Abstract

Ascending incidence and poor outcomes make Alcoholic Liver Disease (ALD) a considerable public health concern. This review concluded the iron metabolism under physiology conditions and alcohol disturbance (leading to ferroptosis in ALD) and summarized the novel treatment, diagnosis, and prognosis of ferroptosis for ALD. ALD is characterized by alcohol-induced chronic metabolism disorder, peroxidation damage, and dysfunction of the anti-oxidant system. Current animal experiments and clinical studies identified ferroptosis as a new form of regulated cell death involved in ALD. One strong evidence is that the key iron regulatory hormone, hepcidin, is downgraded in ALD through NF-κB/IL-6/STAT3, BMP/SMAD, and Jak/STAT3 pathways, which would impair iron hemostasis and induce ferroptosis in ALD. Also, imbalance metabolism and other pathological responses in ALD induce and regulate ferroptosis, which proves ferroptosis participates in the pathophysiology of ALD via oxidative stress, steatosis, and fibrosis. Inhibition of ferroptosis via regulating hepcidin expression and metabolism impairment may provide new therapies for ALD.

铁蛋白沉积在 ALD 中的作用:关注肝素和肝素以外的其他蛋白。
酒精性肝病(ALD)的发病率不断上升,且治疗效果不佳,是一个相当令人担忧的公共卫生问题。本综述总结了生理条件下的铁代谢和酒精干扰(导致 ALD 中的铁变态反应),并总结了 ALD 中铁变态反应的新型治疗、诊断和预后。ALD 的特点是酒精引起的慢性代谢紊乱、过氧化损伤和抗氧化系统功能失调。目前的动物实验和临床研究发现,铁蜕变是参与 ALD 的一种新的调节性细胞死亡形式。一个有力的证据是,在 ALD 中,关键的铁调节激素血钙素通过 NF-κB/IL-6/STAT3、BMP/SMAD 和 Jak/STAT3 通路被降级,这将损害铁的止血作用并诱导 ALD 中的铁细胞凋亡。此外,新陈代谢失衡和 ALD 的其他病理反应也会诱导和调节铁变态反应,这证明铁变态反应通过氧化应激、脂肪变性和纤维化参与了 ALD 的病理生理学。通过调节血红素的表达和代谢障碍来抑制铁蛋白沉积,可能会为 ALD 提供新的疗法。
