Study reveals how one type of DNA damage may lead to several human diseases

Using a new imaging technique, National Institutes of Health researchers have found that the biological machinery that builds DNA can insert molecules into the DNA strand that are damaged as a result of environmental exposures. These damaged molecules trigger cell death that produces some human diseases, according to the researchers.

Sulindac drug can protect against oxidative damage due to AMD

While oxygen is essential to our planet's life force and the way we function and stay healthy, high concentrations referred to as oxidative stress may very well be the cause of more than 70 widely-spread diseases such as cancer, heart disease, neurodegenerative diseases, and eye diseases including macular degeneration.

Joslin researcher identifies molecular pathway that causes neural tube defects in diabetic pregnancies

Mary R. Loeken, Ph.D., Investigator in the Section on Islet Cell and Regenerative Biology at Joslin Diabetes Center and Associate Professor of Medicine at Harvard Medical School, has discovered a molecular pathway responsible for neural tube defects in diabetic pregnancies. Her latest research findings in this pathway were published in the October issue of Diabetes.
