The study found that gut microbiome dysbiosis caused abnormal lipid metabolism, and DHA was able to repair the lipid metabolism shifts resulting from gut microbiome dysbiosis. DHA could modulate host-gut microbiome signatures, improve concentrations of SCFAs, regulate fatty acids metabolism, and modify bile acid profiles.
Huge of previous reports recommended that gut microbiome have a crucial role in the human health and its change was profound impact for the metabolic improvements associated with lipids metabolism. In order to explore the relevance of a direct dysbiosis effect of gut microbiome on lipids metabolism shifts and repaired position of DHA, we built the animal model for the study with gut microbiome dysbiosis administrated by i.g. with CRO and intervened by DHA in the present work. Gut microbiome was analyzed by high throughput sequencing and bioinformatics analyses of bacteria. The composition of fatty acids and short chain fatty acids (SCFAs) were determined by gas chromatography. Blood lipids and bile acids were assayed by kit and UPLC-MS/MS, respectively. The expressions of enzymes of long chain fatty acid metabolism were analyzed by qRT-PCR. The results showed that gut microbiome dysbiosis caused lipid metabolism abnormal, and DHA was able to repair the lipids metabolism shifts resulted from gut microbiome dysbiosis. DHA could modulate host-gut microbiome signatures, improve concentrations of SCFAs, regulate fatty acids metabolism but modify bile acid profiles. In conclusion, we considered that DHA repaired lipid metabolism by modulating gut microbiome and regulating fatty acids metabolism pathway.
