Hypothalamic miRNA Expression in Sunite Sheep Under Three Photoperiod Conditions

57, 47, and 12 differentially expressed miRNAs were identified between short, long, and transitional photoperiods in Sunite sheep. The dataset, created by Yajing Shao and last updated in April 2026, contains miRNA-sequencing results from three biological replicates per condition. It includes co-expression networks and functional annotations linking miRNAs to reproductive signaling pathways.

Use Cases

• Identify key miRNAs associated with photoperiod changes based on differential expression analysis.
• Analyze gene co-expression networks based on predicted miRNA-mRNA interactions.
• Investigate enrichment of reproductive pathways like GnRH and prolactin signaling based on functional annotation.
• Validate candidate miRNAs for seasonal estrus regulation based on the provided expression profiles.

Strengths

• Data includes three biological replicates per experimental group, suggesting biological validation.
• Analysis identified specific differentially expressed miRNA counts (57, 47, 12) between defined photoperiod comparisons.
• Functional annotation links target genes to concrete KEGG pathways relevant to reproduction.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset is very small (14.3 KB), indicating limited scope, likely summary results rather than raw sequencing data.
