Sample GSM2428103 Query DataSets for GSM2428103
Status Public on Feb 16, 2018
Title Sham control baseline [Sham_3]
Sample type RNA
 
Source name Hippocampus LCM Neurons, sham injury, 2wk, pool from 3 animals
Organism Rattus norvegicus
Characteristics strain: Sprague-Dawley
received: sham injury
treated with: none
time point: 2 weeks post-treatment
tissue: Hippocampus LCM Neurons
Treatment protocol All AAV viral constructs were produced by Vector Biolabs. 3 siRNA sequences targeted to either nNOS or GPX-1 were cloned into the AAV2/1 viral backbone. siRNA oligos were purchased from Ambion and were tested in a neuronal cell culture model to verify gene expression knockdown before providing Vector Biolabs with the sequences for virus production.
Rats received either sham injury, TBI, or TBI + AAV virus (scrambled control virus or nNOS or GPx-1 siRNA constructs) which were stereotaxically injected into the CA1/2 and CA3 regions of the hippocampus. Rats were survived for 15 days, sacrificed, brains were removed and frozen on dry ice. Coronal sections of the brain were collected on glass slides and pyramidal neurons from the CA1/2 and CA3 regions of the hippocampus that expressed the AAV virus were collected by laser capture microdissection.
Extracted molecule total RNA
Extraction protocol Total RNA from laser captured hippocampal neurons was isolated and DNase treated prior to microarray analysis.
Label Alexa 555
Label protocol 2 rounds of amplification were performed using the Arcturus RiboAmp HS kit. Biotinylated cRNA target was prepared from the DNA template purified after the second round cDNA synthesis. cRNA quality was verified on an Agilent Bioanalyzer cRNA was fragmented to uniform size and verified on the Bioanalyzer.
 
Hybridization protocol 10 µg of purified cRNA was fragmented to uniform size and applied to CodeLink Rat Whole Genome Microarrays in hybridization buffer. Arrays were hybridized at 37° C for 18 hrs. in a shaking incubator, and washed at 46° C for 1 hr.
Scan protocol Rinsed and dried arrays were scanned with an Axon GenePix 4000B Microarray Scanner at 5 µm resolution.
Data processing CodeLink software was used to process the scanned images from arrays (gridding and feature intensity extraction) and the data generated for each probe on the array was analyzed with GeneSpring GX v7.3.1 software (Agilent Technologies, Santa Clara, CA).
