However, the underlying molecular mechanism still remains elusive. The gene cbp-1, encoding the worm ortholog of p300\/CBP (CREB-binding protein), is one of the very few key genes known to be essential for life span doubling under axenic dietary restriction (ADR). By using tissue-specific RNAi, we found that cbp-1 expression in the germline is essential for fertility, whereas this gene functions specifically in the GABAergic neurons to support the full life span\u2013doubling effect of ADR. Surprisingly, GABA itself is not required for ADR-induced longevity, suggesting a role of neuropeptide signaling. In addition, chemotaxis assays illustrate that neuronal inactivation of CBP-1 affects the animals\u2019 food sensing behavior. Together, our results show that the strong life-span extension in axenic medium is under strict control of GABAergic neurons and may be linked to food sensing.<\/jats:p>","DOI":"10.1093\/gerona\/glx206","type":"journal-article","created":{"date-parts":[[2017,11,1]],"date-time":"2017-11-01T03:25:07Z","timestamp":1509506707000},"page":"1198-1205","source":"Crossref","is-referenced-by-count":27,"title":["CBP-1
