Metaproteomics and metabonomics reveal the metabolic dysfunction of gut microbiota in the Tibetan Minipigs with atherosclerosis

Atherosclerosis is fundamental in the development of cardiovascular disease. The unhealthy dietary habits, high fat and cholesterol intake could change the composition of gut microbes and metabolites which play a critical role in the development of atherosclerosis. To characterize the functionality of intestinal microbiome in the AS, we performed an analysis of microbiota proteins by a metaproteomics technique in 6 control samples and 6 feces samples. Using data dependent acquisition (DDA), a total of 8467 peptides with taxonomy annotation were identified and which were correspond to 3851 protein groups.
