Termite Fungus Comb Polysaccharides Alleviate Hyperglycemia and Hyperlipidemia in Type 2 Diabetic Mice by Regulating Hepatic Glucose/Lipid Metabolism and the Gut Microbiota. Int J Mol Sci 2024; 25:7430. [PMID: 39000541 PMCID: PMC11242180 DOI: 10.3390/ijms25137430] [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: 06/09/2024] [Revised: 06/29/2024] [Accepted: 07/01/2024] [Indexed: 07/16/2024] Open
Abstract
Type 2 diabetes (T2D) is a chronic metabolic disorder characterized by hyperglycemia and dyslipidemia. The termite fungus comb is an integral component of nests of termites, which are a global pest. Termite fungus comb polysaccharides (TFCPs) have been identified to possess antioxidant, anti-aging, and immune-enhancing properties. However, their physicochemical characteristics and their role in fighting diabetes have not been previously reported. In the current study, TFCPs were isolated and structurally characterized. The yield of TFCPs was determined to be 2.76%, and it was found to be composed of a diverse array of polysaccharides with varying molecular weights. The hypoglycemic and hypolipidemic effects of TFCPs, as well as their potential mechanisms of action, were investigated in a T2D mouse model. The results demonstrated that oral administration of TFCPs could alleviate fasting blood glucose levels, insulin resistance, hyperlipidemia, and the dysfunction of pancreatic islets in T2D mice. In terms of mechanisms, the TFCPs enhanced hepatic glycogenesis and glycolysis while inhibiting gluconeogenesis. Additionally, the TFCPs suppressed hepatic de novo lipogenesis and promoted fatty acid oxidation. Furthermore, the TFCPs altered the composition of the gut microbiota in the T2D mice, increasing the abundance of beneficial bacteria such as Allobaculum and Faecalibaculum, while reducing the levels of pathogens like Mailhella and Acetatifactor. Overall, these findings suggest that TFCPs may exert anti-diabetic effects by regulating hepatic glucose and lipid metabolism and the composition of the gut microbiota. These findings suggest that TFCPs can be used as a promising functional ingredient for the prevention and treatment of T2D.

Abstract
In regions reliant on fisheries for livelihoods, a significant number of fish by-products are generated annually due to processing. These discarded parts contain valuable biological resources, such as proteins, fish oils, and trace elements, thus holding enormous potential for reutilization. In recent years, fish by-product proteins have been widely utilized in skincare products due to their rich collagen content, biosafety, and biocompatibility. This review summarizes the research into and applications of fish by-product proteins in skin health, including alleviating oxidative stress and skin inflammation, reducing DNA damage, mitigating melanin production, improving skin hydration, slowing skin matrix degradation, and promoting synthesis. Additionally, the possibility of improving skin health by improving the abundance of gut microbiota is also discussed. This review underscores the importance of fish by-product proteins in the fisheries, food processing, cosmetics, and biomedical industries.

Effects of hydrolyzed collagen alone or in combination with fish oil on the gut microbiome in patients with major burns. Burns 2024; 50:444-453. [PMID: 38114377 DOI: 10.1016/j.burns.2023.08.017] [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: 12/09/2022] [Revised: 05/08/2023] [Accepted: 08/20/2023] [Indexed: 12/21/2023]
Abstract
Burns are associated with gut dysbiosis. Collagen peptides and omega-3 fatty acids (FAs) are suggested to improve wound healing and the inflammatory response. These are also correlated with microbiome colonization. Therefore, the present study aimed to investigate the effect of hydrolyzed collagen alone or in combination with fish oil on specific species of the gut microbiome in patients with major burns. In this randomized double-blind clinical trial, 57 adults (aged 18-60 years) with 20-45% total body surface area burns were randomised into three groups to receive either 40 gr hydrolyzed collagen +10 ml sunflower oil, 40 g hydrolyzed collagen +10 ml fish oil or placebo, divided into two daily drinks, for two weeks. Gut bacteria were measured using the real-time quantitative polymerase chain reaction (qPCR) method. The mean concentration of Bifidobacterium was significantly reduced in the control (P = 0.002) and collagen (P = 0.005) groups compared with the baseline values, whereas no significant change was observed in the collagen omega-3 group. The Firmicutes to Bacteroidetes ratio decreased significantly in the collagen group (p = 0.002) after supplementation compared to baseline . No significant changes in concentration of Lactobacillus, Enterobacteriaceae, and F.prausnitzii were observed between or within the study groups. Two weeks of supplementation with collagen and omega-3 FAs in patients with major burns did not result in a significant difference in the concentration of bacteria measured between the study groups. However, the addition of omega-3 FAs prevented a significant reduction in gut Bifidobacterium. Future studies are suggested to investigate the potential efficacy of these nutrients in improving the gut microbiota and clinical outcomes in major burns. REGISTRATION NUMBER: IRCT20131125015536N9.

