Abstract:

The aim of this study was to investigate the effect of vitrification on gene expression in porcine parthenogenetic activation (PA) blastocysts. In this study, porcine PA blastocysts were divided into fresh, vitrification group Ⅰ and vitrification group Ⅱ according to the experimental treatments, and then 3 well-morphologised blastocysts were selected from each group and analysed by transcriptome sequencing using Smart-seq2 single-cell full-length transcriptome sequencing technology. As a result, compared with the fresh group, a total of 772 differential expression genes (DEGs) were identified in the vitrification group Ⅰ. GO and KEGG enrichment analysis results showed that these DEGs were related to cellular lipid metabolic process, cell glucose homeostasis, MAPK signaling pathway, PI3K-Akt signaling pathway, etc. Compared with the fresh group, a total of 1 613 DEGs were identified in the vitrification group Ⅱ, which mainly related to gluconeogenesis, metabolic pathways, biosynthesis of amino acids, etc. Compared with the vitrification group Ⅰ, 822 DEGs were identified in the vitrification group Ⅱ, which mainly involved in pyruvate metabolic process, N-Glycan biosynthesis, cellular senescence, etc. In summary, this study revealed the effects of vitrification on the expression of genes related to lipid metabolism, energy metabolism, MAPK signalling pathway and other related genes in porcine PA blastocysts based on Smart-seq2 single-cell full-length transcriptome sequencing technology.
