Fig. 4From: Tauroursodeoxycholic acid (TUDCA) improves intestinal barrier function associated with TGR5-MLCK pathway and the alteration of serum metabolites and gut bacteria in weaned pigletsTUDCA supplementation changed serum metabolic profiles of weaned piglets (n = 6). A The scores plots of serum metabolites of CON group and TUDCA group were obtained by orthogonal partial least squares discriminant analysis (OPLS-DA). B The main up-regulated (red-marked) and down-regulated (green-marked) serum differential metabolites. C Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment of serum differential metabolites. The color of the point and the size of the spot represented P-value and the number of different metabolites enriched, respectivelyBack to article page
