DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Midbrain habenula region plays a key role in nicotine dependence

A person's vulnerability to nicotine addiction appears to have a genetic basis, at least in part. A region in the midbrain called the habenula plays a key role in this process, as Dr. In-s Iba-ez-Tallon and her team from the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now shown.

Noninvasive stool test can detect pancreatic cancer

Pancreatic cancer has one of the highest mortality rates of any of the major cancers, and of the 43,000-plus Americans diagnosed with the disease each year, more than 94 percent die within five years of diagnosis. One reason for this high number of deaths is a lack of effective screening tools for catching the disease early.

New research sheds light on common pathogenic mechanisms underlying Huntington's disease

New research sheds light on common pathogenic mechanisms shared by Huntington's disease (HD) and HD-like disorders. The study, published by Cell Press in the May 12, 2011, issue of the journal Neuron, uses a new transgenic mouse model for an HD-like disorder to unravel complex molecular events that drive disease pathology.

New genome-wide study identifies causes of serious childhood immune disorder

A new genomics study, led by the Center for Applied Genomics at The Children's Hospital of Philadelphia, sets the stage for the first predictive diagnostic test in a serious immunodeficiency disease in children. If the disorder, common variable immunodeficiency disease, can be diagnosed early, children may receive life-saving treatments before the disease can progress.
