Telomeres may hold the secret to providing us with optimal health. Telomere shortening has been identified as the primary cause of human aging and age-related diseases such as cancer, autoimmunity, and heart disease. Telomere Length Analysis is an accurate index of the body’s biological vs chronological age and is a major breakthrough for medicine in addressing chronic diseases and improving longevity.

Telomeres, DNA, And Chromosomes

DNA is the genetic code that contains information for the structuring and functioning of our body. It’s like the hard disk in a computer that contains all the information for the programs that run within a computer. Our DNA is a long thread of the double helix that is packaged in the form of the chromosomes. There are 23 pairs of chromosomes in human cells.

The end parts of the chromosomes are called telomeres. Their name derives from Greek — telos meaning “end” and meros meaning “part”. Telomere ends serve to protect the DNA. They are often compared to the plastic protective tips in shoelaces that protect a shoelace from unravelling. In this same way, telomeres play an important role in protecting the DNA and keeping it stable.

 

Human cells start at conception with an average telomere length of 15.000 base pairs (unit of measurement of telomeres length, abbreviation bps). During the embryonic period we lose a large amount of our telomeres due to the high cellular replication rate. We lose almost as much telomere length as we are going to lose during the whole of our lifetime.

At birth, the average telomere length is 10.000 bps. At 20 years of age the average telomere length is around 8.000 bps. We keep losing 35-150 base pairs per year until we reach a level of less than 4.500 bps. The chromosomes then become unstable and the probabilities for serious health problems and death increase exponentially.

More than the absolute length value, it’s the rate of loss that is important to our health. A person that loses 35 bps instead of 150 bps per year, ages at a five times slower pace. It’s also important to mention that our cells possess inherent mechanisms that repair and can even re-lengthen telomeres.

Multiple factors activate this mechanisms: vitamins, antioxidants, diet, omega 3 fatty acids, exercise, and nutraceuticals have been associated with longer telomere length and telomere re-lengthening.  

Telomeres Relation To Health And Aging Related Diseases

If the telomeres were not there or they were not long enough, the ends of the different chromosomes would fuse together causing the cells to dysfunction or die. When telomeres get too short, the chromosomes ends of different chromosomes fuse together and this has been identified as the starting event of cancer formation (carcinogenesis).

During our lifetime our telomeres get shorter and shorter and this is the basic reason why we age.

With every cell division a small part of our telomeres is not copied and this causes them to gradually shrink. Shorter telomeres cause our DNA to become unstable and prone to express disease.

The shorter our telomeres, the older we become biologically; while the opposite is also true. The longer our telomeres, the younger our cells are biologically; and the better our health.

In 2009 the Nobel Prize in medicine was awarded to three scientists (E. Blackburn, C. Greider, J. Szosak) for their work in telomere biology and the discovery of the mechanisms of aging in humans. In the past it was thought that the way we age was through accumulation of damage at a cellular and organ level. We believed that damages accumulate and our body gets older like a machine wears off. The truth came to be different though in view of the telomere biology discoveries.

We grow old not because of accumulated damage at a cellular level, but mainly because aging is programmed within our DNA. Accumulated biological damage causes our cells to replicate faster and this shortens our telomeres and thus we get older and die. The wear off is not the cause but the accelerating factor in the aging process. This may look similar but it makes a great difference actually in the way we can influence our longevity and health.  

Our cells have a limited amount of divisions available through a lifetime. This number is around 50 times and is regulated through the length of our telomeres. We thus get born with a finite number of cellular divisions at our disposal and the way we live determines how much those cellular divisions are going to last.

If we do things that damage our cells like smoking, not sleeping enough, following bad nutritional habits, suffering vitamins deficiencies, consuming too much alcohol, using drugs, being obese, not exercising, conducting a stressful life, being dehydrated and getting exposed to toxins, we force our cells to divide faster in order to repair damaged tissues and we consequently age faster. In fact all the above factors are correlated to increased incidence of disease and premature death.

Biological Versus Chronological Age

The faster our cells divide the faster our telomeres shrink. The more damage at the cellular level, the more cellular divisions are required.

That easily explains how two individuals can have the same chronological age but be in completely different biological condition.

Telomere length has been found to be an accurate index of the biological versus the chronological age of an individual. The longer our telomeres, the younger our biological age. Shorter telomeres are associated with higher mortality and aging related diseases.

Research suggests that preserving telomeres length has the potential to prevent and treat diseases associated with aging and possibly allow humans to increase their longevity beyond the current theoretical maximum of 125 years.

Telomere Length Measurement

Our cells have 23 pairs of chromosomes. Each pair has four telomeres for a total of 92. Not all telomeres shrink at the same speed though. Some of them shorten faster than others, so some of our telomeres may be long while some of them may be short.

There are two kinds of telomere analysis. One that measures average length and one that measures each single telomere. Telomere analysis that measures only the average length, gives zero data about the percentage of long telomeres, and more importantly, doesn’t reveal the percentage of the short telomeres present in our chromosomes. That’s why it is vital to measure the length of each single telomere in order to assess biological age and chronic disease risk.

An individual could have a good average telomere length but a high percentage of short telomeres that would not show in an average length measurement. His or her DNA could then become unstable because of the shorter telomeres. This increases the possibility for chronic disease and death even in the presence of a good average telomere length.

The percentage of short telomeres in an individual is the most important element needed to evaluate the biological age and propensity to disease.

It is thus vital to measure not just the average length but also the length of each of the 92 telomeres separately. This can be done with a method called HT Q-FISH (High-Throughput Quantitative Fluorescent in Situ Hybridization).

Since 2015, Metabolomic Medicine Health Clinics, in collaboration with the University of Crete Medical School, have been the first and only clinic worldwide to combine the HT-Q-FISH Telomere Analysis with Metabolomics Analysis and treatment. This permits the assessment of both the DNA and the biochemical pathways condition simultaneously.  

We measure all four telomeres in each of the 23 pairs of chromosomes, for a total of 92 telomeres.

Repeated measurements at a distance of six months or a year, reveal vital information about the rate of change of the short telomeres, response to therapy, and the formulation of further treatment.

As the percentage of short telomeres has been associated with almost all chronic diseases, their measurement can be an invaluable tool in the hands of a physician applying personalized medicine. Telomere Length Analysis is a major breakthrough for medicine in addressing chronic diseases and improving longevity.
