Transcription factor-driven coordination of cell cycle exit and lineage-specification in vivo during granulocytic differentiation : In memoriam Professor Niels Borregaard. Nat Commun 2022; 13:3595. [PMID: 35739121 PMCID: PMC9225994 DOI: 10.1038/s41467-022-31332-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Accepted: 06/14/2022] [Indexed: 12/14/2022] Open
Abstract
Differentiation of multipotent stem cells into mature cells is fundamental for development and homeostasis of mammalian tissues, and requires the coordinated induction of lineage-specific transcriptional programs and cell cycle withdrawal. To understand the underlying regulatory mechanisms of this fundamental process, we investigated how the tissue-specific transcription factors, CEBPA and CEBPE, coordinate cell cycle exit and lineage-specification in vivo during granulocytic differentiation. We demonstrate that CEBPA promotes lineage-specification by launching an enhancer-primed differentiation program and direct activation of CEBPE expression. Subsequently, CEBPE confers promoter-driven cell cycle exit by sequential repression of MYC target gene expression at the G1/S transition and E2F-meditated G2/M gene expression, as well as by the up-regulation of Cdk1/2/4 inhibitors. Following cell cycle exit, CEBPE unleashes the CEBPA-primed differentiation program to generate mature granulocytes. These findings highlight how tissue-specific transcription factors coordinate cell cycle exit with differentiation through the use of distinct gene regulatory elements. Here the authors show that differentiation of haematopoietic stem cells into mature blood cells is primed by cell type-specific transcription factors at the enhancer level during early differentiation, before they confere promoter-driven growth arrest, and activate post-mitotic terminal differentiation.

Front Pediatr 2020; 8:117. [PMID: 32391290 PMCID: PMC7188777 DOI: 10.3389/fped.2020.00117] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Accepted: 03/05/2020] [Indexed: 11/29/2022] Open
Abstract
Severe invasive infections such as brain abscess in a child should prompt an immune evaluation. Specific granule deficiency (SGD) is a rare morphologic neutrophil granular defect characterized by reduced granules within neutrophils, absence of granule proteins, and bilobed nuclei. Patients are susceptible to invasive bacterial infections and Candida infections. Mutations in CCAT/enhancer binding protein epsilon (C/EBP-ε) are the most commonly described cause of SGD. The dihydrorhodamine assay is a quantitative and qualitative functional test that determines the oxidative burst and killing potential of neutrophils. Herein, we describe two brothers with specific granule deficiency. The index patient had a history of cellulitis twice in the first year of life and then presented at 13 months age with fever, leukocytosis, and right sided weakness. A large space occupying brain abscess was diagnosed. He underwent surgical drainage and cultures yielded Staphylococcus aureus. This infection prompted his diagnosis. His older brother had also been healthy but too had had several episodes of cellulitis. His brother too was diagnosed with SGD when family genetic screening was performed. Evaluation of the index patient included a peripheral smear that showed absent neutrophil granule presence. Forward and side scatter of whole blood via flow cytometry revealed a loss of granularity of neutrophils. A DHR was performed to rule out functional killing defects. After stimulation with PMA, neutrophils from the index patient displayed three distinct patterns, two with abnormal oxidase production, and two with reduced function. Both patients were ultimately diagnosed with SGD and remain on lifelong anti-bacterial prophylaxis. Diagnosis of SGD relies on establishing reduced or absent granularity within neutrophils. Lifelong anti-bacterial and anti-fungal prophylaxis is indicated. Hematopoietic cell transplantation has also been curative.

Chromatin-remodeling factor SMARCD2 regulates transcriptional networks controlling differentiation of neutrophil granulocytes. Nat Genet 2017; 49:742-752.

Abstract
We identify SMARCD2 (SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily D, member 2), also known as BAF60b (BRG1/Brahma-associated factor 60b), as a critical regulator of myeloid differentiation in humans, mice, and zebrafish. Studying patients from three unrelated pedigrees characterized by neutropenia, specific granule deficiency, myelodysplasia with excess of blast cells, and various developmental aberrations, we identified three homozygous loss-of-function mutations in SMARCD2. Using mice and zebrafish as model systems, we showed that SMARCD2 controls early steps in the differentiation of myeloid-erythroid progenitor cells. In vitro, SMARCD2 interacts with the transcription factor CEBPɛ and controls expression of neutrophil proteins stored in specific granules. Defective expression of SMARCD2 leads to transcriptional and chromatin changes in acute myeloid leukemia (AML) human promyelocytic cells. In summary, SMARCD2 is a key factor controlling myelopoiesis and is a potential tumor suppressor in leukemia.
