Amino Acid is one of several molecules that join together to form proteins. There are 20 common amino acids found in proteins.

Scientists closer to a potential vaccine or treatment for botulism

By deciphering the near atomic-level structure of the catalytic domain of botulinum toxin type E — one of seven neurotoxins that cause botulism, a disease that paralyzes victims by blocking nerve cells’ ability to communicate — scientists at the U.S. Department of Energy’s Brookhaven National Laboratory are one step closer to a potential vaccine or treatment.

Developing smart drugs

Dana-Farber Cancer Institute Researchers, sensing an opening in the cancer battle, are mounting a quick thrust to flush out suspected molecular cancer triggers in tumor cells.

New technique of identifying genes may help researchers developing drugs

A quick new technique able to identify genes that evolve rapidly as well as those that change slowly already has pinpointed new targets for researchers developing drugs against tuberculosis and malaria, and it could do the same for other infectious diseases, according to a paper in this week's Nature.

Scientists have unraveled the behavior of one key component of bacteria

The researchers studied a mechanism of action they call the "magic spot" – an important regulator of gene expression. They describe their results in the current issue of the journal Cell.

Researchers make millions upon millions of drug-like peptides quickly and efficiently

Two Johns Hopkins scientists have figured out a simple way to make millions upon millions of drug-like peptides quickly and efficiently, overcoming a major hurdle to creating and screening huge "libraries" of these super-short proteins for use in drug development.

A promising new therapy for rheumatoid arthritis

A promising new therapy for rheumatoid arthritis (RA) developed by researchers at the University of California, San Diego (UCSD) School of Medicine re-educates the body's immune system to prevent an attack against healthy joint tissue.

Black women with high blood pressure during pregnancy have higher homocysteine levels

Black women with pregnancy-induced high blood pressure have more homocysteine (an amino acid linked with atherosclerosis) and less folic acid in their blood than white women.

Protein identification gets a speed boost

But the labor intensity of the procedure is now a thing of the past for researchers in the Oregon Health & Science University School of Medicine. The Proteomics Shared Resource, an unassuming but state-of-the-art lab on the fifth floor of OHSU's Medical Research Building, can process more than three times as many protein samples in half a day, and much of it can be done by one person.

A new technique for engineering protein crystals is helping scientists figure out the three-dimensional structures of some important biological molecules

A new technique for engineering protein crystals is helping scientists figure out the three-dimensional structures of some important biological molecules, including a key plague protein whose structure has eluded researchers until now. The technique, developed with support from the National Institute of General Medical Sciences (NIGMS) of the National Institutes of Health (NIH), promises to help pharmaceutical companies develop more effective drugs to treat various diseases by tailor-making molecules to "fit" a protein's shape.

Compounds that may stop replication of T-cell leukemia virus

Researchers are analyzing several compounds that may inhibit the enzyme that is essential for the reproduction of the Human T-cell Leukemia Virus Type 1 (HTLV-I), which has infected 15 to 20 million people worldwide. The virus causes the fatal adult T-cell leukemia in up to 10 percent of those infected.

Researchers find new purpose for existing drugs to suppress colon cancer metastasis, secure post-radiation brain function, and trick tumors

Drugs approved for treatment of specific maladies sometimes show unexpected benefits. Researchers at the 95th annual meeting of the American Association for Cancer Research demonstrated highlighted how some drugs may one day offer previously unforeseen benefits for patients.

First large-scale clinical trial of chelation therapy, a controversial treatment for heart disease

NYU Medical Center has begun enrolling patients in the first large-scale clinical trial of chelation therapy, a controversial treatment for heart disease widely practiced by complementary and alternative medicine physicians. The new, government-funded nationwide study will determine whether the therapy benefits people with coronary artery disease, the leading cause of death for both men and women in the United States.

A simple dietary supplement may also help to prevent strokes

A simple dietary supplement may not only give relief to some of the more than 400,000 New Zealanders that suffer from the pain of migraine headaches, but may also help to prevent strokes.

p53 protein peptide stops cancer in its tracks

Researchers have dreamed of thwarting cancer by using proteins that halt cell growth and kill the tumor. In theory, the approach should work. In practice, however, scientists have not had an easy time of getting tumor suppressor proteins into cells where they can block growth effectively.

Walnuts prevent heart disease

A new clinical study shows that substituting walnuts for monounsaturated fat in a Mediterranean diet improves, and even restores, endothelial function (the property of arteries to dilate in order to meet an increased demand of blood, for instance due to a physical effort). Walnuts also reduce harmful cell adhesion molecules which are associated with atherosclerosis, commonly known as hardening of the arteries. These dual effects enhance the circulatory system, therefore aiding in the prevention of heart disease.

Design of artificial prion may aid fight against mad cow disease

The culprit behind mad cow disease, a.k.a. bovine spongiform encephalopathy, is the most infamous mammalian form of prions. Prions are misfolded proteins that are capable of growing, replicating, and being passed on to daughter cells, that is, they are by themselves heritable. Beyond their disease manifestation, prions also occur naturally in some organisms (such as yeast) and may play important roles in their growth and development. Now, Osherovich and colleagues have identified the amino acid sequences that allow prions to aggregate and replicate, and thereby pass through generations of cells - and prove this by designing an artificial yeast prion that does not exist in nature.

New Theory About Alzheimer's Disease

A group of scientists at The Scripps Research Institute has proposed a new theory about the cause of Alzheimer's disease, the progressive neurodegenerative disorder that currently afflicts some 4.5 million Americans. According to the hypothesis, the disease arises as a consequence of inflammation, which creates abnormal metabolites out of normal brain molecules.
