| Title |
Hippocampi DBS replicate 2 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
Hippocampi of stimulated rats
|
| Organism |
Rattus norvegicus |
| Characteristics |
treatment: deep brain stimulation
sample type: Male albino Wistar rats.
gender: male
strain: albino Wistar
age: 12 weeks old.
tissue: Hippocampi dissected from slices between Bregma levels -2 and -4.
pool: Pooled from three rats.
|
| Treatment protocol |
Vetrolateral thalamus stimulation 1 hour daily during 14 days
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Tissues were conserved in RNA later (Ambion, Austin, TX) for 48 h at 4ºC. Total RNAs were prepared with an RNeasy Lipid Tissue Mini kit according to manufacturer’s protocol (Quiagen, Valencia, CA)
|
| Label |
Cy5
|
| Label protocol |
500 ng of total RNA from each sample were amplified by Oligo-dT-T7 reverse transcription and labeled by in vitro transcription with T7 RNA polymerase in the presence of Cy5-CTP or Cy3-CTP using the Low Input RNA labeling kit (Agilent) and purified using RNAeasy columns (Qiagen, Hilden, Germany)

|
| Channel 2 |
| Source name |
Brain tissue of reference
|
| Organism |
Rattus norvegicus |
| Characteristics |
sample type: Male albino Wistar rats.
strain: albino Wistar
age: 12 weeks old.
tissue: Brain pooled tissue consisting of hippocampal, thalamic and cortical brain tissue.
pool: Pooling: naive (n=4), sham-operated (n=5) and stimulated (n=4) rats

| Label protocol |

| |
| Hybridization protocol |
After fragmentation, 825 ng of labeled cRNA from each of the two samples were co-hybridized in in situ hybridization buffer (Agilent) for 17 h at 65ºC and washed at rt 1 min in 6X SSPE (Saline Sodium Phosphate-EDTA) pH 7.4 + 0.005% Sarcosine, 1 min at rt in Gene Expression WashBuffer 1 (GE WB1 - Agilent), 1 min at 37 ºC with GE WB2 (Agilent).
|
| Scan protocol |
Scanned on an Agilent G2565AA scanner.
Quantified using GenePix 6.0 (Molecular Devices-MDS Analytical Technologies, Silicon Valley, CA). The quality of each individual hybridization was assessed with the Feature Extraction software 10.5 (Agilent).
|
| Description |
Biological replicate 2 of 4. Hippocampi of stimulated rats versus brain tissue pool of reference.
|
| Data processing |
Raw data was corrected for background noise using the normexp method. Global Lowess normalization was applied (intra-chip normalization). Scaling of the normalized log2 ratios (inter-chip normalization) was applied to assure comparability across samples.
