The optic nerve is part of the mammalian adult central nervous system (CNS) and has limited capability to regenerate after injury. Deletion of phosphatase and tensin homolog (PTEN), a negative regulator of the PI3 kinase/Akt pathway, has been shown to promote regeneration in retinal ganglion cells (RGCs) after optic nerve injury [1]. We present the lipidome of adult PTENloxP/loxP mice subjected to intravitreal injection of adeno-associated viruses expressing Cre (AAV-Cre) as a model of CNS neuroregeneration. At 4 weeks old, PTENloxP/loxP mice were intravitreally-injected with 2–3 μl of either AAV-Cre (KO) or AAV-PLAP (control), and two weeks later optic nerve crush was performed. At indicated time-points after crush (0 days, 7 days, 14 days), mice were euthanized and optic nerves were immediately dissected out, and then flash frozen on dry ice. A modified Bligh and Dyer [2] method was used for lipid extraction from the optic nerves, followed by liquid chromatography-mass spectrometry (LC MS-MS) lipid profiling using a Q-Exactive Orbitrap instrument coupled with Accela 600 HPLC. The raw scans were analysed with LipidSearch 4.2 and the statistical analysis was conducted through Metaboanalyst 4.0. This data is available at Metabolomics Workbench, study ID ST001477.
