bta-mir-184: Bta-mir-184 is a miRNA that has been found to be differentially expressed in various studies. It has been detected in bovine mammary epithelial cells challenged with heat-inactivated E. coli and S. aureus bacteria [PMC4585011]. It is also expressed during E. coli infection, while other miRNAs, such as bta-mir-2339, miR-499, miR-23a, and miR-99b, are specific to S. aureus infection [PMC9539446]. Bta-mir-184 has been detected in both control and S. aureus infected groups [PMC5821052]. It has also been found to have different binding capacity with haplotypes in NY cattle [PMC7824473]. Bta-mir-184 is upregulated in EVs from good-quality embryos and may block cell functions required for normal embryo development [PMC7727673]. It is also associated with bovine embryo competence [PMC7727673]. Bta-mir-184 expression levels have been found to be increased during yak testicular development and spermatogenesis [PMC9940382]. In infected compartments, bta-mir-184 expression is upregulated compared to the control group [PMC4840452]. Bta-mir-184 has also been detected in the culture medium of bovine embryos and is related to embryo competence [PMC5617439]. In addition, bta-mir-184 is expressed specifically in rumen and gut tissues of cattle [PMC6371894]. Overall, bta-mir-184 plays a significant role in various biological processes related to infection response, embryonic development, testicular development, and gut tissue specificity.
