PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2025; 141:156710.

Abstract
BACKGROUND Aging-related liver and brain damage caused by oxidative stress and inflammation significantly impacts health and quality of life. Natural bioactive compounds, such as 6'-O-caffeoylarbutin (CA), which is primarily distributed in Vaccinium species, have been studied for their antioxidant and anti-inflammatory properties. This study aims to investigate the protective effect on liver and brain damage induced by D-galactose (D-gal) in mice and to explore its potential molecular mechanisms. PURPOSE This study aims to investigate the protective effects of CA on D-galactose (D-gal)-induced liver and brain damage in mice and to explore its potential molecular mechanisms. METHODS CA was prepared from Vaccinium dunalianum and identified using UHPLC-ESI-HR-MS/MS. Molecular docking and network pharmacology analysis were performed to predict the binding of CA with SIRT1 and NF-κB1 targets. In vivo, a D-gal-induced aging mouse model was established to evaluate the biochemical, oxidative stress, and inflammatory parameters. The effects of CA on oxidative stress and inflammation were examined through enzymatic activity assays, cytokine level measurements, and histopathological analysis. Western blotting was used to validate the involvement of the SIRT1/NF-κB pathway. RESULTS CA treatment significantly alleviated liver and brain damage in D-gal-induced mice by decreasing AChE, AST, and ALT activities, improving organ indices, and reducing histopathological alterations. CA enhanced antioxidant defense by increasing SOD, CAT, and T-AOC activities, elevating GSH levels, and decreasing MDA content. Furthermore, CA suppressed the inflammatory response by downregulating IL-6 and TNF-α levels. Mechanistically, CA inhibited NF-κB p65 phosphorylation and suppressed iNOS and COX-2 expression, likely via activation of the SIRT1 protein. CONCLUSION This study demonstrates that CA protects against D-gal-induced oxidative stress and inflammation in liver and brain tissues via the SIRT1/NF-κB pathway, supporting its potential as a bioactive compound for preventing aging-related liver and brain damage.

Dunhuang Dabupi Decoction and its active components alleviate ulcerative colitis by activating glutathione metabolism and inhibiting JAK-STAT pathway in Drosophila and mice. JOURNAL OF ETHNOPHARMACOLOGY 2025; 346:119717. [PMID: 40164365 DOI: 10.1016/j.jep.2025.119717] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2025] [Revised: 03/22/2025] [Accepted: 03/28/2025] [Indexed: 04/02/2025]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Dabupi Decoction (DBPD) originates from the ancient Dunhuang medical literature "Fu Xing Jue Visceral to Drug law legend" for more than 1000 years, which has been extensively employed to treat various diseases related to the spleen and stomach. However, limited studies focus on the mechanism of DBPD against ulcerative colitis (UC). AIM OF THE STUDY The beneficial effect and mechanism of DBPD against UC were detected by adopting both Drosophila melanogaster and C57BL/6J mouse models. METHODS The protective effect of DBPD against DSS-induced intestinal damage in flies was investigated by utilizing survival rate, locomotion, excretion, smurf, intestinal length, intestinal acid-base homeostasis, and Tepan blue assay. In mice, HE staining and ELISA kit were employed to assess serum histopathological damage and inflammatory factor levels. Subsequently, the molecular mechanism of DBPD was subsequently detected via DHE staining, immunofluorescence, transmission electron microscopy (TEM), real-time PCR, and transcriptomic sequencing. Additionally, liquid chromatography-mass spectrometry (LC-MS) and phenotype experiments in UC flies were utilized to identify the bioactive components of DBPD against UC. RESULTS Oral administration of DBPD remarkably alleviated DSS-induced body damage in flies by improving survival rate, locomotion, and excretion. It also remarkably rescued intestinal morphological damage, repaired acid-base homeostatic imbalance, inhibited intestinal epithelial cells (IECs) death and excessive proliferation of intestinal stem cells (ISCs), and improved ultrastructural damage of IECs in flies treated with DSS. Consistently, DBPD attenuated colitis symptoms, alleviated intestinal histopathological damage, and restored the expression of inflammatory factors in DSS-induced UC mice. As suggested by an integration of transcriptome data with molecular biology experiments, DBPD not only dramatically alleviated oxidative damage by activating the glutathione metabolic pathway, but also lowered inflammatory reaction by inhibiting the JAK-STAT pathway. Additionally, four compounds of DBPD, rhein acid, isoquercitrin, curcumin, and zeaxanthin were identified to alleviate the DSS-induced intestinal injury. CONCLUSION DBPD demonstrate immense potential for intestinal injury predominantly by activating the glutathione metabolic pathway to alleviate oxidative damage, and inhibiting the JAK-STAT pathway to mitigate inflammatory response. Rhein acid, isoquercitrin, curcumin, and zeaxanthin were the bioactive compounds of DBPD against UC.

