Translatomes are more accurate than transcriptomes as indicators of gene expression profiles in cells, especially in cellular processes that cease transcriptional expression and rely on translational control, such as oocytes. Here, we developed a dual omics methodology to simultaneously examine gene expression using the transcriptomes and translatomes of single oocytes or embryos and identified a protein that can promote human oocyte maturation. First, we developed a transcriptome and translatome sequencing (T&T seq) strategy using single mouse oocytes and extended this method to human oocytes and early embryos. Many genes that are differentially expressed through translational control at different developmental stages and between two species were identified using this method. Overall, our dual omics methodology opens a new avenue for simultaneously assessing the transcriptome and translatome of a cell. |
