ssc-miR-9: Ssc-mir-9 is a microRNA that has been identified in several studies and has been found to target host-encoded pre-miRNAs, including ssc-mir-21 [PMC4363316]. In pig samples, ssc-mir-9, along with ssc-mir-26a and ssc-mir-99a-5p, were found to be abundantly expressed [PMC7809845]. The accuracy of miRNA sequencing data was validated by qRT-PCR for five differentially expressed miRNAs, including ssc-mir-9 [PMC9778086]. In another study, ssc-mir-9 was found to be down-regulated along with several other miRNAs in a high feed efficiency group compared to a low feed efficiency group [PMC9778086]. The expression of ssc-mir-9 was also found to be inhibited by the YN15 strain and activated by the YN144 strain in relation to the expression of FN1, ITGβ1, and ITGα5 [PMC7820490]. Additionally, ssc-mir-9 was identified as one of the miRNAs that regulate pathogenicity-related signaling pathways [PMC7820490].
