Identification and characterization of mutations in ZBTB33 in clonal hematopoiesis and myelodysplastic syndromes

ABSTRACT: Beauchamp EM, Leventhal M, Bernard E, Hoppe ER, Todisco G, Creignou M, Galli A, Castellano CA, McConkey M, Tarun A, Wong W, Schenone M, Stanclift C, Tanenbaum B, Malolepsza E, Nilsson B, Bick AG, Weinstock JS, Miller M, Niroula A, Dunford A, Taylor-Weiner A, Wood T, Barbera A, Anand S, Psaty BM, Desai P, Cho MH, Johnson AD, Loos R, NHLBI Trans-Omics for Precision Medicine (TOPMed) Consortium, DMacArthur DG, Lek M, Exome Aggregation Consortium, Neuberg DS, Lage K, Carr SA, Hellstrom-Lindberg E, Malcovati L, Papaemmanuil E, Stewart C, Getz G, Bradley RK, Jaiswal S, Ebert BL. 2021. Clonal hematopoiesis results from somatic mutations in cancer driver genes in hematopoietic stem cells. We sought to identify novel drivers of clonal expansion using an unbiased analysis of sequencing data from 84,683 persons and identified common mutations in the 5-methylcytosine reader, ZBTB33, as well as in YLPM1, SRCAP, and ZNF318. We also identified these mutations at low frequency in myelodysplastic syndrome patients. Zbtb33 edited mouse hematopoietic stem and progenitor cells exhibited a competitive advantage in vivo and increased genome-wide intron retention. ZBTB33 mutations are potentially linked to DNA methylation and RNA splicing, the two most commonly mutated pathways in clonal hematopoiesis and MDS.

Sequential CRISPR gene editing in human iPSCs charts the clonal evolution of leukemia

Project description:Human cancers arise through an evolutionary process whereby cells acquire somatic mutations that drive them to outgrow normal cells and create successive clonal populations. “Bottom-up” human cancer evolution models could help illuminate this process, but their creation has faced significant challenges. Here we combined human induced pluripotent stem cell (iPSC) and CRISPR/Cas9 technologies to develop a model of the clonal evolution of acute myeloid leukemia (AML). Through the sequential introduction of 3 disease-causing mutations (ASXL1 C-terminus truncation, SRSF2P95L and NRASG12D), we obtained single, double and triple mutant iPSC lines that, upon hematopoietic differentiation, exhibit progressive dysplasia with increasing number of mutations, capturing distinct premalignant stages, including clonal hematopoiesis, myelodysplastic syndrome, and culminating in a transplantable leukemia. iPSC-derived clonal hematopoietic stem/progenitor cells recapitulate transcriptional and chromatin accessibility signatures of normal and malignant hematopoiesis found in primary human cells. By mapping dynamic changes in transcriptomes and chromatin landscapes, we characterize transcriptional programs driving specific stage transitions and identify vulnerabilities for early therapeutic targeting. Such synthetic “de novo oncogenesis” models can empower the investigation of multiple facets of the malignant transformation of human cells.

Resistance to inflammation underlies enhanced fitness in clonal hematopoiesis [II]

Project description:Clonal hematopoiesis (CH) results from enhanced fitness of a mutant hematopoietic stem and progenitor cell (HSPC), but how such clones expand is unclear. Here, we developed a technique that combines mosaic mutagenesis with color labeling of HSPCs to study how acquired mutations affect clonal fitness in a native environment. Mutations in CH-associated genes, like asxl1, promoted clonal dominance. Single-cell transcriptional analysis revealed that mutations stimulated expression of proinflammatory genes in mature myeloid cells and anti-inflammatory genes in progenitor cells of the mutant clone. Biallelic loss of one such immunomodulator, nr4a1, abrogated the ability of asxl1-mutant clones to establish clonal dominance. These results support a model where clonal fitness of mutant clones is driven by enhanced resistance to inflammatory signals from their mutant mature cell progeny.

Distinct TNF Receptors Dictate Stem Cell Fitness Versus Lineage Output in Clonal Hematopoiesis of Aging

Project description:Clonal hematopoiesis of aging results from enhanced fitness of mutant hematopoietic stem cells (HSCs) and associates with both favorable and unfavorable health outcomes related to lineage cell types produced by mutant HSCs. The extent to which lineage output can be controlled in clonal hematopoiesis is unknown. Using a mouse model of DNMT3AR882/+ clonal hematopoiesis (Dnmt3aR878H/+), we find that aging-induced TNFα signaling drives selective advantage of mutant HSCs concomitant with B lymphoid lineage production. Genetic loss of TNFα receptor TNFR1 impaired mutant HSC fitness while loss of TNFR2 abrogated lymphoid production and resulted in unrestrained myeloid cell production from mutant HSCs. These results support a model where clone size and lineage output can be independently targeted to harness potential beneficial aspects of clonal hematopoiesis.

