Genome wide analysis of upper spinal cords with training after spinal cord hemisection injury

Project description:The goal of this study is to elucidate the influence of treadmill training on transcriptome of the upper lumbar spinal cord after thoracic spinal cord hemisection. mRNA profiles of spinal cords at 23 days-post injury with/without treadmill training were generated. The expression levels of 650 genes in the trained animal were increased ( > 2-fold) compared to untrained animals. Our study represents the detailed analysis of transcriptomes of spinal cord distal to the hemisected lesion after treadmill training, with biologic replicates, generated by RNA-seq technology.

Genome wide analysis of the upper lumbar spinal cord at 4 days after T9 hemisection injury

Project description:The goal of this study is to elucidate the influence of hemisection injury at thoracic spinal cord (T9) on the upper transcriptome of the upper lumbar spinal cord at acute phase. mRNA profiles of spinal cord at 4 days-post injury and before injury were generated. 72 Differentially Expressed Genes (DEGs) were observed. Our study represents the detailed analysis of transcriptomes of spinal cord distal to the hemisected lesion at acute phase, with biologic replicates, generated by RNA-seq technology.

Gene expression profiles in the spinal cord below the lesion level and influence of treadmill locomotor training

Project description:Traumatic spinal cord injury (SCI) often leads to loss of locomotor function. Neuroplasticity of spinal circuitry underlies some functional recovery and therefore represents a therapeutic target to improve locomotor function following SCI. However, the cellular and molecular mechanisms mediating neuroplasticity below the lesion level are not fully understood. The present study performed a gene expression profiling in the rat lumbar spinal cord at 1 and 3 weeks after contusive SCI at T9 compared to control rat that received sham injury (laminectomy). The below-level gene expression profiles were compared with those of animals that were subjected to treadmill locomotor training. Rat lumbar spinal cords were taken for the microarray analysis at 1 and 3 weeks after contusive spinal cord injury at the T9 level. Another group of rats received treadmill locomotor training for 3 weeks, and theirs spinal cords were harvested for the microarray. The changes in gene expression after spinal cord injury were analyzed at the two time points. The influence of treadmill locomotor training was evaluated by comparing gene expression profiles between animals with or without treadmill training.

Differential Response Following Spinal Cord Injury in EphA4 Knockout

Project description:Mice lacking the developmental axon guidance molecule EphA4 have previously been shown to exhibit extensive axonal regeneration and functional recovery following spinal cord injury. To assess mechanisms by which EphA4 may modify the response to neural injury, a microarray was performed on spinal cord tissue from mice with spinal cord injury and sham injured controls. RNA was purified from spinal cords of adult EphA4 knockout and wild-type mice four days following lumbar spinal cord hemisection or laminectomy only and was hybridised to Affymetrix All-Exon Array 1.0 GeneChips. While subsequent analyses indicated that several pathways were altered in EphA4 knockout mice, of particular interest was the attenuated or otherwise altered expression of a number of inflammatory genes, including Arginase 1, expression of which was lower in injured EphA4 knockout compared to wild-type mice. Immunohistological analyses of different cellular components of the immune response were then performed in injured EphA4 knockout and wild-type spinal cords. While numbers of infiltrating CD3+ T cells were low in the hemisection model, a robust CD11b+ macrophage / microglial response was observed post-injury. There was no difference in the overall number or spread of macrophages / activated microglia in injured EphA4 knockout compared to wild-type spinal cords at two, four or fourteen days post-injury, however a lower proportion of Arginase-1 immunoreactive macrophages / activated microglia was observed in EphA4 knockout spinal cords at four days post-injury. Subtle alterations in the neuroinflammatory response in injured EphA4 knockout spinal cords may contribute to the regeneration and recovery observed in these mice following injury. Comparison was made between gene expression in wild-type and knockout samples both before and after injury. 3 replicates per group.

Genome wide analysis of thoracic spinal cord at 5 days after T9 hemisection injury.

Project description:The goal of this study is to elucidate the influence of hemisection injury at thoracic spinal cord (T9) and epidural electrical spinal stimulation (L2-S1) on transcriptome of injured thoracic spinal cord. mRNA profiles of spinal cord at 5 days-post injury with or without epidural electrical spinal stimulation (L2-S1) and before injury were generated. Our study represents the detailed analysis of transcriptomes of injured spinal cord with biologic replicates, generated by RNA-seq technology.
