|
Source name |
HCC peritumor tissues
|
Organism |
Homo sapiens |
Characteristics |
patient diagnosis: hepatocellular carcinoma (HCC) subject id: 1329 gender: Male age: 63 tissue: liver tissue region: peritumor
|
Extracted molecule |
total RNA |
Extraction protocol |
Total RNA from HCC tumor and peritumor tissue samples were extracted using TransZol reagents. rRNAs were removed by a Ribo-Zero Magnetic kit, and linear RNA was digested by RNase R before construction of the RNA-seq libraries. RNA libraries were prepared for sequencing using standard Illumina protocols

Data processing |
The sequencing reads that meet any of the following criteria were removed: (1) containing adaptor sequence; (2) with >10% ambiguous bases (N) of total read length; (3) containing >20% low quality bases (base quality ≤ 20) of total read length Qualified reads were aligned to ribosomal rRNA sequences download from RNAcentral database to remove possible rRNA inference. The unmapped reads were aligned to UCSC human genome reference (GRCh37/hg) using TopHat2 All the reads that could not align to the genome were extracted to identify the potential back-spliced junction reads by TopHat-Fusion. The identified potential candidate reads that could be mapped to the same chromosome but in reverse order were further considered as the candidate back-spliced junction reads After removing any circular RNA with less than two unique back-spliced reads in one tissue sample, the expression levels for each circular RNA were calculated, according to reads Per Million mapped reads (RPM) using all the junction reads within the circular RNA region Genome_build: hg19 Supplementary_files_format_and_content: tab-delimited text files include RPM values for each Sample.
