Abstract
Laminaria japonica, one of the most widespread seafood consumed in China and many other nations, has been traditionally utilized as an effective therapeutically active substance for treating weight loss, phlegm elimination, and detumescence for more than 2000 years. Numerous studies have found that the polysaccharides play an indispensable role in the nutritional and medicinal value of L. japonica. Water extraction and alcohol precipitation method is the most used method. Approximately 56 LJPs were successfully isolated and purified from L. japonica, whereas only few of them were well characterized. Modern pharmacological studies have shown that L. japonica polysaccharides (LJPs) have high-order structural features and multiple biological activities, including anti-tumor, anti-thrombotic, anti-atherosclerosis, hypolipidemic, hypoglycemic, antioxidant, anti-inflammatory, renoprotective, and immunomodulatory. In addition, the structural characteristics of LJPs are closely related to their biological activity. In this review, the extraction and purification methods, structural characteristics, biological activities, clinical settings, toxicities, and structure-activity relationships of LJPs are comprehensively summarized. The structural characteristics and biological activities as well as the underlying molecular mechanisms of LJPs were also outlined. Furthermore, the clinical settings and structure-activity functions of LJPs were highlighted. Some research perspectives and challenges in the study of LJPs were also proposed.

[PMID: 32630038 PMCID: PMC7400497 DOI: 10.3390/nu12071958] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 06/26/2020] [Accepted: 06/27/2020] [Indexed: 12/21/2022] Open
Abstract
Continuous exposure to ultraviolet B (UVB) can cause photodamage of the skin. This photodamage can be inhibited by the overexpression of the non-coding RNA, nc886, via the protein kinase RNA-activated (PKR) pathway. The study aims to identify how UVB inhibits nc886 expression, and it also seeks to determine whether substances that can control nc886 expression can influence UV-induced inflammation, and the mechanisms involved. The results suggest that UVB irradiation accelerates the methylation of the nc886 gene, therefore, reducing its expression. This induces the activation of the PKR, which accelerates the expression of metalloproteinase-9 (MMP-9) and cyclooxygenase (COX-2), and the production of MMP-9, prostaglandin-endoperoxide synthase (PGE2), and certain pro-inflammatory cytokines, specifically interleukin-8 (IL-8), and tumor necrosis factor- (TNF-). Conversely, in a model of nc886 overexpression, the expression and production of those inflammatory factors are inhibited. In addition, Laminaria japonica extract (LJE) protect the levels of nc886 against UVB irradiation then subsequently inhibit the production of UV-induced inflammatory factors through the PKR pathway.

J Food Biochem 2019; 43:e12850. [PMID: 31353709 DOI: 10.1111/jfbc.12850] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2018] [Revised: 02/14/2019] [Accepted: 03/08/2019] [Indexed: 01/18/2023]
Abstract
The present study aimed to investigate, in in vitro assays, the antilipogenic and antiinflammatory potential as well as the antioxidant capacity of biotransformed soymilk by tannase and β-glycosidase enzymes. The results showed a significant enhancement of the antioxidant capacity, especially by biotransformed soymilk with free tannase (SFT), corresponding to an increase of 2.3 and 1.25 times by oxygen radical absorbance capacity (ORAC) and ferric reducing antioxidant power (FRAP) assays, respectively. The lipid accumulation reduction by 3T3-L1 adipocytes assay was not significant. However, the antiinflammatory responses were expressive. In lipopolysaccharide-stimulated RAW 264.7 macrophages, SFT reduced around 37 times TNF-α expression at the highest tested concentration of the sample. Other inflammatory parameters, as IL-6 and nitric oxide, were no longer detected when the cells were treated with SFT and soymilk with immobilized enzymes, respectively. The biotransformed soy extracts with tannase have great potential to act as a nutraceutical, protecting the cells against oxidative damage and helping maintain health under inflammatory stress. PRACTICAL APPLICATIONS: Soy isoflavones have been associated with several beneficial effects on human health, including inhibition capacity of lipid accumulation in adipocytes, antiinflammatory properties, and antioxidant potential. However, the isoflavones bioavailability differs among their chemical forms, and studies have shown that the higher health benefits are conferred by aglycones and their metabolites, such as equol, compared to the other forms. For this reason, the enrichment of isoflavone aglycones and metabolites in soy-based products has attracted growing attention. The present study was focused on developing a bioprocess able to produce a rich extract with soy isoflavones metabolites, with increased bioactive potential for application as a functional ingredient or a nutraceutical.

