Critical cellular functions, including stem cell maintenance, fate determination, and cellular behavior, are governed by canonical Wnt signaling, an evolutionarily conserved pathway whose intracellular signal is transduced by β-catentin. Emerging evidence suggests that canonical Wnt signaling influences cellular aging, indicating that increases in Wnt signaling delay age-related deficits.(1) However, recent Science papers suggest that Wnt signaling accelerates the onset of aging.(2,3) In an attempt to resolve this paradox and clarify how Wnt signaling affects aging, we provide a selective review of research relevant to Wnt signaling and aging.
