Sample GSM4203157 Query DataSets for GSM4203157
Status Public on Feb 24, 2020
Title pregnant uterus miRNA rep 3
Sample type SRA
 
Source name uterus
Organism Equus caballus
Characteristics tissue: uterus
Stage: pregnant
Treatment protocol cyclic mares: no treatment, pregnant mares: inseminated and confirmed to be pregnant
Growth protocol Samples were collected from cycling or pregnant mares 13 days after ovulation
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from the UF and the YS fluid samples for miRNA analysis, using the miRNeasy Serum/Plasma kit (Qiagen), according to the manufacturers' instructions. For RNA extraction from the B and the E tissue samples, the RNeasy Mini Kit (Qiagen) was combined with the RNeasy MinElute Cleanup Kit (Qiagen) in order to extract both small RNAs and larger RNAs (>200 nt) separately from the same tissue sample for mRNA- and miRNA-Sequencing respectively.
MicroRNA sequencing libraries were constructed and size-selected with the TailorMix miRNA Sample Preparation Kit V2 (SeqMatic, Fremont, CA, USA) using 100 ng total RNA and amplified by 18 PCR cycles.

Data processing Adapter trimming and removal of reads shorter than 17 bp, having a quality score lower than 20 or containing any ambiguities, was done using cutadapt (v1.11).
Feature counting, identification of known miRNAs and prediction of putative novel miRNA were done using the miRPro pipeline.
MicroRNA data from miRBase (release 22) and the corresponding annotated horse genome (EquCab2.0) were used as a reference. All mammalian data in miRBase was used for the prediction of novel miRNA.
Genome_build: EquCab2.0
Supplementary_files_format_and_content: Comma separated count files. Fasta files of the predicted miRNAs.
