At carnivals, some workers claim to predict your age. Usually, they assess age depending on the aspects of appearance, like body posture, wrinkles over the face, etc. Besides, if they fail to guess the correct age, you win some prize. Now scientists have attempted the task of age prediction. A team of researchers from Stanford University School of Medicine need not see you for estimating the age. In its place, they have used a type of physiological clock; it includes the levels of 373 proteins flowing in the blood. Scientists claim that they have recognized some proteins in the blood of humans that increase and decrease in amazing ways as we grow. The findings could offer significant hints regarding which constituents of the blood can slow the pace of aging.
The team of researchers has studied around 3,000 proteins in blood samples taken from more than 4,000 people. Notably, the participants belonged to an age group between 18-95, including both men and women. Prof. Tony Wyss-Coray, from Stanford University, said proteins are like hard workers of the body’s constituent cells. He added, when some crucial changes take place in levels of proteins, it resembles some change in the body too. Coray said, looking at thousands of them in plasma offers a perspective of what’s happening inside the body.
As per the study, published on Thursday in Nature Medicine, these proteins alter in three different waves. The first change takes place very unexpectedly, during the period of 30-34. Coray said they had discovered a second movement around the 60s. After that, the most popular third wave takes place around the 80s. Although, the study has raised a series of questions regarding the bioscience of aging. Coray noted that most of the proteins in the bloodstream belong to other tissues. So they might begin from the question- what is the source of proteins and whether they change with age. In the end, Coray said they would like to match a person’s blood protein pattern with the normal protein pattern. As a result, it will lead to a modified aging clock, which will reveal the speed of the aging process.
