Researchers investigated mulberry anthocyanin extract in high-fat, high-cholesterol diet-fed mice and found it reduced LDL cholesterol and inflammatory markers while favorably shifting gut microbial composition and modulating liver metabolites including glutamine and ATP, suggesting a mechanism linking gut microbiota to atherosclerosis risk reduction.
A probiotic for preventing microplastic toxicity: Clostridium dalinum mitigates microplastic-induced damage via microbiota-metabolism-barrier interactions
Using metagenomics and metabolomics, this study found that the probiotic bacterium Clostridium dalinum reduced microplastic-induced gut damage in mice by modulating gut microbiota composition, metabolic pathways, and intestinal barrier integrity.
Deciphering Microbiome, Transcriptome, and Metabolic Interactions in the Presence of Probiotic Lactobacillus acidophilus against Salmonella Typhimurium in a Murine Model
Researchers tested whether the probiotic Lactobacillus acidophilus could protect mice against Salmonella Typhimurium infection by examining changes in gut bacteria, gene expression, and metabolic pathways. They found that probiotic treatment improved gut microbial balance, reduced harmful bacterial load, and modulated immune and metabolic responses. The study suggests that probiotics may offer a promising alternative strategy to antibiotics for managing certain foodborne bacterial infections.
Gut Check: Microbiota and Obesity in Mice Exposed to Polystyrene Microspheres
Researchers found that gut microbiota appeared to play a mediating role in the obesity outcomes observed in mice fed manufactured polystyrene microspheres, suggesting that microplastic-induced alterations to the gut microbiome may be a mechanism linking microplastic exposure to metabolic dysfunction and weight gain.
Characterizing the Gut Microbial Metabolic Profile of Mice with the Administration of Berry-Derived Cyanidin-3-Glucoside
This paper is not about microplastics — it characterizes how the berry-derived compound cyanidin-3-glucoside alters gut microbiome composition and metabolic profiles in mice.
Integrated Analysis of the Transcriptome and Microbial Diversity in the Intestine of Miniature Pig Obesity Model
Researchers fed miniature pigs a high-fat, high-carbohydrate diet for 26 weeks and compared their gut health to pigs on a normal diet. The obesity-prone pigs showed increased inflammation, disrupted blood sugar metabolism, and significant declines in beneficial gut bacteria. The study reveals strong connections between diet-induced gut microbial changes and immune-related gene expression in the intestines.
Intermittent fasting protects against food allergy in a murine model via regulating gut microbiota
In a mouse model of food allergy, long-term intermittent fasting attenuated allergic responses by reducing Th2 inflammation, maintaining intestinal barrier integrity, and preventing gut microbiota dysbiosis.
The impact of microplastics on the mice gut microbiome: a meta-analysis
This meta-analysis pools data from multiple mouse studies to assess how ingested microplastics affect gut bacteria. It found that microplastic exposure can alter the balance of the gut microbiome, which is important because gut health is closely tied to immune function, digestion, and overall well-being.
Dysbiosis of gut microbiota in C57BL/6-Lepem1hwl/Korl mice during microplastics-caused hepatic metabolism disruption
Researchers administered polypropylene microplastics orally to obese mice for 9 weeks and found disruption of hepatic lipid, glucose, and amino acid metabolism alongside structural changes in gut microbiota, with microplastic-treated mice showing decreased hepatic lipid accumulation and altered abundance of specific bacterial genera.
Effects of frying on microplastics load in fish and implications on health
Researchers investigated the effects of polyethylene microplastics on gut microbiota composition in mice fed a high-fat diet, finding that microplastic exposure altered microbial diversity and increased gut permeability. Co-exposure with a high-fat diet amplified metabolic disruption.
Composition of the gut microbiota at the genus level following the administration of MP.
Researchers characterized gut microbiota at the genus level in wild-type and leptin-knockout obese mice following microplastic administration, identifying genus-level shifts with significant differences between obese and normal-weight animals that suggest obesity modifies the gut microbiome response to microplastic exposure.
Multi-Omics Analysis of the Gut-Liver Axis Reveals the Mechanism of Liver Injury in Colitis Mice
Researchers used multi-omics analysis to reveal that liver injury in colitis mice is linked to intestinal dysbiosis and altered host-microbiota interactions, with gut bacterial shifts correlating to immune and metabolic changes in the liver.
Gut microbiota and liver metabolomics reveal the potential mechanism of Lactobacillus rhamnosus GG modulating the liver toxicity caused by polystyrene microplastics in mice
Researchers found that the probiotic Lactobacillus rhamnosus GG helped protect mice from liver damage caused by polystyrene microplastic exposure. The probiotic worked by restoring healthy gut bacteria and normalizing liver metabolic pathways disrupted by the microplastics. The study suggests that supporting gut health through beneficial bacteria may help mitigate some of the toxic effects microplastics have on the liver.
Melatonin and probiotics ameliorate nanoplastics-induced hematopoietic injury by modulating the gut microbiota-metabolism
Researchers found that melatonin and probiotics can ameliorate nanoplastic-induced hematopoietic injury in mice by modulating gut microbiota and metabolism, offering potential prevention strategies against plastic particle toxicity to bone marrow stem cells.
Deciphering Gut Microbiome Responses upon Microplastic Exposure via Integrating Metagenomics and Activity-Based Metabolomics
Using advanced metagenomics and metabolomics techniques, researchers studied how polystyrene microplastic exposure affects the gut microbiome in mice. The study found that microplastics disrupted the balance of gut bacteria and altered metabolic pathways related to amino acids and lipids. These findings suggest that microplastic exposure could influence gut health and metabolism, though more research is needed to understand the implications for human health.
In vivo exposure of mixed microplastic particles in mice and its impacts on the murine gut microbiome and metabolome
Researchers exposed mice to a mixture of common microplastic types to investigate effects on the gut microbiome and metabolome. The study found that ingested microplastic particles altered gut microbial composition and disrupted metabolic pathways, suggesting that realistic mixed-microplastic exposure may have broader biological effects than single-polymer studies indicate.
Long-Term Exposure to Polystyrene Microspheres and High-Fat Diet-Induced Obesity in Mice: Evaluating a Role for Microbiota Dysbiosis.
A long-term mouse study examined how chronic exposure to polystyrene microspheres interacts with a high-fat diet to affect obesity-related outcomes, finding that microplastics worsened metabolic disruption and fat accumulation compared to diet alone. The results raise concern that microplastic exposure may be an environmental factor contributing to the global obesity epidemic.
Polystyrene microplastics induce gut microbiota dysbiosis and hepatic lipid metabolism disorder in mice
Researchers fed mice two sizes of polystyrene microplastics for five weeks and observed significant disruption of gut bacteria and changes in liver fat metabolism. The microplastics decreased mucus production in the gut and shifted the balance of key bacterial populations at multiple taxonomic levels. The study suggests that microplastic ingestion can trigger gut microbiota imbalance in mammals, which may in turn affect metabolic health.
Relevance of gut microbiome research in food safety assessment
This review examined how the gut microbiome metabolizes non-nutritious dietary compounds, arguing that gut microbial processing of food contaminants and additives is an underappreciated dimension of food safety assessment.
