compensation between cells of females (XX karyotype) and males (XY). XCI is essential for …

[HTML][HTML] Progress toward understanding chromosome silencing by Xist RNA

N Brockdorff, JS Bowness, G Wei - Genes & development, 2020 - genesdev.cshlp.org

Escape from X-chromosome inactivation: an evolutionary perspective

BJ Posynick, CJ Brown - Frontiers in cell and developmental biology, 2019 - frontiersin.org
Sex chromosomes originate as a pair of homologus autosomes that then follow a general
pattern of divergence. This is evident in mammalian sex chromosomes, which have …

The X chromosome in space

T Jégu, E Aeby, JT Lee - Nature Reviews Genetics, 2017 - nature.com
Extensive 3D folding is required to package a genome into the tiny nuclear space, and this
packaging must be compatible with proper gene expression. Thus, in the well-hierarchized …
