Fig. 4: Differential gene expression in Caco-2 cells displayed via a PCA scatter score plot and Venn diagram.

Circles of different colors in the Venn diagram represent different gene sets, and the numerical values represent the number of genes/transcripts that are shared and unique between different gene sets. A Volcano plot of differential metabolites across treatment groups; B PCA score scatter plot for simultaneous comparison of four sample groups; C Quantitative Venn diagram of differential metabolite counts among comparison groups.
