| Sample type |
SRA |
| |
|
| Source name |
Right ventricle
|
| Organism |
Homo sapiens |
| Characteristics |
tissue: Right ventricle
Sex: F
primary disease_characterization: Compensated RV
secondary group_characterization: Decompensated-1 RV
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Human RV tissues were manually dissected in cardiac biopsy or autopsy, according to the previously described protocol ( doi: 10.1161/CIRCULATIONAHA.120.047626 ), and Total RNA from each batch of RV samples were isolated separately using the RNeasy Mini Kit (Qiagen, Germantown, MA, USA) and snap-frozen. Purification of total RNA was performed as described in the RNeasy handbook, using DNase I digestion (RNase-Free DNase Set, Qiagen).
Following the RNA integrity measurement, approximately 10 ng of total RNA were used as starting material for library preparation using the SMARTer® Stranded Total RNA-seq Kit - Pico Input Mammalian, following manufacturers’ protocols

| Data processing |
Raw fastqs were assessed for quality, adapter content, and duplication rates using FastQC. Trimmomatic version 0.39 was employed to trim reads following a quality drop (below a mean of Q15) in a window of five nucleotides

The number of reads that aligned to genes was counted using featureCounts version 1.6.5 from the Subread package. Only reads mapping at least partially inside exons were aggregated and counted per gene. Reads aligning to multiple regions or genes were excluded. -t exon -g gene_id -s 2; multi-mapping: no; duplicates: no
Raw count values for each organism were normalized separately using DESeq2 version 1.30.0, then transformed into regularized logarithm values for further analysis. Because we had two different batches of human samples, we performed a batch effect correction on this data using the sva package. The normalized and batch-corrected data were the basis of downstream analysis.
