TET3 and chronic myelomonocytic leukemia: The authors demonstrated that unrepressed expression levels of the Tet methylcytosine dioxygenase 3 (Tet3) gene led to a decrease in the levels of Ly6C− monocytes in miRNA-150–deficient mice, highlighting the clinical implications that diminished expression of miRNA-150 mostly found in the peripheral blood CD14+ monocytes of patients with chronic myelomonocytic leukemia.
