Project description:Genome-wide expression studies were performed on dermal fibroblasts from Sotos syndrome patients with a confirmed NSD1 abnormality and compared with age-sex matched controls. We used microarrays to detect differentially expressed genes in Sotos syndrome patients and performed a global test with the aim to map NSD1 within a signaling transduction pathway. Dermal fibroblasts were obtained from nine Sotos syndrome patients and nine controls. Since NSD1 is a co-factor of the retinoic acid receptor, cultures were performed both in the presence and absence of retinoic acid.

Project description:Nuclear-receptor-binding SET-domain protein 1 (NSD1), a methyltransferase that catalyzes H3K36me2, is essential for mammalian development and frequently dysregulated in diseases, including Sotos syndrome. Despite impacts of H3K36me2 on H3K27me3 and DNA methylation, a direct role of NSD1 in transcriptional regulation remains largely unknown. Here, we show that NSD1 and H3K36me2 are enriched at cis-regulatory elements, particularly enhancers. NSD1 enhancer association is conferred by a tandem quadruple PHD-PWWP module, which recognizes p300-catalyzed H3K18ac. By combining acute NSD1 depletion with time-resolved epigenomic and nascent transcriptomic analyses, we demonstrate that NSD1 promotes enhancer-dependent gene transcription by facilitating RNA polymerase II pause release. Notably, NSD1 can act as a transcriptional coactivator independent of its catalytic activity. Moreover, NSD1 enables activation of developmental transcriptional programs associated with Sotos syndrome pathophysiology and controls ESC multilineage differentiation. Collectively, we have identified NSD1 as an enhancer-acting transcriptional coactivator that contributes to cell fate transition and Sotos syndrome development.

Project description:Nuclear-receptor-binding SET-domain protein 1 (NSD1), a methyltransferase that catalyzes H3K36me2, is essential for mammalian development and frequently dysregulated in diseases, including a spectrum of cancers and the genetic disorder Sotos syndrome. Despite its function in modulating the chromatin landscape, a direct role of NSD1 in transcriptional regulation remains largely unknown. Here, we show that NSD1 and H3K36me2 are enriched at cis-regulatory elements, particularly enhancers, in a cell type-specific manner. NSD1 enhancer association is conferred by its tandem quadruple PHD-PWWP domain, which is a hotspot for Sotos syndrome missense mutations. By combining acute NSD1 depletion with temporally resolved epigenomic and nascent transcriptomic analysis, we demonstrate that NSD1/H3K36me2 plays a critical role in facilitating enhancer-dependent gene transcription by promoting promoter pause release of RNA polymerase II. Moreover, NSD1 regulates ESC multilineage differentiation through facilitating transcriptional activation of critical developmental programs implicated in Sotos syndrome pathogenesis. Collectively, we have identified NSD1 as a novel enhancer-acting transcriptional coactivator and provided mechanistic insights into its contribution to cell fate transition and association with a human developmental disorder.

Project description:Sotos syndrome (SS) represents an important human model system for the study of epigenetic regulation; it is an overgrowth/intellectual disability syndrome caused by mutations in a histone methyltransferase, NSD1. As layered epigenetic modifications are often interdependent, we propose that pathogenic NSD1 mutations have a genome-wide impact on the most stable epigenetic mark, DNA methylation (DNAm). By interrogating DNAm in SS patients, we identify a genome-wide, highly significant NSD1+/- specific signature that differentiates pathogenic NSD1 mutations from controls, benign NSD1 variants and the clinically overlapping Weaver syndrome. Validation studies of independent cohorts of SS and controls assigned 100% of these samples correctly. This highly specific and sensitive NSD1+/- specific signature encompasses genes that function in cellular morphogenesis and neuronal differentiation, reflecting cardinal features of the SS phenotype. The identification of SS-specific genome-wide DNAm alterations will facilitate both the elucidation of the molecular pathophysiology of SS and the development of improved diagnostic testing. Bisulphite converted DNA from 122 samples were hybridized to the Illumina Infinium 450k Human Methylation Beadchip array.