Abstract
Bletilla striata polysaccharide (BSP) is a natural bioactive compound known for its promising health benefits, including antioxidant, immunomodulatory, and anti-inflammatory effects. However, its potential in combating aging remains largely unexplored. This study aims to investigate the anti-aging effects of BSP in the Drosophila melanogaster model. The results show that BSP supplementation significantly extends the lifespan of flies in a concentration-dependent manner, with the most pronounced effects observed at a concentration of 3 mg/mL. Lifespan extension is associated with enhanced antioxidative capacities, as evidenced by increased SOD and CAT activities, and decreased MDA content. Additionally, BSP ameliorates age-related symptoms, including improved climbing ability and enhanced intestinal barrier function. Furthermore, BSP supplementation enhances resistance to H2O2-induced oxidative and starvation stresses, attenuates the lead (Pb)-induced toxicity, and delays the onset of Alzheimer's phenotypes in flies. RNA-Seq analysis reveals that BSP supplementation leads to the differential expression of 992 genes. KEGG pathway analysis highlights significant changes in metabolic pathways, including galactose metabolism, starch and sucrose metabolism, and carbon metabolism. Key genes such as Mal-A1, Amy-d, Men-b, Pgm-1, Mdh1, and Hex-C are downregulated, while CG32026, CG11291, and Ald2 are upregulated. These findings suggest BSP exhibits significant anti-aging and protective properties, making it a potential therapeutic agent.

Abstract
Poria cocos polysaccharides (PCP), the main component of Poria cocos, possess a variety of biological activities, including antitumor, immunomodulatory, and antioxidant effects. However, whether PCP has an antiaging effect remains unclear. Here, we studied the beneficial effects and the mechanism of PCP on delaying aging using the Drosophila model. The results showed that the dietary supplementation of PCP significantly extended the lifespan, improved the climbing ability, attenuated intestinal barrier dysfunction, alleviated gastrointestinal acid-base imbalance, and prevented intestinal stem cells (ISCs) hyperproliferation. In addition, PCP notably increased the activities of SOD and CAT and reduced the content of MDA. Furthermore, RNA-Seq showed that PCP supplementation led to the differential expression of 638 genes. KEGG analysis revealed that these differentially expressed genes were strongly enriched in the signaling pathway of cofactor biosynthesis. Among these genes, the expression of the branched-chain amino acid transferase-encoding gene (bcat) was significantly downregulated. The bcat-knockdown prolonged the flies' lifespan, while bcat-overexpression reduced the lifespan. Interestingly, PCP addition can rescue the flies' lifespan in the background of bcat-overexpression. Taken together, our data indicate that PCP delays aging by enhancing the antioxidant ability and suppressing the expression of the bcat gene in Drosophila.

