Amino Acid News and Research

RSS

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

UV light improves biosensing by immobilizing antibodies

From detecting pathogens in blood samples to the study of protein synthesis, Quartz Crystal Microbalance (QCM) sensors have many uses in modern biology. In this technique, antibodies anchored to gold electrodes on a piece of quartz crystal act like the "hooks" on the sticky side of a Velcro strap, grabbing molecules of interest as they pass by.

Researchers identify FMRP protein as key player in RNA editing

The most common form of heritable cognitive impairment is Fragile X Syndrome, caused by mutation or malfunction of the FMR1 gene. Loss of FMR1 function is also the most common genetic cause of autism. Understanding how this gene works is vital to finding new treatments to help Fragile X patients and others.

Brain tumour discovery offers drug treatment hope

Australian scientists have played a key role in the identification of a new biochemical mechanism that allows brain tumours to survive and grow, offering hope of new drug treatments for some of the most aggressive tumours.

Scientists identify 16M SNPs that associate with risk of gout, serum uric acid levels

Scientists at deCODE Genetics and academic collaborators from Iceland, Norway, Denmark, the Netherlands and the USA report the discovery of low frequency variants in the human genome that associate with risk of gout, a common inflammatory arthritis, and serum uric acid levels.

Scientists discover new metabolic pathway which makes gliomas more aggressive

A research alliance of Heidelberg University Hospital and the German Cancer Research Center, jointly with colleagues of the Helmholtz Center for Environmental Research in Leipzig, have discovered a new metabolic pathway which makes malignant brain tumors (gliomas) more aggressive and weakens patients' immune systems.

New analyses from Phase III studies of VICTRELIS to be presented at AASLD 2011

Merck, known as MSD outside of the United States and Canada, announced today that several new analyses from Phase III studies of VICTRELIS (boceprevir), the company's first-in-class, oral hepatitis C virus NS3/4A protease inhibitor will be presented at the 62nd Annual Meeting of the American Association for the Study of Liver Diseases.

Researchers discover new inherited disorder that causes mental retardation, liver dysfunction

Researchers at the Swedish medical university Karolinska Institutet have discovered a new inherited disorder that causes severe mental retardation and liver dysfunction. The disease, adenosine kinase deficiency, is caused by mutations in the ADK gene, which codes for the enzyme adenosine kinase.

New targeting approach to develop an active site-directed, drug-like PTP1B inhibitor

The work of a team of scientists at Cold Spring Harbor Laboratory (CSHL) led by Professor Nicholas Tonks FRS, suggests a way to overcome one of the major technical obstacles preventing a leading therapeutic target for diabetes and obesity from being addressed successfully by novel drugs.

Low vitamin B12 raises risk of dementia in the elderly: Study

According to a latest study the elderly with low levels of vitamin B12 in their blood may be more likely to develop problems with their thinking skills and have more brain shrinkage. The study points to a link between low B12 and early cognitive decline, a condition that often leads to dementia. Previous research has found that those people with high levels of vitamin B12 in their blood have lower levels of an amino acid called homocysteine, which some studies have linked to an increased risk of Alzheimer's disease, memory loss, and stroke.

Ambrx, Bristol-Myers Squibb collaborate for novel biologics to treat heart failure and diabetes

Bristol-Myers Squibb Company and Ambrx, Inc. today announced a collaboration under which Bristol-Myers Squibb will receive exclusive worldwide rights to research, develop and commercialize biologics based on Ambrx's research surrounding the Fibroblast Growth Factor 21 protein, for potential use in treating type 2 diabetes, and the Relaxin hormone, for potential use in treating heart failure.

Jefferson experts review most commonly used CAM practices for mood disorders

Mood disorders are among the most prevalent mental health issues today. While medication is available, more and more people are turning to complementary and alternative medicine (CAM), including herbal remedies, acupuncture, and meditation to help manage their mood disorders.

A code beyond DNA: Modified tRNA bases are characteristic of species

Our genetic code consists of four “letters” in the form of the nucleobases in our DNA and RNA. Three letters together form a “word” that are translated into an amino acid by tRNA and combined into proteins. Special markings subdivide the gene into active and inactive regions. A third possible level of information has so far received less attention: the chemical modification of tRNA nucleobases. In the journal Angewandte Chemie Thomas Carell and a team at the University of Munich have now demonstrated that tRNA modification profiles can be used for the characterization of species and the differentiation of pathogenic and nonpathogenic bacterial strains.

Novel therapies remove the brakes cancer puts on the immune system

Some of the newest therapies in the war on cancer remove the brakes cancer puts on the immune system, Georgia Health Sciences University researchers report.

Researchers show how protein fortilin promotes growth of cancer cells

Researchers have shown for the first time that the protein fortilin promotes growth of cancer cells by binding to and rendering inert protein p53, a known tumor suppressor. This finding by researchers at the University of Texas Medical Branch may lead to treatments for a range of cancers and atherosclerosis, which p53 also helps prevent, and appears in the current print issue of the Journal of Biological Chemistry.

UNC-45A protein plays critical role in breast cancer cell division and migration

Researchers have found that a protein linked to cell division and migration and tied to increased cell proliferation in ovarian tumors is also present at high levels in breast cancer specimens and cell lines. The protein, dubbed "UNC-45A," was also determined to be more active in breast cancer cells than in normal breast cells.

CHK Nutrition, NeuroResearch Clinics sign consent to halt sale of unapproved amino-acid products

The U.S. Food and Drug Administration announced that two Minnesota companies have agreed to halt distribution of amino-acid products marketed to treat a number of diseases, until requirements of the Federal Food, Drug, and Cosmetic Act are met.

Human gliomas release excess levels of glutamate and trigger seizures

Glioma, one of the most deadly and common types of brain tumor, is often associated with seizures, but the origins of these seizures and effective treatments for them have been elusive. Now a team funded by the National Institutes of Health has found that human gliomas implanted in mice release excess levels of the brain chemical glutamate, overstimulating neurons near the tumor and triggering seizures.

Robert Gordon University scientists to develop new treatment for cystinosis

A team of researchers at Robert Gordon University has secured a six figure sum from Sparks, a leading children’s medical research charity, to develop a revolutionary treatment for a rare genetic disorder.

Researchers discover new genetic defect that predisposes people to leukemia, myelodysplasia

A new genetic defect that predisposes people to acute myeloid leukemia and myelodysplasia has been discovered. The mutations were found in the GATA2 gene. Among its several regulatory roles, the gene acts as a master control during the transition of primitive blood-forming cells into white blood cells.
