DNA News and Research

RSS

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).

Exposure to environmental estrogens during development of the prostate gland in the male fetus may lead to later prostate cancer risk

A study in the June 1 issue of Cancer Research presents the first evidence that exposure to low doses of environmental estrogens during development of the prostate gland in the male fetus may result in a predisposition to prostate cancer later in life.

Search for gene search for sporadic amyotrophic lateral sclerosis

Though it's the more common form of the disease, sporadic Amyotrophic Lateral Sclerosis (ALS), which affects roughly 90 percent of those living with the fatal neurodegenerative illness, has been the one less studied, simply because, unlike familial ALS, no genes have turned up.

Discovery of two gene variants associated with increased risk for early heart attack

Scientists at University of California - San Francisco (UCSF), Celera Genomics and The Cleveland Clinic have discovered two gene variants associated with a significantly increased risk for early heart attack, or myocardial infarction (MI).
