Abstract
SCOPE Manno-oligosaccharides from cassia seed gum (CMOS) have demonstrated anti-inflammatory and regulatory effects on cholesterol metabolism. However, their protective effects against the progression of atherosclerosis (AS) and underlying molecular mechanisms have not been investigated. This study investigates the anti-atherosclerotic effects of CMOS on ApoE-/- mice. METHODS AND RESULTS CMOS are supplemented in atherosclerotic male ApoE-/- mice fed with a high-fat-high-cholesterol diet (HFHCD). After the 12-week intervention, CMOS at 1200 mg kg-1 ·bw d-1 significantly decrease the atherosclerotic lesion area by 0.63-fold and the aortic arch lesion size by 0.63-fold when compared to the HFHCD group. Moreover, inflammation in atherosclerotic lesions is reduced by CMOS intervention, and the levels of serum lipids and inflammatory cytokines are decreased. The number of goblet cells and the expression of intestinal epithelial tight junction proteins in the H-CMOS group increase, thus indicating that CMOS can restore intestinal barrier integrity in atherosclerotic mice. Furthermore, CMOS reshape the unbalanced gut microbiota in ApoE-/- mice caused by HFHCD, and reduce the relative abundance of Desulfovibrio and Faecalibaculum that exhibits positive relationships with inflammation. CONCLUSION CMOS inhibit inflammation, alter intestinal barrier integrity, and regulate gut microbiota to attenuate AS in ApoE-/- mice.

Abstract
Coffee oligosaccharides (COS) are novel sources of prebiotics comprising manno-oligosaccharides, galacto-oligosaccharides, arabinoxylan-oligosaccharides, and cello-oligosaccharides. These oligosaccharides function as prebiotics, antioxidant-dietary fiber owing to important physicochemical and physiological properties, adjuvants, pharma, nutraceutical food, gut health, immune system boosting, cancer treatment, and many more. Research suggests COS performs prebiotic action, as it enhances gut health by promoting beneficial bacteria in the colon and releasing functional metabolites such as SCFAs. However, research on COS concerning other metabolic illnesses is still lacking. Among various production strategies, pretreatment and enzymatic hydrolysis are preferred for the production of COS. Functional oligosaccharides can add value to coffee waste and reduce the environmental impact of coffee manufacturing, besides providing more options for healthy and active ingredients. This review updates COS, production, bio-activity, their role as a functional food, food supplements/natural food additives, prebiotics and many applications of health sectors. Research is desirable to extend information on COS and their bio-activity, besides in vivo and clinical trials, to assess their effects in prior human formulations into the food and therapeutic arena.

Abstract
One of the emerging non-digestible oligosaccharide prebiotics is β-mannooligosaccharides (β-MOS). β-MOS are β-mannan derived oligosaccharides, they are selectively fermented by gut microbiota, promoting the growth of beneficial microorganisms (probiotics), whereas the growth of enteric pathogens remains unaffected or gets inhibited in their presence, along with production of metabolites such as short-chain fatty acids. β-MOS also exhibit several other bioactive properties and health-promoting effects. Production of β-MOS using the enzymes such as β-mannanases is the most effective and eco-friendly approach. For the application of β-MOS on a large scale, their production needs to be standardized using low-cost substrates, efficient enzymes and optimization of the production conditions. Moreover, for their application, detailed in-vivo and clinical studies are required. For this, a thorough information of various studies in this regard is needed. The current review provides a comprehensive account of the enzymatic production of β-MOS along with an evaluation of their prebiotic and other bioactive properties. Their characterization, structural-functional relationship and in-vivo studies have also been summarized. Research gaps and future prospects have also been discussed, which will help in conducting further research for the commercialization of β-MOS as prebiotics, functional food ingredients and therapeutic agents.

