[PMID: 38460626 DOI: 10.1016/j.ijbiomac.2024.130720] [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: 12/15/2023] [Revised: 03/05/2024] [Accepted: 03/06/2024] [Indexed: 03/11/2024]
Abstract
Penthorum chinense Pursh is a traditional Miao medicine, mainly used in the treatment of liver diseases. In this study, an acidic heteropolysaccharide PCPP was isolated from P. chinense with an average molecular weight of 14.96 kDa. PCPP contained arabinogalactan and homogalacturonan segments, which is formed by 4-Galp-(1 → 5)-Araf-1 and 3,6-Galp-(1 → 6)-Galp-1,3 glycosidic linkage. A variety of side chains, including t-Glcp-(1 → 4)-Glcp-(1 → 4)-GlcpA-1, t-Xylp-(1→, and 2-Manp-(1 → 4)-GalpA-1,3 linked to the O-3 and O-6 of 3,6-Galp. The antioxidant activity measurement in three models demonstrated that PCPP exhibited ROS scavenging capacity, antioxidant ability in the cellular model, enhancement of oxidative stress resistance, and healthspan-promoting effect in the worm model. These results provided the theoretical fundament of PCPP as a potential natural antioxidant.

Immunomodulatory activity and protective effect of a capsular polysaccharide in Caenorhabditis elegans, isolated from Lactobacillus fermentum GBJ. Int J Biol Macromol 2023; 253:127443. [PMID: 37844812 DOI: 10.1016/j.ijbiomac.2023.127443] [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: 04/07/2023] [Revised: 08/31/2023] [Accepted: 10/12/2023] [Indexed: 10/18/2023]
Abstract
A capsular polysaccharide, namely CPS-2, was isolated from Lactobacillus fermentum GBJ, purified using DEAE-52 anion exchange chromatography, and structurally characterized. We found that CPS-2 is homogenous, has an average molecular weight of 377 KDa, and is mainly composed of galactose and glucose at a molar ratio of 1.54:1.00. Its backbone comprises α-D-Galp-(1 → 3), α-D-Galp-(1 → 3,6), β-D-Glcp-(1 → 2), β-D-Galp-(1 → 6), and α-D-Galp-(1 → 4) residues with a side chain of β-D-Glcp-(1→). CPS-2 exerts an immunomodulatory effect by improving the proliferation and phagocytosis of macrophage RAW264.7 and promoting the secretion of NO and cytokines. The maximum secretion levels of IL-1β, IL-6, IL-10, and TNF-α were 1.96-, 0.11-, 0.22-, and 0.46-fold higher than those of the control, respectively. Furthermore, CPS-2 could significantly enhance the antioxidant system, extend lifespan, and improve stress tolerance of Caenorhabditis elegans at both exposure doses of 31.25 and 62.5 μg/mL. The average lifespan of nematodes reached a maximum in the 62.5 μg/mL-treated group after 10.39 days, 6.56 h, and 23.56 h in normal, oxidative stress, and heat shock environment, with extension percentages of 16.61 %, 43.23 %, and 15.77 %, respectively; therefore, CPS-2 displays an anti-aging effect. The significant bioactivity of CPS-2 promotes its application as a promising immunomodulatory and anti-aging ingredient in the food or pharmaceutical field.

Abstract
Introduction: Polysaccharides are important components of Panax notoginseng that contribute to its immunomodulatory ability. This study aimed to isolate polysaccharides from notoginseng and investigate the structural feature and potential immunomodulatory activity. Methods: The polysaccharide was isolated from notoginseng by anion exchange and gel permeation chromatography. Its preliminary structure was characterized by Fourier transform infrared (FT-IR) spectroscopy, gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR) spectroscopy. The immunoregulatory function was further investigated in cyclophosphamide induced immunosuppressive mice, murine splenocytes and macrophages. Results: A novel homogeneous polysaccharide (PNPB1) was isolated from notoginseng with the molecular weight of 9.3 × 105 Da. Monosaccharide composition analysis indicated that PNPB1 consisted of Glc (88.2%), Gal (9.0%), Ara (2.4%) and trace GlcA, with the major backbone of (1→4)-linked α-Glcp, (1→6)-linked β-Glcp, and (1, 4→6)-linked β-Glcp. The polysaccharide was found to significantly enhance murine body weight, improve their thymus and spleen indices and increase the white blood cells (WBC). PNPB1 significantly enhanced splenic lymphocyte proliferation, NO and cytokine (TNF-α, IL-2, IL-10 and IFN-γ) production, as well as the phagocytosis and TLR2 expression of peritoneal macrophages, indicating potent immunoenhancement effect. Discussion: These findings provide a theoretical basis for elucidating the structure and immune activity of notoginseng polysaccharides.

