DALLAS - November 15, 2014 - A novel looping mechanism that involves the end caps of DNA may help explain the aging of cells and how they initiate and transmit disease, according to new research from UT Southwestern Medical Center cell biologists.
The UT Southwestern team found that the length of the endcaps of DNA, called telomeres, form loops that determine whether certain genes are turned off when young and become activated later in life, thereby contributing to aging and disease.
