Abstract

Background: With the improvement in living standards, metabolic dysfunction-associated steatotic liver disease (MASLD) has become the most common chronic liver disease worldwide, garnering increasing concern due to its significant health risks. MASLD encompasses a spectrum of pathological processes ranging from simple steatosis to non-alcoholic steatohepatitis (NASH), liver fibrosis, cirrhosis, and even hepatocellular carcinoma (HCC), and it has become a leading cause of liver-related mortality. Due to the lack of specific therapeutic targets, current diagnostic, treatment, and management strategies for MASLD remain inadequate.

Summary: This review aims to explore the pathophysiological manifestations of MASLD, the mechanisms through which HIF-1α contributes to disease progression, and the potential therapeutic approaches targeting HIF-1α, offering feasible strategies for treating advanced MASLD.

Key message: Studies suggest that hepatocytes in MASLD are often in a hypoxic state, which activates hypoxia-inducible factor-1α (HIF-1α), playing a crucial role in disease progression. During hypoxia, the expression of HIF-1α increases throughout the different stages of MASLD, interacting with various genes and pathways, influencing lipid metabolism, steatosis, and fibrosis progression.

HIF-1α调节代谢功能障碍相关脂肪变性肝病的进展。
背景:随着生活水平的提高,代谢功能障碍相关脂肪变性肝病(MASLD)已成为世界范围内最常见的慢性肝病,因其严重的健康风险而日益受到关注。MASLD包括一系列病理过程,从单纯脂肪变性到非酒精性脂肪性肝炎(NASH)、肝纤维化、肝硬化,甚至肝细胞癌(HCC),它已成为肝脏相关死亡的主要原因。由于缺乏具体的治疗靶点,目前对MASLD的诊断、治疗和管理策略仍然不足。摘要:本文旨在探讨MASLD的病理生理表现、HIF-1α促进疾病进展的机制,以及针对HIF-1α的潜在治疗途径,为晚期MASLD的治疗提供可行的策略。关键信息:研究表明,MASLD的肝细胞常处于缺氧状态,激活缺氧诱导因子-1α (HIF-1α),在疾病进展中起关键作用。在缺氧期间,HIF-1α的表达在MASLD的不同阶段都有所增加,并与各种基因和途径相互作用,影响脂质代谢、脂肪变性和纤维化进展。

期刊介绍: ''Digestion'' concentrates on clinical research reports: in addition to editorials and reviews, the journal features sections on Stomach/Esophagus, Bowel, Neuro-Gastroenterology, Liver/Bile, Pancreas, Metabolism/Nutrition and Gastrointestinal Oncology. Papers cover physiology in humans, metabolic studies and clinical work on the etiology, diagnosis, and therapy of human diseases. It is thus especially cut out for gastroenterologists employed in hospitals and outpatient units. Moreover, the journal''s coverage of studies on the metabolism and effects of therapeutic drugs carries considerable value for clinicians and investigators beyond the immediate field of gastroenterology.
