摘要: 围产期奶牛经历不同程度的能量负平衡状态,严重的能量负平衡导致奶牛酮病,血液酮体浓度异常升高,降低奶牛的生产性能,并且常发生炎症性疾病。β-羟丁酸(β-hydroxybutyrate,BHBA)是主要的酮体分子,BHBA不仅可以作为能量物质供能,还能够介导表观遗传修饰调控基因转录表达,也能够作为信号分子与相应的受体结合,调控炎症反应。BHBA将外界环境变化与细胞功能改变联系起来,影响疾病进程。本文从BHBA信号传导角度进行综述,重点阐述BHBA影响表观遗传修饰改变基因转录调控,探讨了对炎症反应调节的分子机制,以期为代谢与炎症的研究提供新思路。

Abstract: Dairy cows experience varying degrees of negative energy balance during the perinatal period. Severe negative energy balance leads to ketosis, abnormally elevated blood ketone body concentration, reduced performance, and often inflammatory diseases in dairy cows. β-hydroxybutyrate (BHBA) is a major ketone molecule. BHBA not only acts as an energy source, but also mediates epigenetic modifications that regulate gene transcription and expression, and can act as a signaling molecule that binds to the corresponding receptor to regulate the inflammatory response. BHBA links changes in the external environment to changes in cell function and affects disease processes. This review of BHBA signal transduction focuses on the effect of BHBA on epigenetic modification to alter gene transcription regulation, and explores the molecular mechanisms of BHBA in the regulation of inflammatory response, with the aim of providing new ideas for the study of metabolism and inflammation.

Key words: β-hydroxybutyrate, epigenetic modification, inflammation, metabolism
