Ketogenic diet and β-hydroxybutyrate inhibit HDAC1 to preserve vascular smooth muscle cell function in thoracic aortic aneurysm

Our study reveals the important roles of KD and BHB in regulating HDAC1, preserving mitochondrial function, maintaining VSMC phenotype, and reducing oxidative stress in TAA. Our findings demonstrate KD and BHB as promising therapeutic strategies for treating TAA by targeting specific molecular pathways involved in its progression. This study highlights the significance and innovation of lifestyle interventions, such as KD, in mitigating TAA by addressing its underlying molecular mechanisms.
