Abstract:Low temperatures slow aging and extend lifespan in many organisms, including Caenorhabditis elegans. However, the metabolic and homeostatic aspects of low temperature-induced longevity remain poorly understood. Here, we show that changes in lipid composition regulated by MDT-15/Mediator 15, transcriptional co-regulator, is essential for low temperature-induced longevity and proteostasis in C. elegans. We find that inhibition of mdt-15 prevents animals from living long at low temperatures. We show that MDT-15 u… Show more
