| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was harvested using Rneasy mini plus kit (Qiagen) with DNAse treatment.
RNA libraries for RNA-seq were prepared using Illumina TruSeq stranded mRNA library construction Kit following manufacturer's protocols.

| Data processing |
Raw reads were trimmed for adapters, polyA read-through, and low-quality tails (quality <Q20) using BBDuk (version 37.02; sourceforge.net/projects/bbmap/).
Reads were subsequently aligned to the human reference genome (hg38) using STAR (version 2.7.3a; ref Dobin et al., 2013) with default parameters.
Raw gene counts were obtained using the featureCounts function of the Rsubread R package (version 2.0.1; ref Liao et al., 2014) and the Gencode gene annotation for hg38 genome.
Gene counts were normalized to counts per million mapped reads (cpm) using the edgeR package (version 3.28.1; ref Robinson et al., 2010); only genes with a CPM greater than 1 in at least 2 samples were further retained for differential analysis. Differential gene expression analysis was performed using the DESeq function of the DESeq2 package.
Assembly: hg38
Supplementary files format and content: Expression matrix of raw counts for each sample