Abstract
Background Ulcerative colitis (UC) is a chronic intestinal inflammation that is prone to relapse and is difficult to fully recover; therefore, there is a need for safer alternative treatments. Caffeic acid (CA) is a natural polyphenolic compound that has antioxidant and anti-inflammatory properties. However, the beneficial effects and mechanisms of action of CA in UC remain unclear. Purpose This study evaluated the protective effect of CA against dextran sulfate sodium (DSS)-induced intestinal injury in Drosophila melanogaster model. Results Oral administration of CA significantly reduced body damage in UC flies, improved their survival rate, restored damaged digestion, and improved locomotion. CA supplementation significantly alleviated intestinal damage in UC flies by restoring excretion balance, repairing intestinal atrophy, improving acid-base balance imbalance, inhibiting intestinal structural destruction, inhibiting intestinal epithelial cell death and intestinal stem cell (ISC) excessive proliferation, and reducing the number of harmful bacteria. Mechanistic studies found that CA significantly reduced the expression of Toll and Imd pathway genes (including Myd88, Dif, PGRP-LC, Imd, Rel, and Dpt), reduced ROS levels and the expression of apoptosis-related genes (Debcl, Cyt-c-p, DrlCE, Dronc, and Dark), and increased ATP and MFN2 levels. Conclusion CA alleviated intestinal damage mainly by inhibiting the Toll and Imd signaling pathways and inhibiting apoptosis mediated by mitochondrial damage. These findings suggest that CA holds promise as a potential therapeutic for UC treatment.

Abstract
Primulina plants native to karst regions are exceptionally rich in calcium and have been developed into high‑calcium leafy vegetables. However, limited knowledge of their metabolites, taste characteristics, and potential medicinal value restricts further genetic improvements. This study conducted a comprehensive analysis on three breeding species of Primulina vegetables. Common garden experiment demonstrated significant calcium enrichment capability, with calcium content ranging from 204.45 to 391.52 mg/100 g. Through widely-targeted metabolomics, 1121 metabolites were identified within these Primulina vegetables. Furthermore, comparative analysis identified 976 differentially accumulated metabolites across nine comparison groups, driven mainly by flavonoids, phenolic acids, and lipids. Integration of electronic tongue analysis and metabolomics revealed taste profiles and identified 17 key candidate compounds related to taste. Based on network pharmacology analysis, 32 active ingredients were found in Primulina vegetables, which highlighted potential medicinal value. These findings provide a data-driven foundation for breeding programs aimed at enhancing nutritional and flavor traits.

Nutrients 2024; 16:4298. [PMID: 39770921 PMCID: PMC11677849 DOI: 10.3390/nu16244298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2024] [Revised: 12/05/2024] [Accepted: 12/10/2024] [Indexed: 01/11/2025] Open
Abstract
Background: Intestinal aging is characterized by declining protein homeostasis via reduced proteasome activity, which are hallmarks of age-related diseases. Our previous study showed that caffeine intake improved intestinal integrity with age by reducing vitellogenin (VIT, yolk protein) in C. elegans. In this study, we investigated the regulatory mechanisms by which caffeine intake improves intestinal integrity and reduces vitellogenin (VIT) production in aged Caenorhabditis elegans. Methods: We performed RNA-seq analysis, and qRT-PCR to validate and confirm the RNA-seq results. Transgenic worms with VIT-2::GFP and VIT-6::GFP were used for measuring VIT production. dsRNAi was conducted to elucidate the roles of pas-1 and pas-3 genes. Results:pas-1 and pas-3, a C. elegans ortholog of human PASM4, was upregulated by caffeine intake. They reduced VIT production by repressing unc-62, a transcriptional activator of vit expression. Interestingly, vit-2 was required for pas-1 and pas-3 expression, and RNAi of pas-1 and pas-3 promoted intestinal atrophy and colonization, suggesting a balancing mechanism for VIT levels in intestinal health. Additionally, lifespan was extended by caffeine intake (2 ± 0.05 days), however, this effect was not observed by pas-1 but not pas-3 RNAi, suggesting that the mode of action for an anti-aging effect of caffeine through pas-1 and pas-3 is distinctive. The lifespan extended by pas-1 was mediated by SKN-1 activation. Conclusions: Caffeine intake enhances intestinal health through proteasome activity and extends lifespan in aged C. elegans by upregulating pas-1 and pas-3. These findings suggest that caffeine consumption mitigates age-related proteasome impairment and maintains intestinal integrity during aging.