Abstract
Zhuyeqing liquor (ZYQL) is well-known traditional functional liquor in China that contains twelve crude drugs. Studies have shown that ZYQL has many beneficial effects, but its anti-aging effect has not been reported. Here, we found that ZYQL had excellent antioxidant activity in vitro. In C. elegans, ZYQL could significantly extend the lifespan, and decreased aging related phenotype including accumulation of lipofuscin and the decrease of food intake and motility. Further, ZYQL significantly reduced ROS level and enhanced the antioxidant defense in C. elegans. ZYQL increased transcriptional activity of transcription factors HSF-1 and SKN-1, and ZYQL-mediated longevity was dependent on these factors. Taken together, the data suggested that ZYQL enhanced the transcriptional activity of transcription factors HSF-1 and SKN-1, which in turn increased oxidative/heat stress resistance to exert its anti-aging effect in C. elegans. Our results provide new insights into the beneficial effects and underlying mechanisms of ZYQL, which might be useful for further developing ZYQL into health or anti-aging beverages.

Abstract
Bioactive polysaccharides have numerous pharmacological effects that are beneficial to human health. Akebia trifoliata (Thunb.) Koidz. has great development prospects as a food resource with medicinal value. The polysaccharides (ATFP) were extracted from A. trifoliata fruit by an aqueous two-phase system. ATFP-3, purified with DEAE-52 and Sephadex G-200 from ATFP, was mainly composed of glucose (47.55%) and galactose (20.39%). Its hydroxyl radical scavenging rate was 89.30% at 1.60 mg/mL and its IC50 was 0.29 mg/mL. ATFP-3 significantly enhanced the survival rate of Caenorhabditis elegans under thermal or oxidative stress. Furthermore, ATFP-3 could prolong the lifespan of C. elegans and improve the activities of the antioxidant enzyme, while also decrease the accumulation of lipofuscin and the level of malondialdehyde (MDA) in aging worms. Thus, ATFP-3 has application potential in health benefits for humans.

Abstract
Polysaccharides were the key ingredients of many herbal medicines, and were responsible for multiple pharmacological activities. In this study, a novel polysaccharide fraction, named SLP-2, was isolated from Stauntonia leucantha fruits, and purified by DEAE-52 and Sephadex G-100 column chromatography. Furthermore, SLP-2 was identified by congo red, methylation, partial acid hydrolysis and NMR. The results indicated that the backbone of SLP-2 was composed of →4)-β-D-Galp-(1 → 4)-β-D-Galp-(1→ substituted at C-6 with 1,5-linked arabinan. SLP-2 had good anti-oxidation ability in vitro. Surprisingly, we found that reduction of carboxyl groups and methylation of hydroxyl groups enhanced the ability to scavenge 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radicals and inhibit lipid peroxidation, and weakened the activity to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and reduce ferric iron.

Abstract
Plant polysaccharides exhibit many biological activities that are remarkably affected by molecular size and structures. This study aimed to investigate the degradation effect of ultrasonic-assisted Fenton reaction on the Panax notoginseng polysaccharide (PP). PP and its three degradation products (PP3, PP5, and PP7) were obtained from optimized hot water extraction and different Fenton reaction treatments, respectively. The results showed that the molecular weight (Mw) of the degraded fractions significantly decreased after treatment with the Fenton reaction. But the backbone characteristics and conformational structure were similar between PP and PP-degraded products, which was estimated by comparing monosaccharides composition, functional group signals in FT-IR spectra, X-ray differential patterns, and proton signals in 1H NMR. In addition, PP7, with an Mw of 5.89 kDa, exhibited stronger antioxidant activities in both the chemiluminescence-based and HHL5 cell-based methods. The results indicated that ultrasonic-assisted Fenton degradation might be used to improve the biological activities of natural polysaccharides by adjusting the molecular size.

Abstract
Aging is a process of progressive deterioration of multiple physiological functions within an organism. This study investigated the anti-aging effects of polysaccharides extracted from ginsenoside residues (GRP) in Caenorhabditis elegans using physiological, microbiomic, and transcriptomic approaches. GRP treatment prolonged the mean lifespan of C. elegans by 58.60 % (19.64 days) and did not affect locomotive behaviors. It reduced levels of lipofuscin and reactive oxygen species (ROS), and increased superoxide dismutase activity, which prevented oxidative damage caused by aging. Microbiomic data indicated that GRP administration significantly altered the composition of gut flora and increased the abundance of beneficial bacteria. Transcriptomic analyses identified 201 differentially expressed genes (DEGs). GRP treatment may enhance fatty acid degradation and induce preferential synthesis of beneficial fatty acids. It may also activate the metabolism of certain amino acids. The transcriptomic data were reliably reproduced using seven vital DEGs, which were confirmed by qRT-PCR analysis. These findings show that GRP has positive effects that prolong lifespan and alleviate aging in C. elegans. GRP should be explored as an effective dietary supplement for the development of functional foods. We propose a potentially novel mechanism that more fully describes the anti-aging mechanisms induced by GRP.

