General lack of global dosage compensation in ZZ/ZW systems? Broadening the perspective with RNA-seq [PDF]

open access: yesBMC Genomics, 2011
Background Species with heteromorphic sex chromosomes face the challenge of large-scale imbalance in gene dose. Microarray-based studies in several independent male heterogametic XX/XY systems suggest that dosage compensation mechanisms are in place to ...

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 ...

Genetic compensation: A phenomenon in search of mechanisms. [PDF]

open access: yesPLoS Genetics, 2017
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).

Dosage-sensitive molecular mechanisms are associated with the tissue-specificity of traits and diseases

open access: yesComputational and Structural Biotechnology Journal, 2020
Hereditary diseases and complex traits often manifest in specific tissues, whereas their causal genes are expressed in many tissues that remain unaffected.

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 ...

Sex-specific trans-regulatory variation on the Drosophila melanogaster X chromosome. [PDF]

open access: yesPLoS Genetics, 2015
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]

open access: yesPLoS Genetics, 2012
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

Dosage compensation in birds [PDF]

open access: yes, 2001
The Z and W sex chromosomes of birds have evolved independently from the mammalian X and Y chromosomes [1]. Unlike mammals, female birds are heterogametic (ZW), while males are homogametic (ZZ).

Exploring the Complexity of Protein-Level Dosage Compensation that Fine-Tunes Stoichiometry of Multiprotein Complexes.

open access: yesPLoS Genetics, 2020
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 ...