Phytosterols in mountain cultivated ginseng, as master healthy ageing dietary supplement, activates steroid signaling in ageing Drosophila melanogaster. Exp Gerontol 2024; 195:112554.

Abstract
Mountain cultivated ginseng (MCG) is planted in mountain forests to simulate traditional wild ginseng; therefore, it has a greater pharmacological effect than cultivated ginseng (CG) in the garden; however, insufficient evidence confirms this theory. In light of the health-promoting and life-extending properties of ginseng, we analyzed the efficacy of MCG and CG. Initial observations revealed that the phytosterols content of MCG was higher than that of CG, with a positive correlation to the duration of growth. The distinction between phytosterols in MCG and in CG is predominately determined by the stigmasterol content using High-Performance Liquid Chromatography (HPLC). The lifespan of Drosophila melanogaster (fruit flies) that aged naturally was prolonged by phytosterols in MCG and CG and stigmasterols. Further, they prolonged healthy ageing as measured by progeny numbers, length of sleep, climbing distance, and survival following oxidative damage. The findings of behavioral observations revealed that phytosterols in MCG were more efficacious than in CG in promoting health maintenance and life extension; moreover, stigmasterol indicated that these effects were dose-dependent. Stigmasterols, phytosterols in MCG and CG have restored age-associated decreases in steroid hormone levels. Notably, molecular docking was predicted to promote stigmasterol's binding to the steroid hormone receptor ECR due to its similarity to steroid hormones. In addition, stigmasterols triggered the steroid hormone signaling pathway by increasing the activity of key genes Eip75B and Br in 20E signaling and Jhamt, HmGR, Met, and Kr-h1 in JH signaling. Phytosterols, as a natural product, regulated health and longevity as a dietary supplement similar to that of steroids, which supported the social requirements of healthy ageing.

Abstract
Coffee is not only a delicious beverage but also an important dietary source of natural antioxidants. We live in a world where it is impossible to avoid pollution, stress, food additives, radiation, and other sources of oxidants that eventually lead to severe health disorders. Fortunately, there are chemicals in our diet that counteract the hazards posed by the reactive species that trigger oxidative stress. They are usually referred to as antioxidants; some of them can be versatile compounds that exert such a role in many ways. This review summarizes, from a chemical point of view, the antioxidant effects of relevant molecules found in coffee. Their mechanisms of action, trends in activity, and the influence of media and pH in aqueous solutions, are analyzed. Structure-activity relationships are discussed, and the protective roles of these compounds are examined. A particular section is devoted to derivatives of some coffee components, and another one to their bioactivity. The data used in the analysis come from theoretical and computational protocols, which have been proven to be very useful in this context. Hopefully, the information provided here will pro-mote further investigations into the amazing chemistry contained in our morning coffee cup.

J Food Sci 2024; 89:5559-5575. [PMID: 39150685 DOI: 10.1111/1750-3841.17276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2024] [Revised: 07/07/2024] [Accepted: 07/11/2024] [Indexed: 08/17/2024]
Abstract
Ara h1 was the highest content of peanut allergen protein, identified as a biomarker of peanut allergen. In this study, Ara h1 was covalently complexed with caffeic acid (CA) to research the effects of covalent conjugation on the antigenicity and protein structural properties of Ara h1. After the covalent complexing of Ara h1 and CA, the IgG-binding capacity of Ara h1 was reduced compared with that of control Ara h1. Moreover, the structure of Ara h1 changed from ordered to disordered, the number of intermolecular hydrogen bonds decreased, and some hydrophobic groups were exposed or hydrophobic peptides were released. The carboxyl group in CA reacted with the amino group in Ara h1. The digestibility of Ara h1-CA was increased. The antigenicity of Ara h1-CA was undetectable after 30 min of digestion in vitro. These findings can serve as a reference for further research on hypoallergenic peanut products.

