miRNA expression and distribution.

<p>(A) miRNA numbers of two pig breeds; YB and YC indicate Bama minipigs and Landrace pigs, respectively. (B) Scatter plots of miRNA expression; <i>r</i> represents correlation between Bama minipigs and Landrace pigs and the solid dots represent significantly changed miRNAs. (C) The average expression levels of miRNAs and their corresponding proportion in the anterior pituitary. (D) The miRNA numbers of the two pig breeds at different expression levels. (E) Cluster analysis of differentially expressed miRNAs between YB and YC. YB and YC indicate Bama minipigs and Landrace pigs, respectively.
