Polyprotein Precursors to Mouse Mammary Tumor Virus Proteins [PDF]
Journal of Virology, 1979 Mouse mammary tumor virus (MMTV) derived from the culture medium of GR cells contained seven proteins, identified as gp55, gp33, p25, pp20, p16, p12, and p10. The major viral phosphoprotein was the 20,000-molecular-weight protein, pp20. Immunoprecipitation of cytoplasmic extracts from pulse-labeled GR cells identified three MMTV

Molecular Imaging, 2007 Vascular endothelial growth factor (VEGF) is a major inducer of angiogenesis. We generated a transgenic reporter mouse, VEGF-GL, in which an enhanced green fluorescent protein-luciferase fusion protein is expressed under the control of a human VEGF-A ...

The Role of a Betaretrovirus in Human Breast Cancer: Enveloping a Conundrum
Viruses, 2022 Most of the evidence that a human betaretrovirus (HBRV/HMTV) highly related to mouse mammary tumour virus (MMTV) has an etiological role in breast cancer has been summarized in a recent comprehensive Special Issue of “Viruses” entitled “Human ...

Pericentriolar Targeting of the Mouse Mammary Tumor Virus GAG Protein. [PDF]
PLoS ONE, 2015 The Gag protein of the mouse mammary tumor virus (MMTV) is the chief determinant of subcellular targeting. Electron microscopy studies show that MMTV Gag forms capsids within the cytoplasm and assembles as immature particles with MMTV RNA and the Y box ...

Targeting collagen XVIII improves the efficiency of ErbB inhibitors in breast cancer models
The Journal of Clinical Investigation, 2023 The tumor extracellular matrix (ECM) critically regulates cancer progression and treatment response. Expression of the basement membrane component collagen XVIII (ColXVIII) is induced in solid tumors, but its involvement in tumorigenesis has remained ...

Paracrine Transfer of Mouse Mammary Tumor Virus Superantigen [PDF]
The Journal of Experimental Medicine, 1997 Transfer of vSAG7, the endogenous superantigen encoded in the Mtv7 locus, from MHC class II− to MHC class II+ cells has been suggested to occur both in vivo and in vitro. This transfer usually leads to the activation and deletion of T cells expressing responsive Vβs. However, there is no direct molecular evidence for such a transfer.

Cell Reports, 2021 Summary: Basal breast cancer is associated with younger age, early relapse, and a high mortality rate. Here, we use unbiased droplet-based single-cell RNA sequencing (RNA-seq) to elucidate the cellular basis of tumor progression during the specification ...

Advanced Science, EarlyView.Liver stiffness promotes intrahepatic cholesterol accumulation by repressing LXRα through YAP/TAZ activation. Stiff matrices impair cholesterol efflux in hepatocytes, while YAP/TAZ deletion restores LXRα activity and prevents cholesterol‐induced fibrosis.

Advanced Science, EarlyView.ABSTRACT Cancer‐associated fibroblasts (CAFs) are the predominant stromal components within the tumor microenvironment (TME), playing multifaceted roles in cancer progression through dynamic interactions with neoplastic and immune cells. Emerging evidence has revealed remarkable heterogeneity and plasticity of CAFs, which originate from diverse ...
