Dynamic dosage changes in X-linked transposable elements during mammalian dosage compensation [PDF]
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 ...

MYC dosage compensation is mediated by miRNA-transcription factor interactions in aneuploid cancer
Summary: We hypothesize that dosage compensation of critical genes arises from systems-level properties for cancer cells to withstand the negative effects of aneuploidy.

Sex-specific embryonic gene expression in species with newly evolved sex chromosomes. [PDF]
Sex chromosome dosage differences between females and males are a significant form of natural genetic variation in many species. Like many species with chromosomal sex determination, Drosophila females have two X chromosomes, while males have one X and ...

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 ...

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).

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 ...

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 ...

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

Proper control of gene expression levels upon various perturbations is a fundamental aspect of cellular robustness. Protein-level dosage compensation is one mechanism buffering perturbations to stoichiometry of multiprotein complexes through accelerated ...
