3D structure of enzyme helps defend against bacteria

An essential weapon in the body's fight against infection has come into sharper view. Researchers at Princeton University have discovered the 3D structure of an enzyme that cuts to ribbons the genetic material of viruses and helps defend against bacteria.

Childhood brain cancer (ETMR/ETANTR): an interview with Dr. Nada Jabado, Department of Pediatrics at McGill University

Embryonal tumours with multilayered rosettes (ETMR) are rare, deadly brain tumours that affect mainly children below the age of 4 years. There are 300 cases reported but probably there are many more as this tumour is often misdiagnosed.

Scientists reveal how MRSA strain rapidly rises to prominence

Scientists believe they have an explanation for how the most common strain of methicillin-resistant Staphylococcus aureus rapidly rose to prominence. Research published in mBio-, the online open-access journal of the American Society for Microbiology, suggests that the strain recently acquired a number of genes from common skin bacteria that allow it to grow and thrive on the skin where other strains of MRSA cannot.

Brain & Behavior Research Foundation announces recipients of NARSAD Investigator Grants

The Brain & Behavior Research Foundation (formerly known as NARSAD, the National Alliance for Research on Schizophrenia and Depression), under the direction of Dr. Jeffrey Borenstein, President & CEO, has announced the latest recipients of its NARSAD Distinguished Investigator Grants.

Researchers examine evolutionary selective pressure for MC1R gene among Spaniard and European populations

The proclivity of Spaniards to bask in regions like the Costa del Sol while their northern European counterparts must stay under cover to protect their paler skin or risk skin cancer is due in large part to the pigment producing qualities of the MC1R gene locus.

Locus coeruleus plays major role in learning, memory and other cognitive functions

Death of neurons in the dorsal raphe nucleus and locus coeruleus is a pathological characteristic of the disease. Previous studies concerning the pathological characteristic of Alzheimer's disease mainly focus on learning and memory-related hippocampus, and less attention has been paid to the locus coeruleus.

Aortic stenosis doubles in patients with family history of the condition

Aortic stenosis is the most common heart valve disease in the elderly. It is associated with congenital bicuspid aortic valve and previous rheumatic heart disease, but is also often caused by calcification of a normal valve. Calcification of a normal valve may be associated with atherosclerotic changes in the portion of the aorta closest to the valve.

Researchers identify genetic locus associated with increased risk of CHD in type 2 diabetes patients

Researchers have identified a previously unknown genetic locus (the place a gene occupies on a chromosome) significantly associated with increased coronary heart disease risk among patients with type 2 diabetes, but the association was not found in individuals without diabetes, according to a study in the August 28 issue of JAMA.

Researchers identify genome-wide locus for serious gastrointestinal condition in infants

Researchers have identified a new genome-wide significant locus (the place a gene occupies on a chromosome) for infantile hypertrophic pyloric stenosis (IHPS), a serious gastrointestinal condition associated with gastrointestinal obstruction, according to a study in the August 21 issue of JAMA. Characteristics of this locus also suggest the possibility of an inverse relationship between levels of circulating cholesterol in neonates and IHPS risk.

New approach may reduce time to identify Salmonella strains, say researchers

A new approach may be able to reduce by more than half the time it takes health officials to identify Salmonella strains, according to researchers in Penn State's College of Agricultural Sciences.

Study finds broader set of concerns for improving quality of life

The majority of cancer doctors, patients, and members of the general public support cutting health care costs by refusing to pay for drugs that don't improve survival or quality of life, according to results of a new study that will be presented by researchers from the Perelman School of Medicine at the University of Pennsylvania during the annual meeting of the American Society of Clinical Oncology in Chicago in early June (Abstract #6518).

Variations in the sequencing of TERT gene influence risk of breast, ovarian cancers

A major international study involving a Simon Fraser University scientist has found that sequence differences in a gene crucial to the maintenance of our chromosomes' integrity predispose us to certain cancers.

Scientists study repeating patterns in nature to better understand role of immune system in cancer

Can the patterns in tree branches or the meandering bends in a river provide clues that could lead to better cancer therapies? According to a new study from Virginia Commonwealth University Massey Cancer Center, these self-similar, repeating patterns in nature known as fractals help scientists better understand how the immune system is organized and may one day be used to help improve stem cell transplant outcomes in leukemia patients by predicting the probability of transplant complications.

Study identifies gene variants associated with histological features of NAFLD

More patients could be diagnosed earlier with non-alcoholic fatty liver disease after a cohort study presented at the International Liver Congress 2013 identified variants within four genes significantly associated with the histological features of the disease.

North American scientists chart new territory in immunity research

Cracking the DNA code for a complex region of the human genome has helped 14 North American scientists, including five at Simon Fraser University, chart new territory in immunity research.

Study shows TOLLIP gene variant is linked to increased mortality risk in IPF patients

A new study looking at the genomes of more than 1,500 patients with idiopathic pulmonary fibrosis, a rare and devastating lung disease, found multiple genetic associations with the disease, including one gene variant that was linked to an increase in the risk of death.

Researchers study gene that contributes to late-onset Alzheimer's disease in African-Americans

Researchers at Mayo Clinic in Florida participated in a nationwide study that found minor differences between genes that contribute to late-onset Alzheimer's disease in African-Americans and in Caucasians.

Study uncovers new relationship between nuclear architecture, gene activity

Every time a cell divides it makes a carbon copy of crucial ingredients, including the histone proteins that are responsible for spooling yards of DNA into tight little coils.

Research shows changes in mouse coat color were the result of nine mutations within a single gene

For deer mice living in the Nebraska Sandhills, color can literally be the difference between life and death. When they first colonized the region, the dark-coated mice stood out starkly against the light-colored, sandy soil, making them easy prey for predators.
