Transcriptome analysis in early embryos upon depletion of the Topoisomerase 2/condensin II axis.

In , the chromosome compaction factors topoisomerase 2 (TOP-2) and condensin II have been shown to globally repress transcription in multiple contexts. Our group has previously reported that TOP-2 and condensin II repress transcription in the germline during larval starvation, oocyte maturation, and in germline progenitor cells of the early embryo. Here, we assess the transcriptome of early embryos treated with RNAi against TOP-2 and the condensin II subunit CAPG-2. We found 144 upregulated and 172 downregulated genes. Further analysis showed that the upregulated genes are mostly somatic, with a host of neuronal cells present in our tissue enrichment analysis.
