- BACKGROUND: The suckling period in pigs is a key phase in development for shaping the gut microbiota, which is essential for maintaining biological homeostasis in neonates. In piglets fed sow milk, the gut microbiota comprises predominantly lactobacilli, indicating a host-gut microbiota symbiosis that is influenced by sow milk components. In this study, we sought to elucidate the mechanisms underlying the establishment and maintenance of the gut microbiome in suckling piglets, with a specific focus on the metabolism of sialyl-oligosaccharides by lactobacilli. RESULTS: Based on liquid chromatography-mass spectrometry analysis, we identified 3'-sialyl-lactose (3'SL) as the major oligosaccharide in porcine milk, and microbiome profiling revealed the predominance of Ligilactobacillus salivarius during the suckling period, with a subsequent transition to Limosilactobacillus reuteri dominance post-weaning. Notably, sialic acid metabolism was established to be exclusively attributable to L. salivarius, thereby highlighting the pivotal role of 3'SL in determining species-specific bacterial segregation. L. salivarius was found to metabolize 3'SL when co-cultured with Bacteroides thetaiotaomicron, resulting in a shift in the predominant short-chain fatty acid produced, from lactate to acetate. This metabolic shift, in turn, inhibits the growth of enterotoxigenic Escherichia coli. Furthermore, the comparison of the gut microbiota between suckling piglets and those fed a low-3'SL formula revealed distinct diversity profiles. We accordingly speculate that an absence of sialyl-oligosaccharides in the formula-fed piglets may have restricted the growth of sialic acid-utilizing bacteria such as L. salivarius, thereby leading to a higher abundance of Enterobacteriaceae. CONCLUSIONS: Our findings reveal the influence of sialyl-oligosaccharides in promoting microbial diversity and gut homeostasis, thereby highlighting the importance of sialic acid as a key factor in shaping milk-driven microbial colonization during the early stages of piglet development.

- In this era of pandemics, reducing the risk of lifestyle-related diseases (LRD) by functional foods is of paramount importance. The conventional process of functional food development almost invariably involves in vitro, animal, and human intervention trials, but differences in intestinal environments between humans and experimental animals make it difficult to develop functional foods that are truly effective in humans. Thus, it is necessary to construct a model that simulates the human intestinal environment to evaluate the functionality of any food component before subjecting it to a human intervention trial. In this review, we provide an overview of a model simulating human intestinal microbiota constructed at Kobe University and its use as a tool to identify food components that contribute to the prevention and treatment of LRD.2024年03月, Current opinion in biotechnology, 87, 103103 - 103103
- Efficient cold-chain delivery is essential for maintaining a sustainable global food supply. This study used metabolomic analysis to examine meat quality changes during the "wet aging" of crossbred Wagyu beef during cold storage. The longissimus thoracic (Loin) and adductor muscles (Round) of hybrid Wagyu beef, a cross between the Japanese Black and Holstein-Friesian breeds, were packaged in vacuum film and refrigerated for up to 40 days. Sensory evaluation indicated an increase in the umami and kokumi taste owing to wet aging. Comprehensive analysis using gas chromatography-mass spectrometry identified metabolite changes during wet aging. In the Loin, 94 metabolites increased, and 24 decreased; in the Round, 91 increased and 18 decreased. Metabolites contributing to the umami taste of the meat showed different profiles during wet aging. Glutamic acid increased in a cold storage-dependent manner, whereas creatinine and inosinic acid degraded rapidly even during cold storage. In terms of lipids, wet aging led to an increase in free fatty acids. In particular, linoleic acid, a polyunsaturated fatty acid, increased significantly among the free fatty acids. These results provide new insight into the effects of wet aging on Wagyu-type beef, emphasizing the role of free amino acids, organic acids, and free fatty acids generated during cold storage.2024年01月, Metabolites, 14(2) (2)
