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

Caspase-8 protein plays an important role in proliferation and invasion of cancer cells

Scientists at Burnham Institute for Medical Research have found that the Caspase-8 protein, long known to play a major role in promoting programmed cell death (apoptosis), helps relay signals that can cause cancer cells to proliferate, migrate and invade surrounding tissues. The study was published in the journal Cancer Research on June 15.

Research suggests core nuclear pore elements shared by all eukaryotes

For perhaps 1.8 billion years after life first emerged on Earth, a sort of evolutionary writer's block stalled the development of organisms more complicated than single cells. Then, a burst of experimental creativity about 1.7 billion years ago brought the cell nucleus onto the scene, stashing the cell's genetic material inside a protective inner membrane and setting the stage for the evolution of more sophisticated creatures from yeast, say, to plants and human beings.

Research may hold key to maintaining embryonic stem cells in lab

In a new study that could transform embryonic stem cell (ES cell) research, scientists at UT Southwestern Medical Center have discovered why mouse ES cells can be easily grown in a laboratory while other mammalian ES cells are difficult, if not impossible, to maintain.

Shire files treatment protocol for Velaglucerase Alfa for Gaucher’s disease

Shire plc has announced that, at the request of the FDA, in view of a potential restriction on the availability of the current approved and marketed treatment for Gaucher’s disease patients, it has filed a treatment protocol for velaglucerase alfa, its enzyme replacement therapy in development for the treatment of Gaucher’s disease.

Glutamic acid linked to lower blood pressure

Glutamic acid may be one of the components responsible for the lower blood pressures of people with vegetable-rich diets, according to a study published today in Circulation: Journal of the American Heart Association. Glutamic acid is a major component of protein; vegetable protein contains higher levels of glutamic acid than animal protein.

Research pinpoints antibodies that may prevent Alzheimer's

Antibodies to a wide range of substances that can aggregate to form plaques, such as those found in Alzheimer's patients, have been identified in the blood and cerebrospinal fluid of healthy people. Levels of these antibodies decline with age and, in Alzheimer's patients, with increasing progression of the disease.

Amino acid commonly found in vegetable protein may lower blood pressure

Consuming an amino acid commonly found in vegetable protein may be associated with lower blood pressure, researchers report in Circulation: Journal of the American Heart Association.

Breakthrough in combating adverse side-effects associated with quinine

Discovered back in the 1600s quinine was the first effective treatment in the fight against malaria - and it continues to be a commonly used treatment against this devastating disease. But the drug is associated with a long list of side effects which can range from sickness and headaches to blindness, deafness and in rare cases death - and until now no one knew why.

Enzyme TFIIH kinase found to be involved in epigenetic regulation

For many years scientists have known that the numerous biological functions of an organism are not regulated solely by the DNA sequence of its genes: Superordinate regulatory mechanisms exist that contribute to determining the fate of genes. Although they are not anchored in the DNA, they can even be passed on to subsequent generations to a certain extent. Intensive research in recent years has shown that these mechanisms - bundled under the term epigenetics, are very multifaceted and complex.

Genomic discovery: Protecting kidney function during heart failure

Mayo Clinic cardiology researchers have found a peptide that helps preserve and improve kidney function during heart failure, without affecting blood pressure. Earlier variations of this peptide caused blood pressure to drop limiting the potential benefits to the kidneys. The findings appear in the current Proceedings of the National Academy of Sciences.

Marker in blood may explain susceptibility to interstitial cystitis

A marker in the blood of both cats and humans that was identified in a recent study might signal both species' susceptibility for a painful bladder disorder called interstitial cystitis, a condition that is often difficult to diagnose.

Scientists create simple chemical system that mimics DNA

A team of Scripps Research scientists has created a new analog to DNA that assembles and disassembles itself without the need for enzymes. Because the new system comprises components that might reasonably be expected in a primordial world, the new chemical system could answer questions about how life could emerge.

Structure of the HIV protein shell revealed

New research by scientists at The Scripps Research Institute and other institutions provides a close-up look at the cone-shaped shell that is the hallmark of human immunodeficiency virus (HIV), revealing how it is held together - and possible ways to break it apart.

Newly discovered peptide promises hope for Alzheimer's disease

Researchers in Japan have detected a peptide in cerebrospinal fluid (CSF) that can show whether a person is developing Alzheimer's disease. Measuring the level of this peptide could show that the disease process has started, long before any serious damage is done to the brain.

Novel approach for treating cognitive impairments

Researchers have been seeking a safe and effective way to treat cognitive impairments associated with schizophrenia by enhancing N-methyl-D-aspartate (NMDA) glutamate receptors. Functional deficits in NMDA receptors may contribute to the underlying neurobiology of this disorder.

Drug derived from the hydrangea root shows promise for autoimmune disorders

A drug derived from the hydrangea root, used for centuries in traditional Chinese medicine, shows promise in treating autoimmune disorders, report researchers from the Program in Cellular and Molecular Medicine and the Immune Disease Institute at Children's Hospital Boston (PCMM/IDI), along with the Harvard School of Dental Medicine.

Skin cells provide new knowledge about brain functions

Until now diseases like schizophrenia and bipolar disorder have been difficult to study biologically, since this would entail taking samples from the patient's brain.

Smoking and genetics play role in rheumatoid arthritis

Recent genetic studies have revealed several new sites of genes that are risk factors for developing rheumatoid arthritis (RA).

“Misreading” of histone code linked to human cancer

The development of blood from stem cell to fully formed blood cell follows a genetically determined program. When it works properly, blood formation stops when it reaches maturity. But when it doesn't, genetic mutations can prevent the stop signal and cause the developing cells to turn cancerous. In research published in Nature, Rockefeller University scientists show for the first time that a misreading of the blood cells' histone code is responsible for acute myeloid leukemia, a rare form of the deadly blood cancer.

Extreme caffeinated soft drink diet leaves woman with serious health issues

Reports in the media of a New Zealand woman's extreme Red Bull diet where her weight plummeted from 105kg to 60kg by drinking 10 to 14 cans of the 'energy' drink each day say she has been left with serious health issues.
