IPSS classification defines low risk (Low and Intermediate 1), and high risk (Intermediate 2 and High) MDS. High-risk MDS (MDS-HR) have a high risk of transformation into acute leukemia with multilineage dysplasia (AML-DML). The success of Azacitidine has been mainly achieved through a rigorous empirical and clinical research, but the molecular mechanisms by which this molecule exerts its effects remain poorly characterized. The primary mode of action of Azacytidine is through DNA demethylation, and integration in to mRNA that favor traduction inhibition. The impact of this molecule on various cell death programs involved in the elimination of leukemic cells : apoptosis and autophagy is currently poorly known.\n\nThe research program and clinical studies we proposed focus on two major aspects:\n\n\\- Main objective: Molecular mechanism of action and resistance to Azacitidine: Role of apoptosis versus autophagy.\n\n\\- Secondary Objective: Reversion of Azacytidine resistance using different drugs targeting apoptosis and\u002For autophagy. Our laboratory has identified new molecules to selectively induce different types of cell death (apoptosis or autophagy).",[24],"Myelodysplastic Syndromes or Acute Myeloid Leukemia With Multilineage Dysplasia","RECRUITING","2025-03-17",{"date":28,"type":29},"2025-03-19","ACTUAL",{"date":31,"type":4},"2010-09",{"date":33,"type":20},"2025-09",{"name":35,"class":36},"Centre Hospitalier Universitaire de Nice","OTHER",4]
