Opa‐interacting protein 5‐antisense transcript 1 (OIP5‐AS1), an evolutionarily conserved LncRNA first discovered in zebrafish,17 plays important roles in various physiological processes, including carcinogenesis and cancer progression,18 myocardial ischemia reperfusion injury,19 diabetic nephropathy,20 and chronic obstructive pulmonary disease.21 Here, OIP5 is linked to cancer.
