Yao W, Liu M, Chen X, You L, Ma Y, Hileuskaya K. Effects of UV/H 2O 2 degradation and step gradient ethanol precipitation on Sargassum fusiforme polysaccharides: Physicochemical characterization and protective effects against intestinal epithelial injury. Food Res Int 2022; 155:111093. [PMID: 35400466 DOI: 10.1016/j.foodres.2022.111093] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2021] [Revised: 03/01/2022] [Accepted: 03/02/2022] [Indexed: 11/18/2022]
Abstract
In this study, the degraded purified fraction from Sargassum fusiforme polysaccharides (SFP), named DSFP, was produced by the treatment of ultraviolet/hydrogen peroxide (UV/H2O2) degradation and step gradient ethanol precipitation. Results showed that the treatment significantly reduced the molecular weight of polysaccharides, from 282.83 kDa to 18.54 kDa, and influenced their surface morphology and roughness. SFP and DSFP were typical sulfated polysaccharides, mainly composed of fucose, galacturonic acid, glucuronic acid, galactose, and mannose. Both SFP and DSFP increased cell migration during intestinal epithelial wound healing and stimulated the cell cycle progression by promoting the transition from G0/G1 to S phase in the rat intestine epithelium cells (IEC-6). But DSFP had a stronger positive effect on wound healing and cell migration than SFP. It reinforced the intestinal barrier function and attenuated lipopolysaccharides-induced intestinal inflammation. DSFP significantly downregulated the expression of Toll-like receptor 4, tumor necrosis factor-α, interleukin-6, interleukin-1β, and inducible nitric oxide synthase by 53.14%, 92.41%, 66.01%, 68.24%, and 78.09%, respectively, and upregulated that of interleukin-10 by 2.48 folds when compared to the model. Therefore, the treatment (UV/H2O2 degradation and step gradient ethanol precipitation) could effectively improve the protective effects against intestinal epithelial injury.

Structure of water-soluble polysaccharides in spore of Ganoderma lucidum and their anti-inflammatory activity. Food Chem 2022; 373:131374.

Abstract
Ganoderma lucidum spore is widely accepted as functional food. Polysaccharides are the predominant bioactive components in G. lucidum spore and contribute much to its health benefits. However, their structural characteristics remain unclear. In this work, water-soluble polysaccharides (GLSP) were obtained by hot water extraction. Three monosaccharides, including arabinose (Ara), glucose (Glc) and galactose (Gal), were presented in GLSP. 1D and 2D NMR data revealed that GLSP were composed mainly by two polysaccharides, β-glucan and arabinogalactan. The arabinogalactan had a backbone of galactan with Araf in the side chain. β-Glucan was the dominant polysaccharide in G. lucidum spore. The molecular weight was measured. GLSP could induce IEC-6 cells proliferation in a concentration-dependent manner. Moreover, GLSP possessed a strong anti-inflammatory activity through inhibiting the overproduction of NO and pro-inflammatory cytokines, like interleukin-6 (IL-6) and interleukin-1β (IL-1β) induced by LPS. These results implied the potential of GLSP on gut barrier protection.

Abstract
Polysaccharides are the most abundant bioactive compounds in Ganoderma and have been widely used as dietary supplements in traditional Chinese medicine for thousands of years. Polysaccharides from Ganoderma exhibit unique biological properties, including anti-tumor, anti-inflammatory, and immunomodulatory activities. Herein, the sources and structures of polysaccharides from Ganoderma were presented. This work also reviews the immunomodulatory activities and possible mechanisms of polysaccharides from Ganoderma on different immune effector cells, including lymphocytes and myeloid cells. As an available adjunctive remedy, polysaccharides from Ganoderma can potentially be applied for the modulation of the host immune system, namely the innate immunity, the cellular immunity, and the humoral immunity.