Curr Biol 2024; 34:2785-2800.e7. [PMID: 38823381 DOI: 10.1016/j.cub.2024.05.009] [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: 12/13/2023] [Revised: 04/11/2024] [Accepted: 05/07/2024] [Indexed: 06/03/2024]
Abstract
Host-microbe interactions influence intestinal stem cell (ISC) activity to modulate epithelial turnover and composition. Here, we investigated the functional impacts of viral infection on intestinal homeostasis and the mechanisms by which viral infection alters ISC activity. We report that Drosophila A virus (DAV) infection disrupts intestinal homeostasis in Drosophila by inducing sustained ISC proliferation, resulting in intestinal dysplasia, loss of gut barrier function, and reduced lifespan. We found that additional viruses common in laboratory-reared Drosophila also promote ISC proliferation. The mechanism of DAV-induced ISC proliferation involves progenitor-autonomous epidermal growth factor receptor (EGFR) signaling, c-Jun N-terminal kinase (JNK) activity in enterocytes, and requires Sting-dependent nuclear factor κB (NF-κB) (Relish) activity. We further demonstrate that activating Sting-Relish signaling is sufficient to induce ISC proliferation, promote intestinal dysplasia, and reduce lifespan in the absence of infection. Our results reveal that viral infection can significantly disrupt intestinal physiology, highlight a novel role for Sting-Relish signaling, and support a role for viral infection in aging.

Wang J, Li X, Wang X, Zhang C, Hao Y, Jin LH. The zinc finger protein CG12744 regulates intestinal stem cells in aged Drosophila through the EGFR and BMP pathways. Life Sci 2024; 340:122485. [PMID: 38311220 DOI: 10.1016/j.lfs.2024.122485] [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: 12/05/2023] [Revised: 01/23/2024] [Accepted: 01/31/2024] [Indexed: 02/08/2024]
Abstract
AIM Aging is a process characterized by a time-dependent decline in the functionality of adult stem cells and is closely associated with age-related diseases. However, understanding how aging promotes disease and its underlying causes is critical for combating aging. MAIN METHODS The offspring of UAS-Gal4 and CG12744RNAiDrosophila were cultured for 33 days to evaluate the role of CG12744 in the aging intestine. Immunofluorescence was performed to detect specific cell type markers for assessing proliferation and differentiation. qRT-PCR was used to observe the changes in signaling regulating intestinal homeostasis in the aging intestine after CG12744 knockdown. 16S rRNA-seq analysis was also conducted to elucidate the role of gut microbes in CG12744-mediated intestinal dysfunction. KEY FINDINGS The mRNA levels of CG12744 were significantly increased in the aged midguts. Knockdown of CG12744 in progenitor cells further exacerbates the age-related intestinal hyperplasia and dysfunction. In particular, upon depletion of CG12744 in progenitors, enteroblasts (EBs) exhibited an increased propensity to differentiate along the enteroendocrine cell (EE) lineage. In contrast, the overexpression of CG12744 in progenitor cells restrained age-related gut hyperplasia in Drosophila. Moreover, CG12744 prevented age-related intestinal stem cell (ISC) overproliferation and differentiation by modulating the EGFR, JNK, and BMP pathways. In addition, the inhibition of CG12744 resulted in a significant increase in the gut microbial composition in aging flies. SIGNIFICANCE This study established a role for the CG12744 in regulating the proliferation and differentiation of adult stem cells, thereby identifying a potential therapeutic target for diseases caused by age-related dysfunction stem cell dysfunction.

