“…miR-430 has conserved zygotic expression in another teleost fish, medaka (Tani et al, 2010), and has sequence similarity to several other embryonic miRNAs, including miR-295 in mouse; miR-302, miR-327 and miR-516-520 in human (Chen et al, 2005; Giraldez, 2010); and miR-427 in Xenopus (Lund et al, 2009). miR-427 has similar expression dynamics to miR-430 in the early Xenopus embryo, and was likewise shown to mediate maternal clearance activity (Lund et al, 2009), while miR-302 was found to be activated by Pou5f1 and Sox2 in ES cells (Card et al, 2008).…”

Embryogenesis depends on a highly coordinated cascade of genetically encoded events. In animals, maternal factors contributed by the egg cytoplasm initially control development, while the zygotic nuclear genome is quiescent. Subsequently, the genome is activated, embryonic gene products are mobilized and maternal factors are cleared. This transfer of developmental control is called the maternal-to-zygotic transition (MZT). In this review, we discuss recent advances toward understanding the scope, timing and mechanisms that underlie zygotic genome activation at the MZT in animals. We describe high-throughput techniques to measure the embryonic transcriptome and explore how regulation of the cell cycle, chromatin and transcription factors together elicits specific patterns of embryonic gene expression. Finally, we discuss the interplay between zygotic transcription and maternal clearance, and show how these two activities combine to reprogram two terminally differentiated gametes into a totipotent embryo.

“…Maternal mRNA stability, translation, and localization are the three features that determine control of early embryogenesis. miRNA expression profiling experiments have shown the probable role of miRNA in destabilization of maternal transcripts (Wienholds et al 2005; Tani et al 2010; Bizuayehu et al 2012a). mRNA degradation pathway through the miRNA mediation occurs after the MZT (Barckmann and Simonelig 2013).…”

MicroRNAs (miRNAs) are transcriptional and posttranscriptional regulators involved in nearly all known biological processes in distant eukaryotic clades. Their discovery and functional characterization have broadened our understanding of biological regulatory mechanisms in animals and plants. They show both evolutionary conserved and unique features across Metazoa. Here, we present the current status of the knowledge about the role of miRNA in development, growth, and physiology of teleost fishes, in comparison to other vertebrates. Infraclass Teleostei is the most abundant group among vertebrate lineage. Fish are an important component of aquatic ecosystems and human life, being the prolific source of animal proteins worldwide and a vertebrate model for biomedical research. We review miRNA biogenesis, regulation, modifications, and mechanisms of action. Specific sections are devoted to the role of miRNA in teleost development, organogenesis, tissue differentiation, growth, regeneration, reproduction, endocrine system, and responses to environmental stimuli. Each section discusses gaps in the current knowledge and pinpoints the future directions of research on miRNA in teleosts.

“…In medaka ( Oryzias latipes ), a distantly related teleost, miR-430 is not as abundant as in zebrafish; however, the miR-430 family displays a conserved role in early embryogenesis. Interestingly, the miR-430 family members in medaka are located on chromosome 4, which is also where the majority of zebrafish miR-430 family members are encoded (Thatcher et al, 2008; Tani et al, 2009). The difference in abundance between these two distantly related species may indicate an increased importance for the miR-430 in zebrafish related to the levels of maternal transcripts, but the positional and functional conservation nonetheless demonstrates importance in both species.…”

microRNAs (miRNAs) are small (∼22 nt) noncoding RNAs that have been shown to regulate gene expression post-transcriptionally. They function by pairing with the 3′ UTR of target mRNAs and repressing translation or by targeting the mRNA for degradation. miRNAs are involved in diverse aspects of development, maintenance, and disease, and are largely evolutionarily conserved in metazoans. Searching the genomes of organisms from viruses to worms to humans has revealed potentially thousands of miRNA genes. Understanding the patterns of genomic organization between species cannot only help to refine tools to identify new miRNAs, but also provide insight into miRNA biogenesis and function.
