T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive proliferation of T-lymphocytes usually associated with oncogenic activation of NOTCH1 signaling. Using a bone marrow transplantation approach, we have modeled murine CD4+ CD8+ T-ALL by overexpressing DNMT3A R882H in Tet2-/- multipotent pro...
We aim at understanding how ionizing radiations (IR) increase the risk of developing myeloid leukemia. We recently showed that IR leads to the derepression of retroelements. Retroelements are major contributors of gene regulatory networks. However, the impact of retroelements derepression on the HSC...
Monocytes were isolated from healthy donors PBMC and sorted for classical and non-classical monocyte subsets. RNA-seq was performed on unstimulated monocytes.
We aim at understanding how ionizing radiations (IR) increase the risk of developing myeloid leukemia. We recently showed that IR leads to the derepression of retroelements. We demonstrated that retroelements expression in aged HSCs is regulated by the heterochromatin repressive histone mark H3K9me3...

Analysis of the RNA-seq data performed in IR vs NIR hematopoietic stem cells show the loss of the TNF_via_NFKB signature. We showed that the loss of this signature could be associated with hematopoietic stem cell gene deregulation. To validate this association, we tested if TNFa treatment before irr...
Analysis of the RNA-seq data performed in IR vs NIR hematopoietic stem cells show the loss of the TNF_via_NFKB signature. We showed that the loss of this signature could be associated with H3K9me3 loss at specific retrotransposable elements . To validate this association, we tested if TNFa treatment...
