Burn induces a systemic response affecting multiple organs, including the liver. Since the liver plays a critical role in metabolic, inflammatory, and immune events, a patient with impaired liver often exhibits poor outcomes. The mortality rate after burns in the elderly population is higher than in any other age group, and studies show that the liver of aged animals is more susceptible to injury after burns. Understanding the aged-specific liver response to burns is fundamental to improving health care. Furthermore, no liver-specific therapy exists to treat burn-induced liver damage highlighting a critical gap in burn injury therapeutics. In this study, we analyzed transcriptomics and metabolomics data from the liver of young and aged mice to identify mechanistic pathways and in-silico predict therapeutic targets to prevent or reverse burn-induced liver damage. Our study highlights pathway interactions and master regulators that underlie the differential liver response to burn injury in young and aged animals.
烧伤会引起全身性反应,影响多个器官,包括肝脏。由于肝脏在代谢、炎症和免疫事件中起着关键作用,因此肝功能受损的患者往往预后不良。老年人烧伤后的死亡率高于其他任何年龄段,研究表明,老年动物的肝脏在烧伤后更容易受到损伤。了解烧伤后老年肝脏的特异性反应对于改善医疗保健至关重要。此外,目前尚无针对烧伤引起的肝损伤的肝脏特异性治疗方法,这突显了烧伤损伤治疗学中的一个关键空白。在这项研究中,我们分析了年轻和老年小鼠肝脏的转录组学和代谢组学数据,以确定预防或逆转烧伤引起的肝损伤的机制途径和计算机预测治疗靶点。我们的研究强调了导致年轻和老年动物肝脏对烧伤损伤反应差异的途径相互作用和主要调节因子。
