STUDY FINDS TURNING POINT WHEN THE BODY STARTS AGEING RAPIDLY

While we can try to slow it down, human ageing is something that we currently cannot stop from happening. Past studies have shown that ageing does not necessarily happen at the same pace throughout our life. Instead, there are certain ages when a person's body may experience a burst of ageing. Previous studies indicate that the body may undergo rapid ageing around the ages of 44 and 60. But there is still much to discover about the ageing process, especially when it comes to how it impacts the body’s organs.

Ageing, as a systemic, degenerative process that spans multiple organs and biological strata, remains one of the most profound unresolved questions in the life sciences. Throughout the extended human lifespan, two fundamental issues persist: Do all organ systems adhere to a unified ageing rhythm? Does a molecular spatiotemporal hub exist that orchestrates organism-wide senescence? Despite their centrality to understanding the essence of ageing, these questions have long lacked systematic, empirical resolution.

In a new study recently published in the journal Cell, researchers have found that by focusing on ageing-related protein changes in the body, they can get a clearer picture of how the body’s organs and tissues age over time, including an ageing acceleration at around the age of 50. And of these proteins, the scientists found that expressions of 48 of them related to diseases such as cardiovascular disease and fatty liver disease increased with age.
