DNA News and Research

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).

Regular screening for colorectal cancer remains effective in preventing and detecting disease early

As the nation marks National Colorectal Cancer Awareness Month this March, the American Cancer Society is encouraging Americans to get lifesaving screening tests that have been proven to reduce the risk of the third leading cause of cancer death in both men and women.

New gene associated with Lou Gehrig's disease

A collaborative research effort spanning nearly a decade between researchers at Massachusetts General Hospital (MGH) and King's College London (KCL) has identified a novel gene for inherited amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease).

Novel approach to gene hunting uncovers possible new targets for Crohn's disease drugs

Discovering the different genes that contribute to a complex disease is like searching in the proverbial haystack for an unknown number of needles--some much smaller than others, often blending into the background, and many of them widely separated from each other.
