Can Our Genes Help Us Live Longer?
Modern science is getting closer to answering one of humanity’s oldest questions: why do some people live significantly longer and healthier lives than others? The answer, it turns out, may lie in a handful of powerful genes linked to cellular repair, inflammation control, and metabolic efficiency.
🧠 FOXO3: The “Longevity Gene”
One of the most well-documented longevity-associated genes is FOXO3.
A specific variant, rs2802292, has been repeatedly linked to increased lifespan, slower telomere shortening, and protection from age-related diseases — especially in individuals over 55.
A 2024 study in Nature Aging confirmed that this variant reduces inflammation and even lessens the neurological impact of high blood pressure.

🔬 SIRT1: Master Regulator of Cellular Aging
SIRT1, part of the sirtuin family, plays a vital role in DNA repair, metabolism, and stress resistance.
It has been called “the anti-aging gene” for its ability to promote longevity in animal models. Studies show that activating SIRT1 can mimic the effects of calorie restriction, one of the most consistent life-extending interventions in science.
Compounds like resveratrol (found in red wine) have been shown to activate SIRT1 and are being explored in longevity trials.

🧬 Other Genes Linked to Centenarian Health
In addition to FOXO3 and SIRT1, researchers have found several other genes enriched in long-lived populations, including PCNX2, RGP1, and ANO9.
A 2024 paper in Nature Communications revealed that these genes may enhance cardiovascular function, cognitive resilience, and immune response.
Even more fascinating: a study of cognitively sharp centenarians found that they carry fewer harmful mutations than the general population — a potential protective genetic signature.

🧪 Real-Life Impact: The Case of the Spanish Supercentenarian
In 2025, researchers sequenced the DNA and microbiome of Maria Branyas Morera, the world’s oldest living woman (117 years old). Her biological age was estimated at 17 years younger than her actual age. Surprisingly, her gut microbiota resembled that of a baby, highlighting the powerful intersection of genetics and lifestyle in aging.
