Potential relevance to dietary restriction and ageing

Observations

PNC-1 is a NAD+ salvage pathway enzyme, that is required for the lifespan-extension effect of dietary restricion. In PNC-1 null worms, the lifespan is extended by dietary restriction to a significantly smaller degree, and this effect was consistently observed at variuos degrees of restriction (from very mild to dietary deprivation). Contrastly, PNC-1 is not required for some of the healthspan benefits of dietary restriction. While pnc-1 mutants display a muscle function deficiency (shown by their rate of spontaneous body bending) compared to wild-type under ad libitum, dietary restriction comparably increases the frequency of bending in older wild-type and pnc-1 mutants. Additionally, thermotolerance, a measure which declines with age in C. elegans, is increased in both wild type and pnc-1 worms by dietary restriction.
