The Role of Nuclear Receptor-Binding SET Domain Family Histone Lysine Methyltransferases in Cancer.

ABSTRACT: The nuclear receptor-binding SET Domain (NSD) family of histone H3 lysine 36 methyltransferases is comprised of NSD1, NSD2 (MMSET/WHSC1), and NSD3 (WHSC1L1). These enzymes recognize and catalyze methylation of histone lysine marks to regulate chromatin integrity and gene expression. The growing number of reports demonstrating that alterations or translocations of these genes fundamentally affect cell growth and differentiation leading to developmental defects illustrates the importance of this family. In addition, overexpression, gain of function somatic mutations, and translocations of NSDs are associated with human cancer and can trigger cellular transformation in model systems. Here we review the functions of NSD family members and the accumulating evidence that these proteins play key roles in tumorigenesis. Because epigenetic therapy is an important emerging anticancer strategy, understanding the function of NSD family members may lead to the development of novel therapies.

Project description:BackgroundMembers of the nuclear receptor-binding SET domain (NSD) family of histone H3 lysine 36 methyltransferases comprise NSD1, NSD2 (MMSET/WHSC1), and NSD3 (Wolf-Hirschhorn syndrome candidate 1-like 1, WHSC1L1). While the expression of NSD genes is essential to normal biological processes and cancer, knowledge of their expression levels to prognosticate in cancer remains unclear.MethodsWe analyzed the expression patterns for NSD family genes across multiple cancer types and examined their association with clinical features and patient survival profiles. Next, we explored the association between NSD3 expression and described features of the tumor microenvironment (TME) in PAAD, a severe type of pancreatic cancer. In particular, we correlated promoter methylation levels for NSD3 with patient outcomes in PAAD. Finally, we explored the putative oncogenic roles for NSD3 using a series of experiments with pancreatic cancer cells.ResultsWe report that the expression of NSD family members is correlated with clinical prognosis across multiple types of cancers. Also, we demonstrate that NSD3 variants are most prevalent among NSD genes across cancers we analyzed. Notably, when compared with NSD1 and NSD2, we find that NSD3 is prominently expressed, and its expression is significantly linked with clinical outcome in pancreatic cancer. Furthermore, NSD3 is frequently amplified, exhibits low promoter methylation, and is correlated with immune cell infiltration and enhanced proliferation of pancreatic cancer. Finally, we demonstrate that knockdown of NSD3 alters H3K36me2 methylation, downstream gene expression and EGFR/ERK signaling in pancreatic cancer cells.ConclusionsWe find that expression levels, the presence of genetic variants of NSD family genes, as well as their promoter methylation are correlated with clinical outcomes in cancer, including pancreatic cancer. Our in vitro experiments suggest that NSD3 may be relevant to gene expression regulation and growth factor signaling in pancreatic cancer.
