Pharmacological activation of AMPK using metformin or berberine prevents oxidative stress-induced cellular senescence by restoring autophagic flux and elevating intracellular NAD+ levels.
This research suggests that maintaining cellular energy balance via AMPK activation (through lifestyle or pharmacological means like metformin/berberine) may help cells resist aging-related damage. However, this is based on cell cultures, not humans. Do not self-prescribe metformin or berberine for anti-aging without medical supervision, as the optimal dosing and long-term safety in healthy humans are not established by this study.
pharmacological activation of AMPK by metformin and berberine significantly prevented the development of senescence... AMPK activation prevented hydrogen peroxide-induced impairment of the autophagic flux... AMPK activation restored the NAD+ levels in the senescent cells
Why this rating
The study uses in vitro cell models (NIH3T3, MRC-5, HUVECs) rather than human clinical trials, limiting direct applicability to human health outcomes.
