Potential universal strategy for treating drug addiction

An international research team led by the University of Saskatchewan has discovered a signaling pathway in the brain involved in drug addiction, together with a method for blocking its action, that may point to a single treatment strategy for most addictions.

Chink in cancer's armor

Much as the famed starship Enterprise would deploy a deflector shield to evade enemy attack, tumor cells are capable of switching on a molecular force field of their own to fend off treatments aimed at killing them. Now University of Florida researchers have found a chink in their armor.

DNA end caps may lead to cancer treatments

The two ends of human DNA have different structures that are treated differently as a cell divides, UT Southwestern Medical Center researchers have found in a study that could help lead to cancer therapies.

Research sheds light on origins of "junk" DNA

In experiments with transgenic mice, University of Pennsylvania School of Medicine researchers discovered the remaining steps in the complicated process of how the largest class of jumping genes replicates and inserts themselves within the human genome.

Intracellular observation of RNA metabolism will help identify disease-associated RNAs

For the first time, researchers can now peer inside intact cells to not only identify RNA-binding proteins, but also observe-in real-time-the intricate activities of these special molecules that make them key players in managing some of the cell's most basic functions.

Fatty acids such as those found in corn oil turn on genes that stimulate tumor growth

Omega-6 fatty acids--such as those found in corn oil--caused human prostate tumors in cell culture to grow twice as quickly as tumors to which omega-6 fats had not been added, according to a study conducted at the San Francisco VA Medical Center.

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme, an important contributor to the vast majority of human cancers. Understanding the physical shape of the protein has led to a better understanding of how it acts to immortalize cells - and should help scientists design broadly effective cancer drugs.

Thiamin supplements may help protect heart failure patients

Among patients hospitalized with heart failure, about one in three has deficient levels of thiamin, although thiamin deficiency was less common among those patients who were taking vitamin supplements, according to a new study in the Jan. 17, 2006, issue of the Journal of the American College of Cardiology.
