Curcumol ameliorates alcohol and high-fat diet-induced fatty liver disease via modulation of the Ceruloplasmin/iron overload/mtDNA signaling pathway. J Nutr Biochem 2025; 136:109807. [PMID: 39549858 DOI: 10.1016/j.jnutbio.2024.109807] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2024] [Revised: 09/28/2024] [Accepted: 11/11/2024] [Indexed: 11/18/2024]
Abstract
Fatty liver disease (FLD), a chronic liver disease characterized by excessive lipid deposition, is affecting more and more people worldwide owing to the increasing global incidence of obesity and heavy alcohol consumption. However, there is still no effective strategy for prevention or treatment of alcohol and high-fat diet (HFD)-induced FLD. The purpose of this study was to investigate the effect of curcumol on alcohol and HFD-induced FLD and the underlying molecular mechanisms. The results showed that curcumol ameliorated alcohol and HFD-induced hepatocyte injury in vivo and in vitro, and the mechanism might be related to its up-regulation of ceruloplasmin and subsequent alleviation of iron overload. Moreover, curcumol inhibited alcohol and HFD-induced mitochondrial damage and mtDNA release in hepatocytes by modulating iron overload. Furthermore, curcumol's inhibition of mtDNA release could suppress the activation of cGAS-STING and subsequent inflammation, and this phenomenon could be reversed by cGAS overexpression. Notably, alcohol and HFD-induced mtDNA release from hepatocytes contributed to HSC activation and this effect could be weakened by curcumol. In conclusion, these findings elucidated that curcumol ameliorated alcohol and HFD-induced FLD via modulating ceruloplasmin/iron overload/mtDNA signaling pathway, which lead to the inhibition of inflammation and HSCs activation.

Abstract
Ceruloplasmin (CP) is a multicopper oxidase and antioxidant that is mainly produced in the liver. CP not only plays a crucial role in the metabolic balance of copper and iron through its oxidase function but also exhibits antioxidant activity. In addition, CP is an acute-phase protein. In addition to being associated with aceruloplasminemia and neurodegenerative diseases such as Wilson's disease, Alzheimer's disease, and Parkinson's disease, CP also plays an important role in metabolic diseases, which are caused by metabolic disorders and vigorous metabolism, mainly including diabetes, obesity, hyperlipidemia, etc. Based on the physiological functions of CP, we provide an overview of the association of type 2 diabetes, obesity, hyperlipidemia, coronary heart disease, CP oxidative stress, inflammation, and metabolism of copper and iron. Studies have shown that metabolic diseases are closely related to systemic inflammation, oxidative stress, and disorders of copper and iron metabolism. Therefore, we conclude that CP, which can reduce the formation of free radicals in tissues, can be induced during inflammation and infection, and can correct the metabolic disorder of copper and iron, has protective and diagnostic effects on metabolic diseases.
