Cadmium exposure can cause progression of aggressive breast cancer

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.

Exposure to MEHP shortens reproductive life of female mice

Female mouse fetuses exposed to very high doses of a common industrial chemical that makes plastics more pliable develop significant reproductive alterations and precancerous lesions as they grow up, according to a new toxicology study conducted at Brown University.

New imaging tool reveals subtle changes in breast tissue

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.

Rotational motion plays a critical role in ability of breast cells to form acini

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 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.

Scientists identify pathway that activates hepsin on the surface of breast tumor cells

Scientists from the University of Helsinki and from UCSF have exposed a cell pathway that breast tumor cells use to destruct local tissue neighborhood. Cancer cells may use this pathway to free themselves from mammary epithelial tissue architecture, to spread to surrounding tissues. The cell pathway, the researchers found, is a biochemical chain of events leading to activation of a protein-cleaving enzyme on the surface of the tumor cells.

Scientists identify hepsin protein's role in breast cancer

Cancers rarely are deadly unless they evolve the ability to grow beyond the tissues in which they first arise. Normally, cells -- even early-stage tumor cells -- are tethered to scaffolding that helps to restrain any destructive tendencies. But scientists from the University of Helsinki, Finland, and from UCSF have identified a cleaver-wielding protein that frees some tumor cells, allowing them to further misbehave.

New imaging technology may pinpoint subtle aberrations in molecular biosignature of cancer

Despite advances in both the diagnosis and treatment of breast cancer, the disease remains a leading worldwide health concern.

Tbx3 dysfunction may cause acquired and spontaneous arrhythmias

In a study published in the Dec. 26, 2011, Proceedings of the National Academy of Sciences early edition, researchers led by the University of Utah showed the CCS is extremely sensitive to levels of Tbx3. Mouse embryos with Tbx3 levels below a critical threshold suffered arrhythmia and couldn't survive. As the levels of Tbx3 were increased, mice survived to birth, but as adults they developed arrhythmias or had sudden death.

Researchers discover how normal cells in tumors can drive cancer growth

•A new study published in the journal Nature Cell Biology has discovered how normal cells in tumors can fuel tumor growth.

Study explores critical role of 14-3-3σ in halting breast cancer progression

New research out of McGill University's Goodman Cancer Research Centre provides compelling new evidence that a gene known as 14-3-3σ plays a critical role in halting breast cancer initiation and progression.

HCI researchers discover new way to model human breast cancer

Researchers from Huntsman Cancer Institute (HCI) at the University of Utah have discovered a new way to model human breast cancer that could lead to new tools for predicting which breast cancers will spread and new ways to test drugs that may stop its spread.

Weill Cornell researcher to study link between obesity, inflammation and breast cancer

Funded through Bloomingdale's annual Pink Campaign, The Breast Cancer Research Foundation (BCRF) is awarding a grant to Dr. Andrew J. Dannenberg of Weill Cornell Medical College on Oct. 26 to fund research into the link between obesity, inflammation and breast cancer. Dr. Dannenberg has been a BCRF grantee since 2004.

CSHL publishes 'The Mammary Gland as an Experimental Model' book

Studies of mammary gland biology are essential in the fight against breast cancer. Moreover, the mammary gland represents an excellent model system for investigation of physiological and pathological processes that occur throughout the body.

Perinatal exposure to BPA affects 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 may not affect male testes

Bisphenol A (BPA), a common component of plastic used in many consumer products, has recently become infamous -- and banned in some places -- because it can mimic natural estrogen in the body. A new study by Brown University toxicologists, however, finds that male mice whose mothers were exposed even to high doses of BPA while pregnant developed no signs of harm to their testes as adults.

Flatworms provide new insight into organ regeneration, evolution of mammalian kidneys

Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea-famous for its capacity to regrow complete animals from minuscule flecks of tissue-as an eloquent example, researchers at the Stowers Institute for Medical Research demonstrated how our distant evolutionary cousins regenerate their excretory systems from scratch.

Fatty acids, nutrients during pregnancy can reduce risk of breast cancer in female offspring

Era of Hope conference to feature compelling research examining benefits to daughters During pregnancy, women are counseled to refrain from consuming certain types of foods, beverages and medications in order to avoid jeopardizing the health and development of the fetus.

Researchers demonstrate how Runx3 protein could suppress breast cancer tumor growth

Researchers have identified a protein long known to regulate gene expression as a potent suppressor of breast cancer growth. Their study, in the journal Oncogene, is the first to demonstrate how this protein, known as Runx3, accomplishes this feat.
