Infertility induced by auxin in PX627 Caenorhabditis elegans does not affect mitochondrial functions and aging parameters.

ABSTRACT: Caenorhabditis elegans is widely used for aging studies. 5-Fluoro-2´-deoxyuridine (FUdR) is commonly used to control offspring. While larvae are stopped from further development, also mitochondrial DNA and function may be affected. Since mitochondria and longevity are closely related, the use of FUdR may falsify possible studies. PX627, an auxin inducible infertility strain to control offspring, allows mitochondrial investigations during senescence without FUdR toxicity.Longevity and health parameters were assessed in 2- and 10-day old nematodes wild-type N2 and PX627 treated with FUdR or auxin, respectively. Mitochondrial membrane potential, energetic metabolites and reactive oxygen species levels, were determined. mRNA expression levels of key genes involved were quantified using
