The aim of this study is to elucidate the mechanism of metadoxine through which it attenuates alcoholic liver disease-associated hepatic steatosis. In this study, the effect of metadoxine on alcoholic liver disease was evaluated in mouse model of alcoholic liver disease induced by high alcohol and high fat diets. In addition, RNA sequencing (RNA-Seq) of the liver tissues was applied to determine the dominant signaling pathways in response to metadoxine treatment. The mechanism of metadoxine on metabolic was investigated by mitochondrial function in HepG2 cells. The animal experiments in this study were conducted in accordance with the guidelines of the Ethics Committee for Scientific Research of Hefei University of Technology and were approved by the Animal Experiment Ethics Committee (approval No.: HUFT20210615002). When mice were fed a diet designed to induce alcoholic liver disease, hepatic lipid accumulation resulted. In this study, the level of serum biomarkers of liver injury, such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), was substantially decreased in mice treated with metadoxine compared to the model group (P < 0.05). Meanwhile, the inflammatory infiltration and steatosis in liver were alleviated by the administration of metadoxine compared to the model group (P < 0.01). In vitro, metadoxine significantly reversed ethanol overload-induced impairment of mitochondrial respiratory function and increased mitochondrial membrane potential in hepatocytes. Transcriptomic sequencing (RNA-Seq) analysis of liver tissue identified significant enrichment of the mitogen-activated protein kinase (MAPK) signaling pathway. Measurement of MAPK phosphorylation levels in liver tissue showed that metadoxine treatment significantly reduced MAPK phosphorylation (P < 0.01). Furthermore, the protective effects of metadoxine were abolished upon co-treatment with a p38-MAPK inhibitor. Conversely, co-treatment with a p38-MAPK activator reversed the inhibitory effect of metadoxine on p38-MAPK phosphorylation. This study investigated the mechanism of metadoxine in alcoholic liver disease and found that metadoxine enhanced mitochondrial function by the phosphorylation of MAPK and reduced the lipid accumulation and inflammation in alcoholic liver disease.

为探究美他多辛在酒精性肝病中抑制肝脏细胞脂肪变性的作用机制, 本研究采用美他多辛灌胃治疗高脂高乙醇饮食诱导的酒精性肝病小鼠, 通过肝脏组织的转录组测序(RNA sequencing, RNA-Seq) 分析药物作用的通路; 利用乙醇损伤诱导的HepG2细胞线粒体损伤模型探究美他多辛对线粒体功能的影响, 从而探究美他多辛改善脂代谢的作用机制。本研究动物实验遵循合肥工业大学科学研究伦理委员会的规定并通过动物实验伦理审查(批号: HUFT20210615002)。实验结果表明, 酒精性肝病饮食喂养的小鼠出现了肝脏脂质蓄积。体内实验发现, 美他多辛给药后的小鼠血脂水平与模型组相比下降(P < 0.05), 肝功能损伤减少(P < 0.05), 肝细胞炎性浸润和脂肪变性显著性减少(P < 0.01)。体外实验发现, 美他多辛显著逆转了乙醇处理引起的肝细胞线粒体呼吸功能损伤, 并增加了线粒体膜电位。通过肝脏组织的RNA-Seq分析发现丝裂原活化蛋白激酶(mitogen-activated protein kinase, MAPK) 通路明显富集。通过对肝组织的MAPK磷酸化水平的测定, 发现美他多辛处理可显著降低p38 MAPK的磷酸化水平(P < 0.01)。而p38-MAPK抑制剂和美他多辛共处理后, 美他多辛的作用抵消。而p38-MAPK激活剂和美他多辛共处理的情况下, 可逆转美他多辛对p38-MAPK磷酸化的抑制作用。美他多辛促进p38 MAPK磷酸化并增强线粒体呼吸功能, 减少肝细胞的脂质积累, 减少肝脏炎症, 从而改善酒精性肝病。

