bta-miR-129: Bta-mir-129 is a bovine miRNA that has been studied in various contexts. In one study, it was among the miRNAs assessed in both murine and bovine samples [PMC9188571]. Another study found that bta-mir-129 was one of the miRNAs involved in the regulation of IGF-1 expression, along with other circRNAs and miRNAs [PMC9821774]. Specifically, bta-mir-129 and a circRNA called novel_circ_016821 were identified as the main regulatory factors [PMC9821774]. In a different study, bta-mir-129 was found to be increased at day 7 of the estrous cycle compared to day 3 [PMC4156418]. Additionally, it was up-regulated in pregnant cows but not detected across the estrous cycle [PMC7969882]. Finally, at parturition, bta-mir-129 was part of a group of miRNAs that showed time-dependent expression patterns, with some being overexpressed and others being downregulated [PMC9445238]. These findings highlight the involvement of bta-mir-129 in various biological processes and its potential as a biomarker or therapeutic target.