Abstract
Glucans are a group of glucose polymers that are found in bacteria, algae, fungi, and plants. While their properties are well known, their biochemical and solubility characteristics vary considerably, and glucans obtained from different sources can have different applications. Research has described the bioactivity of β-glucans extracted from the algae of the Laminaria genus, including in vivo and in vitro studies assessing pro- and anti-inflammatory cytokines, vaccine production, inhibition of cell proliferation, and anti- and pro-oxidant activity. Thus, the objective of this article was to review the potential application of β-glucans from Laminaria spp. in terms of their immunomodulatory properties, microorganism host interaction, anti-cancer activity and vaccine development.

Abstract
Soybean is one of the major components of the Japanese diet. In traditional Japanese cuisine, soybean-based food items are often consumed with brown algae. In this study, we examined the effect of water-soluble and fermentable polysaccharides, laminaran and sodium alginate, from brown algae, on putrefactive compound production, by human faecal microbiota in broth containing 3% (w/v) soy protein. We also investigated the effect of 2% laminaran or alginate diet on caecal putrefactive compounds in rats maintained on diets containing 20% (w/w) soy protein. The caecal microbiota was also analysed using denaturing gradient gel electrophoresis and pyrosequencing with primers targeting the bacterial 16S rRNA gene. The polysaccharides, particularly laminaran, inhibited ammonia, phenol, and indole production by human faecal microbiota. Both the algal polysaccharides lowered the caecal indole content. Laminaran was found to increase the number of Coprobacter, whereas Helicobacter was found to decrease in the presence of both laminaran and sodium alginate.

Abstract
Six lactic acid bacteria strains (four Lactobacillus plantarum strains and one each of Lactococcus lactis subsp. lactis and Pediococcus pentosaceus) have been isolated and shown to possess anti-oxidant activity. In this study, we determined their acid, bile, salt resistance, and adhesion activity on human enterocyte-like HT-29-Luc and Caco-2 cells. An isolate Lc. lactis S-SU2 showed highest bile resistance and adhesion activity compared to type strains. S-SU2 could ferment both 10% skimmed milk and soy milk while the type strain could not ferment soy milk. Soy milk fermented with S-SU2 showed an increased nitric oxide (NO) secretion in the mouse macrophage RAW264.7 cells without bacterial lipopolysaccharide (LPS). Furthermore, the inhibitory effects of the fermented soy milk on Escherichia coli O111 LPS-induced NO secretion were higher than those of fresh soy milk. Inflammatory bowel disease (IBD) was induced in mice fed either 5% (w/v) dextran sodium sulfate (DSS) in drinking water or 50% soy milk in drinking water. Shortening of colon length, breaking of epithelial cells, lowering liver and thymus weights, and enlargement of spleen are some of the characteristics observed in the IBD, which were prevented by the use of soy milk fermented with Lc. lactis S-SU2.

Abstract
The seaweed Laminaria japonica has been investigated in a laboratory research for its medical significance and LJP has been purified now. The objective of present study was to look at effect of LJP on structural, phenotypic and functional maturation of murine BMDCs. The structural maturation of BMDCs induced by LJP was evaluated by transmission electron microscopy (TEM); The phenotypic maturation of BMDCs was studied by flow cytometry(FCM) and functional maturation of BMDCs was analyzed by FITC-dextran, acid phosphatase (ACP) activity and enzyme linked immunosorbent assay (ELISA). We hereby proved that LJP markedly induced maturation of BMDCs with the data of decreased the number of lysosomes, upregulated expression of CD80, CD83, CD86, CD40 and MHC II key membrane molecules on BMDCs, downregulated phagocytosis, enriched production of IL-12 and TNF-α secreted by BMDCs. Therefore it should be concluded that LJP was with strong ability to induce maturation of BMDCs. Our data provided direct evidence to suggest that LJP could be considered as an immune stimulant in improving immune handicapped situation and as a useful adjuvant in vaccine designing.
