Nevertheless, the histone lysine demethylase 3A (KDM3A) is a histone demethylase in the JmjC domain‐containing protein family and has been associated with the development of tumours due to its ability to enhance gene transcription by demethylating H3K9me1 and H3K9Me2.19, 20, 21. Here, KDM3A is linked to neoplasm.
