The main reason for a relatively low ABL2 could be the control by miRNAs (miR-30a-5p—in LUAD [254], miR-4723—in prostate cancer [255], miR-425-5p—in esophageal squamous cell carcinoma, lung and colon cancer [256], etc.)targeting ABL2 mRNA. The gene discussed is ABL2; the disease is colonic neoplasm.
