X Chromosome Inactivation | Learn Science at Scitable - Nature
A prime example of X inactivation is in the coat-color patterning of tortoiseshell or calico cats (Figure 1). In cats, the fur pigmentation gene is X-linked, ...
X-inactivation is a process by which one of the copies of the X chromosome is inactivated in therian female mammals. The inactive X chromosome is silenced ...
X-chromosome inactivation: the molecular basis of silencing
X-chromosome inactivation occurs randomly for one of the two X chromosomes in female cells during development. Inactivation occurs when RNA ...
Landscape of X chromosome inactivation across human tissues
Multiple transcriptome approaches, including single-cell sequencing, demonstrate that escape from X chromosome inactivation is widespread ...
X Chromosome Inactivation and Embryonic Stem Cells - NCBI
X chromosome inactivation (XCI) is a process required to equalize the dosage of X-encoded genes between female and male cells. XCI is initiated very early ...
X-inactivation (article) | Khan Academy
in Turner syndrome, a woman lacks part or all of one of her X chromosomes (leaving her with just one functional X). People with this disorder develop as females ...
X-Chromosome Inactivation and Related Diseases - PMC
X-chromosome inactivation (XCI) is the form of dosage compensation in mammalian female cells to balance X-linked gene expression levels of the two sexes.
X Inactivation and Escape: Epigenetic and Structural Features
X inactivation represents a complex multi-layer epigenetic mechanism that profoundly modifies chromatin composition and structure of one X ...
X-Inactivation - an overview | ScienceDirect Topics
Briefly, X chromosome inactivation is a process in female mammalian cells in which one copy of the X chromosome is inactivated. This ensures that females ...
X chromosome: MedlinePlus Genetics
This phenomenon is called X-inactivation or lyonization. X-inactivation ensures that people with two X chromosomes have only one functional copy ...
X chromosome inactivation in human development
ABSTRACT. X chromosome inactivation (XCI) is a key developmental process taking place in female mammals to compensate for the imbalance in the ...
Lyonization - National Human Genome Research Institute
Lyonization (also called X-inactivation) refers to the normal phenomenon in which one of the two X chromosomes in every cell of a female individual is ...
X Chromosome Inactivation - an overview | ScienceDirect Topics
X Chromosome Inactivation ... X Chromosome Inactivation refers to the process in females where one copy of the X chromosome is silenced to ensure balanced gene ...

X‐Chromosome Inactivation and Related Diseases - Sun - 2022
X-chromosome aneuploidy results in disease phenotypes in human: TS (45, X), Klinefelter syndrome (47, XXY), and triple X syndrome (47, XXX). For ...
Understanding the genetics of X chromosome inactivation
The X chromosome inactivation relies on epigenetic mechanisms. A non-coding RNA, called Xist (X-inactive specific transcript), is expressed in ...
Study challenges prior understanding of X chromosome inactivation
It was recently discovered that a unique form of X inactivation takes place during early embryonic development in humans, where XIST is expressed from both X ...
X Inactivation and Epigenetics: Vibrant Animation & Explanation
X inactivation is a type of gene dosage compensation. In humans, the sex chromosomes X and Y determine the sex of an individual – females have two X chromosomes ...
Human genes escaping X-inactivation revealed by single cell ...
The X-inactivation is an event that occurs independently for each cell. Thus, collecting expression data from single cells allows monitoring ...
X Chromosome Inactivation - iBiology
The X chromosome is many time larger than the Y chromosome. To compensate for this genetic inequality, female mammalian cells undergo X chromosome ...
