bta-mir-326: Bta-mir-326 is a downregulated microRNA (miRNA) in bovine species that exhibits high betweenness centrality in a network analysis, indicating its potential role as a key regulator in the network of downregulated miRNAs when comparing day 28 and 63 postpartum [PMC9445238]. This miRNA is implicated in the regulation of spermatogenesis, as evidenced by its targeting of the prolactin receptor (PRLR) gene, which significantly affects the proliferation of rat Sertoli cells [PMC9940382]. Bta-mir-326 is also involved in yak testis development and spermatogenesis through its targeting of multiple members of the TGF-β signaling pathway, including BMP2, TGFB2, SMAD6, GDF6, and TGFBR2 [PMC9940382]. It is associated with the Wnt signaling pathway, but the specific number of genes it targets within this pathway is not detailed [PMC9940382]. Additionally, bta-mir-326 is identified as one of the most multifunctional miRNAs influencing genes within the GnRH signaling pathway [PMC9940382], and it plays a role in controlling target genes across multiple pathways such as TGF–β, GnRH, PI3K–Akt, MAPK, Wnt, and AMPK pathways [PMC9940382], highlighting its broad regulatory potential across various biological processes related to reproductive development.
