Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

Many receptor models used in drug design may not be useful after all

It may very well be that models used for the design of new drugs have to be regarded as impractical. This is the sobering though important conclusion of the work of two Leiden University scientists published in Science this week.

Discovery of important fat precursor cell

To understand where fat comes from, you have to start with a skinny mouse. By using such a creature, and observing the growth of fat after injections of different kinds of immature cells, Rockefeller University scientists have discovered an important fat precursor cell that may in time explain how changes in the numbers of fat cells might increase and lead to obesity.

Sea birds' DNA may hold keys to aging and cancer, Bucknell researcher says

Chances are, a mouse in the wild will live less than a year before stumbling upon a hungry falcon or feline.

Eli Lilly starts second global phase III trial of investigational Alzheimer's disease compound

Eli Lilly and Company today announced it will begin enrolling patients in a second Phase III study of LY450139, a gamma-secretase inhibitor being investigated as a potential treatment to delay the progression of mild to moderate Alzheimer's disease.

Exelixis files investigational new drug application for anticancer compound

Exelixis, Inc. announced today that it has submitted an investigational new drug (IND) application to the U.S. Food and Drug Administration for XL888, a novel anticancer compound. XL888 is an orally available small molecule inhibitor of HSP90, which is a chaperone protein that promotes the activity and stability of a range of key regulatory proteins, including kinases.

A DNA-based vaccine shows promise against avian flu

Though it has fallen from the headlines, a global pandemic caused by bird flu still has the United States' Centers for Disease Control and Prevention on high alert. Yet, to date, the only vaccines that have proven even semi-effective are produced in chicken eggs, take five to six months to prepare and act against a single variant of the H5N1 virus, which mutates incredibly quickly.

Immune system hurts as well as fights cancer - discovery could lead to new cancer treatments with fewer side effects

Researchers at the University of Pennsylvania School of Medicine have found that some proteins of the immune system can promote tumor growth.

Multiple sclerosis patients have higher spinal fluid levels of suspicious immune molecule

A protein that helps keep immune cells quiet is more abundant in the spinal fluid of patients with multiple sclerosis (MS), further boosting suspicion that the protein, TREM-2, may be an important contributor to the disease.

No blood needed thanks to non-invasive blood monitoring device

A non-invasive blood monitoring device that removes the need to draw blood to monitor patients has won the 2008 Kerrin Rennie Award for Excellence in Medical Technology. The award was presented to Masimo Corporation on 24 September at the Medical Technology Association of Australia (MTAA) dinner in Sydney.

New way to control protein activity could lead to cancer therapies

Investigators at the Stanford University School of Medicine have found a way to quickly and reversibly fine-tune the activity of individual proteins in cells and living mammals, providing a powerful new laboratory tool for identifying - more precisely than ever before - the functions of different proteins.

Hybrid nanoparticles image and treat tumors

By combining a magnetic nanoparticle, a fluorescent quantum dot, and an anticancer drug within a lipid-based nanoparticle, a multi-institutional research team headed by members of the National Cancer Institute's (NCI) Alliance for Nanotechnology in Cancer has created a single agent that can image and treat tumors. In addition, this new nanoparticle is able to avoid detection by the immune system, enabling the particle to remain in the body for extended periods of time.

Targeted nanoparticles map tumor blood supply in 3-D, assess therapy

One of the defining characteristics of solid tumors is the development of a network of new blood vessels to nourish the rapidly reproducing malignant cells. Now, using a nanoparticle targeted to those new blood vessels, a joint academic-industrial research team, led by investigators from the Siteman Center of Cancer Nanotechnology Excellence, has developed a way to construct a three-dimensional (3-D) map of tumor-induced angiogenesis and monitor the effects of drug therapies on those new blood vessels.

Nanotubes detect tumors and deliver high-potency punch

Researchers at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (CCNE-TR), based at Stanford University, have found a new way to target cancer cells while leaving healthy cells untouched.

New pig model of cystic fibrosis provides better understanding of human disease

For the first time, researchers have developed a genetically altered animal model for cystic fibrosis (CF) that closely matches the characteristics of the disease in humans. By studying the complex and multi-organ disease process in the pig model, researchers can now better understand how the complications of CF develop, an advancement that may lead to new avenues for research in prevention and treatment.