Abstract
FoxM1 is involved in the regeneration of several organs after injury and expressed in the intestinal mucosa. The intrinsic mechanism of FoxM1 activity in the mucosa after intestinal ischemia/reperfusion (I/R) injury has not been reported. Therefore, we investigated the role of FoxM1 in mediating intestinal mucosa regeneration after I/R injury. Expression of FoxM1 and the proliferation of intestinal mucosa epithelial cells were examined in rats with intestinal I/R injury and an IEC-6 cell hypoxia/reperfusion (H/R) model. The effects of FoxM1 inhibition or activation on intestinal epithelial cell proliferation were measured. FoxM1 expression was consistent with the proliferation of intestinal epithelial cells in the intestinal mucosa after I/R injury. Inhibition of FoxM1 expression led to the downregulation of Ki-67 expression mediated by the inhibited expression of Nurr1, and FoxM1 overexpression promoted IEC-6 cell proliferation after H/R injury through activating Nurr1 expression. Furthermore, FoxM1 directly promoted the transcription of Nurr1 by directly binding the promoter of Nurr1. Further investigation showed low expression levels of FoxM1, Nurr1, and Ki-67 in the intestinal epithelium of patients with intestinal ischemic injury. FoxM1 acts as a critical regulator of intestinal regeneration after I/R injury by directly promoting the transcription of Nurr1. The FoxM1/Nurr1 signaling pathway represents a promising therapeutic target for intestinal I/R injury and related clinical diseases. A signaling pathway that promotes the regeneration of intestinal cells in rats represents a promising therapeutic target for treating intestinal injury in humans. A team led by Guo Zu and Jing Guo from Dalian Medical University in China investigated the role of a regulatory protein called FoxM1 in repairing intestinal damage after a period of inadequate blood flow to the tissues of the gastrointestinal tract. They showed in rat models that FoxM1 promoted the proliferation of intestinal cells after injury by activating other proteins in a particular signaling pathway. Looking at tissue samples from five people who experienced intestinal injury as a result of restricted blood flow, the researchers detected low expression levels of FoxM1 and its downstream signaling intermediaries. Boosting the activity of those proteins could help promote healing and regeneration.

Abstract
The Ganoderma lucidum (G. lucidum) mushroom is one of the most extensively studied functional foods, known for its numerous health benefits, including the inhibition of tumor cell growth. The present study assessed the anti-proliferative and pro-apoptotic activity of a novel G. lucidum polysaccharide peptide (GL-PP) in human glioma U251 cells, which was purified from grass-cultured G. lucidum. GL-PP is a glycopeptide with an average molecular weight of 42,635 Da and a polysaccharide-to-peptide ratio of 88.70:11.30. The polysaccharides were composed of l-arabinose, d-mannose and d-glucose at a molar ratio of 1.329:0.372:2.953 and a total of 17 amino acids were detected. The results of the current study demonstrated that GL-PP significantly inhibited U251 cellular proliferation. The proportion of G0/G1 phase cells and sub-G1 phase cells significantly increased as the concentration of GL-PP increased, as did the activity of caspase-3. These results indicate that GL-PP directly inhibited human glioma U251 proliferation by inducing cell cycle arrest and promoting apoptosis.

Abstract
Corneal chemical burns are common ophthalmic injuries that may result in permanent visual impairment. Although significant advances have been achieved on the treatment of such cases, the structural and functional restoration of a chemical burn-injured cornea remains challenging. The applications of polysaccharide hydrogel and subconjunctival injection of mesenchymal stem cells (MSCs) have been reported to promote the healing of corneal wounds. In this study, polysaccharide was extracted from Hardy Orchid and mesenchymal stem cells (MSCs) were derived from Sprague-Dawley rats. Supplementation of the polysaccharide significantly enhanced the migration rate of primarily cultured rat corneal epithelial cells. We examined the therapeutic effects of polysaccharide in conjunction with MSCs application on the healing of corneal alkali burns in rats. Compared with either treatment alone, the combination strategy resulted in significantly better recovery of corneal epithelium and reduction in inflammation, neovascularization and opacity of healed cornea. Polysaccharide and MSCs acted additively to increase the expression of anti-inflammatory cytokine (TGF-β), antiangiogenic cytokine (TSP-1) and decrease those promoting inflammation (TNF-α), chemotaxis (MIP-1α and MCP-1) and angiogenesis (VEGF and MMP-2). This study provided evidence that Hardy Orchid derived polysaccharide and MSCs are safe and effective treatments for corneal alkali burns and that their benefits are additive when used in combination. We concluded that combination therapy with polysaccharide and MSCs is a promising clinical treatment for corneal alkali burns and may be applicable for other types of corneal disorder.

