Supplementing with DHA-rich microalgae oil improved lipid balance and liver health in a mouse model of metabolic dysfunction. It also positively altered gut bacteria, offering potential for treating fatty liver disease.
Area of Science:
- Biochemistry
- Microbiology
- Metabolomics
Background:
- Metabolically, dysfunctional steatotic liver disease (MSDL) is a common metabolic disorder linked to gut dysbiosis and imbalanced liver lipids.
- Understanding the interplay between diet, gut microbiota, and liver health is crucial for MSDL management.
Purpose of the Study:
- To investigate the effects of DHA-rich microalgae oil supplementation on a high-fat diet-induced mouse model of MSDL.
- To assess the impact on metabolic parameters, gut microbiota composition, microbial function, and hepatic metabolomics.
Main Methods:
- Established a high-fat diet mouse model over 8 weeks.
- Administered oral microalgae oil, probiotics, or a combination daily.
- Analyzed metabolic markers, gut microbiota via 16S rRNA sequencing, microbial pathways, and liver metabolites.
Main Results:
- DHA-rich microalgae oil improved lipid homeostasis, reducing LDL-c and liver triglycerides while increasing HDL-c.
- Observed beneficial shifts in gut microbiota, including increased Lactobacillus and Bifidobacterium.
- Microbiome-metabolome analysis revealed links between microbial changes and hepatic lipid, bile acid, and amino acid metabolism.
Conclusions:
- DHA-rich microalgae oil supplementation shows promise in improving hepatic lipid metabolism and gut microbiota in a mouse model.
- Findings suggest a potential therapeutic role for microalgae oil in managing MSDL-related metabolic disturbances.
