57 differentially expressed miRNAs were identified between short and long photoperiod conditions in Sunite sheep hypothalami. This dataset likely contains miRNA expression patterns from three photoperiod groups—short, long, and transition—with three biological replicates per group, analyzed via miRNA-sequencing. The data was authored by Yajing Shao and last updated on April 21, 2026.
Use Cases
- Identify differentially expressed miRNAs based on photoperiod-induced changes mentioned in the description
- Construct co-expression networks of miRNAs and target genes based on interaction analysis results
- Perform functional annotation to enrich target genes in KEGG pathways like GnRH signaling
- Validate candidate miRNAs such as oar-miR-370-5p for their role in seasonal estrus
Strengths
- Includes data from three distinct photoperiod conditions with three biological replicates per group
- Lists specific counts of differentially expressed miRNAs (57, 47, 12) between pairwise comparisons
- Identifies key miRNAs (oar-miR-370-5p, oar-miR-10b, oar-miR-3957-3p) with high numbers of predicted target mRNAs
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- The dataset is 11.9 KB, indicating a very limited scope of data
