Dissection of X chromosome dosage compensation for quantitative traits in sheep using different statistical models [PDF]

open access: yesScientific Reports
Since males and females have different number of X chromosome, different mechanisms have evolved to equalize dosage of gene products from the X chromosome between XX females and XY males.

MYC dosage compensation is mediated by miRNA-transcription factor interactions in aneuploid cancer

open access: yesiScience, 2021
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]

open access: yesPLoS Genetics, 2014
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 ...

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).

Genetic dosage compensation in a family with velo‐cardio‐facial/DiGeorge/22q11.2 deletion syndrome [PDF]

open access: yesAmerican Journal of Medical Genetics Part A, 2011
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

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 ...

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 ...

The status of dosage compensation in the multiple X chromosomes of the platypus. [PDF]

open access: yesPLoS Genetics, 2008
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 ...

Positive selection underlies Faster-Z evolution of gene expression in birds. [PDF]

open access: yes, 2015
The elevated rate of evolution for genes on sex chromosomes compared to autosomes (Fast-X or Fast-Z evolution) can result either from positive selection in the heterogametic sex, or from non-adaptive consequences of reduced relative effective population ...
