Picture a future where the ageing process can be slowed down or even reversed. This might not be science fiction anymore as leading scientists spanning from Cornell University, University of Oxford, University of Cambridge, and Cancer Research UK have embarked on an exploration deep into the body’s cells to better understand the natural ageing process. Pioneered by Professor Meng Wang, this research is investigating a potentially fundamental factor driving ageing: formaldehyde, a toxic chemical best known as an embalming agent.
Cells Naturally Produce Formaldehyde
Research suggests that cells naturally produce formaldehyde. More curiously, the adverse effects of this toxic chemical could be a contributor to the ageing process in our body’s cells. These findings may open the way to revolutionary anti-ageing drugs that target formaldehyde levels in the body, potentially reducing the risk of blood cancer and ageing-related decline. As Prof Wang, a haematology expert, explains, “We believe we have pinned down one of the potential causes of natural ageing.”
Ensuing from a genetic mutation, a novel blood condition has been discovered. This extremely rare condition, affecting fewer than one in a million people, doesn’t allow the body to flush out formaldehyde effectively, leading to the development of blood cancers. With formaldehyde’s ability to cause DNA damage to blood stem cells, thereby quickening their ageing process, it can notably up the chances of blood cancers, according to Cancer Research UK.
Speaking further on the impact of formaldehyde, Prof Wang elaborated, “What we found is that actually, at least in blood stem cells, the ageing process is very much a triggered response, dependent on a protein called p53.”
Mother Stem Cells and Ageing
The study also brings to light the role of hematopoietic stem cells, the mother cells that produce new blood cells, in this formaldehyde-driven ageing. These cells display diminished self-renewal capacity and a myeloid differentiation bias with age. However, the precise causes and mechanisms are still under scrutiny.
In the pursuit to understand formaldehyde production within the body, the research team has also started investigating possible influences from our diet and lifestyle on formaldehyde production levels. The potential effects of this chemical might not be limited to the blood, with early signs hinting towards accelerated ageing in other organs as well.
While these findings are noteworthy, Prof Meng Wang emphasizes that formaldehyde isn’t solely responsible for ageing, stating, “I don’t think it will ever be the case where if we remove formaldehyde we completely stop ageing because there’ll be other similar chemicals that will also be contributing to this.” The search continues for other chemicals that may influence ageing in a similar way.
The current research may only be the proverbial tip of the iceberg in the quest to understand the complex mechanisms of ageing. Yet, the association between formaldehyde and ageing offers a promising stepping stone towards potential therapeutic interventions in the future.
