In fact, emerging evidence suggests that the cell cycle-independent metabolic oscillations interact with elements of the cell cycle machinery via several possible mechanisms. Furthermore, recent reports indicate that different biosynthetic processes exhibit temporally changing activity patterns during the cell cycle. Thus, resources are drawn from primary metabolism in a dynamic manner, potentially giving rise to metabolic oscillations.

Pathways regulating metabolism, including nutrient sensing, energy production, and synthesis and degradation of macromolecules, have been identified as key regulators of organismal lifespan and implicated in several late-onset diseases, such as most neurodegenerative disorders.

We highlight data demonstrating a reciprocal interaction between organelle (dys)-function and protein homeostasis in aging.
