How To Live Longer: Exploring Telomerase and Aging about Genesis

It's no secret that some folks age better than others. Is it luck of the draw or genetics? Turns out there's a single enzyme that may hold the key to unlocking the secrets of longevity.

The significance of the enzyme telomerase was first discovered by scientists who went on to win the Nobel Prize in 2009. Since then, scientists have continued to explore its role in aging and age-related diseases.

In this blog post, we dive deep into the world of telomerase and its relationship with aging. We'll focus on the latest research, potential therapeutic approaches, and lifestyle factors that can influence your body's telomerase activity and positively-- or negatively-- impact your own aging process.

Think of this as your ultimate guide to an influential enzyme that can help you remain young in body and mind for years to come. Read on as we unravel the intricate relationship between telomerase and aging, and explore the molecular mechanisms behind cellular senescence.

What's more, we'll cover the impact of telomere dysfunction and telomere shortening on age-related diseases and the potential benefits of targeting telomerase in the quest for a longer, healthier life.

Key Takeaways

  • The loss of telomeres and telomerase are believed to be a key driving of aging and illness.

  • Telomerase plays a vital role in telomere length.

  • Lifestyle factors such as diet, exercise, stress management and supplementation can influence telomerase activity, telomere length and slow the aging process.

  • Therapeutic approaches targeting telomerase have the potential to treat age-related diseases by activating or inhibiting telomerase function.

The Telomere Theory of Aging

Telomeres are the protective endcaps at the ends of your chromosomes. They're like a shield of armor that protect the DNA inside when your cells divide.

When human cells divide, the DNA is unrolled like a sheet of wrapping paper and copied. Trouble is, with the way human cells divide, the very end of the cell-- where the telomeres are located-- can't be copied and some of the telomere is lost with each cellular division.

Telomeres shorten until they are gone. At that point, the cell can no longer replicate itself and has entered cellular senescence, a state of irreversible cell cycle arrest and death.

Most cells divide 50 times before the telomeres are gone and the cells are old and no longer functional. But there are some cells in your body that need to divide many more times than 50. These cells include stem cells, sperm cells and white blood cells, for example.

Those cells make an enzyme called telomerase that rebuilds the telomere shell of armor and maintains telomere length despite cellular division.

Researchers believe that the loss of telomeres and telomerase is a key driver of aging and illness. They point to studies that show how older people who are suffering diseases of aging have shorter telomeres. And older people who remain healthy and long-lived have longer telomeres including some 100-year-old folks who have telomeres that are of similar length to individuals in middle age. In fact, some of these centenarians have telomeres that have even grown longer.

Scientists believe their secret is telomerase.

Telomere Length, Telomerase and Aging

The telomerase enzyme has a mighty important job in human cells.

This hard-working enzyme maintains telomere length, protecting the caps at the ends of chromosomes. As all of your cells, including muscle cells, divide and age, their telomeres gradually shorten, eventually become senescent-- or old and dysfunctional. This natural process is believed to contribute to aging and the development of age-related diseases.

But what if we could intervene in this process and slow down or even reverse the effects of aging? In the following sections, we will explore:

  • The function of telomerase and its role in cellular senescence
  • The potential benefits of telomerase activation for lifespan extension

  • The link between telomere dysfunction and age-related diseases such as cardiovascular, neurodegenerative, and metabolic disorders.

Inside Human Cells: The Function of Telomerase

Telomeres critical structures are maintained by telomere binding proteins and the enzyme telomerase. Telomerase adds repetitive DNA sequences to the ends of chromosomes, ensuring their stability and safeguarding our genetic information from harm.

As cells divide, their telomeres naturally shorten, which is believed to be an indicator of lifespan rather than average telomere length alone. In certain abnormal circumstances, such as in cancer cells and immortalized cell lines, an alternative mechanism called ALT (Alternative Lengthening of Telomeres) is employed to maintain telomere length. This mechanism is not found in normal cells.

As we've reported in the past, the delicate balance between telomere shortening and extension is crucial for maintaining genetic stability and preventing premature aging. When telomeres become critically short, cells enter a state of replicative senescence, losing their ability to divide and function properly.

