ssc-mir-30d: Ssc-mir-30d is a type of microRNA that is expressed at higher levels during the prenatal stage compared to the neonatal stage, and its expression pattern during muscle development reflects its relationship with myogenesis [PMC4423774]. It is one of the nine differentially expressed miRNAs that were validated through RT-qPCR [PMC4423774]. Ssc-mir-30d is one of the most abundant miRNAs at E90, along with ssc-miR-206 and ssc-miR-1 [PMC4423774]. It is also among the most abundant miRNAs in different samples, such as in LPS-treated and control groups [PMC7903524]. Ssc-mir-30d has been found to be up-regulated during YN144 infection and down-regulated during YN15 infection [PMC7820490]. It has been shown to regulate pathogenicity-related signaling pathways, including NF-κB and JAK-STAT pathways [PMC7820490]. In SLN, ssc-mir-30d was down-regulated at 7 dpi, coinciding with the detection of cytokines and immune mediators, as well as leucopenia and hemorrhages in infected animals [PMC5646143]. A SNP located in the precursor 3' stem of ssc-mir-30d has been associated with arachidic acid content [PMC8097994]. Ssc-mir-30d is expressed abundantly in skeletal muscles but is not classified as a myomiR [PMC3528764].
