Modulation of CREB binding protein function by the promyelocytic (PML) oncoprotein suggests a role for nuclear bodies in hormone signaling.

چکیده
Disaggregation of the spherical nuclear bodies termed promyelocytic (PML) oncogenic domains (PODs) is a characteristic of acute promyelocytic leukemia. Here, we demonstrate that the cAMP enhancer binding protein (CREB)-binding protein (CBP) associates with PML in vitro and is recruited to the PODs in vivo. Through its association with CBP, wild-type PML dramatically stimulates nuclear receptor transcriptional activity. These results demonstrate that a fraction of CBP is compartmentalized to the POD through its association with PML and thus suggest that PML and other POD-associated proteins may play an unexpectedly broad role in aspects of transcriptional regulation and human disease.

The Tax oncoprotein promotes cellular transformation and is associated with the pathogenesis of adult T-cell leukemia. Tax expression activates transcription via the cAMP enhancer binding proteinyactivating transcription factor (CREByATF) and NF-kB pathways. In contrast to its positive action, here we demonstrate that Tax is a potent repressor of steroid and retinoid receptor transcription. The...
متن کاملAcute promyelocytic leukemia, arsenic, and PML bodies
Acute promyelocytic leukemia (APL) is driven by a chromosomal translocation whose product, the PML/retinoic acid (RA) receptor α (RARA) fusion protein, affects both nuclear receptor signaling and PML body assembly. Dissection of APL pathogenesis has led to the rediscovery of PML bodies and revealed their role in cell senescence, disease pathogenesis, and responsiveness to treatment. APL is rema...

In the present study, using anti-sense oligonucleotides the inhibition of expression of the PML protein hasbeen investigated. The anti-sense oligonucleotides were designed against the translation initiation site ofthe PML gene, and their effects were investigated on cellular growth and DNA synthesis. Incubation of normalhuman fibroblast cells with the anti-sense oligonucleotid...
متن کاملAn arenavirus RING (zinc-binding) protein binds the oncoprotein promyelocyte leukemia protein (PML) and relocates PML nuclear bodies to the cytoplasm.
The promyelocytic leukemia protein (PML) forms nuclear bodies which are altered in some disease conditions. We report that the cytoplasmic RNA virus lymphocytic choriomeningitis virus (LCMV) influences the distribution of PML bodies. In cells infected with LCMV, the Z protein and PML form large bodies primarily in the cytoplasm. Transient transfection studies indicate that Z alone is sufficient...
متن کاملAnalysis of Promyelocytic Leukemia in Human Embryonic Carcinoma Stem Cells During Retinoic Acid-Induced Neural Differentiation
Background: Promyelocytic leukemia protein (PML) is a tumor suppressor protein that is involved in myeloid cell differentiation in response to retinoic acid (RA). In addition, RA acts as a natural morphogen in neural development. Objectives: This study aimed to examine PML gene expression in different stages of in vitro neural differentiation of NT2 cells, and to investigate the possible role o...