Abstract
Refreshing beverages, consumed worldwide, commonly take advantage of caffeine's impacts on attention and motor performance. However, excessive long-term caffeine intake might disturb sleep/wake rhythms and exacerbate daily anxiety. Fish-originated collagen peptides (FCP) are of high nutrient value with stimulating, calming or relaxing effects, which could reduce the excitotoxicity of caffeine. This study aims to investigate two facets: (1) the combined effect of caffeine and FCP (namely C&F) on the cognitive function of sleep-deprived mice by different administration strategies with dose dependence (low and high dose) or time dependence (intervention in a day and prevention for a week); (2) the potential "microbiota-gut-brain" mechanism by which C&F improves sleep deprivation (SD)-induced cognitive impairments. Here, C57BL/6 mice were administered caffeine (10 or 20 mg per kg per bw) combined with FCP (100 or 200 mg per kg per bw) and were then subjected to 48 h SD. The open-field and Morris water maze tests were performed to evaluate the cognitive function and spatial learning capacities of mice. Our results indicated that the cognitive impairments of SD mice were significantly relieved to a different degree by treating C&F in a dose- and time-dependent manner. The pathological observation of the hippocampus indicated both intervention (time of a day) and prevention (time of a week) of the C&F protected brain tissue from SD-induced injuries. The accumulated pro-inflammatory neurometabolites and factors were significantly inhibited by C&F via the hypothalamus-hippocampal circuit. Furthermore, 16S rDNA analysis of colonic contents showed that the level of Lactobacillus murinus was significantly upregulated and that of Clostridia_UCG-014 was suppressed in the C&F group. The receiver operating characteristic (ROC) curve of Lactobacillus murinus indicated a certain diagnostic utility to distinguish C&F intervention (AUC = 0.52) or prevention (AUC = 0.68). Pathways of ko04622 (immune system) and ko00472 (metabolism processes) were significantly regulated by C&F in a time-dependent manner. Based on PICRUSt2 algorithm analysis, C&F might potentially regulate gut microbial functions through several metabolic pathways, including the RIG-I-like receptor signaling pathway and limonene and pinene degradation. In conclusion, C&F plays a key role in brain function and behavior, which could synergistically relieve cognitive impairments via the microbiota-gut-brain axis.

Abstract
Introduction Periodontal disease (PD) presents a substantial global health challenge, encompassing conditions from reversible gingivitis to irreversible periodontitis, often culminating in tooth loss. The gut-oral axis has recently emerged as a focal point, with potential gut microbiota dysbiosis exacerbating PD. Methods In this study, we employed a double-sample bidirectional Mendelian randomized (MR) approach to investigate the causal relationship between specific gut microbiota and periodontal disease (PD) and bleeding gum (BG) development, while exploring the interplay between periodontal health and the gut microenvironment. We performed genome-wide association studies (GWAS) with two cohorts, totalling 346,731 (PD and control) and 461,113 (BG and control) participants, along with data from 14,306 participants' intestinal flora GWAS, encompassing 148 traits (31 families and 117 genera). Three MR methods were used to assess causality, with the in-verse-variance-weighted (IVW) measure as the primary outcome. Cochrane's Q test, MR-Egger, and MR-PRESSO global tests were used to detect heterogeneity and pleiotropy. The leave-one-out method was used to test the stability of the MR results. An F-statistic greater than 10 was accepted for instrument exposure association. Results and conclusion Specifically, Eubacterium xylanophilum and Lachnoclostridium were associated with reduced gum bleeding risk, whereas Anaerotruncus, Eisenbergiella, and Phascolarctobacterium were linked to reduced PD risk. Conversely, Fusicatenibacter was associated with an elevated risk of PD. No significant heterogeneity or pleiotropy was detected. In conclusion, our MR analysis pinpointed specific gut flora with causal connections to PD, offering potential avenues for oral health interventions.

