Researchers tap modified plant viruses to ward off cervical cancer-causing infections

New vaccinations to prevent infections that lead to cervical cancer and targeted therapeutics aimed at breast cancer were examples of research highlights presented by scientists today at the 95th Annual Meeting of the American Association for Cancer Research. Scientists described advances that feed into the drug development 'pipeline,' and show strong promise for controlling existing tumors or addressing the pathogen that causes tumors.

p53 protein peptide stops cancer in its tracks

Researchers have dreamed of thwarting cancer by using proteins that halt cell growth and kill the tumor. In theory, the approach should work. In practice, however, scientists have not had an easy time of getting tumor suppressor proteins into cells where they can block growth effectively.

A common antibiotic used to treat arthritis and acne shows promise for limiting the severity of spinal cord and brain injuries

When a fall, car crash, bullet, or knife crushes or cuts a spinal cord, the injury does not stop there. Rather, tissues continue to discharge toxic chemicals for hours, even days and weeks. These chemicals kill and disable nerve cells some distance away from the core injury, compounding the damage and making rehabilitation more difficult or impossible.

Lupus Discovery May Lead To Improved Drugs

In an important development in the treatment of lupus as well as certain cancers, scientists at the Feinberg School of Medicine at Northwestern University have discovered how autoimmune lupus T cells stave off programmed cell death and drive production of autoantibodies directed against the body’s own DNA.

Treatment for ovarian cancer by gene targeting

Targeting and inactivating a key gene could be a subtle and effective treatment for certain types of ovarian cancer, Scottish researchers suggest in a study published in Clinical Cancer Research.

New treatment for heart attacks

A team led by scientists at The Scripps Research Institute has developed a potential new treatment for heart attacks. The therapy inhibits fluid leakage from cardiac blood vessels following a heart attack and thereby significantly prevents long-term heart damage and improves survival.

Cigarette Smoking May Lower Rates of Neurodegenerative Diseases like Parkinson's and Alzheimer's

While the health risks of tobacco are well known, several studies have shown that people with a history of cigarette smoking have lower rates of neurodegenerative diseases like Parkinson's and Alzheimer's disease. However, the explanations for nicotine's neuroprotective effects continue to be debated.