Abstract
The antiaging effects of sea red rice bran in vivo, a new saline-tolerant sea rice byproduct containing high levels of ceramides (Cers), remain unknown. This study aimed to explore the antiaging effects exerted by Cers from sea red rice bran on Caenorhabditis elegans, assess its health indicators as well as tolerance, and then reveal the mechanism of action of Cers in prolonging the mean life span through genetic studies. The results indicated that the mean life span of Cers-treated C. elegans were dose-dependent in the range of 0.10-0.50 mg/mL. Additionally, Cers improved nematode motility, reduced lipofuscin accumulation, and enhanced resistance to heat stress and antioxidant enzyme activity. Genetic studies showed that Cers treatment had altered nematode gene expression. In addition, insulin/IGF-1 and jnk-1/mitogen-activated protein kinase (MAPK) signaling pathways successfully demonstrated the longevity effects of Cers intake. In short, these results suggest that Cers enhance the resistance of C. elegans and prolong its life span.

Structural features and antioxidant activities of polysaccharides from different parts of Codonopsis pilosula var. modesta (Nannf.) L. T. Shen. Front Pharmacol 2022; 13:937581. [PMID: 36091763 PMCID: PMC9449496 DOI: 10.3389/fphar.2022.937581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Accepted: 07/26/2022] [Indexed: 11/13/2022] Open
Abstract
In this study, three acidic polysaccharides from different plant parts of Codonopsis pilosula var. Modesta (Nannf.) L. T. Shen were obtained by ion exchange chromatography and gel filtration chromatography, and the yields of these three polysaccharides were different. According to the preliminary experimental results, the antioxidant activities of the polysaccharides from rhizomes and fibrous roots (CLFP-1) were poor, and was thus not studied further. Due to this the structural features of polysaccharides from roots (CLRP-1) and aerial parts (CLSP-1) were the object for this study and were structurally characterized, and their antioxidant activities were evaluated. As revealed by the results, the molecular weight of CLRP-1and CLSP-1 were 15.9 kDa and 26.4 kDa, respectively. The monosaccharide composition of CLRP-1 was Ara, Rha, Fuc, Xyl, Man, Gal, GlcA, GalA in a ratio of 3.8: 8.4: 1.0: 0.8: 2.4: 7.4: 7.5: 2.0: 66.7, and Ara, Rha, Gal, GalA in a ratio of 5.8: 8.9: 8.0: 77.0 in for CLSP-1. The results of structural elucidation indicated that both CLRP-1 and CLSP-1 were pectic polysaccharides, mainly composed of 1, 4-linked galacturonic acid with long homogalacturonan regions. Arabinogalactan type I and arabinogalactan type II were presented as side chains. The antioxidant assay in IPEC-J2 cells showed that both CLRP-1 and CLSP-1 promoted cell viability and antioxidant activity, which significantly increase the level of total antioxidant capacity and the activity of superoxide dismutase, catalase, and decrease the content of malondialdehyde. Moreover, CLRP-1 and CLSP-1 also showed powerful antioxidant abilities in Caenorhabditis elegans and might regulate the nuclear localization of DAF-16 transcription factor, induced antioxidant enzymes activities, and further reduced reactive oxygen species and malondialdehyde contents to increase the antioxidant ability of Caenorhabditis elegans. Thus, these finding suggest that CLRP-1 and CLSP-1 could be used as potential antioxidants.

Abstract
Two novel exopolysaccharides, named LPB8-0 and LPB8-1, were isolated and purified from Lactiplantibacillus pentosus B8. Moreover, their structure and bioactivities were evaluated through chemical and spectral means. The study results demonstrated that LPB8-0 was primarily composed of mannose and glucose and had an average molecular weight of 1.12 × 104 Da, while LPB8-1 was composed of mannose, glucose, and galactose and had an average molecular weight of 1.78 × 105 Da. Their carbohydrate contents were 96.2% ± 1.0% and 99.1% ± 0.5%, respectively. The backbone of LPB8-1 was composed of (1→2)-linked α-D-Manp and (1→6)-linked α-D-Manp. LPB8-0 and LPB8-1 had semicrystalline structures with good thermal stability (308.3 and 311.7 °C, respectively). SEM results displayed that both LPB8-0 and LPB8-1 had irregular thin-slice shapes and spherical body structures. Additionally, an emulsifying ability assay confirmed that LPB8-0 and LPB8-1 had good emulsifying activity against several edible oils, and this activity was retained under acidic, neutral, and high temperature conditions. Furthermore, an antioxidant assay confirmed that LPB8-1 had stronger scavenging activity than LPB8-0. Overall, these results provide a theoretical basis for the potential application of these two novel exopolysaccharides as natural antioxidants and emulsifiers in the food and pharmaceutical industries.

Abstract
22 edible oils can be discriminated based on tocopherol and phytosterol contents. In vitro antioxidant activity is correlated to polyphenol, tocopherol, and squalene. Oxidative and heat stress resistance is correlated to tocopherol and phytosterol. In vivo antioxidant activity is correlated to polyphenol, squalene, MUFA and PUFA.
In the last decade, with a growing emphasis on healthy diets, functional edible oils with high nutritional quality are becoming increasingly popular around the world. This study systematically compared the chemical composition and protective effect of 22 vegetable oils using multivariate chemometric tools. The results showed that the fatty acid composition and minor compounds were extremely variable among tested oils. Hierarchical cluster and principal component analysis discriminated these oils according to the tocopherol and phytosterol contents. The Pearson’s correlation analysis indicated that in vitro radical scavenging capacity was significantly correlated to polyphenol, tocopherol, and squalene. Additionally, the ameliorate effects on the heat and oxidative stress, ROS contents, and antioxidant enzyme activities were measured in Caenorhabditis elegans. The results showed that the antioxidant activity and stress resistance were positively correlated to polyphenol, tocopherol, phytosterol, MUFA, and PUFA, respectively. This study may offer an insight into oil discrimination and functional oil exploitation.

