Sample GSM449756 Query DataSets for GSM449756
Status Public on Sep 11, 2009
Title HCV+cirrhosis without HCC 18
Sample type RNA
 
Source name liver tissue
Organism Homo sapiens
Characteristics disease state: HCV + cirrhosis without HCC
tissue: liver
Treatment protocol Five mm frozen section slides were made and stained with H&E for Pathologist evaluation to determine tumor content. After Pathologist evaluation, normal/necrotic tissue was macrodissected. Twenty 20 mm sections were performed in a 15 ml tube with 10 ml of Trizol.
Growth protocol Fresh tissue specimens were collected from the consented patients in the operating room and processed immediately after extraction to minimize RNA degradation. Liver tissue samples were collected in liquid nitrogen or RNA later solution (Ambion, Inc, Austin, TX), and stored at -80┬░C until use.
Extracted molecule total RNA
Extraction protocol Trizol extraction of total RNA was performed according to the manufacturer's instructions.The precipitated product was further purified using RNeasy Mini Kit (Qiagen, CA).
Label biotin
Label protocol Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 6 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
 
Hybridization protocol Following fragmentation, 10 ug of cRNA were hybridized for 16 hr at 45C on the Affymetrix GeneChips. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
Scan protocol GeneChips were scanned using GeneChip® Scanner 3000 by Affymetrix.
Description Gene expression using RMA method
Data processing The RMA method in the R affy package was used to obtain probe set expression summaries.
