title: GSM9135410: D1, On admission; Homo sapiens; RNA-Seq
library_construction_protocol: Using the PAXgene Blood RNA Kit (BD, USA), the total RNAs were extracted from samples of the rise distress group (Class 4) and decline distress group (Class 1) divided by LCGM following the manufacturer's instructions. A Nanodrop ND-1000 (Thermo Fisher, USA) was applied to measure the concentration and quality of total RNAs. The sequencing library was built using around 1–2 μg of total RNAs per sample. RNA sequencing services were provided by CloudSeq Inc. (Shanghai, China). Trizol (Invitrogen, USA) was utilized to extract Total RNA, and rRNA was removed via the GenSeq® rRNA Removal Kit (GenSeq, Inc., Shanghai, China). Directional RNA libraries were built via the GenSeq® Directional RNA Library Prep Kit. RNA was fragmented to ~300 nt in length. Reverse transcriptase and random hexamers were utilized to synthesize the first-strand cDNA. Moreover, the dUTP Mix was applied to synthesize the second-strand cDNA. The double-stranded cDNA fragments underwent end repair, adapter ligation, and dA-tailing. The cDNA, ligated with adapters, was PCR-amplified and purified to generate the final sequencing libraries. Furthermore, the libraries were sequenced in paired-end 150 bp mode.
