Binghamton University researchers investigate evolving malaria resistance

Funded by a $1.5 million grant from the National Institutes of Health, scientists at Binghamton University, State University of New York, hope to understand how the malaria parasite Plasmodium falciparum evolved resistance to the once-effective medication chloroquine.

Researchers unlock mystery of a third olfactory system

Researchers at the University of Maryland School of Medicine have found a "nose within the nose," a unique olfactory system within the noses of mice that is able to "smell" hormones involved in regulating water and salt balance in the body.

Ivermectin is causing genetic selection in river blindness parasite

Ivermectin, the standard drug for treating river blindness (onchocerciasis), is causing genetic changes in the parasite that causes the disease, according to a new study by Roger Prichard (McGill University, Canada) and colleagues, published on August 30, 2007 in the open-access journal PLoS Neglected Tropical Diseases.

Gene regulation in humans is closer than expected to simple organisms

Gene networks are some of the most basic features of a living organism. An external or internal stimulus activates some genes, which in turn control others genes whose activity turns on or off various biological processes (such as the cell cycle, energy production, DNA repair, cellular suicide etc).

1,000 strains of mice that feature the genetic diversity of the world population

Mice that are part of the Collaborative Cross project at Oak Ridge National Laboratory are helping scientists around the world learn more about possible causes of drug abuse, diabetes, sleep disorders, stress and pain, kidney disease and a number of other conditions that affect millions of people.

Researchers discover what makes lymphomas tick

University of Pennsylvania researchers and their colleagues at the Wistar Institute and University of Oxford have discovered the molecular process by which the PAX5 protein, necessary for lymphocyte development, promotes the growth of common lymphomas, thereby unveiling a potential new target in the fight against cancer.

FDA should amend the product information for irinotecan

Not everyone needs a genetic test before taking the cancer drug irinotecan, and the U.S. Food and Drug Administration should modify its prescription guidelines to say so, according to researchers at the University of North Carolina at Chapel Hill.

'Mighty mice' made mightier

The Johns Hopkins scientist who first showed that the absence of the protein myostatin leads to oversized muscles in mice and men has now found a second protein, follistatin, whose overproduction in mice lacking myostatin doubles the muscle-building effect.

Gamma globulin effective treatment for pinkeye

Gamma globulin, a type of antibody isolated from blood samples that used to be routinely given to health care workers and international travelers to protect them from infectious diseases, is a highly effective treatment for pinkeye with little apparent toxicity, according to a study by researchers at the University of Pittsburgh School of Medicine.

St. Jude discovers factors that accelerate resistance to Gleevec targeted therapy in lymphoblastic leukemia

Results of a study by investigators at St. Jude Children's Research Hospital provide strong evidence for why the drug imatinib (Gleevec), which has revolutionized the treatment of chronic myelogenous leukemia (CML), is often unable to prevent relapse of a particularly aggressive form of acute lymphoblastic leukemia (ALL).
