作者： Ge Song Shaojie Pang Wenting Peng Wei Fang Yong Wang Rui Liu Qianyun Gan Wentao Qi Academy of National Food and Strategic Reserves Administration department of Nutrition and Food hygiene School of Public Health Peking University School of Health Science and Engineering University of Shanghai for Science and technology

Background: Fructose may induce non-alcoholic fatty acids (NAFLD) due to the gut-liver axis interactions. The mechanism of fructose impairing colon barrier is unrevealed. Methods: Normal and DSS-induced Sprague-Dawley rats fed by 35% fructose diets were used to evaluate colon barrier functions. Microbiome and metabolome were applied to screen potential biomarker bacteria and metabolites induced by fructose. HT-29 cells were applied to validate metabolite biomarker indoleacrylic acid (IAA) and indole-3-carboxaldehyde (I3A) function in colon barrier which impaired by fructose. Results: Fructose induced colon barrier dysfunction， aggravated colon impairment in DSS-induced rats. With fructose intake， the colon length shortened， goblet numbers declined， inflammation infiltration induced， inflammatory cytokines increased， and apoptosis signals upregulated in colon tissue. Moreover， fructose induced dysbiosis of microbiota and their metabolites. Adlercreutzia， Holdemania were screened out as potential bacteria biomarkers， IAA and I3A as tryptophan metabolites were selected as metabolite biomarkers inhibited by fructose. IAA and I3A treatment alleviated the impairment induced by fructose by increasing trans epithelial electric resistance (TEER) value， tight junction proteins (TJPs)， and AhR activity in HT-29 cell. Conclusion: Fructose stimulated inflammation， apoptosis， gut bacteria alteration， and induced the reduction of IAA and I3A. Since fructose inhibited production of IAA and I3A， AhR remained inactivated and consequently induced colon barrier dysfunction.

Alzheimer's disease （AD） has become an important public health issue worldwide. P-Coumaric acid （CA） and lactoferrin （Lf） possessed antioxidant， anti-inflammatory， and anti-AD activities. Herein， we hypothesized that a combination treatment of CA and Lf would synergistically improve AD symptoms and studied its mechanisms. Twelve-week-old APP/PS1 mice were treated with CA， Lf， or both CA and Lf for 8 weeks. Results showed that individual and combined treatments could ameliorate cognitive deficits to varying degrees， with stronger effects for combined intervention than for CA or Lf alone. Specifically， combined treatment was most effective in improving nesting ability and reducing Aβ1-42deposition in mice. Moreover， combined treatment was more effective in suppressing APP， BACE1， and inflammation; it inhibited the CCAAT-enhancer-binding protein （C/EBPβ）/asparagine endopeptidase （AEP） signaling pathway in the hippocampus and colon and upregulated the expression of tight junction protein ZO-1 in the colon; it also decreased the F/B ratio at the phylum level and increased the relative abundance of Prevotellaceae， Lachnospira， and Eubacterium at the genus level. Overall， the combination of CA and Lf may ameliorate cognitive deficits in APP/PS1 mice by improving inflammation and inhibiting the C/EBPβ/AEP signaling pathway via modulating gut microbiome.

Dietary yeast extract prevents alcoholic liver disease in mice via correcting gut dysbiosis and improving intestinal barrier function

Food Science and Human Wellness 2024年

作者： Hao Han Lei Tian Yajing Dong Yanyang Han Xiaoman Wang Qian Cheng Haibo Zhang Yan Zhang department of Nutrition and Food hygiene School of Public Health Shanxi medical University Hubei Provincial Key Laboratory of Yeast Function Research Center of Nutrition and Health Food Yichang School of Health Science and Engineering Shanghai Engineering Research Center of Food Microbiology University of Shanghai for Science and technology

Alcoholic liver disease (ALD) is one of the major global public health problems. Yeast extract (YE)， a product prepared from yeast， has been proven to have antioxidant and anti-inflammatory properties. However， the potential role of YE in the prevention of ALD remains unclear. The present study aimed to investigate the protective effects of YE on ALD and explore the underlying mechanism based on gut microbiota. The result showed that YE supplementation significantly ameliorated chronic alcohol exposure-induced liver injury in mice. In addition， YE counteracted alcohol-induced gut dysbiosis， intestinal barrier dysfunction， lipopolysaccharide (LPS) leakage-induced inflammatory response in the liver. Moreover， microbiota depletion by a broad-spectrum antibiotic was sufficient to block the protective effect of YE on ALD， indicating the contribution of gut dysbiosis modulation to the hepatoprotective role of YE. Furthermore， we demonstrated the causal relationship between gut microbiota and hepatoprotective effects of YE with the fecal microbiota transplantation (FMT) experiment. Compared with the ALD-FMT mice， gut dysbiosis， intestinal barrier dysfunction， LPS/TLR4 signaling pathway activation， and liver inflammatory response were significantly improved in the YE-FMT mice. Together， our findings highlight that dietary YE protects against ALD through gut dysbiosis correction.
