| Title |
Animal 11 |
| Sample type |
RNA |
| |
|
| Source name |
Left ventricle, sham surgery, saturated fat diet
|
| Organism |
Rattus norvegicus |
| Characteristics |
strain: Wistar
gender: male
tissue: left ventricle
surgery: sham
coronary status: normal
diet: high saturated fat
|
| Treatment protocol |
Rats were randomly assigned to receive either a sham-operation (SH) or coronary ligation to induce cardiac dysfunction (HF). Following surgery, rats were immediately fed either a normal rodent chow (NC) or a high saturated fat chow (SAT) with 60% caloric content derived from fat (25% palmitic, 33% stearic, 33% oleic acid, Research Diets).
|
| Growth protocol |
Tissue from a separate set of animals (n=6/group) was quick frozen in liquid nitrogen for microarray analysis.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was extracted from all tissues using a standard protocol and Tri-reagent.
|
| Label |
Cy3
|
| Label protocol |
Total RNA was converted to cDNA by reverse transcription using Superscript II reverse transcriptase and T7-(dT)24 primers, followed by second-strand synthesis to generate double-stranded cDNA.
|
| |
|
| Hybridization protocol |
A total of 0.75 micrograms of biotin-labeled cRNA was applied to a BeadChip and allowed to hybridize overnight at 55°C for approximately 18 hours, followed by washing and staining with streptavidin-Cy3 prior to visualization.
|
| Scan protocol |
BeadChips were visualized using the BeadStation scanner, which uses a dual-laser confocal scanner with 0.8 µm resolution to determine fluorescence values for each bead on the chip.
|
| Description |
Approximately 22,000 RefSeq and EST transcripts are present on the arrays in the form of oligo-coated (50mer) beads.
INF11_SHAM_SAT
|
| Data processing |
After scanning the probe arrays, the resulting images were analyzed using the BeadStudio software (V3, Illumina, Inc., San Diego, CA), which calculates the mean fluorescence signal across all replicates of each gene/transcript, along with a probability that the mean signal for each gene/transcript on the chip is greater than background (i.e., detection p-value). Both non-normalized and normalized (quantile) data were generated for each sample.
