Abstract excerpt
Systemic mastocytosis (SM) either presents as a malignant neoplasm with short survival or as an indolent disease with normal life expectancy. In both instances, neoplastic mast cells (MCs) harbor D816V-mutated KIT, suggesting that additional oncogenic mechanisms are involved in malignant transformation. We here describe that Lyn and Btk are phosphorylated in a KIT-independent manner in neoplastic MCs in advanced...
