Landscape of X chromosome inactivation across human tissues

Nature, 550(7675), 244–248.

MeSH headings : Chromosomes, Human, X / genetics; Female; Genes, X-Linked / genetics; Genome, Human / genetics; Genomics; Humans; Male; Organ Specificity / genetics; Phenotype; Sequence Analysis, RNA; Single-Cell Analysis; Transcriptome / genetics; X Chromosome Inactivation / genetics
TL;DR: It is shown that incomplete XCI affects at least 23% of X-chromosomal genes, identified seven genes that escape XCI with support from multiple lines of evidence and demonstrated that escape from XCI results in sex biases in gene expression, establishing incomplete X CI as a mechanism that is likely to introduce phenotypic diversity.

TL;DR: This work curated an extensive set of ADAR1 and ADAR2 targets and showed that many editing sites display distinct tissue-specific regulation by the ADAR enzymes in vivo, suggesting stronger cis-directed regulation of RNA editing for most sites, although the small set of conserved coding sites is under stronger trans-regulation.