Understanding the function and regulation of telomerase is essential for developing potential therapies targeting telomere maintenance, telomere length and human aging.

Cellular Senescence and Aging

As we've written about before, cellular senescence is a state of irreversible cell cycle arrest, which is linked to telomere shortening and contributes to aging and age-related diseases. The role of telomeres in premature aging disorders is not yet completely understood. However, telomere dysfunction is believed to contribute to replicative senescence in somatic cells, potentially through an impact on cell division. In other words, normal human cells can become abnormal and malignant cells.

The impact of telomere shortening on fertility is worth noting. Scientists have observed shorter leukocyte telomere length in women undergoing in vitro fertilization and shorter telomeres found in human oocytes (or eggs) and polar bodies (new cells in a healthy, growing egg).

What's more, in patients with a variety of illnesses telomere length can indicate the severity of their illness and even how well they'll recover. This has been documented in patients with aplastic anemia. Those with shorter telomeres in their peripheral blood mononuclear cells (a type of blood cells) at diagnosis demonstrate more severe illness, poorer response to treatments, increased risk of recurrence, as well as reduced survival rates.

The rate of telomere loss varies throughout a human lifetime. Interestingly, there is a much greater los of telomeres observed during the first two years of life than during later life, particularly in the loss of stem cells.

Research shows that telomeres in stem cells from human umbilical cord blood are longer than those extracted from adult bone marrow. Telomere loss in stem cells is rapid within the first year of life, continues to decline until 50 to 60 years of age, and is exaggerated beyond the age of 70.

This simple medical fact drives home the importance of understanding the link between telomere shortening, cellular senescence, and aging in order to develop potential therapies targeting improved telomere length. And that's where this powerful enzyme telomerase comes in.

Telomerase Activation and Longer Life

Research has demonstrated that activation of telomerase can extend the lifespan of certain organisms and delay the emergence of age-related diseases, providing a potential avenue for therapeutic intervention. This exciting discovery raises the possibility of harnessing the power of telomerase to combat aging and improve health-span and lifespan.

We'll talk about this more in a minute, but there are a number of lifestyle choices you can make that can support telomerase activity and maintain telomere length. For instance, telomere length has been found to increase with a diet rich in fiber. On the other hand, a higher intake of polyunsaturated fatty acids (think omega-6s found in vegetable oils and processed foods) along with a bigger waist circumference have been known to reduce telomere length.

By deepening our understanding of the complex relationship between telomerase activation, telomere maintenance, telomere length and aging, we may be able to unlock new ways to foster healthy longevity and combat age-related diseases. This could have far-reaching implications for the future of aging research.

Age-Related Diseases and Telomerase Dysfunction

Telomerase dysfunction is linked to a wide range of age-related diseases, including cardiovascular, neurodegenerative (like Alzheimer's disease and Parkinson's disease), and metabolic disorders. By exploring the complex relationship between telomerase activity and the onset of these diseases, we may be able to develop strategies to prevent or treat these conditions and improve overall health and longevity.

Read on as we delve into the link between telomerase dysfunction and various age-related diseases. Then we'll explore how telomere dysfunction contributes to the onset and progression of cardiovascular, neurodegenerative, and metabolic disorders.

Cardiovascular Diseases

Cardiovascular diseases are a leading cause of death worldwide, and emerging evidence suggests that telomere dysfunction may play a key role in their development. Scientists have found that shortened telomeres are potential indicators of cardiovascular disease.

How can comprehending the complex relationship between telomere dysfunction and cardiovascular disease help? Importantly, it means scientists will get closer to developing effective therapies to prevent or treat these conditions and improve overall heart health. And that's a win for us all.

The potential benefits of targeting telomerase activity in the context of cardiovascular diseases are vast, ranging from slowing the progression of heart disease to improving the efficacy of existing therapies to strengthen the heart, blood vessels and the lungs.

Neurodegenerative Diseases

Neurodegenerative diseases, such as:

  • Alzheimer’s disease
  • Parkinson’s disease

  • Huntington’s disease

  • Amyotrophic lateral sclerosis (ALS)


What do these diseases have in common? They are all characterized by the progressive loss of neurons and their connections within the nervous system. Now there's growing evidence suggesting that telomere dysfunction may contribute to the development of these devastating age-related diseases.

