Figure 2. RNA-seq analysis of the colorectal of ApcMin/+ mice ingested different concentration of Neu5Gc. (A) t-SNE plots of relative gene expression in the colorectal; (B) Volcano plot for DEGs; (C) Top 10 GO terms of the up-DEGs; (D) Top 10 enriched pathways of the up-DEGs; (E) Top 10GO terms; (F) Top 10 enriched pathways.

Figure 3. PPI analysis of DEGs. DEGs between Treatment and Control groups were investigated using String. The interaction between each protein pair is represented by a line, and the size of the circle is proportional to the degree of interaction. Proteins that are closer to the concentric circles have higher interactions with other proteins.