为探究美他多辛在酒精性肝病中抑制肝脏细胞脂肪变性的作用机制, 本研究采用美他多辛灌胃治疗高脂高乙醇饮食诱导的酒精性肝病小鼠, 通过肝脏组织的转录组测序(RNA sequencing, RNA-Seq) 分析药物作用的通路; 利用乙醇损伤诱导的HepG2细胞线粒体损伤模型探究美他多辛对线粒体功能的影响, 从而探究美他多辛改善脂代谢的作用机制。本研究动物实验遵循合肥工业大学科学研究伦理委员会的规定并通过动物实验伦理审查(批号: HUFT20210615002)。实验结果表明, 酒精性肝病饮食喂养的小鼠出现了肝脏脂质蓄积。体内实验发现, 美他多辛给药后的小鼠血脂水平与模型组相比下降(P < 0.05), 肝功能损伤减少(P < 0.05), 肝细胞炎性浸润和脂肪变性显著性减少(P < 0.01)。体外实验发现, 美他多辛显著逆转了乙醇处理引起的肝细胞线粒体呼吸功能损伤, 并增加了线粒体膜电位。通过肝脏组织的RNA-Seq分析发现丝裂原活化蛋白激酶(mitogen-activated protein kinase, MAPK) 通路明显富集。通过对肝组织的MAPK磷酸化水平的测定, 发现美他多辛处理可显著降低p38 MAPK的磷酸化水平(P < 0.01)。而p38-MAPK抑制剂和美他多辛共处理后, 美他多辛的作用抵消。而p38-MAPK激活剂和美他多辛共处理的情况下, 可逆转美他多辛对p38-MAPK磷酸化的抑制作用。美他多辛促进p38 MAPK磷酸化并增强线粒体呼吸功能, 减少肝细胞的脂质积累, 减少肝脏炎症, 从而改善酒精性肝病。

The aim of this study is to elucidate the mechanism of metadoxine through which it attenuates alcoholic liver disease-associated hepatic steatosis. In this study, the effect of metadoxine on alcoholic liver disease was evaluated in mouse model of alcoholic liver disease induced by high alcohol and high fat diets. In addition, RNA sequencing (RNA-Seq) of the liver tissues was applied to determine the dominant signaling pathways in response to metadoxine treatment. The mechanism of metadoxine on metabolic was investigated by mitochondrial function in HepG2 cells. The animal experiments in this study were conducted in accordance with the guidelines of the Ethics Committee for Scientific Research of Hefei University of Technology and were approved by the Animal Experiment Ethics Committee (approval No.: HUFT20210615002). When mice were fed a diet designed to induce alcoholic liver disease, hepatic lipid accumulation resulted. In this study, the level of serum biomarkers of liver injury, such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), was substantially decreased in mice treated with metadoxine compared to the model group (P < 0.05). Meanwhile, the inflammatory infiltration and steatosis in liver were alleviated by the administration of metadoxine compared to the model group (P < 0.01). In vitro, metadoxine significantly reversed ethanol overload-induced impairment of mitochondrial respiratory function and increased mitochondrial membrane potential in hepatocytes. Transcriptomic sequencing (RNA-Seq) analysis of liver tissue identified significant enrichment of the mitogen-activated protein kinase (MAPK) signaling pathway. Measurement of MAPK phosphorylation levels in liver tissue showed that metadoxine treatment significantly reduced MAPK phosphorylation (P < 0.01). Furthermore, the protective effects of metadoxine were abolished upon co-treatment with a p38-MAPK inhibitor. Conversely, co-treatment with a p38-MAPK activator reversed the inhibitory effect of metadoxine on p38-MAPK phosphorylation. This study investigated the mechanism of metadoxine in alcoholic liver disease and found that metadoxine enhanced mitochondrial function by the phosphorylation of MAPK and reduced the lipid accumulation and inflammation in alcoholic liver disease.

