Liver fibrosis represents a reversible pathophysiological process, caused by chronic inflammation stemming from hepatocyte damage. It delineates the initial stage in the progression of chronic liver disease. This pathological progression is characterized by the excessive accumulation of the extracellular matrix (ECM), which leads to significant structural disruption and ultimately impairs liver function. To date, no specific antifibrotic drugs have been developed, and advanced liver fibrosis remains largely incurable. Liver transplantation remains the sole efficacious intervention for advanced liver fibrosis; nevertheless, it is constrained by exorbitant costs and the risk of postoperative immune rejection, underscoring the imperative for novel therapeutic strategies. Ferroptosis, an emergent form of regulated cell death, has been identified as a pivotal regulatory mechanism in the development of liver fibrosis and is intricately linked with the progression of liver diseases. Recent investigations have elucidated that a diverse array of non-coding RNAs (ncRNAs), including microRNAs, long non-coding RNAs, and circular RNAs, are involved in the ferroptosis pathway, thereby modulating the progression of various diseases, including liver fibrosis. In recent years, the roles of ferroptosis and ferroptosis-related ncRNAs in liver fibrosis have attracted escalating scholarly attention. This paper elucidates the pathophysiology of liver fibrosis, explores the mechanisms underlying ferroptosis, and delineates the involvement of ncRNA-mediated ferroptosis pathways in the pathology of liver fibrosis. It aims to propose novel strategies for the prevention and therapeutic intervention of liver fibrosis.
肝纤维化是一种可逆的病理生理过程,由肝细胞损伤引发的慢性炎症所致。它是慢性肝病进展的初始阶段。这一病理进展的特征是细胞外基质(ECM)过度积累,导致严重的结构破坏并最终损害肝功能。迄今为止,尚未开发出特异性抗纤维化药物,晚期肝纤维化在很大程度上仍无法治愈。肝移植仍然是晚期肝纤维化唯一有效的干预措施;然而,它受到高昂成本和术后免疫排斥风险的限制,凸显了新型治疗策略的必要性。铁死亡是一种新出现的程序性细胞死亡形式,已被确定为肝纤维化发展中的关键调节机制,并且与肝脏疾病的进展密切相关。最近的研究表明,多种非编码RNA(ncRNA),包括微小RNA、长链非编码RNA和环状RNA,参与铁死亡途径,从而调节包括肝纤维化在内的各种疾病的进展。近年来,铁死亡及铁死亡相关ncRNA在肝纤维化中的作用已引起越来越多的学术关注。本文阐述了肝纤维化的病理生理学,探讨了铁死亡的潜在机制,并描述了ncRNA介导的铁死亡途径在肝纤维化病理中的作用。其目的是提出预防和治疗肝纤维化的新策略。
