We have recently described that submaximal inhibition of the Sarco-Endoplasmic Reticulum Ca2+ ATPase (SERCA), the main responsible for ER calcium storage, is able to increase lifespan in Caenorhabditis elegans worms by mechanisms involving mitochondrial metabolism and nutrient-sensitive pathways. Methods: We have studied here the effects of submaximal SERCA inhibition in a chemicalmodel of Parkinson’s disease (PD) induced in C. elegansworms by treatment with themitochondrial complex I inhibitor rotenone. For specific SERCA inhibition,we treated worms with RNAi against sca-1, the sole orthologue of SERCA in C. elegans. Results and Discussion: Our results show that rotenone produces alterations in worms that include decreased lifespan, smaller size, reduced fertility, decreased motility, defecation and pumping rate, increased mitochondrial ROS production, reduced mitochondrial membrane potential and oxygen consumption rate, altered mitochondrial structure, and altered ethanol preference in behavioral studies. Most of these alterations were either fully or partially reversed in worms treated with sca-1 RNAi, suggesting that SERCA inhibition could be a novel pharmacological target in the prevention or treatment of neurodegeneration. application/pdf https://uvadoc.uva.es/handle/10324/66076 eng Frontiers 2411.99 Otras 3209.99 Otras SERCA inhibition improves lifespan and healthspan in a chemical model of Parkinson disease in Caenorhabditis elegans info:eu-repo/semantics/article TEXT UVaDOC.
