ABSTRACT
OBJECTIVE@#To explore the correlation between microRNA (miRNA) differential expression and quality of embryo.@*METHODS@#The miRNA expression profiles of 8 blastocysts were detected by a TaqMan microRNA array, and miRNAs with a stable expression were selected. Additional blastocysts were selected, and the candidate miRNA was detected by real-time PCR. Meanwhile, chromosomal abnormalities of the embryos were detected by using next-generation sequencing, and the results were compared.@*RESULTS@#The expression of mir-720, mir-372, mir-886-3p and mir-512-3p was higher than that of miR-145, which suggested that mir-720, mir-372, mir-886-3p and mir-512-3p are related to early embryo development. The expression of miR-145 and mir-886-3p were significantly lower in the normal chromosome group. With the threshold values of above 9 and 3 for the relative expression of miR-145 and mir-886-3p, respectively, there was no embryo without a chromosomal abnormality.@*CONCLUSION@#There is a correlation between the expression level of specific miRNA and chromosomal abnormalities of embryos, which may be used as a novel biomarker for embryo selection.
