Mammals use X chromosome inactivation to compensate for the sex difference in numbers of X chromosomes. A relatively unexplored question is how the active X is protected from inactivation by its own XIST gene, the long non-coding RNA, which initiates ...

Single-cell analysis reveals X upregulation is not global in pre-gastrulation embryos
Summary: In mammals, transcriptional inactivation of one X chromosome in female compensates for the dosage of X-linked gene expression between the sexes.

Rlim/Rnf12, Rex1, and X Chromosome Inactivation
RLIM/Rnf12 is an E3 ubiquitin ligase that has originally been identified as a transcriptional cofactor associated with LIM domain transcription factors.

X-Chromosome Inactivation: A Crossroads Between Chromosome Architecture and Gene Regulation.
In somatic nuclei of female therian mammals, the two X chromosomes display very different chromatin states: One X is typically euchromatic and transcriptionally active, and the other is mostly silent and forms a cytologically detectable heterochromatic ...

Genes that escape from X‐chromosome inactivation: Potential contributors to Klinefelter syndrome
One of the two X chromosomes in females is epigenetically inactivated, thereby compensating for the dosage difference in X‐linked genes between XX females and XY males.

Escape from X chromosome inactivation and female bias of autoimmune diseases
Generally, autoimmune diseases are more prevalent in females than males. Various predisposing factors, including female sex hormones, X chromosome genes, and the microbiome have been implicated in the female bias of autoimmune diseases.

Systematic allelic analysis defines the interplay of key pathways in X chromosome inactivation
Xist RNA, the master regulator of X chromosome inactivation, acts in cis to induce chromosome-wide silencing. Whilst recent studies have defined candidate silencing factors, their relative contribution to repressing different genes, and their ...

Clinical expression of Menkes disease in females with normal karyotype
Background Menkes Disease (MD) is a rare X-linked recessive fatal neurodegenerative disorder caused by mutations in the ATP7A gene, and most patients are males.

Conversion of random X-inactivation to imprinted X-inactivation by maternal PRC2
Imprinted X-inactivation silences genes exclusively on the paternally-inherited X-chromosome and is a paradigm of transgenerational epigenetic inheritance in mammals. Here, we test the role of maternal vs.
