摘要: 采用高脂饮食(high fat diet,HFD)诱导的肥胖大鼠模型,探究口服胡椒碱(1-piperoylpiperidine,PIP)对代谢紊乱引发生物钟异常的调控作用。结果表明,PIP减轻了HFD诱导的肝脏损伤,降低了血脂水平,缓解了肝脏生物钟和脂代谢基因的昼夜节律紊乱,恢复了与生物钟密切相关的脂质分子溶血磷脂酸(16:0_18:1)、双甲基磷脂酸(38:8e)、磷脂酰乙醇胺(16:0p_22:6)和甲基磷胆碱(32:4e)的表达水平变化。本研究结果可为PIP调节肝脏脂代谢昼夜节律提供一定的理论依据。

Abstract: In this study, an obese rat model induced by a high-fat diet (HFD) was used to investigate the modulating effect of 1-piperoylpiperidine (PIP) on circadian misalignment caused by metabolic dysregulation. The results showed that PIP attenuated HFD-induced liver injury, lowered blood lipid levels, alleviated circadian rhythm disruptionthe biological clock and lipid metabolism genes in the liver, and restored the changes in the expression of lysophosphatidic acid (16:0_18:1), bis-methyl phosphatidic acid (BisMePA, 38:8e), phosphatidyl ethanolamine (PE, 16:0p_22:6) and methylphosphocholine (MePC, 32:4e), which are closely associated with the biological clock. These findings may provide a theoretical basis for understanding the regulatory effect of PIP on the circadian rhythm of liver lipid metabolism.
