In this study, we comprehensively analyzed and identified the histological parameters of hair follicles, as well as the miRNAs, target genes, pathways, and Gene Ontology terms related to wool fineness regulation and wool growth and development using HE staining and RNA-Seqs methods. Both coarse (group C, mean fiber diameter (MFD) = 22.26 ± 0.69 μm, <em>n</em> = 6) and fine (group F, MFD = 16.91 ± 0.29 μm, n = 6) of Gansu alpine fine-wool sheep with different wool fineness were used in this study. The results showed that the primary follicle diameter and secondary wool fiber diameter in group C were significantly higher than those in group F (<em>P</em> < 0.05). And the number of primary and secondary hair follicles in group C was significantly lower than that in group F (<em>P</em> < 0.05). Furthermore, a total of 67 DE miRNAs and 290 potential DE miRNAs target genes were screened in the skin tissues of sheep from groups F and C, and some potential target genes related to wool fineness regulation were screened, such as <em>CDH2</em>, <em>KRT82</em>, <em>FOXN1</em>, <em>LOC101106296</em>, <em>KRT20</em>, <em>MCOLN3</em>, <em>KRT71</em>, and <em>TERT</em>.

The proliferation and differentiation process of sheep myoblasts directly affects the growth and development of their muscles, thereby affecting the yield of mutton. Myomesin 3 (<em>Myom3</em>), as a functional gene related to muscle growth, currently lacks research on its function in myoblasts. This study aims to investigate the effect of the <em>Myom3</em> gene on the proliferation and differentiation of sheep myoblasts and its potential molecular mechanisms. The results showed that inhibitor of <em>Myom3</em> in the proliferation phase of myoblasts resulted in significant downregulation of the proliferation marker gene paired box 7 (<em>Pax7)</em> and myogenic regulatory factors (<em>MRFs</em>; <em>Myf5</em>, <em>Myod1</em>, <em>Myog</em>, <em>P</em> < 0.01), a significant decrease in the EdU-positive cell rate (<em>P</em> < 0.05), and a significant increase in the cell apoptosis rate (<em>P</em> < 0.01), which inhibited the proliferation of myoblasts and promoted their apoptosis. During the differentiation phase of myoblasts, the inhibitor of <em>Myom3</em> resulted in significant downregulation of the <em>Pax7</em> gene, upregulation of <em>MRFs</em> (<em>Myod1</em>, <em>Myog</em>, <em>P</em> < 0.05), and a significant increase in fusion index (<em>P</em> < 0.05), promoting the differentiation of myoblasts. Further transcriptome sequencing revealed that differentially expressed genes in the <em>Myom3</em> interference group were mainly enriched in the MAPK signaling pathway, TNF signaling pathway, and IL-17 signaling pathway. In summary, the inhibitor of <em>Myom3</em> inhibits myoblast proliferation and promotes myoblast differentiation.
