Abnormal dosage compensation of reporter genes driven by the Drosophila glass multiple reporter (GMR) enhancer-promoter. [PDF]
PLoS ONE, 2011 In Drosophila melanogaster the male specific lethal (MSL) complex is required for upregulation of expression of most X-linked genes in males, thereby achieving X chromosome dosage compensation.

Partial Dosage Compensation in Strepsiptera, a Sister Group of Beetles [PDF]
, 2015 Sex chromosomes have evolved independently in many different taxa, and so have mechanisms to compensate for expression differences on sex chromosomes in males and females. Different clades have evolved vastly different ways to achieve dosage compensation,

Variable dosage compensation is associated with female consequences of an X-linked, male-beneficial mutation [PDF]
, 2021 Funding:TJH was supported by a PhD studentship from the University of St Andrews School of Biology. The study received funding from the UK Natural Environment Research Council to NWB and JGR (NE/T0006191/1) and NWB (NE/L011255/1, NE/I027800/1).Recent ...

Translating dosage compensation to trisomy 21 [PDF]
Nature, 2013 Down's syndrome is a common disorder with enormous medical and social costs, caused by trisomy for chromosome 21. We tested the concept that gene imbalance across an extra chromosome can be de facto corrected by manipulating a single gene, XIST (the X-inactivation gene).

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

Compensation of dosage-sensitive genes on the chicken Z chromosome [PDF]
, 2016 In many diploid species, sex determination is linked to a pair of sex chromosomes that evolved from a pair of autosomes. In these organisms, the degeneration of the sex-limited Y or W chromosome causes a reduction in gene dose in the heterogametic sex ...

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Large-scale population study of human cell lines indicates that dosage compensation is virtually complete. [PDF]
PLoS Genetics, 2008 X chromosome inactivation in female mammals results in dosage compensation of X-linked gene products between the sexes. In humans there is evidence that a substantial proportion of genes escape from silencing.

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining
Molecular Oncology, EarlyView.IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Absence of X-chromosome dosage compensation in the primordial germ cells of Drosophila embryos
Scientific Reports, 2021 Dosage compensation is a mechanism that equalizes sex chromosome gene expression between the sexes. In Drosophila, individuals with two X chromosomes (XX) become female, whereas males have one X chromosome (XY).
