Betulin Protects Against Cardiac Hypertrophy by Improving AMPK/Nrf2‐Dependent Mitochondrial Function

Phytotherapy Research, Volume 40, Issue 5, Page 2878-2894, May 2026.
Betulin effectively mitigates pressure overload‐induced cardiac hypertrophy in both Ang II‐infused and TAC‐operated mice. Mechanistically, betulin activated AMPK phosphorylation, promoted Nrf2 nuclear translocation, and upregulated antioxidant genes (HO‐1 and NQO‐1), thereby restoring mitochondrial function in cardiomyocytes.
