Identification of miRNA in bovine colostrum and mature milk and proposal of potential biomarkers for quality control of raw milk and dairy foods. miR-26a, miR-26b, miR-200c, miR-21, miR-30d, miR-99a, and miR-148a could potentially be used as biomarkers for quality control in raw milk and dairy products (Chen et al., 2010)
Identification and comparison of exosomal miRNA composition in human, caprine, and bovine colostrum and mature milk. miR-30a-5p, miR-22-3p, and miR-26a are highly conserved in colostrum and mature milk of three mammals, including humans, caprine, and bovines. (Yun et al., 2021)
Identification and comparing miRNAs in bovine colostrum and mature milk using microarray and qPCR analysis. miR-15b, miR-27b, miR-34a, miR-106b, miR-130a, miR-155, and miR-223 are related to immunity or development and are more expressed in colostrum than mature milk. (Izumi et al., 2012)
Identification of miRNA and mRNA of bovine milk exosomes and confirmation of uptake into human macrophages. Among the analyzed miRNAs, 14 bovine-specific miRNAs (miR-2478, miR-2412, miR-2305, miR-2881, miR-2328*, miR-2888, miR-2304, miR-2391, miR-2892, miR-2887, miR-2316, miR-2374, miR-2291, and miR-2284l) were recognized. (Izumi et al., 2015)
Comparison of miRNA distribution in milk EVs according to different ultracentrifugation. The top 4 miRNAs of P12K and P35K were bta-let7a, bta-miR-30a, bta-miR-21, and bta-let7b, and bta-mir-10a and bta-mir-10b were most expressed in P70K and P100K, respectively. (Benmoussa et al., 2020)
Identification and characterization of milk exosomal miRNAs in cows with mastitis. Eighteen miRNAs, including four novel miRNAs (bta-let-7b, bta-miR-103, bta-miR-142-3p, bta-miR-142-5p, bta-miR-1468, bta-miR-146a, bta-miR-146b, bta-miR-147, bta-miR-221, bta-miR-223, bta-miR-2284w, bta-miR-2285b, bta-miR-23a, bta-miR-423-5p, etc.), had differential expression, and miR-223 and miR-142-5p were considered for use as potential biomarkers for the diagnosis of mastitis. (Cai et al., 2018)
Profiling of expression of milk exosomal miRNA in cows infected with Staphylococcus aureus. According to the presence or absence of infection, 14 miRNAs (bta-miR-142-5p, bta-miR-296-5p, bta-miR-223, bta-miR-1246, bta-miR-183, bta-miR-502b, bta-miR-378b, bta-miR-2285 g-3p, bta-miR-99a-5p, bta-miR-181b, bta-miR-101, bta-miR-10a, bta-miR-99b, and bta-miR-2419-5p) were expressed differently, in particular bta-miR-142-5p, and -223 were suggested as potential biomarkers for detection of infection. (Sun et al., 2015)
Confirmation of changes in the expression of bovine milk EVs-miRNA as a result of changes in feed. When fed on a nonforage fiber sources diet, 4 miRNAs (bta-miR-29c, bta-miR-760-3p, bta-miR-383, and bta-miR-11973) among milk EVs miRNAs were upregulated, and 5 miRNAs (bta -miR-328, bta-miR-10167-3p, bta-miR-103, bta-miR-885, and bta-miR-302d) were downregulated.
