As a result of a sedentary lifestyle and excess food consumption in modern society, non-alcoholic fatty liver disease (NAFLD) characterized by fat accumulation in the liver is becoming a major disease burden. Non-alcoholic steatohepatitis (NASH) is an advanced form of NAFLD characterized by inflammation and fibrosis that can lead to hepatocellular carcinoma and liver failure. Nuclear receptors (NRs) are a family of ligand-regulated transcription factors that closely control multiple aspects of metabolism. Their transcriptional activity is modulated by various ligands, including hormones and lipids. NRs serve as potential pharmacological targets for NAFLD/NASH and other metabolic diseases.
In this review, we provide a comprehensive overview of NRs that have been studied in the context of NAFLD/NASH with a focus on their transcriptional regulation, function in preclinical models, and studies of their clinical utility.
The transcriptional regulation of NRs is context-dependent. During the dynamic progression of NAFLD/NASH, NRs play diverse roles in multiple organs and different cell types in the liver, which highlights the necessity of targeting NRs in a stage-specific and cell-type-specific manner to enhance the efficacy and safety of treatment methods.
由于现代社会生活方式久坐不动和食物摄入过量,以肝脏脂肪堆积为特征的非酒精性脂肪性肝病(NAFLD)正成为主要疾病负担。非酒精性脂肪性肝炎(NASH)是一种进展性 NAFLD 形式,其特征为炎症和纤维化,可导致肝细胞癌和肝功能衰竭。核受体(NRs)是一类配体调控的转录因子家族,它们密切控制着代谢的多个方面。它们的转录活性受到各种配体的调节,包括激素和脂质。NRs 是治疗 NAFLD/NASH 和其他代谢性疾病的潜在药物靶点。
在这篇综述中,我们全面概述了在 NAFLD/NASH 背景下研究的 NRs,重点介绍了它们的转录调控、在临床前模型中的功能以及对其临床应用的研究。
NRs 的转录调控是上下文相关的。在 NAFLD/NASH 的动态进展过程中,NRs 在肝脏的多个器官和不同细胞类型中发挥着不同的作用,这突出了以阶段特异性和细胞类型特异性方式靶向 NRs 以提高治疗方法的疗效和安全性的必要性。
