Change in metabolic profiles of IgAN rats upon ZWT treatment. (A) PCA plots [positive (A) and negative (B) ion mode] displaying grouped discrimination among the three groups, based on the first two principal components. (B) Loading plots of PLS-DA model [positive (A) and negative (B) ion mode] derived from the potential biomarker metabolites in the serum samples of normal, model, and ZWT groups. (C) Top 10 important discriminatory metabolites upon ZWT treatment, as identified using KEGG pathway enrichment analysis. (D) Schematic overview of bile secretion metabolic pathway changes in IgAN rats upon ZWT treatment. The metabolites are shown in color: red color represents an increase in the levels of metabolite, while green color represents a decrease.
