ssc-miR-29b: ssc-mir-29b is a microRNA that has been identified in various studies and has been found to play a role in different biological processes. In the context of IAV infection in pigs, ssc-mir-29b was found to be modestly up-regulated on day 1 and 3 after challenge, suggesting its involvement in the antiviral response [PMC5909910]. It was also found to be up-regulated in sexually mature HZ boars and was associated with testicular development and spermatogenesis [PMC9622794]. Additionally, ssc-mir-29b was identified as one of the miRNAs that may regulate precocious sexual maturation traits in HZ boars [PMC9622794]. In another study, ssc-mir-29b was found to be upregulated at 2W compared with BW [PMC8367414]. It has also been implicated in the regulation of signaling pathways such as NF-κB and JAK-STAT [PMC7820490]. Furthermore, ssc-mir-29b expression was found to be differentially regulated during infection with different strains of IAV [PMC7820490]. The size of ssc-mir-29b has also been compared to miRBase entries, showing some differences [PMC3026822]. Overall, these studies highlight the diverse roles and regulation of ssc-mir-29b in various biological processes.
