MADISON -- Delving deep into the molecular subtleties of a strain of mice engineered to age rapidly, scientists have found that an accumulation of genetic mutations prompts a cascade of programmed cell death that seems to underpin the aging process. Writing today (July 15, 2005) in the journal Science, a team of scientists led by University of Wisconsin-Madison geneticist Tomas A. Prolla describes a series of experiments in mutant and normal mice that peel away some of the root secrets of...

A pilot study at the National Institute of Standards and Technology (NIST), in support of the National Cancer Institute's Early Detection Research Network (EDRN), has validated the measurement accuracy of new techniques that use mitochondrial DNA as an early indicator for certain types of cancer. Additional results suggest that a relatively simple diagnostic test using a DNA microarray "chip" could enable early detection of some solid tumors, including lung cancer. Mitochondrial DNA (mtDNA)...

Researchers offer distinctly nonmolecular solution: Exercise HealthDay News -- Researchers can now tell you why your legs get creakier and wearier as you get older -- it's the inevitable deterioration of the genetic material in the energy-producing centers of your muscle cells. "What we've shown here is an important first step to understanding aging in a specific organ of the human body," said Dr. Sreekumaran Nair, an endocrinologist at the Mayo Clinic and lead author of a report on the...
