Expression profiling of aging liver in low-fat diet mice

Dietary interventions are effective ways to extend or shorten lifespan. By examining midlife hepatic gene expressions in mice under different dietary conditions, which resulted in different lifespans and aging-related phenotypes, we were able to identify genes and pathways that modulate the aging process. To determine how our dietary intervention-based transcriptomic approach for predicting aging-regulatory genes compares to more traditional approach of using age-dependent transcriptional changes, we examined the hepatic gene expression changes in LF-fed mice during aging at 4, 8, 13 and 21 months.
