ChIP-seq of CSF-1R in THP-1 cell lines deleted for EGR1 gene by CRISPR-Cas9 and ChIP-seq of CSF-1R in 2 CMML patients

Project description:CSF-1R is recruited on EGR1 motifs in monocytes where it colocalizes with EGR1. To address if EGR1 required for CSF-1R recruitment on chromatin, THP-1 monocytic cell line has been deleted for EGR1 by CRISPR-Cas9 approach. 3 clones were generated by single cell cloning and CSF-1R localization on chromatin was compared to two unmodified THP-1 clones by ChIP-sequencing. Since the read number was strongly decreased in the EGR1-deleted clones, the three clones were pooled for the comparison with wild-type clones.

The Transcriptome Of Cmml Monocytes Is Highly Inflammatory And Reflects Leukemia-Specific And Age-Related Alterations

Project description:Chronic myelomonocytic leukemia (CMML) is an aggressive myeloid neoplasm of older individuals characterized by persistent monocytosis. Somatic mutations in CMML are heterogeneous and only partially explain the variability in clinical outcomes. Recent data suggest that cardiovascular morbidity is increased in CMML and contributes to reduced survival. Clonal hematopoiesis of indeterminate potential (CHIP), the presence of mutated blood cells in hematologically normal individuals, is a precursor of age-related myeloid neoplasms and associated with increased cardiovascular risk. To isolate CMML-specific alterations from those related to aging, we performed RNA sequencing and DNA methylation profiling on purified monocytes from CMML patients and from age-matched (old) and young healthy controls. We found that the transcriptional signature of CMML monocytes is highly pro-inflammatory, with upregulation of multiple inflammatory pathways, including tumor necrosis factor, IL-6 and IL-17 signaling, while age per se does not significantly contribute to this pattern. We observed no consistent correlations between aberrant gene expression and CpG island methylation, suggesting that pro-inflammatory signaling in CMML monocytes is governed by multiple and complex regulatory mechanisms. We propose that pro-inflammatory monocytes may contribute to cardiovascular morbidity in CMML patients, and promote progression by selection of mutated cell clones. Our data raise questions whether asymptomatic CMML patients may benefit from monocyte-depleting or anti-inflammatory therapies.

Macrophage migration inhibitory factor is overproduced through EGR1 in TET2low resting monocytes

Project description:Somatic mutation in TET2 gene is one of the most common clonal genetic events detected in age-related clonal hematopoiesis as well as in chronic myelomonocytic leukemia (CMML). In addition to being a pre-malignant state, TET2 mutated clones are associated with an increased risk of death from cardiovascular disease, which could involve cytokine/chemokine overproduction by monocytic cells. Here, we show in mice and in human cells that, in the absence of any inflammatory challenge, TET2 down-regulation promotes the production of MIF (macrophage migration inhibitory factor), a pivotal mediator of atherosclerotic lesion formation. In healthy monocytes, TET2 is recruited to MIF promoter and interacts with the transcription factor EGR1 and histone deacetylases. Disruption of these interactions as a consequence of TET2-decreased expression favors EGR1-driven transcription of MIF gene and its secretion. MIF favors monocytic differentiation of myeloid progenitors. These results designate MIF as a chronically overproduced chemokine and a potential therapeutic target in patients with clonal TET2 down-regulation in myeloid cells.
