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.

RNA interference can be used to silence genes selectively - potential for Huntington's disease therapy

Howard Hughes Medical Institute researchers have designed tiny RNA molecules that shut off the gene that causes Huntington's disease without damaging that gene's healthy counterpart, which maintains the health and vitality of neurons.

Discovery of key decision-point at which cells with broken DNA repair themselves or die

When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis.

Researchers explain process by which cells 'hide' potentially dangerous DNA segments

The DNA in the 23 pairs of chromosomes in each of the billions of cells of the human body is so tightly packed that it would measure six feet in length if stretched end to end.

Too much dietary protein and fat may lead to insulin resistance

A clue about the blood chemistry of obese people who develop insulin resistance, a precursor to diabetes, has been confirmed in animal studies at the Duke University Medical Center.

Scientists first evidence of cell-to-cell communication by amino acids

A team of researchers from the Massachusetts General Hospital Center for Engineering in Medicine (MGH-CEM) has found the first evidence of cell-to-cell communication by amino acids, the building blocks of proteins, rather than by known protein signaling agents such as growth factors or cytokines.

New HIV drug may help patients not responding to treatment

A potential treatment for HIV may one day help people who are not responding to Anti-Retroviral Therapy, suggests new research published tomorrow in The Journal of Immunology.

Research reveals new options for people with phenylketonuria

For people with the genetic condition known as phenylketonuria (PKU), diet is a constant struggle.

Hundreds of published studies on natural selection may have drawn incorrect conclusions

Scientists at Penn State and the National Institute of Genetics in Japan have demonstrated that several statistical methods commonly used by biologists to detect natural selection at the molecular level tend to produce incorrect results.

BioMarin receives notice of allowance for Kuvan patent

BioMarin Pharmaceutical Inc. has announced that it has received a notice from the United States Patent Office reporting allowance of claims covering once daily dosing methods for Kuvan (sapropterin dihydrochloride) in the treatment of phenylketonuria (PKU).

Researchers find direct link between oxidative stress and inflammatory signals in the blood

The finding could lead to improved strategies for preventing several diseases by including antioxidants in the diet and for reducing the impact of inflammation in critically ill patients by adding cysteine to intravenous or tube feeding.

RegeneRx reports phase II venous stasis trial results

Regenerx Biopharmaceuticals Inc. has announced the results of its Phase II clinical trial evaluating the safety and wound-healing efficacy of RGN-137 for the treatment of patients with venous stasis ulcers.

New approach to prostate cancer detection - Sarcosine may distinguish between slow-growing and aggressive prostate cancers

On Friday 20 March, US researcher Dr. Chris Beecher from the University of Michigan gave a well attended lecture about sarcosine, an N-methyl derivative of the amino acid glycine, at the 24th Annual EAU Congress in Stockholm, Sweden.

25 Mar 2009

Scientists make a new protein from scratch

No doubt proteins are complex. Most are "large" and full of interdependent branches, pockets and bends in their final folded structure.

Molecular fingerprints point the way to earlier cancer diagnosis and more targeted treatment

Metabolites are molecular fingerprints of what your cells are up to and Dr. Arun Sreekumar wants to know the impression made by cancer.

Tiny genetic change keeps nicotine from binding to muscle cells

A tiny genetic mutation is the key to understanding why nicotine--which binds to brain receptors with such addictive potency--is virtually powerless in muscle cells that are studded with the same type of receptor.

23 Mar 2009

Cells get two chances, not just one, to fix their mistakes

Cells have two chances to fix the same mistake in their protein-making process instead of just one - a so-called proofreading step - that had previously been identified, according to new research.

Long-term effects of two common drugs for early Parkinson's similar

A study published online in the Archives of Neurology involving two common drugs used to treat early-stage Parkinson's disease shows that, while the drugs each have advantages and disadvantages, the overall impact tends to even out over a long period of treatment.

10 Mar 2009

Pulmonary hypertension in children may result from reduced activity of gene regulator

Too little activity by gene regulators called PPARs appears to be a major player in the irreversible lung damage that can occur in children with heart defects, researchers say.

5 Mar 2009

Antibody key to treating variant CJD

Scientists at the University of Liverpool have determined the atomic structure of the 'binding' between a brain protein and an antibody that could be key to treating patients with diseases such as variant CJD.

4 Mar 2009

New protein identified in bacterial arsenal

Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells' normal activities but ultimately co-opting them to serve the bacteria's needs.
