摘要：

The periodic regrowth of rabbit fur is economically important. Here, we aimed to characterise the histological traits and microRNA (miRNA) expression profiles in the skin tissue of Wan Strain Angora rabbits at different weeks after plucking. Haematoxylin-eosin staining showed that hair follicles were in the telogen phase in the first week, while they were in the anagen phase from the fourth to twenty-fourth weeks. In addition, two small RNA libraries derived from skin samples of Wan Strain Angora rabbits at telogen and anagen stages yielded over 24 million high-quality reads. Specifically, 185 miRNAs were differentially expressed between the telogen and anagen phases. The function of the differentially expressed miRNAs was explored by comparing them with known mammalian miRNAs and by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis of their predicted targets. Five new functional miRNAs were validated using quantitative real-time PCR. Moreover, the fibroblast growth factor 5 (FGF5) gene was verified to be a target of conservative_NC_013672.1_9290 and conservative_NC_013675.1_10734. We investigated differential miRNA profiles between the telogen and anagen phases of the hair cycle and our findings provide a basis for future studies focusing on the mechanisms of miRNA-mediated regulation of rabbit hair follicle cycling.