Abstract
Aging is an intricate process characterized by the gradual deterioration of the physiological integrity of a living organism. This unfortunate phenomenon inevitably leads to a decline in functionality and a heightened susceptibility to the ultimate fate of mortality. Therefore, it is of utmost importance to implement interventions that possess the capability to reverse or preempt age-related pathology. Caloric restriction mimetics (CRMs) refer to a class of molecules that have been observed to elicit advantageous outcomes on both health and longevity in various model organisms and human subjects. Notably, these compounds offer a promising alternative to the arduous task of adhering to a caloric restriction diet and mitigate the progression of the aging process and extend the duration of life in laboratory animals and human population. A plethora of molecular signals have been linked to the practice of caloric restriction, encompassing Insulin-like Growth Factor 1 (IGF1), Mammalian Target of Rapamycin (mTOR), the Adenosine Monophosphate-Activated Protein Kinase (AMPK) pathway, and Sirtuins, with particular emphasis on SIRT1. Therefore, this review will center its focus on several compounds that act as CRMs, highlighting their molecular targets, chemical structures, and mechanisms of action. Moreover, this review serves to underscore the significant relationship between post COVID-19 syndrome, antiaging, and importance of utilizing CRMs. This particular endeavor will serve as a comprehensive guide for medicinal chemists and other esteemed researchers, enabling them to meticulously conceive and cultivate novel molecular entities with the potential to function as efficacious antiaging pharmaceutical agents.

Abstract
BACKGROUND Intestinal stem cells (ISCs) are the reservoir source of various types of intestinal cells, and the decline of stem cell function in the gut may be a potential factor for aging-related disease. The present study aimed to explore the regulatory mechanisms of Panax ginseng C.A.Meyer (Araliaceae, Panax genus) that could restore gut aging by enhancing intestinal function and regulating ISCs in aging mice based on the Wnt/β-catenin signaling pathway. METHODS A total of 60 ICR male mice were randomly divided into control, model, metformin, and ginseng water decoction (GWD) 3.6, 1.8, and 0.9 g/kg groups. The aging model was induced by 1 % D-galactose (s.c. 0.1 mL/10 g) for 28 days. Moreover, GWD was given to aging mice intragastrically (i.g.) once a day for 28 successive days. The learning memory ability, pathological status, and function in the ileum tissue, the activity of digestive enzymes, and short-chain fatty acid (SCFA) content in the colon were evaluated, and the related mechanism was investigated. RESULTS Ginseng can decrease the escape latency time and increase the swimming speed and the number of crossing platforms in aging mice. Moreover, the pathology of ileum tissue improved, the length of the intestinal villi increased, and the width of the villi and the depth of the crypts decreased. The activities of trypsin, α-amylase, and lipase increased in duodenal content and intestinal mucosa. In the colon, the content of SCFA, such as acetic acid, propionic acid and butyric acid, increased, indicating that ginseng significantly improves intestinal function impairment. The mRNA expressions and protein levels of β-catenin, C-myc, GSK-3β, Lgr5, and Olfm4 were upregulated in the ginseng group. CONCLUSIONS Ginseng improves intestinal function and regulates the function of ISCs in order to protect intestinal health by activating the Wnt/β-catenin signaling pathway in aging mice.

Food Res Int 2023; 173:113482.

Abstract
Chlorogenic acid (CGA) and caffeic acid (CA) are two major phenolic acids in coffee. Though the International Agency for Research on Cancer has classified CA as a Group2B carcinogen, coffee consumption seems generally safe within the usual levels of intake and is more likely to benefit health than to harm it. We thus speculated that CGA may effectively suppress the carcinogenic potential of CA. In a molar ratio achievable in vivo, this study shows that CGA can inhibit (i) copper reduction caused by CA, (ii) CA oxidation caused by copper, (iii) the formation of hydroxyl radicals by CA and copper, and (iv) DNA damage induced by CA, quercetin or (-)-epigallocatechin-3-gallate in the presence of copper. CA tends to undergo autoxidation to produce hydrogen peroxide and quinone, which further reacts with proteins to form quinoproteins. This autoxidation at a tolerable level normally induces beneficial adaptive responses. This study shows that CGA is less efficient than CA in producing hydrogen peroxide and quinoprotein; however, together they synergistically produce hydrogen peroxide and quinoprotein in vitro at a molar ratio achievable in vivo. In conclusion, CGA can selectively regulate the prooxidant activities of CA depending on whether copper is involved or not. CGA could be viewed as an indispensable partner of CA in coffee, given its dual role in suppressing the carcinogenic potential of CA and boosting CA autoxidation which is beneficial for disease prevention.