Abstract
The potential biological function of tea and its active components on colitis has attracted wide attention. In this study, different tea active ingredients including tea polyphenols (TPPs), tea polysaccharides (TPSs), theabrownin (TB), and theanine (TA) have been compared in the intervention of dextran sulfate sodium (DSS)-induced colitis in mice. Specifically, TPP showed the greatest effect on colitis since it reduced 60.87% of disease activity index (DAI) compared to that of the DSS-induced colitis group, followed by the reduction of 39.13% of TPS and 28.26% of TB on DAI, whereas there was no obvious alleviative effect of TA on colitis. TPP, TPS, and TB could regulate the composition and abundance of gut microbiota to increase the content of short-chain fatty acids (SCFAs) and enhance intestinal barrier function. Further evidence was observed that TPP and TPS regulated the activation of Nrf2/ARE and the TLR4/MyD88/NF-κB P65 pathway to alleviate the colitis. Results of cell experiments demonstrated that TPP showed the greatest antiapoptosis and mitochondrial function protective capability among the tea ingredients via inhibiting the Cytc/Cleaved-caspase-3 signaling pathway. In summary, the superior anticolitis activity of TPP compared to TPS and TB is primarily attributed to its unique upregulation of the abundance of Akkermansia and its ability to regulate the mitochondrial function.

Abstract
The aim of this study was to evaluate the intervention effect of the potential probiotic Kluyveromyces marxianus YG-4 isolated from Tibetan kefir grains on alcoholic liver disease (ALD). Eight-week-old male C57BL/6J mice were fed with a Lieber-DeCarli (LDC) diet containing ethanol with a progressively increasing concentration from 1% to 4% (vol/vol) to establish an ALD mouse model. Our results suggested that K. marxianus treatment improved ALD, as demonstrated by the reduction of serum ALT and AST levels and the suppression of TLR4/NF-κB-mediated inflammatory response in the liver. K. marxianus administration significantly elevated antioxidant activities of SOD, CAT and GSH-Px, and reduced the MDA level in mice. K. marxianus supplementation repaired the gut barrier by increasing tight junction proteins and the number of goblet cells in the colon of ALD mice. In addition, treatment with K. marxianus restored alcohol-induced gut dysbiosis. Specifically, K. marxianus administration depleted the abundance of Lactobacillus, Coriobacteriaceae_UCG-002 and Candida, while increased that of Allobaculum, Dubosiella and Epicoccum in mice. Our findings open new possibilities for K. marxianus application in ALD treatment.

Abstract
Collagen, the most abundant protein in our bodies, plays a crucial role in maintaining the structural integrity of various tissues and organs. Beyond its involvement in skin elasticity and joint health, emerging research suggests that collagen may significantly impact the treatment of complex diseases, particularly those associated with tissue damage and inflammation. The versatile functions of collagen, including skin regeneration, improving joint health, and increasing bone strength, make it potentially useful in treating different diseases. To the best of my knowledge, the strategy of using collagen to treat comorbid diseases has not been widely studied. This paper aims to explore the potential of collagen in treating comorbid diseases, including rheumatoid arthritis, osteoarthritis, osteoporosis, psoriatic arthritis, sarcopenia, gastroesophageal reflux, periodontitis, skin aging, and diabetes mellitus. Collagen-based therapies have shown promise in managing comorbidities due to their versatile properties. The multifaceted nature of collagen positions it as a promising candidate for treating complex diseases and addressing comorbid conditions. Its roles in wound healing, musculoskeletal disorders, cardiovascular health, and gastrointestinal conditions highlight the diverse therapeutic applications of collagen in the context of comorbidity management.

Abstract
Colonization and development of the gut microbiome are crucial for the growth and health of calves. In this review, we summarized the colonization, beneficial nutrition, immune function of gut microbiota, function of the gut barrier, and the evolution of core microbiota in the gut of calves of different ages. Homeostasis of gut microbiome is beneficial for nutritional and immune system development of calves. Disruption of the gut microbiome leads to digestive diseases in calves, such as diarrhea and intestinal inflammation. Microbiota already exists in the gut of calf fetuses, and the colonization of microbiota continues to change dynamically under the influence of various factors, which include probiotics, diet, age, and genotype. Colonization depends on the interaction between the gut microbiota and the immune system of calves. The abundance and diversity of these commensal microbiota stabilize and play a critical role in the health of calves.

