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.

Viewpoints: Health care is a civil right; A Medicare strategy based on Lenin

Martin Luther King Jr.'s legacy is one of progress toward a better life for every American, including equal opportunity in voting, housing, education, and employment. Reflecting on his legacy also means recognizing the steps we must take to address the inequalities that persist. Many of these involve health care. Poor and minority Americans suffer from more preventable diseases on average, lower-quality care, fewer treatment options, and less health insurance coverage.

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.

Ethanol, nonalcoholic compounds in red wine may reduce risk of vascular disease

Observational epidemiologic studies relating wine and alcohol to health all suffer from the fact that they, of necessity, compare people who prefer certain beverages, but not the beverages themselves. While there have been many intervention trials in animals, randomized trials in humans are less common. Randomized crossover trials, in which each subject receives all interventions in sequence, can be especially important as they tend to avoid baseline differences among subjects and can detect effects of different interventions with smaller numbers of subjects.

PCORI to meet this week to release national priorities for medical effectiveness research

The Patient-Centered Outcomes Research Institute, an independent board established by the health law, will meet this week to set priorities for "comparative effectiveness research." In other news related to the health law, the News Hour reports on how the overahul has impacted pediatric cancer patients and the New York Times reports on the law's provisions related to screening kids for obesity and providing them counseling.

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.

Counterfeit, substandard drugs threaten progress in controlling malaria in Africa, researchers report

"Hopes of controlling malaria in Africa could be wrecked by criminals who are circulating counterfeit and substandard drugs, threatening millions of lives, scientists" said in a study published in the Malaria Journal last month, the Guardian reports.

Georgia Tech findings advance glaucoma research

Glaucoma is the second leading cause of blindness. Nearly 4 million Americans have the disorder, which affects 70 million worldwide. There is no cure and no early symptoms. Once vision is lost, it's permanent. New findings at Georgia Tech, published in January during Glaucoma Awareness Month, explore one of the many molecular origins of glaucoma and advance research dedicated to fighting the disease.

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 finds Medicare doesn't pay adequately for clot-busting stroke treatment

Treating stroke patients with clot-busting drugs costs U.S. hospitals substantially more than Medicare pays, a new study finds.

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.

Researchers develop simple process for synthesis of artemisinin

The most effective anti-malaria drug can now be produced inexpensively and in large quantities. This means that it will be possible to provide medication for the 225 million malaria patients in developing countries at an affordable price. Researchers at the Max Planck Institute of Colloids and Interfaces in Potsdam and the Freie Universit-t Berlin have developed a very simple process for the synthesis of artemisinin, the active ingredient that pharmaceutical companies could only obtain from plants up to now.

Regorafenib lengthens lives of patients with metastatic colorectal cancer

An investigational drug called regorafenib slowed the progression of tumors and lengthened the lives of patients with metastatic colorectal cancer, an international phase III clinical trial found. The findings were presented today at the Gastrointestinal Cancers Symposium of the American Society of Clinical Oncology in San Francisco by Mayo Clinic oncologist Axel Grothey, M.D., principal investigator of the trial in the United States.
