Non‑alcoholic fatty liver disease (NAFLD) is a clinically progressive illness that can advance from simple fatty liver to non-alcoholic hepatitis and liver fibrosis. Cirrhosis and hepatocellular carcinoma are two of the most common diseases caused by NAFLD. As there are no early disease biomarkers and no US Food and Drug Administration‑approved medications, treatment for NAFLD is still focused on altering lifestyle and dietary habits, which makes it difficult to treat effectively. As a result, a novel treatment is urgently needed to prevent NAFLD progression. Calcium (Ca) channels regulate intracellular Ca homeostasis via the mediation of Ca flow. Previous studies have reported that Ca channel expression varies throughout the development and progression of NAFLD, which results in the dysregulation of intracellular Ca homeostasis, endoplasmic reticulum stress, mitochondrial dysfunction and autophagy suppression, all of which contribute to NAFLD progression. Several types of Ca channels (including two‑pore segment channel 2, transient receptor potential, inositol triphosphate receptor, voltage‑dependent anion channel 1, store‑operated Ca entry, purinergic receptor X7 and potassium Ca‑activated channel subfamily N member 4) have been identified as potential targets for preventing NAFLD development and controlling intracellular Ca homeostasis. To achieve this, these channels can be blocked or activated, which exerts anti‑steatotic, anti‑inflammatory, anti‑fibrotic and other effects, which ultimately prevents the development of NAFLD. In the present review NAFLD therapeutics and the treatments that target Ca channels that are currently being developed were examined.
非酒精性脂肪性肝病(NAFLD)是一种临床进展性疾病,可从轻度单纯性脂肪肝进展为非酒精性肝炎和肝纤维化。肝硬化和肝细胞癌是由 NAFLD 引起的最常见的两种疾病。由于没有早期疾病生物标志物和美国食品和药物管理局批准的药物,NAFLD 的治疗仍侧重于改变生活方式和饮食习惯,这使得难以有效治疗。因此,迫切需要一种新的治疗方法来预防 NAFLD 的进展。钙(Ca)通道通过 Ca 流的介导来调节细胞内 Ca 稳态。先前的研究报告称,NAFLD 的发生和发展过程中 Ca 通道的表达发生变化,导致细胞内 Ca 稳态失调、内质网应激、线粒体功能障碍和自噬抑制,所有这些都导致 NAFLD 的进展。几种类型的 Ca 通道(包括双孔段通道 2、瞬时受体电位、肌醇三磷酸受体、电压依赖性阴离子通道 1、储存操作 Ca 进入、嘌呤能受体 X7 和钾钙激活通道亚家族 N 成员 4)已被确定为预防 NAFLD 发展和控制细胞内 Ca 稳态的潜在靶点。为此,可以阻断或激活这些通道,发挥抗脂肪变性、抗炎、抗纤维化等作用,最终防止 NAFLD 的发展。本综述检查了目前正在开发的针对 Ca 通道的 NAFLD 治疗药物和治疗方法。
