Wu Group: Laboratory for Ageing Research

Our lab studies the molecular and metabolic mechanisms that underlie biological ageing, with a focus on its impacts on female fertility. A key mechanistic interest for the lab is the role of altered metabolism, including the molecular metabolism of the redox cofactor nicotinamide adenine dinucleotide (NAD+). Our group previously showed that declining levels of this cofactor are a reversible cause of reproductive ageing, a discovery that has resulted in ongoing clinical trial translation. We conduct experiments in C. elegans, mice and humans, with a wide variety of experimental techniques, in particular the use of stable isotope tracing and metabolomics to investigate unexpected aspects of textbook metabolic pathways.

Current projects

The Laboratory for Ageing Research is works on that could maintain healthy ageing. These have immediate applications in other conditions, including , preventing the long-term adverse effects of chemotherapy treatment, and unexplored aspects of cell biochemistry with age.

The following projects and more are available for study at both the honours and PhD level...

New treatments to maintain female fertility during biological ageing and following chemotherapy treatment
Role of the pentose phosphate pathway and the enzyme glucose-6-phosphate dehydrogenase in reproductive ageing
DNA transposons in genome instability and the regulation of lifespan
New treatments to reduce the side effects of chemotherapy and improve long-term health in cancer survivors
Studies of the metabolism of nicotinamide adenine dinucleotide (NAD⁺)
Understanding the role of somatic-germline interactions in reproductive ageing and lifespan
Tracing NAD+ turnover dynamics in humans
Changes in cellular metabolism during fertilization and embryo development as a treatment for age-related infertility
