PCH-2 regulates Caenorhabditis elegans lifespan


Figure 1. Pch-2 is an evolutionarily conserved gene and its expression declines with tissue aging across species. (A) Sequences alignment of pch-2 genes cross species ranging from yeast, worm, fly and rodent, to human. (B) Pch-2 mRNA expression changes with age in human, mouse and worm. * indicates p <0.05.
