## Abstract The expression of the mouse mammary tumor virus (MMTV) in hormone‐induced mammary tumors was investigated by means of a radioimmunoassay for two major MMTV proteins, gp52 and p27. MMTV proteins were isolated on lectin affinity‐ and ion‐exchange chromatography columns. The purified viral

The mouse mammary tumor virus enters mammary epithelial cells via a plasma membrane protein that binds to a viral envelope glycoprotein, gp52. In intact cells, this gp52 receptor can be phosphorylated by activators of protein kinase A and protein kinase C (PKC), but this modification does not occur
Mammary cancer in mice is characterized by progression through defined stages of preneoplasia, with the most common preneoplastic stage being the hyperplastic alveolar nodule (HAN). We determined the relative levels of RNA expression of various cellular proto-oncogenes and endogenous mouse mammary t
## Abstract Mouse mammary tumor virus (MMTV) is a hormonally regulated, oncogenic virus of mice. MMTV‐like virus DNA has previously been detected in human breast cancers, liver disease, and liver cancers. It is hypothesized that local hormonal effects might be of primary importance in determining M
## Abstract A competition radioimmunoassay for purified MTV proteins, MTVp27^gag^ and MTVgp52^env^, was applied to measure the amounts of these proteins in the milk of various mice of Japanese origin. The results were compared to those from European and American strains of high and low mammary canc
