ssc-mir-200b: Ssc-mir-200b is a functional miRNA that has been identified in various studies [PMC9603960] [PMC8122421] [PMC7685987] [PMC9961432]. It has been shown to target the porcine spermatogenesis-associated serine-rich 2-like (SPATS2L) gene, which significantly affects litter size [PMC7685987] [PMC9961432]. Ssc-mir-200b is one of the most abundant miRNAs found in boar seminal plasma extracellular vesicles (SP-EVs) [PMC7685987]. It is also among the top 10 most abundant miRNAs in boar SP-EVs, comprising a significant proportion of total miRNA reads [PMC7685987]. Ssc-mir-200b, along with other miRNAs such as ssc-miR-10b and ssc-miR-10a-5p, is found in both groups of differentially expressed miRNAs and among the topmost abundant miRNAs in sperm datasets, suggesting its critical regulatory role in various physiological processes in sperm [PMC9961432]. Overall, ssc-mir-200b has been identified as an important functional miRNA that may play a role in spermatogenesis and influence litter size.
