Murine mammary tumor virus: characterization of infection of nonmurine cells

Journal of Virology, 1976
Murine mammary tumor virus (MuMTV) was used to productively infect feline and mink cells. MuMTV "proviral" DNA could be detected in the infected cells by molecular hybridization using radioactive MuMTV complementary DNA as a probe. Kinetic analysis of MuMTV proviral DNA synthesis after infection showed that maximum MuMTV DNA synthesis was achieved by 8

Ultrastructure of Tumor Cells in Marek's Disease Virus-Infected Chickens

American Journal of Veterinary Research, 1973
SUMMARY Marek's disease (md) visceral tumors from 5½-week-old chickens exposed to the GA isolate of md herpsvirus (mdhv) were examined by electron microscopy determine the fine structure of the lesion. In contrast to the neural lesions of md, which are composed of a mixture of cell types, the visceral tumors contained only one cell type, an immature ...

Abrogation of infectivity of mouse mammary tumor virus by reserpine

Experimental pathology, 1982
Summary Treatment of mouse mammary tumor virus (MMTV) with reserpine in vitro or administration of reserpine 30 min after MMTV inoculation abolishes the viral infectivity in mice.

Superantigen-induced immune stimulation amplifies mouse mammary tumor virus infection and allows virus transmission

Cell, 1993
Endogenous and infectious mouse mammary tumor viruses (MMTVs) encode in their 3' long terminal repeat a protein that exerts superantigen activity; that is, it is able to interact with T cells via the variable domain of the T cell receptor (TCR) beta chain.

BK Virus, JC Virus and Simian Virus 40 Infection in Humans, and Association with Human Tumors

2007
BK virus (BKV), JC virus (JCV) and Simian Virus 40 (SV40) are polyomaviruses, highly homologous at the DNA and protein levels. While the human polyomaviruses BKV and JCV are ubiquitous in humans, SV40 is a simian virus which was introduced in the human population, between 1955 and 1963, by contaminated poliovaccines produced in SV40-infected monkey ...

Hepatitis B virus infection associated with hematopoietic tumors.

The American journal of pathology, 1994
Hepatitis B virus (HBV) infection and replication have been linked to the development of hepatocellular carcinoma. Bone marrow-derived cells, as well as mesenchymal and epithelial cells, were recently shown to support HBV replication. We hypothesize that the mechanism that links HBV infection and liver tumors might also promote tumor development in ...

Testicular germ cell tumors in patients with human immunodeficiency virus infection

Cancer, 1996
There has been evidence of a higher incidence of testicular germ cell tumors (GCT) in human immunodeficiency virus (HIV)-seropositive men than in the non HIV-infected male population. Most authors recommend standard therapy for HIV-positive patients with GCT but the immumosuppressive effects of chemotherapy and/or radiotherapy must be considered.The ...

Enhanced tumor susceptibility of immunocompetent mice infected with lymphocytic choriomeningitis virus

Cancer Immunology, Immunotherapy, 1990
Mice infected i.v. with high doses of lymphocytic choriomeningitis virus (LCMV; 10(5)-10(6) plaque-forming units) 8-10 days prior to challenge with the methylcholanthrene-induced fibrosarcoma tumor cell line MC57G or the melanoma cell line B16 tumor cells showed an enhanced tumor susceptibility with respect to both growth kinetics of the tumor and the ...

Infection of cultured rat hepatoma cells by mouse mammary tumor virus

Cell, 1977
A continuous line of buffalo rat hepatoma (HTC) cells has been successfully infected with mouse mammary tumor virus (MMTV) produced by the GR mammary tumor cell line. Uniform infection required initial exposure of the HTC cells to greater than 10(5) MMTV particles per cell.

Lectin Binding Studies on RNA Tumor Virus-Infected Cells

Proceedings, annual meeting, Electron Microscopy Society of America, 1975
The abilities of plant lectins to preferentially agglutinate malignant cells and to bind to specific monosaccharide or oligosaccharide sequences of glycoproteins and glycolipids make them a new and important biochemical probe for investigating alterations in plasma membrane structure which may result from malignant transformation.
