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

Histidine may be key to new therapies for cardiovascular disease

It's just one little amino acid, but it makes all the difference in protecting the heart from the harmful effects of heart attack and cardiac failure. Researchers from the University of Michigan Medical School suggest this amino acid, called histidine, could be the key to a new therapy for cardiovascular disease

Diet rich in veggies lowers blood pressure

Researchers say that a diet rich in vegetables rather than meat can help to reduce blood pressure, and the more plant protein consumed the better.

Novel way to treat stroke

A joint research effort between researchers at the Burnham Institute for Medical Research in La Jolla, CA, and a team from Japan (Iwate University, Osaka City University, Gifu University, Iwate Medical University) has discovered a novel way to treat stroke and neurodegenerative disorders.

Use of L-arginine following a heart attack provides no benefit

Use of the amino acid supplement L-arginine following a heart attack does not improve certain cardiac functions and measurements and may be associated with an increased risk of death, according to a study in the January 4 issue of JAMA: The Journal of the American Medical Association.

New model for the origin of rheumatoid arthritis

Rheumatoid arthritis (RA) is one of the most common systemic autoimmune diseases, and one of the least understood. Smoking is the major known environmental risk factor for RA, though little is known about the mechanisms involved.

Surprise discovery helps tackle rabies

In an unexpected discovery, scientists at Jefferson Medical College have found that a tiny change in a rabies virus protein can turn a "safe" virus extremely deadly. The finding has enabled the researchers to refine a vaccine they previously created against rabies in wildlife, making it safer and more effective.

Elevated homocysteine levels may be a biomarker for increased risk of AMD

People who have elevated homocysteine in their blood, an amino acid that is a known biomarker for cardiovascular disease, may also be at an increased risk of developing age-related macular degeneration (AMD), according to a study in the January issue of the American Journal of Ophthalmology.

Important skin color gene identified

With help from a common aquarium pet and a recently released online database of human genetic variation, a collaborative team of Penn State researchers has found what could be the most important skin color gene identified to date.

Cancer cell resistance to chemotherapy drugs - mechanism discovered

Technion-Israel Institute of Technology researchers have discovered new mechanisms developed by cancer cells to become resistant to various chemotherapy drugs.

Preventing muscle wasting with a leucine-rich diet

Muscle in adults is constantly being built and broken down. As young adults we keep the two processes in balance, but when we age breakdown starts to win. However, adding the amino acid leucine to the diet of old individuals can set things straight again.

Disruption of normal gene interaction linked to schizophrenia

Disruption of the normal interaction between the genes PRODH and COMT contributes directly to major symptoms of schizophrenia by upsetting the balance of the brain chemicals glutamate and dopamine, according to a group of investigators that includes a scientist now at St. Jude Children's Research Hospital.

Prion protein codon 129 genotype prevalence is altered in primary progressive aphasia

Most people with a rare type of dementia called primary progressive aphasia (PPA) have a specific combination of prion gene variants, a new study shows.

High blood pressure research advances efforts to tailor drugs to individual patients

Having high blood pressure and a particular genetic alteration dramatically increases the risk of heart attack, stroke or death, and may explain why some hypertensive patients fare worse than others - even if they take the same medication, University of Florida researchers announced.

New high-resolution data on intact ribosome

A new, sharper picture of the nano-machine that translates our genetic program into proteins promises to help researchers explain how some types of antibiotics work and could lead to the design of better ones.

Scientists find new mechanism by which brain cells can be damaged during chronic neurodegenerative diseases

Scientists at the University of Rochester Medical Center have targeted a new culprit and method of attack on neurologic functions in diseases such as Alzheimer's and dementia associated with HIV.

Tryptophan metabolites play an important role in the immune system

Tryptophan is the source of Thanksgiving legend and grist for a "Seinfeld" episode, but it's not the chemical that you'd expect to find in Lawrence Steinman's lab.

Cancer Vaccine - Synthetically generated glycopeptides from tumor cells can stimulate the formation of specific antibodies

Tumor cells and healthy somatic cells differ in the structures on their surfaces. In principle, it should thus be possible to develop a vaccine that causes a patient’s immune system to form antibodies that attack and destroy tumor cells while sparing healthy cells.

Protein called CHIP helps untangle protein misfolding in brain disease

Keeping the body and mind healthy depends on keeping cells healthy and functioning. This means that cells need a very robust quality-control system to repair or remove damaged or misshapen proteins. Protein handling is especially important in neurons because damage or death of brain cells causes neurological disease.

Reagent under study as cancer vaccine may also help protect tumors

A bacterial mimic under study as a cancer vaccine because it signals the immune system to attack may also help some tumors hide, researchers have found.

Natural blood sugar level lowering compound could lead to new drugs to treat type 2 diabetes

A carbohydrate isolated from the liver lowers blood sugar levels after it is injected into diabetic rats, according to research carried out by a team of experts at the University of Virginia Health System (UVHS).
