Demasculinization of the Anopheles gambiae X chromosome

BMC 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

Nature 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.

BRCA1-mediated repression of select X chromosome genes

Journal of Translational Medicine, 2004
Recently BRCA1 has been implicated in the regulation of gene expression from the X chromosome. In this study the influence of BRCA1 on expression of X chromosome genes was investigated.

The toll like receptor 7 pathway and the sex bias of systemic lupus erythematosus

Frontiers in Immunology
Systemic lupus erythematosus (SLE) predominately affects women with a ratio of females-to-males of about 9:1. The complement of sex chromosomes may play and important role in the mechanism of the sex bias.

Dynamic dosage changes in X-linked transposable elements during mammalian dosage compensation

Nature Communications
In mammals, X-linked dosage compensation involves X-chromosome inactivation to balance X chromosome dosage between males and females, and hyperactivation of the remaining X-chromosome (Xa-hyperactivation) to achieve X-autosome balance in both sexes ...