Abstract
Chronic diseases, such as hypertension, cause great harm to human health. Conventional drugs have promising therapeutic effects, but also cause significant side effects. Food-sourced angiotensin-converting enzyme (ACE) inhibitory peptides are an excellent therapeutic alternative to pharmaceuticals, as they have fewer side effects. However, there is no systematic and effective screening method for ACE inhibitory peptides, and the lack of understanding of the sequence characteristics and molecular mechanism of these inhibitory peptides poses a major obstacle to the development of ACE inhibitory peptides. Through systematically calculating the binding effects of 160,000 tetrapeptides with ACE by molecular docking, we found that peptides with Tyr, Phe, His, Arg, and especially Trp were the characteristic amino acids of ACE inhibitory peptides. The tetrapeptides of WWNW, WRQF, WFRV, YYWK, WWDW, and WWTY rank in the top 10 peptides exhibiting significantly high ACE inhibiting behaviors, with IC50 values between 19.98 ± 8.19 μM and 36.76 ± 1.32 μM. Salt bridges, π-π stacking, π-cations, and hydrogen bonds contributed to the high binding characteristics of the inhibitors and ACE. Introducing eight Trp into rabbit skeletal muscle protein (no Trp in wide sequence) endowed the protein with a more than 90% ACE inhibition rate, further suggesting that meat with a high content of Trp could have potential utility in hypertension regulation. This study provides a clear direction for the development and screening of ACE inhibitory peptides.

Abstract
Modern consumer expectations have become highly diversified: they want more opportunities to meet diverse family needs (diversity of family members in age, gender, physical activity, etc. ,) and individual health goals with a huge variety of sensorial preferences. Our research is aimed to develop a protein-dense, highly bioactive, lactose- and whey protein-free beverage applying a central composite rotational design (CCRD) with 2 factors. For this purpose, an egg white-based beverage was flavored with mixed berries (factor A) and enriched with bovine collagen peptides (factor B). After suitable sample preparation, the rheological properties were investigated by an Anton Paar MCR 92 rheometer (with CC 27 system, and flow behavior was analyzed with a Herschel-Bulkley (H-B) model). The antioxidant capacity of samples was investigated by Ferric Reducing Antioxidant Power (FRAP) method, the total anthocyanin content was estimated based on a spectrophotometric method, and the total phenolic content was determined by the Folin Ciocalteu method. Our results are figured on response surfaces demonstrating that both factors and their interactions show a positive correlation with the examined parameters. Based on the CCRD, all investigated parameters are significantly influenced by at least one aspect and can be adequately estimated for further product development.

Abstract
PURPOSE We examined the effects of collagen peptides (CP) supplementation on exercise-induced gastrointestinal (GI) stress. METHODS In a randomized, crossover design, 20 volunteers (16 males: [Formula: see text]O2max, 53.4 ± 5.9 ml·kg-1) completed 3 trials: a non-exercise rest trial, with no supplement (REST) and then an exercise trial with CP (10 g·day-1) or placebo control (CON) supplements, which were consumed for 7 days prior to, and 45 min before, a 70 min run at 70-90% of [Formula: see text]O2max. Outcome measures included urinary lactulose and rhamnose (L/R), intestinal fatty acid binding protein (I-FABP), lipopolysaccharide (LPS), anti-LPS antibody, monocyte-chemoattractant protein-1 (MCP-1), interleukin (IL) 6 and 8, cortisol, alkaline phosphatase (ALP) (measured pre, 10 min post and 2 h post) and subjective GI symptoms. RESULTS There were no differences in heart rate, perceived exertion, thermal comfort, or core temperature during exercise in the CP and CON trials (all P > 0.05). I-FABP was higher in CP (2538 ± 1221 pg/ml) and CON (2541 ± 766 pg/ml) vs. REST 2 h post (1893 ± 1941 pg/ml) (both P < 0.05). LPS increased in CON vs. REST 2 h post (+ 71.8 pg/ml; P < 0.05). Anti-LPS antibody decreased in CON and CP vs. REST at post (both P < 0.05). There were no differences in MCP-1, IL-6, and IL-8 between the CP and CON trials (all P > 0.05), and no differences in L/R or GI symptoms between CON and CP (all P > 0.05). CONCLUSION Collagen peptides did not modify exercise-induced changes in inflammation, GI integrity or subjective GI symptoms but LPS was higher in CON 2 h post-exercise and thus future studies may be warranted.

