Role of NSD1 as potential therapeutic target in tumor

Abstract

Nuclear receptor binding SET Domain Protein 1 (NSD1) is a bifunctional transcriptional regulatory protein that encodes histone methyltransferase. Mono- and di-methylation of H3K36 by NSD1 is mainly primarily involved in the regulation of gene expression, DNA repair, alternative splicing, and other important biological processes. Many types of cancers, including acute myelogenous leukemia (AML), liver cancer, lung cancer, endometrial carcinoma, colorectal cancer, and pancreatic cancer, are associated with NSD1 fusion, missense mutation, nonsense mutation, silent mutation, deletion, and insertion of frameshift, and deletion in a frame. Therefore, targeting NSD1 may be a potential strategy for tumor therapy. An in-depth study of the structure and biological activities of NSD1 sets the groundwork for improving tumor therapy and creating NSD1 inhibitors. This article emphasizes the role of NSD1 in tumorigenesis and the development of NSD1 targeted small-molecule inhibitors.
