Protein oxidation during aging of the nematode Caenorhabditis elegans.

The nematode Caenorhabditis elegans has proven a robust genetic model for studies of aging, including the roles of oxidative stress and protein damage. In this review, we focus on the genetics of select long-lived (e.g., age-1, daf-2, daf-16) and short-lived (e.g., mev-1) mutants that have proven useful in revealing the relationships that exist among oxidative stress, life span, and protein oxidation. The former are known to control an insulin/IGF-1-like pathway in C. elegans, while the latter affect mitochondrial function.
