Project description:Purpose: compare the gene expression in whole sciatic DRG of aged mice preceding and after sciatic nerve injury (SNI) compared to the young Results: we found ageing-dependent gene expression changes repressing axonal regeneration following sciatic nerve injury
Project description:Sciatic nerve ligation was performed on cohorts of 2-month and 24-month old animals. Resulting gene-expression data were generated from sciatic nerve 1 and 4 days after injury compared to naïve animals. Results show differences in sciatic nerve responses with normal aging. Total RNA taken from sciatic nerves from 2-month and 24-month old animals at either day 0, 1 and 4 after sciatic nerve crush injury.
Project description:ChIP-seq of H3K27acetylation in sham and injured nerve. Schwann cells play an important role in the response of peripheral nerve to injury. This study was designed to identify enhancers that are altered in sciatic nerve at 3 days post-injury to help identify pathways that mediate the gene expression reprogramming that occurs in Schwann cells after nerve injury. We employed ChIP-seq analysis of H3K27 acetylation as a mark of actively engaged enhancers, and compared enhancers in the distal stump of transected sciatic nerve compared to contralateral (sham) condition.
Project description:We used microarrays to distinguish the gene expression differences among different time points after injury. We generated proximal sciatic nerve (SN) tissues (0.5cm) at 0h, 0.5h, 1h, 3h, 6h and 9h after sciatic nerve resection.

Project description:Analysis of gene expression in injured primary DRG with or without camptothecin (CPT) treatment after sciatic nerve crushing may help us identify critical molecular pathways related to axon regeneration. We performed RNA-sequencing of (i) Naive primary DRG tissues without injury, (ii) Primary DRG tissues with vehicle treatment different time-points (18, 24, 36 hours) after sciatic nerve injury, and (iii) Primary DRG tissues with camptothecin treatment different time-points (18, 24, 36 hours) after sciatic nerve injury.
