We found 7 exclusive KEGG pathways in the interaction between DE-mRNA and EVOO-miRNA-EVs [melanoma (hsa05218), notch signaling (hsa04330), renal cell carcinoma (hsa05211), endocytosis (hsa04144), chemokine signaling (hsa04062), prostate cancer (hsa05215) and neurotrophin signaling (hsa04722)]. This evidence concerns the gene BDNF and prostate carcinoma.