What's the main culprit? lt's likely the accumulation of senescent cells and chronic inflammation, which we've written about in the past.

Researchers believe that by preserving telomere length and reducing the accumulation of senescent cells, it may be possible to slow the progression of neurodegenerative diseases and improve the quality of life for millions of people around the world.

What's more, as our understanding of this complex relationship deepens, we may be able to better prevent or treat neurodegenerative diseases and improve overall brain health.

Metabolic Diseases and High Blood Sugar

Metabolic diseases, such as Type-2 Diabetes and metabolic syndrome, are characterized by the body’s inability to effectively convert food into energy. Telomere dysfunction has been implicated in the development of these diseases, with research suggesting that it may impact cellular senescence and cause disease progression.

For example, in the context of Type-2 Diabetes, scientists discovered that mice with short telomeres also showed impaired insulin secretion and glucose intolerance. Furthermore, metabolic syndrome, a cluster of conditions including obesity, high blood pressure, and insulin resistance, has been linked to telomere dysfunction and an increased risk of cardiovascular disease. As we've written about before, rates of metabolic syndrome are skyrocketing in the U.S. and around the globe.

By preserving telomere length and reducing cellular senescence, it may be possible to slow the progression of metabolic diseases and improve overall health and well-being.

Lifestyle Factors Influencing Telomerase Activity and Aging

The choices we make in our daily lives can have a profound impact on our telomeres, and by extension, the aging process. Factors such as diet, exercise, and stress management can all influence telomerase activity and the rate of telomere shortening. It's no wonder that we write regularly about these healthy lifestyle habits!

In the following sections, we shed some light on the potential benefits of adopting a healthy lifestyle for maintaining optimal telomere health.

Diet and Nutrition

As we mentioned earlier, science shows that eating a healthy diet rich in fiber can have a significant impact on telomere length and the rate of telomere shortening.

What's more, research has shown that a diet enriched with omega-3 fatty acids-- such as the Mediterranean Diet-- is linked to a slower rate of telomere shortening, while a deficiency of these fatty acids is associated with a faster rate of telomere loss.

Antioxidants are also important. Antioxidants can help protect telomeric DNA from oxidative damage caused by both external and internal factors, such as exposure to environmental toxins and the natural byproducts of cellular metabolism.

In addition, there are a number of other dietary factors to consider to reduce the rate of telomere shortening. For example:

  1. Consume polyphenols: Certain powerful antioxidant compounds called polyphenols are found in foods like green tea, red wine, berries, and dark chocolate. They've been associated with anti-aging benefits. Researchers believe this may contribute to human cell health and impact telomere length, ultimately slowing cellular senescence.

  2. Increase intake of antioxidant vitamins and minerals: Adequate intake of essential vitamins and minerals, such as vitamin C, vitamin E, selenium, and zinc, through a balanced diet is important for overall health and is believed to indirectly influence telomere length by supporting the function of human cells.

  3. Consider occasional fasting or caloric restriction: Some research in animals suggests that caloric restriction, or consuming fewer calories while maintaining proper nutrition, might have positive effects on telomere length and longevity in people. We've written before about fasting and caloric restriction and its connection to human longevity.

  4. Consumer a plant-based diet: Some studies suggest that individuals following a predominantly plant-based diet, such as a Mediterranean diet or a diet rich in fruits and vegetables, may have better telomere length and avoid an increase in telomere shortening that happens with age. We've written about the longevity benefits of an anti-inflammatory, telomere length-boosting Mediterranean diet in the past.

  5. Avoid processed foods: Diets high in processed foods, sugary snacks, and unhealthy fats might contribute to inflammation and oxidative stress, potentially impacting telomere length and contributing to cellular senescence.


If you're interested in optimizing your diet for potential anti-aging benefits, it's recommended to focus on eating well-balanced meals that include a variety of nutrient-rich foods. By incorporating foods that are plant based and rich in antioxidants and fiber, you may be able to maintain telomere length, slow cellular senescence and slow the aging process.

