Drug’s effect on Alzheimer’s may depend on severity of disease

Drug’s effect on Alzheimer’s may depend on severity of disease

A cancer drug that has shown promise against Alzheimer’s disease (AD) in mice and has begun early clinical trials has yielded perplexing results in a novel mouse model of AD that mimics the genetics and pathology of the human disease more closely than any other animal model. The drug, bexarotene, was found to reduce levels of the neurotoxic protein amyloid-beta in experimental mice with late-stage Alzheimer’s but to increase levels during early stages of disease. The finding, by researchers at the University of Illinois at Chicago College of Medicine, was reported July 16 at the Alzheimer’s Association International Conference in Copenhagen by Mary Jo LaDu, who in 2012 developed a transgenic mouse that is now regarded as the best animal model of the human disease.

New assay to spot fake malaria drugs could save thousands of lives

New assay to spot fake malaria drugs could save thousands of lives

Chemists and students in science and engineering at Oregon State University have created a new type of chemical test, or assay, that’s inexpensive, simple, and can tell whether or not one of the primary drugs being used to treat malaria is genuine — an enormous and deadly problem in the developing world. The World Health Organization has estimated that about 200,000 lives a year may be lost due to the use of counterfeit anti-malarial drugs Continue reading

New combination drug controls tumor growth, metastasis in mice

New combination drug controls tumor growth, metastasis in mice

Researchers at UC Davis, University of Massachusetts and Harvard Medical School have created a combination drug that controls both tumor growth and metastasis. By combining a COX-2 inhibitor, similar to Celebrex, and an epoxide hydrolase (sEH) inhibitor, the drug controls angiogenesis (blood vessel formation), limiting a tumor’s ability to grow and spread.

Common heart drug’s link to diabetes uncovered by researchers

Common heart drug’s link to diabetes uncovered by researchers

McMaster University researchers may have found a novel way to suppress the devastating side effect of statins, one of the worlds’ most widely used drugs to lower cholesterol and prevent heart disease. The research team — led by Jonathan Schertzer, assistant professor of Biochemistry and Biomedical Sciences and Canadian Diabetes Association Scholar — discovered one of the pathways that link statins to diabetes. Their findings could lead to the next generation of statins by informing potential combination therapies while taking the drug Continue reading

Drug users switch to heroin because it’s cheap, easy to get

Drug users switch to heroin because it’s cheap, easy to get

A nationwide survey indicates that heroin users are attracted to the drug not only for the “high” but because it is less expensive and easier to get than prescription painkillers. Researchers at Washington University School of Medicine in St. Continue reading

How long should HCV treatment last? Study suggests answers are complex

How long should HCV treatment last? Study suggests answers are complex

As new treatments for hepatitis C virus (HCV) are approved, biomedical scientists are exploring their mechanisms and what they reveal about the virus. An online publication this month in Hepatology is the first to report real-time tracking of viral decay in the liver and blood in 15 patients with HCV Continue reading
