| Title |
Naive+ GPN L4 DRG,Contra set C |
| Sample type |
RNA |
| |
|
| Source name |
Rat L4 dorsal root ganglia (DRG), contralateral (contra) to the injury.
|
| Organism |
Rattus norvegicus |
| Characteristics |
rats from five experimental groups were sacrificed 19–21 days after surgery
|
| Treatment protocol |
Rats having the L5-L6 spinal nerves ligated (SNL) were performed, Sham-operation consisted of exposing the spinal nerves without ligation or manipulation. Naïve animals did not receive surgery.Rats were tested before and 12–14 days after surgery. Only SNL rats exhibiting a significantly reduced PWT in the ipsilateral limb were included in drug testing or gene expression studies (eight to twelve rats per group). Vehicle (0.9% saline) or gabapentin (GPN; 100 mg/kg dissolved in 0.9% saline) was administered intraperitoneally (i.p.) once a day for 7 days in a volume of 2 ml/kg. On the last (7th) treatment day (corresponding to 19–21 days post-surgery), rats were again assessed by PWT, in particular to confirm the reversal of neuropathic pain with GPN treatment.

| Growth protocol |
For gene expression analysis, rats from five experimental groups were sacrificed 19–21 days after surgery
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Trizol extraction of total RNA was performed according to the manufacturer's instructions.
|
| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol (Expression Analysis Technical Manual, 2001, Affymetrix).
|
| |
|
| Hybridization protocol |
Following fragmentation, 10 ug of cRNA were hybridized for 16 hr at 45C on GeneChip Drosophila Genome Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
|
| Scan protocol |
GeneChips were scanned using the Hewlett-Packard GeneArray Scanner G2500A.
|
| Description |
Gene expression data
|
| Data processing |
The data were analyzed with Microarray Suite version 5.0 (MAS 5.0) using Affymetrix default analysis settings and global scaling as normalization method.
