| Title |
22Rv1, Liver metastase drived, rep3 |
| Sample type |
SRA |
| |
|
| Source name |
Cell line
|
| Organism |
Homo sapiens |
| Characteristics |
tissue: Cell line
cell line: 22Rv1
cell type: Prostate cancer cell line
genotype: Liver metastase drived
|
| Growth protocol |
The medium for this cell lines is RPMI-1640 Medium supplumented with 10% fetal bovine serum.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted from each tissue by using Qiagen's ‘RNeasy’ RNA extraction kit (Qiagen).
RNA-sequencing was performed by GENEWIZ (South Plainfield, NJ, USA). RNA quantity and integrity were determined using the Qubit® Fluorometer and the Fragment Analyzer system with the PROSize 3.0 software (Agilent Technologies, Palo Alto, California, USA). The RQN were ranging from 8.8 to 10 for all samples, which was considered sufficient. Illumina TruSEQ RNA library prep and sequencing reagents were used following the manufacturer’s recommendations using polyA-selected transcripts (Illumina, San Diego, CA, USA). The samples were sequenced on the Illumina NovaSeq platform (2 x 150 bp, single index) and generated ~20 million paired-end reads for each sample.

Assembly: GRCh38
Supplementary files format and content: Sequence reads were trimmed to remove possible adapter sequences and nucleotides with poor quality using Trimmomatic v.0.36. The trimmed reads were mapped to the Homo sapiens GRCh38 reference genome available on ENSEMBL using the STAR aligner v.2.5.2b. The STAR aligner is a splice aligner that detects splice junctions and incorporates them to help align the entire read sequences. BAM files were generated as a result of this step. Below are the statistics of mapping the reads to the reference genome.
Supplementary files format and content: Unique gene hit counts were calculated by using featureCounts from the Subread package v.1.5.2. The hit counts were summarized and reported using the gene_id feature in the annotation file. Only unique reads that fell within exon regions were counted. If a strand-specific library preparation was performed, the reads were strand-specifically counted.
