bta-mir-155: Bta-mir-155 is a conserved miRNA that has been studied in various contexts. In a study comparing time points in humans, hsa-miR-155-5p, which is homologous to bta-mir-155, showed significant contrasts [PMC9825267]. Another study comparing grazing and corn silage groups found that bta-mir-155 was more abundant in the grazing farms [PMC9569736]. Bta-mir-155 has also been investigated in relation to bovine mastitis. It was found to be one of the miRNAs integrated with differentially expressed genes (DEGs) and other mastitis-related miRNAs [PMC8511192]. Specifically, bta-mir-155 was identified along with bta-miR-146a, bta-miR-21-5p, bta-miR-31, and bta-miR16a [PMC8511192]. In granulosa cells of SF (superovulated follicles), the expression level of bta-mir-155 was significantly upregulated at day 7 compared to day 3 [PMC4156418]. Bta-mir-155 has also been implicated in the regulation of IL18 along with other factors such as bta-miR16a and HNF3 transcription factor [PMC8511192]. These studies highlight the involvement of bta-mir-155 in various biological processes and its potential as a biomarker or therapeutic target.