- Hyaluronan (HA) is a high-molecular-weight glycosaminoglycan and widely distributed in all connective tissues and organs with diverse biological functions. HA has been increasingly used as dietary supplements targeted to joint and skin health for humans. We here first report isolation of bacteria from human feces that are capable of degrading HA to lower molecular weight HA oligosaccharides (oligo-HAs). The bacteria were successfully isolated via a selective enrichment method, in which the serially diluted feces of healthy Japanese donors were individually incubated in an enrichment medium containing HA, followed by the isolation of candidate strains from streaked HA-containing agar plates and selection of HA-degrading strains by measuring HA using an ELISA. Subsequent genomic and biochemical assays identified the strains as Bacteroides finegoldii, B. caccae, B. thetaiotaomicron, and Fusobacterium mortiferum. Furthermore, our HPLC analysis revealed that the strains degraded HA to oligo-HAs of various lengths. Subsequent quantitative PCR assay targeting the HA degrading bacteria showed that their distribution in the Japanese donors varied. The evidence suggests that dietary HA is degraded by the human gut microbiota with individual variation to oligo-HAs components, which are more absorbable than HA, thereby exerting its beneficial effects.2023年, PloS one, 18(5) (5), e0284517
- Japanese Black cattle (Japanese Wagyu) beef is attracting attention for its aroma and marbling, and its handling is increasing worldwide. Here, we focused on the origin discrimination of Wagyu beef and analyzed the nutritional components of Japanese Wagyu (produced in multiple prefectures of Japan), Hybrid Wagyu (a cross between Angus and Wagyu cattle born in Australia and transported to Japan), and Australian Wagyu beef using mass spectrometry (MS). Triple-quadrupole liquid chromatography–MS was used to clarify the molecular species of lipids in Wagyu beef. Fourteen classes of lipids were separated, and 128 different triacylglycerides (TGs) were detected. A simple comparative analysis of these TGs using high-performance liquid chromatography revealed significantly higher levels of triolein (C18:1/C18:1/C18:1; abbreviated OOO) and C18:1/C18:1/C16:1 (OOPo) in Japanese Wagyu. Wagyu elements beef were comprehensively analyzed using inductively coupled plasma (ICP)–MS and ICP–optical emission spectrometry. We found significant differences in the rubidium, cesium, and lithium levels of Japanese and Australian Wagyu beef. On comparing metabolites using gas chromatography–MS, we identified significant differences in the levels of amino acids and other components of the Japanese and Australian Wagyu beef. These results suggest the possibility of determining the origin of Wagyu cattle breeds using MS and genetic discrimination.MDPI AG, 2022年08月, Metabolites, 12(9) (9), 777 - 777
- The strawberry fruit contains abundant polyphenols, such as anthocyanins, flavan-3-ol, and ellagitannin. Polyphenol enrichment improves the quality of strawberries and leads to a better understanding of the polyphenol induction process. We measured the total polyphenol content of strawberry fruits under different growth conditions, developmental stages, and treatment conditions during pre-harvest and post-harvest periods. High fruit polyphenol content was observed in cold treatment, which was selected for further analysis and optimization. A transcriptome analysis of cold-treated fruits suggested that the candidate components of polyphenols may exist in the phenylpropanoid pathway. Coverage with a porous film bag excluded the effects of drought stress and produced polyphenol-rich strawberry fruits without affecting quality or quantity. The degree of stress was assessed using known stress indicators. A rapid accumulation of abscisic acid was followed by an increase in superoxide dismutase and DPPH (2,2-Diphenyl-1-picrylhydrazyl) activity, suggesting that the strawberry fruits responded to cold stress immediately, reaching the climax at around 6 days, a trend consistent with that of polyphenol content. These findings enhance our understanding of the mechanism of post-harvest polyphenol accumulation and the value of strawberries as a functional food.MDPI AG, 2022年, Plants, 11(17) (17), 17 (13 pages) - 2220

- We report the isolation of bacteria capable of degrading milk oligosaccharides from suckling infant rats. The bacteria were successfully isolated via a selective enrichment method, in which the serially diluted intestinal contents of infant rats were individually incubated in an enrichment medium containing 3'-sialyllactose (3'-SL), followed by the isolation of candidate strains from streaked agar plates and selection of 3'-SL-degrading strains using thin-layer chromatography. Subsequent genomic and phenotypic analyses identified all strains as Enterococcus gallinarum. The strains were capable of degrading both 3'-SL and 6'-SL, which was not observed with the type strain of E. gallinarum used as a reference. Furthermore, a time-course study combining high-performance anion-exchange chromatography with pulsed amperometric detection revealed that the representative strain AH4 degraded 3'-SL completely to yield an equimolar amount of lactose and an approximately one-fourth equimolar amount of sialic acid after 24 hr of anaerobic incubation. These findings point to a possibility that the enterococci degrade rat milk oligosaccharides to "cross-feed" their degradants to other members of concomitant bacteria in the gut of the infant rat.2021年, Bioscience of microbiota, food and health, 40(1) (1), 27 - 32
