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.

Discovery could lead to new drug targets for heart disease

Mice with glowing green hearts have yielded the latest clue in the search for molecules involved in structural heart disease. Vanderbilt University Medical Center investigators found that blocking the activity of a single protein, called CaM kinase, in the mouse heart protects against the damaging effects of a heart attack.

Discovery of missing enzyme for tuberculosis iron scavenging pathway

Scientists have discovered that a protein that was originally believed to be involved in tuberculosis antibiotic resistance is actually a "missing enzyme" from the biosynthetic pathway for an agent used by the bacteria to scavenge iron.

Newly emerging illness, named staphylococcal purpura fulminans

Researchers at the University of Minnesota have identified a newly emerging illness, named staphylococcal purpura fulminans. The disease begins as a respiratory tract infection, which then is infected by Staphylococcus aureus.

A circadian rhythm gene discovered

A few rare people who consistently nod off early, then wake up wide-eyed much before dawn, can blame a newly-found mutant gene for their sleep troubles, Howard Hughes Medical Institute researchers announced today.

Protein Mnd2 protects chromosome bonds

The protein Mnd2 inhibits premature separation of chromosomes during the formation of gametes. The now published discovery of this regulatory function may help to understand the origin of some common congenital chromosome defects.

Vical Incorporated issued two Canadian patents

Vical Incorporated announced today the issuance of two Canadian patents on the company's core technology, which involves direct administration of polynucleotide genetic material such as DNA or RNA.

Important link between kidney damage and cardiac problems

Scientists have identified an important link between kidney damage and cardiac problems, creating new possibilities for treating the primary cause of death in kidney disease patients.

Herceptin - more powerful treatment for patients with HER-2-positive breast cancer

A new use of the drug Herceptin appears to offer a much more powerful treatment advantage than expected for patients with HER-2-positive breast cancer, say researchers at The University of Texas M. D. Anderson Cancer Center.

Pcsk9 gene - new target for cholesterol-lowering drugs

Mice lacking a key protein involved in cholesterol regulation have low-density lipoprotein, or "bad" cholesterol, levels more than 50 percent lower than normal mice, and researchers suggest that inhibiting the same protein in humans could lead to new cholesterol-lowering drugs.

New prostate cancer test

Tessera, Inc., a Seattle-based biomedical company, has released its first product, ProstaMark EPCA (Early Prostate Cancer Antigen), as an Analyte Specific Reagent (ASR) for commercial use in pathology laboratories to assist pathologists in their efforts to determine if cancer is present in the prostate.

KCP protein protects kidneys from damage caused by chronic renal disease and injury

University of Michigan scientists have identified a new and unusual protein that reduces, in laboratory mice, kidney damage caused by chronic renal disease and acute toxic injuries.

Body fat may promote inflammation

Why does extra fat around the waist increase the risk of heart disease? A new study by Wake Forest University Baptist Medical Center researchers and colleagues suggests that inflammation may be the key.

Vegetarians who don't cook their food have abnormally low bone mass

Vegetarians who don't cook their food have abnormally low bone mass, usually a sign of osteoporosis and increased fracture risk. But a research team at Washington University School of Medicine in St. Louis also found that raw food vegetarians have other biological markers indicating their bones, although light in weight, may be healthy.

Variation in the gene ENPP1 may predict risk for diabetes

A particular gene variant that could serve as a predictor for type 2 diabetes has been identified by researchers at UT Southwestern Medical Center.

Vital molecular step in cell migration

A vital molecular step in cell migration, the movement of cells within the body during growth, tissue repair and the body's immune response to invading pathogens, has been demonstrated by researchers in the University of California, San Diego (UCSD) School of Medicine.

New color-coded test for protein folding

Every protein--from albumin to testosterone--is folded into a unique, three-dimensional shape that allows it to function properly. Now Stanford University scientists have developed a simple test that instantly changes color when a protein molecule attached to a gold nanoparticle folds or unfolds.

Use of DNA-damaging agents revolutionizes chemotherapy against a wide variety of cancers

A new study demonstrates the potential effectiveness of treating tumors by combining agents that damage DNA with a drug that sensitizes cancer cells to these agents.

Test that will prevent the needless loss of the thyroid gland in people with the noncancerous condition

New research suggests that physicians can distinguish between a type of thyroid cancer and an identical-looking, non-cancerous thyroid condition by simply determining the activity of three genes.

New therapy for treating cat allergies looks promising

Andrew Saxon, M.D., and a team of researchers at University of California, Los Angeles (UCLA) have found that a molecule designed to block cat allergies can prevent allergic reactions in laboratory mice and was also successful when tested on human cells in a test tube.

Fish is brain food

Researchers with the Department of Veterans Affairs (VA) and the University of California at Los Angeles (UCLA) found that a diet high in docosahexenoic acid, or DHA--an omega-3 fatty acid found in relatively high concentrations in cold-water fish--dramatically slowed the progression of Alzheimer's disease in mice.
