Dr Bill Andrews' Lecture in Tokyo: Unlocking the Future of Ageing and Telomere Science

In the fascinating world of ageing research, few voices resonate as strongly as Dr Bill Andrews, a pioneering telomere biologist and founder of Sierra Sciences. His groundbreaking work on telomeres and telomerase has opened an exciting frontier that promises to revolutionise how we understand and potentially cure human aging. Delivered in Tokyo, this comprehensive lecture covers decades of research, breakthroughs, and the future possibilities of extending human health-span and lifespan through telomere manipulation.

In this article, we will explore Dr Andrews’ insights into the biology of ageing, the crucial role of telomeres, the challenges posed by demographic shifts such as Japan’s “silver tsunami,” and the revolutionary potential of gene therapy aimed at telomere lengthening. We will also delve into the controversies surrounding telomerase and cancer, clarifying common misconceptions, and highlighting the remarkable evidence supporting telomere extension as a pathway to improved health and longevity.

Understanding Ageing: More Than Just Growing Old

Ageing is often casually accepted as a natural, inevitable process—something to be endured with grace, enjoying retirement or time with grandchildren. However, Dr Andrews challenges this simplistic view by emphasising the harsh realities many elderly individuals face: suffering in nursing homes, assisted living, or hospices, unable to care for themselves and burdened by disease.

He stresses that ageing is, in fact, the most devastating disease humanity has ever encountered. It is responsible for the majority of deaths worldwide, accounting for an estimated 150,000 deaths every day. The significance of this cannot be overstated: if the ageing process were solved, half of the current population could theoretically live for a thousand years, barring accidents or other external causes.

Dr Andrews’ personal motivation for this research stems from his own father, who inspired him at the age of ten by urging him to become a doctor and find a cure for ageing. This deeply personal connection fuels his lifelong commitment to understanding and combating the biological mechanisms behind ageing.

The Silver Tsunami: A Demographic Crisis and a Call to Action

One of the pressing issues Dr Andrews highlights is the demographic challenge facing Japan and other East Asian countries, which he terms the “silver tsunami.” By 2050, it is projected that 40% of Japan’s population will be over 65 years old, an unprecedented proportion globally.

This shift presents a severe social and economic challenge, as the ratio of working-age individuals to elderly dependants will plummet to almost 1:1. The implications for care-giving, healthcare costs, and financial sustainability are enormous. South Korea and China face similar, though slightly less severe, demographic trends.

Dr Andrews argues that the solution is not merely to manage this ageing population but to fundamentally change the ageing process itself. Instead of allowing people to become frail and dependent, the goal should be to keep people young, healthy, and productive well into advanced age. This vision places telomere biology at the centre of future strategies for extending health-span and mitigating the societal impacts of ageing.

Telomeres: The Biological "Ride Tickets" of Life

To understand how ageing occurs on a cellular level, Dr Andrews introduces the concept of telomeres. Telomeres are protective caps located at the ends of chromosomes, akin to the plastic tips on shoelaces that prevent fraying. These structures play a vital role in maintaining the integrity of our DNA during cell division.

Every time a cell divides, its telomeres shorten slightly. This shortening acts as a biological clock or “ride ticket” system, counting down the number of times a cell can divide before it becomes dysfunctional or dies. At conception, telomeres measure approximately 15,000 bases in length; by birth, they shorten to about 10,000 bases; and by the time of death, they shrink to around 5,000 bases.

This progressive shortening is a major driver of ageing and age-related diseases. When telomeres become critically short, cells lose their ability to function properly, leading to tissue degeneration and the onset of diseases commonly associated with ageing.

Dr Andrews highlights a seminal discovery from 1961, known as the Hayflick Limit, which demonstrated that human cells grown in culture can only divide a finite number of times before ceasing to proliferate. This limit varies with age: cells from younger individuals divide more times than those from older individuals, reflecting their longer telomeres.

The Tug of War: Telomere Shortening vs. Lengthening

Dr Andrews describes telomere dynamics as a tug of war between forces that shorten telomeres and those that lengthen them. Unfortunately, in most human cells, the shortening forces dominate because the enzyme responsible for telomere extension, telomerase, is inactive outside of reproductive cells.

While lifestyle factors such as exercise, diet, stress reduction, and avoiding smoking can reduce the rate of telomere shortening, they cannot stop it entirely. Even with optimal health behaviours, telomeres will continue to shorten over time, leading to inevitable ageing.

The ultimate goal, therefore, is to shift this tug of war towards balance or even favour the lengthening side. This is where telomerase comes into play.

Telomerase: The Enzyme That Holds the Key to Longevity

Telomerase is a unique enzyme that adds DNA sequence repeats to the ends of telomeres, effectively rebuilding their length and resetting the cellular “clock.” It is naturally active in primordial germ cells—those that give rise to sperm and eggs—ensuring that offspring start life with full-length telomeres.

However, in most adult somatic cells, telomerase is turned off, resulting in progressive telomere shortening with each cell division. This evolutionary mechanism likely developed as a pro-death system to eliminate old individuals and promote genetic diversity through the reproduction of younger generations.

Dr Andrews and his team have focused their research on finding ways to reactivate telomerase in adult cells without causing harm, aiming to extend healthy lifespan by maintaining or lengthening telomeres.

Dispelling the Myth: Does Telomerase Cause Cancer?

One of the most contentious topics in telomere biology is the relationship between telomerase and cancer. A common misconception, perpetuated by some prominent scientists, is that telomerase activation causes cancer. Dr Andrews vigorously disputes this claim, presenting extensive evidence to the contrary.

