A previous study published by Parrish and colleagues uncovered that KDM3A is a miRNA‐22‐3p‐regulated tumour promoter in Ewing sarcoma.42 Here, our data not only demonstrated a negative correlation between miRNA‐22‐3p and KDM3A in MI, but the subsequent luciferase reporter assay also confirmed that miRNA‐22‐3p could directly combine with KDM3A mRNA. Here, KDM3A is linked to neoplasm.
