In a new study from Sanford-Burnham Medical Research Institute (Sanford-Burnham), researchers have used human pluripotent stem cells to generate new hair. The study represents the first step toward the development of a cell-based treatment for people with hair loss. In the United States alone, more than 40 million men and 21 million women are affected by hair loss. The research was published online in PLOS One yesterday.

Despite enormous progress in cancer therapy, many patients still relapse because their treatment addresses the symptoms of the disease rather than the cause, the so-called stem cells. Work in the group of Veronika Sexl at the University of Veterinary Medicine, Vienna has given a tantalizing clue to a solution. In the current issue of Blood, the scientists report that the cell-cycle kinase CDK6 is required for activation of the stem cells responsible for causing leukemia.

Researchers have linked trimethylamine N-oxide (TMAO) - a gut metabolite formed during the digestion of eggs, red meat or dairy-derived nutrients choline and carnitine - to chronic kidney disease.
TMAO has been linked to heart disease already, with blood levels shown to be a powerful tool for predicting future heart attacks, stroke and death. TMAO forms in the gut during digestion of choline and carnitine, nutrients that are abundant in animal products such as red meat and liver. Choline is also abundant in egg yolk and high-fat dairy products.

In a study published in Molecular Metabolism, a SLU researcher has found that adropin, a hormone that regulates whether the body burns fat or sugar during feeding and fasting cycles, can improve insulin action in obese, diabetic mice, suggesting that it may work as a therapy for type 2 diabetes.

Almost 2,500 women of child-bearing age in the UK are at risk of transmitting mitochondrial disease to their children, according to the most recent estimates published today in the New England Journal of Medicine.
The research offers the most recent evidence yet of how many families could potentially be helped by new IVF techniques to prevent mitochondrial disease, which would be permitted by new regulations on which a vote in parliament is imminent.

Preventing inflammation in obese fat tissue may hold the key to preventing or even reversing type 2 diabetes, new research has found.
Researchers from Melbourne's Walter and Eliza Hall Institute and the RIKEN Institute, Japan found they could 'reverse' type 2 diabetes in laboratory models by dampening the inflammatory response in fat tissue.
Dr Ajith Vasanthakumar, Dr Axel Kallies and colleagues from the institute discovered that specialised immune cells, called regulatory T cells (Tregs), played a key role in controlling inflammation in fat tissue and maintaining insulin sensitivity.

Mitochondria produce ATP, the energy currency of the body. The driver for this process is an electrochemical membrane potential, which is created by a series of proton pumps. These complex, macromolecular machines are collectively known as the respiratory chain. The structure of the largest protein complex in the respiratory chain, that of mitochondrial complex I, has been elucidated by scientists from the Frankfurt "Macromolecular Complexes" cluster of excellence, working together with the University of Freiburg, by X-ray diffraction analysis.

Swedish studies show that mice that receive a supplement of the "appetite hormone" ghrelin increase their sexual activity. Whether the hormone has the same impact on humans is unknown - but if it does, the researchers may have found the key to future treatments for sex abuse.
Ghrelin is a gastrointestinal hormone that is released from the stomach, and is involved in the stimulation of our appetite by activating the brain's reward system.

Death rates from lung cancer will exceed those for breast cancer for the first time among European women in 2015, according to new predictions in Annals of Oncology .
The study predicts that although the actual number of deaths from all cancers in the European Union will continue to rise due to growing populations and numbers of elderly people, the rate of cancer deaths will continue to decline overall, with some notable exceptions: lung cancer in women and pancreatic cancer in both sexes.
