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 article reconstructed the evolution of the Y chromosome across eight mammals to identify biases in gene content and the selective pressures that preserved the surviving ancestral genes, and concluded that the gene content of Y chromosome became specialized through selection to maintain the ancestral dosage of homologous X-Y gene pairs that function as broadly expressed regulators of transcription, translation and protein stability.

TL;DR: Treatment strategies for hypertension and CVD that are tailored according to sex could lead to improved outcomes for affected patients.

Sex Hormones and Sex Chromosomes Cause Sex Differences in the Development of Cardiovascular Diseases.
TL;DR: This review summarizes recent evidence concerning hormonal and sex chromosome effects in obesity, atherosclerosis, aneurysms, ischemia/reperfusion injury, and hypertension by comparing the 2 sexes directly and breaking down sex into its component parts.

TL;DR: It is demonstrated that escape from XCI results in sex biases in gene expression, thus establishing incomplete XCI as a likely mechanism introducing phenotypic diversity6,7 and this updated catalogue of XCI across human tissues informs the understanding of the extent and impact of the incompleteness.

TL;DR: In situ Hi-C is used to probe the 3D architecture of genomes, constructing haploid and diploid maps of nine cell types, identifying ∼10,000 loops that frequently link promoters and enhancers, correlate with gene activation, and show conservation across cell types and species.

TL;DR: It is found that the boundaries of topological domains are enriched for the insulator binding protein CTCF, housekeeping genes, transfer RNAs and short interspersed element (SINE) retrotransposons, indicating that these factors may have a role in establishing the topological domain structure of the genome.

Gene Action in the X -chromosome of the Mouse ( Mus musculus L.)
TL;DR: Ohno and Hauschka1 showed that in female mice one chromosome of mammary carcinoma cells and of normal diploid cells of the ovary, mammary gland and liver was heteropyKnotic and suggested that the so-called sex chromatin was composed of one heteropyknotic X-chromosome.

ATAC-seq: A Method for Assaying Chromatin Accessibility Genome-Wide
TL;DR: This method probes DNA accessibility with hyperactive Tn5 transposase, which inserts sequencing adapters into accessible regions of chromatin, which can be used to infer regions of increased accessibility, as well as to map regions of transcription‐factor binding and nucleosome position.

X-inactivation profile reveals extensive variability in X-linked gene expression in females
TL;DR: A comprehensive X-inactivation profile of the human X chromosome is presented, representing an estimated 95% of assayable genes in fibroblast-based test systems, and suggests a remarkable and previously unsuspected degree of expression heterogeneity among females.
