A dual role of the Wnt signaling pathway during aging in Caenorhabditis elegans.

ABSTRACT: Wnt signaling is a major and highly conserved developmental pathway that guides many important events during embryonic and larval development. In adulthood, misregulation of Wnt signaling has been implicated in tumorigenesis and various age-related diseases. These effects occur through highly complicated cell-to-cell interactions mediated by multiple Wnt-secreted proteins. While they share a high degree of sequence similarity, their function is highly diversified. Although the role of Wnt ligands during development is well studied, very little is known about the possible actions of Wnt signaling in natural aging. In this study, Caenorhabditis elegans serves, for the first time, as a model system to determine the role of Wnt ligands in aging. Caenorhabditis elegans has five Wnt proteins, mo
