Rates of heart disease, stroke continue to decline in Europe

The research, which provides an update for 2014 on the burden of cardiovascular disease (CVD) in Europe, shows that death rates from CVD (diseases of the heart and blood vessels) vary enormously. For some eastern European countries, including Russia and Ukraine, the death rate from coronary heart disease for 55-60 year olds is greater than the equivalent rate in France for people 20 years older. The age adjusted CVD death rates for men and women of all ages were six-fold higher in Russia than in France. In 2010 in Russia 915 men and 517 women died per 100,000 of the population, whereas the equivalent rates in France were 150 and 87 per 100,000 respectively. …

Microchip reveals how tumor cells transition to invasion

Using a microengineered device that acts as an obstacle course for cells, researchers have shed new light on a cellular metamorphosis thought to play a role in tumor cell invasion throughout the body. The epithelial-mesenchymal transition (EMT) is a process in which epithelial cells, which tend to stick together within a tissue, change into mesenchymal cells, which can disperse and migrate individually. EMT is a beneficial process in developing embryos, allowing cells to travel throughout the embryo and establish specialized tissues. But recently it has been suggested that EMT might also play a role in cancer metastasis, allowing cancer cells to escape from tumor masses and colonize distant organs…

New mouse model points to therapy for liver disease

Development of effective new therapies for preventing or treating NASH has been stymied by limited small animal models for the disease. In a paper published online in Cancer Cell, scientists at the University of California, San Diego School of Medicine describe a novel mouse model that closely resembles human NASH and use it to demonstrate that interference with a key inflammatory protein inhibits both the development of NASH and its progression to liver cancer. “These findings strongly call for clinical testing of relevant drugs in human NASH and its complications,” said senior author Michael Karin, PhD, Distinguished Professor of Pharmacology in UC San Diego’s Laboratory of Gene Regulation and Signal Transduction. “Our research has shown that, at least in this mouse model, chemical compounds that include already clinically approved drugs that inhibit protein aggregation can also be used to prevent NASH caused by a high fat diet.” The increasing prevalence of NAFLD is linked to the nation’s on-going obesity epidemic. …

New ways to treat solid tumors using protein — ScienceDaily

As EphA3 is present in normal organs only during embryonic development but is expressed in blood cancers and in solid tumors, this antibody-based approach may be a suitable candidate treatment for solid tumors. The researchers from Monash University and Ludwig Cancer Research, in Australia, and KaloBios Pharmaceuticals, in the US, have had their findings published in the journal Cancer Research. The team, led jointly by the late Professor Martin Lackmann, from the School of Biomedical Sciences at Monash; and Professor Andrew Scott, from Ludwig Cancer Research, has found that even if tumor cells do not have this molecule they can thrive by recruiting and taking advantage of supporting EphA3-containing cells in the tumor micro-environment…

Prostate cancer diagnosis improves with MRI technology — ScienceDaily

An ultrasound machine provides an imperfect view of the prostate, resulting in an under-diagnosis of cancer, said J. Kellogg Parsons, MD, MHS, the UC San Diego Health System urologic oncologist who, along with Christopher Kane, MD, chair of the Department of Urology and Karim Kader, MD, PhD, urologic oncologist, is pioneering the new technology at Moores Cancer Center. “With an ultrasound exam, we are typically unable to see the most suspicious areas of the prostate so we end up sampling different parts of the prostate that statistically speaking are more likely to have cancer,” said Parsons, who is also an associate professor in the Department of Urology at UC San Diego School of Medicine. “The MRI is a game-changer…
