SETD1A regulates transcriptional pause release of heme biosynthesis genes in leukemia [RNA-seq]

ABSTRACT: Histone methyltransferase SETD1A is critical for acute myeloid leukemia (AML) cell survival, but the molecular mechanism driving SETD1A gene regulation remains elusive. To delineate the role of SETD1A, we utilize a protein degrader technology to induce rapid SETD1A degradation in AML cell lines. SETD1A degradation results in immediate downregulation of transcripts associated with DNA repair and heme biosynthesis pathways. CRISPR-based functional analyses and metabolomics revealed an essential role of SETD1A to maintain mitochondrial respiration in AML cells. These SETD1A targets are enriched in head-to-head (H2H) genes. SETD1A degradation disturbs a non-enzymatic SETD1A domain-dependent cyclin K function, increases the mono-Ser5P RNA polymerase II (RNAP2) at TSS, and induces the promoter-proximal pausing of RNAP2 in a strand-specific manner. This study reveals a non-enzymatic role for SETD1A in transcriptional pause release and provides insight into the mechanism of RNAP2 pausing and its function in cancer.

A non-catalytic function of SETD1A regulates Cyclin K and the DNA damage response [RNA-seq]

Project description:MLL/SET methyltransferases catalyze methylation of histone 3 lysine 4 and play critical roles in development and cancer. We assessed MLL/SET proteins and found that SETD1A is required for survival of acute myeloid leukemia (AML) cells. Mutagenesis studies and CRISPR-Cas9 domain screening, showed the enzymatic SET domain is not necessary for AML cell survival but that a newly identified region, termed the FLOS (Functional Location on SETD1A) domain, is indispensable. FLOS disruption suppresses DNA damage response genes and induces p53-dependent apoptosis. The FLOS domain acts as a Cyclin K-binding site that is required for chromosomal recruitment of Cyclin K, and for DNA repair-associated gene expression in S phase. These data identify a connection between the chromatin regulator SETD1A and the DNA damage response that is independent of histone methylation, and suggests that targeting SETD1A and Cyclin K complexes may represent a therapeutic opportunity for AML and potentially other cancers.

Recapitulation and reversal of schizophrenia-related phenotypes in Setd1a-deficient mice

Project description:SETD1A, a histone methyltransferase, is a key schizophrenia susceptibility gene. Mutant mice carrying a heterozygous loss-of-function mutation of the orthologous gene exhibit alterations in axonal branching and cortical synaptic dynamics, accompanied by specific deficits in working memory that recapitulates SCZ-related alterations. We show that Setd1a targets mostly enhancers and reveal a striking overlap between Setd1a and Mef2 chromatin targets. Setd1a targets are highly expressed in pyramidal neurons and enriched for genes with postnatally-biased expression involved in synaptic structure and function. Notably, evolutionary conserved Setd1a binding sites and target genes are strongly associated with neuropsychiatric genetic risk burden. Reinstating Setd1a expression in adulthood rescues working memory deficits. We identify LSD1 as a major demethylase counteracting the effects of Setd1a methyl transferase activity and show that LSD1 antagonism in adult Setd1a-deficient mice results in a full rescue of the behavioral abnormalities and axonal branching deficits. Our findings advance our understanding of how SETD1A mutations predispose to SCZ and point to therapeutic interventions.

BOD1L mediates chromatin binding and non-canonical function of H3K4 methyltransferase SETD1A (RNA-seq)

Project description:The H3K4 methyltransferase SETD1A plays an essential role in both development and cancer. However, essential components involved in SETD1A chromatin binding remain unclear. Here, we discovered that BOD1L exhibits the highest correlated co-dependency with SETD1A in human cancer cell lines. BOD1L knockout reduces leukemia cells in vitro and in vivo, and mimics the transcriptional profiles observed in SETD1A knockout cells. The loss of BOD1L immediately reduced SETD1A distribution at transcriptional start sites (TSS) and induces transcriptional elongation defect along with the increasing of RNA polymerase II at TSS, but did not cause the reduction of H3K4me3. The Shg1 domain of BOD1L has a DNA binding ability, and recruit SETD1A to chromatin through the association with SETD1A FLOS domain. In addition, the BOD1L-SETD1A complex associates with transcriptional regulators, including E2Fs. These results reveal that BOD1L mediates chromatin and SETD1A, and regulates the non-canonical function of SETD1A in transcription.

Epigenetic modification of GR enhancers by SETD1A/COMPASS complex in murine macrophages

Project description:Nuclear interaction studies by ChIP coupled with mass spectrometry identified the COMPASS/SETD1A complex as interaction partner of the glucocorticoid receptor (GR) in murine bone marrow-derived macrophages (BMDMs). Here, we profiled the occupancy of SETD1A and CXXC1, two subunits of the COMPASS/SETD1A complex in murine macrophages after LPS and Dex+LPS stimulation. We show, that GR recuits SETD1A and CXXC1 to GR enhancer and that SETD1A recruitment does correlate with changes in H3K4methylation at some of those enhancers.
