Large-Scale Analysis of X Inactivation Variations between Primed and Naïve Human Embryonic Stem Cells

open access: yesCells, 2022
X chromosome inactivation is a mammalian dosage compensation mechanism, where one of two X chromosomes is randomly inactivated in female cells. Previous studies have suggested that primed human embryonic stem cells (hESCs) maintain an eroded state of the

Evidence of influence of genomic DNA sequence on human X chromosome inactivation. [PDF]

open access: yesPLoS Computational Biology, 2006
A significant number of human X-linked genes escape X chromosome inactivation and are thus expressed from both the active and inactive X chromosomes. The basis for escape from inactivation and the potential role of the X chromosome primary DNA sequence ...

Large-scale population study of human cell lines indicates that dosage compensation is virtually complete. [PDF]

open access: yesPLoS Genetics, 2008
X chromosome inactivation in female mammals results in dosage compensation of X-linked gene products between the sexes. In humans there is evidence that a substantial proportion of genes escape from silencing.

Characterisation of inactivation domains and evolutionary strata in human X chromosome through Markov segmentation. [PDF]

open access: yesPLoS ONE, 2009
Markov segmentation is a method of identifying compositionally different subsequences in a given symbolic sequence. We have applied this technique to the DNA sequence of the human X chromosome to analyze its compositional structure.

Dynamics of the two heterochromatin types during imprinted X chromosome inactivation in vole Microtus levis.

open access: yesPLoS ONE, 2014
In rodent female mammals, there are two forms of X-inactivation - imprinted and random which take place in extraembryonic and embryonic tissues, respectively.

X chromosomes alternate between two states prior to random X-inactivation. [PDF]

open access: yesPLoS Biology, 2006
Early in the development of female mammals, one of the two X chromosomes is silenced in half of cells and the other X chromosome is silenced in the remaining half. The basis of this apparent randomness is not understood.

The X chromosome and sex-specific effects in infectious disease susceptibility

open access: yesHuman Genomics, 2019
The X chromosome and X-linked variants have largely been ignored in genome-wide and candidate association studies of infectious diseases due to the complexity of statistical analysis of the X chromosome.

Loss of p53 Causes Stochastic Aberrant X-Chromosome Inactivation and Female-Specific Neural Tube Defects

open access: yesCell Reports, 2019
Summary: Neural tube defects (NTDs) are common birth defects in humans and show an unexplained female bias. Female mice lacking the tumor suppressor p53 display NTDs with incomplete penetrance. We found that the combined loss of pro-apoptotic BIM and p53

Single-cell analysis reveals X upregulation is not global in pre-gastrulation embryos

open access: yesiScience, 2022
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

open access: yesFrontiers in Cell and Developmental Biology, 2019
RLIM/Rnf12 is an E3 ubiquitin ligase that has originally been identified as a transcriptional cofactor associated with LIM domain transcription factors.