酒精性肝病(alcoholic liver disease, ALD) 是全球范围内导致肝硬化和肝相关死亡的主要原因之一[1]。因持续酒精摄入导致肝癌的发生甚至死亡的比例已增加至饮酒者30%~40%。酒精性肝病病因复杂, 基因遗传、酒精摄入和排出失衡、炎症和氧化应激以及衰老等均是引起酒精性肝病迅速进展的重要原因, 其病理进程复杂, 通常始于单纯性肝脂肪变性, 并可进一步发展为酒精性脂肪性肝炎、肝纤维化, 最终导致肝硬化甚至肝细胞癌[2, 3]。酒精持续摄入引起的内质网应激和线粒体功能紊乱是导致肝细胞损伤的直接原因, 最终导致肝硬化[4]。线粒体是脂质代谢的重要场所, 线粒体在ATP生成、代谢物分解、细胞命运等方面起着关键作用, 线粒体功能的改变被认为是酒精性肝病进展过程中的关键事件[5]。因此, 线粒体功能异常和脂肪变性是酒精性肝病进展的重要病理基础。
酒精性肝病发病机制复杂, 而目前酒精性肝病的治疗手段有限[6]。临床研究发现, 高脂Lieber-DeCarli液体饲料维持酒精摄入的模型中, 高脂饮食与酒精滥用之间的协同效应显著加剧了肝脏的脂质堆积与氧化应激, 从而共同促进肝损伤的严重程度与进展。美他多辛作为一种自2017年上市的护肝药, 广泛应用于酒精性肝病患者及酒精中毒患者的症状缓解。美他多辛是一种抗氧化剂, 能够增强乙醛脱氢酶活性, 降低血清中乙醇浓度[7]。此外, 美他多辛通过减少肝星状细胞活化减缓肝脏纤维化进程[8]。而与此同时, 在酒精性肝病的发病机制中, 线粒体损伤是导致肝脏脂肪变性的重要原因, 关于美他多辛如何通过影响线粒体功能改善肝脂肪变性的作用机制仍不清晰[9]。美他多辛在酒精性肝病中抑制肝脏细胞脂肪变性的作用机制仍待进一步研究。
小鼠在高酒精饮食造模的状态下, 其肝脏损伤持续增加, 并伴有炎症的发生[10], 与高酒精饮食人群的肝脏特征相吻合, 故常用于模拟人类酒精性肝病的模型[11]。本研究在确认美他多辛的药效基础之上, 进一步采用转录组测序(RNA sequencing, RNA-Seq) 技术深入探索其作用机制。通过对转录组数据的分析, 本研究焦点集中于美他多辛对肝脏脂质代谢, 尤其是线粒体相关基因表达的调控。此外, 本研究通过细胞实验直接评估了美他多辛对线粒体功能的关键指标, 旨在阐明其通过改善线粒体功能以减轻肝脏脂质堆积的分子机制, 为揭示酒精性肝病的致病机制及开发新型治疗药物提供了新的实验依据和思路。

数据分析及处理  本文中所有数据用平均值±标准误(mean ± SEM) 表示, 使用SPSS 20.0软件进行组间的单因素方差分析, 采用最小差异数法检验进行多重比较。P < 0.05代表差异有统计学意义, 通过Prism GraphPad 10.1.2作图展示数据。
小鼠酒精性肝病模型的构建流程如图1A所示。与模型组比较, 美他多辛干预显著缓解了因造模引起的小鼠体重下降(图1B)。同时, 美他多辛治疗后, 小鼠肝脏形态趋于正常, 肝脏重量也有所恢复(图1C、D)。AST、ALT和ALP是肝脏中关键的代谢酶, 当肝细胞受损时, 这些酶被大量释放入血, 因此其活性水平是评价肝脏炎症和损伤程度的重要指标。与对照组相比, 模型组小鼠血清中ALT、AST和ALP水平均显著升高; 而与模型组相比, 美他多辛给药组ALT水平未明显降低, 而AST和ALP的水平均显著降低, 表明美他多辛有助于促进酒精性肝病小鼠肝功能的恢复(图1E、F、I)。