Laminin, long thought to be only a structural support protein in the microenvironment of breast and other epithelial tissue, is "famous" for its cross-like shape. However, laminin is far more than just a support player with a "pretty face." Two studies led by one of the world's foremost breast cancer scientists have shown how laminin plays a central role in the development of breast cancer, the second most leading cause of cancer death among women in the United States. In one study it was...

By Elizabeth K. Gardner, Purdue University Purdue University researchers have reproduced portions of the female breast in a tiny slide-sized model dubbed "breast on-a-chip" that will be used to test nanomedical approaches for the detection and treatment of breast cancer. The model mimics the branching mammary duct system, where most breast cancers begin, and will serve as an "engineered organ" to study the use of nanoparticles to detect and target tumor cells within the ducts. Sophie Lelivre,...

Max Planck researchers discover novel mechanism for vertebrate organ development Hormones, growth factors and several proteins ensure that development occurs in the right way, at the right time. The components that cause breast development in mammals, for example, were thought to be largely known. However, as a team of scientists from Göttingen, Frankfurt and Hanover have now discovered, in the case of breast development, hormones and proteins do not account for the full story. The...

If women had no prolactin receptors on cells in their mammary glands, they would not produce milk when they were nursing. Prolactin receptors are also found in other organs including the lung and the colon. The only problem is that these receptors are sort of like cellular wiring, and when the wrong conditions bring them together, the resulting short circuit can produce cancer. In new research published online Oct. 18, 2010, in the Proceedings of the National Academy of Science, a team led by...

New research uncovers a case of mistaken identity that may have a significant impact on future breast cancer prevention and treatment strategies. The study, published by Cell Press in the September 3rd issue of the journal Cell Stem Cell, suggests that despite their "stem cell-like" characteristics, most aggressive breast tumors are not derived from normal mammary gland stem cells. The glandular tissue of the breast contains two main cell types, outer "basal" cells and inner "luminal" cells....

Girls eating a high-fat diet during puberty, even those who do not become overweight or obese, may be at a greater risk of developing breast cancer later in life, according to Michigan State University researchers. The implications - that a high-fat diet may have detrimental effects independent of its effect to cause obesity - could drive new cancer prevention efforts. The findings come from research at MSU's Breast Cancer and the Environment Research Center, established in 2003 and funded...

Research implications include breast tissue regeneration and new cancer drug targets For the first time, researchers at Fred Hutchinson Cancer Research Center have identified and isolated adult mammary stem cells in mice. Long-term implications of this research may include the use of such cells to regenerate breast tissue, provide a better understanding of the role of adult stem cells in breast cancer development, and develop potential new targets for anti-cancer drugs. The findings, by Larry...

Researchers at the Walter and Eliza Hall Institute have discovered that breast stem cells are exquisitely sensitive to the female hormones estrogen and progesterone, a finding that opens the way for the development of new preventions and treatments for breast cancer. The discovery, by scientists in the institute's Stem Cells and Cancer and Bioinformatics divisions, also explains decades of evidence linking breast cancer risk to exposure to female hormones. It has been published online today...

Social isolation and related stress could contribute to human breast cancer susceptibility, research from a rat model designed at the University of Chicago to identify environmental mechanisms contributing to cancer risk shows. The researchers found that isolation and stress result in a 3.3-fold increase in the risk of developing cancer among rats with naturally occurring mammary tumors. The research establishes, for the first time, that isolation and stress could be a factor in human breast...

Researchers have found that hormones produced during pregnancy induce a protein that directly inhibits the growth of breast cancer. This protein, alpha-fetoprotein (AFP), may serve as a viable, well-tolerated agent for the treatment and prevention of breast cancer, according to findings published in Cancer Prevention Research, a journal of the American Association for Cancer Research. "Hormones in pregnancy, such as estrogen, all induce AFP, which directly inhibits the growth of breast...

The Common House Mouse (Mus musculus), is the most numerous species of the genus Mus. It is the most common and populous mammalian species on earth, besides humans. House mice almost always live in close proximity to humans. Laboratory mice belong to strains of house mice and are some of the most important model organisms in biology and medicine. They are by far the most commonly used laboratory mammal. House mice are light brown to black, with short hair and a light belly. The ears and...