Exercise and Physical Activity

We know and have reported before how exercise offers a plethora of benefits including cardiovascular, brain health, weight management, and more. Well, you can add one more huge benefit to that list: longevity. That's right, researchers have discovered that regular exercise has a protective effect on telomeres, reducing oxidative stress and slowing the aging process.

By engaging in regular physical activity, we can minimize oxidative damage to our telomeres and promote overall health and vitality. In addition to reducing oxidative stress, regular exercise has been shown to inhibit the aging process by preserving telomere length and slowing the rate of telomere shortening.

Incorporating regular exercise into our days can support our telomeres and slow the aging process, promoting a longer, healthier life.

Stress Management

Effective stress management is also crucial for maintaining telomere length and reducing the pace of aging. By minimizing oxidative damage and inflammation, stress management can help preserve telomere length and slow the aging process. Various relaxation techniques that can help manage stress levels and support telomere health include:

  • Deep breathing

  • Meditation

  • Yoga

  • Tai chi


We investigated the benefits of meditation before. We reported on fascinating research that linked chronic stress to shorter telomeres and less active telomerase, the enzyme that can re-lengthen telomeres.

Researchers wanted to find out if meditation had positive effects on the markers of aging so they enrolled 30 participants to participate in a three-month meditation retreat. It turned out that besides experiencing greater emotional well-being, the meditators exhibited 30 percent more telomerase than the control group!

The importance of stress management in maintaining telomere length cannot be overstated. By adopting effective stress management techniques, we can not only support our overall health and well-being but also help preserve our telomeres and slow the aging process.

Supplements for Telomere Support

As we mentioned, antioxidants, plant-based compounds and fatty acids can go a long way towards helping your telomere length as you age. But you can do even more.

Green Valley Natural Solutions created Genesis to support your telomere health. It starts with a patented nutrient called Telos95, shown in a recent study at Princeton Consumer Research to support telomere health.

Genesis also contains a clinical dose of cycloastragenol, an extract of Astragalus-- an herb that has been used for centuries in traditional Chinese medicine and is shown to support telomere health.

Finally, Genesis also contains the antioxidant support of alpha lipoic acid and Vitamin D3 and K2, a powerful combination shown in clinical studies to support your DNA's "power plant," mitochondria.

Therapeutic Approaches Targeting Telomerase

By understanding the complex relationship between telomerase and aging, as well as developing safe and effective therapies targeting telomerase, scientists may discover new ways to combat age-related diseases.

In the following sections, we will explore:

  1. The potential benefits of telomerase activation
  2. The role of telomerase inhibition in cancer treatment

  3. The challenges and future perspectives in developing therapies targeting telomerase.

Telomerase Activation

Telomerase activation has been proposed as a potential therapy for age-related diseases. Ectopic telomerase expression, a form of gene expression, has been suggested as a potential therapeutic approach for:

  • Extending the life span of human cells;

  • Enhancing the health of donor tissue and organs or even engineered tissue for transplantation;

  • Specific T-cell immunotherapy protocols, in which specific T cells recognizing specific antigens can be purified, expanded in vitro, and infused into patients suffering from a variety of illnesses.


The potential benefits of telomerase activation as a therapy for age-related diseases are vast, ranging from slowing the progression of the disease to improving the efficacy of existing therapies. More research is needed to fully understand this complex relationship.

Telomerase and Cancer

In normal healthy cells, telomerase activity is typically low or absent in most adult tissues. This serves as a natural mechanism to prevent uncontrolled cell growth and the potential development of cancer. In cancer cells, however, there is often reactivation of telomerase, which enables the cells to maintain their telomere length despite rapid divisions. This is one of the factors that contribute to the unlimited growth potential of cancer cells.

Here's how telomerase is related to cancer cells:

  1. Telomere Maintenance in Cancer Cells: Many cancer cells exhibit high levels of telomerase activity, allowing them to maintain their telomeres and continue dividing without undergoing senescence (cellular aging) or apoptosis (cell death). This characteristic enables cancer cells to evade the normal limitations on cell growth.

