Guo W, Yun J, Wang B, Xu S, Ye C, Wang X, Qu Y, Zhao F, Yao L. Comparative study on physicochemical properties and hypoglycemic activities of intracellular and extracellular polysaccharides from submerged fermentation of Morchella esculenta. Int J Biol Macromol 2024; 278:134759. [PMID: 39151842 DOI: 10.1016/j.ijbiomac.2024.134759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 07/01/2024] [Accepted: 08/13/2024] [Indexed: 08/19/2024]
Abstract
The structural characteristic, physicochemical properties and structure-hypoglycemic activity relationship of intracellular (IPS) and extracellular (EPS) from submerged fermentation of Morchella esculenta were systematically compared and assessed. Both IPS and EPS were neutral, with a triple-helical conformation, and composed of galactose, glucose and mannose monosaccharides in different molar ratios. The molecular weight and particle size of IPS were higher than those of EPS. FTIR and SEM showed that the main functional group absorption peak intensity, glycosidic bond type and surface morphology of the two polysaccharides differed. Analysis of rheological and thermal properties revealed that the viscosity of IPS was higher than that of EPS, while thermal stability of EPS was greater than that of IPS. Hypoglycemic activity analysis in vitro showed that both IPS and EPS were non-competitive inhibitors of α-amylase and α-glucosidase. EPS showed strong digestive enzyme inhibitory activity due to its higher sulphate content and molar ratio of galactose, lower Mw and particle size. Meanwhile, with its higher Mw and apparent viscosity, IPS showed stronger glucose adsorption capacity and glucose diffusion retardation. These results indicate that IPS and EPS differed considerably in structure and physicochemical properties, which ultimately led to differences in hypoglycemic activity. These results not only suggested that IPS and EPS has the potential to be functional foods or hypoglycemic drugs, but also provided a new target for the prevention and treatment of diabetes with natural polysaccharides.

Shiitake polysaccharides acted as a non-competitive inhibitor to α-glucosidase and inhibited glucose transport of digested starch from Caco-2 cells monolayer. Food Res Int 2023; 173:113268. [PMID: 37803584 DOI: 10.1016/j.foodres.2023.113268] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 07/09/2023] [Accepted: 07/11/2023] [Indexed: 10/08/2023]
Abstract
The inhibition mechanism of shitake mushroom polysaccharides (Lentinula edodes polysaccharides, LEP) against α-glucosidase was studied by enzyme kinetic assay, fluorescence quenching and molecular docking. The effect of LEP on glucose transport of digested starch was investigated via an in vitro digestion/Caco-2 transwell model. LEP exhibited a stronger inhibiting effect (IC50 = 0.66 mg/mL) than acarbose and presented a non-competitive inhibition mechanism. The interaction between LEP and α-glucosidase primarily involved electrostatic interaction and hydrogen bonding. Molecular docking modelling showed that the four structures of LEP were bound to the allosteric tunnel or adjacent pocket of α-glucosidase via electrostatic force and hydrogen bonds. The (1 → 6)-linkages in LEP structures favoured its binding affinity to the α-glucosidase. The α-glucosidase inhibiting activity of LEP was also found to emanate from the reduction in glucose transport of digested starch as deducted from the in vitro digestion/Caco-2 transwell data. The release of glucose from digested starch cooked with LEP was significantly reduced (33.7%) compared to the digested starch without LEP. The findings from the current study suggest that LEP could be a promising ingredient to inhibit α-glucosidase activity as well as control the level of postprandial blood glucose when incorporated into starchy foods.