Alterations in intestinal microbiota and metabolites in individuals with Down syndrome and their correlation with inflammation and behavior disorders in mice. Front Microbiol 2023; 14:1016872. [PMID: 36910172 PMCID: PMC9998045 DOI: 10.3389/fmicb.2023.1016872] [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: 08/11/2022] [Accepted: 02/06/2023] [Indexed: 02/25/2023] Open
Abstract
The intestinal microbiota and fecal metabolome have been shown to play a vital role in human health, and can be affected by genetic and environmental factors. We found that individuals with Down syndrome (DS) had abnormal serum cytokine levels indicative of a pro-inflammatory environment. We investigated whether these individuals also had alterations in the intestinal microbiome. High-throughput sequencing of bacterial 16S rRNA gene in fecal samples from 17 individuals with DS and 23 non-DS volunteers revealed a significantly higher abundance of Prevotella, Escherichia/Shigella, Catenibacterium, and Allisonella in individuals with DS, which was positively associated with the levels of pro-inflammatory cytokines. GC-TOF-MS-based fecal metabolomics identified 35 biomarkers (21 up-regulated metabolites and 14 down-regulated metabolites) that were altered in the microbiome of individuals with DS. Metabolic pathway enrichment analyses of these biomarkers showed a characteristic pattern in DS that included changes in valine, leucine, and isoleucine biosynthesis and degradation; synthesis and degradation of ketone bodies; glyoxylate and dicarboxylate metabolism; tyrosine metabolism; lysine degradation; and the citrate cycle. Treatment of mice with fecal bacteria from individuals with DS or Prevotella copri significantly altered behaviors often seen in individuals with DS, such as depression-associated behavior and impairment of motor function. These studies suggest that changes in intestinal microbiota and the fecal metabolome are correlated with chronic inflammation and behavior disorders associated with DS.

Abstract
Microbial infections and the slow regression of inflammation are major impediments to wound healing. Herein, a tilapia fish skin gelatin-fucose gum-tannic acid (Gel&Fuc-TA) hydrogel wound dressing (Gel&Fuc-TA) was designed to promote wound healing by mixing and reacting tannic acid (TA) with tilapia fish skin gelatin (Gel) and fucoidan (Fuc). Gel&Fuc-TA hydrogel has a good network structure as well as swelling and release properties, and shows excellent antibacterial, antioxidant, cell compatibility, and hemostatic properties. Gel&Fuc-TA hydrogel can promote the expression of vascular endothelial growth factor (VEGF), platelet endothelial cell adhesion molecule-1 (CD-31), and alpha-smooth muscle actin (α-SMA), enhance collagen deposition, and accelerate wound repair. Gel&Fuc-TA hydrogel can change the wound microbiome, reduce wound microbiome colonization, and decrease the expression of microbiome-related proinflammatory factors, such as lipopolysaccharide (LPS), Toll-like receptor 2 (TLR2), and Toll-like receptor 4 (TLR4). Gel&Fuc-TA hydrogel effectively regulates the conversion of wound macrophages to the M2 (anti-inflammatory phenotype) phenotype, decreases the expression of interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor-alpha (TNF-α), and increases the expression of arginase-1 (Arg-1), interleukin-10 (IL-10) and transforming growth factor-beta (TGF-β), thereby reducing the inflammatory response. In summary, Gel&Fuc-TA hydrogel prepared using a rational green cross-linking reaction can effectively accelerate wound healing.

Abstract
The gut microbiota is increasingly important in the overall human health and as such, it is a target in the search of novel strategies for the management of metabolic disorders including blood pressure, and cardiovascular diseases. The link between microbiota and hypertension is complex and this review is intended to provide an overview of the mechanism including the production of postbiotics, mitigation of inflammation, and the integration of food biological molecules within this complex system. The focus is on hydrolyzed food proteins and peptides which are less commonly investigated for prebiotic properties. The analysis of available data showed that food peptides are multifunctional and can prevent gut dysbiosis by positively affecting the production of postbiotics or gut metabolites (short-chain fatty acids, polysaccharides, biogenic amines, bile acids). Peptides and the postbiotics then displayed antihypertensive effects via the renin-angiotensin system, the gut barrier, the endothelium, and reduction in inflammation and oxidative stress. Despite the promising antihypertensive effect of the food peptides via the modulation of the gut, there is a lack of human studies as most of the works have been conducted in animal models.

Abstract
Mallotus oblongifolius (MO), which is rich in polyphenols, is a characteristic tea resource with medicinal value. In this study, a total of 45 polyphenolic components of MO, including narirutin, isoquercitrin, rutin and digallic acid, were identified by UPLC-Q-TOF/MS analysis. In addition, the gastroprotective effect of Mallotus oblongifolius polyphenols (MOP) on ethanol-induced gastric mucosal injury in rats was investigated. The rats received anhydrous ethanol after continuous gavage of MOP or lansoprazole for one week. In addition, the macro- and micro-damage induced by ethanol in the gastric tissue was significantly reduced after MOP pretreatment for one week. Further analysis showed that MOP prevented ethanol-induced acute gastric mucosal injury by increasing the expression of antioxidant enzymes (SOD, CAT, GSH-Px) and decreasing the expression of reactive oxygen species (ROS), lipid oxidation product (MDA) and myeloperoxidase (MPO). Meanwhile, MOP inhibited the phosphorylation of p38/ERK/JNK and promoted the activation of the Nrf2 pathway. These results suggested that MOP may be a promising therapeutic target for the prevention of ethanol-induced gastric mucosal injury by improving oxidative stress, inhibiting the p38/ERK/JNK signaling pathways and activating Nrf2 expression.

