Telomere (tel-uh-meer) from the Greek telos (end) and meros (part)
Telomeres are an essential part of human cells that affect how our cells age.
Telomeres are the caps at
the end of each strand of DNA that protect our chromosomes, like the plastic
tips at the end of shoelaces.
Without the coating,
shoelaces become frayed until they can no longer do their job, just as without
telomeres, DNA strands become damaged and our cells can’t do their job.3
Telomeres protect the
vital information in our DNA
DNA makes up all of the cells in our body. It is the genetic material that
makes us who we are. And every organ in our body (skin, liver, heart, etc.) is
made up of cells. So, telomeres are vital to our health.
Our cells replenish by
copying themselves. This happens constantly throughout our lives. Telomeres get
shorter each time a cell copies itself, but the important DNA stays intact.4
Eventually, telomeres get
too short to do their job, causing our cells to age and stop functioning
properly. Therefore, telomeres act as the aging clock in every cell.
Telomeres are shortened as we
age, but telomeres can also be shortened by stress, smoking, obesity, lack of
exercise and a poor diet
Short telomeres are
connected to premature cellular
aging.
Telomere shortening is involved in all aspects of the aging process on a
cellular level. Telomere length represents our biological age as opposed
to our chronological age.
Many scientific studies
have shown a strong connection between short telomeres and cellular aging.
For example, the immune
system, which normally weakens as we age, is highly sensitive to shortening of
telomeres. In
addition, a 2007 study found that short telomeres were associated with decreases
in bone mineral density in women.
Without the protection from telomeres, our cells age and die
Scientists know a lot about telomeres, and they continue to find new evidence about the role telomeres play in the aging process on a cellular level
