Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

Mouse model may provide clues on mechanism that links diabetes and aging to Alzheimer's

Growing evidence suggests that there may be a link between diabetes and Alzheimer's disease, but the physiological mechanisms by which diabetes impacts brain function and cognition are not fully understood. In a new study published in Aging Cell, researchers at the Salk Institute for Biological Studies show, for the first time, that diabetes enhances the development of aging features that may underlie early pathological events in Alzheimer's.

Study describes how Dbr1 gene halts toxic buildup of TDP-43-a protein

Scientists at the Gladstone Institutes and the Stanford University School of Medicine have discovered how modifying a gene halts the toxic buildup of a protein found in nerve cells. These findings point to a potential new tactic for treating a variety of neurodegenerative conditions, including amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease)-a fatal disease for which there is no cure.

Researchers figure out 3D shape of promising TB drug target

Researchers at Johns Hopkins have figured out the three-dimensional shape of the protein responsible for creating unique bonds within the cell wall of the bacteria that cause tuberculosis. The bonds make the bacteria resistant to currently available drug therapies, contributing to the alarming rise of these super-bacteria throughout the world.

New federal funding enables researchers to unravel how humans develop cancers

A Simon Fraser University scientist working at one of Canada's first epigenomics mapping centres says new federal funding will accelerate researchers' ability to unravel how we develop some of the most common life threatening cancers.

mTor molecule plays a significant role in myeloid differentiation

University of Illinois cell and developmental Biology professor Fei Wang and colleagues have created a new technique to study how myeloids, a type of blood stem cell, become the white blood cells important for immune system defense against infections and tissue damage.

Zebrafish model can test unique individual genetic differences in humans

The zebrafish is a potential tool for testing one class of unique individual genetic differences found in humans, and may yield information helpful for the emerging field of personalized medicine, according to a team led by Penn State College of Medicine scientists. The differences, or mutations, in question create minor changes in amino acids -- the building blocks of DNA -- from person to person.

Senate panel says Medtronic ghostwrote positive medical journal studies on its spine treatment product

A Senate Finance Committee investigation also alleges that the company paid $210 million to 13 doctors who co-authored the studies.

CTCtrap can capture circulating tumour cells in cancer patients

The 7.5 millilitres of blood contained in a standard sample tube is not nearly enough to detect circulating tumour cells (CTCs) in the blood of patients with metastatic breast cancer, prostate cancer, or colorectal cancer with a high enough degree of reliability. These CTCs are the cause of metastases in cancer patients. If they can be effectively characterized, it is possible to arrive at a prognosis and to determine the most effective course of treatment.

CUMC researchers develop first true mouse model of typhoid infection

Columbia University Medical Center (CUMC) researchers have created the first true mouse model of typhoid infection. The development promises to advance the study of typhoid and the creation of new vaccines against the infection, which remains a major health threat in developing countries.

Study identifies essential mechanism that regulates calcium flow into mitochondria

Most healthy cells rely on a complicated process to produce the fuel ATP. Knowing how ATP is produced by the cell's energy storehouse - the mitochondria -- is important for understanding a cell's normal state, as well as what happens when things go wrong, for example in cancer, cardiovascular disease, neurodegeneration, and many rare disorders of the mitochondria.

New study offers hope for lonely older adults at increased risk of health problems

Always look on the bright side of life. Thanks to a new study from Concordia University, this catchy refrain offers a prescription for staying healthy during one's golden years.

Artificial CSP proteins reduce S. pneumoniae competence y more than 90%

The bacterium Streptococcus pneumoniae - which can cause pneumonia, meningitis, bacteremia and sepsis - likes to share its antibiotic-defeating weaponry with its neighbors. Individual cells can pass resistance genes to one another through a process called horizontal gene transfer, or by "transformation," the uptake of DNA from the environment.

HCFC1 protein may cause intellectual disability

Genetics researchers at the University of Adelaide have solved a 40-year mystery for a family beset by a rare intellectual disability - and they've discovered something new about the causes of intellectual disability in the process.

Omega-3 fatty acid can enhance cognition in highly functional young individuals

While Omega-3 essential fatty acids-found in foods like wild fish and grass-fed livestock-are necessary for human body functioning, their effects on the working memory of healthy young adults have not been studied until now.

Three new gene variants associated with BMI levels in adults

A large international study has identified three new gene variants associated with body mass index (BMI) levels in adults. The scientific consortium, numbering approximately 200 researchers, performed a meta-analysis of 46 studies, covering gene data from nearly 109,000 adults, spanning four ethnic groups.
