Inhibition of aberrant DNA re-methylation improves development of cloned embryos (RNA-Seq data set 2)

Project description:Somatic cell nuclear transfer (SCNT) enables the genome of a differentiated somatic cell to be reprogrammed to totipotency. However, this process is extremely inefficient, and the underlying mechanism of the epigenetic rearrangements following SCNT remains largely unknown. Here, we generated a genome-wide DNA methylome of mouse SCNT preimplantation embryos. Surprisingly, we identified widespread re-methylated regions (rDMRs) in 2- to 4-cell stage cloned embryos, which caused mis-expression of genes and retrotransposons important for zygotic genome activation and embryo development. Knocking-down DNA methyltransferases can specifically rescue the re-methylation defects of SCNT embryos and evidently improve the poor developmental capacity of cloned embryos. In addition, inactivation of DNA methyltransferases combined with overexpression of histone demethylases led to a more significant reduction in DNA methylation as well as exhibited a synergistic enhancement effect on the full-term development of nuclear transfer embryos. Our study therefore reveals that aberrant re-methylation functions as an unavoidable barrier for SCNT embryo development, and that the removal of multiple epigenetic barriers would be a promising approach to achieve the highest cloning efficiency.

Expression data from mouse preimplantation cloned embryos

Project description:Transcriptiome analysis is an excellent approach to understand the mechanism underlying nuclear reprogramming in somatic-cell-cloned embryos. Analysis of the transcriptomic data from the oocyte to blastocyst stage revealed that specific genes were inappropriately reprogrammed at each stage. Sertoli cell-cloned embryos appear to develop normally because the progression of incorrect reprogramming is concealed throughout development. The time-lapse gene expression profiles provide valuable information for understanding reprogramming in SCNT embryos.