Abstract
Materials derived from natural plants and animals have great potential for transdermal drug delivery. Polysaccharides are widely derived from marine, herbal, and microbial sources. Compared with synthetic polymers, polysaccharides have the advantages of non-toxicity and biodegradability, ease of modification, biocompatibility, targeting, and antibacterial properties. Currently, polysaccharide-based transdermal drug delivery vehicles, such as hydrogel, film, microneedle (MN), and tissue scaffolds are being developed. The addition of polysaccharides allows these vehicles to exhibit better-swelling properties, mechanical strength, tensile strength, etc. Due to the stratum corneum’s resistance, the transdermal drug delivery system cannot deliver drugs as efficiently as desired. The charge and hydration of polysaccharides allow them to react with the skin and promote drug penetration. In addition, polysaccharide-based nanotechnology enhances drug utilization efficiency. Various diseases are currently treated by polysaccharide-based transdermal drug delivery devices and exhibit promising futures. The most current knowledge on these excellent materials will be thoroughly discussed by reviewing polysaccharide-based transdermal drug delivery strategies.

Abstract
Lentinan, extracted from Lentinus edodes, exhibits bioactive properties in vitro; however, little is known about the antioxidant potential in vivo. In this study, the effects of lentinan at 0.05, 0.25 and 1.25 mg/mL on the lifespan, locomotion, reproductive capacity, and oxidative stress resistance in Caenorhabditis elegans were determined. Compared to the untreated control, lentinan at 0.05, 0.25 and 1.25 mg/mL significantly prolonged the lifespan by 17.6%, 35.3% and 25.3% (p < 0.001), respectively, and improved the brood size, locomotion and stress resistance of the nematodes. Furthermore, lentinan at 0.25 mg/mL significantly reduced accumulation of intracellular reactive oxygen species (ROS) and malondialdehyde (MDA) by 38.1% (p = 0.013) and 49.7% (p = 0.028), respectively. In addition, lentinan at all tested concentrations significantly increased the activities of superoxide dismutase (SOD) and catalase (CAT). The expression of skn-1 and daf-16 in the treatments with lentinan at 0.25 and 1.25 mg/mL was significantly (p < 0.005) up-regulated compared with the untreated control, whereas that of the daf-2 gene was significantly down-regulated. Further evidence revealed that ROS production in lentinan-treated daf-16 and skn-1 mutant strains was similar to the untreated control. Consistent with the aforementioned results, lentinan enhanced the nuclear translocation of DAF-16 and SKN-1. Our results demonstrated that lentinan could increase lifespan and protect the nematodes from oxidative stress through DAF-16 and SKN-1.

Abstract
Schizophyllum commune (S. commune) fermented supernatant with added Radix Puerariae (SC-RP) showed significant antioxidant activity in our previous work. However, the possible lifespan and healthspan extending the capacity of Caenorhabditis elegans (C. elegans) and the underlying mechanism were not illuminated. In this study, the effect of SC-RP on extending the lifespan and improving stress resistance of C. elegans were examined. Additionally, the underlying lifespan extending molecular mechanisms of SC-RP were explored. Treated with SC-RP at 10 μg/mL, the lifespan of C. elegans increased by 24.89% (P < 0.01). Also, SC-RP prolonged the healthspan of the nematode, including reducing lipofuscin levels, improving mobility and enhancing resistance to oxidative stress and heat shock. Moreover, superoxide dismutase and catalase activities were increased for SC-RP treated C. elegans. Meantime the intracellular levels of thiobarbituric acid reactive substances (TBARS) and reactive oxygen species (ROS) were attenuated. Express levels of eight genes including daf-2, daf-16, sod-3, skn-1, gst-4, clk-1, age-1 and mev-1 were analyzed by RT-PCR method for possible C. elegan anti-aging mechanisms of SC-RP. Expression levels of key genes daf-2, gst-4 and sod-3 were up-regulated, while that of daf-16, skn-1, and clk-1 were down-regulated. The results suggest that SC-RP could extend the lifespan and healthspan of C. elegans significantly, and the IIS pathway, SKN-1/Nrf2 pathway and mitochondrial metabolism pathway were primarily considered associated. Thus, SC-RP is a potential component to improve aging and aging-related symptoms as new functional materials.

