Characterization of the gut-bone marrow axis through bile acid signaling
Communication between the intestine and other organs such as the lungs, brain or bones is mediated by several metabolites, like short-chain fatty acids or bile acids, that relay information about nutritional and microbiota status. Bile acids are endogenous ...
EPFL2024Novel quantitative bioengineered tools to track human bone marrow niche cellular constituents in health and disease
Acute leukemia has a high mortality rate of approximately 50%, and current methods are not effective in predicting disease progression and relapse. To improve our understanding of hematopoiesis and develop new markers for predicting disease relapse in dead ...
EPFL2023New approaches to uncover the minimally functional hematopoietic niche using the adipocytic differentiation axis: pharmacological modulation and adrenal niche induction
Hematopoietic Stem and Progenitor Cells (HSPCs) reside in their niche, a structure that regulates the balance of cellular quiescence, self-renewal and commitment towards differentiated cells. This highly plastic niche is formed by several cellular players, ...
EPFL2022Tcf1 is essential for initiation of oncogenic Notch1-driven chromatin topology in T-ALL
Freddy Radtke, Ute Koch, Nadine Fournier, Marianne Nkosi, Christelle Dubey, Mateusz Waldemar Antoszewski, Tara Kimberly Sugrue, Giovanni Ciriello
NOTCH1 is a well-established lineage specifier for T cells and among the most frequently mutated genes throughout all subclasses of T cell acute lymphoblastic leukemia (T-ALL). How oncogenic NOTCH1 signaling launches a leukemia-prone chromatin landscape du ...
AMER SOC HEMATOLOGY2022Notch1-driven T-ALL chromatin landscape is regulated by Tcf1 in hematopoietic progenitors
Notch1 receptor signaling is essential for T cell fate specification and physiological thymic T lymphocyte development. Its dysregulation and oncogenic activation are detected in almost 80% of pediatric patients suffering from T cell acute lymphoblastic le ...
EPFL2021Metabolic and microenvironmental strategies to accelerate hematopoietic recovery post-aplasia
Vasco Ledebur de Antas de Campos
The procedure-associated mortality rate of bone marrow transplantations (BMT) remains close to 25%. The BMT is therefore only indicated for life-threatening diseases, with no replacement of this technology to be expected in the foreseeable future. Modest i ...
EPFL2019Modeling hematopoietic stem cell dynamics in bioengineered niches
Bone marrow transplantation is a well-established medical procedure for the treatment of various hematologic diseases. However, the relatively low number of hematopoietic stem cells (HSCs) that can be harvested, especially from umbilical cord blood, limits ...
EPFL2019γ-Catenin-Dependent Signals Maintain BCR-ABL1+ B Cell Acute Lymphoblastic Leukemia
Oliver Hantschel, Anja Irmisch
The BCR-ABL1 fusion protein is the cause of chronic myeloid leukemia (CML) and of a significant fraction of adult-onset B cell acute lymphoblastic leukemia (B-ALL) cases. Using mouse models and patient-derived samples, we identified an essential role for γ ...
2019The Multi-kinase Inhibitor Debio 0617B Reduces Maintenance and Self-renewal of Primary Human AML CD34(+) Stem/Progenitor Cells
Michel Aguet, Stefania Rigotti, Maximilien Murone, Andres McAllister
Acute myelogenous leukemia (AML) is initiated and maintained by leukemia stem cells (LSC). LSCs are therapy-resistant, cause relapse, and represent a major obstacle for the cure of AML. Resistance to therapy is often mediated by aberrant tyrosine kinase (T ...
Amer Assoc Cancer Research2017Molecular landscapes of human hematopoietic stem cells in health and leukemia
Blood cells are organized as a hierarchy with hematopoietic stem cells (HSCs) at the root. The advent of genomic technologies has opened the way for global characterization of the molecular landscape of HSCs and their progeny, both in mouse and human model ...
