Metolazone upregulates mitochondrial chaperones and extends lifespan in Caenorhabditis elegans.

abstract：:The primary determinant of survival during aging is the energetic efficiency and metabolic stability required to counter the accumulated internal and external stresses of a lifetime. Hence, genetically stress-resistant individuals should accumulate with age; frailer, less robust, less energetically efficient and less ...
