- New technique reveals subtle force-induced changes in biomolecule's conformation
10-15-2007 · EurekAlert!
Scientists studying biological systems at the molecular level now have a new hybrid technique to probe the dynamics of the Holliday junction. The Holliday junction is a four-stranded DNA structure that forms during a process known as homologous recombination, which occurs when damaged DNA is repaired. Understanding how DNA repairs itself is an essential step in ultimately developing therapies for genetic disorders.

- Gene found to play a suppressor role in skin cancer development
02-06-2008 · EurekAlert!
Researchers at the Burnham Institute for Medical Research have provided genetic evidence that Activating Transcription Factor 2 plays a suppressor role in skin cancer development. ATF2 is a protein that regulates gene transcription, the first step in the translation of genetic code, in response to extracellular stresses such as ultraviolet light and ionizing radiation. This function of ATF2 in stress and DNA damage response suggests it may also play a role in tumor formation.

- Chronic stress can steal years from caregivers' lifetimes
09-18-2007 · EurekAlert!
The chronic stress that spouses and children develop while caring for Alzheimer's disease patients may shorten the caregivers' lives by as much as four to eight years, a new study suggests. The research also provides concrete evidence that the effects of chronic stress can be seen both at the genetic and molecular level in chronic caregivers' bodies.
