Acute promyelocytic leukemia (APL) is characterized by the specific chromosome translocation t(15;17) with promyelocytic leukemia-retinoic acid receptor-alpha (PML-RARA) fusion gene and the ability to undergo terminal differentiation as an effect of all-trans retinoic acid (ATRA). Recently, arsenic trioxide (As(2)O(3)) has been identified as an alternative therapy in patients with both ATRA-sen...
We utilized a mouse model of acute promyelocytic leukemia (APL) to investigate how aberrant activation of cytokine signaling pathways interacts with chimeric transcription factors to generate acute myeloid leukemia. Expression in mice of the APL-associated fusion, PML-RARA, initially has only modest effects on myelopoiesis. Whereas treatment of control animals with interleukin-3 (IL-3) resulted...
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...
Acute promyelocytic leukemia (APL) is a specific malignant hematological disorder with a diagnostic hallmark of chromosome translocation t(15;17)(q22;q21). As a very rare secondary cytogenetic aberration in pediatric APL, ider(17q) (q10)t(15;17) was suggested to be a poor prognostic factor based on previous case reports.Here, we report a pediatric APL case with a rare karyotype of ider(17)(q10)...
Perturbation in the transcriptional control of genes driving differentiation is an established paradigm whereby oncogenic fusion proteins promote leukemia. From a retinoic acid (RA)-sensitive acute promyelocytic leukemia (APL) cell line, we derived an RA-resistant clone characterized by a block in transcription initiation, despite maintaining wild-type PML/RARA expression. We uncovered an aberr...
Wilms' tumor gene 1 (WT1) expression is a well-known predictor for relapse in acute myeloid leukemia. We monitored WT1 decrement along the treatment course to identify its significant role as a marker for residual disease in acute promyelocytic leukemia (APL) and tried to suggest its significance for relapse prediction. In this single center retrospective study, we serially measured PML-RARa an...
Acute promyelocytic leukemia (APL) is a highly curable disease with excellent complete remission and long-term survival rates. However, the development of therapy-related myeloid neoplasms (t-MN) is being reported with increasing frequency in patients successfully treated for APL. We attempted to clarify the different clinical features and hematologic findings between t-MN and relapse cases, an...
