TranscriptomicsMethylation profiling of pediatric acute promyelocytic leukemia
Acute promyelocytic leukemia (APL) is categorized as the M3 subtype in the French-American-British classification system. It represents a unique subtype of acute myeloid leukemia (AML) characterized by the t(15;17)/PML::RARA fusion, with leukemic cells arrested at the promyelocytic stage of myelopoi...

TranscriptomicsTranscription profiling of human blood from acute promyelocytic leukemia patients using different differentiating agents
Differentiating agents have been proposed to overcome the impaired cellular differentiation in acute myeloid leukemia (AML). However, only the combinations of all-trans retinoic acid or arsenic trioxide with chemotherapy have been successful, and only in treating acute promyelocytic leukemia (also c...

TranscriptomicsSNP data of acute promyelocytic leukemia samples
Acute promyelocytic leukemia (APL) is a hematopoietic malignant disease characterized by the chromosomal translocation t(15;17), resulting in the formation of the PML-RARA gene. Here, 47 t(15;17) APL samples were analyzed with high-density single-nucleotide polymorphism microarray (50K and 250K SNP...

TranscriptomicsDifferential IFNa-stimulated gene expression profiles in PLZF-inducible U937T monocyte cells
Sensitivity to Interferon (IFN) is determined by a complex coordination of genetic and environmental factors. A previous experiment using two renal cancer cell lines differing markedly in their response to IFN were analyzed for their ISG profiles in order to determine gene expression changes associa...

GenomicsPML-RARa/RXR alters the epigenetic landscape in Acute Promyelocytic Leukemia
Many different molecular mechanisms have been suggested to be associated with PML-RAR dependent transformation of haematopoietic progenitors. Here, we investigated the role of PML-RAR and RXR in the organization of epigenetic structures at a genome-wide level. We identified 2722 high confidence PML-...

GenomicsDNA methylation changes are a late event in Acute Promyelocytic Leukemia and coincide with loss of transcription factor binding (sequencing)
The origin of aberrant DNA methylation in cancer remains largely unknown. In this study, we elucidated the DNA methylome in primary Acute Promyelocytic Leukemia (APL) and the role of PML-RARa in establishing these patterns. APL patients showed increased genome-wide DNA methylation with higher variab...

TranscriptomicsChromatin modifications induced by PML-RARalpha repress critical targets in leukemogenesis as analyzed by ChIP-Chip.
A global view of PML-RAR? transcriptional functions was obtained by genome-wide binding and chromatin modification analyses, combined with genome wide expression data. Complete Abstract: The translocation t(15;17) generates the chimeric PML-RAR? transcription factor that is the initiating event of ...

TranscriptomicsAll-trans retinoic reduces the levels of cardiolipins in the NB4 acute promyelocytic leukemia cell-line affecting the autophagy and differentiation responses
All-trans retinoic (ATRA) is used in the treatment of acute promyelocytic leukemia a rare form of AML characterized by the presence of a specific translocation involving chrosomes 15;17 and causing the production of the PML-RARα fusion protein in 95% of the cases. ATRA differentiates the APL blasts...

TranscriptomicsTranscription profiling of Acute Promyelocytic Leukemia samples from patients with wild type FLT3 or FLT3 mutations
In this series we described the gene expression profiles of 18 APL patients using a high density DNA-oligonucleotide microarray (Agilent) representing about 20.000 genes demonstrating the presence of a very uniform expression pattern of APL cases among which two mainly types of gene profiles were re...
