Yale Researchers Discover New Cancer Cell Vulnerability

July 21, 2014

1 Comment

New research from Yale University found that simultaneous inhibition of both telomerase and p21 inhibited tumor growth in mice. Yale School of Medicine and Yale Cancer Center researchers have uncovered a genetic vulnerability of cancer cells that express telomerase — an enzyme that drives their unchecked growth — and showed that telomerase-expressing cells depend upon […]

New Way to Regrow Human Corneas Could Help Overcome a Major Cause of Blindness

July 16, 2014

1 Comment

Harvard-affiliated researchers have discovered a new way to regrow human corneas that could help researchers overcome a major cause of blindness. Researchers have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule that acts as a marker for hard-to-find limbal stem cells. This work, a collaboration among the […]

Yale Study Shows Links between Smoking and Education

May 23, 2014

3 Comments

A newly published study from Yale University reveals that the links between smoking and education in adulthood are in fact explained by characteristics and choices made in adolescence. It’s well established that adults with college degrees are much less likely to smoke than adults with less education, but the reasons for this inequality are unclear. […]

RNA-Carrying Nanoparticles Deliver siRNA to Endothelial Cells with High Efficiency

May 12, 2014

0 Comments

Researchers have designed RNA-carrying nanoparticles that can deliver siRNA to endothelial cells with high efficiency, raising the possibility of treating many types of disease, including cancer and cardiovascular disease. RNA interference (RNAi), a technique that can turn off specific genes inside living cells, holds great potential for treating many diseases caused by malfunctioning genes. However, […]

Infusion of Young Blood Reverses Age-Related Impairments in Mice

May 6, 2014

3 Comments

A newly published study from Stanford University found that an infusion of young blood can counteract and reverse pre-existing effects of brain aging at the molecular, structural, functional and cognitive level in mice. Something — or some things — in the blood of young mice has the ability to restore mental capabilities in old mice, […]

Researchers Show that GDF11 Improves Functioning of Aged Brains and Muscles

May 5, 2014

0 Comments

In two new studies, researchers from the Harvard Stem Cell Institute show that injections of GDF11 improved the exercise capability and the function of the olfactory region of the brain in older mice. Harvard Stem Cell Institute (HSCI) researchers have shown that a protein they previously demonstrated can make the failing hearts in aging mice […]

MPI Researchers Discover a Gene that Controls Fat Metabolism

April 29, 2014

0 Comments

Researchers from the Max Planck Institute have discovered that the SIRT7 gene plays a central role in energy metabolism, revealing that genetically modified mice that lack the gene maintain their normal weight even when consuming high-fat food. The long-term consumption of too much high-energy and high-fat food leads to overweight. Behind this trivial statement lies […]
