For many years, researchers at Lund University in Sweden have been working on the analysis of the mechanism of aging in the body. Now researchers are studying the birth of a bird to see if the length of the telomere at birth will affect its late aging. process.

The genetic composition of our body cells includes many genes arranged on the chromosome, and the terminal part of the chromosome is called telomere, which protects the chromosome from damage and mutual adsorption; the longer the telomere, the longer the chromosome maintenance function, and vice versa. The shorter the telomere, the shorter the time it takes for the chromosome to function; therefore, more and more studies have focused on telomeres in recent years to reveal their effects on the aging process in humans and other animals.

In this study, the researchers observed that the telomere length of new born individuals would vary greatly, so they conducted relevant studies to explain the cause of this phenomenon; Dr. Asghar Muhammad said that in the early days of individual life, There is a significant difference in the length of telomeres between individuals such as humans and animals.

The researchers used a 30-year study of the giant salamander living in Kvismaren Lake, southern Sweden, and studied the data to find out which genetic factors affect the length of their telomeres, based on a series of measurements. The researchers compared the telomere length of the newly born individuals and their parents at their infancy. The results showed that the telomere length of the larvae of the cockroaches depends on the genetic and non-genetic factors that are fairly evenly distributed. The older the female is, the longer the telomere of the young cub will be. For example, females can affect the levels of antibodies or hormones in the yolk, which may then affect the telomere length after 10 days of cubs and make it rapid. Shortened.

The researchers said that the effects of telomeres in humans and giant salamanders may not be the same. Previous studies have shown that non-hereditary factors that have significant effects on telomeres in human offspring are related to fathers, not mothers; and finally Asghar Muhammad said that in the human population, there is a certain correlation between the age of the father and the telomere length of the child's body. The older the father, the longer the telomere of the offspring.
