Abstract:

MicroRNAs(miRNA)are small non-coding RNA encoded by endogenous genes. They play important role in various life activities including cell apoptosis,development and growth,metabolism and so on. Recent studies revealed that the changing of miRNA expressions,when organisms are exposing to environmental pollutants such as heavy metal,organic pollutants and so on,may affect the expressions of target genes,further regulate the toxic effect of organism to exogenous pollutants. This review summarizes the research progress of miRNA involved in aquatic animals under different environmental pollutants exposure as well as its mechanisms,discusses and prospects the future research direction of miRNA,aiming to provide some references for studying the stress tolerance of aquatic animals.

Key words: microRNA, environmental pollutants, aquatic animals
