LifeGen Technologies

Science

The science of LifeGen Technologies utilizes DNA microarrays to identify changes in gene expression that are associated with the aging process and how these changes are opposed by caloric restriction (CR). The same process is being used by LifeGen scientists to screen for compounds that have the ability to mimic the transcriptional activity of CR.

This research will permit LifeGen to partner with companies to develop pharmaceutical and nutraceutical compounds to retard aging. LifeGen has also constructed an extensive, proprietary gene expression database on aging, which provides vital information to life sciences companies. Drs. Weindruch’s and Prolla’s knowledge, experience, and network of contacts in the gerontology, genetics and biotechnology industries provide LifeGen with the resources to be a leader in the field of aging genomics.
