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

New analysis method shows how the brain regulates its signals using glutamate

Researchers at Chalmers University of Technology and Gothenburg University in Sweden have achieved something long thought almost impossible - counting the molecules of the neurotransmitter glutamate released when a signal is transferred between two brain cells. With a new analysis method, they showed that the brain regulates its signals using glutamate in more ways than previously realised.

TBI impairs growth hormone production, disrupting cognition, memory and sleep

More than 2.5 million people in the United States alone experience a traumatic brain injury, or TBI, each year. Some of these people are plagued by a seemingly unrelated cascade of health issues for years after their head injury, including fatigue, depression, anxiety, memory issues, and sleep disturbances.

New molecular probe senses the state of proteome in live cells

The folding state of the proteins in live cells often reflect the cell’s general health. Australian scientists have developed a molecular probe that senses the state of the proteome—the entire set of the proteins—by measuring the polarity of the protein environment.

Studying Alzheimer’s and Parkinson’s Disease using Pre-Formed Fibrils

Ariel Louwrier discusses the development of pre-formed tau and alpha-synuclein fibrils for research into Alzheimer's and Parkinson's disease.

Grizzly bears' strategy could help prevent muscle atrophy in humans

Grizzly bears spend many months in hibernation, but their muscles do not suffer from the lack of movement. In the journal "Scientific Reports", a team led by Michael Gotthardt reports on how they manage to do this.

Ancestral-sequence reconstruction of FMO genes unveils structure of important enzyme

To disarm toxic substances, many organisms - including humans - possess enzymes called flavin-containing monooxygenases. Despite their importance, the structure of the enzymes has not been resolved, as the protein is too unstable to study in detail.

NIH awards $1.2 million grant for studying biomolecular interactions to inform better drug design

Biomolecules -- carbohydrates, proteins, nucleic acids, and lipids -- form the foundation of life and are responsible for carrying out every process that occurs in our bodies.

Nanopores – the key to identifying amino acids in proteins

DNA and RNA sequencing has become the new watchword for the biological researchers, as this tells them exactly what is going on at cellular level in health and disease. However, it is a partial revelation unless we also know what is happening at the level of proteins as well.

Edematous severe acute malnutrition linked to DNA modification

A group led by researchers at Baylor College of Medicine has identified significant differences at the epigenetic level - the chemical tags in DNA that help regulate gene expression - between two clinically distinct forms of acute childhood malnutrition known as edematous severe acute malnutrition (ESAM) and non-edematous SAM (NESAM).

Glutamine could help obese people reduce inflammation of fat tissue

Glutamine could help people with obesity reduce inflammation of fat tissue and reduce fat mass, according to a new study at Karolinska Institutet in Sweden and the University of Oxford in the U.K. The researchers also show how glutamine levels can alter gene expression in several different cell types.

Researchers discover new way to supercharge protein production

Medicines such as insulin for diabetes and clotting factors for hemophilia are hard to synthesize in the lab. Such drugs are based on therapeutic proteins, so scientists have engineered bacteria into tiny protein-making factories.

New study improves understanding of widespread diseases

When proteins in the brain form deposits consisting of insoluble aggregates, diseases such as Alzheimer's or Parkinson's can occur. Now a research team has come a step closer to understanding this process.

Human genetics evidence predictive of drug development success, study shows

A new drug candidate is more likely to be approved for use if it targets a gene known to be linked to the disease; a finding that can help pharmaceutical companies to focus their drug development efforts.

Scientists solve 3D structure of vaccinia virus RNA polymerase

For viruses to multiply, they usually need the support of the cells they infect. In many cases, only in their host's nucleus can they find the machines, enzymes and building blocks with which they can multiply their genetic material before infecting other cells.

Ground breaking discovery could lead to new anti TB drugs

New drugs to treat strains of TB which have become resistant to treatment are now a possibility following a ground breaking discovery from the University of Surrey.

New computational method can help predict and design allosteric functions in proteins

Called the "second secret of life", allostery is one of the most fundamental processes of biology and has been a central focus among scientists across the life sciences spectrum, from fundamental biology to drug development.

New compound may enhance dengue vaccine efficacy by simulating amino acid deficiency

A new study published in the journal Science Signaling on November 26, 2019, describes a mouse experiment, in which the immune response to the dengue vaccine was boosted when the mice were first given halofuginone, a plant compound that is well known to herbalists.

Scientists sheds light on small protein and its role in immune response

The immune system is the body’s defense against disease-causing pathogens. It works by warding off disease and potentially-damaging foreign bodies. Now, a team of researchers have developed a new method to shed light on the basic defense mechanism of the immune system.

New study provides better understanding of blood clot formation in cancer patients

Researchers have identified a potential new signaling pathway that may help further the understanding of blood clot formation in cancer patients and ultimately help prevent this complication from occurring.

Researchers develop breakthrough in marine sponge cell culture

Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for many organisms, including freshwater and terrestrial invertebrates.
