X chromosome: expression and escape. [PDF]

open access: yesPLoS Genetics, 2009
Although there are some obvious differences between the X chromosome and the autosomes—such as the X chromosome being present in only one copy in males—the two types of chromosome are remarkably similar in their cytological appearance and gene density [1]. Genomic and transcriptomic studies of Drosophila, however, have revealed two major differences in

Demasculinization of the Anopheles gambiae X chromosome [PDF]

open access: yesBMC Evolutionary Biology, 2012
Background In a number of organisms sex-biased genes are non-randomly distributed between autosomes and the shared sex chromosome X (or Z). Studies on Anopheles gambiae have produced conflicting results regarding the underrepresentation of male-biased ...

Population variability in X-chromosome inactivation across 10 mammalian species [PDF]

open access: yesNature Communications
One of the two X-chromosomes in female mammals is epigenetically silenced in embryonic stem cells by X-chromosome inactivation. This creates a mosaic of cells expressing either the maternal or the paternal X allele.

Immunoglobulins and the X-chromosome [PDF]

open access: yesBMJ, 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 Parental Origin with Clinical Profile in Klinefelter Syndrome [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2015
Introduction: Several genomic imprinting mechanisms have been postulated to report the parent-of-origin in Klinefelter syndrome. It was stated in the literature, parental origin has an effect on behavioral phenotype of Klinefelter individuals, but the

Epigenetic-structural changes in X chromosomes promote Xic pairing during early differentiation of mouse embryonic stem cells

open access: yesBiophysics and Physicobiology, 2022
X chromosome inactivation center (Xic) pairing occurs during the differentiation of embryonic stem (ES) cells from female mouse embryos, and is related to X chromosome inactivation, the circadian clock, intra-nucleus architecture, and metabolism. However,

Association of X Chromosome Aberrations with Male Infertility

open access: yesActa Medica Bulgarica, 2021
Male infertility is caused by spermatogenetic failure, clinically noted as oligoor azoospermia. Approximately 20% of infertile patients carry a genetic defect.
