    Clonal Hematopoiesis, Myeloid Disorders and BAX-Mutated Myelopoiesis in Patients Receiving Venetoclax for CLL

    As BCL2 was an important determinant of survival of both myeloid progenitor and B cells, researchers investigated whether clinical and molecular abnormalities arose in the myeloid compartment during long-term continuous venetoclax treatment of chronic lymphocytic leukemia in 89 patients.

    Abstract

    Inhibition of Oxidized Nucleotide Sanitation by TH1579 and Conventional Chemotherapy Cooperatively Enhance Oxidative DNA-Damage and Survival in AML

    Investigators demonstrated that MutT homolog 1 was a potential druggable target expressed by the majority of AML patients and the inv(16)/KITD816Y AML mouse model mimicking the genetics of AML patients exhibiting poor response to standard chemotherapy.