通过肝脏组织HE染色进行病理学分析发现, 与模型组相比, 美他多辛治疗组中央静脉周围肝索结构更为清晰, 肝细胞排列更加整齐, 肝细胞气球样变和炎症浸润明显减轻。根据气球样变和脂肪变性评分标准对HE染色结果进行统计, 结果显示美他多辛治疗后小鼠肝脏气球样变水平显著降低(图1G、H)。在酒精性肝病中, TNF-α和IL-6的表达水平通常升高。在本研究中, 与模型组相比, 美他多辛干预组小鼠的TNF-α和IL-6水平均显著下降(图1J、K)。这表明美他多辛能显著减轻乙醇诱导的肝脏炎症反应。通过生化分析仪检测小鼠血脂水平发现, 与模型组相比, 美他多辛治疗后血清中TC、TG和LDL-C水平均显著降低, 降幅分别为10.14%、25.09%和29.23%, 而HDL-C水平则显著升高, 升幅为29.55% (图1L~O)。以上结果提示, 美他多辛能够改善肝脏脂质代谢水平。
RNA-Seq主成分分析结果显示, 美他多辛给药组与模型组以及对照组的小鼠的肝脏样本在基因表达上呈现明显分离, 表明美他多辛对小鼠整体基因表达产生了显著影响(图2A)。与对照组相比, 模型组共有5 061个基因上调和2 423个基因下调, 而美他多辛给药组共有5 361个基因上调和1 965个基因下调。与模型组相比, 美他多辛给药组共有649个基因上调和402个基因下调(图2B)。基于此, 通过火山图进行展示美他多辛给药组和模型组的差异表达基因, 如图所示, 其中红色为上调基因, 而蓝色为下调基因, 值得注意的是胆固醇合成的相关基因如Srebf1显著性下调(图2C)。通过对这些差异基因进行GO细胞组分富集分析, 发现它们显著富集于细胞膜(13.22%) 和细胞质(12.59%) 等结构(图2D)。该结果提示美他多辛的作用可能广泛影响了包括膜受体信号转导、胞内代谢反应及物质运输在内的多个关键生物学过程。为进一步探究其生物学功能, 本研究通过Reactome通路数据库差异基因进行了富集分析。结果显示, 生物氧化、脂肪酸代谢以及脂质代谢等相关通路中的基因也显著富集。值得注意的是, 目前富集到的基因数量前三的通路均与代谢过程相关, 这一发现从分子层面解释了美他多辛参与代谢过程的作用机制(图2E)。为深入探究美他多辛改善酒精性肝病的分子机制, 本研究进一步检测了肝脏组织中酒精肝相关基因Aldh1b1、Cyp2e1、Srebf1和Nfkb1等的表达水平。与模型组相比, 美他多辛干预显著改变了多个调控因子的mRNA表达水平: 一方面, 美他多辛上调了乙醛代谢关键酶Aldh1b1的表达(图2F); 另一方面, 美他多辛显著下调了与氧化应激作用相关的基因Cyp2e1 mRNA表达水平(图2G)、脂质合成关键转录因子Srebf1 (图2H) 和炎症核心调控因子Nfκb1 (图2I) 的mRNA水平。上述结果共同表明, 美他多辛通过促进乙醛清除、减轻氧化应激、抑制脂质生成及缓解炎症反应等多重途径, 协同发挥其对酒精性脂肪肝的改善作用。
