To further elucidate the role of Zfp36 in cardiac hypertrophy and ferroptosis, AAV9 vectors carrying short hairpin RNA targeting Zfp36 (AAV9‐sh‐Zfp36), driven by the cardiac troponin T (cTnT) promoter, were employed to downregulate Zfp36 expression in cardiac tissues (Figure S4I). This evidence concerns the gene ZFP36 and cardiac hypertrophy.
