It is well-known that the risks of breast cancer increase dramatically for women over the age of 50, but what takes place at the cellular level to cause this increase has been a mystery. Some answers and the possibility of preventative measures in the future are provided in a new study by researchers at the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab). Mark LaBarge, a cell and molecular biologist in Berkeley Lab´s Life Sciences Division,...

Breast-cancer researchers at the University of Wisconsin-Madison have found that two related receptors in a robust signaling pathway must work together as a team to maintain normal activity in mammary stem cells. Mammary stem cells produce various kinds of breast cell types. They may also drive the development and growth of malignant breast tumors. Published recently in the Journal of Biological Chemistry, the research also suggests that a new signaling pathway may be involved, a...

Study adds to growing health concerns about common plastic additive A new study finds that fetal exposure to the plastic additive bisphenol A, or BPA, alters mammary gland development in primates. The finding adds to the evidence that the chemical can be causing health problems in humans and bolsters concerns about it contributing to breast cancer. "Previous studies in mice have demonstrated that low doses of BPA alter the developing mammary gland and that these subtle changes increase...

Breast cancer cells are more aggressive the longer they're exposed to cadmium Studies by researchers at Dominican University of California show that breast cancer cells become increasingly aggressive the longer they are exposed to small concentrations of cadmium, a heavy metal commonly found in cosmetics, food, water and air particles. The study by Maggie Louie, associate professor of biochemistry, shows exposure to cadmium for prolonged periods of time can cause the progression of...

Purdue University researchers have created a new imaging technology that reveals subtle changes in breast tissue, representing a potential tool to determine a woman's risk of developing breast cancer and to study ways of preventing the disease. The researchers, using a special "3-D culture" that mimics living mammary gland tissue, also showed that a fatty acid found in some foods influences this early precancerous stage. Unlike conventional cell cultures, which are flat, the 3-D cultures...

In a study that holds major implications for breast cancer research as well as basic cell biology, scientists with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini. This rotation, which the researchers call “CAMo,” for coherent angular motion, is necessary for the cells to...

Protein Assists The Spread Of Breast Cancer
2012-01-18 06:02:54

Researchers have uncovered a protein that helps some breast cancer tumors to break through their surrounding cell matrix and spread to other tissues. The protein, called hepsin, is a protease which is a class of enzymes that cuts other proteins. Proteases can be successfully targeted by drugs, providing the opportunity to target hepsin as a possible new treatment. Co-author Zena Werb, PhD, a professor of anatomy at University of California - San Francisco, said “If we could delay...

Study finds perinatal exposure to BPA has effect on mammary hormone response A recent study accepted for publication in Molecular Endocrinology, a journal of The Endocrine Society, found that perinatal exposure to environmentally relevant doses of bisphenol A (BPA) alters long-term hormone response and breast development in mice that may increase the propensity to develop cancer. BPA, a man-made chemical produced and marketed largely for specific industrial purposes, is detected in body...

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...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