Abstract
Collagen-tripeptide (CTP) and galacto-oligosaccharide (GOS), which improve collagen homeostasis and barrier function in the skin, are widely used in the food industry to improve wrinkle-related parameters and skin health. In this study, the photoprotective effect of CTP/GOS mixtures (3:1, 1:1, and 1:3) in ultraviolet (UV) B-irradiated hairless mice was examined. Skin parameter analysis, histological approaches, molecular biology techniques and HPLC analysis were applied to investigate the photoaging protective effect, signaling pathways and changes in the microbiota. Oral administration of CTP/GOS mixtures ameliorated photoaged physical parameters and serum levels of pro-inflammatory cytokines compared to UV-irradiated control group. Administration of the 1:3 mixture showed significant changes in the extracellular matrix-related gene expression compared to other mixture groups. The cecal short-chain fatty acid (SCFA) content showed a significant increase in the CTP/GOS mixed group with a higher GOS content than the control group. In the 16S rRNA-based analysis of cecal microbiota, the relative abundance ratio of the Akkermansia genus belonging to the Verrucomicrobia phylum was higher in CTP and GOS mixture-administered groups than in the UV-irradiated control group. Taken together, CTP/GOS mixtures showed a synergistic effect on photoprotective activity through changes in the gene expression, cytokine levels and intestinal microbiota composition.

Abstract
Whey protein and its hydrolysate are ubiquitously consumed as nutritional supplements. This study aimed to evaluate the potential effect of whey protein hydrolysate (WPH) on the infant gut microbiome, which is more variable than that of adults. Colonic fermentation was simulated through a static digestion model and fecal culture fermentation, using feces from normal infants aged from 1−3 years old. During in vitro gut fermentation, measurements of short-chain fatty acids (SCFA) concentrations and 16S rRNA amplicon sequencing were performed. Additionally, the growth curves of cultivated probiotics were analyzed to evaluate the prebiotic potential of WPH. Besides the decline of pH in fermentation, the addition of WPH induced a significant increase in the SCFA production and also the relative abundance of Proteobacteria, Bacteroides, and Streptococcus (p < 0.05). The lower ratio of Firmicutes/Bacteroidetes in WPH-supplemented samples indicated the positive modulation of WPH on the gut microbiota, which could benefit the energy balance and metabolism of infants. The stimulation effect of WPH on the probiotics (particularly Lactobacillus acidophilus NCFM) during cultivation implied the prebiotic potential as well. Our findings shed light on WPH as a valuable dietary supplement with not only enriched resources of essential amino acids but also the potential to restore the infant gut microbiome.

Abstract
BACKGROUND In folk medicine Coptis chinensis Franch (Huanglian in Chinese, HL) and Magnoliae officinalis (Houpo, HP) have been used to treat gastrointestinal disorders over hundreds of years, such as ulcers and inflammation. PURPOSE To investigate the therapeutic effects of HL and HP on 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced ulcerative colitis (UC) rats, and investigated its effect on the intestinal flora of UC rats. METHOD TNBS 40 mg/kg was utilized to establish UC model. Rats were sacrificed after gavage for 7 days. Body weight loss, disease activity index (DAI), colonic mucosal damage index (CMDI) and histopathology were measured. Intestinal content samples were collected, and analyzed by 16 S rRNA sequencing. Western blot, immunohistochemistry and real-time polymerase chain reaction were used to evaluate the regulation mechanism of HL+HP in UC model rats. RESULTS The results showed that the DAI score, CMDI score and histological score were significantly decreased in each group. The symptoms of diarrhea, hematochezia, colonic mucosal injury and congestion and edema were improved. Sequencing results of intestinal flora showed that the abundance of probiotics such as Akkermansia and Blautia was increased in HL group and HL+HP group, while probiotics such as Allobaculum and Alloprevotella were increased in HP group. The intestinal pathogenic bacteria such as Escherichia-Shigella and Clostridium_sensu_stricto_1 were decreased. In addition, HL+HP could also inhibit the inflammatory response and protect the integrity of the tight junction to play an anti-UC effect. CONCLUSION Coptis chinensis Franch and Magnolia officinalis might prevent intestinal barrier damage by regulating intestinal flora imbalance and inhibit the inflammatory response.