Abstract
Tangeretin is a polymethoxylated flavonoid naturally occurred in citrus fruits with many pharmacological activities, such as anti-inflammatory, antiproliferative, and neuroprotective properties. A previous study reported that tangeretin-enriched orange extract could prolong the lifespan in Caenorhabditis elegans. However, the antiaging effect of tangeretin remains uncertain. In this study, we used the model organism C. elegans to conduct a lifespan test, observed the aging-related functional changes of nematodes, the fluorescence changes of stress-related proteins (DAF-16 and HSP-16.2) and its response to stress assay, and monitored the effect of tangeretin on the mRNA expression levels. The results showed that tangeretin supplementation (30 and 100 μM) extended the mean lifespan, slowed aging-related functional declines, and increased the resistance against heat-shock stress. Furthermore, tangeretin upregulated the mRNA expression of daf-16, hsp-16.2, and hsp-16.49, promoted the nuclear localization of DAF-16, and enhanced the fluorescence intensity of HSP-16.2, while it had no effect on the lifespan of daf-2, age-1, and daf-16 mutants. The current findings suggest that tangeretin can significantly extend the lifespan and enhance heat stress tolerance in an insulin/insulin-like growth factor signaling dependent manner.

Abstract
The crisis of arsenic (As) accumulation in rhizomes threatens the quality and safety of Panax notoginseng (Burk.) F.H. Chen, which is a well-known traditional Chinese herb with a long clinical history. The uptake of arsenate (AsV) could be suppressed by supplying phosphate (Pi), in which Pi transporters play important roles in the uptake of Pi and AsV. Herein, the P . notoginseng Pi transporter-encoding gene PnPht1;3 was identified and characterised under Pi deficiency and AsV exposure. In this study, the open reading frame (ORF) of PnPht1;3 was cloned according to RNA-seq and encoded 545 amino acids. The relative expression levels revealed that PnPht1;3 was significantly upregulated under phosphate deficiency and AsV exposure. Heterologous expression in Saccharomyces cerevisiae MB192 demonstrated that PnPht1;3 performed optimally in complementing the yeast Pi-transport defect and accumulated more As in the cells. Combined with the subcellular localisation prediction, it was concluded that PnPht1;3 encodes a functional plasma membrane-localised transporter protein that mediates putative high-affinity Pi/H+ symport activity and enhances the uptake of Pi and AsV. Therefore, a better understanding of the roles of the P . notoginseng Pi transporter could provide new insight for solving As accumulation in medicinal plants.

Abstract
β-glucan is an important functional active component with relatively high content in barley. It is reported to possess various biological activities, including anti-oxidative stress, but its mechanism of action remains obscure. In the current study, C. elegans was used as an in vivo animal model to explore its anti-oxidative stress mechanism. We found that both RBG (raw barley β-glucan) and FBG (fermented barley β-glucan) could significantly reduce the ROS level in C. elegans under oxidative emergency conditions. In addition, both FBG and RBG had positive effects on SOD and CAT enzyme activity, and FBG treatment obviously reduced the MDA content in nematodes under oxidative stress. Moreover, FBG and RBG pretreatment could extend the median lifespan of C. elegans under oxidative stress. The CB1370 and CF1038 mutants further confirmed that daf-2 and daf-16 were necessary for FBG or RBG to participate in anti-oxidative stress, and the RT-PCR results also evidenced that β-glucans resist oxidative stress in C. elegans partially through the daf-2/daf-16 pathway. In summary, barley β-glucan has high potential to defense oxidative stress as a natural polysaccharide.

Abstract
Aging is a process global in nature. The age of living organisms contributes to the appearance of chronic diseases, which not only reduce the quality of life, but also significantly damage it. Modern medicines can successfully fight multiple diseases and prolong life. At the same time, medications have a large number of side effects. New research indicates that bioactive phytochemicals have great potential for treating even the most severe diseases and can become an alternative to medicines. Despite many studies in this area, the effects of many plant ingredients on living organisms are poorly understood. Analysis of the mechanisms through which herbal preparations influence the aging process helps to select the right active substances, determine the optimal doses to obtain the maximum positive effect. It is preferable to check the effectiveness of plant extracts and biologically active components with geroprotective properties in vivo. For these purposes, live model systems such as Rattus rattus, Mus musculus, Drosophila melanogaster, and Caenorhabditis elegans are used. These models help to comprehensively study the impact of the developed new drugs on the aging process. The model organism C. elegans is gaining increasing popularity in these studies because of its many advantages. This review article discusses the advantages of the nematode C. elegans as a model organism for studying the processes associated with aging. The influence of various BAS and plant extracts on the increase in the life span of the nematode, on the increase in its stress resistance and on other markers of aging is also considered. The review showed that the nematode C. elegans has a number of advantages over other organisms and is a promising model system for studying the geroprotective properties of BAS.