Extraction and characterization of polysaccharide from fermented mycelia of Coriolus versicolor and its efficacy for treating nonalcoholic fatty liver disease. Int J Biol Macromol 2023; 248:125951. [PMID: 37499724 DOI: 10.1016/j.ijbiomac.2023.125951] [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: 01/16/2023] [Revised: 07/09/2023] [Accepted: 07/21/2023] [Indexed: 07/29/2023]
Abstract
Coriolus versicolor, a popular traditional Chinese medicinal herb, is widely used in China to treat spleen and liver diseases; however, the beneficial effects of C. versicolor polysaccharides (CVPs) on nonalcoholic fatty liver disease (NAFLD) remain elusive. Herein we isolated and purified a novel CVP (molecular weight, 17,478 Da) from fermented mycelium powder. This CVP was composed of mannose, galacturonic acid, glucose, galactose, xylose, and fucose at a molar ratio of 22:1:8:15:10:3. Methylation, gas chromatography-mass spectrometry, and nuclear magnetic resonance analyses indicated that the CVP backbone consisted of →1)-β-D-Man-(6,4→1)-α-D-Gal-(3→1)-α-D-Man-(4→1)-α-D-Gal-(6→, with branches of →1)-α-D-Glc-(6→1)-α-D-Man-(4,3→1)-β-D-Xyl-(2→1)-β-D-Glc on the O-6 position of →1)-β-D-Man-(6,4→ of the main chain. The secondary branches linked to the O-4 position of →1)-α-D-Man-(4,3→ with the chain of →1)-α-D-Fuc-(4→1)-α-D-Man. Further, CVP treatment alleviated the symptoms of NAFLD in an HFD-induced mice model. CVP altered gut microbiota, predominantly suppressing microbes associated with bile acids both in the serum and cecal contents. In vitro data showed that CVP reduced HFD-induced hyperlipidemia via farnesoid X receptor. Our results improve our understanding of the mechanisms underlying the cholesterol- and lipid-lowering effects of CVP and indicate that CVP is a promising candidate for NAFLD therapy.

Abstract
In this study, two extracellular polysaccharides (TEPS1 and TEPS2) were isolated from the endophytic fungus (Talaromyces purpureogenus) and purified by DEAE-Sepharose Fast Flow column using NaCl as gradient eluent. The HPLC analysis displayed that TEPS1 was composed of mannose (38.70%), ribose (25.02%), glucose (19.34%), and galactose (16.94%) while the TEPS2 composed by mannose (100%). The NMR results indicated that TEPS1 exhibited α-glycosidic configurations. The both polysaccharides, TEPS1 and TEPS2 were exhibited a good antioxidant activity in terms of DPPH, ABTS, and •OH scavenging. However, TEPS1 showed a higher antioxidant activity than TEPS2. The IC50 of TEPS1 were 32.16, 192.57, and 54.67 μg·mL-1, for DPPH, ABTS, and •OH radical scavenging, respectively. Furthermore, TEPS1 showed the high cellular antioxidant and wound healing activity in the human embryonic kidney (HEK293) cell line. Overall, these two polysaccharides were promising in antioxidant activity.

Abstract
The aim of this study is to characterize the bioactivity of mycelial biomass and crude exopolysaccharides (EPS) produced by Trametes versicolor NBIMCC 8939 and to reveal its nutraceutical potential. The EPS (1.58 g/L) were isolated from a culture broth. The macrofungal biomass was rich in protein, insoluble dietary fibers and glucans. The amino acid composition of the biomass was analyzed and 18 amino acids were detected. Three mycelial biomass extracts were prepared and the highest total polyphenol content (16.11 ± 0.14 mg GAE/g DW) and the total flavonoid content (5.15 ± 0.03 mg QE/g DW) were found in the water extract. The results indicated that the obtained EPS were heteropolysaccharides with glucose as the main building monosaccharide and minor amounts of mannose, xylose, galactose, fucose and glucuronic acid. Fourier Transform Infrared Spectroscopy (FTIR) confirmed the complex structure of the crude EPS. Five probiotic lactic acid bacteria strains were used for the determination of the prebiotic effect of the crude EPS. The anti-inflammatory potential was tested in vitro using cell line HT-29. The significant decrease of IL-1 and IL-8 and increase of TGF-beta expression revealed anti-inflammatory potential of the crude exopolysaccharides from T. versicolor.

