ssc-mir-34a: Ssc-mir-34a is an endogenous control that has been confirmed to be stably expressed in peripheral blood mononuclear cells (PBMC) [PMC5085634]. It has been predicted to have target sites in SLA-1 and HSPA1A, as well as disrupted target sites in RNF5 and SLA-1 [PMC3490867]. In a study on the expression profile of novel miRNAs in pig tissues, ssc-mir-34a was found to be mainly expressed in the lungs [PMC3427155]. It has also been identified as one of the miRNAs that potentially binds to circ_2141, along with ssc-miR-133a-5p, ssc-miR-138, and ssc-miR-7137-3p [PMC9219244]. Furthermore, a down-regulated circRNA called "circ 11:4104218-4118265" was found to interact with FSTL4 via ssc-mir-34a [PMC7827264]. Ssc-mir-34a is also listed as one of the miRBase identifiers for various species including humans (hsa-miR-34a), mice (mmu-miR-34a), rats (rno-miR-34a), and pigs (ssc-mir-34a) [PMC5085156]. The primers for amplifying miRNAs include a specific forward primer for ssc-mir 34-a [PMC4908419]. In summary, ssc-mir 34-a is an endogenous control that is stably expressed in PBMCs and has predicted target sites in various genes. It is mainly expressed in the lungs and potentially interacts with circ_2141.
