L'obiettivo dei percorsi BMP e TAZ/TEAD della meccanotrasduzione impedisce la chemioresistenza nel leucemia mieloide acuto.

Despite extensive research and intensive use of chemotherapies in clinics, the 5-year overall survival of acute myeloid leukemia (AML) patients does not exceed 20%. The clonal expansion of leukemic blasts leads to modifications of the bone marrow physical properties, including increased extracellular matrix stiffening, upregulation of intramedullary pressure and reduction of the space available for cells. These biomechanical modifications are speculated to alter therapeutic response and cause treatment resistance. To address this, we herein focused on the role of mechanotransduction pathways in AML. Analysis of primary AML samples or cell lines revealed that BMPR1B and TAZ/TEAD but not YAP l
