Intrinsic antiviral resistance mediated by constitutively expressed cellular proteins is one arm of defence against virus infection. Promyelocytic leukaemia nuclear bodies (PML-NBs, also known as ND10) contribute to host restriction of herpes simplex virus type 1 (HSV-1) replication via mechanisms that are counteracted by viral regulatory protein ICP0. ND10 assembly is dependent on PML, which c...

Approximately 10% of gastric carcinomas (GC) are comprised of cells latently infected with Epstein-Barr virus (EBV); however, the mechanism by which EBV contributes to the development of this malignancy is unclear. We have investigated the cellular effects of the only EBV nuclear protein expressed in GC, EBNA1, focusing on promyelocytic leukemia (PML) nuclear bodies (NBs), which play important ...

The complex-frequency-shifted perfectly matched layer CFS-PML technique can efficiently absorb near-grazing incident waves. In seismic wave modeling, CFS-PML has been implemented by the first-order-accuracy convolutional PML technique or second-order-accuracy recursive convolution PML technique. Both use different algorithms than the numerical scheme for the interior domain to update auxiliary ...

The mechanism responsible for hepatitis B virus (HBV) exacerbation during chemotherapy and radiotherapy remains unknown. We investigated whether the activation of DNA repair pathways influences HBV replication. The upregulation of the promyelocytic leukemia (PML) protein and its associated PML nuclear body (PML-NB) by chemotherapy and irradiation-induced DNA repair signaling correlated with the...

PG-M3 is a new monoclonal antibody (MoAb) specifically directed against a peptide sequence located in the aminoterminal region of the human PML protein. PML gene fuses with the retinoic acid receptor alpha (RAR alpha) gene during the t(15; 17) chromosomal translocation of acute promyelocytic leukemia (APL). The epitope recognized by PG-M3 is species-specific and fixative-resistant and is shared...

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...

Herpes simplex virus type 1 (HSV-1) is a significant human pathogen that infects a large portion of the human population. Cells deploy a variety of defenses to limit the extent to which the virus can replicate. One such factor is the promyelocytic leukemia (PML) protein, the nucleating and organizing factor of nuclear domain 10 (ND10). PML responds to a number of stimuli and is implicated in in...

The promyelocytic leukemia (PML) tumor suppressor of acute promyelocytic leukemia (APL) is essential for a number of proapoptotic and growth-suppressive pathways as well as for the activity of differentiating agents such as retinoic acid (RA). In human APL, the dose of PML is reduced to heterozygosity given that one allele is involved in the chromosomal translocation while the status of the rem...

Promyelocytic leukemia (PML) bodies have been implicated in a variety of cellular processes, such as cell-cycle regulation, apoptosis, proteolysis, tumor suppression, DNA repair and transcription. Despite this, the function of PML bodies is still unknown. Direct and indirect evidence supports the hypothesis that PML bodies interact with specific genes or genomic loci. This includes the finding ...

BACKGROUND Novel immunosuppressive/modulating therapies with monoclonal antibodies (MABs) have been associated with progressive multifocal leukoencephalopathy (PML), a potentially fatal disease of the brain caused by the JC virus. Taking the complex diagnostic testing and heterogeneous clinical presentation of PML into account, an agreed case definition for PML is a prerequisite for a thorough ...