Abstract
A novel polysaccharide, Heimioporus retisporus Polysaccharide (HRP) was extracted from the edible mushroom Heimioporus retisporus. HRP had weight-average molecular weight 1,949 kDa and number-average molecular weight 873 kDa, and its major components were arabinose (0.71%), galactose (12.93%), glucose (49.00%), xylose (8.59%), mannose (17.78%), and glucuronic acid (10.99%). Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy revealed that HRP was composed of 1,3-linked β-D-glucose, 1,6-linked β-D-mannose, 1,6-linked β-D-galactose, 1,4-linked β-D-galactose, 1,4-linked β-D-xylose, and 1,5-linked α-L-arabinose. Thermogravimetric analysis indicated that degradation temperature (T0) of HRP was 200°C. In an STZ-induced diabetic mouse model, oral administration of HRP (40 mg/kg/d) for 28 days significantly reduced blood glucose levels, and reduced heart organ index by decreasing expression of IL-6 and TNF-α. Our findings indicate hypoglycemic effect of HRP, and its potential application as a hypoglycemic agent.

Abstract
A new polysaccharide (AABP-2B) was obtained from Anemarrhena asphodeloides Bunge after purification by gradient alcohol precipitation and DEAE-52 cellulose column chromatography. AABP-2B was confirmed to be a homogeneous polysaccharide with a molecular weight of 5800 Da and was composed of mannose and glucose at a molar ratio of 7.2 : 2.8. Structural analysis demonstrated that the backbone of AABP-2B was mainly composed of 4)-β-D-Manp-(1, 4,6)-β-D-Glcp-(1 and 3,6)-β-D-Manp-(1. The hypoglycaemic effect of AABP-2B was evaluated by its inhibition of α-glucosidase activities and insulin resistance in a HepG2 cell model. The results showed that AABP-2B displayed α-glucosidase inhibitory activities and could significantly improve glucose consumption by activating the IRS-1/PI3K/Akt signalling pathway in insulin-resistant HepG2 cells. Hence, AABP-2B may have potential as a functional food or medicine for diabetes therapy.

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
Metabolic syndrome is an aggregation of conditions and associated with an increased risk of developing
diabetes, obesity and cardiovascular diseases (CVD). Edible mushrooms are widely consumed in many countries
and are valuable components of the diet because of their attractive taste, aroma, and nutritional value. Medicinal
mushrooms are higher fungi with additional nutraceutical attributes having low-fat content and a transisomer
of unsaturated fatty acids along with high fiber content, biologically active compounds such as polysaccharides
or polysaccharide β-glucans, alkaloids, steroids, polyphenols and terpenoids. In vitro experiments, animal
models, and even human studies have demonstrated not only fresh edible mushroom but also mushroom
extract that has great therapeutic applications in human health as they possess many properties such as antiobesity,
cardioprotective and anti-diabetic effect. They are considered as the unmatched source of healthy foods
and drugs. The focus of this report was to provide a concise and complete review of the novel medicinal properties
of fresh or dry mushroom and extracts, fruiting body or mycelium and its extracts, fiber, polysaccharides,
beta-glucan, triterpenes, fucoidan, ergothioneine from edible mushrooms that may help to prevent or treat metabolic
syndrome and associated diseases.

Abstract
Medicinal mushrooms are higher fungi with additional nutraceutical attributes having low fat content and a trans-isomer of unsaturated fatty acids along with high fibre content, triterpenes, phenolic compounds, sterols, eritadenine and chitosan. They are considered as the unmatched source of healthy foods and drugs. They have outstanding attractive taste, aroma and nutritional value, so are considered as functional food, which means they are beneficial to the body not only in terms of nutrition but also for improved health. Medicinal mushrooms and their extract have a large number of bioactive components called secondary metabolites. The presence of polysaccharide β-glucans or polysaccharide-protein complexes content in mushroom extract have great therapeutic applications in human health as they possess many properties such as anti-diabetic, anti-cancerous, anti-obesity, immunomodulatory, hypocholesteremia, hepatoprotective nature along with anti-aging. The present review focuses on the comprehensive account of the medicinal properties of various medicinal mushrooms. This will further help the researchers to understand the metabolites and find other metabolites as well from the mushrooms which can be used for the potential development of the drugs to treat various life-threatening diseases.

