Chronic Gene Expression after Traumatic Brain Injury

Project description:This project continues our acute TBI studies and initiates chronic studies -- characterizing the temporal genomic profile of the injured brain up to 12 months post-TBI. Thus, the primary objective of this proposal is to determine the long-term effects of traumatic brain injury on gene expression in the hippocampus and cortex, two brain regions known to be particularly vulnerable to TBI.

Gene expression profiles after traumatic brain injury

Project description:Time dependent-profiles in the gene expression level following lateral moderate fluid percussion injury in the rat brain We used microarray to elucidate relationship between the alteration of gene expression levels and the progression of brain damages following traumatic brain injury. To examine the levels of gene expression in the early phase of traumatic brain injury, we analyzed the gene expression at 3, 6, 12, and 48 h after trauma using the lateral moderate fluid percussion TBI model. The ratios of the gene expression level were compared between chips corresponding to the 3, 6 and 12 h fluid percussion groups and the sham group chips. On the other hand, the rations of gene expression level after 48 h FPI were compared with 48 h sham chip, because the gene expression levels of 48 h sham chip were distinct from sham group chips (3, 6 and 12 h) in the cluster and principal components analyses.

Comprehensive analysis of circRNA expression profiles in rat cerebral cortex after moderate traumatic brain injury

Project description:Background: Traumatic brain injury is a medical event of global concern, and a growing body of research suggests that circular RNA can play very important roles in traumatic brain injury. To explore the functions of more novel and valuable circular RNA in traumatic brain injury response, a moderate traumatic brain injury in rat was established and a comprehensive analysis of circular RNA expression profiles in rat cerebral cortex was done. Results: As a result, 301 up-regulated and 284 down-regulated circular RNAs were obtained in moderate traumatic brain injury rats, the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were performed based on the circular RNA’s host genes, and a circRNA-miRNA interaction network based on differentially expressed circular RNAs was constructed. Also, four circular RNAs were validated by RT-qPCR and sanger sequencing. Conclusion: This study showed that differentially expressed circular RNAs existed between rat cerebral cortex after moderate traumatic brain injury and control. And this will provide valuable information for circular RNA research in the field of traumatic brain injury.

Cortical neuropathology RNA expression time-course after diffuse traumatic brain injury

Project description:Traumatic brain injury (TBI) can lead to significant neuropsychiatric problems and neurodegenerative pathologies, which develop and persist years after injury. Neuroinflammatory processes evolve over this same period. Therefore, we aimed to determine the contribution of microglia to neuropathology at acute (1-day post-injury; dpi), subacute (7 dpi), and chronic (30 dpi) time-points. Microglia were depleted with PLX5622, a CSF1R antagonist, prior to midline fluid percussion injury in male mice and cortical neuropathology/inflammation was assessed using a neuropathology mRNA panel. NanoString Neuropathology gene expression panel was used to quantify expression from RNA microdissected from the mouse cortex.

Effect of traumatic brain injury on gene expression in bone.

Project description:It is clinically known, that patients often develop osteoporosis following traumatic brain injury (TBI). To enable a better understanding of the underlying mechanism, we developed a murine TBI model. Mice received a controlled cortical impact inducing a TBI. Expression analysis of the femur 3 days following the injury should reveal the regulated genes. We observed a strong downregulation of osteoblast genes, suggesting an inhibition of bone formation. Furthermore, the beta2-adrenoreceptor was downregulated, what is supposed to be induced by the increased adrenergic signaling in these mice.