Abstract
Fruits, vegetables, and spices are natural sources of bioactive phytochemicals, such as polyphenols, carotenoids, flavonoids, curcuminoids, terpenoids, and capsaicinoids, possessing multiple health benefits and relatively low toxicity. These compounds found in the diet play a central role in organism development and fitness. Given the complexity of the whole-body response to dietary changes, invertebrate model organisms can be valuable tools to examine the interplay between genes, signaling pathways, and metabolism. Drosophila melanogaster, an invertebrate model with its extensively studied genome, has more than 70% gene homology to humans and has been used as a model system in biological studies for a long time. The notable advantages of Drosophila as a model system, such as their low maintenance cost, high reproductive rate, short generation time and lifespan, and the high similarity of metabolic pathways between Drosophila and mammals, have encouraged the use of Drosophila in the context of screening and evaluating the impact of phytochemicals present in the diet. Here, we review the benefits of Drosophila as a model system for use in the study of phytochemical ingestion and describe the previously reported effects of phytochemical consumption in Drosophila.

Abstract
Hedysarum polybotrys polysaccharide (HPS) is one of the main active ingredients of Hedysarum with many health-beneficial properties, including antioxidant property, immunomodulatory, anti-inflammatory, and anti-tumor. However, the effect of HPS on anti-aging is still unclear. This study was to explore the protective function of HPS on aging and age-related diseases using Drosophila melanogaster. The results demonstrated that HPS supplementation promoted hatchability and prolonged lifespan by enhancing the antioxidative capacity. Administraction of HPS ameliorated age-related symptoms such as imbalanced intestinal homeostasis, sleep disturbances, and beta-amyloid (Aβ) induced Alzheimer's disease (AD) in flies, but did not modulate neurobehavioral deficits in the AD model of tauopathy and the Parkinson's disease (PD) model of Pink1 mutation. Overall, this study reveals that HPS has strong potential in the prevention of aging and age-related diseases, and provided a new candidate for the development of anti-aging drugs.

[PMID: 36801290 DOI: 10.1016/j.ijbiomac.2023.123632] [Citation(s) in RCA: 28] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 01/27/2023] [Accepted: 02/06/2023] [Indexed: 02/18/2023]
Abstract
Astragalus polysaccharide (APS) is a notable bioactive component of Astragalus membranaceus and has been extensively investigated for its pharmacological activities, including antioxidant, neuroprotection, and anticancer effects. However, the beneficial effects and mechanisms of APS on anti-aging diseases remain largely unknown. Here, we utilized the classic model organism Drosophila melanogaster to investigate the beneficial effects and mechanism of APS on aging-related intestinal homeostasis imbalance, sleeping disorders, and neurodegenerative diseases. The results showed that administration of APS significantly attenuated age-associated disruption of the intestinal barrier, loss of gastrointestinal acid-base balance, reduction in intestinal length, overproliferation of the intestinal stem cells (ISCs), and sleeping disorders upon aging. Furthermore, APS supplementation delayed the onset of Alzheimer's phenotypes in Aβ42-induced Alzheimer's disease (AD) flies, including the extension of lifespan and the increase in motility, but without rescuing neurobehavioral deficits in the AD model of taupathy and Parkinson's disease (PD) model of Pink1 mutation. In addition, transcriptomics was used to dissect updated mechanisms of APS on anti-aging, such as JAK-STAT signaling, Toll signaling, and IMD signaling pathways. Taken together, these studies indicate that APS plays a beneficial role in modulating aging-related diseases, thereby as a potential natural drug to delay aging.

Abstract
We fabricated a mussel-inspired hemocompatible polycarbonate membrane (PC) modified by the cross-linking of chondroitin sulfate and caffeic acid polymer using CA-CS via a Schiff base and Michael addition reaction and named it CA-CS-PC. The as-fabricated CA-CS-PC membrane shows excellent hydrophilicity with a water contact angle of 0° and a negative surface charge with a zeta potential of -32 mV. The antiadhesion property of the CA-CS-modified PC membrane was investigated by enzyme-linked immunosorbent assay (ELISA), using human plasma protein fibrinogen adsorption studies, and proved to have excellent antiadhesion properties, because of the lower fibrinogen adsorption. In addition, the CA-CS-PC membrane also shows enhanced hemocompatibility. Finally, blood cell attachment tests of the CA-CS-PC membrane were observed by CLSM and SEM, and the obtained results proved that CA-CS-PC effectively resisted cell adhesion, such as platelets and leucocytes. Therefore, this work disclosed a new way to design a simple and versatile modification of the membrane surface by caffeic acid and chondroitin sulfate and apply it for cell adhesion.