Abstract
Naringenin (NN) is one of the most abundant flavonoids in citrus and grapefruits and has been shown to have antioxidant properties in vitro. The purpose of the study is to examine the antioxidant and anti-aging activities of NN in C. elegans, and to further explore the molecular mechanism. The results showed that NN enhanced the lifespan under normal and oxidative stress induced by H2O2. After treatment with NN, locomotion capability was improved and aging pigment accumulation was suppressed. NN also delayed the paralysis and reversed the defective chemotaxis behavior induced by Aβ protein. Meanwhile, the treatment with NN enhanced the activities of antioxidant enzymes and reduced the accumulation of reactive oxygen species (ROS) and malondialdehyde (MDA) content. The possible targets and pathways interacting with NN were predicted by network pharmacology. Real-time PCR analysis indicated that NN upregulated the expression levels of daf-16, sek-1 and skn-1, downregulated the expression levels of daf-2, age-1 and akt-1, and further activated sod-3, ctl-1, ctl-2, gst-4 and mtl-1. Moreover, the selected mutant strains were used and molecular docking was conducted to further suggest that IIS and MAPK pathways could be involved in the NN-mediated longevity-promoting effect.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 279:114398. [PMID: 34242729 DOI: 10.1016/j.jep.2021.114398] [Citation(s) in RCA: 43] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2021] [Revised: 06/18/2021] [Accepted: 07/05/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Folium Artemisiae Argyi (FAA) is one kind of Chinese herbal medicine with a long history. It has widespread pharmacological activities such as antibacterial, anti-inflammatory, antioxidative, and hemostatic, among others. FAA is traditionally used for the treatment of eczema, respiratory diseases and gynecological diseases for hundreds of years. Flavonoids are reported as the main components of them. Recent studies focused on the antioxidant effect of its flavonoids in vitro, while few studies focused on the antioxidant effect in vivo, and the underlying mechanisms have not yet been elucidated. AIM OF THE STUDY The aim of this study was to evaluate the antioxidant activity of Folium Artemisia Argyi flavonoids (FAAF) and explore its possible molecular mechanism in Caenorhabditis elegans. The research and development of its medicinal value will beneficial to the resource utilization of FAA. MATERIALS AND METHODS Firstly, FAAF was prepared, purified and then qualitatively and quantitatively analyzed using LC-DAD-MS. Then, 1,1-diphenyl-2-trinitrophenylhydrazine (DPPH), 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), hydroxyl radical and ferric reducing antioxidant power (FRAP) assays were applied to investigate the antioxidant effect of FAAF in vitro. Meanwhile, a stress resistance assay was carried out to evaluate the antioxidant effect of FAAF in vivo. Moreover, superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reactive oxygen species (ROS) accumulation were determined to ascertain whether FAAF can increase the oxidant defense system of nematodes and reduce the accumulation of ROS. Lipofuscin and protein carbonylation assays were employed to test whether FAAF can increase the antioxidant capacity of nematodes to resist the growth health indicators related to antioxidation. At last, quantitative real-time polymerase chain reaction (qRT-PCR) was performed to evaluate the expression of genes related to antioxidation. The expression of green fluorescent protein (GFP) was further investigated using a fluorescence microscope in transgenic strains (SOD-3::GFP, GST-4::GFP, and HSP-16.2::GFP). RESULTS FAAF exhibited a strong antioxidant capacity and enhanced stress resistance in C. elegans. FAAF reduced ROS accumulation and improved the antioxidant defense system under acute stress. Moreover, FAAF prevented the accumulation of lipofuscin and protein carbonylation in C. elegans. FAAF also upregulated the gene expression levels of hsp-16.2, gst-4, sod-3, skn-1, daf-16, ctl-2, hsf-1 and increased SOD-3::GFP and GST-4::GFP expression. CONCLUSION These results demonstrated that FAAF exerted antioxidant activity in C. elegans. It was perhaps regulated by the insulin/insulin-like growth factor-1(IGF-1) signaling pathway.

Abstract
Oleuropein (OLE) is a secoiridoid glycoside that mainly exists in olives with multifaceted health benefits. The present study aimed to investigate the stress resistance and lifespan extension effects of OLE in Caenorhabditis elegans. The results showed that OLE could significantly prolong the lifespan of C. elegans by 22.29%. Treatment with OLE also significantly increased the survival rates of worms against lethal heat shock and oxidative stress. Meanwhile, OLE supplementation increased the expression and activity of antioxidant enzymes and suppressed the generation of malondialdehyde in nematodes. In addition, the results from mutants implied that OLE might mediate longevity and stress resistance via DAF-16/FoxO, which played a vital role in the insulin/IGF-1 signaling (IIS) pathway. To further identify the molecular targets of OLE, mRNA level and loss-of-function mutants of IIS-associated genes were investigated. The data revealed that OLE activated IIS by down-regulating the upstream components, daf-2 and age-1. Furthermore, another stress response and longevity pathway in parallel to DAF-16, SKN-1/Nrf2, was also shown to involve in OLE-induced beneficial effects. Collectively, these results provide the theoretical basis that OLE could enhance the stress resistance and increase the lifespan of C. elegans through the IIS and SKN-1/Nrf2 signaling pathways.