Potential activities and mechanisms of extracellular polysaccharopeptides from fermented Trametes versicolor on regulating glucose homeostasis in insulin-resistant HepG2 cells.

Abstract
Polysaccharides derived from mushrooms have potential to control blood sugar, reduce insulin resistance and prevent diabetic complications. The intracellular polysaccharopeptides of Trametes versicolor (TV) have been used as immunologic and oncologic adjuvants. The aim of this study was to investigate the potential activities and mechanisms of extracellular polysaccharopeptides (ePSP) obtained from TV strain LH-1 on regulating glucose homeostasis. Human hepatoma HepG2 cells incubated with normal glucose (5.5 mM, NG model), high glucose (33 mM, HG model), or high glucose (33 mM) plus high insulin (10−7 M, HGI model) concentrations were administered with TV LH-1 ePSP (50, 100, and 1000 μg/ml) for 24 hr. Glucose uptake of HepG2 cells, determined by flow cytometry, was significantly decreased in the HG and HGI models with insulin stimulation, suggesting insulin resistance of these cells; however, ePSP reversed this decrease in a dose-dependent manner (one-way ANOVA, p<0.05). In the HG and HGI models, ePSP significantly increased glycogen content, insulin receptor substrate-2 protein and phosphorylated AMP-activated protein kinase (AMPK), as determined by western blot analysis. In addition, ePSP significantly increased glucokinase in the NG and HG models, increased membrane glucose transporter-1 and decreased glycogen synthase kinase-3β in the HGI model, and increased glucose-6-phosphatase in the NG and HGI models (one-way ANOVA, p<0.05). In summary, TV LH-1 ePSP may elevate cellular glucose uptake to regulate glucose homeostasis via the activation of AMPK and glycogen synthesis in an insulin-independent manner. These results suggest that TV LH-1 ePSP may be a nutraceutical with anti-hyperglycemic activity.

Abstract
The rhizoma of Dioscorea hemsleyi (DH) has been used as a treatment of diabetes in China for hundreds of years. Polysaccharides in DH were extracted by using ultrasonic-assisted extraction (UAE), cold water extraction (CWE), warm water extraction (WWE) and hot water extraction (HWE), separately. Then the different characterizations of four DH polysaccharide (DHP) samples were analyzed by high-performance liquid chromatography (HPLC), high-performance Gel permeation chromatography (HGPC), ultraviolet-visible spectroscopy(UV), fourier transform-infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). Their activities in vitro of DHP were compared. Experimental results showed that HWE had the highest yield and large molecular weight. CWE had the highest uronic acid yield and little molecular weight, and its DPPH, AGI and AAI activity were the best. The molecular weight of UAE was small, and its RP and FRAP activity were the best. Four DHP samples had differences in the surface topography, while they all had the typical IR spectra characteristic of polysaccharides. According the correlation analysis, it showed that the more uronic acid and the lower molecular weight was, the higher the antioxidant activity was. The high content of monosaccharide composition of Xyl, Ara, GlcA and GalA, and little molecular weight have good effect on antidiabetic activity.

