| Title |
Metastatic prostate tumor samples in para tracheal lymph node from patient EB667 EB667_7EU95C |
| Sample type |
RNA |
| |
|
| Source name |
EB667_7E, metastatic prostate tumor samples in para tracheal lymph node from patient EB667
|
| Organism |
Homo sapiens |
| Characteristics |
Tissue: prostate tumor metastases in paratracheal lymph node
|
| Treatment protocol |
Specimens were received directly from the operating room. Samples (>500 mg) were excised and snap frozen in liquid nitrogen within 30 min of excision and stored at -80°C until extraction of RNA. Metastatic tumor samples were obtained from a warm autopsy program and processed similarly to primary tumors. An H&E stained frozen section of each sample was evaluated by a pathologist, to determine epithelial and stromal content and verify the presence of tumor in the sample. Dissection of the frozen tissue block was performed with the guidance of a marked H & E slide to minimize the presence of host tissue in the metastatic samples. All samples used in the study contained >80% tumor. Metastatic tumor samples were minced and divided into two equal portions to be extracted with the sample protocol used for each set of primary tumors.

| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted with Qiagen Rneasy kit according to the manufacturer's instructions.
|
| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 5 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
|
| |
|
| Hybridization protocol |
Following fragmentation, 15 ug of cRNA were hybridized for 16 hr at 45C on GeneChip HG-U95C array. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
|
| Scan protocol |
GeneChips were scanned using the Affymetrix GeneChip Scanner 3000.
|
| Description |
Gene expression data from metastatic prostate cancer
|
| 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. The trimmed mean target intensity of each array was arbitrarily set to 200.
