Enhanced chromatin accessibility of the dosage compensated Drosophila male X-chromosome requires the CLAMP zinc finger protein. [PDF]

open access: yesPLoS ONE, 2017
The essential process of dosage compensation is required to equalize gene expression of X-chromosome genes between males (XY) and females (XX). In Drosophila, the conserved Male-specific lethal (MSL) histone acetyltransferase complex mediates dosage ...

RANK signaling in osteoclast precursors results in a more permissive epigenetic landscape and sexually divergent patterns of gene expression [PDF]

open access: yesPeerJ, 2023
Background Sex is an important risk factor in the development of osteoporosis and other bone loss disorders, with women often demonstrating greater susceptibility than men. While variation in sex steroids, such as estradiol, accounts for much of the risk,

Deciphering the Role of the Barr Body in Malignancy: An insight into head and neck cancer

open access: yesSultan Qaboos University Medical Journal, 2018
X chromosome inactivation is the epitome of epigenetic regulation and long non-coding ribonucleic acid function. The differentiation status of cells has been ascribed to X chromosome activity, with two active X chromosomes generally only observed in ...

Sex dependent glial-specific changes in the chromatin accessibility landscape in late-onset Alzheimer’s disease brains

open access: yesMolecular Neurodegeneration, 2021
Background In the post-GWAS era, there is an unmet need to decode the underpinning genetic etiologies of late-onset Alzheimer’s disease (LOAD) and translate the associations to causation.

The epigenome of evolving Drosophila neo-sex chromosomes: dosage compensation and heterochromatin formation. [PDF]

open access: yesPLoS Biology, 2013
Sex chromosomes originated from autosomes but have evolved a highly specialized chromatin structure. Drosophila Y chromosomes are composed entirely of silent heterochromatin, while male X chromosomes have highly accessible chromatin and are ...

Chromatin accessibility, not 5mC methylation covaries with partial dosage compensation in crows.

open access: yesPLoS Genetics, 2023
The evolution of genetic sex determination is often accompanied by degradation of the sex-limited chromosome. Male heterogametic systems have evolved convergent, epigenetic mechanisms restoring the resulting imbalance in gene dosage between diploid ...
