bta-mir-202: Bta-mir-202 is a microRNA that has been found to be significantly increased at 8 hours [PMC9260119]. It has been shown to prevent the apoptosis of LPS-induced bMECs [PMC9260119]. Bta-mir-202 is only expressed in the testis and ovary of cattle [PMC5053184]. It is one of the 13 differentially expressed miRNAs that regulate a total of 182 differentially expressed genes [PMC7911131]. In bovine growth and atresia follicles, bta-mir-202 is upregulated in large healthy follicles compared to small follicles and plays a functional role in follicular atresia [PMC10080932]. Bta-mir-202, along with other miRNAs, has differential expression patterns in stem-loop RT-qPCR results compared to RNA-Seq results [PMC4840452]. It is upregulated in large healthy follicles and targets signaling pathways involved in follicular cell proliferation and steroid generation [PMC8316591]. Bta-mir-202 is exclusively expressed in the gonads and may regulate the viability of mural follicles [PMC5736867]. In the bovine corpus luteum (CL), bta-mir-202 peaks during early CL development but decreases in subsequent CL classes, with low expression levels in regressing CL [PMC5736867]. The role of bta-mir-202 in the bovine CL is not fully understood but it may be involved in blocking cell proliferation, invasion, or apoptosis during early CL development [PMC5736867].