Abstract
Inflammatory bowel disease (IBD) is a chronic and life-treating inflammatory disease that can occur in multiple parts of the human intestine and has become a worldwide problem with a continually increasing incidence. Because of its mild early symptoms, most of them will not attract people's attention and may cause more serious consequences. There is an urgent need for new therapeutics to prevent disease progression. Natural products have a variety of active ingredients, diverse biological activities, and low toxicity or side effects, which are the new options for preventing and treating the intestinal inflammatory diseases. Because of multiple genetic models, less ethical concerns, conserved signaling pathways with mammals, and low maintenance costs, the fruit fly Drosophila melanogaster has become a suitable model for studying mechanism and treatment strategy of IBD. Here, we review the advantages of fly model as screening platform in drug discovery, describe the conserved molecular pathways as therapetic targets for IBD between mammals and flies, dissect the feasibility of Drosophila model in IBD research, and summarize the natural products for IBD treatment using flies. This review comprehensively elaborates that the benefit of flies as a perfact model to evaluate the therapeutic potential of phytochemicals against IBD.

Abstract
Inflammatory bowel disease (IBD) is a group of disorders characterized by chronic inflammation in the intestine. Several studies confirmed that oxidative stress induced by an enormous amount of reactive free radicals triggers the onset of IBD. Currently, there is an increasing trend in the global incidence of IBD and it is coupled with a lack of adequate long-term therapeutic options. At the same time, progress in research to understand the pathogenesis of IBD has been hampered due to the absence of adequate animal models. Currently, the toxic chemical Dextran Sulfate Sodium (DSS) induced gut inflammation in rodents is widely perceived as a good model of experimental colitis or IBD. Drosophila melanogaster, a genetic animal model, shares ~ 75% sequence similarity to genes causing different diseases in humans and also has conserved digestion and absorption features. Therefore, in the current study, we used Drosophila as a model system to induce and investigate DSS-induced colitis. Anatomical, biochemical, and molecular analyses were performed to measure the levels of inflammation and cellular disturbances in the gastrointestinal (GI) tract of Drosophila. Our study shows that DSS-induced inflammation lowers the levels of antioxidant molecules, affects the life span, reduces physiological activity and induces cellular damage in the GI tract mimicking pathophysiological features of IBD in Drosophila. Such a DSS-induced Drosophila colitis model can be further used for understanding the molecular pathology of IBD and screening novel drugs.

Abstract
Ageing, in a natural way, leads to the gradual worsening of the functional capacity of all systems and, eventually, to death. This process is strongly associated with higher metabolic and oxidative stress, low-grade inflammation, accumulation of DNA mutations and increased levels of related damage. Detrimental changes that accumulate in body cells and tissues with time raise the vulnerability to environmental challenges and enhance the risk of major chronic diseases and mortality. There are several theses concerning the mechanisms of ageing: genetic, free radical telomerase, mitochondrial decline, metabolic damage, cellular senescence, neuroendocrine theory, Hay-flick limit and membrane theories, cellular death as well as the accumulation of toxic and non-toxic garbage. Moreover, ageing is associated with structural changes within the myocardium, cardiac conduction system, the endocardium as well as the vasculature. With time, the cardiac structures lose elasticity, and fibrotic changes occur in the heart valves. Ageing is also associated with a higher risk of atherosclerosis. The results of studies suggest that some natural compounds may slow down this process and protect against age-related diseases. Animal studies imply that some of them may prolong the lifespan; however, this trend is not so obvious in humans.
