Protein called cyclin D1 disrupts BRCA1's normal role as a cancer inhibitor

For about a decade, scientists have recognized that many cases of hereditary breast cancer result from a mutation of a specific gene called BRCA1, which, in its normal state, helps keep tumor formation in check. About five to 10 percent of breast cancer cases are linked to genetic miscues, about half of which are linked to BRCA1.

Cancer cells may be able to avoid destruction by anti-vascular and anti-angiogenesis agents

Cancer cells may be able to avoid destruction by anti-vascular and anti-angiogenesis agents through a cellular stress response that activates a pro-survival protein called GRP78, according to researchers from the Keck School of Medicine of the University of Southern California.

Test accurately predicts aggressiveness of breast cancer

A test that measures how quickly cells are dividing is an accurate way for doctors to predict the aggressiveness of breast cancer tumors, even among women with very early stages of the disease, researchers told the 2nd ESMO Scientific & Educational Conference (ESEC) in Budapest, Hungary.

New approach to inhibiting blood vessel growth or angiogenesis

A manmade protein with a tail of amino acids delivered to target cells can dramatically reduce blood vessel growth that obstructs vision or feeds a tumor, researchers have found.

Ibuprofen use is associated with an increased risk of breast cancer

Ibuprofen use is associated with an increased risk of breast cancer, and long-term daily use of aspirin is associated with an increased risk of estrogen receptor/progesterone receptor (ER/PR)-negative breast cancer, according to a new study in the June 1 issue of the Journal of the National Cancer Institute.

Don’t skip chest CT in the ER just because X-ray checks out okay, warns study

Chest X-rays may miss 40% of clinically significant thoracic injuries in multiple trauma patients that can be caught by chest CT, say researchers from Massachusetts General Hospital in Boston.

New drug combination prevents breast cancer growth pre-surgery

A new type of drug originally developed for lung cancer can reduce the size of breast cancer tumours when taken in combination with other drugs.

Zometa reduces bone loss in patients receiving breast cancer treatment

Data presented at the American Society of Clinical Oncology (ASCO) annual meeting in Orlando, Florida, demonstrate that Zometa (zoledronic acid), an intravenous bisphosphonate, was shown to inhibit bone loss in postmenopausal women treated with Femara (letrozole) in the adjuvant breast cancer setting (directly following surgery to prevent cancer recurrence).

75,000 children end up in hospital emergency rooms due to trampoline injuries

Linakis states quite categorically that the home environment and even the school environment are not the place for trampolines. He says though it will not be a popular idea, trampolines are only appropriate in very select, heavily supervised environments, such as a gymnastics school.

Millions of employed Americans uninsured and unable to get Medical Care

A new study analyzing data from the Centers for Disease Control and Prevention shows that a significant number of working Americans in every state do not have health care coverage, with more than 20 million working adults not having coverage. In eight states, at least one in five working adults is uninsured.

P12 protein influences key cell-signaling pathway

New research shows that a protein produced by a cancer-causing virus influences a key signaling pathway in the immune cells that the virus infects. This stimulates the cells to divide, helping the virus spread through the body.

Scientists have, for the first time, induced a state of reversible metabolic hibernation in mice

Scientists at Fred Hutchinson Cancer Research Center have, for the first time, induced a state of reversible metabolic hibernation in mice. This achievement, the first demonstration of "hibernation on demand" in a mammal, ultimately could lead to new ways to treat cancer and prevent injury and death from insufficient blood supply to organs and tissues.

To boost efficiency, hospitals borrow principles from factory floor

Many health-care industry bottlenecks can be eliminated, resulting in major improvements in efficiency, cost savings and patient care when hospitals borrow principles from production lines on the factory floor, according to researchers in the School of Engineering and Applied Sciences at the University at Buffalo.

Why different tissues in the human body vary in their susceptibility to "amyloid" diseases

Researchers at The Scripps Research Institute are reporting the results of a recent study that addresses why different tissues in the human body vary in their susceptibility to "amyloid" diseases, which include Alzheimer's disease and a cluster of ailments called the familial amyloidoses.

Relief for overactive bladder patients

New landmark data (the STAR Study), revealed today from the European Association of Urology in Istanbul, Turkey, show that patients suffering from Overactive Bladder (OAB) syndrome will see considerably better improvements in their symptoms when being treated with the new antimuscarinic drug solifenacin, than on tolterodine ER - an antimuscarinic drug that is widely used.

New twist on the role that estrogens play in the development of behavioral differences between men and women

What makes a man behave like a man and a woman a woman? The answer may be partly in your genes. Researchers at the University of Virginia Health System have discovered a new twist on the role that estrogens play in the development of behavioral differences between males and females.

Scientists have identified a key network that prevents damage by oxygen radicals

Reactive oxygen species (ROS), or 'oxygen radicals', have been identified as major contributors to signs of premature aging, increased cancer prevalence linked to inflammation-associated syndromes and a variety of human diseases.

Blocking estrogen may be vitally important to improving survival from lung cancer

New and effective treatments for lung cancer may rest on their ability to hinder the action of estrogen in lung cancer cells, according to two studies published in the current issue of Cancer Research.

Why estrogenic hormones produce unintended results in women

New research is shedding light on why estrogenic hormones produce unintended results in women, giving hope to the idea that new drugs might reach their targets and work more effectively. Ultimately it could mean that postmenopausal women would know that hormone-replacement therapy would have only its intended result.

Clinical trials to test the safety of a first-of-its-kind human hookworm vaccine

Clinical trials to test the safety of a first-of-its-kind human hookworm vaccine will begin in the Washington, DC area in a couple of months after the U.S. Food and Drug Administration conferred investigational new drug status on the vaccine.
