SU(VAR)3-7 links heterochromatin and dosage compensation in Drosophila. [PDF]
In Drosophila, dosage compensation augments X chromosome-linked transcription in males relative to females. This process is achieved by the Dosage Compensation Complex (DCC), which associates specifically with the male X chromosome.

Transcription dosage compensation does not occur in Down syndrome [PDF]
Background The increase in DNA copy number in Down syndrome (DS; caused by trisomy 21) has led to the DNA dosage hypothesis, which posits that the level of gene expression is proportional to the gene’s DNA copy number.

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 ...

A sequence motif enriched in regions bound by the
Background In Drosophila melanogaster, dosage compensation is mediated by the action of the dosage compensation complex (DCC). How the DCC recognizes the fly X chromosome is still poorly understood.

Gene dosage compensation: Origins, criteria to identify compensated genes, and mechanisms including sensor loops as an emerging systems‐level property in cancer [PDF]
The gene dosage compensation hypothesis presents a mechanism through which the expression of certain genes is modulated to compensate for differences in the dose of genes when additional chromosomes are present.

Targeting determinants of dosage compensation in Drosophila. [PDF]
The dosage compensation complex (DCC) in Drosophila melanogaster is responsible for up-regulating transcription from the single male X chromosome to equal the transcription from the two X chromosomes in females.

Sex Chromosome Dosage Compensation in Insects [PDF]
Dosage compensation (DC) is of crucial importance in balancing the sex-linked gene expression between males and females. It serves to guarantee that the proteins or other enzymatic products encoded by the sex chromosome exhibit quantitative parity ...

Restricting dosage compensation complex binding to the X chromosomes by H2A.Z/HTZ-1. [PDF]
Dosage compensation ensures similar levels of X-linked gene products in males (XY or XO) and females (XX), despite their different numbers of X chromosomes.

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

Elastic dosage compensation by X-chromosome upregulation [PDF]
The concerted dynamics of X-chromosome upregulation and X-chromosome inactivation, which collectively balance X-chromosome expression, are not well understood.
