Summary: | 采用超高效液相色谱-四极杆-飞行时间质谱(UPLC-Q-TOF-MS)技术,结合多元变量数据分析方法,研究0.1%褐藻糖胶喂养黄颡鱼幼鱼1~8周的脂质代谢组学。通过不同喂养时间的黄颡鱼脂质成分的重要性(VIP)值和差异性(P)值,筛选出98个差异性代谢物,其中鉴定出与褐藻糖胶对黄颡鱼随喂养时间变化的影响有重要作用的11种脂质生物标志物,包括Lyso-PC 16:0、PC 22:6/16:0、PE 22:6/16:0、PI 18:0/22:6、DAG 16:0/16:0、DAG 16:0/18:1、DAG 18:1/18:1、TAG 20:5/16:0/18:3、TAG 20:4/16:1/18:2、TAG 16:0/18:2/20:5和TAG 18:2/14:0/18:1。研究表明,经0.1%褐藻糖胶喂养不同时期的黄颡鱼中Lyso-PC、PC、PE和PI的含量在第8周时达到最大值;DAG的含量呈现出先减少后增加的变化规律,而TAG的变化不定,TAG 18:2/14:0/18:1、TAG 20:5/16:0/18:3和TAG 20:4/16:1/18:2的含量随着喂养褐藻糖胶时间的延长而增加,而TAG 16:0/18:2/20:5呈减少的趋势。根据上述实验结果,推测褐藻糖胶可能通过调节脂质成分的含量来增加黄颡鱼幼鱼的免疫力。本研究结果为褐藻糖胶对黄颡鱼脂质代谢响应机理的影响的研究提供理论依据。 |

Bibliography: | Pelteoobagrus fulvidraco; Fucoidan; Ultra-performance liquid chromatography- quadrupole- time- of- flight-mass spectrometry; Lipidomic 22-1125/O6 The effects of fucoidan on the lipidomics profiling of juvenile yellow catfish (pelteobagrus fulvidraco) during different feeding time ( week 1, week 2, week 3 and week 8) were investigated by ultra-performance liquid chromatography- quadrupole- time- of- flight-mass spectrometry ( UPLC- Q- TOF-MS ) combined with multivariate data analysis, e. g. principal component analysis (PCA) and partial least squares- discriminate analysis (PLS-DA). Based on VIP and p values, 11 lipid biomarkers were screened including lysophosphatidylcholine ( Lyso- PC) 16: 0, phosphatidylcholine (PC) 22:6/16: 0, phosphatidylethanolamine (PE) 22: 6/16: 0 , phosphatidylinositol ( PI) 18 : 0/22: 6 , diacylglycerol ( DAG) 16: 0/16 : 0 , DAG 16: 0/ 18:1,DAG 18:1/18:1,triglycerides (TAG) 20:5/16:0/18:3, TAG 20:4/16:1/18:2, TAG 16:0/18:2/ 20:5 and TAG 18:2 2/14:0 0/18: 1.
