SOAT1 and cancer: The candidates for differentially expressed proteins in milk sEV made a strong cluster of networking in PPI (Fig. 5A) relating to several KEGG pathways including pathways in cancer, cytokine-cytokine receptor interaction, JAK-STAT signalling pathways, proteoglycans in cancer, focal adhesion, and so on (top 10 KEGG pathways were shown in Fig. 5B).
