eca-mir-370: Eca-mir-370 is an upregulated microRNA (miRNA) in undescended testes (UDTs) compared to descended testes (DTs) in donkeys [PMC7070967]. It is involved in controlling muscle fiber composition by targeting genes mainly involved in actin binding and the glycolysis/gluconeogenesis pathways [PMC9498731]. The expression of eca-mir-370 was found to be upregulated in UDTs compared to DTs, consistent with the sequencing method [PMC7070967]. Several genes, including TPM2, TNNC1, TNNI1, MYH14, and ACADS, were predicted to be targets of eca-mir-370 and were more highly expressed in slow muscle fibers [PMC9498731]. Additionally, TNNC1, TPM2, TNNI1, and MYH14 were targets of the upregulated eca-mir-370 and enriched in PM (posterior muscle) [PMC9498731]. Eca-miR-193a-5p and eca-mir-370 were identified as microRNAs involved in actin binding and the glycolysis/gluconeogenesis pathways that potentially coregulate muscle fiber types [PMC9498731]. Eca-miR-199b-5p, eca-mir-370, and eca-miR-758 were upregulated miRNAs in BF (biceps femoris), while eca-miR-196b, eca-miR196a,e miR192,e miR6153p,e miR4993p,e miR128,and emiRNA1935p were downregulated miRNAs [PMC9498731]. Eca-miRNA1935p ,eca-MIR1379,and emiRNA370 showed large numbers of target genes in the networks [PMC9498731]. However, further studies are needed to validate these findings and understand the complex regulatory mechanisms involved [PMC9498731].