深入分析转录组数据发现, 美他多辛给药后能显著上调乙醛脱氢酶(Aldh1b1) 的表达, 并引起多个糖脂代谢关键基因(如Fabp1、Hsd3b5、Srebf1、Acly等) 的广泛变化, 且在美他多辛给药后, 这些基因的表达接近对照组(图3A)。鉴于线粒体在脂质氧化磷酸化中的核心地位, 本研究在乙醇诱导的细胞损伤模型中对线粒体功能进行了评估。结果显示, 美他多辛处理能全面增强线粒体功能(图3B)。具体而言, 美他多辛显著提升了细胞的基础呼吸能力(图3C) 与线粒体呼吸潜力(图3E), 并促进了ATP的生成(图3D), 同时降低了非线粒体途径的氧消耗(图3F), 增加线粒体质子漏(图3G), 这表明其作用主要依赖于线粒体氧耗途径。此外, 本研究分别进行了线粒体形态与功能分析。Mito-tracker deep red染色显示, 乙醇处理导致肝细胞线粒体网络发生显著碎片化, 正常的管状结构被大量分散的点所取代, 而美他多辛处理后, 线粒体网状形态得到明显改善与恢复(图3H)。同时, JC-1染色结果表明, 模型组细胞的线粒体膜电位(ΔΨm) 显著降低, 表现为红/绿荧光强度比的急剧下降(图3I)。这表明乙醇暴露破坏了线粒体的结构完整性, 严重损害了线粒体呼吸功能。而美他多辛能增强线粒体呼吸功能(如能增加线粒体基础呼吸能力和ATP生成能力), 这种作用可能是美他多辛减轻肝脏脂质堆积的原因之一。
为深入探究美他多辛对线粒体功能的作用机制, 本研究对转录组测序数据进行了通路富集分析。结果显示, 美他多辛处理后, 脂质代谢过程和脂肪酸代谢相关通路发生显著变化(图4A)。KEGG分析进一步表明, 美他多辛给药组的MAPK信号通路显著富集(图4B)。基于此, 本研究对肝组织中MAPK信号通路的亚型如p38和JNK进行了验证。如图4C所示, 相较于对照组, 模型组的p38 MAPK的磷酸化水平显著上升, MAPK信号通路中的JNK磷酸化水平未见明显改变。与此同时, 美他多辛给药后, p38 MAPK磷酸化水平相较于模型组显著性下调, 而MAPK信号通路中的JNK磷酸化水平未见明显改变, 提示美他多辛对MAPK通路的激活可能主要集中于p38 MAPK (图4C、D)。本研究进一步在细胞水平通过Western blot对p38 MAPK和JNK进行了检测。与组织结果一致, 在模型组中p38 MAPK磷酸化水平显著升高, 而美他多辛给药后其磷酸化明显降低; JNK则未呈现显著变化(图4E、F)。以上结果表明, 美他多辛的作用机制可能与p38 MAPK通路密切相关。
为探究美他多辛是否通过p38 MAPK通路发挥作用, 本研究使用p38 MAPK特异性抑制剂skepinone-L进行处理。如图5A~C所示, skepinone-L处理有效抑制p38 MAPK的磷酸化。值得注意的是, 在skepinone-L存在下, 美他多辛的加入并未进一步降低p-p38 MAPK水平, 其与单独skepinone-L处理组相比无显著差异, 提示美他多辛的作用主要依赖于p38 MAPK磷酸化。此外, 本研究在造模条件下检测了细胞中TC和TG含量。在skepinone-L存在的情况下, 美他多辛并未引起TC与TG水平的进一步下降, 其与单独skepinone-L处理组相比亦无显著差异(图5D、E)。此外, 在小鼠肝细胞AML12细胞系模型中也重复了同样处理。如图5F所示, 在skepinone-L处理下, p38 MAPK磷酸化被抑制, 此时美他多辛未表现出额外的抑制作用。相应的TC与TG检测结果(图5I、J), 在skepinone-L存在的情况下, 美他多辛未进一步降低脂质聚集。表明美他多辛主要通过p38 MAPK通路发挥调控作用。