Abstract:

MicroRNAs (MiRNAs) are a class of short endogenous non-coding RNAs (NcRNAs) about 20 nucleotides (nt) in length. It has been well documented that miRNAs are vital regulators of post transcriptional regulation of genes in most eukaryotes involving in growth and development, cell differentiation and immune defense. Sea urchins and sea cucumbers belong to echinoderms which are higher marine invertebrates. They are not only important model organisms for studying the evolution of invertebrates to vertebrates, but also important fishery resources with high economic value. In recent years, exploring the regulatory functions and mechanisms of various miRNAs in the physiological and metabolic process of sea urchins and sea cucumbers has gradually become a hotspot in the field of sea urchin and sea cucumber research. In this paper, we reviewed the research results and progress of miRNAs in sea urchins and sea cucumbers in recent years, aiming to further enrich and improve the data system of miRNAs in sea urchins and sea cucumbers, as well as, provide reference materials for systematically understanding the sequence characteristics, biological functions and molecular mechanisms of miRNAs involved in regulating important physiological metabolism processes in sea urchins and sea cucumbers.

Key words: sea urchins, sea cucumbers, microRNA, growth and development, physiological metabolism
