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.

Jumping genes help explain immune system's remarkable ability

A team led by Johns Hopkins scientists has found the first clear evidence that the process behind the human immune system's remarkable ability to recognize and respond to a million different proteins might have originated from a family of genes whose only apparent function is to jump around in genetic material.

Turning off cell suicide switch fails to stop prion damage

Researchers knew that prions, the misfolded proteins that cause mad cow disease and other brain disorders, were killing off a class of important brain cells in a transgenic mouse model. But when they found a way to rescue those cells, they were astonished to discover the mice still became sick.

New DNA sequence translation device

Chemists at New York University have developed a device that allows for the translation of DNA sequences, thereby serving as a factory for assembling the building blocks of new materials.

Major step forward in using saliva to detect oral cancer

Scientists funded by the National Institute of Dental and Craniofacial Research reported taking a major step forward in using saliva to detect oral cancer.

Cancer drug paclitaxel may reduce the adverse effects of Alzheimer's disease

In a preclinical efficacy trial, the cancer drug paclitaxel (Paxceed)–which exerts its effects by binding to and stabilizing microtubules inside cells–reduced the adverse effects of Alzheimer's disease (AD)-like pathology in a mouse model.

Tercica files for patent infringement

Tercica announced today the filing of a suit for patent infringement in the High Court of Justice (Chancery Division Patents Court) in the United Kingdom against Insmed Incorporated of Glen Allen, Virginia and Avecia Limited of the United Kingdom.

Blocking gene's activity may control deadly skin cancer without harming normal cells

Researchers at Dana-Farber Cancer Institute and Children's Hospital Boston have discovered that malignant melanoma, the potentially lethal skin cancer, can't grow without a steady supply of a protein that normal cells can do without.

Blocking a key molecule protects breast implants, permanent catheters, pacemakers and artificial joints from rejection and damage by the body

Blocking a key molecule protects breast implants, permanent catheters, pacemakers, artificial joints, glucose sensors for diabetics, and other biomaterials from rejection and damage by the body, according to a study published this month in The American Journal of Pathology.

Cherries could help lower blood sugar levels in people with diabetes

Perhaps George Washington wouldn't have chopped down his father's cherry tree if he knew what chemists now know. They have identified a group of naturally occurring chemicals abundant in cherries that could help lower blood sugar levels in people with diabetes.

DLX5 gene may play a role in the pathology of Rett Syndrome

A research team led by Terumi Kohwi-Shigematsu of the Life Sciences Division of Lawrence Berkeley National Laboratory has identified a gene, DLX5, that may play a role in the pathology of Rett Syndrome, a devastating neurological disorder diagnosed almost exclusively in girls.

Timing of radiation and antiangiogenic therapy impacts treatment effectiveness

Agents designed to attack blood vessels that feed a growing tumor are effective against tumor growth in laboratory experiments. However, results of early clinical trials with these inhibitors have not yet exhibited the same success observed in animal models.

Messenger RNA not only are measurable in saliva but can indicate a developing tumor

Scientists funded by the National Institute of Dental and Craniofacial Research reported today taking a major step forward in using saliva to detect oral cancer.

Stem cells use inflammatory signals to find injured tissue

A joint effort led by stem cell biologist Evan Y. Snyder, M.D., Ph.D., of The Burnham Institute, and Samia J. Khoury, M.D., of Harvard Medical School and Brigham and Women’s Hospital, report data suggesting that stem cells use inflammatory signals to “know” where they must home.

Researchers discover clues to cirrhosis

Researchers at the University of Essex have found new biochemical indicators of cirrhosis in blood plasma which could help detect the disease in its early stages.

Vaccine against cervical cancer

Dutch researcher Laura Bungener has developed a vaccine against cervical cancer. Vaccinated laboratory animals no longer developed the disease and animals which had already developed a tumour, could be treated with the vaccine.

Macugen approved for the treatment of neovascular (wet) age-related macular degeneration (AMD)

Eyetech Pharmaceuticals and Pfizer have announced that the U.S. Food and Drug Administration (FDA) approved Macugen (pegaptanib sodium injection) for the treatment of neovascular (wet) age-related macular degeneration (AMD), an eye disease associated with aging that destroys central vision.

Rett Syndrome, the first identified epigenetic disease - linked to specific defects in the three-dimensional folding of chromatin

Sometime between the age of 6 and 18 months, after a period of seemingly normal development, girls affected with Rett Syndrome lose interest in play; they gradually become withdrawn and anxious, develop autistic-like behaviors, and acquire specific symptoms like repetitive teeth-grinding and hand-wringing.
