title: Illumina HiScanSQ sequencing; miRNA sequencing data from patients with non-active gastritis, chronic active gastritis and precursor lesions of gastric cancer.
design: miRNA sequencing data from patients with non-active gastritis, chronic active gastritis and precursor lesions of gastric cancer.
library_construction_protocol: Two corpus and two antrum biopsy specimens were collected from each individual and conserved in RNAlater. Total RNA was isolated from two pooled biopsies using mirVana miRNA Isolation Kit (Ambion). Libraries were constructed using TruSeq-SmallRNA Sample Prep Kit (Illumina) following the standard protocol.
