PRL and cancer: For miR‐101‐5p, 90 KEGG pathways were enriched, and the top pathways were (a) pathways in cancer (hsa05200: P = 7.08 × 10−16), (b) the forkhead box O (FoxO) signaling pathway (hsa04068: P = 5.59 × 10−14), (c) hepatitis B (hsa05161: P = 2.82 × 10−12), (d) the phosphoinositide‐3‐kinase (PI3K)–Akt signaling pathway (hsa04151: P = 7.91 × 10−11) and (e) the prolactin signaling pathway (hsa04917: P = 2.43 × 10−8).