Abstract
Intestinal microbiota and metabonomics were integrated to investigate the efficiency of non-saponification or saponification astaxanthin (N-Asta or S-Asta) derived from Penaeus sinensis by-products on alleviating paracetamol (PCM)-induced oxidative stress. Pre-treatment with N-Asta or S-Asta for 14 days restored the cellular morphology of the intestine and increased glutathione (GSH) levels under PCM overdose in rats. However, S-Asta displayed higher adsorption than that of N-Asta. PCM overdose reduced the richness and diversity of intestinal microbiota in the model group. Comparably, N-Asta or S-Asta pre-treatment increased the Actinobacteria abundance. Increased phyla Bacteroidetes and Verrucomicrobia were only found in the S-Asta-pre-treated group. At the genus level, N-Asta pre-treatment increased Lactobacillus and Parasutterella abundance, whereas S-Asta pre-treatment elevated Bacteroidales_S24-7_group_norank and Ruminococcaceae_uncultured. Compared to the control and model groups, remarkable increases of fecal short-chain fatty acids were detected in both N-Asta and S-Asta pre-treatment groups, suggesting the contribution of N-Asta and S-Asta adsorption to SCFA-producing bacteria enrichment. Furthermore, the genera of Ruminococcaceae_uncultured, Ruminiclostridium_9, Ruminococcaceae_unclassified and Ruminococcus_1 showed high correlations with propionic acid, isobutyric acid, butyric acid, isovaleric acid and valeric acid increases in the S-Asta pre-treated group. Seventeen plasma biomarker metabolites in more than 10 metabolic pathways were responsible for the difference between the N-Asta and S-Asta pre-treated groups. Metabolites GSH, retinol, all-trans-Retinoic acid and taurine related to antioxidant activities were significantly accumulated in the S-Asta pre-treated group, while increasing taurocholic acid levels associated with the anti-inflammatory activity was found in the N-Asta-pre-treated group. Therefore, N-Asta and S-Asta could have potential applications in counterbalancing intestinal flora and metabolite disturbances by overdose chemical induction.

Abstract
The human intestine hosts diverse microbial communities that play a significant role in maintaining gut-skin homeostasis. When the relationship between gut microbiome and the immune system is impaired, subsequent effects can be triggered on the skin, potentially promoting the development of skin diseases. The mechanisms through which the gut microbiome affects skin health are still unclear. Enhancing our understanding on the connection between skin and gut microbiome is needed to find novel ways to treat human skin disorders. In this review, we systematically evaluate current data regarding microbial ecology of healthy skin and gut, diet, pre- and probiotics, and antibiotics, on gut microbiome and their effects on skin health. We discuss potential mechanisms of the gut-skin axis and the link between the gut and skin-associated diseases, such as psoriasis, atopic dermatitis, acne vulgaris, rosacea, alopecia areata, and hidradenitis suppurativa. This review will increase our understanding of the impacts of gut microbiome on skin conditions to aid in finding new medications for skin-associated diseases.

Abstract
Inflammatory bowel disease is associated with intestinal homeostasis dysregulation and gut microbiota dysbiosis. This study aimed to investigate the protective effect of Ganoderma applanatum extracts (G. applanatum polysaccharides (GAP) and 75% ethanol extracts (GAE)) on colon inflammation and elucidate the therapeutic mechanism. GAP and GAE showed considerable protective effects against dextran sodium sulfate (DSS)-induced colitis, as demonstrated by reduced mortality, body weight, disease activity index score, colon length, and histological score. Through GAP and GAE administration, the destroyed intestinal barrier recovered to normal, as did intestinal inflammation. We also confirmed that GAP administration promoted the recovery of colitis in a gut microbiota-dependent manner. The similarity between GAP and GAE administration was that they both altered the disordered gut microbiota damaged by DSS, exhibiting reduced abundance of Escherichia_Shigella, Enterococcus, and Staphylococcus, but the modulation of the gut microbiota was distinct between GAP and GAE.

