Single-Cell multi-omics reveals disrupted gene regulatory landscape and cell differentiation by Wilms tumor-associated ENL mutation in the developing kidney (snATAC-Seq)

ABSTRACT: ENL is an epigenetic acetylation reader and represents the most frequently mutated epigenetic regulator in Wilms tumor. In this study, we established an in vivo mouse model with the ENL hotspot mutation Enl-T1. We performed single-nuclei ATAC sequencing (snATAC-seq) analysis for the Enl-WT and T1 embryonic kidney to study the open chromatin dynamics and gene regulatory mechanism underlying the kidney developing defeat induced by the Enl mutation.

Condensate-promoting ENL mutation induces tumorigenesis via chromatin remodeling [RNA-seq]

Project description:Gain-of-function mutations in the chromatin ‘reader’ ENL, identified in AML and Wilms tumor, have been shown to induce aberrant formation of transcriptional condensates in cellular systems. However, the precise role of these mutations and their condensate forming property in tumorigenesis remains unclear. By creating a conditional knock-in mouse model for the most prevalent ENL mutation, we establish ENL mutant as a bona fide oncogenic driver of acute myeloid leukemia in vivo. Heterozygous expression of ENL mutant perturbs the normal hematopoietic hierarchy and results in the aberrant expansion of myeloid progenitors with increased self-renewal property. Furthermore, the ENL mutant remodels histone modifications to alter differentiation processes and drive oncogenic gene expression during hematopoietic development. Importantly, targeted point mutagenesis to disrupt the condensate formation property completely abolishes ENL mutant’s oncogenic function in hematopoietic stem and progenitor cells (HSPCs). Lastly, short-term treatment with a small molecule inhibitor that blocks the acetyl-binding activity of ENL mutant reverts its impact on chromatin and significantly delays leukemia development in mice. Our studies reveal the crucial biological function of mutation-induced transcriptional condensates in chromatin regulation and cancer in vivo and provide proof-of-concept for targeting of pathogenic condensates as a promising therapy for certain cancers.

Transcriptomic profiling of MLL-ENL and delta YEATS mutant

Project description:To investigate the contribution of ENL YEATS domain and downstream sequences in MLL-ENL leukemogenesis program, we generated MLL-ENL and MLL-ENL ∆YEATS (ENL aa372-559) cell lines by retrovirally introducing these constructs into lineage negative hematopoietic stem and progenitor cells (HSPCs).

ENL reads histone β-hydroxybutyrylation to modulate gene transcription (RNA-Seq)

Project description:Histone modifications are typically recognized by chromatin-binding protein modules (referred to as “readers”) to mediate fundamental processes such as transcription. Lysine β-hydroxybutyrylation (Kbhb) is a new type of histone mark that couples metabolism to gene expression. However, the readers that prefer histone Kbhb remain elusive. This knowledge gap must be filled in order to reveal the molecular mechanism of this epigenetic regulation. Herein, we developed a chemical proteomic approach, relying upon multivalent photoaffinity probes to capture binders of the mark and identified ENL as a novel target of H3K9bhb. Biochemical studies and CUT&Tag analysis further suggested that ENL favorably binds to H3K9bhb, and co-localizes with it on promoter regions to modulate gene expression. Notably, disrupting the interaction between H3K9bhb and ENL via structure-based mutation leads to the suppressed expression of the gene like MYC that drives cell proliferation.

Runx1 deficiency effect on MLL-ENL cells

Project description:To identify the target genes of Runx1 in MLL fusion leukemia, we performed microarray analysis using control and Runx1-deficient MLL-ENL leukemia cells. Runx1 intact and excised bone marrow cells were transduced with MLL-ENL and transplanted into congenic mice. Leukemic cells were harvested from moribund mice, and gene expression was compared using 3 independent leukemia cells for each genotype.

Chemical inhibition of ENL/AF9 YEATS domains in acute leukemia [RNA-Seq]

Project description:Transcriptional co-regulators, which mediate chromatin-dependent transcriptional signaling, represent tractable targets to modulate tumorigenic gene expression programs with small molecules. Genetic loss-of-function studies have recently implicated the transcriptional co-activator, ENL, as a selective requirement for the survival of acute leukemia – particularly those driven by multiple lineage leukemia (MLL)-fusion oncogenes. The YEATS domain of ENL, which binds to chromatin by interacting with acyl-lysine side chains, is critical for its pathogenic function in acute leukemiaand highlighted an essential role for its chromatin reader YEATS domain. Motivated by these recent discoveries, we executed a screen of nearly 300,000 small molecules to identify chromatin-competitiveand identified an amido-imidazopyridine inhibitors of the ENL YEATS domain (IC50 = 7 µM). Leveraging a SuFEx-based high-throughput approach to Optimizing an amido-imidazopyridine scaffold with highly parallelized, SuFEx-based medicinal chemistry optimization, we discovered SR-0813 (IC50 = 25 nM), a potent and selective ENL/AF9 YEATS domain inhibitor that exclusively inhibits the growth of ENL-dependent leukemia cell lines. Armed with this tool and a first-in-class ENL PROTAC, SR-1114, we detailed the response of AML cells to pharmacological ENL disruption for the first time. Most notably, displacement of In AML cells, SR-0813 evicts ENL from chromatin, by SR-0813 preferentially suppresseselicited a strikingly selective suppression of ENL target genes, including HOXA9/10, MYB, MYC and a number of other leukemia proto-oncogenes. Our study reproduces a number of key observations previously made by CRISPR/Cas9 loss of function and dTAG-mediated degradation, and therefore, both reinforces ENL as an emerging leukemia target and validates SR-0813 as a high-quality chemical probe.
