Mutant ASXL1 induces age-related expansion of phenotypic hematopoietic stem cells through activation of Akt/mTOR pathway

ASXL1 mutations are frequently found in age-related clonal haemaotopoiesis (CH), but how they drive CH is unclear. Here the authors show that expression of C-terminal truncated ASXL1 in haematopoietic stem cells (HSCs) leads to Akt de-ubiquitination, activated Akt/mTOR signaling, and aberrant HSC pr...
