We have recently described thatsubmaximal inhibition of the Sarco-Endoplasmic Reticulum Ca2+ ATPase(SERCA), the main responsible for ER calcium storage, is able to increaselifespan in Caenorhabditis elegans worms by mechanisms involvingmitochondrial metabolism and nutrient-sensitive pathways.Methods: We have studied here the effects of submaximal SERCA inhibition in achemicalmodel of Parkinson’s disease (PD) induced in C. elegansworms by treatmentwith themitochondrial complex I inhibitor rotenone. For specific SERCA inhibition,wetreated worms with RNAi against sca-1, the sole orthologue of SERCA in C. elegans.Results and Discussion: Our results show that rotenone produces alterations inworms that include decreased lifespan, smaller size, reduced fertility, decreasedmotility, defecation and pumping rate, increased mitochondrial ROS production,reduced mitochondrial membrane potential and oxygen consumption rate, alteredmitochondrial structure, and altered ethanol preference in behavioral studies. Most ofthese alterations were either fully or partially reversed in worms treated with sca-1RNAi, suggesting that SERCA inhibition could be a novel pharmacological target in theprevention or treatment of neurodegeneration.
