Suppressing clk-1 restores lifespan and mitochondrial function in psd-1 deficient worms

Targeting ubiquinone biosynthesis counteracted reduced oxygen consumption and rescued lifespan loss caused by mitochondrial phosphatidylethanolamine deficiency in…Targeting ubiquinone biosynthesis counteracted reduced oxygen consumption and rescued lifespan loss caused by mitochondrial phosphatidylethanolamine deficiency in Caenorhabditis elegans.

(A) Comparative images of C. elegans reveal a developmental delay in psd-1 knockdown animals relative to control worms fed with HT115 (EV, empty vector) rescued by ethanolamine supplementation.

Vitamin C did not slow growth of mutated blood-cell groups

Median growth of mutated blood-cell groups was 0.016 per year lower with vitamin C than placebo, but the results were consistent with no difference.Median growth of mutated blood-cell groups was 0.016 per year lower with vitamin C than placebo, but the results were consistent with no difference.
