A powerful new breast cancer treatment could result from packaging one of the newer drugs that inhibits cancer's hallmark wild growth with another that blocks a primordial survival technique in which the cancer cell eats part of itself, researchers say. While they are powerful killers of some breast cancer cells, new drugs called histone deacetylase inhibitors, or HDAC inhibitors, also increase self-digestion, or autophagy, in surviving, mega-stressed cells, Medical College of Georgia Cancer...

Results of transgenic mouse study directly applicable to human breast cancer tumor study Sanford Barsky, M.D., who holds faculty positions at the University of Nevada School of Medicine as chair of the pathology department and Nevada Cancer Institute chief of pathology, is part of a team that has a paper on transgenic mouse mammary tumors with direct relevance to human breast cancer published in the October 22 issue of the scientific journal Nature. The article, "Pten in stromal fibroblasts...

Researchers at The Wistar Institute have identified a key gene (KLF17) involved in the spread of breast cancer throughout the body. They also demonstrated that expression of KLF17 together with another gene (Id1) known to regulate breast cancer metastasis accurately predicts whether the disease will spread to the lymph nodes. Previously, the function of KLF17 had been unknown. Deaths of most breast-cancer patients are the result of metastasis, a complex, multi-step, and poorly understood...

Social environment can play an important role in the biology of disease, including breast cancer, and lead to significant differences in health outcome, according to results of a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research. "This study uses an elegant preclinical model and shows that social isolation alters expression of genes important in mammary gland tumor growth," said the journal's Deputy Editor Caryn Lerman, Ph.D. "It further...

Scientists at Michigan State University have found exposure to the hormone progesterone activates genes that trigger inflammation in the mammary gland. This progesterone-induced inflammation may be a key factor in increasing the risk of breast cancer. Progesterone is a naturally occurring steroid hormone and promotes development of the normal mammary gland. Progesterone previously has been identified as a risk factor for breast cancer, and in a study published in the Journal of...

How you eat may be just as important as how much you eat, if mice studies are any clue. Cancer researchers have long studied the impact of diet on breast cancer, but results to date have been mixed. New studies show that intermittent calorie restriction provided greater protection from mammary tumor development than did the same overall degree of restriction implemented in a chronic fashion. Researchers believe the answer may lie in the alteration of hormone levels that occurs with...

 A protein known to be overly active in breast cancer can exist in a form that seems to change the structural composition of mammary tissue, potentially making it more conducive to tumor progression, say researchers from the Lombardi Comprehensive Cancer Center at Georgetown University Medical Center (GUMC).At the annual meeting of the Endocrine Society in Washington, DC, the scientists report that the protein, AIB1 (Amplified in Breast Cancer 1), has a shorter form known as AIB1delta3...

Dioxin exposure during pregnancy can harm fast-changing breast tissue cells and that may cause some women to have trouble breast feeding, U.S. researchers said. Corresponding author B. Paige Lawrence of the University of Rochester Medical Center said dioxins are generated mostly by the incineration of municipal and medical waste, especially certain plastics. Most people are exposed through diet. Dioxins also get into the food supply when air emissions settle on farm fields and where livestock...

 A newly discovered gene known as DEAR1 is mutated in breast cancer and is an independent predictor of local recurrence-free survival in early-onset breast cancer, a research team headed by scientists at The University of Texas M. D. Anderson Cancer Center reports in the journal PLoS Medicine."The correlation with local recurrence is significant because so many young women have recurrences in the breast, and cancers that do recur tend to be more aggressive," said senior author Ann...

A stunning discovery based on epigenetics (the inheritance of propensities acquired in the womb) reveals that consuming choline"”a nutrient found in eggs and other foods"”during pregnancy may significantly affect breast cancer outcomes for a mother's offspring. This finding by a team of biologists at Boston University is the first to link choline consumption during pregnancy to breast cancer. It also is the first to identify possible choline-related genetic changes that affect...

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...