Abstract
BACKGROUND Momordica saponin extract (MSE) was found to not only improve longevity and neuroprotection but also alleviate fat accumulation in Caenorhabditis elegans in our previous study. However, the lipid-lowering activity of MSE alone could not fully explain its ability to improve health, so the antistress effects of MSE were further studied. METHODS Using C. elegans as an in vivo animal, the lifespan of MSE-treated C. elegans under various stressors (H2O2, paraquat and heat) and normal conditions was studied. Furthermore, the antioxidant activities of MSE were discussed. To study the underlying mechanisms, the expression of stress resistance genes and the resistance of related mutants to H2O2 stress were tested. RESULTS MSE significantly improved the lifespan of C. elegans under stress and normal conditions. Meanwhile, the mobility of C. elegans was also improved. Moreover, the activities of SOD and CAT and the ratio of GSH/GSSG were elevated. Consistently, the levels of ROS and lipid oxidation (the NEFA and MDA content) were reduced. Furthermore, MSE treatment upregulated the expression of the sod-3, sod-5, clt-1, clt-2, hsp-16.1 and hsp-16.2 genes. All biomarkers indicated that the antistress and anti-aging activities of MSE were due to its strong antioxidant activities. Finally, MSE induced nuclear DAF-16::GFP localization. Studies with mutants revealed that skn-1 and hsf-1 were involved in the activity of MSE, which might upregulate the expression of downstream stress-responsive genes. CONCLUSIONS Therefore, in addition to its lipid-lowering property, the ability of MSE to improve healthspan was also attributed to the stress resistance effect. Together, MSE might serve as a lead nutraceutical in geriatric research.

Abstract
Terpenes and their derivatives have been used conventionally as potential dietary supplements to boost the nutritional value of endless food products. Several plant-based complex terpenoid and their derivatives have been reported for a wide range of medicinal and nutritional properties. However, their simple counterparts, whose production is relatively easy, sustainable, and economic from food-grade microbial sources, have not been studied yet for any such biological activities. The present study aimed to investigate the longevity-promoting property and neuromodulatory effects of 3,3-dimethylallyl alcohol (Prenol), one of the simplest forms of terpenoid and a constituent of fruit aroma, in the animal model Caenorhabditis elegans. Prenol supplementation (0.25 mM) augmented the lifespan of wild-type nematodes by 22.8% over the non-treated worms. Moreover, a suspended amyloid-β induced paralysis and reduced α-synuclein aggregation were observed in Prenol-treated worms. The lifespan extending properties of Prenol were correlated with ameliorated physiological parameters and increased stress (heat and oxidative) tolerance in C. elegans. In silico and gene-specific mutant studies showed that pro-longevity transcription factors DAF-16, HSF-1, and SKN-1 were involved in the improved lifespan and health-span of Prenol-treated worms. Transgenic green fluorescent protein-reporter gene expression analysis and relative mRNA quantification (using real-time PCR) demonstrated an increase in the expression of DAF-16, HSF-1, and SKN-1 transcription factors and their downstream target genes in Prenol-treated worms. Together, the findings suggest that small molecules, like Prenol, could be explored as a potential alternate to develop therapeutics against aging and age-related ailments.

Abstract
The anti-aging activities on Caenorhabditis elegans of a polysaccharide, O-acetyl glucomannan (LPR), purified from roots of Lilium davidii var. unicolor Cotton, were assessed by observing the mean lifespan, reproduction, pharyngeal pumping and stress response on nematodes. Additionally, the fluorescence intensity of lipofuscin and the level of reactive oxygen species (ROS) were detected. Also the activities of superoxide dismutase (SOD), catalase (CAT) and contents of malondialdehyde (MDA) were determined by the kit method. The results showed that LPR effectively delayed the aging of C. elegans in a dose-dependent manner. When the concentration reached 4 mg/mL, LPR extended the mean lifespan of C. elegans by up to 40%, 61% (P < 0.01) and 50% (P < 0.05) under normal, thermal and oxidative stress culture conditions, respectively. Moreover, LPR remarkably increased the reproduction duration of the nematodes at a concentration of 1 mg/L, and significantly decreased the ROS and lipofuscin level of C. elegans in three dosage groups. Further study illustrated that LPR at 4 mg/mL strongly increased the activity of SOD and CAT by 39.03% (P < 0.01) and 41.89% (P < 0.05), and decreased the lipid peroxidation of MDA level in C. elegans by 52.59% (P < 0.005) compared to a control. It was inferred that LPR provided stress resistance to heat and oxidation, and prolonged the lifespan of wild type N2 C. elegans mainly by elevating the function of nematode antioxidant defense systems and by scavenging free radicals. These findings provided evidence for the anti-aging properties of this polysaccharide from L. davidii.

Abstract
Orange, with various bioactive phytochemicals, exerts various beneficial health effects, including anti-cancer, antioxidant, and anti-inflammatory properties. However, its anti-aging effects remain unclear. In this study, the Caenorhabditis elegans (C. elegans) model was used to evaluate the effects of orange extracts on lifespan and stress resistance. The results indicated that orange extracts dose-dependently increased the mean lifespan of C. elegans by 10.5%, 18.0%, and 26.2% at the concentrations of 100, 200, and 400 mg/mL, respectively. Meanwhile, orange extracts promoted the healthspan by improving motility, and decreasing the accumulation of age pigment and intracellular reactive oxygen species (ROS) levels without damaging fertility. The survival rates of orange extract-fed worms were obviously higher than those of untreated worms against thermal and ultraviolet-B (UV-B) stress. Moreover, the activities of superoxide dismutase (SOD) and catalase (CAT) were significantly enhanced while malondialdehyde (MDA) contents were diminished. Further investigation revealed that worms supplemented with orange extracts resulted in upregulated levels of genes, including daf-16, sod-3, gst-4, sek-1, and skn-1, and the downregulation of age-1 expression. These findings revealed that orange extracts have potential anti-aging effects through extending the lifespan, enhancing stress resistance, and promoting the healthspan.