- We investigated bacteria that have a nutritional symbiotic relationship with respect to milk oligosaccharides in gut microbiota of suckling rats, with specific reference to sialyllactose (SL) degrading Enterococcus gallinarum. Our next generation sequencing analysis of the colonic contents of 12-day-old suckling rats revealed that almost half of the bacteria in the microbiota belonged to the Lactobacillaceae family. Major Lactobacillus species in the contents were identified as L. johnsonii, L. murinus, and L. reuteri. We then monitored changes in numbers of the above Lactobacillus species, E. gallinarum, and the bacteria belonging to the family Enterobacteriaceae (i.e., enterobacteria) in the colonic contents of infant rats at 7, 12, 21, 28, and 35 days of age by using real-time PCR assays targeting these bacterial groups. The 7-day-old infant rats had a gut microbiota in which enterobacteria were predominant. Such dominance was replaced by L. johnsonii and the concomitant E. gallinarum markedly increased in those of 12 and 21 days of ages. During this period, the number of enterobacteria declined dramatically, but that of L. reuteri surged dramatically. Our separate in vitro experiment showed that supplementation of culture media with SL promoted the growth of L. johnsonii and E. gallinarum, with marked production of lactic acid. These findings revealed possible milk oligosaccharide-mediated cross-feeding between E. gallinarum and L. johnsonii, with the former degrading SL to release lactose to be utilized by the latter.2021年, Bioscience of microbiota, food and health, 40(4) (4), 204 - 211
- Extracellular proteins are important factors in host-microbe interactions; however, the specific factors that enable bifidobacterial adhesion and survival in the gastrointestinal (GI) tract are not fully characterized. Here, we discovered that Bifidobacterium longum NCC2705 cultured in bacterium-free supernatants of human fecal fermentation broth released a myriad of particles into the extracellular environment. The aim of this study was to characterize the physiological properties of these extracellular particles. The particles, approximately 50 to 80 nm in diameter, had high protein and double-stranded DNA contents, suggesting that they were extracellular vesicles (EVs). A proteomic analysis showed that the EVs primarily consisted of cytoplasmic proteins with crucial functions in essential cellular processes. We identified several mucin-binding proteins by performing a biomolecular interaction analysis of phosphoketolase, GroEL, elongation factor Tu (EF-Tu), phosphoglycerate kinase, transaldolase (Tal), and heat shock protein 20 (Hsp20). The recombinant GroEL and Tal proteins showed high binding affinities to mucin. Furthermore, the immobilization of these proteins on microbeads affected the permanence of the microbeads in the murine GI tract. These results suggest that bifidobacterial exposure conditions that mimic the intestine stimulate B. longum EV production. The resulting EVs exported several cytoplasmic proteins that may have promoted B. longum adhesion. This study improved our understanding of the Bifidobacterium colonization strategy in the intestinal microbiome.IMPORTANCE Bifidobacterium is a natural inhabitant of the human gastrointestinal (GI) tract. Morphological observations revealed that extracellular appendages of bifidobacteria in complex microbial communities are important for understanding its adaptations to the GI tract environment. We identified dynamic extracellular vesicle (EV) production by Bifidobacterium longum in bacterium-free fecal fermentation broth that was strongly suggestive of differing bifidobacterial extracellular appendages in the GI tract. In addition, export of the adhesive moonlighting proteins mediated by EVs may promote bifidobacterial colonization. This study provides new insight into the roles of EVs in bifidobacterial colonization processes as these bacteria adapt to the GI environment.2020年09月, Applied and environmental microbiology, 86(19) (19)
- Microbial production of butyrate is impaired in patients with ulcerative colitis (UC); however, this inhibition is not well understood in Japanese UC patients. Therefore, we quantitatively analyzed genes encoding butyryl-CoA:acetate CoA-transferase (but) and butyrate kinase (buk) in the gut microbiota of Japanese patients with UC and healthy volunteers (HVs). But showed higher levels than buk. Moreover, patients with UC showed significantly decreased levels of but associated with Roseburia sp./Eubacterium rectale compared with HVs. But, which is associated with Faecalibacterium sp., was maintained in patients with UC, with an unchanged relative abundance of Faecalibacterium sp. microorganisms in patients with UC compared with HVs.2019年10月, Bioscience of Microbiota, Food and Health, 38(4) (4), 159 - 163
