Homeobox genes are key regulators in normal and malignant hematopoiesis. The human Vent-like homeobox gene VENTX, a putative homolog of the Xenopus laevis Xvent-2 gene, was shown to be highly expressed in normal myeloid cells and in patients with acute myeloid leukemia. We now demonstrate that constitutive expression of VENTX suppresses expression of genes responsible for terminal erythroid dif...
BACKGROUND AND OBJECTIVES The terms acute erythroleukemia and AML-M6 are defined in the FAB classification as proliferations of dysplastic erythroid elements mixed with blasts of myeloid origin, but pure erythroid leukemias are not included. The recent WHO classification has a category of acute myeloid leukemia not otherwise categorized, which includes acute erythroid leukemia (M6) of two subty...
Detailed characterization of the composite phenotype of two newly established erythroleukemia lines (OCIM1, OCIM2) shows that these lines share many of their erythroid markers (ie, surface antigens and globin program) as well as several of their nonerythroid properties (myeloid/monocytic/megakaryocytic) with the two known erythroleukemia lines (K562, HEL). In addition, each displays novel and i...
Our previous cell fusion experiments have suggested that the in vitro erythroid differentiation of mouse erythroleukemia cells is the result of a synergistic reaction involving two intracellular differentiation-inducing factors (DIF); these were subsequently demonstrated in the cytoplasmic fraction of mouse erythroleukemia cells. Here, we present experimental evidence indicating that, under con...
We introduced a normal chromosome 11 into GM979 murine erythroleukemia cells by fusing them with Epstein-Barr virus-transformed lymphocytes from a normal individual. In contrast to previous data obtained with other murine erythroleukemia cells, we detected activation of human chromosomal gamma-globin genes in GM979 cells. GM979, unlike previously used murine erythroleukemia cell lines, expresse...
We report the case of a man with acute erythroleukemia (AML-M6), who developed myelodysplastic syndrome (MDS) involving U2AF1 mutation 8 years after HLA-matched unrelated bone marrow transplantation. It’s donor cell origin which proved by molecular analysis using Short Tandem Repeat (STR) sequences. To our knowledge, this is the first case that usage of demethylation drug in DCL patient. The re...
