CDH1 and neoplasm: Hence, miRNA‐4736 has an oncogenic role, and a step‐by‐step increase in expression levels correlates with disease severity (lowest in healthy individuals, moderate in benign tumors, and highest in sarcoma patients).47 miRNA‐655‐3p regulates E‐cadherin expression and inhibits β‐catenin signal pathway, thereby functioning as a tumor suppressor in hepatocellular carcinoma.48 It also halts tumor invasion and metastatic dissemination in various cancer types.49
