Two proteins that bind to stress hormones work together to maintain a healthy heart in mice, according to scientists at the National Institutes of Health and their collaborators. These proteins, stress hormone receptors known as the glucocorticoid receptor (GR) and mineralocorticoid receptor (MR), act in concert to help support heart health. When the signaling between the two receptors is out of balance, the mice have heart disease.

The work, published April 16 in Science Signaling, may lead to the development of therapeutic compounds that help people with an increased risk of a heart attack.

could be a step toward a treatment to prevent heart attacks

Pathways that Can Repair Brca1 Cancer Gene Mutation Clarified in Mice In a new study in mice, scientists have compensated for mutations in the Brca1 gene that can lead to cancer by deleting a second gene, which then lessens the probability of cancer. Mice Brca1-associated mammary tumors have significant similarities to human BRCA1- associated (BReast CAncer 1, early onset) breast cancer in regard to tumor aggressiveness, high incidence, mutations and genetic instability. The study, led by scientists at National Cancer Institute (NCI), part of the National Institutes of Health, and their colleagues, appeared online April 1, 2010 and in print April 16, 2010, in the journal Cell....
