Sample GSM785440 Query DataSets for GSM785440
Status Public on Sep 01, 2013
Title Testicular_cancer_06_N_miRNA
Sample type SRA
 
Source name testicular, normal
Organism Homo sapiens
Characteristics cell type: testicular germ
cancer or normal: normal
Extracted molecule total RNA
Extraction protocol 5μg of total RNA extracted from each sample was ligated with both 5’adapter and 3’adapter for reverse transcription by Superscript II, and the reverse transcribed products were amplified subsequently. After collection of ~92bp DNA band on the 6% PAGE gels, PCR products were ethanol precipitated and purified by Spin-X filter columns. Finally, miRNA libraries were sequenced on the Illumina Cluster Station and Genome Analyzer Ⅱ sequence system following the manufacturer’s protocol.
 
Library strategy miRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina Genome Analyzer II
 
Description T27N
Data processing Low quality reads were trimmed and adapter sequences were accurately clipped with the aid of a dynamic programming algorithm before subsequent statistical analysis. After elimination of the duplicated reads, the remaining reads no shorter than 18nt were mapped to human reference genome (hg18) using SOAP V2.0. To remove tags originating from protein coding genes, repeat sequences, rRNA, tRNA, snRNA, and snoRNA, we also mapped the short read tags to UCSC RefGene, RepeatMasker and NCBI Refseq, as well as our in-house ncRNA annotation data sets compiled from the NCBI Genbank database (http://www.ncbi.nih.gov). The similar pipeline used for DGE mRNA differential expression analysis was also applied to miRNAs study. We investigated the biological relevance of miRNA through their regulation of target genes. First, pearson correlation analysis was perform to identify potential targets. Meanwhile, another target gene set was generated according to the intersect result of any two predicted algorithms of DIANA-microT 3.0, TargetScan 5.1, and PicTar. Next, those potential targets defined by the predicted target gene set above were subjected to further analysis.
