Impact of genetic alterations on acute leukemia development
of our research axis
Acute leukemia are cancers of the bone marrow associated with a poor prognosis, mainly sporadic, very rarely some of them having a genetic origin. The development of these cancers results from successive acquisition of mutations (generally between 1 and 5).
We are analyzing the biological mechanisms by which mutations in hematopoietic key genes (mainly PAX5 in B differentiation, GATA2 in myeloid differentiation and USP7 and CHK1 in cell cycle) reprogram normal progenitors to establish a pre-leukemic state and initiate leukemic transformation. Our team uses a multidisciplinary approach on patient samples and mouse models, using CRISPR-Cas9 mutagenesis, ex vivo and in vivo functional assays, flow cytometry, transcriptome and mutation analysis (by next generation sequencing) and high throughput drug screening.
This combined approach allows us to study normal hematopoietic development and the biology of hematopoietic stem cells as well as the oncogenic reprogramming and oncogenic process induced by genomic mutations.
This work is thus part of a fundamental and translational research, with the perspective of identifying new therapeutic agents improving the treatment of acute leukemia, in particular the targeting of leukemic stem cells.
