Signs of faster aging detectable via blood gene expression test

Supposedly, you're only as old as you feel. Still, the molecular changes that take place in cells during aging may have something to do with how old (or young) someone feels.

An international team of researchers have taken a step forward in unraveling these processes, by studying the changes in gene expression levels in blood in more than 15,000 people around the world. This was the largest human molecular aging study to date.
 
In addition, Karen Conneely, PhD, assistant professor of human genetics at Emory University School of Medicine and a faculty member in the GMB and PBEE programs, led a meta-analysis investigating relationships between DNA methylation, aging and gene expression in several of the participating cohorts.

Additional Emory authors include: Alicia K. Smith, PhD, assistant professor of psychiatry and behavioral sciences, director of the psychiatric genetics core, and GMB faculty member, and GMB graduate student, Elizabeth M. Kennedy.
