dre-miR-21: Dre-mir-21 is a type of miRNA that has been studied in various contexts. LNA in situ hybridization was used to detect dre-mir-21 expression in kidney cryosections [PMC4650918]. Dre-mir-21 was found to be highly expressed in muscle miRNAs, accounting for 21% of the total [PMC2684549]. In a study using zebrafish larvae, dre-mir-21 was one of the upregulated miRNAs after TnP treatment [PMC8268205]. The mature sequence region of dre-mir-30e-2 was replaced with the mature sequence of dre-mir-21 in a specific vector [PMC8583575]. In another study, the expression levels of dre-mir-21 were found to be elevated in the liver of zebrafish injected with MCs [PMC5308255]. Dre-mir-21, along with other highly expressed miRNAs like dre-miR-143, played a role in regulating fish activities under hypoxia stress [PMC8696637]. Dre-mir-21 is part of the miR-21 family, which includes homologous miRNAs from different species such as Gallus gallus and Homo sapiens [PMC3923817].
