Traumatic optic neuropathy (TON) is a degenerative process that occurs in a subset of patients following blunt force trauma to the head. This condition is characterized by retinal ganglion cell (RGC) death and axon degeneration within the optic nerve [1]. At the cellular level, mitochondrial changes are associated with many optic neuropathies [2, 3]. Here, we provide a dataset demonstrating changes in the optic nerve mitochondrial lipid profile of a sonication-induced traumatic optic neuropathy (SI-TON) mouse model at 1, 7, and 14 days after injury. 32 C57BL/6J mice were separated into 4 groups (control, 1, 7, and 14 days) of 8, with 4 males and 4 females in each. Mice were exposed to sonication-induced trauma as described previously (by Tao et al) and optic nerves were harvested at 1, 7, or 14 days following injury [4]. Mitochondria were isolated from homogenized optic nerves and lipids were extracted. Extracted mitochondrial lipids were analysed with a Q-Exactive Orbitrap Liquid Chromatography-Mass Spectrometer (LC MS-MS). Further analysis of raw data was conducted with LipidSearch 4.1.3 and Metaboanalyst 4.0. This data is publicly available at the Metabolomics Workbench, http://www.metabolomicsworkbench.org (Project ID: PR000905).
创伤性视神经病变(TON)是一种在头部受到钝性外力创伤的部分患者中发生的退行性过程。这种病症的特征是视网膜神经节细胞(RGC)死亡以及视神经内的轴突退化[1]。在细胞水平上,线粒体变化与许多视神经病变相关[2,3]。在此,我们提供了一个数据集,展示了超声诱导的创伤性视神经病变(SI-TON)小鼠模型在损伤后1天、7天和14天时视神经线粒体脂质谱的变化。32只C57BL/6J小鼠被分成4组(对照组、1天组、7天组和14天组),每组8只,每组中有4只雄性和4只雌性。小鼠如先前所述(由Tao等人)接受超声诱导的创伤,并在损伤后1天、7天或14天采集视神经[4]。从匀浆的视神经中分离出线粒体并提取脂质。用Q-Exactive Orbitrap液相色谱-质谱仪(LC MS-MS)分析提取的线粒体脂质。用LipidSearch 4.1.3和Metaboanalyst 4.0对原始数据进行进一步分析。该数据可在代谢组学工作台(http://www.metabolomicsworkbench.org)上公开获取(项目编号:PR000905)。