Abstract
In this study, the binding of a glycosylated serine protease (EuP-82) with human fibrinogen was investigated by isothermal titration calorimetry (ITC). ITC analysis indicated that the binding of EuP-82 to fibrinogen in the conditions with or without the activator (Ca2+ ) was an exothermic reaction (dominant negative enthalpy), which tended to be driven by hydrogen bonding and van der Waals interactions. In contrast, the binding of fibrinogen-EuP-82 in the condition with the inhibitor (Zn2+ ) was an unfavorable endothermic reaction. EuP-82 could not inhibit the platelet activity in citrated whole blood via the ADP-receptor pathways (mainly, P2Y1 and P2Y12), but it could enhance the platelet aggregation. The ITC together with whole blood platelet aggregation suggested that EuP-82 provided multiple fibrinogen-binding sites that were not related to the arginine-glycine-aspartate (RGD) and the dodecapeptide sequences of fibrinogen. In addition, EuP-82 had neither thrombin-like activity nor anticoagulant activity. The SR-FTIR spectra revealed that EuP-82 was a glycoprotein. Deglycosylation of EuP-82 did not affect its proteolytic activity. Moreover, EuP-82 did not exhibit any toxicity to the living cells (NIH-3T3). This study supports that EuP-82 may be useful for wound-healing material through stabilizing the clot via the platelet induction for the first process.

Abstract
Diabetes mellitus (DM) is a metabolic disease attracted worldwide concerns, which severely impairs peoples' quality of life and is attributed to several life-threatening complications, including atherosclerosis, nephropathy and retinopathy. The current therapies for DM include mainly oral anti-diabetic drugs and insulin. However, continuous use of these causes insulin resistance and side-effects, and the demand of effective, nontoxic and affordable drugs for DM patients is eager. Several previous studies have shown that non-toxic biological macromolecules, mainly polysaccharides, possess prominent efficacies on DM. Based on these encouraging observations, a great deal of efforts have been focused on discovering anti-diabetic polysaccharides for the development of effective therapeutics for DM. This review focuses on the advancements in the anti-diabetic efficacy of various natural polysaccharides and polysaccharide complexes from 2010 to 2015.

Abstract
This study investigates the effects of Trametes versicolor (L.:Fr.) Pilát (TVP, also known as Yunzhi) on bone properties in diabetic rats. Forty-five male Wistar rats (8 weeks old) were fed either a chow diet (control) or a high-fat diet throughout the study period of 28 days. Animals in the high-fat-diet group were injected with nicotinamide and streptozotocin to induce diabetes mellitus (DM). The DM rats were divided into a group receiving distilled water (vehicle) and another group receiving TVP at 0.1 g/kg weight by gavage. Relative to the vehicle group, TVP gavage lowered postprandial blood sugar (225 ± 18 mg/dL for TVP vs 292 ± 15 mg/dL for vehicle, p < 0.001) on day 26. Compared to the vehicle group, TVP mitigated DM-induced bone deterioration as determined by increasing bone volume of proximal tibia (22.8 ± 1.4% for TVP vs 16.8 ± 1.3% for vehicle, p = 0.003), trabecular number (p = 0.011), and femoral bone strength (11% in maximal load, 22% in stiffness, 14% in modulus, p < 0.001), and by reducing loss of femoral cortical porosity by 25% (p < 0.001). Our study demonstrates the protective effect of TVP on bone properties was mediated through, in part, the improvement of hyperglycemic control in DM animals.

Abstract
Acetylcholinesterase (AChE) inhibition enhances learning and cognitive ability for treatment of Alzheimer’s disease. Polysaccharide–peptide complexes were identified in Cordyceps militaris (CPSPs) and characterized for their AChE inhibitory properties. Three polymers (CPSP-F1, -F2, and -F3) were extracted and separated by ultrasound-assisted extraction and dieth-ylaminoethanol (DEAE)–Sepharose CL-6B column chromatography. Polysaccharide–peptide complexes were identified by DEAE–Sepharose CL-6B column chromatography and high-performance gel-filtration chromatography, Fourier transform infrared spectra, amino sugar composition analysis, and β-elimination reaction to identify polysaccharide–peptide bond categories. Separation of CPSP can increase AChE inhibitory activity from the crude poly-saccharide of C. militaris. CPSP-F1 and CPSP-F2 exhibited half maximal inhibitory concentrations of 32.2 ± 0.2 mg/mL and 5.3 ± 0.0 mg/mL. Thus, we identified polysaccharide–peptide complexes from C. militaris and suggest CPSP has great potential in AChE inhibition bioassay.
