US faces shortage of donated blood

A person is in need of a blood donation every two seconds in the United States, according to statistics from America's Blood Centers, a network of non-profit community blood centers across the country. Because there is no known substitute for human blood, and it cannot be artificially manufactured, the entire process relies on generous donations from people willing to give. Unfortunately, there is currently a shortage of donated blood across the country.

Defects in mitochondria lead to devastating neurodegenerative disease

A devastating neurodegenerative disease that first appears in toddlers just as they are beginning to walk has been traced to defects in mitochondria, the 'batteries' or energy-producing power plants of cells. This finding by a team of researchers, led by investigators from the Montreal Neurological Institute and Hospital - The Neuro- at McGill University, was published in this week's issue of the Proceedings of the National Academy of Sciences of the USA.

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.

Bioengineers receive $2 million NIH grant to develop new toxicology tests

Chemicals in pharmaceutical drugs can obviously save lives. But as more and stronger chemicals have been introduced, our basic knowledge of the broader health impact of all these chemicals has not kept up with the rapid pace of innovation. There is exceptionally little information on how chemicals in our drugs and also in the environment around us, including on the food we eat, impact some of the most important cells in our body: stem cells. Without basic knowledge and tests on the impact of chemicals on our stem cells, we may be unwittingly damaging essential regenerative functions in our body.

Scientists use gold-filled silicon wafers to target and burn breast cancer cells

By shining infrared light on specially designed, gold-filled silicon wafers, scientists at The Methodist Hospital Research Institute have successfully targeted and burned breast cancer cells. If the technology is shown to work in human clinical trials, it could provide patients a non-invasive alternative to surgical ablation, and could be used in conjunction with traditional cancer treatments, such as chemotherapy, to make those treatments more effective.

Neuronal energy deficits may contribute to amyotrophic lateral sclerosis

Turning off a protein that helps cells balance energy increases animal mobility and reduces the death of nerve cells that control movement in animal models of amyotrophic lateral sclerosis (ALS), according to a study in the January 18 issue of The Journal of Neuroscience. The findings may one day guide new directions for the treatment of the progressive neurodegenerative disorder, for which there is currently no cure.

Study shows how to stop brain cancer cell proliferation and migration

Brain cancer is hard to treat: it's not only strong enough to resist most chemotherapies, but also nimble enough to migrate away from radiation or surgery to regrow elsewhere. New research at the University of Colorado Cancer Center shows how to stop both.

Innovative computer algorithm identifies clinically prognostic marker for cancer

Researchers at the Stanford University School of Medicine have used an innovative mathematical technique to find markers that effectively predict how deadly a cancer will be. The discovery, which in this case concerned bladder cancer, could lead to faster, less expensive and more accurate analysis of cancer risk and better treatment of the disease.

Research reports on effectiveness of Scriptaid in breast cancer cell lines

Although endocrine therapy for breast cancer has shown excellent results in controlling the disease, responsiveness to the therapy depends on whether or not there is expression of estrogen receptors in breast cancer cells. Research from the Sbarro Institute for Cancer Research and Molecular Medicine, a nonprofit cancer, cardiovascular and diabetes research center located in Philadelphia, PA, reports on the effectiveness of a new molecule, Scriptaid, that restores receptivity to endocrine therapy in breast cancer cell lines that had tested negative for the expression of estrogen receptors.

Study compares adoptive T-cell therapy with drug-based cancer treatment

In the treatment of large tumors, how effective is adoptive T cell therapy in comparison to drug-based cancer treatment? To answer this question, Dr. Kathleen Anders and Professor Thomas Blankenstein of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch and researchers of the Beckman Research Institute of the City of Hope Cancer Center in Duarte, California, USA designed and carried out a study comparing the two methods. Based on a mouse cancer model, the researchers elucidated the mechanisms of the two different treatments.

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.
