Sex-specific trans-regulatory variation on the Drosophila melanogaster X chromosome. [PDF]
The X chromosome constitutes a unique genomic environment because it is present in one copy in males, but two copies in females. This simple fact has motivated several theoretical predictions with respect to how standing genetic variation on the X ...

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

Identification of chromatin-associated regulators of MSL complex targeting in Drosophila dosage compensation. [PDF]
Sex chromosome dosage compensation in Drosophila provides a model for understanding how chromatin organization can modulate coordinate gene regulation. Male Drosophila increase the transcript levels of genes on the single male X approximately two-fold to

Genetic compensation: A phenomenon in search of mechanisms. [PDF]
Several recent studies in a number of model systems including zebrafish, Arabidopsis, and mouse have revealed phenotypic differences between knockouts (i.e., mutants) and knockdowns (e.g., antisense-treated animals).

Genetic dosage compensation in a family with velo‐cardio‐facial/DiGeorge/22q11.2 deletion syndrome [PDF]
AbstractCytogenetic studies of a male child carrying the 22q11.2 deletion common in patients with velo‐cardio‐facial/DiGeorge syndrome showed an unexpected rearrangement of the 22q11.2 region in his normal appearing mother. The mother carried a 3 Mb deletion on one copy and a reciprocal, similar sized duplication on the other copy of chromosome 22q11.2

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

The status of dosage compensation in the multiple X chromosomes of the platypus. [PDF]
Dosage compensation has been thought to be a ubiquitous property of sex chromosomes that are represented differently in males and females. The expression of most X-borne genes is equalized between XX females and XY males in therian mammals (marsupials ...

A General Mechanism for Network-Dosage Compensation in Gene Circuits [PDF]
Coping with variations in network dosage is crucial for maintaining optimal function in gene networks. We explored how network structure facilitates network-level dosage compensation.
