Immunoglobulins and the X-chromosome [PDF]
BMJ, 1969 Serum levels of immunoglobulins (Ig) G, M, and A were determined in 28 women with an additional X-chromosome (XXX), and in equal numbers of age-matched normal women and men. Mean IgM levels were found to be highest in the XXX group, intermediate in normal women, and lowest in men; these differences were statistically significant.

Association of X Chromosome Aberrations with Male Infertility
Acta Medica Bulgarica, 2021 Male infertility is caused by spermatogenetic failure, clinically noted as oligoor azoospermia. Approximately 20% of infertile patients carry a genetic defect.

A second X chromosome contributes to resilience in a mouse model of Alzheimer’s disease
Science Translational Medicine, 2020 The second X chromosome confers resilience in a mouse model of Alzheimer’s disease potentially through the X-linked gene Kdm6a. The advantage of an extra X Whether sex chromosomes contribute to sex difference in Alzheimer’s disease (AD) is unknown. In AD,

X chromosome inactivation in human development
Development, 2020 X chromosome inactivation (XCI) is a key developmental process taking place in female mammals to compensate for the imbalance in the dosage of X-chromosomal genes between sexes.

G3: Genes, Genomes, Genetics, 2020 Mouse sex chromosomes are enriched for co-amplified gene families, present in tens to hundreds of copies. Co-amplification of Slx/Slxl1 on the X chromosome and Sly on the Y chromosome are involved in dose-dependent meiotic drive, however the role of ...

X-Chromosome Inactivation [PDF]
Current Biology, 1994 In female mammals, all X chromosomes except one are transcriptionally inactivated early in embryonic development. This is known as X-chromosome inactivation and is a form of dosage compensation, giving equal dosage of the products of X-linked genes in males and females. The mechanism is of considerable interest as an example of differential behavior of

Enhanced chromatin accessibility contributes to X chromosome dosage compensation in mammals
Genome Biology, 2021 Background Precise gene dosage of the X chromosomes is critical for normal development and cellular function. In mice, XX female somatic cells show transcriptional X chromosome upregulation of their single active X chromosome, while the other X ...

From Hi-C Contact Map to Three-dimensional Organization of Interphase Human Chromosomes [PDF]
Phys. Rev. X 11, 011051 (2021), 2020 The probability of two loci, separated by a certain genome length, being in contact can be inferred using the Chromosome Conformation Capture (3C) method and related Hi-C experiments. How to go from the contact map, a matrix listing the mean contact probabilities between a large number of pairs of loci, to an ensemble of three-dimensional structures is

Landscape of X chromosome inactivation across human tissues
Nature, 2016 X chromosome inactivation (XCI) silences transcription from one of the two X chromosomes in female mammalian cells to balance expression dosage between XX females and XY males. XCI is, however, incomplete in humans: up to one-third of X-chromosomal genes

Monosomy for the X chromosome [PDF]
Chromosome Research, 2009 Dosage compensation serves to equalize X chromosome gene expression in mammalian males and females and involves extensive silencing of the 2nd X chromosome in females. If dosage compensation mechanisms completely suppressed the 2nd X chromosome, then actual physical loss of this "eXtra" chromosome should have few consequences.
