ssc-mir-215: ssc-mir-215 is a microRNA that has been found to be involved in various biological processes in pigs. It has been shown to competitively bind to other microRNAs such as ssc-miR-490-5p, ssc-miR-216, ssc-miR-874, and ssc-miR-184 [PMC6458635]. In different studies, ssc-mir-215 has been found to be both upregulated and downregulated in various tissues and conditions. For example, it was upregulated in infected intestinal tissues [PMC5326932] and in the lungs of Tongcheng pigs [PMC5381705]. On the other hand, it was downregulated in infected intestine samples [PMC5326932] and in Landraces' lungs [PMC5381705]. The expression levels of ssc-mir-215 were also found to be significantly different between different groups based on RT-qPCR results [PMC3832476]. It has been suggested that ssc-mir-215 may play a role in regulating epithelial cell differentiation [PMC5326932]. Additionally, it has been predicted to bind with multiple target genes involved in various biological processes such as NCEH1, CHRNA6, RORC, TPPP3, HSPB6, FRAS1, and TNNI1 [PMC7264268]. Overall, the expression of ssc-mir-215 appears to be influenced by different factors and may have diverse functions depending on the specific context.
