Insights

Aging is a quasi-program, not damage, driven by Target of Rapamycin (TOR). Sirolimus (rapamycin) shows potential as an anti-aging drug, prolonging lifespan and improving healthspan by slowing aging processes.

Area of Science:

  • Gerontology and molecular biology
  • Cellular aging mechanisms
  • Pharmacological interventions for aging

Background:

  • The concept of aging as a quasi-program, not solely molecular damage, was proposed in 2006.
  • Target of Rapamycin (TOR) pathway identified as a key driver of this aging process.
  • Sirolimus (rapamycin) emerged as a potential therapeutic agent based on this concept.

Purpose of the Study:

  • To evaluate the evidence supporting rapamycin as an anti-aging drug.
  • To assess the confirmation of predictions stemming from the quasi-program aging theory.
  • To discuss the future role of rapamycin in anti-aging therapy.

Main Methods:

  • Review and analysis of existing scientific literature and clinical data.
  • Examination of studies investigating rapamycin's effects on aging in various model organisms and cell types.
  • Assessment of rapamycin's impact on lifespan, healthspan, immunity, and stem cell function.

Main Results:

  • Multiple predictions of the quasi-program aging theory have been experimentally confirmed.
  • Rapamycin has demonstrated efficacy in suppressing aging in mammalian cells.
  • Studies show rapamycin prolongs lifespan in model organisms and improves health in aged animals.

Conclusions:

  • The quasi-program theory of aging is increasingly supported by scientific evidence.
  • Rapamycin's multifaceted effects confirm its potential as a significant anti-aging intervention.
  • Rapamycin is poised to become a central therapy for age-related diseases and longevity.

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...
