Ctcf pluripotency
WebThe double homeobox (Dux) gene, encoding a double homeobox transcription factor, is one of the key drivers of totipotency in mice. Recent studies showed Dux was temporally expressed at the 2-cell stage and acted as a transcriptional activator during zygotic genome activation (ZGA) in embryos. A similar activation occurs in mouse embryonic stem cells, … WebThe X chromosome that now contains the pluripotency factors and CTCF proteins will continue to express the Tsix RNA and will remain active. The other X chromosome (without the pluripotency factors and CTCF proteins) turns off Tsix expression and begins to express the Xist RNA. As a result, the X chromosome that expresses Xist will be …
