Overview of Gene Research
NSD2, a member of the Nuclear SET Domain (NSD) family, is a histone methyltransferase responsible for dimethylating histone 3 at lysine 36 (H3K36me2). This epigenetic mark is involved in maintaining chromatin integrity and regulating genes related to cell division, apoptosis, DNA repair, and epithelial-mesenchymal transition (EMT) [3,4].
In lung adenocarcinoma (LUAD), the in vivo expression of a hyperactive NSD2 variant (NSD2E1099K) accelerates tumor progression, while NSD2 loss via a CRISPRi-based system strongly attenuates tumor growth. Also, NSD2 knockdown blocks the neoplastic growth of patient-derived xenografts (PDXs) from primary LUAD. Combining NSD2 depletion with MEK1/2 inhibition causes nearly complete regression of LUAD tumors, identifying NSD2 as a therapeutic target [1]. In colon cancer, NSD2 overexpression enhances tumor metastasis by activating Rac1 signaling through methylating Tiam1 at K724 [2]. In neuroendocrine prostate cancer (CRPC-NE), NSD2 maintains lineage plasticity and castration-resistance. Nuclease technology targeting of NSD2 or expression of a dominant-negative oncohistone H3.3K36M mutant can reverse these phenotypes and restore responsiveness to the AR inhibitor enzalutamide [5].
In summary, NSD2 is crucial in the pathogenesis and progression of multiple cancers, including LUAD, colon cancer, and CRPC-NE. The use of gene knockout or knockdown models in these studies has revealed its key role in promoting tumorigenesis and metastasis, highlighting its potential as a therapeutic target in these disease areas.
