High-content analysis achieves 20-fold increase in throughput

GE Healthcare has announced the winner of the first GE Healthcare HCA Award. Supported by BioTechniques, the Award recognizes the outstanding contribution of HCA to scientific understanding and celebrates its positive impact on data quality and quantity, resulting in increased productivity, deeper insights and better decisions.

The winner of the first HCA Award is Dr Michael Freeley from the Institute of Molecular Medicine, Trinity College Dublin (TCD), who investigates how white blood cells (T lymphocytes) move in the body during an immune response. Movement of T lymphocytes from the blood stream into target tissues is crucial in an effective immune response against disease-causing organisms, but unregulated migration of T lymphocytes is also a major contributor to auto-immune diseases such as multiple sclerosis, Crohn’s disease and rheumatoid arthritis. A better understanding of this process could ultimately lead to treatments that selectively block this migration in these diseases.

New potential for experimental drug to treat common womb cancer

A targeted drug that has shown promise in treating breast, ovarian and prostate cancer patients with few side-effects may also work for the most common type of womb cancer, according to a study in Science Translational Medicine.

A team from the Breakthrough Breast Cancer Research Centre at The Institute of Cancer Research (ICR) in London have shown that the new type of drug, called PARP inhibitors, can kill womb cancer cells that have a defective PTEN gene.

Studying self-assembled polymer/DNA particles

The Department of Biomedical Engineering, Johns Hopkins University School of Medicine is using the NanoSight LM10-HS system to study self-assembled polymer/DNA particles for drug delivery.

The main research interests of Dr Jordan Green of the Biomaterials and Drug Delivery Laboratory are in cellular engineering and nanobiotechnology. Knowledge of particle size is of particular value in the characterization of different drug delivery systems. Having had previous experience using dynamic light scattering techniques, Dr Green and his team now also use the complementary technique of nanoparticle tracking analysis from NanoSight. NTA provides insight into their samples particularly those with polydisperse behaviour.

A new role for an old protein

Hypertension is the leading contributor to global mortality, and is known to depend on the interaction of environmental and heritable factors. However, the genetic variations identified so far only explain 1-2% of the difference in blood pressure in the population, suggesting the presence of many more variations yet to be discovered.

A new genetic variation has just been identified by an international team of researchers, led by the University of Glasgow and Istituto Auxologico Italiano of Milano. This new genetic variation is associated with a reduced risk of hypertension, and also a reduced risk of cardiovascular disease events. Indeed, each copy of the variation – of which a person can have a maximum of two – was associated with a 7.7 per cent reduction of strokes, myocardial infarctions (heart attack) and coronary deaths.

Study on effects of anti-obesity drug on the brain paves way for more effective treatments

Scientists have revealed that an anti-obesity drug changes the way the brain responds to appetising, high-calorie foods in obese individuals. This insight may aid the development of new anti-obesity drugs which reduce the activity in the regions of the brain stimulated by the sight of tasty foods.

Researchers at the University of Cambridge discovered that the anti-obesity drug sibutramine reduced brain responses in two regions of the brain, the hypothalamus and the amygdala, both of which are known to be important in appetite control and eating behaviour. Their findings are reported today in The Journal of Neuroscience.

Consolidating HbA1c testing onto an immunoassay platform

As diabetes rates soar, consolidating HbA1c testing onto an immunoassay platform can solve throughput problems and reduce costs.

Roche offers free evaluation kit for the Tina-quant [a] HbA1c Generation 2 assay – an efficient, accurate, cost effective hbA1c testing solution that is easily consolidated onto several Roche platforms.

Diabetes is often in the news these days and almost all of us will know someone with the disease. Its prevalence in England alone is staggering – in 2004/5 3.3 per cent of the population were diagnosed diabetics, this increased to 4.1 per cent in 2008/91 and continues to grow. Reports from the National Heart Forum predict that type 2 diabetes rates are almost set to double by 20202. But the level of people with undiagnosed diabetes is also worrying.

Muscle strength gene variant linked to falls

Research published online in the Journal of Gerontology: Medical Sciences shows for the first time that a variant of the gene ACTN3 – already linked with muscle strength and power in elite athletes – is a risk factor for falling in older females.

But the scientists stress that falls are caused by a wide range of factors and that having this gene variant alone is not enough to cause elderly women to tumble.

All of us have two copies of the ACTN3 gene - inherited from our parents - which affects how the ACTN3 protein is expressed in muscle fibres, which in turn affects muscle power and strength.
