Oncogenic viruses and their role in tumor formation [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo, 2005
Oncogenic viruses trigger persistent infections, which can stimulate uncontrolled cell growth by inducing cell transformation. Different oncogenic viruses use different mechanisms for infecting cells.

Differential Regulation of Cellular FAM111B by Human Adenovirus C Type 5 E1 Oncogenes

open access: yesViruses, 2021
The adenovirus type 5 (HAdV-C5) E1 transcription unit encodes regulatory proteins that are essential for viral replication and transformation. Among these, E1A and E1B-55K act as key multifunctional HAdV-C5 proteins involved in various steps of the viral

The Role of microRNAs, Long Non-coding RNAs, and Circular RNAs in Cervical Cancer

open access: yesFrontiers in Oncology, 2020
Prolonged infection of uterine cervix epithelium with human papillomavirus (HPV) and constitutive expression of viral oncogenes have been recognized as the main cause of the complex molecular changes leading to transformation of cervical epithelial cells.

The eEF1A proteins: at the crossroads of oncogenesis, apoptosis and viral infections.

open access: yesFrontiers in Oncology, 2015
Eukaryotic translation elongation factors 1 alpha, eEF1A1 and eEF1A2, are not only translation factors, but also pleiotropic proteins that are highly expressed in human tumors, including breast cancer, ovarian cancer and lung cancer.

Liver Cell Transformation in Chronic HBV Infection

open access: yesViruses, 2009
Epidemiological studies have provided overwhelming evidence for a causal role of chronic HBV infection in the development of hepatocellular carcinoma (HCC), but the molecular mechanisms underlying virally-induced tumorigenesis remain largely debated.

In vivo antagonistic role of the Human T-Cell Leukemia Virus Type 1 regulatory proteins Tax and HBZ.

open access: yesPLoS Pathogens, 2021
Adult T cell leukemia (ATL) is an aggressive malignancy secondary to chronic infection by the human T-cell leukemia virus type 1 (HTLV-1) infection. Two viral proteins, Tax and HBZ, play central roles in ATL leukemogenesis.

Epstein-Barr virus provides a new paradigm: a requirement for the immediate inhibition of apoptosis. [PDF]

open access: yesPLoS Biology, 2005
DNA viruses such as herpesviruses are known to encode homologs of cellular antiapoptotic viral Bcl-2 proteins (vBcl-2s), which protect the virus from apoptosis in its host cell during virus synthesis.

Viral DNA in Polyoma- and SV40-Transformed Cell Lines [PDF]

open access: yesProceedings of the National Academy of Sciences, 1968
It is clear that cells transformed by the small DNA-containing viruses, polyoma virus (Py) and SV40, harbor the viral DNA since they contain viral mRNA,1 and some lines even yield infectious virus after fusion with cells able to support the multiplication of the virus.2, 3 Very little is known, however, about the state of the viral DNA in these cells ...

Malignant transformation of canine oral papillomavirus (CPV1)-associated papillomas in dogs: An emerging concern?

open access: yesPapillomavirus Research, 2018
Canine oral papillomavirus (CPV1, also known as COPV), the most common cause of non-neoplastic papillomas, has not been shown to cause squamous cell carcinomas (SCC).

Viral genome integration of canine papillomavirus 16

open access: yesPapillomavirus Research, 2019
Papillomaviruses infect humans and animals, most often causing benign proliferations on skin or mucosal surfaces. Rarely, these infections persist and progress to cancer.
