstract
OBJECTIVE To investigate the anti-cancer effect of Polygonatum sibiricum polysaccharides (PSP) and the underlying mechanism. METHODS Tumor-bearing mice were randomly divided into normal saline (NS) group, adriamycin (ADM) group, PSP group and lipopolysaccharide (LPS) group. RAW264.7 cells were pre-treated with or without TLR4 inhibitor or MyD88 inhibitor. Quantitative RT-PCR and Western blot were performed to detect the mRNA and protein expressions, respectively. ELISA and Griess reaction was used to measure cytokines and NO levels. Flow cytometry was employed to examine T-lymphocyte subset and CCK-8 assay was used for cell viability. RESULTS The in vivo experiment found that PSP inhibited tumor growth and improved the spleen index, thymus index, the cytokines secretion and CD4+/CD8+ lymphocytes ratio. Compared with the NS group, the mRNA and protein expressions of the critical nodes inTLR4-MAPK/NF-κB signaling pathways (except TRAM) significantly increased in PSP group, as well as the NO and cytokines levels. Nevertheless, PSP had no obvious effects on TRAM. Further analysis showed that PSP effects on the critical nodes in TLR4-MAPK/NF-κB signaling pathways were suppressed by inhibitor in vitro. CONCLUSION The immunoenhancement effect of PSP against lung cancer is mediated by TLR4-MAPK/NF-κB signaling pathways.

Abstract
The actinomycetes strain, lut0910, was isolated from polluted soil and identified as the Rhodococcus species with 99% similarity based on the sequence analysis of 16S recombinant DNA. The extract of this strain demonstrated in vivo and in vitro antitumor activity. The treatment of two human cancer cell lines, hepatocellular carcinoma HepG2 and cervical carcinoma Hela cells, with the lut0910 extract caused the delay in cell propagation in a dose-dependent manner with an IC50 of 73.39 and 33.09 µg/mL, respectively. Also, the oral administration of lut0910 extract to the mice with a solid tumor resulted in the inhibition of tumor growth in comparison with a placebo group. The thymus and spleen indexes were significantly increased in mice groups treated with the lut0910 extract. The histopathological changes of the tumor tissues showed that there were massive necrotic areas in the tumor tissues after treatment with different doses of the lut0910 extract. Our result would provide a new way and potent source for development of new anticancer agent from the polluted environment.

Abstract
Blueberries are a rich source of anthocyanins, which are associated with health benefits contributing to a reduced risk for many diseases. The present study identified the functional Gardenblue blueberry (Vaccinium ashei Reade) anthocyanin extracts (GBBAEs) and evaluated their capacity and underlying mechanisms in protecting murine RAW 264.7 cells from lipopolysaccharide (LPS)-stimulated inflammation in vitro. Enzyme-linked immunosorbent assay (ELISA) kit results showed that GBBAEs significantly inhibited the production of nitric oxide (NO), prostaglandin E2 (PGE2), interleukin-6 (IL-6), IL-1β, and interferon-γ (INF-γ). Real-time polymerase chain reaction (PCR) analysis indicated that the mRNA expression levels of IL-6, IL-1β, tumor necrosis factor-α (TNF-α), monocyte chemoattractant protein-1 (MCP-1), and cyclooxygenase 2 (COX-2) were suppressed in LPS-stimulated RAW 264.7 cells. Additionally, Western blot analysis was used to evaluate the relative protein expression levels of COX-2 and nuclear factor-κB p65 (NF-κBp65). All these results suggested the potential use of GBBAEs as a functional food for the treatment of inflammatory diseases.

Abstract
Platycodin D (PD), a major saponin derived and isolated from the roots of Platycodon grandiflorum, exerts potent growth inhibition and strong cytotoxicity against various cancer cell lines. However, the anti-tumor efficacy of PD on H22 hepatocellular carcinoma remains unknown. In the present study, we aimed to explore the anti-hepatoma activity in vivo and the underlying mechanism of PD in H22 tumor-bearing mice. The results revealed that PD could considerably suppress tumor growth with no significant side effects on immune organs and body weight. Further investigations showed that the levels of serum cytokines, including interferon gamma (IFN-γ), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-2 (IL-2), were enhanced by PD administration. On the other hand, PD inhibited the production of vascular endothelial growth factor (VEGF) in serum of H22 tumor mice. Additionally, the observations from H&E and Hoechst 33258 staining results demonstrated that PD noticeably induced apoptosis in H22 hepatocellular carcinoma cells. Importantly, immunohistochemical analysis showed that PD treatment increased Bax expression and decreased Bcl-2 and VEGF expression of H22 tumor tissues in a dose-dependent manner. Taken together, the findings in the present investigation clearly demonstrated that the PD markedly suppressed the tumor growth of H22 transplanted tumor in vivo at least partly via improving the immune functions, inducing apoptosis, and inhibiting angiogenesis.

