Quantitative Proteomic Analysis of C57BL/6J mice after optic nerve crush Using iTRAQ Labeling

ABSTRACT: We used two groups of C57BL/6J mice, one with optic nerve crush on one eye, and another with no crush as control. Three mice were subjected to optic nerve crush, with sample names 121, 113, 114 and two were used as control with sample names 118 and 119. For the optic nerve crush, a surgical peritomy was made behind and above the eyeball and the eye muscles were gently retracted to expose the optic nerve. Dumont #5 forceps (FST) were used to crush the optic nerve approximately 0.5-1 mm behind the globe without damaging retinal vessels or affecting the blood supply.

Growth cones (GCs) are structures associated with growing neurons. GC membrane expansion, which necessitates protein-lipid interactions, is critical to axonal elongation in development and in adult neuritogenesis. We present a multi-omic analysis that integrates proteomics and lipidomics data for the identification of GC pathways, cell phenotypes, and lipid-protein interactions, with an analytic platform to facilitate the visualization of these data. We combine lipidomic data from GC and adult a ...[more]

Expression data from mouse optic nerve head after optic nerve crush

Project description:Reactive gliosis is a complex process that involves profound changes in gene expression. We used microarray to indentify differentially expressed genes and to investigate the molecular mechanisms of reactive gliosis in optic nerve head in response to optic nerve crush injury. C57Bl/6 female mice were 6-8 weeks old at the time of optic nerve crush surgery. The optic nerve in the left eye was crush 1 mm behind the globe for 10 seconds and the right eye served as contralateral control. The animals were allowed to recover for 1 day, 3 day, 1 week, 3 weeks and 3 months before the optic nerve heads were collected. The naive control mice did not receive any surgery in either eye. Due to the small tissue size of the mouse optic nerve head, two optic nerve heads were pooled together for each microarray chip. The left eyes and the right eyes of two mice were combined respectively to form one pair of experiment and control samples. There were five biological replicates (10 mice) for each condition.

Gene expression timecourse in zebrafish whole eye in response to optic nerve crush

Project description:It is well-established that neurons in the adult mammalian central nervous system are terminally differentiated and, if injured, will be unable to regenerate their connections. In contrast to mammals, zebrafish and other teleosts display a robust neuroregenerative response. Following optic nerve crush (ONX), retinal ganglion cells (RGC) regrow their axons to synapse with topographically correct targets in the optic tectum, such that vision is restored in ~21 days. What accounts for these differences between teleostean and mammalian responses to neural injury is not fully understood. A time course analysis of global gene expression patterns in the zebrafish eye after optic nerve crush can help to elucidate cellular and molecular mechanisms that contribute to a successful neuroregeneration. We used microarrays to detail the global gene expression patterns underlying a successful regeneration or the optic nerve following injury. Experiment Overall Design: Microarray analysis was performed on total RNA extracted from whole eye following optic nerve crush (ONX) or sham surgery at defined intervals (4, 12, & 21 days).

Transcription profiling time series of rat retina after intra-orbital nerve transection, intra-orbital nerve crush or no treatment

Project description:Array experiment: Animals were divided into a control group (naive), which did not undergo any experimental manipulation (n=20) and two experimental groups, one receiving an intra-orbital nerve transection (IONT, n=60) and the other an intra-orbital nerve crush (IONC, n=60) Sterile precautions were maintained for all surgical procedures. The left ON was intraorbitally axotomized according to procedures that are standard in our laboratory. (REF) Briefly, an incision was made in the superior orbital rim, the superoexternal orbital contents were dissected, and the superior and external rectus muscles were removed. When performing IONT, the dura mater was opened longitudinally to spare the blood supply, and the optic nerve was transected 0.5 mm from the optic disc. To perform IONC the optic nerve was crushed 3 mm from the optic disc during 10 seconds using a pair of watchmakers forceps (Vidal-Sanz et al., 1988, 1991; Villegas-Perez et al., 1993). Before and after the procedure, the eye fundus was observed through the operating microscope to assess the integrity of the retinal blood flow. Tissue processing and RNA extraction: Animals were kept the appropriate time post injury (12h, 24h, 48h, 3d 7d and 15d, n=8-12 per time point) and then sacrificed by an intraperitoneal overdose of sodium pentobarbital. Left retinas were fresh dissected and immediately frozen in liquid nitrogen. Four retinas from each time point, animal group and biological replica were pooled and RNA was extracted using Trizol (Invitrogen). RNA was further cleaned through RNAeasy mini kit columns (Quiagen). The RNA integrity was checked using a Bioanalyzer (Agilent Technologies, USA) and concentrations were determined using a NanoDrop (NanoDrop Technologies, Wilmington, DE, USA).

Differential response of C57BL/6J mouse and DBA/2J mouse to optic nerve crush

Project description:Retinal ganglion cell (RGC) death is the final consequence of many blinding diseases, where there is considerable variation in the time course and severity of RGC loss. Indeed, this process appears to be influenced by a wide variety of genetic and environmental factors. In this study we explored the genetic basis for differences in ganglion cell death in two inbred strains of mice. We found that RGCs are more susceptible to death following optic nerve crush in C57BL/6J mice (54% survival) than in DBA2/J mice (62% survival). Using the Illumina Mouse-6 microarray, we identified 1,580 genes with significant change in expression following optic nerve crush in these two strains of mice. Our analysis of the changes occurring after optic nerve crush demonstrated that the greatest amount of change (44% of the variance) was due to the injury itself. This included changes associated with ganglion cell death, reactive gliosis, and abortive regeneration. The second pattern of gene changes (23% of the variance) was primarily related to differences in gene expressions observed between the C57BL/6J and DBA/2J mouse strains. The remaining changes in gene expression represent interactions between the effects of optic nerve crush and the genetic background of the mouse. We extracted one genetic network from this dataset that appears to be related to tissue remodeling. One of the most intriguing sets of changes included members of the crystallin family of genes, which may represent a signature of pathways modulating the susceptibility of cells to death. Differential responses to optic nerve crush between two widely used strains of mice were used to define molecular networks associated with ganglion cell death and reactive gliosis. These results form the basis for our continuing interest in the modifiers of retinal injury. 18 Samples: 9 per strain (C57BL/6J & DBA/2J); 3 conditions per strain
