Ultrastructural features of the intestinal absorption of mouse mammary tumor virus in newborn BALB/cfRIII mice.

open access: yes, 1989
The retrovirus mouse mammary tumor virus is present in mouse strains with a high incidence of mammary tumors as a causative agent. It is produced mainly in the mammary glands of sexually mature females and is milk-transmitted to newborns. The fate of the

White Adipose Tissue Browning and Cross Talk With Metabolic Diseases and Tumors: From Molecular Mechanisms to Clinical Translation

open access: yesMed Research, Volume 2, Issue 2, Page 280-308, June 2026.
White adipose tissue undergoes browning under endogenous and exogenous stimuli, primarily regulated by core molecules such as PRDM16 and UCP1. It exhibits a double‐edged sword effect in metabolic diseases and tumors: while mitigating metabolic disease impacts and suppressing early‐stage tumors through nutritional competition, it may accelerate cachexia

B and T cells are required for mouse mammary tumor virus spread within the mammary gland.

open access: yes, 1998
Mouse mammary tumor virus (MMTV) is an infectious retrovirus transmitted through milk from mother to newborns. MMTV encodes a superantigen (SAg) whose activity is indispensable for the virus life cycle, since a genetically engineered virus with a ...

Dmp1α inhibits HER2/neu-induced mammary tumorigenesis.

open access: yesPLoS ONE, 2013
Our recent study shows a pivotal role of Dmp1 in quenching hyperproliferative signals from HER2 to the Arf-p53 pathway as a safety mechanism to prevent breast carcinogenesis.

Oxygen‐independent expression of HIF‐1α during the cell cycle in hepatocellular carcinoma cells controls essential metabolic pathways under normoxia

open access: yesThe FEBS Journal, Volume 293, Issue 11, Page 3140-3165, June 2026.
Intra‐tumoral oxygen deprivation (hypoxia) promotes the activation of hypoxia‐inducible factors (HIFs) that orchestrate the transcriptional adaptation of cancer cells to hypoxia. Hypoxia is prevalent in hepatocellular carcinoma (HCC), a cancer type with limited therapeutic options.

A Novel Mechanism of Resistance to Mouse Mammary Tumor Virus Infection

open access: yes, 2000
Exogenous mouse mammary tumor virus (MMTV) is carried from the gut of suckling pups to the mammary glands by lymphocytes and induces mammary gland tumors. MMTV-induced tumor incidence in inbred mice of different strains ranges from 0 to as high as 100%

Mammary gland expression of mouse mammary tumor virus is regulated by a novel element in the long terminal repeat.

open access: yes, 1999
Mouse mammary tumor virus (MMTV) infects both lymphoid tissue and lactating mammary gland during its infectious cycle, but some endogenous MMTVs are transcribed only in lymphoid cells.

Titrations of various mouse mammary tumor viruses in different mouse strains

open access: yes, 1974
SUMMARY-Milks from the high-mammary-tumor mouse strains, A, BALB/cfC3H, Rill, and C3H were titrated for infectivity in low-mammary-tumor strains C57BL, BALB/c, Af, and Rlllf.

The Role Of Mouse Mammary Tumor Virus In The Induction And Progression Of Mouse Mammary Tumors [PDF]

open access: yes, 1986
Mouse mammary tumor virus (MMTV) is a retrovirus which causes mammary tumors in many strains of mice. An essential part of the viral life cycle involves the integration of a double-stranded DNA provirus into the host cell genome. Tumorigenesis is thought to be mediated by such integrated proviruses.;Restriction endonuclease analysis of the DNA from a ...

Morphologic and Antigenic Properties of Mouse Mammary Tumor Virus Produced in a Hormone-Responsive Fashion by C57B1/10 Mammary Tumors of Non-Viral Origin

open access: yes, 1988
Bl-MaTU/A1 mouse mammary tumor cells, derived from a C57B1/10 mammary adenocarcinoma induced by dimethylbenzanthracene and mammotropic hormones, express virus particles and proteins related to mouse mammary tumor virus (MMTV).