Abstract
The destruction of the homeostasis in the gut-brain axis can lead to cognitive impairment and memory decline. Dietary intervention with bioactive peptides from aquatic products is an innovative strategy to prevent cognitive deficits. The present study aimed to determine the neuroprotective effect of tilapia head protein hydrolysate (THPH) on scopolamine-induced cognitive impairment in mice, and to further explore its mechanism through the microbiota–gut-brain axis. The results showed that THPH administration significantly improved the cognitive behavior of mice, and normalized the cholinergic system and oxidative stress system of the mice brain. The histopathological observation showed that THPH administration significantly reduced the pathological damage of hippocampal neurons, increased the number of mature neurons marked by NeuN and delayed the activation of astrocytes in the hippocampus of mice. In addition, THPH administration maintained the stability of cholinergic system, alleviated oxidative stress and further improved the cognitive impairment by reshaping the gut microbiota structure of scopolamine-induced mice and alleviating the disorder of lipid metabolism and amino acid metabolism in serum. In conclusion, our research shows that THPH supplementation is a nutritional strategy to alleviate cognitive impairment through the gut-brain axis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Jiao Sanxian, a customary term for the three Traditional Chinese Medicines of charred hawthorn (Crataegi Fructus), charred malt (Hordei Fructus Germinatus) and Liu Shenqu (Massa Medicata Fermentata), is a classic prescription for the treatment of functional dyspepsia (FD). This prescription is called "Jiao Sanxian" in China because people believe that it is a miracle medicine for enhancing digestion and improving stagnation of digestive system. Even though Jiao Sanxian is widely used in clinical treatment, the underlying mechanism has not been clarified to date. AIM OF THE STUDY The present study is aimed to explore the efficacy and mechanism of Jiao Sanxian in improving the symptoms of FD in rats by using multiple pharmacological methods. MATERIALS AND METHODS The Sprague Dawley (SD) rats were divided into control, model, Jiao Sanxian decoction low-dosage (JSXD LD), Jiao Sanxian decoction medium-dosage (JSXD MD), and Jiao Sanxian decoction high-dosage (JSXD HD) group at random. A FD model was established with reserpine, and animals were given intragastric administration. During this period, weight and food intake of animals were recorded. Samples of rat gastric antrum, spleen, and duodenum were collected for pathological staining and immunohistochemical determination of Ghrelin protein expression after 19 days of treatment. Enzyme-linked immunosorbent assay (ELISA) was used to determine the concentration of related brain gut peptides in serum. Moreover, 16S rRNA sequencing was used to valuate the influence of intestinal flora structure of the cecal contents of experimental rats. And plasma metabolomics by Ultra Performance Liquid Chromatography coupled with Quadrupole-Time-of-Flight mass spectrometry (UPLC-Q/TOF-MS) were performed to further reveal the mechanism of action. RESULTS Jiao Sanxian decoction (JSXD) group with different dosage could increase body weight and food intake, improve histopathological changes, and alter disordered brain gut peptides in FD rats. 16S rRNA sequencing results described that JSXD improved the disorder of structural composition, biodiversity and function of gut microbiota in FD rats. Metabolomics illustrated 26 metabolites with JSXD treatment underwent continuous changes, which revealed JSXD might exert digestive effect by ameliorating abnormal metabolic pathways. The most relevant metabolic pathways were arachidonic acid metabolism, pyruvate metabolism, glycerophospholipid metabolism, alanine, aspartate and glutamate metabolism. CONCLUSIONS JSXD can improve functional dyspepsia in rats and the mechanism is related to regulate secretion of brain gut peptides, significantly improve the disorder of intestinal flora and ameliorated multi-metabolic pathways.

Abstract
Aging is a biological process that occurs under normal conditions and in several chronic degenerative diseases. Bioactive natural peptides have been shown to improve the effects of aging in cell and animal models and in clinical trials. However, few reports delve into the enormous diversity of peptides from marine organisms. This review provides recent information on the antiaging potential of bioactive peptides from underused marine resources, including examples that scavenge free radicals in vitro, inhibit cell apoptosis, prolong the lifespan of fruit flies and Caenorhabditis elegans, suppress aging in mice, and exert protective roles in aging humans. The underlying molecular mechanisms involved, such as upregulation of oxidase activity, inhibition of cell apoptosis and MMP-1 expression, restoring mitochondrial function, and regulating intestinal homeostasis, are also summarized. This work will help highlight the antiaging potential of peptides from underused marine organisms which could be used as antiaging foods and cosmetic ingredients in the near future.

Abstract
In 2020, the world's food crisis and health industry ushered into a real outbreak. On one side, there were natural disasters such as the novel coronavirus (2019-nCoV), desert locusts, floods, and droughts exacerbating the world food crisis, while on the other side, the social development and changes in lifestyles prompted the health industry to gradually shift from a traditional medical model to a new pattern of prevention, treatment, and nourishment. Therefore, this article reviews animal by-products collagen and derived peptide, as important components of innovative sustainable food systems. The review also considered the preparation, identification, and characterization of animal by-product collagen and collagen peptides as well as their impacts on the food system (including food processing, packaging, preservation, and functional foods). Finally, the application and research progress of animal by-product collagen and peptide in the food system along with the future development trend were discussed. This knowledge would be of great significance for a comprehensive understanding of animal by-product collagen and collagen peptides and would encourage the use of collagen in food processing, preservation, and functional foods.