为了进一步说明美他多辛通过p38磷酸化增强线粒体功能, 本研究利用Seahorse技术检测线粒体呼吸功能(5K), 结果显示, skepinone-L处理能全面增强线粒体功能(图5L)。具体而言, skepinone-L显著提升了细胞的基础呼吸能力(图5M) 并促进了ATP的生成(图5N) 与线粒体呼吸潜力(图5O), 同时增加了非线粒体途径的氧消耗(图5P), 并少量增加质子漏水平(图5Q)。而在skepinone-L处理的情况下, 美他多辛与单独的skepinone-L处理组无显著性差异。这表明美他多辛改善线粒体功能的作用主要依赖于其对p38磷酸化的抑制。
为了进一步验证美他多辛通过p38 MAPK磷酸化发挥作用, 本研究设计了反向验证实验, 采用特异性p38激活剂分别在HepG2人肝癌细胞及AML12小鼠正常肝细胞中进行干预。在HepG2细胞中, p38 MAPK激活剂处理显著上调了p38磷酸化水平, 而美他多辛处理能够有效逆转该效应(图6A~C), 提示美他多辛可抑制p38通路的激活。此外, 在AML12细胞中的结果与HepG2模型一致: 美他多辛同样能显著抑制激活剂诱导的p38磷酸化水平升高(图6D~F)。以上结果在多种细胞模型中共同证实, 美他多辛能够直接干预p38 MAPK的磷酸化过程, 从反向角度进一步明确了美他多辛通过抑制p38 MAPK激活发挥功能的作用机制。
酒精性肝病是一种持续酒精性饮食引起的肝脏病理性变化, 大约20%~40%的酗酒者会发展为更严重的酒精性肝病阶段, 包括酒精性肝炎、肝硬化, 甚至肝衰竭[14], 酒精性肝病的药物开发仍备受研究者的关注[15, 16]。乙醇饮食能够引起肝细胞损伤, 线粒体功能障碍[17, 18], 进而引起细胞内炎症因子的激活, 从而活化肝星状细胞并促进肝纤维化进程[19, 20]。本研究表明, 在酒精性肝病模型中, 美他多辛能有效缓解酒精饮食引发的肝脏脂肪变性与炎症损伤。美他多辛给药后改善了小鼠体重以及血脂水平异常, 并改善了小鼠的肝功能。深入分析发现, 疗效的核心环节在于美他多辛抑制了肝脏的炎症反应, 从而减少肝星状细胞激活和抑制肝纤维化进程。
美他多辛的肝保护作用可能源于其对肝细胞核心代谢单元的多靶点调控[21]。经典的“解酒”与“抗氧化”机制为促进乙醛代谢与提升谷胱甘肽水平, 是其改善酒精性肝损伤的重要途径[22, 23]。本研究发现, 美他多辛能逆转乙醇诱导的线粒体功能障碍, 这一发现为理解美他多辛的护肝作用提供了全新视角。本研究认为, 美他多辛的核心作用源于其对肝细胞线粒体功能的改善作用。线粒体损伤是酒精性与代谢性肝病共同的终末通路, 美他多辛通过强化这一细胞“能量工厂”的功能, 从上游同时缓解氧化应激、脂质堆积及炎症反应, 在多种肝损伤模型中发挥治疗效应。这一机制与美他多辛传统的抗氧化剂的定位不同, 将美他多辛提升为一种能够“改善细胞代谢基础”的多功能的肝保护剂, 这也为其显著的临床有效性与良好耐受性提供了新的理论解释。正是基于这一机制, 美他多辛展现出相较于水飞蓟宾、维生素E等传统直接抗氧化剂的显著优势: 它不仅通过提升谷胱甘肽水平增强“下游”抗氧化防御机制, 更能通过加速清除关键毒性代谢物乙醛从“上游”进行病因干预, 同时兼具改善线粒体功能, 实现了从病因清除到功能修复的多靶点协同治疗。