He explains that cancer is fundamentally caused by genetic mutations, not telomerase activity. In fact, short telomeres are more often associated with increased cancer risk because critically short telomeres can lead to chromosomal instability and mutations.

Dr Andrews highlights that telomerase is present in cancer cells because it allows them to divide indefinitely. However, this presence is a result of cancer rather than its cause. Importantly, his research demonstrated that inhibiting telomerase in cancer cells kills them, while activating telomerase in normal cells extends their lifespan without causing cancerous behaviour.

He also addresses recent genome-wide association studies (GWAS) that link certain genetic variants associated with longer telomeres to increased cancer risk. Dr Andrews clarifies that these studies do not show causation between long telomeres and cancer but rather that the genetic variants influence both traits independently.

Evidence from Nature: Long-Lived Animals with Active Telomerase

Supporting Dr Andrews’ position are remarkable examples from the animal kingdom. Species such as lobsters, clams, tortoises, humpback whales, and certain birds exhibit active telomerase in all their cells and show negligible signs of ageing or cancer.

For instance, lobsters produce telomerase throughout their bodies and can live over 100 years without significant ageing or cancer incidence. Similarly, the Galápagos tortoise “Harriet” lived to 180 years old, maintaining health until her death from a viral infection rather than ageing.

These examples demonstrate that sustained telomerase activity and long telomeres do not inevitably lead to cancer, challenging the prevailing fears and opening new avenues for human therapies.

From Discovery to Therapy: The Journey of Telomerase Research

Dr Andrews recounts the history of telomere and telomerase research, highlighting key milestones:

• 1961: Leonard Hayflick discovers the finite division capacity of human cells (Hayflick Limit).

• 1971: Telomere shortening is proposed as a mechanism of cellular ageing.

• 1984: Elizabeth Blackburn and Carol Greider discover telomerase in the single-celled organism Tetrahymena.

• 1992: Dr Calvin Harley proposes the telomere hypothesis of ageing.

• Early 1990s: Dr Andrews’ team discovers human telomerase and demonstrates its role in extending the Hayflick limit.

• Recent years: Gene therapy experiments in mice reverse ageing symptoms by lengthening telomeres.

This timeline underscores the evolution of understanding from basic science to potential clinical applications, driven by decades of tireless research.

Gene Therapy and Telomerase Activation: A New Horizon

One of the most exciting developments in Dr Andrews’ work is the advancement of gene therapy techniques aimed at delivering the telomerase gene directly into human cells. This approach involves packaging the telomerase gene inside tiny lipid “soap bubbles” that can fuse with cells and introduce the gene, prompting them to produce telomerase and lengthen their telomeres.

Dr Andrews reveals that his company, Sierra Sciences, has identified a potent chemical activator called TAM 818, which can stimulate telomerase activity up to 300 times more effectively than other compounds. While this molecule slows telomere shortening, gene therapy offers the potential to reverse telomere shortening altogether.

Plans to begin human trials of telomerase gene therapy were underway as early as December 2017, marking a significant step towards translating research into real-world treatments.

Scientific Validation: Reversing Ageing and Extending Lifespan

Research conducted by colleagues such as Dr Ron DePinho has shown that reactivating telomerase in aged mice engineered to mimic human ageing results in remarkable rejuvenation:

• Reversal of age-related tissue degeneration.

• Restoration of fertility.

• Improved brain size and function.

• Increased lifespan by up to 30%.

• Visible improvements in coat health and vitality.

These findings have been widely reported in the media and scientific literature, providing proof of concept that telomere extension can reverse key aspects of ageing.

Telomeres as the "Kingpin" of Ageing: Unifying Ageing Theories

Beyond telomere shortening, ageing theories include mitochondrial dysfunction and oxidative stress. Dr Andrews highlights that telomere length appears to influence these pathways as well, suggesting a unifying role for telomeres in the ageing process.

By maintaining telomere length, it may be possible to mitigate multiple ageing mechanisms simultaneously, offering a comprehensive approach to lifespan extension unmatched by other interventions such as NAD boosters or antioxidants.

Practical Steps Today: Lifestyle and Telomere Health

While the promise of gene therapy and telomerase activation is on the horizon, Dr Andrews emphasises the importance of lifestyle choices that can slow telomere shortening:

• Regular exercise, especially endurance activities.

• A balanced diet rich in antioxidants and omega-3 fatty acids.

• Avoiding smoking and obesity.

• Managing stress and maintaining a positive outlook.

• Ensuring adequate vitamin D levels.

These measures, supported by research such as the book The Telomere Effect by Elizabeth Blackburn and Lisa Epel, can help preserve telomere length and improve health-span while more advanced therapies are developed.

Conclusion: Toward a Future Where Ageing Can Be Cured

Dr Bill Andrews’ lecture in Tokyo offers a profound look into the science of telomeres and telomerase, revealing a path toward potentially curing human ageing. His decades of research have uncovered the molecular mechanisms driving cellular ageing and demonstrated that telomere lengthening is not only possible but may be the most effective way to extend healthy lifespan.

While challenges remain, including overcoming misconceptions about telomerase and cancer, the evidence is mounting that telomere biology holds the key to a healthier, longer life. With gene therapy trials on the horizon and powerful telomerase activators under development, the dream of halting or even reversing ageing may soon become a reality.

For those interested in delving deeper, Dr Andrews has authored two books—Curing Ageing and Telomere Lengthening—and recommends the documentary The Immortalist for a compelling overview of this transformative field.

The future of ageing research is bright, and with continued scientific innovation, we may soon witness a world where age-related diseases are a thing of the past, and longevity is limited only by our imagination. Meanwhile Dr Bill Andrews has created a completely natural supplement proven to significantly increase Telomerase.
