ZEA exerts toxic effects on reproduction and development by mediating Dio3os in mouse endometrial stromal cells.

Zearalenone (ZEA) and imprinted long noncoding RNAs (lncRNAs) are both closely related to reproduction and development. However, whether they have connections in regulating reproduction and development is not clear yet. The aim of this research is to investigate their relationship. lncRNA microarray was performed to analyze differentially expressed genes, and real-time quantitative polymerase chain reaction (PCR) was used to verify the accuracy of microarray analysis. Meanwhile, the technologies of rapid amplification of cDNA ends, RNA fluorescence in situ hybridization and bioinformatics were adopted to characterize the selected lncRNA. Analysis of lncRNA microarray showed lncRNAs and messenger RNAs related to reproduction and development were significantly differently expressed, and Dio3os was probably the target lncRNA. Then, the experiment of real-time quantitative PCR verified the accuracy of microarray data. Characterization of Dio3os showed Dio3os, an antisense lncRNA with 2312 bp and 15 open reading frames, was enriched in the cytoplasm. Our findings suggest ZEA probably exerts toxic effects on reproduction and development by mediating Dio3os.
