Caenorhabditis Sieve: A Low-tech Instrument and Methodology for Sorting Small Multicellular Organisms Skyler Hunter*1,2, Malabika Maulik*3, Courtney Scerbak4, Elena Vayndorf2, Barbara E. Taylor5 1Department of Biology and Wildlife, University of Alaska Fairbanks, 2Institute of Arctic Biology, University of Alaska Fairbanks, 3Department of Chemistry and Biochemistry, University of Alaska Fairbanks, 4Departments of Biology and Chemistry, Earlham College, 5Department of Biological Sciences, College of Natural Science and Mathematics, California State University Long Beach The current protocol includes a methodology for the sorting and cleaning of age-matched populations of Caenorhabditis elegans. It uses a simple, inexpensive, and efficient custom-made tool to obtain a large experimental population of nematodes for research.

Lowbush Cranberry Acts Through DAF-16/FOXO Signaling to Promote Increased Lifespan and Axon Branching in Aging Posterior Touch Receptor Neurons GeroScience. 04, 2018 | Pubmed ID: 29717416 Medicinal berries are appreciated for their health benefits, in traditional ecological knowledge and nutrition science. Determining the cellular mechanisms underlying the effects of berry supplementation may contribute to our understanding of aging. Here, we report that lowbush cranberry (Vaccinium vitis-idaea) treatment causes marked nuclear localization of the central aging-related transcription factor DAF-16/FOXO in aged Caenorhabditis elegans. Further, functional DAF-16 is required for the lifespan extension, improved mechanosensation, and posterior touch receptor neuron morphological changes induced by lowbush cranberry treatments. DAF-16 is not observed in nuceli nor required for lifespan extension in lifespan-extending Alaskan blueberry treatments and, while DAF-16 is not visibly induced into the nucleus in lifespan-extending Alaskan chaga treatments, it is required for chaga-induced lifespan extension. These findings underscore the importance of DAF-16 in the aging of whole organisms and touch receptor neurons and also, importantly, indicate that this critical pathway is not always activated upon consumption of functional foods that impact aging.
