AKT1 and cancer: Top five KEGG pathways related to specific proteins in NR-EVs were pathways in cancer (red; 15 proteins, p = 1.74 × 10− 11), PI3K/AKT signaling pathway (purple; 12 proteins, p = 8.4 × 10− 8), proteoglycans in cancer (green; ten proteins, p = 1.58 × 10− 7), antigen processing and presentation (yellow; six proteins, p = 4.56 × 10− 6) and bladder cancer (lilac; five proteins, p = 5.34 × 10− 6).
