Mitochondrion is an important metabolic and energetic organelle that regulates several cellular processes. Mitochondrial dysfunction has been related to liver diseases including hepatocellular carcinoma. As a result, the energetic demand is not properly supplied and mitochondrial morphologic changes have been observed, resulting in an altered metabolism. We previously demonstrated the chemopreventive effect of the hepatoprotector IFC-305. In this work we aimed to evaluate the functional, metabolic, and dynamic mitochondrial alterations in the sequential model of cirrhosis-hepatocellular carcinoma induced by diethylnitrosamine in rats and the possible beneficial effect of IFC-305. Experimental groups of rats were formed to induce cirrhosis-hepatocellular carcinoma and to assess the IFC-305 effect during cancer development and progression through the evaluation of functional, metabolic, and dynamic mitochondrial parameters. In this experimental model, dysfunctional mitochondria were observed and suspension of the diethylnitrosamine treatment was not enough to restore them. Administration of IFC-305 maintained and restored the mitochondrial function and regulated parameters implicated in metabolism as well as the mitochondrial dynamics modified by diethylnitrosamine intoxication. This study supports IFC-305 as a potential hepatocellular carcinoma treatment or as an adjuvant in chemotherapy.
线粒体是一种重要的代谢和能量细胞器,可调节多种细胞过程。线粒体功能障碍与包括肝细胞癌在内的肝脏疾病有关。因此,能量需求无法得到适当供应,并且观察到线粒体形态发生变化,导致代谢改变。我们之前证明了肝保护剂IFC - 305的化学预防作用。在这项工作中,我们旨在评估二乙基亚硝胺诱导的大鼠肝硬化 - 肝细胞癌序贯模型中的功能性、代谢性和动态线粒体改变,以及IFC - 305可能的有益作用。将大鼠分为实验组以诱导肝硬化 - 肝细胞癌,并通过评估功能性、代谢性和动态线粒体参数来评估IFC - 305在癌症发生和发展过程中的作用。在这个实验模型中,观察到线粒体功能障碍,并且停止二乙基亚硝胺治疗不足以恢复线粒体功能。给予IFC - 305可维持和恢复线粒体功能,并调节与代谢相关的参数以及由二乙基亚硝胺中毒引起的线粒体动态变化。这项研究支持IFC - 305作为潜在的肝细胞癌治疗药物或化疗辅助药物。
