The nonhomologous end-joining pathway is a primary DNA double-strand break repair pathway in eukaryotes. DNA ligase IV (Lig4) catalyzes the final step of DNA end ligation in this pathway. Partial loss of Lig4 in mammals causes Lig4 syndrome, while complete loss is embryonically lethal. DNA ligase 4 (DNAlig4) null Drosophila melanogaster is viable, but sensitive to ionizing radiation during early development. We proposed to explore if DNAlig4 loss induced other long-term sensitivities and defects in D. melanogaster. We demonstrated that DNAlig4 mutant strains had decreased lifespan and lower resistance to nutrient deprivation, indicating Lig4 is required for maintaining health and longevity in D. melanogaster.
