Lipidomics Dataset of Sonication-Induced Traumatic Optic Neuropathy in Mice

ABSTRACT: Traumatic optic neuropathy (TON) is the loss of vision secondary to trauma. Approximately two weeks after traumatic damage, diffuse retinal ganglion cell loss and axon degeneration of the optic nerve are exhibited. Here we present the changes that occur in the optic nerve lipidome of two-month-old C57BL/6J mice following sonication-induced TON (SI-TON), which closely models the indirect clinical mechanism in TON. Optic nerves were harvested at three time points following injury: 1-day, 7-days, and 14-days for comparison with the control group (uninjured optic nerves from 2-month-old mice). Lipidomic changes were observed at each of the various time points, with a pattern of progression present in multiple lipid classes. This data demonstrates the distinct lipidomic changes at each time point following indirect trauma to the optic nerve.

EAE Optic Nerves Injected with LPC 18:1 + Isobaric C13-His

Project description:EAE mice were injected with LPC 18:1 and Isobaric C13-His at the optic nerve when they exhibited a clinical score of 2. Visual function was assessed via pattern electroretinogram and optic nerves were harvested 12 days post optic nerve injection. Optic nerves were processed for mass spectrometry to identify the integration of C13-His in newly synthesized proteins.

Labeled quantitative proteomics dataset of optogenetics induced axon regeneration

Project description:This labeled quantitative proteomics dataset was collected from a transgenic channel rhodopsin mouse model (Chr2) subjected to light stimulation after traumatic optic nerve crush (ONC) was performed. Mouse models expressing channel rhodopsin were subjected to therapeutic light stimulation promoting axon regeneration of retinal ganglion cell (RGC) axons post optic nerve crush. Experimental mice and wild type control mice were euthanized, and optic nerves were collected. A protein extraction was carried out by careful mincing of the tissue in extraction buffer (TEAB, NaCl and SDS). Protein amount normalization across samples was achieved using dot blot densitometry using ImageJ software. Samples were labelled using a modified 16plex TMT (Tandem Mass Tag) kit for quantification after overnight trypsin digestion. Untargeted liquid chromatography-mass spectrometry was performed on an Easy-nLC 1000 liquid chromatograph coupled to a QExactive mass spectrometer (LC-MS/MS). Data analysis was performed using Proteome Discoverer 2.5.

Expression data from P4 and P10 mouse optic nerves

Project description:Optic nerves are an accessible part of the CNS, providing a source of glia without the presence of neuronal cell bodies. Therefore, an analysis was carried out of gene expression in optic nerves at P4, before myelination begins and at P10, when myelination is very actively proceeding. The goal was to obtain a profile of the changing gene expression that accompanies this transition from unmyelinated CNS nerve to myelinated nerve. Two microarray experiments were combined here. In the first, RNA was prepared from the optic nerves of 75 P4 C57BL/6J mice and 70 P10 C57BL/6J mice. In the second experiment, RNA was prepared from the optic nerves of 55 P4 C57BL/6J mice and two groups of 50 P10 C57Bl/6J mice. In total, there are 2 P4 RNA samples and 3 P10 RNA samples being hybridized to Affymetrix GeneChip 430A for Mouse Expression.

EAE Optic Nerve Injections with LPC 18:1 (iTRAQ)

Project description:EAE mice were injected with LPC 18:1 at the optic nerve when they exhibited a clinical score of 2. Visual function was assessed via pattern electroretinogram and optic nerves were harvested 12 days post optic nerve injection. Three different visual recovery pathways were observed: 1) No-injection control (no recovery in visual function), 2) Low recovery visual function, 3) High recovery visual function and 4) No change in visual function.

Retinal whole genome microarray analysis after irradiated injury of intraorbital nerve in the monkey

Project description:To obtain and analyze early retinal changes at molecular level at 24h after ipsilateral intraorbital nerve radiation injury by gamma knife surgery Unilateral intraorbital optic nerves of three Rhesus Macaques were treated by gamma knife surgery (GKS) with irradiated doses of 15Gy, while the contralateral optic nerves and retinas served as the control. Gene expression profiles of control and affected retinas were analyzed with Affymetrix Rhesus Macaque Genome arrays at 24h after treatment

Differential gene expression in Danio rerio during optic nerve regeneration

Project description:To gain a better understanding of the factors necessary for successful CNS regeneration, a temporal analysis of the changes in gene expression in the eye caused by optic nerve injury was conducted. Dual color oligonucleotide microarrays were used to compare total RNA harvested from the eyes of sham-operated and optic nerve-injured fish at 3, 24, and 168 hours following surgery. Optic nerve injured fish are compared to sham-operated fish in order to eliminate gene expression due to non-neuronal damage and inflammatory response. Statistical analyses identified 131 genes with a 2.0-fold or greater difference in expression. Wild type zebrafish were obtained from a local pet store. Optic nerve injury was conducted using a severing model accomplished as follows. Zebrafish were anesthetized in 0.2% MS-222 dissolved in tank water. The muscles surrounding the eye were cut and the eye angled rostrally to expose the nerve. The optic nerve was then severed using microsissors without damaging the ophthalmic artery. In sham operated fish the muscles surrounding the eye were severed but the nerve was not damaged. RNA was extracted from the eye at three time points following surgery 3 hours, 24 hours, and 168 hours. RNA was pooled from multiple fish to achieve 10 ug total RNA. Samples were collected in triplicate per time point. Gene expression was analyzed on a dual color oligonucleotide array where the optic nerve injured fish were compared to sham-operated fish. Four samples of RNA were also collected from control fish and compared to each other on the microarray to confirm that processing did not create expression differences.

Aldose reductase inhibition decelerates optic nerve degeneration by suppressing retinal microglia activation

Project description:To investigate the role of aldose reductase (AR) inhibition using Sorbinil on retinal microglia (RMG) activation, retinal ganglion cell (RGC) survival, and axon regeneration after optic nerve trauma. We observed that AR inhibition using Sorbinil attenuates RMG activation and subsequently promotes RGC survival and delays axon degeneration one week after optic nerve crush.
