Popis: The effect of berberine (Ber) on in vitro fertilization (IVF) embryo development in pigs and the associated differential expression of microRNAs (miRNAs) in the embryo were investigated. NCSU-23 embryonic culture medium was used for a control group, while NCSU-23 embryonic culture medium added with Ber was used for a Ber group. The embryo development rates in these groups were determined, and the zygotes, 4- and 8-cell embryos, and blastocysts were collected for cDNA microarray analysis. The development rates of 2-, 4-, 8-cell embryos and blastocysts were significantly higher in the Ber group than those in the control group (p < 0.01). The differentially expressed miRNAs in the 8-cell versus the 4-cell stage in control group as well as in the 8-cell Ber group versus the 8-cell control group overlapped, and it was found that nine miRNAs were commonly upregulated and two of them were downregulated, while there was no overlap among the other groups. The target genes of Ber-regulated miRNAs at the 8-cell stage were mainly associated with the molecular pathway of nucleic acid and protein synthesis. These findings suggest that Ber may regulate the expression of miRNAs at the 8-cell stage, which is beneficial to provide material reserves for the maternal to zygote transition of porcine embryos, thereby increasing the porcine IVF embryo development rate.
