Biology of Immortality: Telomeres and Telomerase

Telomeres and Cell Lifespan

• Telomeres shorten with each cell division, leading to cell senescence and death.

Telomerase and Its Implications

• Telomerase is an enzyme that can prevent telomere shortening and potentially extend cell life.
• Cancer cells use telomerase to achieve immortality, highlighting the potential dangers of manipulating telomeres.
• Further research into telomerase and its side effects is crucial for potential applications in extending lifespan.

Caloric Restriction and Longevity

• Caloric restriction is a proven method for extending lifespan in various organisms.
• Reducing calorie intake by 30% can increase lifespan by roughly 30%, regardless of species.
• Extensive research supports the potential benefits of caloric restriction for longevity.

Importance of Research

• Scientific research is essential for understanding the complex mechanisms of aging.
• Exploring potential solutions for extending lifespan requires careful consideration of both benefits and risks associated with manipulating cellular processes to achieve immortality.
