New genetic pathway influences spread of cancer cells

In a new study from Lawson Health Research Institute, Dr. Joseph Torchia has identified a new genetic pathway influencing the spread of cancer cells. The discovery of this mechanism could lead to new avenues for treatment.

Researchers identify switches that can turn on or off genes associated with colorectal cancer

Two researchers at the Geisel School of Medicine at Dartmouth have helped to identify switches that can turn on or off genes associated with colorectal cancer. The finding offers clues about the development of colorectal cancer and could-potentially-provide targets for new therapies.

Hypoxia may be a primary cause of uncontrollable tumor growth in cancers

Low oxygen levels in cells may be a primary cause of uncontrollable tumor growth in some cancers, according to a new University of Georgia study. The authors' findings run counter to widely accepted beliefs that genetic mutations are responsible for cancer growth.

Scientists identify first gene associated with congenital asplenia

Researchers at Weill Cornell Medical College and Rockefeller University have identified the first gene to be linked to a rare condition in which babies are born without a spleen, putting those children at risk of dying from infections they cannot defend themselves against. The gene, Nkx2.5, was shown to regulate genesis of the spleen during early development in mice.

Blond gene among Solomon islanders baffles researchers

It is known that skin and hair color is mostly inherited from parents but whole populations have evolved to share certain traits. It is also known that people who live closer to the equator have darker skin and hair colour to protect against the Sun. The exception is found in the Solomon Islands, an archipelago east of Papua New Guinea which has the highest proportion of natural blonds outside of Europe despite being just south of the equator.

Therapy to halt symptoms in Parkinson's patients

Parkinson's disease, a disorder which affects movement and cognition, affects over a million Americans, including actor Michael J. Fox, who first brought it to the attention of many TV-watching Americans. It's characterized by a gradual loss of neurons that produce dopamine. Mutations in the gene known as DJ-1 lead to accelerated loss of dopaminergic neurons and result in the onset of Parkinson's symptoms at a young age.

Ambitious international project aims to compile landmark sequel to 'The Book of Life'

Scientists are announcing the roadmap, policies and procedures for an ambitious international project that aims to compile a landmark sequel to "The Book of Life." The follow-up to the Human Genome Project, which decoded all of the genes that make up humans, involves identifying and profiling all of the proteins produced by the thousands of genes bundled together in all of the human chromosomes.

Sleep adequately to maintain healthy weight

The genes behind weight gain may work overtime with lack of sleep says the study in this week's issue of the journal Sleep. In the study, neurologist Dr. Nathaniel Watson of the University of Washington Medicine Sleep Center in Seattle looked at the height, weight and sleep habits of 604 pairs of identical twins and 484 fraternal twins with an average age of 37.

A test to predict breast cancer many years before the disease is diagnosed

Ultimately the findings, in the journal Cancer Research, could lead to a simple blood test to screen women, they say. The test looks for how genes are altered by environmental factors like alcohol and hormones - a process known as epigenetics. One in five women is thought to have such a genetic “switch” that doubles breast cancer risk say researchers.

Large-scale, patient-specific simulations of blood function

Having a virtual copy of a patient's blood in a computer would be a boon to researchers and doctors. They could examine a simulated heart attack caused by blood clotting in a diseased coronary artery and see if a drug like aspirin would be effective in reducing the size of such a clot.

Novel stem cell transplantation holds promise for HIV prevention

UC Davis Health System researchers are a step closer to launching human clinical trials involving the use of an innovative stem cell therapy to fight the virus that causes AIDS.

Study reveals evidence about harmful effects of glycogen accumulation in neurons

Collaborative research by groups headed by scientists Joan J. Guinovart and Marco Mil-n at the Institute for Research in Biomedicine (IRB Barcelona) has revealed conclusive evidence about the harmful effects of the accumulation of glucose chains (glycogen) in fly and mouse neurons.

Rapamycin could help prevent autism in newborns with seizures

Early-life seizures are known to be associated with autism, and studies indicate that about 40 percent of patients with autism also have epilepsy. A study from Boston Children's Hospital finds a reason for the link, and suggests that an existing drug, already shown to be safe in children, could help prevent autism from developing in newborns who have seizures.

Smokers with variants in specific genes at increased risk for hot flashes

Women who smoke and carry specific variations in the genes that impact their metabolism are at higher risk of developing hot flashes in comparison with smokers who do not carry these gene variants, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism.

New bio-inspired approach can synthesize polymers

A new bio-inspired approach to synthesising polymers will offer unprecedented control over the final polymer structure and yield advances in nanomedicine, researchers say.

JS Genetics announces availability of XCAT-KS buccal swab test

JS Genetics announces the availability of XCAT-KS, its proprietary buccal swab test for the diagnosis of Klinefelter syndrome (KS) and other male sex chromosome aneuploidies.

Study investigates use of stem cells to treat lower-limb peripheral artery disease

Research led by vascular surgeons at Dartmouth-Hitchcock may offer new hope to sufferers of peripheral artery disease, the cause of nearly 60,000 lower-limb amputations annually, through the use of a patient's own stem cells.

Parental history of psychosis linked with increased risk of epilepsy in offspring

Although the two disorders may seem dissimilar, epilepsy and psychosis are associated. Individuals with epilepsy are more likely to have schizophrenia, and a family history of epilepsy is a risk factor for psychosis. It is not known whether the converse is true, i.e., whether a family history of psychosis is a risk factor for epilepsy.

Expression of tyrosine kinases may limit effectiveness of agents against sarcomas

To better understand the signaling pathways active in sarcomas, researchers at Moffitt Cancer Center used state-of-the-art mass spectrometry-based proteomics to characterize a family of protein enzymes that act as "on" or "off" switches important in the biology of cancer. The tyrosine kinases they identified, the researchers said, could act as "drivers" for the growth and survival of sarcomas.