本研究利用RNA-Seq技术, 表明美他多辛通过激活MAPK信号通路, 成为改善肝细胞线粒体代谢、缓解肝脏炎症与纤维化的关键驱动因素。从而将美他多辛的作用与调控氧化应激与代谢的核心信号通路联系了起来。值得注意的是, MAPK通路在肝脏疾病中扮演着复杂的角色, 其特定分支(如p38或JNK) 的激活通常与生存信号和代谢调节相关。因此, 美他多辛所触发的很可能是一种保护性的MAPK信号, 从而协同促进能量代谢、抑制氧化应激与炎性细胞因子的产生, 并阻断肝星状细胞的活化, 为其“广谱”且根本性的护肝作用提供了强有力的机制证据[24, 25]。
本研究通过转录组测序与细胞生物学实验相结合, 系统揭示了美他多辛在酒精性肝病中的作用机制。研究发现, 美他多辛的肝保护效应核心在于对p38 MAPK信号通路的特异性激活。这一激活事件起到了中枢调控作用, 其下游通过直接促进肝细胞线粒体功能与增强脂质代谢, 从根源上减少了肝脏脂质堆积; 同时, p38 MAPK通路可能进一步通过调控其经典下游靶点, 如核因子-κB (NF-κB), 来抑制关键炎症因子及肝纤维化标志物的表达, 从而协同缓解肝脏的炎症与损伤[26, 27]。值得注意的是, 肝病中的氧化应激是另一核心病理环节, 尽管有研究报道Nrf2通路是调控氧化应激的关键靶点[28, 29], 但本研究的初步数据提示, 美他多辛的抗氧化作用可能独立于经典的Nrf2通路, 或与其他信号网络存在交叉对话, 这揭示了美他多辛作用机制的独特性与复杂性。
前期研究发现活化的p38 MAPK (p-p38) 可抑制线粒体功能, 通过磷酸化呼吸链复合物I和IV的亚基, 抑制线粒体酶活性, 降低氧化磷酸化效率和减少ATP合成[30]。本研究在酒精应激下, p-p38水平升高且线粒体呼吸功能(基础呼吸、ATP生成呼吸) 被抑制。细胞模型的研究发现, 使用skepinone-L抑制p38 MAPK与美他多辛对线粒体呼吸功能的改善作用相似, 且在skepinone-L存在时美他多辛无额外的效果叠加。这表明, 在酒精肝损伤时, p38 MAPK的异常激活是线粒体功能障碍的原因之一。此外, 研究表明, 线粒体功能障碍产生的活性氧是激活p38 MAPK上游激酶(如ASK1) 的关键信号[31]。活化的p-p38又可进一步损害线粒体, 导致线粒体碎片化, 功能不全的碎片化线粒体更易产生活性氧自由基[32]。本研究观察到酒精处理导致线粒体网状结构破坏, 而美他多辛可部分恢复线粒体形态, 这提示美他多辛可能抑制p-p38, 间接恢复线粒体功能。美他多辛的疗效主要通过抑制p38 MAPK磷酸化来实现。此外, p38 MAPK通过抑制线粒体功能, 可能间接导致脂肪酸氧化受阻, 转而促进脂质重新酯化为甘油三酯, 并在肝细胞内蓄积[33]。在本研究中, 抑制p38 MAPK可显著降低肝细胞内的TC和TG水平。这提示美他多辛通过抑制p38 MAPK磷酸化改善酒精性肝病肝细胞脂肪变性的机制。
综上所述, 本研究发现美他多辛可通过p38 MAPK信号通路, 显著减轻酒精性肝病小鼠的肝脂肪变性与炎症水平, 从而发挥明确的肝脏保护作用。进一步机制研究表明, 美他多辛能够有效增强肝细胞线粒体呼吸功能, 改善能量代谢状态, 提示其护肝作用与线粒体功能调控密切相关。上述结果从p38 MAPK通路角度阐释了美他多辛降低肝脏脂质积累的新机制, 拓展了对其多靶点护肝作用机制的理解, 为酒精性肝病的药物研发提供了新的实验依据和理论支撑。
