bta-mir-30b: Bta-mir-30b is a microRNA that has been reported to be involved in various signaling pathways, including insulin, lipid, immune system, oxidative stress response, and muscle development [PMC9039951]. It is also associated with feed efficiency in cattle [PMC9039951]. Integrative network analysis has shown that bta-mir-30b can potentially interact with several genes related to oxidative stress, metabolism of xenobiotics, fatty acid metabolism, and muscle development [PMC6244318]. It has been identified as a hub miRNA that may regulate biological pathways related to feed efficiency [PMC6244318]. In some cases, the miRNA* form of bta-mir-30b was found to be more abundant than the corresponding miRNA form [PMC2713767]. ZMYND10 is a hub-hub gene that is potentially targeted by bta-mir-30b [PMC8433134]. In the context of bovine endometritis, bta-mir-30b has been identified as one of the potential miRNAs involved in the progression of this infection and could serve as a biomarker and therapeutic target [PMC8433134]. Additionally, bta-mir-30b has been found to be down-regulated and has binding sites on mRNA of various genes involved in different biological processes such as muscle contraction (CNN1), chemotaxis (CXCR7), and growth regulation (IGFBP3) [PMC5003961].
