Sample GSM6619965 Query DataSets for GSM6619965
Status Public on Dec 06, 2023
Title Non-Responder, A11_385T
Sample type SRA
 
Source name tumor
Organism Homo sapiens
Characteristics tissue: tumor
disease state: HCC
group: Nonresponder
Extracted molecule total RNA
Extraction protocol Flash frozen on dry ice, and RNA was harvested using Trizol reagent.
RNA libraries were prepared for sequencing using standard Illumina protocols
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Data processing Original data file from Illumina is transformed into sequenced reads (raw data, FASTQ formate files) by CASAVA base recognition.
Raw data is filtered by removal of reads with adaptor contamination,reads when uncertain nucleotides constitute more than 10 percent of either read (N > 10%),reads when low quality nucleotides (Base Quality less than 20) constitute more than 50 percent of the read. The Qscore (Quality value) of over 50% bases of these read is <= 5.
Sequencing is mapped to Homo_sapiens_hg19 by STAR software. The alignment by STAR performs precise and effective in positioning junction reads for RNA sequencing data analysis.
FPKM (short for the expected number of Fragments Per Kilobase of transcript sequence per Millions base pairs sequenced) is the most common method of estimating gene expression levels, which takes the effects into consideration of both sequencing depth and gene length on counting of fragments (Mortazavi et al. 2008).
For the samples with biological replicates, differential expression analysis of two conditions/groups was performed using the Limma R package.
Assembly: Homo_sapiens_hg19
Supplementary files format and content: A txt file of gene expression level (FPKM value) of all samples.