  2. Immortality of Cancer Cells: The ability of cancer cells to maintain their telomeres through telomerase activation contributes to their immortality and uncontrolled growth. This is one of the hallmarks of cancer and a factor that makes cancer cells difficult to control and eradicate.

It's important to note that not all cancers rely solely on telomerase for maintaining telomere length. Some cancer cells use alternative mechanisms, as we mentioned earlier, such as a process called alternative lengthening of telomeres (ALT), to achieve telomere maintenance.

Inhibition of Telomerase in Cancer Treatment

Due to its role in cancer cell survival and growth, telomerase is being explored as a potential target for cancer therapy. Inhibiting telomerase activity could theoretically slow down or stop the growth of cancer cells. However, developing effective and specific telomerase inhibitors that target cancer cells while sparing normal cells has proven to be challenging. By reducing telomerase activity in cancer cells, it may be possible to:

  • Induce cancer cell death

  • Reduce cancer cell viability

  • Ultimately inhibit tumor growth

  • Improve patient treatment, recovery and longterm survival.


What's more, telomerase activity can sometimes be used as a diagnostic marker for certain types of cancer. Elevated telomerase activity in certain bodily fluids or tissues might indicate the presence of cancer.

The potential benefits of targeting telomerase activity in cancer diagnosis, prevention and treatment are vast, and continued research in this area holds great promise for the future of cancer therapies.

Future Perspectives and Challenges

Future research should focus on understanding the complex relationship between telomerase and aging, as well as developing safe and effective therapies targeting telomerase. By deepening our understanding of how telomerase activity influences the aging process and contributes to the development of age-related diseases, we may be able to unlock new therapeutic strategies to extend healthspan and improve overall health and well-being.

One of the major challenges in developing therapies targeting telomerase is understanding potential side effects of such therapies.

As our understanding of the complex relationship between telomerase and aging deepens, we may be able to develop innovative therapies to:

  • Prevent or treat age-related diseases

  • Improve overall health and well-being

  • Extend healthspan

  • Combat age-related diseases


By harnessing the power of telomerase, we may one day unlock new ways to achieve these goals.

Summary

In conclusion, the enzyme telomerase plays a crucial role in maintaining telomere length and contributing to the aging process. By understanding the complex relationship between telomerase and aging, as well as the impact of lifestyle factors such as diet, exercise, and stress management on telomerase activity, we may be able to develop novel therapeutic strategies to extend health span and combat age-related diseases.

Frequently Asked Questions

How does telomerase affect aging?

Telomerase is an enzyme that helps maintain telomere length in our cells, thereby preventing accelerated aging. It counteracts telomere shortening by adding bases to the ends of telomeres, allowing for repeated cell division without these cells becoming senescent.

Shortening of telomeres to a critically short length can serve as a signal for cellular aging and destabilization of chromosomes which results in a host of age-related diseases.

Can telomerase reverse aging?

Telomerase has been known to offset cellular aging by increasing telomere length, which can add time to your molecular clock so to speak and effectively extend the lifespan of human cells.

Therefore, telomerase has the potential to slow, stop, or even reverse the effects of aging.

What is the telomere theory of aging?

The telomere theory of aging proposes that the telomerase enzyme is responsible for telomere shortening over time, leading to cellular senescence and destabilization of chromosomes, aging and illness.

How can I increase my telomerase naturally?

Regular physical activity, maintaining a healthy weight, quitting smoking, getting enough sleep and reducing and managing stress are good starting points.

Additionally, eating foods high in vitamins, polyphenols, and anthocyanins (such as legumes, nuts, seaweed, fruits, dairy products, and coffee) are all ways to naturally increase your telomerase activity. Taking certain supplements that are shown in scientific research to support telomere health can also help.

These activities can help to protect your telomeres from damage and keep them healthy, which can help slow down the aging process.

How do lifestyle factors such as diet and exercise influence telomerase activity?

Maintaining a healthy diet, exercising regularly, and managing stress are key lifestyle components that can support telomerase activity by supporting cellular health. As a result, they help you preserve telomere length and slow the rate of telomere shortening.
