Cryoelectron Microscopy of Mouse Mammary Tumor Virus [PDF]
ABSTRACT Cryoelectron microscopy of Mouse mammary tumor virus , a Betaretrovirus , provided information about glycoprotein structure and core formation. The virions showed the broad range of diameters typical of retroviruses.

Conditionally reprogrammed normal and transformed mouse mammary epithelial cells display a progenitor-cell-like phenotype. [PDF]
Mammary epithelial (ME) cells cultured under conventional conditions senesce after several passages. Here, we demonstrate that mouse ME cells isolated from normal mammary glands or from mouse mammary tumor virus (MMTV)-Neu-induced mammary tumors, can be ...

Generation of a novel MMTV-tTA transgenic mouse strain for the targeted expression of genes in the embryonic and postnatal mammary gland. [PDF]
We have generated a new and improved transgenic mouse strain that permits a temporally controlled expression of transgenes throughout mammary gland development.

Low prevalence of human mammary tumor virus (HMTV) in breast cancer patients from Myanmar
Background Human mammary tumor virus (HMTV) is 90–95% homologous to mouse mammary tumor virus (MMTV), one of the causal agents of murine mammary tumors.

Mouse Mammary Tumor Virus Infects Human Cells [PDF]
Abstract Mouse mammary tumor virus (MMTV) has long been speculated to be involved in human breast cancer and more recently in human primary biliary cirrhosis. Despite complete proviral sequences markedly homologous to MMTV being identified in human breast cancer tissue, no convincing evidence has been presented to date that MMTV can ...

Amplification of mouse mammary tumor virus genomes in non-mammary tumor cells [PDF]
Extra proviral copies of mouse mammary tumor virus (MMTV) are known to be present in the genomes of certain T-cell lymphomas of mice. Analysis of additional non-mammary tumor cell types known to express MMTV transcripts and antigens revealed the presence of extra acquired MMTV proviruses in a pituitary tumor cell line, a macrophage line, and Leydig ...

Apc mutation enhances PyMT-induced mammary tumorigenesis.
The Adenomatous Polyposis Coli (APC) tumor suppressor gene is silenced by hypermethylation or mutated in up to 70% of human breast cancers. In mouse models, Apc mutation disrupts normal mammary development and predisposes to mammary tumor formation ...

Tumorigenesis is often described as a result of accumulated mutations that lead to growth advantage and clonal expansion of mutated cells. There is evidence in the literature that cancer cells are influenced by the microenvironment.
