A Collaborative Approach to Addressing PML: The PML Consortium

PML Degradation: Multiple Ways to Eliminate PML

The promyelocytic leukemia tumor suppressor gene (PML) critically regulates several cellular functions that oppose tumorigenesis such as oncogene-induced senescence, apoptosis, the response to DNA damage and to viral infections. PML deficiency occurs commonly in a broad spectrum of human cancers through mechanisms that involve its aberrant ubiquitination and degradation. Furthermore, several vi...

Perspectives in PML: a unifying framework for PML function.

The promyeloctyic leukemia protein (PML) has established activities as a potent repressor of proliferation, and oncogenic transformation, a promoter of apoptosis, an inducer of senescence, and may act as an inhibitor of angiogenesis in mammalian systems. Loss of PML or its nuclear bodies is associated with many human disease states. At the molecular level, the PML protein, and its associated nu...

Opposing effects of PML and PML/RAR on STAT3 activity

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...

Regulation of NF-κB by PML and PML-RARα

Promyelocytic Leukemia (PML) is a nuclear protein that forms sub-nuclear structures termed nuclear bodies associated with transcriptionally active genomic regions. PML is a tumour suppressor and regulator of cell differentiation. We demonstrate that PML promotes TNFα-induced transcriptional responses by promoting NF-κB activity. TNFα-treated PML-/- cells show normal IκBα degradation and NF-κB n...
