AMPK enzyme promotes survival of cancer cells: Research

A molecule thought to limit cell proliferation also helps cancer cells survive during initial tumor formation and when the wayward cells spread to other organs in the body, researchers at the University of Illinois at Chicago College of Medicine have found.

Study unveils crystal structure of H. pylori's acid receptor

University of Oregon scientists have discovered how the bacterium Helicobacter pylori navigates through the acidic stomach, opening up new possibilities to inactivate its disease-causing ability without using current strategies that often fail or are discontinued because of side effects.

Ten young researchers named Pew Latin American Fellows in the Biomedical Sciences

Ten young researchers were named Pew Latin American Fellows in the Biomedical Sciences today by The Pew Charitable Trusts. For these scientists, who have dedicated their careers to finding solutions for some of the world's most troubling health problems, this fellowship will provide support that will further their research, enable them to work with colleagues in the United States, and increase scientific knowledge throughout their home region.

Study investigates how breast cancer cells migrate to bone

Breast cancer cells frequently move from their primary site and invade bone, decreasing a patient's chance of survival. This process of metastasis is complex, and factors both within the breast cancer cells and within the new bone environment play a role. In next week's Journal of Biological Chemistry "Paper of the Week," Roger Gomis and colleagues at the Institute for Research in Biomedicine in Spain investigated how breast cancer cells migrate to bone.

Chagas disease – ‘the AIDS of the Americas’

A recent editorial published in the Public Library of Science's Neglected Tropical Diseases called Chagas disease, a parasite which kills about 20,000 people a year, "the AIDS of the Americas." The disease can be transferred to a child from its mother or by blood transfusions. About 20 percent of those infected can develop life-threatening illness that includes enlarged hearts or intestines, and the drugs used today to treat the disease can take months to work.

ASS234 molecule inhibits aggregation of the Alzheimer's protein

Researchers at Universitat Aut-noma de Barcelona (UAB), the Spanish National Research Council (CSIC) and the University of Barcelona (UB) have developed a multitarget molecule, ASS234, which according to the results of in vitro studies conducted, inhibits the aggregation of the --amyloid protein, involved in Alzheimer's disease.

Engineered proteins demonstrate flu-fighting potency

Computer-designed proteins are under construction to fight the flu. Researchers are demonstrating that proteins found in nature, but that do not normally bind the flu, can be engineered to act as broad-spectrum antiviral agents against a variety of flu virus strains, including H1N1 pandemic influenza.

Glucocorticoid steroids in intelligent medicine specifically hits relevant cells

Scientists at Aarhus University, Denmark in collaboration with the biotech company Cytoguide now publish a key to use glucocorticoid steroids in a kind of intelligent medicine that specifically hits the relevant cells. Data are based on rodent studies but if this principle is translated to humans it may greatly improve todays hazardous treatment with this type of potent steroids.

Molecular structure of APP protein could lead to new therapeutics for AD

The molecular structure of a protein involved in Alzheimer's disease - and the surprising discovery that it binds cholesterol - could lead to new therapeutics for the disease, Vanderbilt University investigators report in the June 1 issue of the journal Science.

IL-6 protein plays a pivotal role in the duration of acute pancreatitis

Scientists from the Universities of Illinois and California have found that the inflammatory protein interleukin-6 (IL-6) plays a pivotal role in the duration of acute pancreatitis in animal models with this condition.

New photoactive compound eradicates 'Iraqibacter' from wounds and skin infections

Researchers at the University of California, Santa Cruz, have developed a novel approach for eradicating drug-resistant bacteria from wounds and skin infections, using light to trigger the controlled release of nitric oxide. The UCSC team developed a photoactive compound that releases nitric oxide when exposed to light, and loaded it into a porous, biocompatible material that could be applied as a sprayable powder.

GPUs simulate molecular processes during swine flu drug treatment

Professor Adrian Mulholland and Dr Christopher Woods from Bristol's School of Chemistry, together with colleagues in Thailand, used graphics processing units (GPUs) to simulate the molecular processes that take place when these drugs are used to treat the H1N1-2009 strain of influenza - commonly known as 'swine flu'.

DFG to establish 20 CRCs by 1 July 2012

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) is to establish 20 Collaborative Research Centres (CRCs) by 1 July 2012. This decision was taken by the Grants Committee at its spring session in Bonn. The new CRCs will receive funding totalling 176 million euros (including a 20 percent programme allowance for indirect project costs) for the initial 4-year funding period.

Secreted vesicles play role in spread of cancer

Cancer researchers have known for well over a century that different tumor types spread only to specific, preferred organs. But no one has been able to determine the mechanisms of organ specific metastasis, the so-called "soil and seed" theory of 1889. New details that could help shed light on this hypothesis have been provided by a team of researchers from Weill Cornell Medical College, Memorial Sloan-Kettering Cancer Center, and their collaborators, proposing a new mechanism controlling cancer metastasis that offers fresh diagnostic and treatment potential.

Neural protein plays two opposing roles

A protein produced by the central nervous system’s support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm.
