Abundance and differential expression of the highly abundant caprine miRNAs in the mammary gland.

P and P-NE represent the actual sequencing count and normalized expression level of miRNAs in the small RNA library generated from the mammary gland during peak lactation, respectively.
D and D-NE represent the actual sequencing count and normalized expression level of miRNAs in the small RNA library generated from the mammary gland during the dry period, respectively.
Fold-change [log2 (P-NE/D-NE)] indicates the fold change of the miRNAs in a pair of samples.
The P-value reflects the significance of the miRNA differential between the samples. A smaller P-value indicates a more significant difference in the miRNA level between samples.
A sig-label of ** indicates a fold-change (log2)>1 or (log2)<-1 and a P-value<0.01.
