dre-mir-22a: Dre-mir-22a is a miRNA that has been selected for expression profiling in zebrafish early development due to its known or potential roles in this process [PMC3932949]. It is part of the top 5 most abundant miRNA families expressed at each stage of zebrafish development [PMC3932949]. The expression levels of dre-mir-22a, along with three other known miRNAs, were determined using quantitative real-time PCR assays [PMC3932949]. The expression patterns of dre-mir-22a in zebrafish early development were found to be consistent with the studies conducted in the early development of chicken [PMC3932949]. Dre-mir-22a was highly expressed from the 1-cell stage to 24hpf in zebrafish embryos [PMC3932949]. The sequence for dre-mir-22a-MO, a morpholino oligonucleotide used for knockdown experiments, was provided [PMC8984383]. Additionally, a custom-designed TaqMan MicroRNA assay for dre-mir-22a was used for further analysis [PMC8984383]. Overall, dre-mir-22a is an important miRNA that plays a role in zebrafish early development and its expression patterns have been characterized using various experimental techniques.
