The miRNA-targeted gene annotation analysis demonstrated that the Hippo signaling pathway (ko04390), cell adhesion molecules (ko04514), the MAPK signaling pathway (ko04010), and the neuroactive ligand-receptor interaction (ko04080) were common annotations in both luminal B BC (Figure 3A) and TNBC (Figure 3B); while the phosphatidylinositol signaling system (ko04070) and the JAK–STAT signaling pathway (ko04630) were TNBC-specific pathways according to KEGG analysis. The gene discussed is SOAT1; the disease is breast cancer.