Abstract
This study explored the feasibility of preparing nano/submicrometer particles from Ganoderma tsugae to enhance the contents of bioactive compounds and to assess its mutagenic potencies and cytotoxicity. Hot-water extract, a common product, was employed as a reference. After 3 h of media milling, almost all of the particles were smaller than 1 μm with a number-mean diameter of 0.11 μm. There were about 62% particles smaller than 0.1 μm in terms of number of particles. Scanning electron microscopy (SEM) confirmed the presence of particles at nano/submicrometer scale. The content of 1→3-β-D-glucan in nano/submicrometer G. tsugae was 3.5 times of that in hot-water extract. Both nano/submicrometer and hot-water extract G. tsugae exhibited no mutagenic potential to Salmonella Typhimurium tester strains. Cell toxicity test also confirmed the safety of both nano/submicrometer and hot-water extract G. tsugae. The effect of media milling on the structural change of hyphae was also discussed.

Abstract
Ganoderma lucidum (M.A. Curtis:Fr.) P. Karst is a popular medicinal mushroom. Scientific reports had shown that the wound healing effects of G. lucidum were partly attributed to its rich polysaccharides. However, little attention has been paid to its potential effects on wounds associated with diabetes mellitus. In this study, we evaluated the wound healing activity of the hot aqueous extract of G. lucidum in streptozotocin-induced diabetic rats. The extract of G. lucidum was standardised based on chemical contents (w/w) of total polysaccharides (25.1%), ganoderic acid A (0.45%), and adenosine (0.069%). Six groups of six rats were experimentally wounded in the posterior neck region. Intrasite gel was used as a positive control and aqueous cream as the placebo. Topical application with 10% (w/w) of mushroom extract-incorporated aqueous cream was more effective than that with Intrasite gel in terms of wound closure. The antioxidant activity in serum of rats treated with aqueous extract of G. lucidum was significantly higher; whereas the oxidative protein products and lipid damage were lower when compared to those of the controls. These findings strongly support the beneficial effects of standardised aqueous extract of G. lucidum in accelerating wound healing in streptozotocin-induced diabetic rats.

Abstract
Oral mucositis is one of the common side effects of chemotherapy treatment with potentially severe implications. Despite several treatment approaches by conventional and complementary western medicine, the therapeutic outcome is often not satisfactory. Traditional Chinese Medicine (TCM) offers empirical herbal formulas for the treatment of oral ulceration which are used in adaptation to chemotherapy-induced mucositis. While standard concepts for TCM treatment do not exist and acceptance by conventional oncologists is still low, we conducted a review to examine the evidence of Chinese herbal treatment in oral mucositis. Eighteen relevant studies on 4 single herbs, 2 combinations of 2 herbs, and 11 multiherbal prescriptions involving 3 or more compounds were included. Corresponding molecular mechanisms were investigated. The knowledge about detailed herbal mechanisms, especially in multi-herbal prescriptions is still limited. The quality of clinical trials needs further improvement. Meta-analysis on the existent database is not possible but molecular findings on Chinese medicinal herbs indicate that further research is still promising for the treatment of chemotherapy-induced oral mucositis.

Abstract
Immune responses to tumor-associated antigens are often detectable in tumor-bearing hosts, but they fail to eliminate malignant cells or prevent development of metastases. Tumor cells produce factors such as interleukin-10, transforming growth factor-β1 and vascular endothelial growth factor (VEGF) that suppress the function of immune cells or induce apoptosis of immune cells. Culture supernatant of tumor cells may contain these immunosuppressive factors which suppress lymphocyte activation. CD71 and FasL are two important molecules that are expressed upon lymphocyte activation. Counteraction against suppression CD71 and FasL expression upon lymphocyte activation may benefit tumor control. A potential component with this effect is Ganoderma lucidum polysaccharides (Gl-PS). In this study, Gl-PS was used on lymphocytes incubating with culture supernatant of B16F10 melanoma cells (B16F10-CS) in the presence of phytohemagglutinin. Following induction with phytohemagglutinin, B16F10-CS suppressed CD71 expression in lymphocytes (as detected by immunofluorescence and flow cytometry), proliferation in lymphocytes (as detected by MTT assay), and FasL expression in lymphocytes (as detected by immunocytochemistry and western blot analysis), while Gl-PS fully or partially counteracted these suppressions. Gl-PS showed counteractive effects against suppression induced by B16F10-CS on CD71 and FasL expression upon lymphocyte activation, suggesting the potential of Gl-PS to facilitate cancer immunotherapy.
