铁凋亡是一种铁依赖性的非凋亡性细胞死亡,其特征是过度的脂质过氧化,并与肝脏中的过多病理条件相关。新出现的证据支持代谢途径失调和铁稳态受损通过铁凋亡在肝脏疾病进展中发挥作用的观点。虽然铁凋亡引起疾病的分子机制知之甚少,但几种铁凋亡相关基因和途径与肝脏疾病有关。在这里,我们回顾了肝脏在处理营养物质中的生理作用,我们目前对铁代谢的理解,铁凋亡的特点,以及调节铁凋亡的机制。此外,我们总结了铁凋亡在肝脏疾病的发病机制中的作用,包括肝损伤,非酒精性脂肪性肝炎,肝纤维化,肝硬化和肝细胞癌。最后,我们讨论了靶向铁凋亡管理肝脏疾病的治疗潜力。
Ferroptosis is an iron-dependent form of non-apoptotic cell death characterized by excessive lipid peroxidation and associated with a plethora of pathological conditions in the liver. Emerging evidence supports the notion that dysregulated metabolic pathways and impaired iron homeostasis play a role in the progression of liver disease via ferroptosis. Although the molecular mechanisms by which ferroptosis causes disease are poorly understood, several ferroptosis-associated genes and pathways have been implicated in liver disease. Here, we review the physiological role of the liver in processing nutrients, our current understanding of iron metabolism, the characteristics of ferroptosis, and the mechanisms that regulate ferroptosis. In addition, we summarize the role of ferroptosis in the pathogenesis of liver disease, including liver injury, non-alcoholic steatohepatitis, liver fibrosis, liver cirrhosis, and hepatocellular carcinoma. Finally, we discuss the therapeutic potential of targeting ferroptosis for managing liver disease.
