Scientists increased SIRT6 in mice and found that it preserved youthful chromatin in the liver and, when boosted in elderly animals, reversed many age-related chromatin changes toward a younger state within a month, suggesting some aging effects may be reversible rather than fixed—though these findings are not yet transferable to humans.
Bar-Ilan researchers showed that increasing SIRT6 levels specifically in the liver of 24‑month‑old male mice reversed about 80% of age-related chromatin accessibility changes within one month, with downstream inflammatory and metabolic gene programs moving toward a youthful pattern. The intervention used a hepatocyte-targeted viral vector and yielded tissue- and mechanism-specific reversal, not a universal rejuvenation. While scientifically significant for chromatin dynamics and aging biology, translating this to humans would require substantial further work, safety testing, and validation; the broader implications for human longevity are modest and long-term, not an immediate anti-aging breakthrough.
Israeli scientists have identified a protein called Sirt6 that plays a key role in regulating hydrogen sulfide gas, which is crucial for healthy aging and may lead to new drug development to extend human lifespan and combat age-related diseases.