Tet2-mediated clonal hematopoiesis in nonconditioned mice accelerates age-associated cardiac dysfunction

Project description:Clonal hematopoiesis of indeterminate potential is prevalent in elderly individuals and associated with increased risks of all-cause mortality and cardiovascular disease. However, mouse models to study the dynamics of clonal hematopoiesis and its consequences on the cardiovascular system under homeostatic conditions are lacking. We used a model of clonal hematopoiesis using adoptive transfer of unfractionated ten-eleven translocation 2-mutant (Tet2-mutant) bone marrow cells into nonirradiated mice. Consistent with age-related clonal hematopoiesis observed in humans, these mice displayed a progressive expansion of Tet2-deficient cells in multiple hematopoietic stem and progenitor cell fractions and blood cell lineages. The expansion of the Tet2-mutant fraction was also observed in bone marrow-derived CCR+ myeloid cell populations within the heart, but there was a negligible impact on the yolk sac-derived CCR2- cardiac resident macrophage population. Transcriptome profiling revealed an enhanced inflammatory signature in the donor-derived macrophages isolated from the heart. Mice receiving Tet2-deficient bone marrow cells spontaneously developed age-related cardiac dysfunction characterized by greater hypertrophy and fibrosis. Altogether, we show that Tet2- mediated hematopoiesis contributes to cardiac dysfunction in a nonconditioned setting that faithfully models the human clonal hematopoiesis in unperturbed bone marrow. Our data support clinical findings that clonal hematopoiesis per se may contribute to diminished health span.

Clonal analysis of lineage fate in unperturbed hematopoiesis

Project description:The classical tenet of hematopoiesis posits well-accepted lineage trees that arise from progressively restricted oligopotent and unipotent progenitor populations. However, because fate in hematopoiesis has mostly been studied in the context of transplantation, it is unclear whether these lineage branches and such proposed oligopotent progenitors exist in an unperturbed hematopoietic system. Here, we utilize endogenous transposon tagging to trace the fate of thousands of progenitors and stem cells over time to re-evaluate these dogmas. Our results describe a novel clonal roadmap where the megakaryocyte lineage arises independently of lymphoid and myeloid/erythroid fates. Our data also demonstrate that true oligopotency is largely restricted to the multipotent progenitor (MPP) compartment. Analysis of thousands of stem cell and progenitor transcriptomes demonstrates that lineage determination starts at the MPP stage and identifies a functional hierarchy within this population that drives hematopoiesis. Finally, our results demonstrate that long-term hematopoietic stem cells behave physiologically as megakaryocyte lineage progenitors. Our data provide evidence for a substantially revised hematopoietic roadmap, and highlights unique properties of MPPs and HSCs in situ.

Mutant ASXL1 induces age-related expansion of phenotypic hematopoietic stem cells through activation of Akt/mTOR pathway

Project description:Somatic mutations of ASXL1 are frequently detected in age-related clonal hematopoiesis (CH). However, how ASXL1 mutations drive CH remains elusive. Using knockin (KI) mice expressing a C-terminally truncated form of ASXL1-mutant (ASXL1-MT), we examined the influence of ASXL1-MT on physiological aging in hematopoietic stem cells (HSCs). HSCs expressing ASXL1-MT display competitive disadvantage after transplantation. Nevertheless, in genetic mosaic mouse model, they acquire clonal advantage during aging, recapitulating CH in humans. Mechanistically, ASXL1-MT cooperates with BAP1 to deubiquitinate and activate AKT. Overactive Akt/mTOR signaling induced by ASXL1-MT results in aberrant proliferation and dysfunction of HSCs associated with age-related accumulation of DNA damage. Treatment with an mTOR inhibitor rapamycin ameliorates aberrant expansion of the HSC compartment as well as dysregulated hematopoiesis in aged ASXL1-MT KI mice. Our findings suggest that ASXL1-MT provokes dysfunction of HSCs, whereas it confers clonal advantage on HSCs over time, leading to the development of CH.

Identification of cell-intrinsic effects of clonal hematopoiesis in heart failure

Project description:Clonal hematopoiesis of indeterminate potential (CHIP) is caused by somatic mutations in hematopoietic stem cells and is associated with worse prognosis in heart failure patients. Patients harboring CHIP mutations show enhanced inflammation. However, whether these signatures are derived from the relatively low number of cells harboring mutations or are indicators of a systemic pro-inflammatory activation that is associated with CHIP is unclear. In this study, we assessed the cell-intrinsic effects of CHIP mutant-carrying cells in patients with heart failure. Using an improved protocol to detect mutant cells on a single cell level (MutDetect-Seq), we show that DNMT3A mutant monocytes exhibit altered gene expression profiles associated with inflammation and phagolysosome function. Gene expression was also significantly altered in DNMT3A mutant CD4+ T cells and NK cells, but not CD8 T cells. DNMT3A silenced CD4+ T cells and NK cells showed increased effector functions. Moreover, increased paracrine signaling pathways are predicted and validated between mutated and wild monocytes and T cells, which amplify inflammatory circuits. Taken together, these data provide novel insights into how CHIP might promote worse prognosis in heart failure patients.

Clonal barcoding of endogenous adult hematopoietic stem cells reveals a spectrum of lineage contributions

Project description:The hierarchical model of hematopoiesis posits that self-renewing, multipotent hematopoietic stem cells (HSCs) give rise to all blood cell lineages. While this model accounts for hematopoiesis in transplant settings, its applicability to steady-state hematopoiesis remains to be clarified. Here we used inducible clonal DNA barcoding of endogenous adult HSCs to trace their contribution to major hematopoietic cell lineages in unmanipulated animals. Whereas the majority of barcodes were unique to a single lineage, we also observed frequent barcode sharing between multiple lineages, specifically between lymphocytes and myeloid cells. These results suggest a spectrum of multipotent and unipotent HSCs that collectively drive continuous hematopoiesis in the adult, and highlight a close relationship of myeloid and lymphoid development.