Enzyme Microb Technol 2023; 165:110197. [PMID: 36680817 DOI: 10.1016/j.enzmictec.2023.110197] [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: 09/13/2022] [Revised: 01/10/2023] [Accepted: 01/15/2023] [Indexed: 01/19/2023]
Abstract
A novel glycoside hydrolase family 26 β-mannanase gene ppman26a was cloned from Paenibacillus polymyxa KF-1. The full-length enzyme PpMan26A and its truncated products CBM35pp (aa 35-328) and PpMan26A-Δ205 (aa 206-656) were overexpressed in Escherichia coli. PpMan26A hydrolyzed locust bean gum, guar gum, konjac gum and ivory nut mannan, with the highest specific activity toward konjac gum. The Km and kcat values for konjac gum were 2.13 mg/mL and 416.66 s-1, respectively. The oligosaccharides fraction obtained from the hydrolysis of konjac gum by PpMan26A was analyzed by matrix-assisted laser desorption ionization-time-of-flight mass spectrometer (MALDI-TOF-MS). The degradation products were mainly mannooligosaccharides with a degree of polymerization of 3-8. CBM35pp exerted strong binding activity toward mannans but without β-mannanase activity. PpMan26A-Δ205, with the deletion of the N-terminal CBM domain, showed lower substrate binding capacity, resulting in reduced enzymatic activity and thermostability. This study complements our understanding of GH26 β-mannanases and expands the potential industrial application of PpMan26A.

Heterologous Expression, Purification and Characterization of an Alkalic Thermophilic β-Mannanase CcMan5C from Coprinopsis cinerea. J Fungi (Basel) 2023; 9:jof9030378.

Abstract
A endo-1,4-β-mannanase (CcMan5C) gene was cloned from Coprinopsis cinerea and heterologously expressed in Pichia pastoris, and the recombinant enzyme was purified by Ni-affinity chromatography and identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/TOF-MS). CcMan5C hydrolyzed only locust bean gum galactomannan (LBG) but not α-mannan from S. cerevisiae or Avicel cellulose, oat spelt xylan, or laminarin from Laminaria digitata. CcMan5C exhibited distinctive catalytic features that were different from previously reported β-mannanases. (1) CcMan5C is the first reported fungal β-mannase with an optimal alkalic pH of 8.0-9.0 for hydrolytic activity under assay conditions. (2) CcMan5C is the first reported alkalic fungal β-mannase with an optimal temperature of 70 °C for hydrolytic activity under assay conditions. (3) The organic solvents methanol, ethanol, isopropanol, and acetone at concentrations of 10% or 20% did not inhibit CcMan5C activity, while 10% or 20% isopropanol and acetone even enhanced CcMan5C activity by 9.20-34.98%. Furthermore, CcMan5C tolerated detergents such as Tween 20 and Triton X-100, and its activity was even enhanced to 26.2-45.6% by 1% or 10% Tween 20 and Triton X-100. (4) CcMan5C solution or lyophilized CcMan5C exhibited unchanged activity and even increasing activity after being stored at -20 °C or -80 °C for 12 months and retained above 50% activity after being stored at 4 °C for 12 months. These features make CcMan5C a suitable candidate for the detergent industry and paper and pulp industry.

Abstract
Background A chronic inflammatory disease caused by disturbances in metabolism, diabetic nephropathy (DN) is a chronic inflammatory disease. Pyroptosis is a novel form of programmed cell death in many inflammation-related diseases, including DN. Therefore, pyroptosis could be a promising target for DN therapy. Methods To get the components and pharmacodynamic targets of Chuanxiong, we identified by searching TCMID, TCMSP, ETCM and HERB databases. Then, from the Molecular Signatures Database (MSigDB) and Gene Ontology (GO) database, pyroptosis genes were collected. Identification of critical genes in DN by bioinformatics analysis and then using the ConsensusClusterPlus package to divide the express data of diff genes into some subgroups with different levels of pyroptosis; the WGCNA machine algorithm was used to simulate the mechanism Chuanxiong improving DN. Results In this study, we found DHCR24, ANXA1, HMOX1, CDH13, ALDH1A1, LTF, CHI3L1, CACNB2, and MTHFD2 interacted with the diff genes of DN. We used GSE96804 as a validation set to evaluate the changes of APIP, CASP6, CHMP2B, CYCS, DPP8, and TP53 in four different cell proapoptotic states. WGCNA analysis showed that DHCR24, CHI3L1, and CACNB2 had significant changes in different cell proapoptotic levels. In the experimental stage, we also confirmed that the active ingredients of Chuanxiong could improve the inflammatory state and the levels of pyroptosis under high glucose. Conclusion The improvement of DN by Chuanxiong is related to the change of pyroptosis.
