Sample GSM157912 Query DataSets for GSM157912
Status Public on Jan 14, 2008
Title Hepatocellular carcinoma (HCC), venous metastasis, 278A
Sample type RNA
 
Source name 03-278A
Organism Homo sapiens
Characteristics Tissue: liver tissue (tumor)
Disease state: Hepatocellular carcinoma (HCC), venous metastasis
Individual: 03-278A
Clinical info: Follow up status: dead
Extracted molecule total RNA
Extraction protocol Tri-Reagent Protocol
Other: Total RNA isolation was performed using the Tri-Reagent Protocol (Molecular Research Center, Cincinnati)
Label alexa 647
Label protocol Labeling Protocol
Other: Processed by using a method of direct detection of the biotin-containing transcripts by streptavidin-Alexa647 conjugate.
 
Hybridization protocol Sample Hybridization Protocol
Qty. of labeled target: 5 ug of total RNA
Other: Labeled targets from 5ug of total RNA were used for hybridization on each miRNA microarray chip containing human and mouse miRNA genes. All probes on these microarrays are 40-mer oligonucleotides spotted by contacting technologies and covalently attached to a polymeric matrix. The microarrays were hybridized in 6x SSPE (0.9 M NaCl / 60 mM NaH2PO4 H20 / 8 mM EDTA, pH 7.4) / 30% formamide at 25C for 18 hr, washed in 0.75x TNT (Tris HCL/NaCl/Tween 20) at 37C for 40 min.
Scan protocol Scanning Protocol
Other: Processed slides were scanned by using a PerkinElmer ScanArray XL5K Scanner, with the laser set to 635 nm, at Power 80 and PMT 70 setting, and a scan resolution of 10 um.
Description No additional information.
Data processing Data Processing Protocol
Calculation Method: Raw data were normalized and analyzed in GENESPRING software version 6.1.1 (Silicon Genetics, Redwood City, CA). GENESPRING generated an average value of the spot replicates of each miRNA. After data transformation (to convert any negative value to 0.01), normalization was performed by using a per-chip on median normalization and a normalization to specific samples used as common reference for miRNA expression.
