Project description:Excerpt from a larger study which characterized the transcriptional effects of a spinal cord contusion injury in rats. This is the data from the almost chronic contusion state (35 days) at the injury site (Thoracic 8) - where we saw significant changes in several areas, including cholesterol metabolism genes. Other spinal cord areas (rostral, caudal) and time-points (3 hours, 24 hours, 7 days and 35 days) were analyzed as well and are discussed in our paper and at www.crpf.org/microarray.

Project description:To determine whether the expression levels of circular RNAs were altered and lay a foundation for future work, we used high-throughput microarray analysis to screen circular RNAs expression patterns in the spinal cord of adult rats after traumatic spinal cord injury (SCI), finally to evaluate the potential rat models as a platform for the development of novel therapeutic targets for spinal cord injury in future clinical studies. Overall six rats at 3 days post-SCI in two groups were used to perform the microarray.

Project description:Purpose: The goal of this study was to determine the gene expression changes that occur over 7 days in parralyzed muscle in response to isometric contraction elicited by electrical stimulation initiated 4 months after spinal cord injury and to compare such changes to those observed in a normal muscle subjected to overload. Methods: Electrical stimulation of the soleus and plantaris muscle was stimulated in female rats with complete transection of the spinal cord at the interspace between the 9th and 10th thoracic vertebrae. Stimulation was begun 16 weeks after spinal cord transection and produced near-isometric contraction of soleus, plantaris and tibialis anterior. Muscle was analyzed at 1, 2 and 7 days after starting exercise with electrical stimulation. To provide a baseline reference for gene expression at 16 weeks after spinal cord injury, muscle was also analysed from an additional group of spinal cord transected animals. One additional group of animals with a sham-spinal cord injury was included to provide information about gene expression in neurologically intact animals of similar age. In parallel studies, rats underwent bilateral gastrocnemius ablation to overload soleus and plantaris, or a sham ablation as a control. Muscle was analyzed at 1, 3 and 7 days after gastrocnemius ablation or sham-ablation. Gene expression was determined using Affymetrix Rat Exon microarrays. For each group of animals, microarray analysis was performed for soleus muscle for each of 3 separate animals, using one array per animal. Control sammples for the spinal cord injured groups included a group of animals with a Sham-spinal cord injury, and a group of spinal cord injured animals that did not get electrical stimulation. The comparator for determining fold-change expression values was the spinal cord injured group that did not receive electrical stimulation. For each day after gastrocnemius ablation, a control was included that received all procedures needed for this ablation except cutting the distal insertion of the gastrocnemius into the Achilles tendon to control for effects of the surgery on gene expression.

Project description:We analyzed the changes in the spinal cord transcriptome after a spinal cord contusion injury and MSC or OEC transplantation. The cells were injected immediately or 7 days after the injury. The mRNA of the spinal cord injured segment was extracted and analyzed by microarray at 2 and 7 days after cell grafting.

Project description:Hyperbaric oxygen (HBO) therapy is frequently used to treat peripheral wounds or decompression sickness. Evidence suggests that HBO therapy can provide neuroprotection and has an anti-inflammatory impact after neurologic injury including spinal cord injury (SCI). Our primary purpose was to conduct an unbiased, genome-wide screening of mRNA expression changes in the injured spinal cord after HBO therapy. A mRNA gene array was used to evaluate samples taken from the contused region of the spinal cord following a lateralized mid-cervical contusion injury in adult female rats. HBO therapy consisted of daily, 1-hour sessions (3.0 ATA, 100% O2) initiated on the day of SCI. Gene set enrichment analyses indicated that HBO upregulated genes in pathways associated with electron transport, mitochondrial function, and oxidative phosphorylation, and downregulation genes in pathways associated with inflammation (including cytokines and NF-B) and apoptotic signaling. In a separate cohort, spinal cord histology was performed to verify whether the HBO treatment impacted neuronal cell counts or inflammatory markers. Compared to untreated rats, there was increased NeuN positive cells in the spinal cord of HBO treated rats (p=0.007). Further, staining for anti-ionized calcium binding adaptor protein (Iba-1, a microglial marker) was reduced after HBO (p=0.028). We conclude that HBO therapy, initiated shortly after SCI and continued for 10-days, can alter the molecular signature of the lesioned spinal cord in a manner consistent with an anti-inflammatory and neuroprotective impact.

Project description:Patients carrying one or two ApoE4 alleles suffer from worse functional recovery after spinal cord injury. Using transgenic mice expression human ApoE3 or ApoE4 we investigated potential cellular mechanisms of reduced recovery after spinal cord injury. Bulk RNA sequencing of the spinal cord lesion site followed by pathway enrichment analysis predicts that ApoE4 mice have a higher inflammatory and extracellular matrix remodeling activity 7 days after spinal cord injury. Contrary, higher activities for neuronal projection and action potential patways were predicted in the ApoE3 mice at 21 days after 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.
