Human aging has a turning point at 50 when the tissues age more quickly, shows the study

Aging seems to occur in a linear way throughout the human life, from childhood to “golden years”, but a new study revealed a specific turning point when aging begins to accelerate in the body.
Researchers in China discovered that at the age of 50, tissues and organs are starting to age at a faster rate.
“ Body clock ” could determine biological age and longevity, say researchers
The results were based on a study of 516 samples taken from 13 human tissues covering five decades.
The analysis revealed a wave of about 50 years, led by blood vessels which are “clearly sensitive” to aging.

To understand how individual organs are aging, the researchers also removed tissue samples from 76 Chinese organ donors aged 14 to 68, who all suffered from accidental traumatic brain damage.
The samples covered seven systems, including cardiovascular, digestive, immune, endocrine, respiratory, seeding (skin) and musculoskeletal, as well as blood samples.

Researchers have found that between ages of 45 and 55, many tissues undergo “substantial proteomic remodeling” (major changes in proteins), especially in the aorta (main cardiac artery), which makes them more sensitive to aging.

“Together, our results set the foundations for an understanding in terms of human aging systems through the protein lens,” summed up the researchers.
The co-author of the Guangui Liu study, a researcher at the Beijing Institute for stem cells and regenerative medicine, discussed the results of the study in an interview with Fox News Digital.

Although aging implies a “multi-organization decline,” said the study was aimed at determining whether the organs age at a “unique pace”.
Certain substances in the blood – called “Senokines” – work as a kind of clock that follows aging, then accelerates it, according to the expert.

The blood vessels are among the first parts of the body to show signs of aging, according to the researcher, because they release proteins which can influence the way the whole body ages.
Rather than something that happens to an organ at a time, the results suggest that aging should be considered an entire body process.

Liu suggested that binding tissue and plasma profiles in the human body could allow “non -invasive” age assessments based on blood samples.
This could help allow early and targeted interventions to counter the aging of accelerated organs and reduce the risk of illness, he said.
