| Title |
GAS_DIS_ST_YG31N |
| Sample type |
RNA |
| |
|
| Source name |
Primary gastric cancer
|
| Organism |
Homo sapiens |
| Characteristics |
normal surrounding gastric tissue
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated from tissues with mirVana RNA Isolation labeling kit (Ambion Inc) according to the manufacturer's protocol. RNA quality and integrity were confirmed by ExperionTM Automated Electrophoresis System (BIO-RAD)
|
| Label |
Biotin
|
| Label protocol |
Biotin-labeled cRNA samples for hybridization were prepared according to Illumina's recommended sample labeling procedure: 500 ng of total RNA was used for cDNA synthesis, followed by an amplification/labeling step (in vitro transcription) to synthesize biotin-labeled cRNA using the Illumina?? TotalPrep RNA Amplification kit (Ambion Inc., Austin, TX). cRNA concentrations using spectrophotometer (Nanodrop, ND-1000)

|
| Hybridization protocol |
Labeled, amplified material (1,500 ng per array) was hybridized to a ver. 3 of the Illumina Human-6 BeadChip (48K) according to the Manufacturer's instructions (Illumina, Inc., San Diego, CA). Array signals were developed by Amersham fluorolink streptavidin-Cy3 (GE Healthcare Bio-Sciences, Little Chalfont, UK) following the BeadChip manual
|
| Scan protocol |
Arrays were scanned with an Illumina Bead array Reader confocal scanner (BeadStation 500GXDW; Illumina, Inc., San Diego, CA) according to the Manufacturer's instructions
|
| Description |
To export to gene expression data based on unique gene, we used Sample Gene Profile option of Illumina BeadStudio software. The whole 48804 probes on the Human-6 beadChip ver. 3 were used. Clinical data provided as a supplementary file on Series record: GSE13861_GE_MDACC_DepSysB_ClinicalInformation.xls.gz
|
| Data processing |
Array data processing were performed on Illumina BeadStudio software. We normalized gene expression data using Quantile normalization and log2 transformation. To export to a data matrix, Sample Gene Profile option of this software was used.