Physicochemical characteristics and in vitro and in vivo antioxidant activity of a cell-bound exopolysaccharide produced by Lactobacillus fermentum S1. Int J Biol Macromol 2019; 139:252-261. [PMID: 31374277 DOI: 10.1016/j.ijbiomac.2019.07.200] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2019] [Revised: 07/22/2019] [Accepted: 07/29/2019] [Indexed: 11/27/2022]
Abstract
A cell-bound exopolysaccharide (c-EPS) from Lactobacillus fermentum S1 was isolated and purified to near homogeneity by anion exchange and gel filtration chromatography. The c-EPS is a homogeneous heteropolysaccharide with an average molecular weight of 7.19 × 105 Da and comprises mainly mannose, rhamnose, glucose, and galactose. Fourier transform infrared spectroscopy spectrum of the c-EPS exhibited typical characteristic absorption peaks of polysaccharides. Methylation and NMR analyses showed that the c-EPS had a backbone of α-D-Galp-(1 → 3), α-L-Rhap-(1 → 2), α-D-Glcp-(1 → 3), β-D-Galp-(1 → 3), β-D-Glclp-(1 → 2), and β-L-Rhap-(1 → 3,4) residues, terminated with α-D-Manp-(1 → residue. The advanced structure study indicated the c-EPS not to have a triple-helical conformation, while the microstructural study revealed a hollow porous structure for c-EPS. Further, the thermal analysis showed that the degradation temperature for the c-EPS was 288.0 °C; its peak temperature was 89.4 °C with an enthalpy value of 273.1 J/g. Moreover, the c-EPS exhibited potent DPPH, hydroxyl, and ABTS+ radicals scavenging activities, as well as FRAP in a dose-dependent manner, which could significantly enhance the T-AOC and SOD activity and reduce MDA level in Caenorhabditis elegans. Therefore, this c-EPS could be utilized as a promising natural antioxidant for application in functional foods.

Abstract
In the present study, six different polysaccharides (RFPs, MAPs, UWPs, AEPs, HWPs and CEPs) were extracted from Chlorella vulgaris using repeated freeze-thawing, microwave-assisted-, ultrasonic wave-, alkali-, hot water-, and cellulase-based methods; and antioxidant property assays were performed both in vitro and in vivo. Radical-scavenging capacity (using DPPH, superoxide and hydroxyl radicals) and metal chelating ability were assessed in vitro; Caenorhabditis elegans was used to assess antioxidant effects in vivo. Based on the in vitro screening tests, UWPs exhibited high antioxidant capacity. The UWP yield was 17.1% ± 2.2%; the DPPH-, superoxide-, and hydroxyl radical-scavenging rates were 65.1% ± 2.4%, 61.2% ± 2.7%, and 56.2% ± 2.2%, respectively, and the metal chelating ability was 63.6% ± 2.5% at a concentration of 0.4 mg/mL. UWPs also exhibited high antioxidant activity in vivo. UWPs significantly increased the lifespan of C. elegans under oxidative stress induced by hydrogen peroxide compared with the control group, enhanced stress-resistance-related enzymes, including catalase and superoxide dismutase by 7.29% ± 1.8% and 24.41% ± 4.8%, respectively. The results of the present study indicate that the extraction methods of C. vulgaris polysaccharides were a key factor influencing antioxidant activity.

Abstract
The aim of this study was to evaluate the antioxidant activities of extracts from olive leaves (EOL). The main contents of EOL were determined by colorimetric methods. The antioxidant activities were assessed by measuring the scavenging free radicals in vitro. To investigate the antioxidant activity in vivo, we detected the survival of Caenorhabditis elegans, under thermal stress. Subsequently the reactive oxygen species (ROS) level, activities of antioxidant enzymes, the expression of HSP-16.2 and the translocation of daf-16 were measured. The results showed that, polyphenols was the main component. EOL could well scavenge DPPH and superoxide anion radicals in vitro. Compared to the control group, the survival rate of C. elegans treated with EOL was extended by 10.43%, under heat stress. The ROS level was reduced, while the expression of hsp-16.2 was increased to protect the organism against the increasing ROS. The level of malondialdehyde (MDA) also decreased sharply. The activities of inner antioxidant enzymes, such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-PX) were potentiated, which might have had a correlation with the DAF-16 transcription factor that was induced-turned into the nuclear. Therefore, EOL showed a strong antioxidant ability in vitro and in vivo. Hence, it could be a potential candidate when it came to medicinal and edible plants.