- Compositional alteration of the gut microbiota is associated with ulcerative colitis (UC). Here, a model culture system is established for the in vitro human colonic microbiota of UC, which will be helpful for determining medical interventions. 16S ribosomal RNA sequencing confirms that UC models are successfully developed from fecal inoculum and retain the bacterial species biodiversity of UC feces. The UC models closely reproduce the microbial components and successfully preserve distinct clusters from the healthy subjects (HS), as observed in the feces. The relative abundance of bacteria belonging to the family Lachnospiraceae significantly decreases in the UC models compared to that in HS, as observed in the feces. The system detects significantly lower butyrogenesis in the UC models than that in HS, correlating with the decreased abundance of Lachnospiraceae. Interestingly, the relative abundance of Lachnospiraceae does not correlate with disease activity (defined as partial Mayo score), suggesting that Lachnospiraceae persists in UC patients at a decreased level, irrespective of the alteration in disease activity. Moreover, the system shows that administration of Clostridium butyricum MIYAIRI restores butyrogenesis in the UC model. Hence, the model detects deregulation in the intestinal environment in UC patients and may be useful for simulating the effect of probiotics.2019年, Biotechnology Journal, 14(5) (5), e1800555

- Poly (ADP-ribose) polymerase family, member 1 (Parp1) has pleiotropic and disparate functions in multiple cellular signaling pathways through post-translational protein modification. It contributes to the regulation of various cellular processes, including DNA damage repair, cell death, and cell differentiation, genetically or epigenetically. Meanwhile, the functions of Parp1 in intercellular signaling remain to be established. To examine the functions of Parp1 in intercellular signaling, we examined microRNA (miRNA) regulation in exosomes derived from Parp1-deficient (Parp1-/-) embryonic stem (ES) cells. The percentages of miRNAs among total RNAs, including small RNAs such as miRNAs, snRNAs, snoRNAs, tRNAs, exonic RNAs, and intronic RNAs, in Parp1+/+ and Parp1-/- ES cell-derived exosomes were 8.2% and 3.5%, respectively. Overall, 329 distinct miRNAs exhibited ≥2-fold changes (118 upregulated; 211 downregulated). The upregulated miRNAs targeted 810 candidate genes, and the downregulated miRNAs targeted 716 candidate genes. Pathway analyses revealed that the upregulated miRNAs were significantly associated with five pathways including MAPK signaling cascades (p < 0.05), indicating that the target genes in these pathways were suppressed in Parp1-/- ES cells. In quantitative analyses of miRNA expression, miR365-3p, let-7a-5p, miR196b-5p, miR203-3p, miR98-5p, and miR146a-5p were increased by ≥ 2-fold in Parp1-/- ES cell-derived exosomes. Gene ontology enrichment analyses revealed that the upregulated miRNAs were significantly annotated for growth and stress-related cell signaling and cell communication (p < 0.05). Parp1 deficiency in ES cells led to inhibition of cell-cell communication, possibly by intercellular signal transduction, suggesting that Parp1 functions extracellularly by regulating exosomal miRNAs.2018年05月, Biochemical and biophysical research communications, 499(3) (3), 410 - 415
- Accumulating evidence suggests that dietary taurine (2-aminoethanesulfonic acid) exerts beneficial anti-inflammatory effects in the large intestine. In this study, we investigated the possible impact of taurine on human colonic microbiota using our single-batch fermentation system (Kobe University Human Intestinal Microbiota Model; KUHIMM). Fecal samples from eight humans were individually cultivated with and without taurine in the KUHIMM. The results showed that taurine remained largely undegraded after 30 h of culturing in the absence of oxygen, although some 83% of the taurine was degraded after 30 h of culturing under aerobic conditions. Diversity in bacterial species in the cultures was analyzed by 16S rRNA gene sequencing, revealing that taurine caused no significant change in the diversity of the microbiota; both operational taxonomic unit and Shannon-Wiener index of the cultures were comparable to those of the respective source fecal samples. In addition, principal coordinate analysis indicated that taurine did not alter the composition of bacterial species, since the 16S rRNA gene profile of bacterial species in the original fecal sample was maintained in each of the cultures with and without taurine. Furthermore, metabolomic analysis revealed that taurine did not affect the composition of short-chain fatty acids produced in the cultures. These results, under these controlled but artificial conditions, suggested that the beneficial anti-inflammatory effects of dietary taurine in the large intestine are independent of the intestinal microbiota. We infer that dietary taurine may act directly in the large intestine to exert anti-inflammatory effects.2017年, PloS one, 12(7) (7), e0180991
