  "abstract": "Background: Heart failure (HF) is increasingly recognized as a systemic disorder involving inter-organ communication. However, the role of the liver-heart axis in cardiac remodeling remains poorly understood. Selenoprotein P (Selenop), a hepatokine involved in systemic metabolic regulation, has been associated with HF, but its causal and tissue-specific contributions to cardiac remodeling remain unclear.\n\nMethods and results: We investigated the role of Selenop in pressure overload–induced cardiac remodeling using a transverse aortic constriction (TAC) in global and hepatocyte-specific Selenop knockout mice. TAC increased hepatic Selenop expression and circulating Selenop protein without altering cardiac Selenop expression. These changes were accompanied by reduced hepatic Akt and FoxO1 phosphorylation. Global Selenop deficiency improved survival and attenuated TAC-induced cardiac hypertrophy, pulmonary congestion, systolic dysfunction, and interstitial fibrosis. Transcriptomic and quantitative RT-PCR analyses showed that Selenop deficiency reduced cardiac Tgfb1 expression and attenuated TGF-β-associated profibrotic genes, including extracellular matrix-related genes. Hepatocyte-specific Selenop deletion markedly reduced circulating Selenop and attenuated TAC-induced cardiac hypertrophy, pulmonary congestion, systolic dysfunction, and profibrotic gene expression.\n\nConclusions: Hepatocyte-derived Selenop contributes to adverse cardiac remodeling under pressure overload and is associated with a TGF-β-related profibrotic transcriptional response in the heart. These findings support Selenop-mediated liver-heart communication as a potential mechanism of HF progression.",