Abstract
A polysaccharide fraction, here called POP1, was purified from the leaves of Platycladus orientalis (L.) Franco by water extraction and alcohol precipitation. Physicochemical characterization indicated that POP1 had a relative molecular weight of 8.10 × 10(3) Da and consisted of rhamnose (5.74%), arabinose (12.58%), mannose (10.97%), glucose (64.96%), and galactose (6.55%). The main linkage types of POP1 consisted of (1→5)-linked α-l-Ara, (1→3)-linked α-l-Man, (1→6)-linked β-l-Rha, (1→4)-linked α-d-Glc, (1→6)-linked α-d-Glc, (1→6)-linked β-d-Gal, (1→3,6)-linked β-d-Gal, and termination with α-l-Man and α-d-Glc residues based on periodate oxidation, Smith degradation, methylation, and NMR analysis. POP1 exhibited excellent immunostimulating activity by enhancing macrophage NO, TNF-α, IL-6, and IL-12 secretion and activating related mRNA expression. Besides, POP1 showed significant anti-HBV activity through inhibiting the expression of HBsAg (IC50 = 1.33 ± 0.12 mg/mL) and HBeAg (IC50 = 1.67 ± 0.13 mg/mL) and interfering with the HBV DNA replication (IC50 = 0.80 ± 0.03 mg/mL). The present study suggested that POP1 could be used as immunoregulatory agent in functional foods for the prevention of HBV infection.

Abstract
Although previous studies confirmed that steaming and the fermentation process could significantly improve the cognitive-enhancement and neuroprotective effects of Codonopsis lanceolata, the anti-tumor efficacy of steamed C. lanceolata (SCL) and what mechanisms are involved remain largely unknown. The present study was designed to evaluate the anti-tumor effect in vivo of SCL in H22 tumor-bearing mice. The results clearly indicated that SCL could not only inhibit the tumor growth, but also prolong the survival time of H22 tumor-bearing mice. Besides, the serum levels of cytokines, such as interferon gamma (IFN-γ), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-2 (IL-2), were enhanced by SCL administration. The observations of Hoechst 33258 staining demonstrated that SCL was able to induce tumor cell apoptosis. Finally, immunohistochemical analysis revealed that SCL treatment significantly increased Bax expression and decreased Bcl-2 and vascular endothelial growth factor (VEGF) expression of H22 tumor tissues in a dose-dependent manner. Moreover, LC/MS analysis of SCL indicated that it mainly contained lobetyolin and six saponins. Taken all together, the findings in the present study clearly demonstrated that SCL inhibited the H22 tumor growth in vivo at least partly via improving the immune functions, inducing apoptosis and inhibiting angiogenesis.

Abstract
The present study evaluated the anti-diabetic effects of the polysaccharides obtained from Talinum triangulare (TTP). Two TTP doses (150 mg/kg and 300 mg/kg · bw/d) were administered orally to normal and streptozotocin (STZ)-induced type 2 diabetic male Kunming mice, respectively. The TTP hypoglycemic and hypolipidemic effects were evaluated by testing the fast blood glucose (FBG) level, fasting serum insulin (FINS), and serum lipids (TC, TG, HDL, LDL) as well as the body, hepar and kidney weights. After four weeks administration, the low-dose group 150 mg/kg · bw/d) and high-dose group (300 mg/kg · bw/d) showed a marked FBG fall rate of 29.85% and 41.18% (FBG fall rate% = ((Diabetic control--TTP group)/Diabetic control) × 100%). The results of FBG and serum lipids indicate that TTP possess significant hypoglycemic effect, but no significant hypolipidemic effect. These results suggest the potential use of TTP as a functional food for the treatment of type 2 diabetic mellitus (T2DM).
