| Title |
Severe TBI #1 |
| Sample type |
SRA |
| |
|
| Source name |
Tail-vein plasma
|
| Organism |
Rattus norvegicus |
| Characteristics |
strain: Sprague-Dawley
age: Adult
group: Severe TBI
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Whole blood was drawn from the lateral tail-vein under isoflurane anesthesia, into Microtainer K2 EDTA-tubes. The blood samples were thoroughly mixed with EDTA and placed on ice. Centrifugation was performed immediately at 1300g for 10 min (+4°C) to obtain plasma. RNA was isolated from 200 µL plasma using the miRNeasy serum/plasma kit.
Small RNA libraries were prepared with QIASeq miRNA library kit for Illumina NGS systems.
Small RNA-Seq. Single-end sequencing of 75 bp reads performed at a depth of 12M, with one sample/lane in the Illumina NextSeq 550.

| Data processing |
Raw sequencing data was analysed with the Qiagen Geneglobe Data analysis center (DAC), a freely available web resource to analyze data from Qiagen’s QIASeq NGS library kits (https://geneglobe.qiagen.com/in/analyze/).
Primary quantification of read counts was performed in the DAC, which involved the following steps: (i) trimming of the 3’-adapter and low-quality bases using cutadapt, (ii) identifying the insert sequences and unique molecular indices (UMIs) (reads with <16 bp insert sequences or < 10 bp UMI sequences were discarded), (iii) alignment of the processed reads to the rat reference genome RGSC Rnor_6.0 with a sequential alignment strategy using bowtie (perfect match to miRBase mature, miRBase hairpin, noncoding RNA, mRNA and other RNA, and ultimately a second mapping to miRBase mature, where up to two mismatches are tolerated). Annotation of the miRNAs in the DAC portal was performed with miRBase v21.
