Learning from the worm: the effectiveness of protein-bound Moco to treat Moco deficiency

Abstract

Molybdenum cofactor (Moco) is synthesized endogenously in humans and is essential for human development. Supplementation of Moco or its precursors has been explored as a therapy to treat Moco-deficient patients but with significant limitations. By using the nematode C. elegans as a model, Warnhoff and colleagues (pp. 212–217) describe the beneficial impact of protein-bound Moco supplementation to treat Moco deficiency. If such an effect is conserved, this advance from basic research in worms may have significant clinical implications as a novel therapy for molybdenum cofactor deficiency.
