bta-mir-19b: Bta-mir-19b is a microRNA that has been identified in various studies and is associated with different biological functions and pathways. It has been found to be abundantly expressed in LPS- and CpG-treated samples, as well as in control samples [PMC7903524, PMC4892552]. Bta-mir-19b has also been reported to be associated with Wnt signals and the MAPK pathway [PMC9445238]. In some studies, the expression of bta-mir-19b was found to be differentially expressed after MAP infection [PMC6600136]. Additionally, bta-mir-19b has putative target sites in the 3'UTR region of genes such as BEDNRB, IGFBP3, POSTN, and DHRS3 [PMC5003961]. It has also been identified as one of the miRNAs that are differentially expressed between moderate and high fertility groups [PMC9113469]. Furthermore, bta-mir-19b was found to be upregulated in non-pregnant cows compared to pregnant cows [PMC7458322]. In relation to disease conditions, bta-mir-19b has been associated with human tuberculosis and inflammatory bowel disease [PMC5070780]. It was also found to target genes such as HIC1, TBC1D8, IMPDH1, and ZBTB4 in different groups [PMC5070780]. Overall, bta-mir-19b is a versatile microRNA that plays a role in various biological processes and disease conditions.
