New way to make large concentrations of skeletal muscle cells from human stem cells

As stem cells continue their gradual transition from the lab to the clinic, a research group at the University of Wisconsin-Madison has discovered a new way to make large concentrations of skeletal muscle cells and muscle progenitors from human stem cells.

New insight into germline EGFR T790M mutation in familial non-small cell lung cancer

Two studies are providing new insight into germline epidermal growth factor receptor (EGFR) T790M mutation in familial non-small cell lung cancer (NSCLC). The findings suggest the need for tailored approaches for early detection and treatment, as well as for genetic testing to identify carriers.

CUMC researchers devise new system for classifying periodontal disease

Researchers at Columbia University Medical Center have devised a new system for classifying periodontal disease based on the genetic signature of affected tissue, rather than on clinical signs and symptoms. The new classification system, the first of its kind, may allow for earlier detection and more individualized treatment of severe periodontitis, before loss of teeth and supportive bone occurs.

People with rare inherited mutated gene have high chance of getting lung cancer

People who have an inherited mutation of a certain gene have a high chance of getting lung cancer — higher, even, than heavy smokers with or without the inherited mutation, according to new findings by cancer researchers at UT Southwestern Medical Center. Although both genders have an equal risk of inheriting the mutation, those who develop lung cancer are mostly women and have never smoked, the researchers found.

Women taking folic acid supplement may be at risk of reducing folate benefit through sun exposure

Women who are pregnant or trying to fall pregnant and taking a folic acid supplement may be at risk of reducing their folate benefit through sun exposure, a new QUT study has warned.

Measuring circulating tumor cells may help better predict prostate cancer survival

New research by USC Norris Comprehensive Cancer Center scientists demonstrates that measuring circulating tumor cells (CTCs) - the cells that spread cancer through the body - may be a better predictor of patient survival than the prostate specific antigen (PSA).

Scientists develop unique cells to repair patient's defective and diseased bladder

For the first time, scientists have succeeded in coaxing laboratory cultures of human stem cells to develop into the specialized, unique cells needed to repair a patient's defective or diseased bladder.

Rare abnormality in chromosomes increases risk of rare childhood leukaemia

Researchers have found that people born with a rare abnormality of their chromosomes have a 2,700-fold increased risk of a rare childhood leukaemia. In this abnormality, two specific chromosomes are fused together but become prone to catastrophic shattering.

Researchers uncover cause of rare type of ovarian cancer that strikes girls and young women

The cause of a rare type of ovarian cancer that most often strikes girls and young women has been uncovered by an international research team led by the Translational Genomics Research Institute, according to a study published online today by the renowned scientific journal, Nature Genetics.

Scientists explore link between SCN10A and cardiac arrhythmia risk

Although genome-wide association studies have linked DNA variants in the gene SCN10A with increased risk for cardiac arrhythmia, efforts to determine the gene's direct influence on the heart's electrical activity have been unproductive. Now, scientists from the University of Chicago have discovered that these SCN10A variants regulate the function of a different gene, SCN5A, which appears to be the primary gene responsible for cardiac arrhythmia risk.

Scientists unlock one of mysteries of modern genetics

Scientists at Indiana University have unlocked one of the mysteries of modern genetics: how acquired traits can be passed between generations in a process called epigenetic inheritance. The new work finds that cells don't know to silence some genes based on information hardwired into their DNA sequences, but recognize heritable chemical marks that are added to the genes. These chemical tags serve as a form of molecular memory, allowing cells to recognize the genes and remember to silence them again in each new generation.

Misplaced protein provides promising drug target for kidney cancer

The shortage of oxygen, or hypoxia, created when rapidly multiplying kidney cancer cells outgrow their local blood supply can accelerate tumor growth by causing a nuclear protein called SPOP-which normally suppresses tumor growth-to move out of the nucleus to the cytoplasm, where it has the opposite effect, promoting rapid proliferation.

Researchers find immune receptor for uric acid crystals

The surface of immune system cells is home to a number of receptors which are able to detect pathogens. As soon as these receptors are activated, inflammation occurs and the body's defense mechanisms kick in. Immune cells also have receptors that regulate or even suppress immunological responses to prevent damage to individual cells.

Researchers identify steps by which cell removes RNA from cytoplasm

RNA encodes the proteins that play a key role in cellular reproduction, but the manner in which cells regulate its removal once these proteins are synthesized remains a mystery. One piece of this mystery has been solved as researchers at the University of North Carolina at Chapel Hill who have identified the steps by which a cell removes RNA from the cytoplasm.

Study: Fatty fold of tissue can help heal diseased kidneys

A fatty fold of tissue within the abdomen that is a rich source of stem cells can help heal diseased kidneys when fused to the organs, according to a study conducted in rats.

Drug and alcohol abuse could be linked with poor development of "love hormone"

Addictive behavior such as drug and alcohol abuse could be associated with poor development of the so-called "love hormone" system in our bodies during early childhood, according to researchers at the University of Adelaide.

Researchers identify genetic defect that causes a subset of irritable bowel syndrome

Is irritable bowel syndrome (IBS) caused by genetics, diet, past trauma, anxiety? All are thought to play a role, but now, for the first time, researchers have reported a defined genetic defect that causes a subset of IBS. The research was published in the journal Gastroenterology.

Neuroscientist explores how the brain restores blood flow to damaged tissue following stroke

A neuroscientist at the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech says she hopes that a better understanding of how the brain restores blood flow to damaged tissue following a stroke will offer new treatment clues for a leading cause of death in the United States.
