Transcription and methylation analyses of preleukemic promyelocytes indicate a dual role for PML/RARA in leukemia initiation.
Acute promyelocytic leukemia is an aggressive malignancy characterized by the accumulation of promyelocytes in the bone marrow. PML/RARA is the primary abnormality implicated in this pathology, but the mechanisms by which this chimeric fusion protein initiates disease are incompletely understood. Identifying PML/RARA targets in vivo is critical for comprehending the road to pathogenesis. Utiliz...
متن کاملCytogenetic and FMS-Like Tyrosine Kinase 3 Mutation Analyses in Acute Promyelocytic Leukemia Patients
Background: The secondary genetic changes other than the promyelocytic leukemia-retinoic acid receptor (PML-RARA) fusion gene may contribute to the acute promyelocytic leukemogenesis. Chromosomal alterations and mutation of FLT3 (FMS-like tyrosine kinase 3) tyrosine kinase receptor are the frequent genetic alterations in acute myeloid leukemia. However, the prognostic significance of FLT3 mutat...
متن کاملExpression and Function of PML-RARA in the Hematopoietic Progenitor Cells of Ctsg-PML-RARA Mice
Because PML-RARA-induced acute promyelocytic leukemia (APL) is a morphologically differentiated leukemia, many groups have speculated about whether its leukemic cell of origin is a committed myeloid precursor (e.g. a promyelocyte) versus an hematopoietic stem/progenitor cell (HSPC). We originally targeted PML-RARA expression with CTSG regulatory elements, based on the early observation that thi...
متن کاملAcute myeloid leukemia pretreated with filgrastim mimicking acute promyelocytic leukemia.
A 66-year-old man with a history of hepatitis C virus and liver transplantation presented to the emergency department for shortness of breath. He had received weekly filgrastim for chronic neutropenia, and immediately before admission he had received 3 days of filgrastim and 1 day of pegfilgrastim. A hemogram showed a white blood cell count of 4.54 K/mL with 23% blastic cells. Emergent bone mar...
متن کاملHIF factors cooperate with PML-RARa to promote acute promyelocytic leukemia progression and relapse
Acute promyelocytic leukemia (APL) is epitomized by the chromosomal translocation t(15;17) and the resulting oncogenic fusion protein PML-RARa. Although acting primarily as a transcriptional repressor, PML-RARa can also exert functions of transcriptional co-activation. Here, we find that PML-RARa stimulates transcription driven by HIF factors, which are critical regulators of adaptive responses...
