Acute promyelocytic leukemia (APL) is associated with chromosomal translocations resulting in fusion proteins of the retinoic acid receptor (RAR). Here, we report a novel murine model system for APL, based on the transduction of purified murine hematopoietic progenitors (lin(-)) using high-titer retroviral vectors encoding promyelocytic leukemia-RAR (PML-RAR), and the green fluorescent protein ...
The fusion protein promyelocytic leukemia (PML)/retinoic acid receptor (RAR)alpha is tightly linked to the pathogenesis of acute promyelocytic leukemia (APL); hence, it represents a tumor-associated, transformation-related molecule. In this study, three anti-PML adamantyl-conjugated peptide nucleic acid (PNA) oligomers previously described as in vitro inhibitors of PML/RARalpha translation were...
Promyelocytic leukemia protein PML acts as a tumor suppressor, whereas its chimeric mutant promyelocytic leukemia/ retinoic acid receptor (PML/RAR ) causes acute promyelocytic leukemia (APL). Because PML has been shown to form transcription-regulatory complexes with various molecules, we speculated that PML and/or PML/RAR might affect signal transducer and activator of transcription 3 (STAT3) a...
Promyelocytic leukemia zinc finger (PLZF) protein is a sequence-specific DNA-binding protein that represses the transcriptional activity of target genes such as those for cyclin A and the interleukin-3 receptor alpha chain. The PLZF gene becomes fused to the retinoic acid receptor alpha gene as a result of the t(11, 17)(q23;q21) chromosomal translocation that is associated with acute promyelocy...
The fusion protein promyelocytic leukemia (PML)/retinoic acid receptor (RAR)a is tightly linked to the pathogenesis of acute promyelocytic leukemia (APL); hence, it represents a tumor-associated, transformationrelated molecule. In this study, three anti-PML adamantyl-conjugated peptide nucleic acid (PNA) oligomers previously described as in vitro inhibitors of PML/RARa translation were combined...
The role of allogeneic stem cell transplant in advanced acute promyelocytic leukemia patients who received standard first- and second-line therapy is still unknown. We report the outcome of 31 acute promyelocytic leukemia patients (median age 39 years) who underwent allogeneic transplant in second remission (n=15) or beyond (n=16). Sixteen patients were real-time polymerase chain reaction posit...
In acute promyelocytic leukemia (APL), hematopoietic differentiation is blocked and immature blasts accumulate in the bone marrow and blood. APL is associated with chromosomal aberrations, including t(15;17) and t(11;17). For these two translocations, the retinoic acid receptor alpha (RARα) is fused to the promyelocytic leukemia (PML) gene or the promyelocytic zinc finger (PLZF) gene, respectiv...
BACKGROUND The prevalence of and risk factors for central nervous system recurrence in patients with acute promyelocytic leukemia are not well established and remain a controversial matter. DESIGN AND METHODS Between 1996 and 2005, 739 patients with newly diagnosed acute promyelocytic leukemia enrolled in two consecutive trials (PETHEMA LPA96 and LPA99) received induction therapy with all-tra...
Acute myeloid leukemia and acute lymphoblastic leukemia remain devastating diseases. Only approximately 40% of younger and 10% of older adults are long-term survivors. Although curing the leukemia is always the most formidable challenge, complications from the disease itself and its treatment are associated with significant morbidity and mortality. Such complications, discussed herein, include ...
