Replication of Epstein-Barr Viral DNA [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2013
Epstein-Barr virus (EBV) is a paradigm for human tumor viruses: it is the first virus recognized to cause cancer in people; it causes both lymphomas and carcinomas; yet these tumors arise infrequently given that most people in the world are infected with the virus. EBV is maintained extrachromosomally in infected normal and tumor cells.

ATRX promotes maintenance of herpes simplex virus heterochromatin during chromatin stress

open access: yeseLife, 2018
The mechanisms by which mammalian cells recognize and epigenetically restrict viral DNA are not well defined. We used herpes simplex virus with bioorthogonally labeled genomes to detect host factors recruited to viral DNA shortly after its nuclear entry ...

The association of HBV core promoter double mutations (A1762T and G1764A) with viral load differs between HBeAg positive and anti-HBe positive individuals: A longitudinal analysis [PDF]

open access: yes, 2009
Background/Aims: Although there have been a few reports regarding the effect of basal core promoter (BCP) double mutations (A1762T and G1764A) on hepatitis B viral loads, the association remains uncertain.

Evolution of the AGMK1-9T7 GLI1+ progenitor cells to become tumor cells and potentially cancer-stem cells

open access: yesAdvances in Cancer Biology - Metastasis
We have investigated the expression of selected genes and miRNAs that have been found to be associated with human cancer-stem cells for their involvement in the neoplastic evolution of our AGMK1-9T7 cell line from a non-tumorigenic status at passage (p ...

Real-time PCR quantitation of hepatitis B virus DNA using automated sample preparation and murine cytomegalovirus internal control [PDF]

open access: yes, 2005
Quantitation of circulating hepatitis B virus (HBV) DNA is important for monitoring disease progression and for assessing the response to antiviral therapy. Several commercial and 'in house' assays for HBV DNA quantitation have been described but many of

Critical evaluation of HPV16 gene copy number quantification by SYBR green PCR [PDF]

open access: yes, 2008
Background: Human papilloma virus (HPV) load and physical status are considered useful parameters for clinical evaluation of cervical squamous cell neoplasia. However, the errors implicit in HPV gene quantification by PCR are not well documented. We have

Applications of viral metagenomics in the veterinary field [PDF]

open access: yes, 2010
Viral metagenomics provide a powerful technology to investigate the viral flora of healthy and sick animals. Using these methodologies, we gain a better understanding in the etiology of diseases, as well as deepen our knowledge into the viruses ...

Epigenetic control of Epstein Barr Virus transcription – relevance to viral life cycle?

open access: yesFrontiers in Genetics, 2013
DNA-methylation normally leads to silencing of gene expression but Epstein-Barr virus (EBV) provides an exception to the epigenetic paradigm. DNA-methylation is absolutely required for the expression of many viral genes.

Protein-protein interactions leading to recruitment of the host DNA sliding clamp by the hyperthermophilic Sulfolobus islandicus rod- shaped virus 2 [PDF]

open access: yes, 2014
Viruses infecting hyperthermophilic archaea typically do not encode DNA polymerases, raising questions regarding their genome replication. Here, using a yeast two-hybrid approach, we have assessed interactions between proteins of Sulfolobus islandicus ...

Determinazione quantitativa di HIV-1 DNA nel follow-up del paziente HIV-1 infetto: esperienza in un gruppo di soggetti HIV-1 infetti

open access: yesMicrobiologia Medica, 2006
Proviral HIV-1 DNA can represent an alternative viral marker to RNA viral load during the follow-up of HIV-1 infected individuals. Sequential blood samples of 12 patients under antiretroviral treatment from 1997 with two NRTIs, who refused to continue ...
